1. Passage Thirty-FourMuch unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction.Computers are often used as part of automated (自动化的)production systems requiring a least possible number of operators， causing the loss of many jobs.This has happened， for example， in many steelworks.On the other hand， computers do create jobs.They are more skilled and better paid， though fewer in number than those they replace.Many activities could not continue in their present form without computers， no matter how many people are employed.Examples are the check clearing (交换)system of major banks and the weather forecasting system.When a firm introduces computers， a few people are usually employed in key posts (such as jobs of operations managers)while other staff are re-trained as operators， programmers， and data preparation staff.After the new system has settled down， people in non-computer jobs are not always replaced when they leave， resulting in a decrease in the number of employees.This decrease is sometimes balanced by a substantial increase in the activity of the firm， resulting from the introduction of computers.The attitudes of workers towards computers vary.There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers， making promotion for older workers not skilled in computers more difficult.On the other hand， many workers regard the trend toward wider use of computers inevitable.They realize that computers bring about greater efficiency and productivity， which will improve the condition of the whole economy， and lead to the creation of more jobs.This view was supported by the former British Prime Minister， James Callaghan in 1954， when he made the point that new technologies hold the key to increased productivity， which will benefit the economy in the long run.The unfriendly feeling towards computers is developed from ().

3. Passage Twenty-OneWhat will man be like in the future—in 5，000 or even 50，000 years from now? We can only make guesses， of course， but we can be sure that he will be different from what he is today.For man is slowly changing all the time.Let us take an obvious example.Man， even five hundred years ago， was shorter than he is today.Now， on average， men are about three inches taller.Five hundred years is relatively short period of time， so we may assume that man will continue to grow taller.Again， in the modern world we use our brains a great deal.Even so， we still make use of only about 20% of the brain’s capacity.As time goes on， however， we shall have to use our brains more and more， and eventually we shall need larger ones.This is likely to bring about a physical change to the head， in particular the forehead will grow larger.Nowadays our eyes are in constant use.In fact， we use them so much that very often they become weaker and we have to wear glasses.But over very long period of time it is likely that man’s eyes will grow stronger.On the other hand， we tend to make less use of our arms and legs.These， as a result， are likely to grow weaker.At the same time， however， our fingers will grow more sensitive because they are used a great deal in modern life.But what about hair? It will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer.In the future， then， both sexes are likely to be bald.Perhaps all this gives the impression that future man will not be a very attractive creature to look at.This may well be true.All the same， in spite of all these changes， future man will still have a lot in common with us.He will still be a human being， with thoughts and emotions similar to our own.Man’s forehead will grow larger because ().

35. Questions 31 to 35 are based on the following passage.To write his 2010 book， The 5-Factor World Diet， nutritionist Harley Pasternak traveled to the healthiest countries around the world to learn more about what made their meals extra nourishing.He noted that Japanese people ate a wonderful variety of seaweeds， and that Chinese people tried to include at least five different colors in every meal.Pasternak also came away with some valuable observations about how different the North American way of life was， compared with many other countries.For starters， Americans eat much bigger portions than people in other countries.“We don’t prioritize eating seasonally or locally， and we also add lots of salt， sugar and thickening agents to our foods，” explained Pasternak.Contrast that to the healthy Mediterranean， Nordic and Okinawan diets listed in Pasternak＇s book.They all seem to stick to the ethos (特质)of regional， seasonal produce.For example， a traditional Mediterranean diet includes fruits， vegetables， whole grains， nuts and olive oil as the main components of nutritional intake.Fish， chicken and red wine make moderate appearances， while red meat， salt and sugar are used much less often.The benefits of a traditional Mediterranean diet have been studied since the 1970s， and researchers have found that living that olive oil life can help people lose weight， lower their heart disease risk and reverse diabetes.Most other healthy eating cultures also make meals an event—say， multiple courses around the family table， or a glass or two of red wine at a long lunch—opposed to hastily wolfing down handfuls of cereal above the kitchen sink and calling it dinner.Each of the healthy eating cultures has its own unique feature.But Pasternak did take note of one unifying factor in all of the healthy societies he observed.“The only overlapping feature in most of these healthy countries is that they all walk way more than the average American，” said Pasternak.“So really， regardless of what you’re eating， if someone’s walking four miles more than you each day， they are going to be a lot thinner and live a lot longer than you.”Compared with the average American， people in healthy societies ( ).

A. 　walk at least 4 miles a dayC)pay more attention to body shape

B. 　do considerably more walkingD)consume a lot more organic food

C. 　pay more attention to body shape

D. 　consume a lot more organic food

3. Passage Twenty-NineHow can we get rid of garbage (垃圾)? Do we have enough energy sources to meet our future energy needs? These are two important questions that many people are asking today.Some people think that man might be able to solve both problems at the same time.They suggest using garbage as an energy source， and at the same time it can save the land to hold garbage.For a long time， people buried garbage or dumped (倾倒)it on empty land.Now， empty land is scarce.But more and more garbage is produced each year.However， garbage can be a good fuel to use.The things in garbage do not look like coal， petroleum， or natural gas; but they are chemically similar to these fossil fuels.As we use up our fossil-fuel supplies， we might be able to use garbage as an energy source.Burning garbage is not a new idea.Some cities in Europe and the United States have been burning garbage for years.The heat that is produced by burning garbage is used to boil water.The steam that is produced is used to make electricity or to heat nearby buildings.In Paris， France， some power plants burn almost 2 million metric tons of the city’s garbage each year.The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.Our fossil fuel supplies are limited.Burning garbage might be one kind of energy source that we can use to help meet our energy needs.This method could also reduce the amount of garbage piling up on the earth.According to the passage， which of the following is NOT true?

2. Passage ElevenDoctors say anger can be an extremely damaging emotion， unless you learn how to deal with it.They warn that anger can lead to heart disease， stomach problems， headaches， emotional problems and breast cancer.Anger is a normal emotion that we all feel from time to time.Some people express anger openly in a calm and reasonable way.Others burst with anger， screaming and yelling.But still others keep their anger inside.They cannot or will not express it.This is called (repressing)anger.For years some doctors claim that both repressing and expressing anger can be dangerous.They say that in both situations the brain of an angry person releases the same hormones (荷尔蒙).They spend the heart rate， raise blood pressure or sugar level in the blood.As a result， the angry person feels excited and is ready to react.The violent reaction may lead to high blood pressure.However， some other doctors argue that repressing anger is more dangerous to a person’s health than expressing it.They believe that those who keep their anger inside may face a greater danger of heart disease.Most doctors agree that it is important to learn how to deal with anger.They say the first step is to admit that you are angry and recognize the real cause of the anger， then decide if the cause is serious enough to get angry about.If so， you should not express your anger immediately and try to wait until your anger has cooled down， so that you are able to express yourself calmly and reasonably.They also believe that a good way to deal with anger is to find humor in the situation that has made you angry.After all， it is much healthier to laugh than to get angry.According to the passage， the Oregon University System ().

37. Questions 36 to 40 are based on the following passage.Recognizing when a friend or colleague feels sad， angry or surprised is key to getting along with others.But a new study suggests that being sensitive to people’s feelings may sometimes come with an extra dose of stress.This and other research challenge the prevailing view that emotional intelligence is uniformly beneficial to its bearer.In a study， Psychologist Myriam Bechtoldt of the Frankfurt School of Finance and Management in Germany asked 166 male university students a series of question to measure their emotional intelligence.For example， they showed the students photographs of people’s faces and ask them to what extent feelings such as happiness or disgust were being expressed.The students then had to give job talks in front of judges who displayed serious facial expressions.The scientists measured concentrations of stress hormones in the students’ saliva (唾液)before and after the talk.In students who were rated more emotionally intelligent， the stress measures increased more during the experiment and took longer to go back to baseline.The findings suggest that some people may be too emotionally clever for their own good， says Bechtoldt.“Sometimes you can be so good at something that it causes trouble，” she notes.Indeed， the study adds to previous research hinting at a dark side of emotional intelligence.A study published in 2002 in Personality and Individual Differences suggested that emotionally perceptive people might be particularly influenced by feelings of depression and hopelessness.Furthermore， several studies have implied that emotional intelligence can be used to manipulate others for personal gains.
More research is needed to see how exactly the relation between emotional intelligence and stress would play out in women and in people of different ages and education levels.Nevertheless， emotional intelligence is a useful skill to have， as long as you learn to also properly cope with emotions—both others’ and your own， says Bechtoldt.For example， some sensitive individuals may assume responsibility for other people’s sadness or anger， which ultimately stresses them out.Remember， as Bechtoldt says， “you are not responsible for how other people feel.”What was the purpose of psychologist Myriam Bechtoldt’s experiment?

A. 　To define different types of human feelings.

B. 　To assess the impacts of being emotionally clever.

C. 　To demonstrate how to distinguish different feelings.

D. 　To identify gender differences in emotional intelligence.

9、Prices determine how resources are to be used.They are also the means by which products and services that are in limited supply are rationed(定量配给)among buyers.The price system of the United States is a complex network composed of the prices of all the products bought and sold in the economy as well as those of a variety of services， including labor， professional， transportation， and public services.The interrelationships(相互关系)of all these prices make up the “system” of prices.The price of any particular product or service is linked to a broad， complicated system of prices in which everything seems to depend more or less upon everything else.
