Read the passage through 131carefully before making your choices. Each choice in the bank is132identified by a letter. Please mark the corresponding letter for each 133item on Answer Sheet 2 with a single line through the centre. You may 134not use any of the words in the bank more than once.135A rat or pigeon might not be the obvious choice to tend to someone 136who is sick, but these creatures have some 26 skills that could help the 137treatment of human diseases.1386 精品.资料Pigeons are often seen as dirty birds and an urban 27 , but they 139are just the latest in a long line of animals that have been found to 140have abilities to help humans. Despite having a brain no bigger than the 14128 of your index finger, pigeons have a very impressive 29__ memory. 142Recently it was shown that they could be trained to be as accurate as 143humans at detecting breast cancer in images.144Rats are often 30 with spreading disease rather than 31 it, but 145this long-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 146different types of olfactory receptors （嗅觉感受器）, whereas humans 147only have 100 to 200 types. This gives rats the ability to detect __33 148smells. As a result, some rats are being put to work to detect TB（肺149结核）. When the rats detect the smell, they stop and rub their legs to 15034 a sample is infected.151Traditionally, a hundred samples would take lab technicians more 152than two days to 35 , but for a rat it takes less than 20 minutes. This 153rat detection method doesn't rely on specialist equipment. It is also 154more accurate — the rats are able to find more TB infections and, 155therefore, save more lives.156A) associated I) slight157B) examine J) specify158C) indicate K) superior159D) nuisance L) suspicious160E) peak M) tip161F) preventing N) treated162G) prohibiting O) visual163H) sensitive1647 精品.资料Section B165Directions: In this section, you are going to read a passage with 166ten statements attached to it. Each statement contains information given 167in one of the paragraphs. Identify the paragraph from which the168information is derived. You may choose a paragraph more than once. Each 169paragraph is marked with a letter. Answer the questions by marking the 170corresponding letter on Answer Sheet 2.171Do In-Class Exams Make Students Study Harder?172Research suggests they may study more broadly for the unexpected 173rather than search for answers.174[A] I have always been a poor test-taker. So it may seem rather 175strange that I have returned to college to finish the degree I left undone 176some four decades ago. I am making my way through Columbia University, 177surrounded by students who quickly supply the verbal answer while I am 178still processing the question.179[B] Since there is no way for me to avoid exams, I am currently 180questioning what kind are the most taxing and ultimately beneficial. I 181have already sweated through numerous in-class midterms and finals, and 182now I have a professor who issues take-home ones. I was excited when I 183learned this, figuring I had a full week to do the research, read the 184texts, and write it all up. In fact, I was still rewriting my midterm 185the morning it was due. To say I had lost the thread is putting it mildly. 186[C] As I was suffering through my week of anxiety, overthinking 187the material and guessing my grasp of it, I did some of my own polling 188among students and professors. David Eisenbach, who teaches a popular 189class on U.S. presidents at Columbia, prefers the in-class variety. He 190believes students ultimately learn more and encourages them to form study 191groups. “That way they socialize over history outside the class, which 192wouldn’t happen without the pressure of an in-class exam,” he explained, 1938 精品.资料“Furthermore, in-class exams force students to learn how to perform 194under pressure, and essential work skill.”195[D] He also says there is less chance of cheating with the196in-class variety. In 2012, 125 students at Harvard were caught up in a 197scandal when it was discovered they had cheated on a take-home exam for 198a class entitled “Introduction To Congress.” Some colleges have what 199they call an “honor code,” th ough if you are smart enough to get into 200these schools, you are either smart enough to get around any codes or 201hopefully, too ethical to consider doing so. As I sat blocked and clueless 202for two solid days, I momentarily wondered if I couldn’t just call an 203expert on the subject matter which I was tackling, or someone who took 204the class previously, to get me going.205[E] Following the Harvard scandal, Mary Miller, the former dean 206of students at Yale, made an impassioned appeal to her school’s207professors to refrain from take-hone exams. “Students risk health and 208well being, as well as performance in other end-of-term work, when faculty 209offers take-home exams without clear, time-limited boundaries,” she 210told me. “Research now shows that regular quizzes, short es says, and 211other assignments over the course of a term better enhance learning and 212retention.”213[F] Most college professors agree the kind of exam they choose 214largely depends on the subject. A quantitative-based one, for example, 215is unlikely to be sent home, where one could ask their older brothers 216and sisters to help. Vocational-type classes, such as computer science 217or journalism, on the other hand, are often more research-oriented and 218lend themselves to take-home testing. Chris Koch, who teaches “History 219of Broadcast Journalism” at Montgomery Community College in Rockville, 220Maryland, points out that reporting is about investigation rather than 221the memorization of minute details. “In my field, it’s not what you 222know—it’s what you know how to find out,” says Koch. “There is way 223too much information, and more coming all the time, for anyone to remember. 2249 精品.资料I want my students to search out the answers to questions by using all 225the resources available to them.226[G] Students’ test-form preferences vary, too, often depending 227on the subject and course difficulty. “I prefer take-home essays because 228it is then really about the writing, so you have time to edit and do more 229research,” says Elizabeth Dresser, a junior at Barnard. Then there is 230the stress factor. Francesca Haass, a senior at Middlebury, says, “I 231find the in-class ones are more stressful in the short term, but there 232is immediate relief as you swallow information like mad, and then you 233get to forget it all. Take-homes require thoughtful engagement which can 234lead to longer term stress as there is never a moment when the time is 235up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even 236considers take-homes true exams. “If you understand the material and 237have the ability to articulate (说出) your thoughts, they should be a 238breeze.”239[H] How students ultimately handle stress may depend on their 240personal test-taking abilities. There are people who always wait until 241the last minute, and make it much harder than it needs to be. And then 242there those who, not knowing what questions are coming at them, and having 243no resources to refer to, can freeze. And then there are we rare folks 244who fit both those descriptions.245[I] Yes, my advanced age must factor into the equation (等式), 246in part because of my inability to247access the information as quickly. As another returning student 248at Columbia, Kate Marber, told249me, “We are learning not only all this information, but250essentially how to learn again. Our251fellow students have just come out of high school. A lot has 252changed since we were last in25310 精品.资料school.”254[J] If nothing else, the situation has given my college son and 255me something to share, When I256asked his opinion on this matter, he responded, “I like in-class 257exams because the time is258already reserved, as opposed to using my free time at home to 259work on a test,” he responded.260It seems to me that a compromise would be receiving the exam 261questions a day or two in262advance, and then doing the actual test in class the ticking clock 263overhead.264[K] Better yet, how about what one Hunter College professor 265reportedly did recently for her final266exam: She encouraged the class not to stress or even study, 267promising that, “It is going to be a268piece of cake.” When the students came in, sharpened pencils 269in hand, there was not a blue270book in sight. Rather, they saw a large chocolate cake and they 271each were given a slice.27236. Elderly students find it hard to keep up with the rapid 273changes in education.27437. Some believe take-home exams may affect students'275performance in other courses.27638. Certain professors believe in-class exams are ultimately 277more helpful to students.27811 精品.资料39. In-class exams are believed to discourage cheating in exams. 27940. The author was happy to learn she could do some exams at home. 28041. Students who put off their work until the last moment often 281find the exams more difficult than282they actually are.28342. Different students may prefer different types of exams. 28443. Most professors agree whether to give an in-class or a 285take-home exam depends on type of286course being taught.28744. The author dropped out of college some forty years ago. 28845. Some students think take-home exams will eat up their free 289time.290Section C291Directions: There are 2 passages in this section. Each passage 292is followed by some questions or unfinished statements. For each of them 293there are four choices marked A), B), C) and D). You should decide on 294the best choice and mark the corresponding letter on Answer Sheet 2 with 295a single line through the centre.296Passage One297Questions 46 and 50 are based on the following passage.298That people often experience trouble sleeping in a different bed 299in unfamiliar surroundings is a phenomenon known as the “first-night” 300effect. If a person stays in the same room the following night they tend 301to sleep more soundly. Yuka Sasaki and her colleagues at Brown University 302set out to investigate the origins of this effect.30312 精品.资料Dr. Sasaki knew the first-night effect probably has something 304to do with how humans evolved. The puzzle was what benefit would be gained 305from it when performance might be affected the following day. She also 306knew from previous work conducted on birds and dolphins that these animals 307put half of their brains to sleep at a time so that they can rest while 308remaining alert enough to avoid predators (捕食者). This led her to wonder 309if people might be doing the same thing. To take a closer look, her team 310studied 35 healthy people as they slept in the unfamiliar environment 311of the university’s Department of Psychological Sciences. The312participants each slept in the department for two nights and were313carefully monitored with techniques that looked at the activity of their 314brains. Dr. Sasaki found, as expected, the participants slept less well 315on their first night than they did on their second, taking more than twice 316as long to fall asleep and sleeping less overall. During deep sleep, the 317participants’ brains behaved in a similar manner seen in birds and 318dolphins. On the first night only, the left hemispheres (半球) of their 319brains did not sleep nearly as deeply as their right hemispheres did. 320Curious if the left hemispheres were indeed remaining awake to 321process information detected in the surrounding environment, Dr. Sasaki 322re-ran the experiment while presenting the sleeping participants with 323a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular 324beeps of a different tone during the night. She worked out that, if the 325left hemisphere was staying alert to keep guard in a strange environment, 326then it would react to the irregular beeps by stirring people from sleep 327and would ignore the regularly timed ones. This is precisely what she 328found.32946. What did researchers find puzzling about the first-night 330effect?331A) To what extent it can trouble people. C) What circumstances 332may trigger it.33313 精品.资料B) What role it has played in evolution. D) In what way it can 334be beneficial.33547. What do we learn about Dr. Yuka Sasaki doing her research? 336A) She found birds and dolphins remain alert while asleep.337B) She found birds and dolphins sleep in much the same way. 338C) She got some idea from previous studies on birds and dolphins 339D) She conducted studies on birds’ and dolphins’ sleeping 340patterns.34148. What did Dr. Sasaki do when she first did her experiment? 342A) She monitored the brain activity of participants sleeping in 343a new environment.344B) She recruited 35 participants from her Department of345Psychological Sciences.346C) She studied the differences between the two sides of347participants’ brains.348D) She tested her findings about birds and dolphins on human 349subjects.35049. What did Dr. Sasaki do when re-running her experiment?351A) She analyzed the negative effect of irregular tones on brains. 352B) She recorded participants’ adaptation to changed353environment.354C) She exposed her participants to two different stimuli.355D) She compared the responses of different participants.35614 精品.资料50. What did Dr. Sasaki find about the participants in her357experiment?358A) They tended to enjoy certain tones more than others.359B) They tended to perceive irregular beeps as a threat.360C) They felt sleepy when exposed to regular beeps.361D) They differed in their tolerance of irregular tones.362Passage Two363Questions 51 to 55 are based on the following passage.364It’s time to reevaluate how women handle confl ict at work. Being 365overworked or over-committed at home and on the job will not get you where 366you want to be in life. It will only slow you down and hinder your career 367goals.368Did you know women are more likely than men to feel exhausted? 369Nearly twice as many women than men ages 18-44 reported feeling “very 370tired” or “exhausted”, according to a recent study.371This may not be surprising given that this is the age range when 372women have children. It's also the age range when many women are trying 373to balance careers and home. One reason women may feel exhausted is that 374they have a hard time saying "no." Women want to be able todo it all 375volunteer for school parties or cook delicious meals-and so their answer 376to any request is often “Yes, I can.”377Women strugg le to say “no” in the workplace for similar reasons, 378including the desire to be liked by their colleagues. Unfortunately, this 379inability to say "no" may be hurting women's heath as well as their career. 380At the workplace, men use conflict as a way to position themselves, 381while women often avoid conflict or strive to be the peacemaker, because 38215 精品.资料they don't want to be viewed as aggressive or disruptive at work. For 383example, there’s a problem that needs to be addressed immediately, 384resulting in a dispute over should be the one to fix it. Men are more 385likely to face that dispute from the perspective of what benefits them 386most, whereas women may approach the same dispute from the perspective 387of what's the easiest and quickest way to resolve the problem-even388if that means doing the boring work themselves.389This difference in handling conflict could be the deciding factor 390on who gets promoted to a leadership position and who does not. Leaders 391have to be able to delegate and manage resources wisely –including staff 392expertise. Shouldering more of the workload may not earn you that393promotion. Instead, it may highlight your inability to delegate394effectively.39551. What does the author say is the problem with women?396A) They are often unclear about the career goals to reach.397B) They are usually more committed at home than on the job. 398C) They tend to be over-optimistic about how far they could go. 399D) They tend to push themselves beyond the limits of their 400ability.40152. Why do working women of child-bearing age tend to feel drained 402of energy?403A) They struggle to satisfy the demands of both work and home. 404B) They are too devoted to work and unable to relax as a result. 405C) They do their best to cooperate with their workmates.406D) They are obliged to take up too many responsibilities.40716 精品.资料53. What may hinder the future prospects of career women?408A) Their unwillingness to say “no”.409B) Their desire to be considered powerful.410C) An underestimate of their own ability.411D) A lack of courage to face challenges.41254. Men and woman differ in their approach to resolving workplace 413conflicts in that______.414A) women tend to be easily satisfied415B) men are generally more persuasive416C) men tend to put their personal interests first417D) women are much more ready to compromise41855. What is important to a good leader?419A) A dominant personality. C) The courage to admit failure420B) The ability to delegate.

Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors (嗅觉感受器), whereas humans only have 100 to 200 types. This gives rats the ability to detect 33 smells. As a result, some rats are being put to work to detect TB (肺结核). When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate – the rats are able to find more TB infections and, therefore, save more lives.A) associatedB) examineC) indicateD) nuisanceE) peakF) preventingG) prohibitingH) sensitive I) slightJ) specify K) superior L) suspicious M) tipN) treated O) visualSection BDirections: In this section, you are going to read a passage with ten statements attached to it.

Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Do In-Class Exams MakeStudents Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.A) I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.B) Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issuestake-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.C) As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. “That way they socialize over history outside the class, which wouldn't happen without the pressure of an in-class exam,” he explained. “Furthermore, in-class exams force students to learn how to perform under pressure, an essential work skill.”D) He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled “Introduction To Congress.” Some colleges have what they call an “honor code,” though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn't just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.E) Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school's professors to refrain from take-home exams. “Students risk health and well being, as well as performance in otherend-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,” she told me. “Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”F) Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches “History of Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “In my field, it's not wha t you know – it's what you know how to find out,” says Koch. “There is way too much information, and morecoming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.”G) Students' test-form preferences vary, too, often depending on the subject and course difficulty. “I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research,” says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. “If you understand the materi al and have the ability to articulate (说出) your thoughts, they should be a breeze.”H) How students ultimately handle tests may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there are those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.I) Yes, my advanced age must factor into the equation (等式), in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, “We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school.A lot has changed since we were last in school.”J) If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, “I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test,” he responded. It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class with the ticking clock overhead.K) Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, “It is going to be a piece of cake.” When the students came in, sh arpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students' performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult than they actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on the type of course being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night” effect. If a person stays in the same room the following night, they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants' brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people.B) What role it has played in evolution.C) What circumstances may trigger it.D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphins.D) She conducted studies on birds' and dolphins' sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants' brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants' adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants.50. What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It's time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18–44 reported feeling “very tired” or “exhausted”, according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying “no.” Women want to be able to do it all – volunteer for school parties or cook delicious meals –and so their answer to any request is often “Yes, I can.”Women struggle to say “no” in the workplace for similar reasons, i ncluding the desire to be liked by their colleagues. Unfortunately, this inability to say “no” may be hurting women's health as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there's a problem that needs to be addressed immediately, resulting in a dispute over who should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem – even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely – including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51. What does the author say is the problem with women?A) They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A) They struggle to satisfy the demands of both work and home.B) They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D) They are obliged to take up too many responsibilities.53. What may hinder the future prospects of career women?A) Their unwillingness to say “no”.B) Their desire to be considered powerful.C) An underestimate of their own ability.D) A lack of courage to face challenges.54. Men and women differ in their approach to resolving workplace conflicts in that ______.A) women tend to be easily satisfiedB) men are generally more persuasiveC) men tend to put their personal interests firstD) women are much more ready to compromise55. What is important to a good leader?A) A dominant personality.B) The ability to delegate.C) The courage to admit failure.D) A strong sense of responsibility.Part IV TranslationDirections: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a “disease.”On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.“It unties the hands of the pharmaceutical(制药的)industry so that they can begin treating the disease and not just the side effects,”he said.“Right now, people think of aging as natural and something you can’t control,”he said. “IN academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.”But if aging were recognized as a disease, he said,“It would attract funding and change the way we do health care. What matters is understand that aging is curable.”“It was always known that the body accumulates damage,”he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions.”Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespancan be increased, which some researchers suggest is possible. Hayflick is not among them.“There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,”Hayflick said.“Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years.”46. Whatdo people generally believe about aging?A) It should cause not alarm whatsoever.B) They just cannot do anything about it.C) It should be regardedas a kind of disease.D) They can delay it with advances in science.47.How do many scientists view aging now?A) It might be prevented and treated. C) It results from a vitamin deficiency.B) It can be as risky as heart disease. D) It is an irreversible biological process.48. What does Alex Zhavoronkov think of “describing aging as a disease”?A) It will prompt people to take aging more seriously.B) It will greatly help reduce the side effects of aging.C) It will free pharmacists from the conventional beliefs about aging.D) It will motivate doctors and pharmacists to find ways to treat aging.49. What do we learn about the medical community?A) They now have a strong interest in research on aging.B) They differ from the academic circles in their view on aging.C) They can contribute to people’s health only to a limited extent.D) They have ways to intervene in people’s aging process.50. What does Professor Leonard Hayflick believe?A) The human lifespan cannot be prolonged.B) Aging is hardly separable from disease.C) Few people can live up to the age of 92.D) Heart disease is the major cause of aging.Passage TwoQuestions 51 to 55 are based on the following passage.Female applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts. Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring(指导), and have better odds of being hired. Studies show they’re also perceived as more competent than women in STEM (Science, Technology, Engineering, and Mathematics) fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too.“Say, you know, this is the best student I’ve ever had,” says Kuheli Dutt, a social scientist and diversity officer at Columbia University’s Lamont campus. “Compare those excellent letters with a merely good letter: ‘The candidate was productive, or inte lligent, or a solid scientist or something that’s clearly solid praise,’ but nothing that singles out the candidate as exceptional or one of a kind.”Dutt and her colleagues studied more than 1,200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared withtheir male counterparts. That includes letters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt says they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than out-standing letters of recommendation.“We're not trying to assign blame or criticize anyone or call anyone consciously sexist. Rather, the point is to use the results of this study toopen upmeaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level.”Which may lead to some recommendations for the letter writers themselves.51. What do we learn about applicants to postdoctoral positions in geosciences?A)There are many more men applying than women.B)Chances for women to get the positions are scarce.C)More males than females are likely to get outstanding letters of recommendation.D)Male applicants have more interest in these positions than their female counterparts.52. What do studies about men and women in scientific research show?A) Women engaged in postdoctoralwork are quickly catching up.B) Fewer women are applying for postdoctoralpositions due to gender bias.C) Men are believed to be better able to excel in STEM disciplines.D) Women who are keenly interested in STEM fields are often exceptional.53. What do the studies find about the recommendation letters for women applicants?A) They are hardly ever supported by concrete examples.B) They contain nothing that distinguishes the applicants.C) They provide objective information without exaggeration.D) They are often filled with praise for exceptional applicants.54. What did Dutt and her colleagues do with the more than 1,200 letters of recommendation?A) They asked unbiased scholars to evaluate them.B) They invited women professionals to edit them.C) They assigned them randomly to reviewers.D) They deleted all information about gender.55. What does Dutt aim to do with her study?A) Raise recommendation writers’awareness of gender bias in their letters.B) Open up fresh avenues for women post-doctors to join in reaserach work.C) Alert women researchers to all types of gender bias in the STEM disciplines.D) Start a public discussion on how to raise women’s status in academic circles.Part Ⅳ Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors (嗅觉感受器), whereas humans only have 100 to 200 types. This gives rats the ability to detect 33 smells. As a result, some rats are being put to work to detect TB (肺结核) . When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 ,but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate —the rats are able to find more TB infections and, therefore, save more lives.A) associatedB) examineC) indicate D) nuisanceE) peakF) preventingG) prohibitingH) sensitiveI) slightJ) specifyK) superiorL) suspiciousM) tipN) treatedO) visualSection BDirections: In this section, you are going to read a passage with ten statements attached to it.

Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A] I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B] Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C] As I was suffering through my week of anxiety, over thinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. “That way they socialize over history outside the class, which wouldn’t happen without the pressure of an in-class exam,” he explained, “Furthermore, in-class exams force students to learn how to perform under pressure, and essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled “Introduction To Congress.” Some colleges have what they call an “honor code,” though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I satblocked and clueless for two solid days, I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.[E] Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school’s professors to refrain from take-hone exams. “Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,” she told me. “Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”[F] Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches “History of Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “ In my field, it’s not what you know—it’s what you know how to find out,” says Koch. “ There is way too much information, and more coming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.”[G] Students’ test-form preferences vary, too, often depending on the subject and course difficulty. “ I prefer take-home essays because it is then really about the writing, so you have time to edit and do more research,” says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “ I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. “ If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze.”[H] How students ultimately handle stress may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs tobe. And then there those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.[I] Yes, my advanced age must factor into the equation (等式), in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, “ We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school.”[J] If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, “ I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test,” he responded. It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, “ It is going to be apiece of cake.” When the students came in, sharpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students' performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult than they actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type of course being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questionsor unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night”effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people. C) What circumstances may trigger it.B) What role it has played in evolution. D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphins.D) She conducted studies on birds’ and dolphins ‘ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants’brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants’ adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants.50. What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It’s time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling “ very tired ” or “ exhausted ”, according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying “ no." Women want to be able to do it all volunteer for school parties or cook delicious meals-and so their answer to any request is often “ Yes, I can.”Women struggle to say “ no " in the workplace for similar reasons, including the desire to be liked by their colleagues. Unfortunately, this inability to say “ no " may be hurting women's health as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there’s a problem that needs to be addressed immediately, resulting in a dispute over should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem-even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely –including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51. What does the author say is the problem with women?A) They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A) They struggle to satisfy the demands of both work and home.B) They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D) They are obliged to take up too many responsibilities.53. What may hinder the future prospects of career women?A) Their unwillingness to say “ no ".B) Their desire to be considered powerful.C) An underestimate of their own ability.D) A lack of courage to face challenges.54. Men and woman differ in their approach to resolving workplace conflicts in that______.A) women tend to be easily satisfied C) men tend to put their personal interests firstB) men are generally more persuasive D) women are much more ready to compromise55. What is important to a good leader?A) A dominant personality. C) The courage to admit failure.B) The ability to delegate. D) A strong sense of responsibility.Part ⅣTranslation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some 26 skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban 27 , but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29__ memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but thislong-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors （嗅觉感受器）, whereas humans only have 100 to 200 types. This gives rats the ability to detect __33 smells. As a result, some rats are being put to work to detect TB（肺结核）. When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate — the rats are able to find more TB infections and, therefore, save more lives.A) associated I) slightB) examine J) specifyC) indicate K) superiorD) nuisance L) suspiciousE) peak M) tipF) preventing N) treatedG) prohibiting O) visualH) sensitiveSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in oneof the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A] I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B] Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C] As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. ―That way they socialize over history outside the class, which wouldnhappen without the pressure of an in-c lass exam,‖ he explained,―Furthermore, in-class exams force students to learn how to perform underpressure, and essential work skill.‖[D] He also says there is less chance of cheating with the in-classvariety. In 2012, 125 students at Harvard were caught up in a scandal whenit was discovered they had cheated on a take-home exam for a class entitledonor―Introduction To Congress.‖ Some colleges have what they call an ―ｈcode,‖ though if you are smart enough to get into these schools, you areeither smart enough to get around any codes or hopefully, too ethical toconsider doing so. As I sat blocked and clueless for two solid days, Imomentarily wondered if I couldn‘ｔjust call an expert on the subject matterwhich I was tackling, or someone who took the class previously, to get megoing.[E] Following the Harvard scandal, Mary Miller, the former dean ofofessors tostudents at Yale, made an impassioned appeal to her school‘s prrefrain from take-hone exams. ―Students risk health and well being, as wellas performance in other end-of-term work, when faculty offers take-homeexams without clear, time-limited boundaries,‖ she told me. ―Research now shows that regular quizzes, short essays, and other assignments over thecourse of a term better enhance learning and retention.‖[F] Most college professors agree the kind of exam they choose largelydepends on the subject. A quantitative-based one, for example, is unlikely tobe sent home, where one could ask their older brothers and sisters to help.Vocational-type classes, such as computer science or journalism, on theother hand, are often more research-oriented and lend themselves totake-home testing. Chris Koch, who te aches ―History of BroadcastJournalism‖ at Montgomery Community College in Rockville, Maryland,points out that reporting is about investigation rather than the memorizationof minute details. ―In my field, it‘s not what you know—it‘s what y how to find out,‖ says Koch. ―There is way too much information, and more coming all the time, for anyone to remember. I want my students to searchout the answers to questions by using all the resources available to them.-form preferences vary, too, often depending on the[G] Students‘ test-home essays because it is thensubject and course difficulty. ―I prefer takereally about the writing, so you have time to edit and do more research,says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor.-class ones areFrancesca Haass, a senior at Middlebury, says, ―I find the inmore stressful in the short term, but there is immediate relief as you swallowinformation like mad, and then you get to forget it all. Take-homes requirethoughtful engagement which can lead to longer term stress as there is nevera moment when the time is up.‖ Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. ―If youunderstand the material and have the ability to articulate (说出) yourthoughts, they should be a breeze.‖[H] How students ultimately handle stress may depend on theirpersonal test-taking abilities. There are people who always wait until the lastminute, and make it much harder than it needs to be. And then there thosewho, not knowing what questions are coming at them, and having noresources to refer to, can freeze. And then there are we rare folks who fitboth those descriptions.[I] Yes, my advanced age must factor into the equation (等式), in partbecause of my inability toaccess the information as quickly. As another returning student at Columbia, Kate Marber, toldme, ―We are learning not only all this information, but essentially how to learn again. Ourfellow students have just come out of high school. A lot has changed since we were last inschool.‖[J] If nothing else, the situation has given my college son and me something to share, When I-class exams asked his opinion on this matter, he responded, ―I like in because the time isalready reserved, as opposed to using my free time at home to work on a test,‖ he responded.It seems to me that a compromise would be receiving the exam questions a day or two inadvance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her finalexam: She encouraged the class not to stress or even study, promising that, ―It is going to be apiece of cake.‖ When the students came in, sharpened pencils in hand, there was not a bluebook in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students' performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult thanthey actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type ofcourse being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the ―first-night‖ effect.

One educator named Dori Roberts decided to do something to change this system. Dori taught high school engineering for 11 years. She noticed there was a real void in quality STEM education at all 27 of the public educational system. She said, “Istarted Engineering For Kids (EFK) after noticing a real lack of math, science and engineering programs to28 my own kids in. ” She decided to start an afterschool program where children 29in STEM-based competitions. The club grew quickly and when it reached 180 members and the kids in the program won several state 30, she decided to devote all her time to cultivating and31it. The global business EFK was born.Dori began operating EFK out of her Virginia home, which she then expanded to32recreation centers. Today, the EFK program33over 144 branches in 32 states within the United States and in 21 countries. Sales have doubled from $5 million in 2014 to $10 million in 2015, with 25 new branches planned for 2016. The EFK website states, “Our nation is not 34 enough engineers.

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Why aren ’tyou curious about what happened?[A ] “You suspended Ray Rice after our video,”a reporter from TMZ challenged National Football League Commissioner Roger Goodell the other day. “Why didn ’tyou have the curiosity to go to the casino ( 赌场 )yourself?” The implication of the question is that a more curious commissioner would have found a way to get the tape.[B] The accusation of incuriosity is one that we hear often, carrying the suggestion that there is something wrong with not wanting to search out the truth. “I have been bothered for a long time about the curious lack of curiosity,”said a Democratic member of the New Jersey legislature back in July, referring to an insufficiently inquiring attitude on the part of an assistant to New Jersey Governor Chris Christie who chose not to ask hard question about the George Washington Bridge traffic scandal.“Isn ’t the mainstream media the least bit curious about what happened?”wrote conservative writer Jennifer Rubin earlier this year, referring to the attack on Americans in Benghazi, Libya.[C] The implication, in each case, is that curiosity is a good thing, and a lack of curiosity is a problem. Are such accusations simply efforts to score political points for one ’s party? Or is there something of particular value about curiosity in and of itself?[D] The journalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Your Future Depends on It, insists that theanswer to that last question is much-overlooked human virtue, losing it.‘Yes ’.Leslie argues that curiosity is a crucial to our success, and that we are[E] We are suffering, he writes, from a “serendipity deficit. ”The word“serendipity”was coined by Horace Walpole in an 1854 letter, from a tale of three princes who “were always making discoveries, by accident, of things they were not in search of.”Leslie worries that the rise of the Internet, among other social and technological changes, has reduced our appetite for aimless adventures. No longer have we the inclination to let ourselves wander through fields of knowledge, ready to be surprised. Instead, we seek only the information we want.[F]Why is this a problem? Because without curiosity we will lose the spirit of innovation and entrepreneurship. We will see unimaginative governments and dying corporations make disastrous decisions. We will lose a vital part of what has made humanity as a whole so successful as a species.[G]Leslie presents considerable evidence for the proposition that the society as a whole is growing less curious. In the U.S and Europe, for example, the rise of the Internet has led to a declining consumption of news from outside the reader’s borders. But not everything is to be blamed on technology. The decline in interest in literary fiction is also one of the causes identified by Leslie. Reading literary fiction, he says, make us more curious.[H]Moreover, in order to be curious, “you have to be aware of a gap in your knowledge in the first place. ”Although Leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we don’tknow, he’s surely right to point out that the problem is growing: “Google can give us the powerful illusion that all questions have definite answers.”[I]Indeed, Google, for which Leslie expresses admiration, is also his frequent whipping body (替罪羊). He quotes Google co-founder Larry Page to the effect that the “perfect search engine”will “understand exactly what I mean and give me back exactly what I want”.Elsewhere in the book, Leslie writes: “Google aims to save you from the thirst of curiosity altogether.”[J]Somewhat nostalgically ( 怀旧地 ), he quotes John MaynardKeynes’s justly famous words of praise to the bookstore: “One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as curiosity dictates, should be an afternoon’s entertainment”.If only! [K]Citing the work of psychologists and cognitive (认知的 ) scientists, Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work. Curiosity, he argues, is the third key factor—and a difficult one to preserve. If not cultivated, it will not survive: “Childhood curiosity is a collaboration between child and adult. The surest way to kill it is to leave it alone”.[L]School education, he warns, is often conducted in a way that makes children incurious. Children of educated and upper-middle-class parentsturn out to be far more curious, even at early ages, than children of working class and lower class families. That lack of curiosity produces a relative lack of knowledge, and the lack of knowledge is difficult if not impossible to compensate for later on[M]Although Leslie ’s book isn ’tabout politics, he doesn ’tentirely shy away from the problem. Political leaders, like leaders of other organizations, should be curious. They should ask questions at crucial moments. There are serious consequence, he warns, in not wanting to know.[N]He presents as an example the failure of the George W. Bush administration to prepare properly for the after-effects of the invasion of Iraq. According to Leslie, those who ridiculed former Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the “unknown unknowns”were mistaken. Rumsfeld’s idea, Leslie writes, “wasn’tabsurd—it was smart.”He adds,“The tragedy is that he didn’t follow his own advice.”[O] All of which brings us back to Goodell and the Christie case and Benghazi. Each critic in those examples is charging, in a different way, that someone in authority is intentionally being curious. I leave it to the reader’s political preference to decide which, if any, charges should stick. But let’s be careful about demanding curiosity about the other side’s weaknessesand remanding determinedly incurious about our own. Weshould be delighted to pursue knowledge for its own sake—even when what we find out is something we didn’tparticularly want to know.36.To be curious, we need to realize first of all that there are manythings we don’tknow.37.According to Leslie, curiosity is essential to one’s success.38.We should feel happy when we pursue knowledge for knowledge’s sake.39.Political leaders’lack of curiosity will result in bad consequences.40.There are often accusations about politicians’and the media’s lackof curiosity to find out the truth41.The less curious a child is, the less knowledge the child may turnout to have.42.It is widely accepted that academic accomplishment lies in both intelligence and diligence.43.Visiting a bookshop as curiosity leads us can be a good way to entertain ourselves.44.Both the rise of the Internet and reduced appetite for literaryfiction contribute to people’s declining curiosity.45.Mankind wouldn’tbe so innovative without curiosity.Section CDirections: There are 2 passages in this section. Each passage is followedby some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a “disease”.On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.“It unties the hands of the pharmaceutical ( 制药的 ) industry so that they can begin treating the disease and not just the side effects,”he said.“Right now, people think of aging as natural and something you can’tcontrol, ”he said. “In academic circles, people take aging research as just an interest area where they can try to develop interventions. Themedical community also takes aging for granted, and can do nothing about it except keep people within a certain health range”.But if aging were recognized as a disease, he said,“It would attract funding and change the way we do health care. What matters is understanding that aging is curable”.“It was always known that the body accumulates damage,”he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions”.Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.“There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,”Hayflick said. “Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years”.46.What do people generally believe about aging?A) It should cause no alarm whatsoever.B) They just cannot do anything about it.C) It should be regarded as a kind of disease.D) They can delay it with advances in science.47.How do many scientists view aging now?A)It might be prevented and treated.B)It can be as risky as heart disease.C)It results from a vitamin deficiency.D)It is an irreversible biological process.48.What does Alex Zhavoronkov think of “describing aging as a disease”?A) It will prompt people to take aging more seriously.B) It will greatly help reduce the side effects of aging.C) It will free pharmacists from the conventional beliefs about aging. D) It will motivate doctors and pharmacists to find ways to treat aging.49.What do we learn about the medical community?A)They now have a strong interest in research on aging.B)They differ from the academic circles in their view on aging.C)They can contribute to people’s health only to a limited extent.D)They have ways to intervene in people’s aging process.50.What does professor Leonard Hayflick believe?A) The human lifespan cannot be prolonged.B) Aging is hardly separable from disease.C) Few people live up to the age of 92.D) Heart disease is the major cause of aging.Passage TwoQuestions 51 to 55 are based on the following passage.Female applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts. Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring指(导 ), and have better odds of being hired. Studies show they’re also perceived as more competent than women in STEM (Science, Technology, Engineering, and Mathematics) fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too.“Say, you know, this is the best student I’ve ever had,”says Kuheli Dutt, a social scientist and diversity officer at Columbia University ’s Lamont campus. “Compare those excellent letters with a merely good letter: ‘The candidate was productive, or intelligent, or a solid scientist or something that’s clearly solid praise,’but nothing that singles out the candidate as exceptional or one of a kind”.Dutt and her colleagues studied more than 1,200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared with their male counterparts. That includesletters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt says they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than outstanding letters of recommendation.“We’re not trying to assign blame or criticize anyone or call anyone conscious sexist. Rather, the point is to use the results of this study to open up meaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level.”Which may lead to some recommendations for the letter writers themselves.51.What do we learn about applicants to postdoctoral positions in geosciences?A) There are many more men applying than women.B) Chances for women to get the positions are scare.C) More males than females are likely to get outstanding letters of recommendation.D) Male applicants have more interest in these positions than their female counterparts.52.What do studies about men and women in scientific research show?A)Women engaged in postdoctoral work are quickly catching up.B)Fewer women are applying for postdoctoral positions due to gender bias.C)Men are believed to be better able to excel in STEM disciplines.D)Women who are keenly interested in STEM fields are often exceptional.53. What do the studies find about the recommendation letters for women applicants?A)They are hardly ever supported by concrete examples.B)They contain nothing that distinguishes the applicants.C)They provide objective information without exaggeration.D)They are often filled with praise for exceptional applicants.54. What did Dutt and her colleagues do with the more than 1,200 letters of recommendation?A)They asked unbiased scholars to evaluate them.B)They invited women professionals to edit them.C)They assigned them randomly to reviewers.D)They deleted all information about gender.55. What does Dutt aim to do with her study?A)Raise recommendation writers’awareness of gender bias in their letters.B)Open up fresh avenues for women post-doctors to join in researchC)Alert women researchers to all types of gender bias in the STEM disciplines.D)Start a public discussion on how to raise women’s status in academic circles.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passagefrom Chinese into English.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Readthe passage through carefully before making your choices. Each choice in the bank isidentified by a letter. Please mark the corresponding letter for each item on AnswerSheet 2 with a single line through the centre. You may not use any of the words in thebank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some ___26___ skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban __27__, but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the _28_of your index finger, pigeons have a very impressive___29___ memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often ___30___with spreading disease rather than___31___ it, but this long-tailed animal is highly___32___. Inside a rat's nose are up to 1,000 different types of olfactory receptors (嗅觉感受器), whereas humans only have 100 to 200 types. This gives rats the ability todetect___33___smells. As a result, some rats are being put to work to detect TB(肺结核). When the rats detect the smell, they stop and rub their legs to ___34___ a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to ___35___, but for a rat it takes less than 20 minutes.

Identify theparagraph from which the information is derived. You may choose a paragraph morethan once. Each paragraph is marked with a letter. Answer the questions by markingthe corresponding letter on Answer Sheet 2.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A] I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B] Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C] As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. “That way they socialize over history outside the class, which wouldn’t happen withou t the pressure of anin-class exam,” he explained, “Furthermore, in-class exams force students to learn how to perform under pressure, and essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled “Introduction To Congress.” Some colleges have what they call an “honor code,” though if you are smart enough to get into these sch ools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.[E] Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school’s professors to refrain from take-hone exams. “Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,” she told me. “Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”[F] Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches “History of Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “In my field, it’s not what you know—it’s what you know how to find out,” says Koch. “There is way too much information, and more c oming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.[G] Students’ test-form preferences vary, too, often depending on the subject and course difficulty. “I pref er take-home essays because it is then really about the writing, so you have time to edit and do more research,” says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment whe n the time is up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. “If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze.”[H] How students ultimately handle stress may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.[I] Yes, my advanced age must factor into the equation (等式), in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, “We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school.”[J] If nothing else, the situation has given my college son and me something to share, When Iasked his opinion on this matter, he responded, “I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test,” he responded.It se ems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, “It is going to beapiece of cake.” When the students came in, sharpened pencils in hand, there was not a bluebook in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students' performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult than they actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type of course being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) andD). You should decide on the best choice and mark the corresponding letter onAnswer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night” effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participantsslept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people. C) What circumstances may trigger it.B) What role it has played in evolution. D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphinsD) She conducted studies on birds’ and dolphins’ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants’ brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants’ adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants.50. What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It’s time to reevaluate how women handle conflict at work. Being overworked orover-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling “very tired” or “exhausted”, according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able to do it all volunteer for school parties or cook delicious meals-and so their answer to any request is often “Yes, I can.”Women struggle to say “no” in the workplace for similar reasons, including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's heath as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there’s a problem that needs to be addressed immediately, resulting in a dispute over should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem-even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely – including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51. What does the author say is the problem with women?A) They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A) They struggle to satisfy the demands of both work and home.B) They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D) They are obliged to take up too many responsibilities.53. What may hinder the future prospects of career women?A) Their unwillingness to say “no”.B) Their desire to be considered powerful.C) An underestimate of their own ability.D) A lack of courage to face challenges.54. Men and woman differ in their approach to resolving workplace conflicts in that______.A) women tend to be easily satisfiedB) men are generally more persuasiveC) men tend to put their personal interests firstD) women are much more ready to compromise55. What is important to a good leader?A) A dominant personality. C) The courage to admit failureB) The ability to delegate. D) A strong sense of responsibility.Part ⅣTranslation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

News 2： Last week, France announced that the country will pave 621 miles of road with solar panels over the next five years, with the goal of providing cheap, renewable energy to five million people. Called “the Wattway,” the roads will be built through joint efforts with the French road-building company Colas and the National Institute of Solar Energy. The company spent the last five years developing solar panels that are only about a quarter of an inch thick and are strong enough to stand up to heavy highway traffic without breaking or making the roadsmore slippery. The panels are also designed so that they can be installed directly on top of existing roadways, making them relatively cheap and easy to install. France isn’t the first country to kick around the idea of paving its roads with solar panels. In November 2015, the Netherlands completed a 229-foot-long bike path paved with solar panels as a test for future projects. However, this is the first time a panel has been designed to be laid directly on top of existing roads and the first project to install the panels on public highways. Questions 3 and 4 are based on the news report you have just heard. Q3: What was France's purpose of constructing the Wattway? A)Finding cheaper ways of highway construction. B)Generating electric power for passing vehicles. C)Providing clean energy to five million people. D)Testing the efficiency of the new solar panel. 答案：C) Providing clean energy to five million people. Q4: What is special about the solar panels used in the Wattway? A)They can stand the wear and tear of natural elements. B)They can be laid right on top of existing highways. C)They can only about half an inch thick. D)They are made from cheap materials. 答案：B) They can be laid right on top of existing highways. News 3： Lions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. Continuous fighting in the region has made surveys difficult. But scientists released a report Monday documenting, with hard evidence, the discovery of "lost lions." A team with Oxford University’s Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in the National Park in northwest Ethiopia, on the Ethiopia-Sudan border. The researchers set out six camera traps capturing images of lions, and they identified lion tracks. The scientists concluded that lions are also likely to live in the neighbouring National Park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a "possible range" for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence. Questions 5 and 7 are based on the news report you have just heard. Q5: What has made it difficult to survey lions in remote parts in Sudan and Ethiopia? A)Endless fighting in the region. B)The hazards from the desert. C)Inadequate funding for research. D)The lack of clues about the species. 答案：A) Endless fighting in the region. Q6: What was the main purpose of the research? A)To observe the wildlife in the two national parks. B)To identify the reasons for the lions’ disappearance. C)To study the habitat of lions in Sudan and Ethiopia. D)To find evidence of the existence of the “lost lions”. 答案：D) To find evidence of the existence of the "lost lions". Q7: What did the researchers find in the National Park? A) Lions walking. C) Some camping facilities. B) Lion’s tracks. D) Traps set by local hunters. 答案：B) Lions' tracks. Section B Directions: In this section, you will hear two long conversations. At the end of each conversation, you will hear four questions. Both the conversation and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C) and D). Then mark the corresponding letter on Answer sheet 1 with a single line through the centre. Passage 1 M: I bet you're looking forward to the end of this month. Are you? W: Yes, I am. How did you know? M: David told me you had a special birthday coming up. W: Oh…yeah that's right. This year will be my golden birthday. M: What does that mean? I've never heard of a golden birthday. W: I've actually just learnt this concept myself. Fortunately, just in time to celebrate. A golden or lucky birthday is when one turns the age of their birth date. So, for example, my sister's birthday is December 9th and her golden birthday would have been the year she turned nine years old. Come to think of it, my parents did throw her a surprise party that year. M: Interesting. Too bad I missed mine. My golden birthday would've been four years ago. I assume you got big plans then. W: Actually yes. My husband is planning a surprise holiday for the two of us next week. I have no idea what he's got in mind, but I'm excited to find out. Has he mentioned anything to you? M: He might have. W: Anything you'd like to share? I'm dying to know what kind of trip he has planned on where we're going. M: You know nothing at all? W: Not a clue. Hard to imagine, isn’t it? Though I must say I think he's been having even more fun keeping the secret from me in the past few weeks. M: I'm sure both of you will have a fantastic time. Happy golden birthday! I can't wait to hear all about it when you get back. Questions 8 to 11 are based on the conversation you have just heard. Q8. What is the woman looking forward to? A) Her ‘lucky birthday’ C) Her wedding anniversary. B) A call from her dad. D) A special gift from the man. 答案：A) Her 'lucky birthday'. Q9. What did the woman's parents do on her sister's lucky birthday? A) Gave her a big model plane. C) Took her on a trip overseas. B) Bought her a gold necklace. D) Threw her a surprise party. 答案：D) Threw her a surprise party. Q10. What is the woman eager to find out about? A) The gift her husband has bought. B) The trip her husband has planned. C) What has been troubling her husband. D) What her husband and the man are up to. 答案：B) The trip her husband has planned. Q11. What does the man say at the end of the conversation? A) He will be glad to be a guide for the couple’s holiday trip. B) He will tell the woman the secret if her husband agrees. C) He is eager to learn how the couple’s holiday turns out. D) He wants to find out about the couple’s holiday plan. 答案： C) He is eager to learn how the couple's holiday turns out. Passage 2 W: Mr. Green, what do you think makes a successful negotiator? M: Well, that’s hard to define. But I think successful negotiators have several things in common. They are always polite and rational people. They are firm but flexible. They can recognize power and know how to use it. They are sensitive to the dynamics of the negotiation. The way of rises and falls and how it may change direction. They project the image of confidence, and perhaps most importantly, they know when to stop. W: And, what about an unsuccessful negotiator? M: Well, this is probably all of us when we start out. We are probably immature and over-trusting. Too emotional or aggressive. We are unsure of ourselves and we want to be liked by everyone. Good negotiators learn fast. Poor negotiators remain like that and go on losing negotiations. W: In your opinion, can the skills of negotiation be taught? M: Well, you can teach someone how to prepare for a negotiation. There are perhaps six stages in every negotiation. Get to know the other side. State your goals. Start the process. Clarify areas of disagreement or conflict. Reassess your position. Making acceptable compromises. And finally, reach some agreement in principle. These stages can be studied. And strategies to be used in each can be planned beforehand. But I think, the really successful negotiator is probably born with six sense about responding appropriately to the situation at hand. W: The artistic sense you’ve just described? M: Yes. That’s right. Questions 12 to 15 are based on the conversation you have just heard. Q12: What does the man say about good negotiators? A) They are sensitive to the dynamics of a negotiation. B) They see the importance of making compromises. C) They know when to adopt a tough attitude. D) They take the rival’s attitude into account. 答案：A) They are sensitive to the dynamics of a negotiation. Q13: What does the man say may be the most important thing to a successful negotiator? A) They know how to adapt. C) They know when to make compromises. B) They know when to stop. D) They know how to control their emotion. 答案：B) They know when to stop. Q14: How is a good negotiator different from a poor one? A) They are patient. C) They learn quickly. B) They are good at expression. D) They uphold their principles. 答案： C) They learn quickly. Q15: What is the first stage of negotiation according to the man? A) Make clear one’s intentions. C) Formulate one’s strategy. B) Clarify items of negotiation. D) Get to know the other side. 答案：D) Get to know the other side. Section C Directions: In this section, you will hear three passages. At the end of each passage, you will hear three or four questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C), D). Then mark the corresponding letter on Answer Sheet 1 with a single line through the centre. Passage 1 Some people wonder why countries spend millions of dollars on space projects. They want to know how space research helps people on Earth. Actually space technology helps people on Earth every day. This is called "spin-off technology." Spin-off technology is space technology that is now used on Earth. In early space programs, such as the Apollo missions of the 1960s and 1970s, and in the Space Shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space. We now use some of these objects every day. For example, we have Quartz c r y s t a l c l o c k s a n d w a t c h e s a c c u r a t e t o w i t h i n o n e m i n u t e a y e a r .

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some 26 skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban 27 , but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the 28 of your index finger, pigeons have a very impressive 29__ memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors （嗅觉感受器）, whereas humans only have 100to 200 types. This gives rats the ability to detect __33 smells. As a result, some rats are being put to work to detect TB（肺结核）. When the rats detectthe smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate— the rats are able to find more TB infections and, therefore, save more lives.A)associated I) slightB)examine J) specifyC)indicate K) superiorD)nuisance L) suspiciousE)peak M) tipF)preventing N) treatedG)prohibiting O) visualH)sensitiveSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in oneof the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraphis marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A]I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B]Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C]As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. ―That way they socialize over history outside the class, which wouldnhappen without the pressure of an inclass- exam,‖ he explained,―Furthermore, in-class exams force students to learn how to perform underpressure, and essential work skill.‖[D]He also says there is less chance of cheating with the in-class variety.In 2012, 125 students at Harvard were caught up in a scandal when it wasdiscovered they had cheated on a take-home exam for a class entitled― Introduction To Congress.‖ Some colleges have what theyonorcall an―code, ‖ though if you are smart enough to get into theseschools, you areeither smart enough to get around any codes or hopefully, too ethical toconsider doing so. As I sat blocked and clueless for two solid days, Imomentarily wondered if I couldn just call‘t anexpert on the subject matterwhich I was tackling, or someone who took the class previously, to get megoing.[E] Following the Harvard scandal, Mary Miller, the former dean ofstudents at Yale, made an impassioned appeal to her school ofessors to ‘ s prrefrain from take- hone exams. ―Students risk health and well being, as wellas performance in other end-of-term work, when faculty offers take-homeexams without clear, time-limited boundaries,‖ she told me.―Research now shows that regular quizzes, short essays, and other assignments over thecourse of a term better enhance learning and retention.‖[F]Most college professors agree the kind of exam they choose largelydepends on the subject. A quantitative-based one, for example, is unlikely tobe sent home, where one could ask their older brothers and sisters to help.Vocational-type classes, such as computer science or journalism, on theother hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches ―History of Broadcast Journalism ‖ at Montgomery Community College in Rockville, Maryland,points out that reporting is about investigation rather than the memorizationof minute details. ― In my field, it ‘ s not what you know —it ‘ s what y how to find out, ‖ says Koch. ―There is way too much information, and more coming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.[G] Students‘ -testform preferences vary, too, often depending on thesubject and course difficulty.―-homIpr e f e rssaystake because it is thenreally about the writing, so you have time to edit and do more research,says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor.Francesca Haass, a senior at Middlebury, says,-class― Ionesfind theare inmore stressful in the short term, but there is immediate relief as you swallowinformation like mad, and then you get to forget it all. Take-homes requirethoughtful engagement which can lead to longer term stress as there is nevera moment when the time is up.‖ Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers takehomes-true exams.―If youunderstand the material and have the ability to articulate 说(出 ) yourthoughts, they should be a breeze.‖[H] How students ultimately handle stress may depend on theirpersonal test-taking abilities. There are people who always wait until the lastminute, and make it much harder than it needs to be. And then there thosewho, not knowing what questions are coming at them, and having noresources to refer to, can freeze. And then there are we rare folks who fitboth those descriptions.[I] Yes, my advanced age must factor into the equation (等式 ), in partbecause of my inability toaccess the information as quickly. As another returning studentat Columbia, Kate Marber, toldme, ―We are learning not only all this information, but essentially how to learn again. Ourfellow students have just come out of high school. A lot has changed since we were last inschool. ‖[J]If nothing else, the situation has given my college son and me something to share, When I-class―I likeexamsin asked his opinion on this matter, he responded,because the time isalready reserved, as opposed to using my free time at home to work on a test, ‖ he responded.It seems to me that a compromise would be receiving theexam questions a day or two inadvance, and then doing the actual test in class the ticking clock overhead.[K]Better yet, how about what one Hunter College professor reportedly did recently for her finalexam: She encouraged the class not to stress or even study, promising that, ― It is going to be apiece of cak e. ‖ When the students came in, sharpenedilspencinhand, there was not a bluebook in sight. Rather, they saw a large chocolate cake and theyeach were given a slice.36.Elderly students find it hard to keep up with the rapid changesin education.37.Some believe take-home exams may affect students' performance in other courses.38.Certain professors believe in-class exams are ultimatelymore helpful to students.39.In-class exams are believed to discourage cheating in exams.40.The author was happy to learn she could do some exams at home.41.Students who put off their work until the last moment often findthe exams more difficult thanthey actually are.42.Different students may prefer different types of exams.43.Most professors agree whether to give an in-class or a take-home exam depends on type ofcourse being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide onthe best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the - night ‖ ―effectfirst. If a person stays in the same room t he following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put halfof their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者 ). This led herto wonderif people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university ‘ s Department of PsychogicaloSciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, asexpected, the participants slept less well on their first night than they did ontheir second, taking more than twice as long to fall asleep and sleeping lessoverall. During deep sleep, the participants ‘ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the lefthemispheres (半球) of their brains did not sleep nearly as deeply as theirright hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran theexperiment while presenting the sleeping participants with a mix of regularlytimed beeps (蜂鸣声 ) of the same tone and irregular beeps of adifferent tone during the night. She worked out that, if the left hemispherewas staying alert to keep guard in a strange environment, then it would reactto the irregular beeps by stirring people from sleep andwould ignore theregularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A)To what extent it can trouble people. C) What circumstances maytrigger it.B)What role it has played in evolution. D) In what way it canbe beneficial.47.What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphinsD) She conducted studies on birds‘ and dolphins‘ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A)She monitored the brain activity of participants sleeping in a new environment.B)She recruited 35 participants from her Department ofPsychological Sciences.C) She studied the differences between the two sides of participants‘brains.D)She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A)She analyzed the negative effect of irregular tones on brains.B)She recorded participants‘ adaptation to changed environment.C)She exposed her participants to two different stimuli.D)She compared the responses of different participants.50.What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B)They tended to perceive irregular beeps as a threat.C)They felt sleepy when exposed to regular beeps.D)They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It ‘s time to reevaluatehow women handle conflict at work. Being overworked or over-committed at home and on the job will not get youwhere you want to be in life. It will only slow you down and hinderyour career goals.Did you know women are more likely than men to feel exhausted?―very Nearly twice as many women than men ages 1844- reported feelingtired ‖ or ― exhausted ‖ , according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no."

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Readthe passage through carefully before making your choices. Each choice in the bank isidentified by a letter. Please mark the corresponding letter for each item on AnswerSheet 2 with a single line through the centre. You may not use any of the words in thebank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some ___26___ skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban __27__, but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having a brain no bigger than the _28_of your index finger, pigeons have a very impressive___29___ memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often ___30___with spreading disease rather than___31___ it, but this long-tailed animal is highly___32___. Inside a rat's nose are up to 1,000 different types of olfactory receptors (嗅觉感受器), whereas humans only have 100 to 200 types. This gives rats the ability todetect___33___smells. As a result, some rats are being put to work to detect TB(肺结核). When the rats detect the smell, they stop and rub their legs to ___34___ a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to ___35___, but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate — the rats are able to find more TB infections and, therefore, save more lives.Section BDirections: In this section, you are going to read a passage with ten statements attached to it.Each statement contains information given in one of the paragraphs. Identify theparagraph from which the information is derived. You may choose a paragraph morethan once. Each paragraph is marked with a letter. Answer the questions by markingthe corresponding letter on Answer Sheet 2.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.[A] I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.[B] Since there is no way for me to avoid exams, I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. To say I had lost the thread is putting it mildly.[C] As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I did some of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S. presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. “That way they socialize over history outside the class, which wouldn’t happen withou t the pressure of anin-class exam,” he explained, “Furthermore, in-class exams force students to learn how to perform under pressure, and essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled “Introduction To Congress.” Some colleges have what they call an “honor code,” though if you are smart enough to get into these sch ools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn’t just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me going.[E] Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school’s professors to refrain from take-hone exams. “Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries,” she told me. “Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention.”[F] Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-based one, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help. Vocational-type classes, such as computer science or journalism, on the other hand, are often more research-oriented and lend themselves to take-home testing. Chris Koch, who teaches “History of Broadcast Journalism” at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. “In my field, it’s not what you know—it’s what you know how to find out,” says Koch. “There is way too much information, and more c oming all the time, for anyone to remember. I want my students to search out the answers to questions by using all the resources available to them.[G] Students’ test-form preferences vary, too, often depending on the subject and course difficulty. “I pref er take-home essays because it is then really about the writing, so you have time to edit and do more research,” says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, “I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment whe n the time is up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. “If you understand the material and have the ability to articulate (说出) your thoughts, they should be a breeze.”[H] How students ultimately handle stress may depend on their personal test-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there those who, not knowing what questions are coming at them, and having no resources to refer to, can freeze. And then there are we rare folks who fit both those descriptions.[I] Yes, my advanced age must factor into the equation (等式), in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, “We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school.”[J] If nothing else, the situation has given my college son and me something to share, When Iasked his opinion on this matter, he responded, “I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test,” he responded.It se ems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, “It is going to beapiece of cake.” When the students came in, sharpened pencils in hand, there was not a bluebook in sight. Rather, they saw a large chocolate cake and they each were given a slice.36. Elderly students find it hard to keep up with the rapid changes in education.37. Some believe take-home exams may affect students' performance in other courses.38. Certain professors believe in-class exams are ultimately more helpful to students.39. In-class exams are believed to discourage cheating in exams.40. The author was happy to learn she could do some exams at home.41. Students who put off their work until the last moment often find the exams more difficult than they actually are.42. Different students may prefer different types of exams.43. Most professors agree whether to give an in-class or a take-home exam depends on type of course being taught.44. The author dropped out of college some forty years ago.45. Some students think take-home exams will eat up their free time.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) andD). You should decide on the best choice and mark the corresponding letter onAnswer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night” effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university’s Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participantsslept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants’ brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people. C) What circumstances may trigger it.B) What role it has played in evolution. D) In what way it can be beneficial.47. What do we learn about Dr. Yuka Sasaki doing her research?A) She found birds and dolphins remain alert while asleep.B) She found birds and dolphins sleep in much the same way.C) She got some idea from previous studies on birds and dolphinsD) She conducted studies on birds’ and dolphins’ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.B) She recruited 35 participants from her Department of Psychological Sciences.C) She studied the differences between the two sides of participants’ brains.D) She tested her findings about birds and dolphins on human subjects.49. What did Dr. Sasaki do when re-running her experiment?A) She analyzed the negative effect of irregular tones on brains.B) She recorded participants’ adaptation to changed environment.C) She exposed her participants to two different stimuli.D) She compared the responses of different participants.50. What did Dr. Sasaki find about the participants in her experiment?A) They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D) They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It’s time to reevaluate how women handle conflict at work. Being overworked orover-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling “very tired” or “exhausted”, according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able to do it all volunteer for school parties or cook delicious meals-and so their answer to any request is often “Yes, I can.”Women struggle to say “no” in the workplace for similar reasons, including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's heath as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example, there’s a problem that needs to be addressed immediately, resulting in a dispute over should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem-even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely – including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51. What does the author say is the problem with women?A) They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A) They struggle to satisfy the demands of both work and home.B) They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D) They are obliged to take up too many responsibilities.53. What may hinder the future prospects of career women?A) Their unwillingness to say “no”.B) Their desire to be considered powerful.C) An underestimate of their own ability.D) A lack of courage to face challenges.54. Men and woman differ in their approach to resolving workplace conflicts in that______.A) women tend to be easily satisfiedB) men are generally more persuasiveC) men tend to put their personal interests firstD) women are much more ready to compromise55. What is important to a good leader?A) A dominant personality. C) The courage to admit failureB) The ability to delegate.

You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.We all know there exists a great void（空白）in the public educational system when it comes to 26 to STEM（Science, Technology, Engineering and Mathematics）courses. One educator named Dori Roberts decided to do something to change this system. Dori taught high school engineering for 11 years. She noticed there was a real void in quality STEM education at all 27 of the public educational system. She said, “I started Engineering For Kids (EFK)after noticing a real lack of math, science and engineering programs to 28 my own kids in”She decided to start an afterschool program where children 29 in STEM-based competitions. The club grew quickly and when it reached 180 members and the kids in the program won several state 30 , she decided to devote all her time to cultivating and 31 it. The global business EFK was born.Dori began operating EFK out of her Virginia home, which she then expanded to 32 recreation centers. Today, the EFK program 33 over 144 branches in 32 states within the United States and in 21 countries. Sales have doubled from $5 million in 2014 to $10 million in 2015,with 25 new branches planned for 2016. T he EFK website states, “Our nation is not 34 enough engineers. Our philosophy is to inspire kids at a young age to understand that engineering is a great 35 .”Section BDirections:In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Why aren't you curious about what happened?A) “You suspended Ray R ice after our video,” a reporter from TMZ challenged National Football League Commissioner Roger G oodell the other day. “W hy didn’t you have the cur iosity to go to the casino (赌场) yourself?” The implication of the question is that a more curious. commissioner would have found a way to get the tape.B) The accusation of incuriosity is one that we hear often, carrying the suggestion that there is something wrong with not wanting to search out the truth. “I have been bothered for a long time about the curious lack of curiosity,” said a Democratic member of the New Jersey legislature back in July, referring to an insufficiently inquiring attitude on the part of an assistant to New Jersey Governor Chris Christie who chose not to ask hard questions about the George Washington Bridge traffic scandal. “Isn’t the mainstream media the least bit curious about what happened?” wrote conservative writer Jennifer Rubin earlier this year, referring to the attack on Americans in Benghazi, Libya.C) The implication, in each case, is that curiosity is a good thing, and a lack of curiosity is a problem. Are such accusations simply efforts to score political points for one's party? Or is there something of particular value about curiosity in and of itself?D) The journalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Your Fatter Depends on It, insists that the answer to that last question is ‘Yes.’ Leslie argues that curiosity is a much-overlooked human virtue, crucial to our success, and that we are losing it.E)We are suffering, he writes, from a “serendipity deficit.” The word “serendipity” was coined by Horace Walpole in an 1854 letter, from a tale of three princes who “were always making discoveries, by accident, of things they were not in search of,” Leslie worries that the rise of the Internet, among other social and technological changes, has reduced our appetite for aimless adventures. No longer have we the inclination to let ourselves wander through fields of know ledges, ready to be surprised. Instead, we seek only the information we want.F) Why is this a problem? Because without curiosity we will lose the spirit of innovation and entrepreneurship. We will see unimaginative governments and dying corporations make disastrous decisions. We will lose a vital part of what has made humanity as a whole so successful as a species.G) Leslie presents considerable evidence for the proposition that the society as a whole is growing less curious. In the U.S. and Europe, for example, the rise of the I nternet has led to a declining consumption of news from outside the reader’s borders .But not everything is to be blamed on technology. The decline in interest in literary fiction is also one of the causes identified by Leslie. Reading literary fiction, he says ,make us more curious.H)Moreover, in order to be curious, “you have to be aware of a gap in your knowledge in the first place.” Although Leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we don’t know, he’s surely right to point out that the problem is growing: “Google can give us the powerful illusion that all questions have definite answers.”I）Indeed, Google, for which Leslie expresses admiration, is also his frequent whipping body(替罪羊). He quotes Google co-founder Larry Page to the effect that the “perfect search engine” will“understand exactly what I mean and give me back exactly what I want.” Elsewhere in the book, Leslie writes: “G oogle aims to save you from the thirst of curiosity altogether.”J) Somewhat nostalgically(怀旧地), he quotes John Maynard K eynes’s justly famous words of praise to the bookstore: “One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as curiosity dictates, should be an afternoons entertainment.” If only!K) Citing the work of psychologists and cognitive( 认知的)scientists, Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work. Curiosity, he argues, is the third key factor--and a difficult one to preserve. If not cultivated, it will not survive: “Childhood curiosity is a collaboration between child and adult. The surest way to kill it is to leave it alone.”L) School education, he warns, is often conducted in a way that makes children incurious. Children of educated and upper-middle-class parents turn out to be far more curious, even at early ages, than children of working class and lower class families. That lack of curiosity produces a relative lack of knowledge, and the lack of knowledge is difficult if not impossible to compensate for later on.M）Although L eslie’s book isn’t about politics, he doesn’t entirely shy away from the problem. Political leaders, like leader of other organizations, should be curious. They should ask questions at crucial moments . There serious consequences, he warns, in not wanting to know.N) He presents as an example the failure of the George W. Bush administration to prepare properly for the after-effects of the invasion of Iraq. According to Leslie, those who ridiculed former. Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the “unknown unknowns” were mistaken. R umsfeld’s idea, L eslie writes, “wasn’t absurd- it was smart.”H e adds, “T he tragedy is that he didn’t follow his own advice.”O) All of which brings us back to Goodell and the Christie case and Benghazi. Each critic in those examples is charging, in a different way, that someone in authority is intentionally being incurious. I leave it to the reader's political preference to decide which, if any, charges should stick. But let’s be careful about demanding curiosity about the other side’s weaknesses and remaining determinedly incurious about our own. We should be delighted to pursue knowledge for its own sake--even when what we find out is something we didn’t particularly want to know.36. T o be curious, we need to realize first of all that there are many things we don’t know.37. According to L eslie, curiosity is essential to one’s success.38. W e should feel happy when we pursue knowledge for knowledge’s sake.39. Political leader s’ lack of curiosity will result in bad consequences.40. T here are often accusations about politicians' and the media’s lack of curiosity to find out the truth.41. The less curious a child is, the less knowledge the child may turn out to have.42. It is widely accepted that academic accomplishment lies in both intelligence and diligence.43. Visiting a bookshop as curiosity leads us can be a good way to entertain ourselves.44. Both the rise of the Internet and reduced appetite for literary fiction contri bute to people’s declining curiosity.45. M ankind wouldn’t be so innovative without cur iosity.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a “disease.”On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments.“It unties the hands of the pharmaceutical(制药的)industry so that they can begin treating the disease and not just the side effects,” he said.“Right now, people think of aging as natural and something you can’t control,” he said. “In academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.”But if aging were recognized as a disease, he said, “It would attract funding and change the way we do health care. What matters is understanding that aging is curable.”“I t was always known that the body accumulates damage,” he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions.”Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them.“There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,” Hayflick said. “Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years.”46. What do people generally believe about aging?A) It should cause no alarm whatsoever.B)They just cannot do anything about it.C) It should be regarded as a kind of disease.D)They can delay it with advances in science.47. How do many scientists view aging now?A) It might be prevented and treated.B) It can be as risky as heart disease.C) It results from a vitamin deficiency.D)It is an irreversible biological process.48. What does Alex Zhavoronkov think of “describing aging as a dis e ase”?A) It will prompt people to take aging more seriously.B) It will greatly help reduce the side effects of aging.C) It will free pharmacists from the conventional beliefs about aging.D)It will motivate doctors and pharmacists to find ways to treat aging.49. What do we learn about the medical community?A) They now have a strong interest in research on aging.B) They differ from the academic circles in their view on aging.C)They can contribute to people’s health only to a limited extent.D) T hey have ways to intervene in people’s aging process.50. What does Professor Leonard Hayflick believe?A)The human lifespan cannot be prolonged.B)Aging is hardly separable from disease.C) Few people can live up to the age of 92.D) Heart disease is the major cause of aging.Passage TwoQuestions 51 to 55 are based on the following passageFemale applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts. Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring (指导), and have better odds of being hired. Studies show they’re also perceived as more competent than women in STEM(Science, Technology, Engineering, and Mathematics) fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too.“Say, you know, this is the best student I’ve ever had,” says Kuheli Dutt, a social scientist and diversity officer at Columbia U niversity’s Lamont campus. “C ompare those excellent letters with a merely good letter: ‘The candidate was productive, or intelligent, or a solid scientist or something that’s clearly solid praise,’ but nothing that singles out the candidate as exceptional o r one of a kind.”Dutt and her colleagues studied more than 1,200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared with their male counterparts. That includes letters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt says they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than outstanding letters of recommendation.“W e’re not tryin g to assign blame or criticize anyone or call anyone conscious sexist. Rather, the point is to use the results of this study to open up meaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level.” Which may lead to some recommendations for the letter writers themselves.51. What do we learn about applicants to postdoctoral positions in geosciences?A) There are many more men applying than women.B)Chances for women to get the positions are scare.C) More males than females are likely to get outstanding letters of recommendation.D) Male applicants have more interest in these positions than their female counterparts.52. What do studies about men and women in scientific research show?A) Women engaged in postdoctoral work are quickly catching up.B) Fewer women are applying for postdoctoral positions due to gender bias.C) Men are believed to be better able to excel in STEM disciplines.D)Women who are keenly interested in STEM fields are often exceptional.53.What do the studies find about the recommendation letters for women applicants?A)They are hardly ever supported by concrete examples.B)They contain nothing that distinguishes the applicants.C) They provide objective information without exaggerate.D)They are often filled with praise for exceptional applicants.54.What did Dutt and her colleagues do with the more than 1, 200 letters of recommendation?A)They asked unbiased scholars to evaluate them.B)They invited women professionals to edit them.C)Them assigned them randomly to reviewers.D) They deleted all information about gender.55. What does Dutt aim to do with her study?A) R aise recommendation writers’ awareness of gender bias in their letters.B)Open up fresh avenues for women post-doctors to join in research work.C) Alert women researchers to all types of gender bias in the STEM disciplines.D) S tart a public discussion on how to raise women’s status in academic circles.Part ⅣTranslation (30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.
