Passage 1In recent years, more and more foreigners are involved in the teaching programs of the United States. Both the advantages and the disadvantages 47 using foreign faculty in teaching positions have to be 48 , of course. It can be said that the foreign background that makes the faculty member from abroad an asset also 49problems of adjustment, both for the university and for the individual. The foreign research scholar usually isolates himself in the laboratory as a means of protection; 50, what he needs is to be fitted to a highly organized university system quite different from 51 at home. He is faced in his daily work with differences in philosophy, arrangements of courses and methods of teaching. Both the visiting professor and his students 52 a common ground in each other’s cultures, some concept of what is already in the minds of American students is 53 for the foreign professor. While helping him to adapt himself to his new environment, the university must also 54 certain adjustments in order to take full advantage of what the newcomer can 55 . It isn’t always known how to make creative use of foreign faculty, especially at smaller colleges. This is thought to be a 56 where further study is called for. The findings of such a study will be of value to colleges and universities with foreign faculty.It seems you always forget—your reading glasses when you are rushing to work, your coat when you are going to the cleaners, your credit card when you are shopping...Such absent-mindedness may be 47 to you; now British and German scientists are developing memory glasses that record everything the 48 sees.The glasses can play back memories later to help the wearer remember things they have forgotten such as where they left their keys. And the glasses also 49 the user to "label" items so that information can be used later on. The wearer could walk around an office or a factory identifying certain 50 by pointing at them. Objects indicated are then given a 51 label on a screen inside the glasses that the user then fills in.It could be used in 52 plants by mechanics looking to identify machine parts or by electricians wiring a 53 device.A spokesman for the project said: "A car mechanic for 54 could find at aglance where a part on a certain car model is so that it can be identified and repaired. For the motorist the system could 55 accident black spots or dangers on the road."In other cases the glasses could be worn by people going on a guided tour, 56 points of interest or by people looking at panoramas where all the sites could be identified.A sunflower is a sunflower. A mobile phone is a mobile phone. But can you 47 the two to do something for your local 48 ?It may well be possible. When you have finished with your mobile phone you will be able to 49 it in the garden or a plant pot and wait for it to flower.50 , a biodegradable (生物可降解的)mobile phone was introduced by scientists. It is hoped that the new type of phone will encourage 51 to recycle.Scientists have come up with a new material over the last five years. It looks like any other 52 and can be hard or soft. and able to change shape. Overtime it can also break down into the soil without giving out any toxic 53 . British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it 54 nitrates(硝酸盐). These feed the seed and help the flower grow.Engineers have designed a small 55 window to hold the seed. They have made sure it only grows when the phone is thrown away."We've only put sunflower seeds into the covers so far. But we are working with plant 56 to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.Blue is the world's favorite color. It is also the color most often 47 with intellect and authority.Most uniforms are blue. In Greek and Roman mythology, blue is the color of sky gods. In the Old Testament, God is 48 by deep blue. Blue and turquoise (青绿色)are represented by the Islamic religion. It is the 49 color in the mosques of the world.Blue symbolizes truth, peace and cooperation. It is the color of the flag of the United Nations and of Europe. As the coolest color of the spectrum, it is the hue mostlikely to have a receding effect. As in the skies and water that 50 us, blue is seen as a peaceful and 51 color. Blue light has seen to 52 blood pressure by calming the nervous system hence relaxing the body and mind. Blue creates large airy spaces. It makes rooms bigger.The wrong shade of blue can be uncomfortable. It can also be cold and sterile(枯燥的)unless 53 with warmer colors.Light and soft blue makes us feel quiet and protected from the bustle(喧闹)and 54 of the day. Blue bedrooms are restful. Blue bath rooms are appropriately watery. Blue 55 depth with greens and reds. Dark blue represents the night making us calm. Its apparently calming effect makes it the perfect tone for the quieter 56 of your living space.Perhaps like most Americans you have some extra pounds to 47 . You may even have tried a fad diet or two, but found yourself right back where you started. The key to weight loss is regular 48 activity. And surprisingly, you don't have to give up eating or make the gym your second home to see long-term, 49 effects.You body needs a certain amount of energy to maintain basic 50 such as breathing, blood circulation and digestion. The energy required to keep your organs functioning is referred to as the resting or basal metabolic rate.Any time you are active, 51 energy is required. It is obtained from glycogen and fat stored in the blood, liver, and muscles. The key to losing weight is to draw on the fat rather than on the carbohydrate reserves.Which of the two energy sources you use depends on the intensity and 52of your activity. The higher the intensity, the more your body will pull from the stored carbohydrates. The lower the intensity, the more your body will 53 on fat as its fuel.Aerobic exercise is most 54 for weight loss. When you perform aerobic activities you 55 contract large muscle groups such as your legs and arms. Walking, running, rollerblading, swimming, dancing, and jumping jacks are all forms of aerobic activity.Surprisingly, if your aerobic activity is low to moderately intense and of long duration, you will burn more fat than if you had 56 in a short burst ofhigh-intensity exercise. In short, a brisk 30-minute walk will burn fat while a100-yard sprint will burn glycogen.Passage 6budgets in the six months to October, 2008, as the financial crisis has taken its toll, while supermarkets have 11 advertising spending in a battle to prove that they offer the most 12 prices.According to new research undertaken for The Daily Telegraph by Nielsen Media Research, in the six months to September 30, 2008, Marks & Spencer’s advertising spend fell 20.3pc to £25.3m, 13 with the same period in 2007.While the retailer has spent heavily on a campaign 14 celebrities in the past two years, it is understood to be cutting back on celebrity spending in 2009. The retailer is, however, still the UK’s 25th la rgest spender on advertising, 15 being at 17th place in the six months to September 30, 2007.Car manufacturers have also significantly 16 back on marketing spending, believed to be a result of the financial crisis. According to Nielsen, Ford spent £26.6m in the six months to September 30, 2008, down 21pc from the same period last year. Vauxhall also 17 spending by 15.6pc in the period to £26.5m.For supermarkets, however, a significant increase in advertising spending, it appears, is a 18 as they seek to woo (追求) increasingly price- 19 customers. The leading supermarkets have 20 an aggressive price war in the past six months as consumers have been faced with news of higher food prices.Undoubtedly the globe is getting hotter and hotter. The unavoidable questions are: How much responsibility shall we take for warming, and are we 47 to stop the destruction by limiting our insatiable 48 for natural fuels?It seems that global warming is too _49_ to be worried about, or too unpredictable. The computer_50_ cannot define what the weather is like next week. In cold winter day it might be considered that a little warming would be a fair thing. And doubtlessly: Alarming about_51_ alteration may sound like an environmentalist frightening strategy, aiming to urge humans to walk and keep the world cleaner.However, based on the data collected by scientists, bad news are brought to our living media.From California to the snowy peaks of China, the air is heating up right now, and the globe is being fast warmed, the _52_ has increased by 1 ℉ compared with the past century. In addition, some parts like remote places have been in a much hotter state. The results aren't satisfactory, ice being _53_ , rivers running dry, and coasts being _54_ , threatening villages and cottages.The 55 are gradually occurring without any obvious phenomenon. But they shouldn't slip our mind, because they can pose as a great potential threat to the 56 world.The way you go about purchasing an article or a service can actually 47 you money or can add to the cost. Take the 48 example of a hairdryer. If you are buying a hairdryer, you might think that you are making the 49 buy if you choose one whose look you like and which is also the cheapest 50 price. But when you get it home you may find that it takes twice as long as a more expensive51 to dry your hair. The cost of the electricity plus the cost of your time could well make your hairdryer the most expensive one of all。

• 较难的一个例子:Husbands and children now do some of these jobs, a ____ that has changed the target market for many products. (06-12) 这里可以用两种判断方法 来判断横线处所填词的词性。第一种方法,用句子结构来判断,前面一句话,Husbands and children now do some of these jobs,这是一个完整的句子,主语husbands and children,谓语动词DO,宾语Some of these jobs;后面的that引导的是一个同位语从 句,它所修饰的中心词就是a后面需要填的词,而定语从句的中心词是名词,所以横线处 应填一个名词。第二种方 法,根据刚才所说的“a + 名词”的语法规则来判断,横线处应 该填一个名词,而且是一个可数名词的单数形式。正确答案是situation。这句话的意思是 “丈夫和孩子现在也做一些 这样的工作了,这种情况就改变了许多产品的目标市场。”
• 2. 当出现“一个完整的句子 + ,____ + 名词/介词”的结构时,逗号后 边的部分是伴随状语,表示伴随状态或者表示原因,应当填动词加ING形 式或动词加ED形式。当这个动词与句子主语是主动关 系,填动词加ING形 式,当两者是被动关系,填动词加ED形式。
• 举例说明:
• The rainfall is increased across south america, ___ floods to peru. (06-6) 根据独立主格结构原则,应该填动词ing或动词ed,选项中只有 bringing符合要求。从意思来看,bring“带来”与rainfall“降雨”之 间 是主动关系,即“the rainfall brings floods”,所以用bringing无论从 意思上还是结构上都符合要求。

大学英语四级选词填空专项练习Passage 1What is it about Americans and food? We love to eat, but we feel 1 about it afterward. We say we want only the best, but we strangely enjoy junk food. We’re 2 with health and weight loss but face an unprecedented epidemic of obesity(肥胖). Perhaps the 3 to this ambivalence(矛盾情结) lies in our history. The first Europeans came to this continent searching for new spices but went in vain. The first cash crop(经济作物) wasn’t eaten but smoked. Then there was Prohibition, intended to prohibit drinking but actually encouraging more 4 ways of doing it.The immigrant experience, too, has been one of inharmony. Do as Romans do means eating what “real Americans” eat, but our nation’s food has come to be 5 by imports—pizza, say, or hot dogs. And some of the country’s most treasured cooking comes from people who arrived here in shackles.Perhaps it should come as no surprise then that food has been a medium for the nation’s defining struggles, whether at the Boston Tea Party or the sit ins at southern lunch counters. It is integral to our concepts of health and even morality whether one refrains from alcohol for religious reasons or evades meat for political 6 But strong opinions have not brought 7 . Americans are ambivalent about what they put in their mouths. We have become 8 of our foods, especially as we learn more about what they contain.The 9 in food is still prosperous in the American consciousness. It’s no coincidence, then, that the first Thanksgiving holds the American imagination in such bondage(束缚).

On a raw winter day you might think that a few degrees of warming wouldn’t be such a bad thing anyway. And no doubt about it: Warnings about 5 change can sound like an environmentalist scare tactic, meant to force us out of our cars and restrict our lifestyles.Comforting thoughts, perhaps. Unfortunately, however, the Earth has some discomforting news. From Alaska to the snowy peaks of the Andes the world isheating up right now, and fast. Globally, the 6 is up 1°F over the past century, but some of the coldest, most remote spots have warmed much more. The results aren’t pretty.

They have developed a hitlist of our main fears: natural resources are 1 out? the population is ever growing, leaving less and less to eat? species are becoming 2 in vast numbers, and the planet’s air and water are becoming ever more polluted.But a quick look at the facts shows a different picture. First, energy and other natural resources have become more 3 n ot less so, since the book ‘The Limits to Growth’ was published in 1972 by a group of scientists. Second, more food is now produced per 4 of the world’s population than at any time in history. Fewer people are 5 . Third, although species are indeed becoming extinct, only about 0.7% of them areexpected to disappear in the next 50 years, not 25~50%, as has so often been 6 . And finally, most forms of environmental pollution either appear to have been 7 , or are transient –associated with the early stages of industrialization and therefore best cured not by restricting economic growth, but by 8 it.

In other words, it refers to anything that is __30__ or learnt, rather than instinctive or natural. Among human populations, culture not only affects the way we live, but also writes itself into our genes, affecting who we are. For instance, having spent many generations hunting the fat marine mammals of the Arctic, the Eskimos of Greenland have developed certain genetic __31__ that help them digest and utilize this fat- rich diet, thereby allowing them to __32__ in their cold climate.Like humans, killer whales have colonized a range of different __33__ across the globe, occupying every ocean basin on the planet with an empire that __34__ from pole to pole.

We can't let that happen," says Senator Mike Kowall, the lead __31__ of four bills recently introduced.If all four bills pass as written, they would __32__ a substantial update of Michigan's 2013 law that allowed the testing of self-driving vehicles in limited conditions. Manufacturers would have nearly total freedom to test their self-driving technology on public roads. They would be allowed to send groups of self- driving cars on cross-state road trips, and even set up on-demand __33__ of self-driving cars, like the one General Motors and Lyft are building.Lawmakers in Michigan clearly want to make the state ready for the commercial application of self-driving technology. In __34__ , California, home of Silicon Valley, recently proposed far more __35__ rules that would require human drivers be ready to take the wheel, and ban commercial use of self-driving technology.(四)A.climbedB.consumeC.decadeD.determineE.effectiveF.harmfulG.outcomes H.passively I.previouslyJ.resume K.suffered L.surfingM.term N.terminals O.twistingour guilty pleasure: Watching TV is the most common everyday activity, It’safter work and sleep, in many parts of the world. Americans view five hours of TVeach day, and while we know that spending so much time sitting 36 can lead toobesity (肥胖症) and other diseases, r esearchers h ave now quantified just how 37being a couch potato can be.In an analysis of data from eight large 38 published studies, a Harvard-led groupreported in the Journal of the American Medical Association that for every two hoursper day spent channel 39 , the risk of developing Type 2 diabetes(糖尿病) rose 20%over 8.5 years, the risk of heart disease increased 15% over a 40 , and the odds ofdying prematurely 41 13% during a seven-year follow-up. All of these 42 are linkedto a lack of physical exercise. But compared with other sedentary(久坐的) activities,like knitting, viewing TV may be especially 43 at promoting unhealthy habits.

And other studies have found that watching ads for beer and popcornmay make you more likely to 44 them.Even so, the authors admit that they didn’t compare different sedentary activities to 45 whether TV watching was linked to a greater risk of diabetes, heart disease orearly death compared with, say, reading.(五)A.announcingB.beneficialC.challengesmitmentponentF.contestsG.critically H.develop I.distributingJ.enhance K.entitled L.potentialM.properly N.qualified O.retainThe U.S. Department of Education is making efforts to ensure that all students have equal access to a quality education.

What is it about Americans and food? We love to eat, but we feel _ 1 _ about it afterward. We say we want only the best, but we strangely enjoy junk food. We're 2 with health and weight loss but face an unprecedented epidemic of obesity(肥胖). Perhaps the 3 to this ambivalence(矛盾情结) lies in our history. The first Europeans came to this continent searching for new spices but went in vain. The first cash crop(经济作物) wasn’t eaten but smoked. Then there was Prohibition, intended to prohibit drinking but actually encouraging more 4 ways of doing it.The immigrant experience, too, has been one of inharmony. Do as Romans do means eating what “real Americans” eat, but our nation’s food has come to be 5 by imports—pizza, say, or hot dogs. And some of the country’s most treasured cooking comes from people who arrived here in shackles.Perhaps it should come as no surprise then that food has been a medium for the nation’s defining struggles, whether at the Boston Tea Party or the sit-ins at southern lunch counters. It is integral to our concepts of health and even morality whether one refrains from alcohol for religious reasons or evades meat for political 6 .But strong opinions have not brought 7 . Americans are ambivalent about what they put in their mouths. We have become 8 of our foods, especially as we learn more about what they contain.The 9 in food is still prosperous in the American consciousness. It's no coincidence, then, that the first Thanksgiving holds the American imagination in such bondage(束缚). It's what we eat—and how we 10 it with friends, family, and strangers—that help define America as a community today.A. answerB. resultC. shareD. guiltyE. constantF. definedG. vanishH. adaptedI. creativeJ. beliefK. suspiciousL. certainty M. obsessed N. identify O. ideals答案详解:1. D feel是一个系动词,可以判断此处应填入一个形容词,通过上下文意思,以及后面介词about, 可以确定选项为D项guilty, 短语feel guilty about sth. "对……感到有愧"。
全句的意思为"我们很爱吃,但是往往在吃完之后又有负罪感"。
2. M be obsessed with 为固定搭配,原意为"被……附上/缠住/迷住心窍",放在本句表示"十分重视"。
全句的意思为"我们很关心健康和减肥,但肥胖却又空前地在蔓延"。
3. A 本句缺一个名词作主语,并且根据和介词to的搭配,可以推断出正确选项answer.4. I 本句根据more和ways可以判断出需要填入一个形容词构成比较级,根据上下文,表示"旨在禁止酗酒的禁酒令,却激发了更多新奇的方法来酗酒",可以确定I为正确选项。
5. F 本题较难。
根据be 和by 确定应填入一个过去分词。
再根据上下文,上文表示"应该吃典型的美国人吃的食物",下文通过 but 转折,表示实际上"美国的食物已经被诸如比萨和热狗这样的舶来品所诠释了",因此可以确定F为正确选项。
6. B 政治结果,可根据宗教原因religious reasons来推断此处填政治结果。
7. L 由于横线后面没有宾语,可以确定不是形成bring的短语,这样本句所缺的为一名词,做bring的宾语。
