Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.

Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.

Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.

One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs.

A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year –olds who had watched lots of  TV during childhood .But the results don’t prove that TV is the cause and  don't ride out that already poorly motivated youngsters(年輕人）may watch lots of TV.

Their study measured the TV habits of 26-year-olds between ages 5 and 15. These with college degrees had watched an average of less than two hours of TV per     weeknight during childhood, compared with an average of more than 2 1/2 hours for those who had no education beyond high school

In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest

While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn't have TVs in their bedrooms

According to the California study, the low-scoring group might        .

A. have watched a lot of TV        B. not be interested in math

C. be unable to go to college        D. have had computers in their bedrooms

What can we learn from the last two paragraphs?

A. More time should be spent on computers.

B. Children should be forbidden from watching TV.

C. TV sets shouldn't be allowed in children's bedrooms.

D. Further studies on high-achieving students should be done.

What would be the best title for the text?

A. Computers or Television.            

B. Effects of Television on Children.

C. Studies on TV and College Education.

D. Television and Children's Learning Habits

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

I worked for a short time as a cashier（出納員）at a restaurant a few months ago. 71  One night, just before Christmas, I found a large black wallet on the floor near one of the tables. I guess I should have checked it to find out who was the owner, but I was busy at the time. Also, I imagined that if the wallet contained anything valuable, the owner would be back.

An hour later a man came up to the counter（柜臺(tái)）. 72  I asked him to describe the lost wallet, and after he described it exactly, I gave him the wallet. He expressed his sincere thanks when I handed it to him. He asked me if I had opened it, and when I told him “ No”, he opened it right away and showed that it contained nearly $800 in cash (現(xiàn)金). 73  

“A reward for your honesty,” he said and then turned and walked away.

74  I began wondering whether I would have been so honest if I had known what was in the wallet! I thought that if there had been no way to find the owner and no one had returned to claim（認(rèn)領(lǐng)）it, I might have kept it. But it also came into my mind that I had in fact saved someone’s Christmas plans by finding and returning the wallet. 75  The good feeling it gave me was worth more than anything money could  buy.

A. He looked quite worried and asked if anyone had found a wallet.

B. Later I thought about it again.

C. To my surprise, he took out a twenty–dollar bill and handed it to me.

D. So I didn’t return the wallet until the owner returned.

E. I wanted to be honest, so I didn’t care much about money.

F. I also helped clear off the tables when it was especially busy.

G. For quite a long time I kept happy whenever I thought about it.
