In the United States, 30 percent of the adult population has a "weight problem".To many people, the cause is obvious: they eat too much.But scientific evidence does little to support this idea.Going back to the America of the 1910s, we find that people were thinner than today, yet they ate more food.In those days people worked harder physically, walked more, used machines much less and didn't watch television.

Several modem studies, moreover, have shown that fatter people do not eat more on the average than thinner people.In fact, some investigations, such as the 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.

Studies show that slim people are more active than fat people.A study by a research group at Stanford University School of Medicine found the following interesting facts:

The more the men ran, the more body fat they lost.

The more they ran, the greater amount of food they ate.

Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

31.The physical problem that many adult Americans have is that__________.

A) they are too slim

B) they work too hard

C) they are too fat

D) they lose too much body fat

32.According to the article, given 500 adult Americans, __________ people will have a "weight problem".

A) 30

B) 50

C) 100

D) 150

33.Is there any scientific evidence to support that eating too much is the cause of a "weight problem"？

A) Yes, there is plenty of evidence.

B) Of course, there is some evidence to show this is true.

C) There is hardly any scientific evidence to support this.

D) We don't know because the information is not given.

34.In comparison with the adult American population today, the Americans of the 1910s __________.

A) ate more food and had more physical activities

B) ate less food but had more activities

C) ate less food and had less physical exercise

D) had more weight problems

35.Modem scientific researches have reported to us that__________.

A) fat people eat less food and are less active

B) fat people eat more food than slim people and are more active

C) fat people eat more food than slim people but are less active

D) thin people run less, but have greater increase in food intake

Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.

Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:

The more they ran, the greater their increase in food intake.

Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

In education there should be a good balance among the branches of knowledge that con tribute to effective thinking and wise judgement. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of the natural sciences, the social sciences, and the arts but also relative emphasis among the natural sciences themselves. Similarly, we must have a balance between the current and classical knowledge. The attention of the public is continually drawn to new possibilities in scientific fields and the discovery of new knowledge; these should not be allowed to turn our attention away from the sound, established materials that form. the basis of courses for beginners.

According to the passage, the task of education is fairly complicated because ______.

A．the current public school system is too complicated to be understood

B．the public school system has no choice of what to teach

C．it is difficult to decide whether elementary science should be taught in public schools

D．the educators should take care of both ordinary and gifted students

Today, we are beginning to think differently. In the last few years, re search has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence itself. Perhaps most important, there is considerable evidence now which shows the great influence of the environment both on achievement and intelligence. Children with poor home backgrounds not only do less well in their school work and in intelligence tests—a fact which could be explained on genetic grounds—but their performance tends to deteriorate gradually compared with that of their more fortunate classmates. Evidence like this lends support to the view that we have to distinguish between genetic intelligence and observed intelligence. Any deficiency in the appropriate genes will obviously restrict development, no matter how stimulating the environment. But we cannot observe or measure innate intelligence; whereas we can observe and measure the effects of the interaction of whatever is inherited with whatever stimulation has been received from the environment. Changes may occur in our observations or measurements, if the environment is changed. In other words, the Intelligence Quotient is not constant.

Researches over the past decade have been investigating what happens in this interaction. Work in this country has shown that parental interest and encouragement are more important than the material circumstances of the home.

Two major findings have emerged from these studies. Firstly, that the greater part of the development of observed intelligence occurs in the earliest years of life. 50 percent of measurable intelligence at age 17 is already predictable by the age of four. In other words, deprivation in the first four or five years of life can have greater consequences than any of the following twelve or so years.

Secondly, the most important factors in the environment are language and psychological aspects of the parent-child relationship. Much of the difference in measured intelligence between "privileged" and "disadvantaged" children may be due to the latter's lack of appropriate verbal stimulation and the poverty of their perceptional experiences.

These research findings have led to a revision in our understanding of the nature of intelligence. Instead of it being some largely inherited fixed power of the mind, we now sec it as a set of developed skills with which a person copes with any environment. These skills have to be learned and, indeed, the fundamental one is learning how to learn.

Which of the following might serve as a suitable title for the passage？

A．Intelligence: A Changed View

B．Intelligence and Intelligence Quotient

C．Genetic Intelligence vs Observed Intelligence

D．Innate Intelligence and Developed Skills

Some friendly relationships can be kept on despite argument or heated discussion, but it is usual for close friends to have similar ideas, beliefs, attitudes, and interests. In fact, close friends may sometimes talk about "being on the same wavelength". It generally takes time to reach this point. And the more intimately involved people become, the more they rely on each other, People want to do friends favors and hate to break a promise. Equally, friends have to learn to put up with any annoying habits and to tolerate differences of opinion.

In contrast with marriage, there are no government-sanctioned friendship ceremonies to strengthen the association between two people. But the support and understanding of each other that result from shared experiences and emotions do seem to create a powerful bond, which can overcome difference in background, and thus break down barriers of age, class, or race.

According to the author, ______.

A．all those who get on well with each other are friends

B．friends are closer than people who just get on well with each other

C．everyone understands clearly how to make friends

D．every student has six friends
