Reading ComprehensionDirections: There are 3 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 choicePassage OneUniversity’s Boot Camp Gives Freshmen Fighting ChancRENO, Nev. -- Welcome to boot camp, you maggots.Stand up straight, suck in that gut and recite the periodic table.What did you say? I can’t hear you! Drop and give me 20.When the University of Nevada, Reno holds its first academic boot camp Aug. 16-20, there won't be any snarling drill instructors ordering freshmen to scrub the latrines with toothbrushes, but it won‘t be easy, either.They will spend five days, from 8 a.m. to 9 p.m., attending classes, working in study groups and taking exams.Just as basic training prepares soldiers for combat, the goal of UNR‘s new boot camp, called Biofit, is to help freshmen majoring in certain scientific fields improve their chances of surviving that fragile first semester of college.―S tudents of all levels of preparation come here, and some of them struggle that first semester,‖said Jeff Thompson, dean of UNR‘s College of Science. ―And studies show that if students struggle that first semester, it‘s very hard for them to overcome.‖Struggling students also are at risk of dropping out, and UNR is on a mission to improve its graduation rate.Last year, slightly more than half of the freshmen who entered UNR in 2006 graduated.The graduation rate in 2012 for UNR students who earned a diploma in six years was 54 percent. That's 2 points below the national six-year graduation rate of 56 percent.Another hopeful indicator is UNR‘s retention rate: 79 percent of the freshmen who came on campus in 2011 were still enrolled when the next fall semester began.Attending the boot camp is voluntary, and during its first year, enrollment will be limited to freshmen who plan to major in biology or neuroscience.―It‘s a test run with no risk to them,‖ Thompson said. ―They have the opportunity to make adjust ments before they get a poor grade that first semester that‘s hard to recover from. That‘s really what we‘re trying to address.‖The students will live in the same residence hall and have to pay $200, which will cover food, room and program materials.UNR joins a growing number of campuses that offer this type of experience to help freshman successfully make the transition from high school to college.Louisiana State University held the first weeklong boot camp in 2005 for new freshmen biology majors at its College of Science, where Kevin Carman was the dean at the time.Carman, who became UNR‘s new provost in February, made starting a boot camp at UNR one of his top priorities.Thompson said LSU‘s boot camp has increased student graduation rates for new freshmen by 50 percent.―That is very significant,‖ he said.He credits that improvement to the way boot camp exposes freshmen to the tougher academic requirements of higher education before they start their first semester.―The point of boot camp is that college is very different, but most students don‘t really understand that,‖ Thompson said.They can hear that message repeated by UNR recruiters, high school counselors and their parents, but the boot camp experience drives it home, he said.―We try to compre ss into a fairly short time what it is like to be a university student,‖ Thompson said.The students will attend several classes each day, take exams and get feedback on how they did.Although the first Biofit boot camp will be open only to biology and neuroscience majors, Thompson wants to offer it next year to all of the incoming freshman in the College of Science.―Provost Carman eventually wants to expand this across as much of the university as we can,‖ Thompson said.Other universities have boot camps for students majoring in theater, engineering and business as well as for disabled veterans and high school graduates who are smart but at-risk because of bad study habits.Christina Cho, UNR‘s director of advising, recruitment and retention for the College of Science, said the college is recruiting undergraduates majoring in biology and neuroscience to serve as mentors for the boot camp students.Biology majors Brandy Reynolds and Chris Gomez, two undergraduates who will mentor freshmen in the upcoming boot camp, said they could have used some help adapting to university life when they first came on campus.―One of the hardest things I had to deal with from a social aspect was having to deal with a roommate who was a slob, but he moved out six weeks into the semester,‖Gomez said. ―Then there were five guys who lived on the same floor and played video games until five in the morning.‖On the academic side, Gomez, who wants to become a dentist, and Reynolds, a pre-med student, found the work load much harder than they expected.―You have to learn to manage the credit load and the intensity at which each professor teaches their class,‖ Gomez said. ―In an hour and 15 minutes they go through two-and-a-half chapters of information.‖Freshmen will learn that exams are crucial to their grades, Reynolds said.―In a lot of the courses you take, the grades are based mainly on exams, whereas in high school, you had homework and extra credit that could boost your grades in the end if you messed up on a test,‖ she said. ―That‘s not the case so much in college.‖Gomez said the newly found freedom that freshman experience when they leave home poses another danger, Gomez said.―Some freshmen are like, ‗I‘m away from mom and dad and there‘s a party down the street and I can sta y up until 3 in the morning,‘‖ he said.―But if you only get two hours sleep, you're probably not going to function well the next day. So with that freedom comes responsibility and knowing your limits,‖ Gomez said.(By Lenita and Reno Gazette, from USA TODAY, May 12, 2013.) Choose the right answer to the following questions:1.What do freshmen do in the academic boot camp?A.They are to be trained for combat.B.They scrub the latrines with toothbrushes.C.They overcome their shortcomings.D.They attend classes, work in groups and take exams.2.

The boot camp can help freshmen change their roles from middle school students tocollege students in a short time.C. The boot camp is open to all of freshmen.D. Freshmen can have chance to experience tougher academic requirements of highereducation before the start their university.4. What do we know about mentors?A.

And it‘s true kids won‘t always follow your health and safety rules. But studies show parents who keep setting boundaries make a huge difference.The latest example is a survey on media use by the Kaiser Family Foundation. It found that typical kids ages 8 to18 spend an astonishing 7 hours and 38 minutes a day consuming entertainment media, including deeply in TV, computer, games, cellphones, music players and other devices while occasionally glancing at books and other non-electronic media. Many experts, including the pediatrics (小儿科) academy,consider that much screen time bad for mental and physical health.But the study also found that kids whose parents set any time or content limits were plugged in for three hours less day.‖ Parents can have a big influence ,‖ says Kasier Vicky Rideout.―The reality is that teenagers care deeply what their parents think,‖ says Kenneth Ginsburg, a specialist of the Children‘s Hospital of Philadelphia. ―the challenge for parents is to get across rules and boundaries in a way that doesn‘t feel controlling.‖Research shows that parents who set firm rules but explain and enforce in a warmsupportive way work better than those who set no rules, fail to enforce them or rule with a ―because I said so‖ iron grip.Ideally, ―kids understand the rules are about their well-being and safety,‖ Ginsburg says.Still, achieving just-right parenting is ―challenging‖‘ says Margaret Broe-Eitzpatrick, a teacher in Kensington, Md. ,who has four children, age 8 to 16.‖There are so many different things to keep track of.‖ She and her h usband keep their kids busy with sports and other activities, limit screen time and review the music their children download. They talk with their 16-year-old son about the rules he‘ll face when he gets a driver‘s license soon. But she says, they can‘t pol ice everything the kids encounter on the Internet or in friends‘ homes.―We‘re just doing the best we can ‗‖ she says ‗‖even if young people may protest at first, they do feel more safe and secure when limits are set.‖6. The survey by the Kaiser Family Foundation is mentioned to illustrate the idea that_____.A)Kids don‘t always follow parents‘ rules B) only few parents believe thegood newsC)Much media use results in bad health D) parents‘ rule make a hugedifference7. What did the kids do when parents set any time or content limits, according to the Kaiser Family Foundation?A)They cut down on their screen time. B) They appreciated their parents‘ love.B)They spent more time staying outdoors. D) They accepted parents‘ rulesunwillingly.8. What will Kenneth Ginsburg most probably suggest that parents should do?A) Avoid setting firm rules. B) Avoid ruling with an iron grip.C) Set rules after family discussion. D) Set rules that are easy to understand.9. Margaret Broe-Fitzpatrick finds it impossible_____.A) to achieve just-right parenting B) to keep track of everything done by the kidsC) for the kids to face rules alone D) for the kids to observe rule without protest10. The passage is mainly intended for parents_____.A ) whose kids have difficulty in self-discipline B) whose kids are addicted to media useC ) Who have doubts about setting rules D) who are too busy to care for their kids(答案:6-10 DABBC)Passage ThreeEarlier this year I met with a group of women in Matela, a small farming village in Tanzania, and we discussed something that‘s been on all of our minds lately: finding a safe place to save money. The women said their babies were getting sick form malaria,and they could afford the drugs if they saved money over time-but with no access to formal savings accounts, they had a hard time safeguarding cash. So they saved in risky and inefficient ways. They made loans to each other, or bought goats or jewelry, then sold them if they suddenly needed money.The success of microloans has opened new opportunities for many poor people and has been a crucial factor in reducing poverty. But loans are not enough. Savings accounts could help people in the developing world with unexpected events, accumulate money to invest in education, increase their productivity and income, and build their financial security. Fortunately, this is a moment of opportunity. New policy ideas are uniting in ways that will lower the cost of savings and bring safe financial services to the doorsteps of the poor.One exciting trend is agent banking in which stores and post offices serve as banking outlets. Banks still manage and guarantee the deposits, but they rely on the infrastructure of other outlets to deal with clients where there are no bank branches. The phenomenal growth of mobile phones in the developing world presents another opportunity. M-Pesa , the mobile-phone cash-transfer service in Kenya, has signed up more than 5 million subscribers in two years and recently expanded to Tanzania. This new idea is opening markets and transforming lives. A split-second M-Pesa transaction cots as little as 30 cents and replaces a day of risk and expense just to send someone money or carry earnings home.At the Gates Foundation, it has been committed more than $350 million to make financial services widely accessible to the poor because safe places to save can help break the cycle of poverty. If action is taken on this moment, then within a generation, billions of people will have the chance to build up their saving and live the healthy, productive lives that they deserve.11. According to the first paragraph, people in Matela are most likely to expect that_____A) They can afford the cure for malaria B) They can save their cash efficientlyC) They can live safely in the village D) Their can get rid of poverty soon12. What can help the poor build financial security?A) Getting B) Lower cost of savingC) Chances for education D)Saving services13. What is the role of post offices in ―agent banking‖?A) They are subordinate to banks. B) They are cooperative with banksC) They are taking the place of banks D) They are being changed into banks14.. Compared with agent banking, M-Pesa most probably______A) is less practical for poor people B) is more popular among clientsC) costs less except transaction fees D) provides safer savings accounts15.Gates Foundation intends to make financial services______A) affordable B)widely recognized C).influential D)easily obtained (答案:11-15 BDBCD)Part II. Reading in DepthDirections: In this section, there is a passage with ten blanks. 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 or a combination of letters. Please choose the corresponding letter or combination for each item on. You may not use any of the words in the bank more than once.And yet, even as the financial pages wrote the paper‘s obit, deep within that fancy Renzo Piano palace across from the Port Authority, something hopeful has been going on: a kindof---16---.

K 17.J 18G 19H 20.F 21D 22.B 23.E 24.C 25.A )Part III To Detect the InformationDirections: 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.A) .Michelle , Stetson MBA graduate, dreamed in college of owning her own business and conducted informational interviews with entrepreneurs. ―This experience was eye-opening to say the least,‖ Michelle says. ―Until interviewing the folks I talked to, I had an almost romantic notion of being in business for one‘s self. After our discussions, I had a better picture of the trials, heartaches and triumphs involved.‖Based on what she learned, Michelle chose to learn the ropes from the corporate world before venturing her own enterprise.B). Management graduate J.P. Politano notes that before he conducted his informational interviews he was completely unsure of what kind of job he wanted.―Speaking with my interviewee made me realize that many of my points ofview ,experiences, and desires pointed me to a field like consulting, but I had never known it until we talked. It was introduced for the first time to something that I had been seeking for years, but was unsure of what it was,‖ Politano says.C ) You can narrow a wide field down to a special job. ―Informational interviews helped me to learn more about what areas of accounting I may want to enter and chose areas that I don‘t ,‖ says Tina , a senior accounting major at Stetson.D)Many job seekers learn through informational interviews that the career‘s average salary, hours, working conditions, or opportunities for advancement are not what they imagined. I actually thought of going into law, Says Stetson marketing senior Miller, ―but I decided against it‖, partly ,Miller says , From hearing an attorney‘s first hand experience that they have such crazy hours that can be very stressful.E)Although the interviewee offered a negative view of the law profession, the interviewing process showed her law was the right choice for her. ―Since my interviewees were all of different ages and genders, I got a grasp of the feeling each one had for the field. They made me realize how I would like to be as an attorney. F) . When we meet people for the first time, we often make decisions about them based on how they look. And, of course it‘s something that works both ways, for we too are being judged on our appearance. When we look good, we feel good, which in turn leads to a more confident and self-assured manner. People then pick up on this confidence and respond positively towards us. Undoubtedly, it‘s what‘s inside that‘s important, but sometimes we can send out the wrong signals simply by wearing inappropriate clothing or not spending enough time thinking about how others see us.G) For example, people often make the mistakes of trying to look like someone else they‘ve seen in a magazine, but this is usually a disaster as we all have our own characteristics. Stand in front of a full length mirror and be honest with yourself about what you see, There is no need to dwell on your faults—we all had good points and bad points---bue think instead about the best way to emphasize the good ones.H) When selecting your clothes each day, think who you‘re likely to meet, where you‘re going to be spending most of your time and what tasks you are likely to perform. Clearly , some outfits will be more appropriate to different sorts of activity and this will dictate your choice to an extent. However, there‘s no need to abandon your individual taste completely. After all, if you dress to please somebody else‘s idea of what looks good, you may end up feeling uncomfortable and not quite yourself.I) But to know your own mind, you have to know yourself. What do you truly feel good in ? There are probably a few favourate items that you wear a lot---most people wear 20 per cent of their wardrobe 80 per cent of the time. Look at these clothes and ask yourself what they have in common. Are they neat and tidy? Loose and flowing? Then look at the things hanging in your wardrobe that you don‘t wear and ask yourself why. Go through a few magazines and catalogues and mark the things that catch your eyes. Is there a common theme?J)Some colors bring your natural colouring to life and others can give us a washed-out appearance . Try out new colors by all means, but remember that dressing in bright colors when you really like subtle neutral tones, or vice versa, will make you feel self—conscious and uncomfortable. You know deep down where your own taste boundaries lie. And although it is good to challenge those sometimes with new combinations or shades, take care not to go too far all at once.26. Learn about the Realities of the Work World and What to expect.27. Discover potential opportunities.28. Affirm your dream career.29. Find the career you wanted may be wrong for you.30. Distinguish which career path to follow.31. Learning to be realistic.32. Making regular conscious choices.33. Analyzing your own taste.34. Being cautious when experimenting35. One‘s appearance may send out mixed information(26-35ABEDC G H I J F)Part IV TranslationDirections: translate the following sentences into Chinese:36. But souring prices and gas lines and growing crime as told to us by our parents and throughgritty world of Taxi Driver still stands out to me as what true economic calamity is all about.(但是通过父母的的讲述以及电影《出租车司机》所反映出的逼真世界,我们了解到那时候物价和燃气价格飞涨,犯罪率急剧上升,这些都清晰地向我展示出经济灾难的真实面目。

Reading Comprehension (40 points)Directions:There are 4 passages in this part. Each passage is followed by 5 questions. For each question there are 4 choices marked A, B, C, and D. Please choose the best answer to the question.Passage OneVitamins are a group if substances found in food. The body needs them for life and health. So naturally, many people are concerned with the question: Am I getting enough vitamins. And am I getting the right kind?Even though very small amounts of each vitamin are enough for the needs of the body, that many people have not enough vitamins has some basis, and this has something to do with their diet— the food they take in. A person eating a good variety of foods gets all the vitamins now known to be needed, with the possible exception of D.The problem is that there are many people who don’t choose foods wisely, don’t get enough variety, and don’t eat the basic fo ods they need to get their vitamins. So the answer to this question is: No extra vitamins are needed, if you eat proper food. In fact, many of the vitamins can not be stored in the body, so when extra vitamins are taken in, the body simply gets rid of them, It is even harmful to put too much of certain vitamins into the body. This has been found to be true of vitamin A and D, when large amounts are taken in.What foods supply what vitamins? Here is a general idea. Vitamin A, for the health of the eyes, skin, teeth, and bones, is found in green vegetables, fruits, eggs, liver and butter. Vitamin B1, which helps the nervous and digestive systems and prevents certain diseases, is found in cereals, pork and liver. VitaminB2 is found in milk, eggs, green vegetables and meats. Vitamin C, which helps boned and teeth, is found in tomatoes, certain fruits and vegetables. These are only a few of the most important vitamins the body needs.21. Our body needs _________ for life and health.A. small amounts of each vitaminB. extra vitaminsC. all vitamins except vitamin DD. large amounts of certain vitamins22. Vitamin A is needed by _________ and can be found in _________.A. bones, porkB. nervous system, milkC. eyes, green vegetablesD. teeth, meats23. Vitamin B1 is very important to_________.A. the digestive systemB. bonesC. liverD. skin24. What will be the result if you take more vitamins than you really need?A. They will do great harm to our body.B. We get all the vitamins needed.C. Our body will function moreD. Our body simply gets rid of them.properly.25. The passage has probably been taken from_________.A. a sports magazineB. a journal of medical scienceC. an aged magazineD. a youth journalPassage TwoIdeal conditions for flying a kite are a large open space like field or a beach, and a steady wind, blowing from one direction, without any sudden gusts. Avoid spots such as clearings or river banks, where the wind is likely to change suddenly, Small kites will be much easier to launch in a gentle wind, and may well tear if the wind is too strong. Big kites on the other hand, will only take off in a reasonably strong wind. Stand with your back to the wind and un wind several meters of line, holding the kite at arm’s length and pulling on the line gently. With a larger kite, ask friend to help. He should stand a little way off, the kite held out in front of him and let go when you give the signal. A kite should never be thrown into the air, but simply released when the wind is strong enough to lift it.Be very careful how you handle your kite and try to avoid any sudden movement once it is in the air. If a particularly violent gust of wind causes it to lose height, unwind a little of the line. Never pull it along on the ground once it has come down, or you will tear it.If you want to bring kite down in a hurry, make the line fast or give it to someone to hold, put your arm over the line and run towards the kite. Always take a pair of scissors, some glue and two or three strips of crepe paper with you for on-the-spot repairs.Never fly a kite near a railway line or a busy road. If the kite comes down suddenly in front of a car, it may cause and accident. Never fly a kite in stormy weather because it could act as a lightning conductor (with you as the earth)!26. Where do people often fly kites?A. In a large open field with sudden gusts.B. In a large open area with a strong wind.C. In a large open space with a steady wind blowing fro one direction.D. At a beach with a gentle wind.27. The passage is mainly about_________.A. the significance of flying a kiteB. the place selection and ways of flying akiteC. some warnings to flying a kiteD. both B and C.28. The underlined word “clearings” in the first paragraph probably means_________.A. open spacesB. large playing-groundsC. places for clearing thingsD. areas which are very clear29. According to the passage, how should we bring a kite down in a hurry?A. Pull the line gently and run towards the kite.B. Fix the line to a place, put the arm over the line and run towards the kite.C. Give the kite to someone to hold, put the arm over the line and run towards the kite.D. Pull the kite and wind the line fast.30. Which of the following can be inferred from the passage?A. Most people like to fly kites.B. Flying a kite near a railway line is dangerous.C. It is very difficult to find and ideal space for flying a kite.D. There are many ways in which people fly their kites.Passage ThreeMany people think that when they become rich and successful, happiness will naturally follow. Let me tell you that nothing is further from the truth. The world is full of very rich people who are as miserable as if they ere living in hell. We have read stories about movie stars who committed suicide or died from drugs. Quite clearly, money is not the only answer to all problems.Wealth obtained through dishonest means does not bring happiness. Lottery winnings do not bring happiness. Gambling winnings do not bring happiness. To my mind, the secret to happiness lies in your successful work, in your contribution towards others’ happiness and in luck or dishonest means, you will know that it is ill-gamed money. If you get your money by taking advantage of others or by hurting others, your wealth will not be happy with it. You will think you are a base person.Long-term happiness is based on honesty, productive work, contribution, and self-esteem. Happiness is not an end: It is a process. It is a continuous process of honest, productive work which makes a real contribution to others and makes you feel you are a useful, worthy person. As Dr. Wayne wrote, “Ther e is no way to happiness. Happiness is the way.” There is no use saying “Someday when I achieve these goals, when I get a car, build a house and own my own business, then I will be really happy.” Life just does not work that way. If you wait for certain things to happen and depend on the external circumstances of life to make you happy, you will always feel unfulfilled. There will always be something missing.31. The best title for this passage is______.A. What is HappinessB. HappinessC. Wealth and HappinessD. Process of Happiness32. According to this passage, which of the following statement is right?A. The richer you’re, the happier you’re.B. Wealth means happiness.C. Movie stars are happy.D. Rich people are not always happy.33. In the second paragraph, the word “means” is equal to ______. .A. waysB. worksC. placesD. hearts34. Long-term happiness is based on the following except______.A. self-esteemB. contributionC. productive workD. lottery winnings35. According to the passage, a person feels happy when he______.A. gets a carB. builds a houseC. owns his own businessD. feels that he is a useful, worthy personPassage FourUnder normal conditions, the act of communication requires the presence of at leasttwo persons: one who sends and one who receives the communication. In order to communicate thoughts and feelings, there must be a conventional system of signs orsymbols that mean the same to the sender and the receiver.The means of communication are too numerous and varied for systematic classification; therefore, the analysis must begin with the means of receiving communication. Reception of communication is achieved by our senses. Sight, hearing, and touching seem to play themost important roles. Smell and taste play very limited roles, for they cannot receive intellectual expression from fully developed systems of sings and symbols.Examples of visual communication are gesture and imitation. Although both frequently accompany speech, there are systems that rely solely on sight, such as those used by deafand dumb persons. Another means of communicating visually is by signals of fire, smoke,flags, or flashing light. Feelings may be simply communicated by touch, such as by handshaking or backslapping, although a highly developed system of hand-stroking hasenabled blind, deaf, and dumb persons to communicate intelligently. Whistling to someone, applauding in a theater, and other forms of communication by sound rely upon the ear as areceiver. The most fully developed form of auditory communication is, of course, thespoken language.The means of communication mentioned so far have two features in common: they lastonly a short time, and the persons involved must be relatively close to each other. Therefore,all are restricted in time and space.36. Reception of communication ___________A. is more important than sending messagesB. depends on two personsC. involves use of the sensesD. play only limited roles37. Applauding is specifically mentioned as an example of __________.A. communication by soundB. gesture and imitationC. communication by sending a messageD. communication between the listener and speaker38. Persons who cannot see, hear, or speak are able to communicate through_________.A. gesturingB. handshakingC. smellingD. hand-stroking39. The author specifically mentions that speech is ____________ .A. often used when other means are impossibleB. necessary for normal communicationC. the only highly developed system of communicationD. the most developed form of communication based on hearing40. According to the passage means of communication __________.A. can develop quickly if there is enough time and space/B. all have the same featuresC. have some limitations even if they are fully developedD. depend on the persons involvedPart III Vocabulary and Structure (25 points)Section ADirections: There are 15 incomplete sentences in this part.
