1. Passage Twenty-Four Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas， more disagreements in interest， and more groups and organizations with different beliefs. In addition， there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways， there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory， they are at least customary and undisputed. Within a society， social changes is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material， for example， in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements. Furthermore， social change is easier if it is gradual. For example， it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies ( 一分为二). This is one reason why change has not come more quickly to Black American as compared to other American minorities， because of the sharp difference in “appearance between them and their white counterparts” . The passage has mainly discussed ( ) .

A. the necessity of social change

B. certain factors that determine the ease with which social changes occur

C. two different societies

D. certain factors that promote social change

5. Passage Fifteen Big data can be defined as information that is too big or complex to be contained or processed by any one machine or person. As a student at the University of Sussex， Julian Dailly had two majors——English and philosophy. When he completed his studies， Dailly wondered how he would ever earn a living in a world filled with machines and technology. Now， he is part of the big data industry that includes Google and Facebook. Dailly’s research company， Morar Consulting， started three years ago with five employees. The company’s earnings have increased by 25% each year. It now employs 90 people. “What we do here is we try to discover what’s meaningful for people and link that to their economic behavior，” Dailly said. He noted the importance of working with people with different skills. “We have people from traditional research backgrounds， in addition to some in social sciences， economics， people from tech backgrounds， and salespeople，” Dailly said. Companies like Dailly’s employ recent college graduates. The industry profits from the ideas of these young men and women. New forms of data also make it possible for some observers to predict the future. They are more valuable to companies than the traditional forms of data recording or reporting. “We have access to the core information inside people’s heads，” Dailly said， “They tell you what people are going to do as opposed to what they’ve done. That helps people take proper action in advance. This makes it much more useful for strategy.” Julian Dailly dismisses concerns that computers have finally taken control of our daily lives. “Some may worry that humans will be allowed to be replaced by machines. I think it’s a fantasy.” According to Dailly， the idea that humans may be replaced by machines ( ) .

A. is a wise warning

B. is pure imagination

C. may come true

D. needs further study

3. . Passage Twenty All friendships require a certain amount of chemistry. But when two people of the opposite sex become friends， sometimes those friendly feelings can start to resemble something more like sexual tension. Male-female friendships can be an emotional minefield of hidden desires. Does this mean you secretly want to jump into bed with all of your friends? Of course not. But do you ever wonder how many of them might be interested if the opportunity presented itself? Maybe you and your platonic (柏拉图式的) friendship are just a bad breakup and a bottle of wine away from crossing that boundary and hooking up (结合). So can two people of the opposite sex ever really be “just friends?” The Hollywood answer to this age-old question is a decisive HELL NO. On screen， male-female friendships always turn into something more. Harry and Sally， Chandler and Monica， Jim and Pam … … Do I need to go on? Even the characters in Just Friends wind up becoming much more than the film’s definitive title suggests. Cinematic stories dictate that when reasonably attractive men and women befriend one another， they are always on the road to romance， whether they realize it or not. But how much truth is there to this friendship as foreplay theory? It is not a whole lot. Real life isn’t a romantic comedy. Men and women go to school together， work together and hang out in plenty of platonic settings without falling hopelessly in love with one another. Last year， a close female friend of mine moved in with a new male roommate. My immediate reaction was， “You two are definitely going to sleep together.” It seemed to me that a single man and woman living under the same roof would inevitably end up doing it. Much to my surprise， the roommate romance never happened. Almost one year later， the two of them have never even come close to seeing each other naked. Instead， their way of life has come to resemble a sexless marriage. They cook for each other， argue over domestic chores and insist that they never， ever think about each other “that way.” In the movie Just Friends， the two leading characters ( ) .

A. are just friends

B. have romance

C. don’t realize their true relationship

D. can never be friends again

2. Passage Thirteen Trees are useful to man in three important ways: they provide him with wood and other products; they give him shade; and they help to prevent droughts and floods. Unfortunately， in many parts of the world， man has not realized that the third of these services is the most important. In his eagerness to make money from trees， he has cut them down in large numbers， only to find that without them he has lost the best friends he had. And besides， he is usually too careless to plant and look after new trees. So the forests slowly disappear. This does not only mean that man will have fewer trees. The results are even more serious: for where there are trees， their roots break up soil——allowing the rain to sink in——and also bind the soil， thus preventing it from being washed away easily; but where there are no trees， the rain falls on hard ground and flows away， causing floods and carrying away the rich top-soil. When all the top-soil is gone， nothing remains but worthless desert. Two thousand years ago a rich and powerful country cut down its trees to build warships， with which to gain itself an empire. It set up the empire but， without its trees， its soil became poor and it grew weak. When the empire fell to pieces， the home country found itself faced with floods and starvation.Why do forests in many parts of the world slowly disappear?

A. New trees are not looked after properly.

B. Many trees have been cut down by man.

C. Man has not paid enough attention to planting trees.

D. All of the above.

5. Passage One There are three separate sources of danger in supplying energy by nuclear power. First， the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built， the containers used for the transport of the materials are not. Normally， only two methods of transport are in use， namely road or rail. Unfortunately， both of these may have an effect on the general public， since they are sure to pass near， or even through， heavily populated areas. Second， there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes nonradioactive， so they must be stored in one of the inconvenient ways that scientists have invented. For example， they may be buried under the ground， or dropped into deserted mines， or sunk in the sea. However， these methods do not solve the problem， since an earthquake could easily break the containers.
Third， there may occur the danger of a leak or an explosion at the power station. Compared with the other two dangers， this is not very likely， so it does not provide a serious objection to the nuclear program. However， it can happen. Separately， these three types of dangers are not a great cause for worry. Taken together， though， the probability of disaster is extremely high. Which of the following is TRUE?

A. The public are not strongly against the nuclear program.

B. The public are strongly against the nuclear program.

C. The public are not worrying about the dangers of unclear power.

D. The public know little about the dangers of unclear power.

43. The factory is trying every means to (_____)_ the wholesale price of its products.

A. 　pull down

B. 　 bring down

C. 　 put down

D. 　 set down

D. The power station is a safe place.

4. Passage Five The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example， some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money. Sometimes advertising is intentionally misleading. A few years ago， a brand of bread was offered to dieters with the message that there were fewer calories in every slice. It turned out that the bread was not dietetic， but just regular bread. There were fewer calories because it was sliced very thin， but there were the same number of calories in every loaf. On the positive side， emotional appeals may respond to a consumer’s real concerns. Consider fire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as the message in the ads， they will benefit from the advertising. Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it? Advertising is intended to appeal to consumers， but it does not force them to buy the product. Consumers still control the final buying decision. It can be inferred from the passage that a smart consumer should ( ) .

A. think carefully about the benefits described in the advertisements

B. guard against the deceiving nature of advertisements

C. be familiar with various advertising strategies

D. avoid buying products that have strong emotional appeal
