Is there any truth to this story?Jane Leon, New York, U
2、SADear Ms. Leon,Well, a lot of research is being conducted in this area, but so far, the brain scanning equipment and corresponding computer programs havent been able to actually read thoughts. In one experiment, test subjects(受试者)were connected to scanning equipment and shown two numbers on a scree
3、n. They were then asked to choose between adding or subtracting(减)the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions(假设)70 percent of the time. Its not quite mind reading, but its certainly a first step.Dr. J.Dear Dr. Jeffers, My thre
4、e-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldnt do it. Why not?Glenn Lewis, Vancouver, CanadaDear Mr. Lewis,Its because of how the brain works. The brain is trained to
5、know what to pay attention to and what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic reaction when there is an unexpected feeling. For example, you dont notice how your shoulder feels while youre walking down the street. But if someone comes up b
6、ehind you and touches you lightly on the shoulder, you may jump in fear. Its that unexpected part that causes the tickle reaction.Dr. J.1. What can we learn from the answer to the first question?

8、D. Dr. Jeffers4. According to the text, Jeffers is probably _. A. a computer programmer B. a test subjectC. a human brain expert D. a medical doctorBAlthough the US is so big and its people have so many different racial backgrounds, it is in some ways less varied than Europe. The English language is
9、 used almost everywhere in its American form. The American way of speaking has developed independently of English and is on the whole closer to what can be heard in Ireland. Another instance of uniformity(一致) is in habits and ways of living. From Boston to Los Angeles it is as far as from France to
10、Central Asia, and from east to west there are five time zones; but everywhere people get up and go to bed at about the same time, eat the same kind of food, buy in the same kind of shops, work and rest at the same time of the day and have the same pattern of holidays. In most of the things that matt
11、er there is less difference between rich people and ordinary people or between town and country, than in any single European nation. Although the United States desires so much land and the land produces far more food than the present population needs, its people are by now almost entirely an urban s
12、ociety. Less than a tenth of the people are engaged in agriculture and most of the rest live in or around towns large and small. Here the traditional picture is changing; most Americans do not live in small towns any more. Half the population now live in some thirty metropolitan(大城市的) areas. The fac
13、t that the United States has always been a single economic unit has contributed to uniformity. Modern industry favors large organization, and it is no accident that the worlds biggest commercial firms are American. The people can choose between the products of competing manufacturers but the product
14、s are all much alike.5.

The underlined part “In most of the things that matter” means .A. in most basic things such as food, clothing and housesB. in the more exp
17、ensive things such as cars, TV sets, etcC. in their land, housing and bank savingsD. in their wealth and income完形填空:I have to admit, when I watch television, I rarely watch commercials.
