Grammar and VocabularySection ADirections: After reading the passages below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.(A)One of my most surprising findings as a student is 25 parents do not always accept your adulthood. I was always told that once you get to college, your parents realize that you have been living 26 your own and can make your own decisions. This idea was rejected 27 I came home for Thanksgiving. At first, everything was going as 28 (smoothly) as possible. The first night I went to the Berkeley campus to visit my friend Sara, without any argument from my mother. 29 when I called her to say I had decided to spend the night at Sara’s dorm, my mom informed me that she wanted me home at one a.m. I was wild with anger! I 30 (make) my own decisions how late a young man should stay out for several months. However much I tried to reason with my mother, she insisted things are different when I am home, and that they were the 31 paying my bills. And kids, this is true. No matter how much you want to fight it, mommy and daddy are still holding the purse strings, whether you are 18 or not. Sometimes it is best to sit back, shut up, and do 32 they ask.(B)A land free from destruction, plus wealth, natural resources, and labor supply —all these were important factors in helping England to become the center for the Industrial Revolution, but they were not enough. Something else 33 (need) to start the industrial process. That ―something special‖ was men —creative individuals 34 could invent machines, find new sources of power, and establish business organizations to reshape society.The men who created the machines of the Industrial Revolution came from many backgrounds and many occupations. Many of them were more inventors than scientists. A pure scientist appreciates 35 (conduct) his research accurately. He is not necessarily working 36 ______ his findings can be used. An inventor or one interested in applied science is usually trying to make something that has a concrete use. He may strive 37 (solve) a problem by using the theories of science or by experimenting through trial and error. Regardless of his method, he is working to obtain 38 specific result: the construction of a harvesting machine, the burning of a light bulb, or one of many other objectives.Many of the people who developed the machines of the Industrial Revolution were inventors, not 39 (train) scientists. A few were both scientists and inventors. Even those who had little or no training in science 40 not have made their inventions if a groundwork had not been laid by scientists years before.Section BDirections: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.Officials at Boston College have made w hat may be a critical decision: they’ve stopped giving out new email accounts to incoming students. The officials realized that the students had already established digital 41 by the time they entered college, so the new email addresses were just not being used, but, 42 , the college will offer forwarding (转发) services.Starting next year, freshman 43 at Boston College won’t be given an actual email account complete with login and inbox, just an email address. This address, in the format of johnsmith@bc. edu will simply forward mail to the student’s already 44 inbox, be it Gmail, Windows Live Mail, Yahoo Mail, AOL, or whatever else they may be using.The college reached a smart decision after first looking into outsourcing（外包）their email to the cloud. While the Boston College decision may have been made for 45 reasons more than anything, we can easily imagine this as being the start of a new trend.Can you even imagine a U.S. college student who didn’t have an email address of their ownb y the time they were a freshman? It’s 46 unheard of. Today’s students are digital47 immersed (浸润) in technology from the day they were born. It simply doesn’t make sense to give them yet another account to manage when they enter college.By going this 48 , there are still some challenges to overcome, though. For example, a student who changes their email carrier will probably forget to 49 the institution to the change and could then miss out on 50 messages from the university with regard to their courses, scholarship, safety information, etc.In the end, we think the decision Boston College made could easily be the start of a new trend. We’re sure the students like it, too.III. Reading ComprehensionSection ADirections:For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Napping for a while at daytime is a very smart and healthy move. The Mayo Clinic says naps 51 relaxation, better mood and alertness, and a sharper working 52 . A 2008 British study found that compared to getting more nighttime sleep, a mid-day nap was the best way to53 the mid-afternoon sleepiness.According to the Harvard Health Letter, several studies have shown that people 54 new information better when they take a nap shortly after learning it. And, most 55 , a 2007 study of nearly 24,000 Greek adults in the Archives of Internal Medicine found that people who napped 56 had a 37 percent reduced risk of dying from heart disease compared to people who didn’t nap.Of course, napping isn’t 57 for everyone. If you’re suffering from inability to sleep, naps that are too long or taken too late in the day can 58 with your ability to fall or stay asleep at night.But for most, naps can make you feel sharper and happier. Naps provide different benefits59 on how long they are. A 20-minute nap will boost alertness and concentration; a 90-minute snooze（小睡）can 60 creativity.According to , you 61 a natural dip in body temperature between 1 p.m. and 3 p.m. A short nap at this time can boost alertness for several hours and, for most people, shouldn’t 62 being able to fall asleep at night.Pick a dark, cozy place that’s not too warm or too chilly. 63 napping on the couch instead of in bed, so you’re less64 to snooze for too long.Surprisingly, the best place to take a nap may be a hammock（吊床）if you have one. A Swiss study 65 last year found that people fell asleep faster and had deeper sleep when they napped in a hammock than in a bed. That same rocking motion that puts babies to sleep works wonders for grown-ups, too.51. A. relieve B. promote C. operate D. support52. A. feeling B. frame C. sense D. mind53. A. cope with B. put aside C. talk about D. carry upon54. A. remark B. consider C. remember D. concern55. A. reportedly B. unbelievably C. constantly D. frankly56.

A. postpones B. discourages C. acknowledges D. recommends64. A. obliged B. tempted C. adopted D. attracted65. A. pronounced B. published C. discovered D. cultivated Section BDirections:Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Like many other small boys, I was fascinated by cars, especially because my oldest brother was a bit of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend. Every so often, one of those magazines would run an article on the ―Car of the Future‖. They featured unconventional things like small nuclear reactors as power sources. Yet, frankly, my car doesn’t do anything that my brother’s Studebaker didn’t do. It goes, it stops, it burns gasoline.I still have to steer it, and it still runs into things if I don’t steer it carefully.But guess what? All of these things are likely to change in the not-so-distant future. It may not burn gasoline, I may not have to steer it, and it may be a lot better at not running into things.Airbags aren’t the be-all and end-all in safety. In fact, considering the recent news about people occasionally being killed by their airbags in low-speed crashes, they obviously still need some development. But they aren’t going away, and in fact, you can expect to see cars appearing with additional, side-impact airbags, something some European car manufacturers already offer.Better than systems to minimize injury in the event of an accident, however, are systems that minimize the likelihood of an accident happening in the first place? Future cars may be able to remove many of the major causes of accidents, including drunk-driving, and tailgating (与前车距离过近). Cars could be equipped with sensors that can detect alcohol in a driver’s system and prevent the car from being started, for example. As early as next year, you’ll be able to buy cars with radar-equipped control s ystems. If the radar determines you’re closing too quickly with the car in front, it will ease up on the throttle（油门）.Scientists are now working on a system that can brake, accelerate and steer a vehicle down a highway on its own. Will cars eventually be able to drive themselves?66. The author was fascinated by cars because ________.A. other small boys liked to own a car of their own, tooB. he read untraditional things about cars in his brother’s magazinesC. his oldest brother loved to take him to places in his carD. he often booked cool car magazines himself67. By saying ―my car doesn’t do anything that my brother’s Studebaker didn’t do‖, theauthor means that ________.A. my car is far better than my brother’sB. my car is not as good as my broth er’sC. much improvement has been made in the design of cars recentlyD. not much has changed in the performance of cars so far68. Which of the following statements is true of airbags?A. They are going to disappear gradually.B. They are in need of further improvement.C. They are a standard feature of European cars.D. They kill people instead of protecting them in low-speed crashes.69. According to the author, what will future cars do if the sensors detect alcohol in the driver’ssystem?A. They will not start.B. They will ease up on the throttle.C. They will brake automatically.D. They will give a warning in advance.(B)Suppose you work in a big firm and find English very important for your job because youoften deal with foreign businessmen. Now you are looking for a place where you can improve your English, especially your spoken English.Here are some advertisements about English language training from newspapers. You may find the information you need.70. You work from 9:00 a. m. to 4:30 p. m. every day. Which school will you choose?A. Global English Center and the International House.B. Global English Center and Modem Language School.C. Modern Language School and the 21st Century.D. The 21st Century and the International House.71. The 21st Century is different from the other three schools in that ________.A. its teaching quality is betterB. it requires an entrance examinationC. its courses are more advancedD. it is nearest to the city center72. You will probably prefer to go to the International House because it ________.A. offers sightseeing and social activities at low pricesB. costs less than the other schoolsC. has a special course in spoken EnglishD. has native English teachers73. If you take the four-month evening program at the International House, you will pay about________.A. 60 yuanB. 240 yuanC. 720 yuanD. 960 yuan(C)Western airliner manufacturers seem to be tripping over (绊倒) themselves in their eagerness to sign cooperative agreements with Asian partners as a low-cost route to developing new airliners. Their potential Asian partners seem to be tripping over themselves to sign such agreements, as a low-cost route to acquiring new airliner technology. If they are not careful the two sides will end up tripping over each other: the one by selling its birth-right for short-term gain, the other by trying to break into a market which isn’t big enough to sustain (忍受) it.Technology transfer works in a growing market, where the aspirations of the new entrant receiving that technology can be met through expansion. The airliner market is not such a device.Even the most optimistic projections of airliner sales for the next 20 years show that airliner manufacture can only be profitable if a small number of aircraft builders share the available sales. It follows that if new manufacturers come into the market and take sales, their sales must come from substitution, not expansion.Given the complexity of today’s airliners, it is unlikely that any new entrant will have both the financial and technical resources to come into the market without the involvement of an established manufacturer. In the short term, such involvement may not be to the exclusive benefit of the new entrant: most of the established manufacturers are searching for ways to reduce costs of manufacture.In the short term, it can be of benefit to an established Western manufacturer to have either components of complete air–frames made or assembled in lower-wage economics such as China, Taiwan or Korea, while retaining the design, development and marketing of aircraft for itself. It would be a very unwise Western manufacturer which did not notice the fact that these developing economies are acquiring skills (like computing) at least as quickly as they are acquiring skills in metal bashing (猛击).The danger comes when the new entrant no longer needs the established Western partner because it has acquired the technical and intellectual ability to design and build its own aircraft. An Asian partner may well find itself in the happy position of having the low-cost labour base, the high-cost technology base and the vital financial base to build a new airliner.74. T he author’s attitude towards Western/Eastern cooperation can be described as ________.A. positiveB. progressiveC. conservativeD. negative75. ―The airliner market is not such a device‖ means that the airliner market ________.A. does not encourage technology transferB. is too limited to offer chances of successC. requires hi-tech rather than unaccepted devicesD. is full of competitions for new entrants76. According to the author, a wise established manufacturer should ________.A. try to benefit from both financial and technical resourcesB. break up his partnership with the East once profits are madeC. keep a tight told over hi-tech development and marketing of airlinersD. cooperate with Asian partners for a short time77. The word ―base‖ i n the last paragraph represents ________.A. a place for aircraft productionB. the operation of aircraftC. a research instituteD. a position where to build officeSection CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.―There is a senseless concept that children grow up and leave home when they are 18, and the truth is far from that,‖ says sociologist Larry Bumpass of the University of Wisconsin. Today, unexpected numbers of young adults are living with their parents.Analysts raised a variety of reasons for this return to the nest. One important reason is that the marriage age is rising, a condition that makes home and its pleasantness particularly attractive to young people, which is second to skyrocketing housing costs to which young people find their wings attached. Besides, a high divorce rate and a declining remarriage rate are sending economically pressed and emotionally hurt survivors back to parental shelters. For some, the expense of an away-from-home college education has become so great that many students now attend local schools.Living at home, says Knighton, a school teacher, continues to give her security and moral support. Her mother agreed, ―It is ri diculous for the kids to pay all that money for rent. It makes sense for kids to stay at home.‖ But sharing the family home requires adjustments for all. There are the quarrels over bathrooms, telephones and privacy. Some families, however, manage the delicate balancing act. But for others, it proves too difficult. Michelle Del Turco, 24, has been home three times —and left three times. ―What I considered a social drink, my dad considered an alcohol problem,‖ she explains. ―He never liked anyone I dated, s o I either had to hide away tomeet them at friends’ houses.‖It is really hard to say how long adult children should live with their parents before moving on. Nevertheless, it is commonly recognized that lengthy homecomings are a mistake and they accidentally destroy the advantage of brief visits that will strengthen the relationship between parents and children. Children, struggling to establish separate identities, can end up with ―a sense of inadequacy, defeat and failure.‖ And aging parents, who should be enjoying some financial and personal freedom, find themselves stuck with responsibilities, which is definitely a stress for them. (Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.)78. What’s the most important reason for young adults’ returning to the nest?79. Knighton enjoys living at home due to ________.80. What has resulted in the Michelle Del Turco’s unhappy experience with her dad?81. From the passage, we can conclude it is ________ that benefit(s) both adult children and theirparents to avoid lengthy homecomings.第II 卷(共47分)I.
