In the past fifty years, American society has changed a great deal. Fifty years ago, most
Americans lived in small communities. They rarely moved from one area to another and knew their neighbors at least by name if not by close, personal relations. Life was so personal in those days that people often joked about it.They said that a person could not even stay home from church on Sunday without the whole town knowing about it. It was difficult to keep one's secret in a small community like that, but there was usually a sense of safety, of belonging, and of community togetherness in such places. Except for church and the local movie theater, there was not much entertainment. Some people dreamed about moving to the exciting life of the big cities, but most people were happy to live all their lives in the same community.

Few people experience this type of lifelong relationship or sense of community togetherness now. The American society is much more unsettled now; people often move from neighborhood to neighborhood, city to city, and coast to coast. It is rare to find people who have lived all their lives in one community. Because people move so frequently, they do not have a chance to get to know their neighbors. Perhaps this is also why Americans tend to have a more casual attitude about friendships than people from some other cultures; Americans are accustomed to leaving friends and making new friends. In such an impersonal society, people have lost the habit of saying hello to people they pass on the streets or in the hallways of their apartment buildings.

What is described in the first paragraph?

A.Entertainment in small towns.

B.Americans' adjustment to a moving society.

C.The life style. of Americans in the past.

D.Personal relations in small communities.

"In the long run," as John Maynard Keynes observed, "we are all dead. " True. But can the【

And now, with the growth of【6】knowledge that has marked the past few decades, a few researchers believe it might be within【7】.

To think about the question, it is important to understand why organisms-people【8】-age in the first place. People are like machines: they【9】That much is obvious.

Are you superstitious? No, of course not. Do you believe in magic (魔法), and luck charms

Are you superstitious? No, of course not. Do you believe in magic (魔法), and luck charms (护身符), and elves or gremlins (小精灵) ? Certainly not, but if I should greet you with the usual How's business?" You'll answer "Oh, just so-so" although your business is profiting greatly. When you are successful in some venture you might say you were just lucky. And yet, you know it was probably due to your a bility and hard work. Why? Sometimes you knock on wood because wood was once a tree and there is a primitive belief that protective gods inhabit trees and knocking on wood attracts their attention so they may be credited with your successes.

If I should sneeze, only the strongest of you could refrain(克制而不) from saying "God bless you". Why bless this unsanitary (不讲究卫生的) habit? Our ancestors believed that a sneeze opened the body to invasion by devils, and invoking (召唤) the name of God made the devils get out in a hurry. You may not realize it, but you express this same "devil invasion" when you say, "Whatever can have gotten into that child?" or "I wonder what possessed me to do that?"

Although they may no longer be believed, evidences of superstitions that have had their origins in the primitive fear of the unknown still exist in modern language and gestures.

The author ______.

A.believe that most people are superstitious

B.believe that very few people are superstitious

C.believes that there are still some evidences of superstitions in what we say and what we do

D.is superstitious

The past few years have been busy ones for human-rights organisations. In prosecuting the
so-called war on terror, many governments in Western countries where freedoms seemed secure have been tempted to nibble away at them, while doughty campaigners such as Amnesty International(国际特殊组织) also exist for defence. Yet Amnesty no longer makes the splash it used to in the rich world. The organisation is as vocal as it ever was. But some years ago it decided to dilute a traditional focus on political rights by mixing in a new category called social and economic rights.

You might suppose that the more of rights you campaign for the better. Why not add pressing social and economic concerns to stuffy old political rights such as free speech and free elections? What use is a vote if you are starving? Are not access to jobs, housing, health care and food basic rights too? No: few rights are truly universal, and letting them multiply weakens them.

Food, jobs and housing are certainly necessities, but there's no use to call them "rights". When a government looks someone up without a fair trial, the victim, perpetrator and remedy are pretty clear. This clarity seldom applies to social and economic "rights". Who should be educated in which subjects for how long at what cost in taxpayers' money is a political question best settled at the ballot box(投票箱). And no economic system known to man guarantees a proper job for everyone all the time.

It is hardly an accident that the countries keenest to use the language of social and economic rights tend to be those that show least respect for rights of the traditional sort. And it could not be further from the truth. For people in the poor world, as for people everywhere, the most reliable method yet invented to ensure that governments provide people with social and economic necessities are called politics. That is why the rights that make open polities possible—free speech, due process, protection from arbitrary punishment—are so precious. Insisting on their enforcement is worth more than any number of grandiloquent but unenforceable declarations demanding jobs, education and housing for all.

Many do-gooding outfits suffer from having too broad a focus and too narrow a base. Amnesty used to appeal to people of all political persuasions and none, and concentrate on a hard core of well-defined basic liberties. However, by trying in recent years to borrow moral authority from the campaigns and leaders of the past and lend it to the cause of social reform, Amnesty has succeeded only in muffling what was once its central message, at the very moment when governments in the West need to hear it again.

The human-rights organizations are no longer so influential in that ______

A.freedom has been realized in most countries.

B.they have changed their traditional goals.

C.social and economic rights are more important than political ones.

D.western governments prevent them from speaking out.
