In order to solve the pollution problems that began from the mid-20th century, a number of environmental protection organizations have formed. However, the most important pollution fighter is perhaps each individual person. If everyone makes the effort, pollution can be greatly reduced,

In a way, some pollution can be controlled in daily life. For example, solid wastes are a major cause of land pollution, but many wastes, such as empty cans, glass bottles, old car tires and newspapers, can be recycled. Some places pay people to bring in used goods for recycling. Moreover, one major factor in air pollution is that many people use cars needlessly. So public transportation, bicycles, and walking are all good choices to prevent pollution.

　　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 the 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 modern studies, moreover, have shown that fatter people do not eat more on

　　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 run, the more body fat they lost. The more they ran, the greater amount

　　of food they ate. Thus, those who run the most ate the most, yet lost the greatest amount of

　　body fat.

　　11. 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

　　12. According to the article, given 500 adult Americans, ________ will have a weight

　　problem.

　　13. 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 that.

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

　　14. 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

　　15. Modern scientific researchers have reported to us that ________.

　　Today anyone will accept money in exchange for goods and services. People use

　　money to buy food, furniture, books, bicycles and hundreds of others they need or want.

　　When they work, they usually get paid in money.

　　Most of the money today is made of metal pr paper. But people used to use all kinds

　　of things as money. One of the first kinds of money was shells. Shells were not the only

　　things used as money. In China, cloth and knives were used. In the Philippine Islands, rice

　　was used as money. In parts of Africa, cattle were one of the earliest money. Other animals

　　were used as money too.

　　The first metal coins were made in China. They were round and had a square hole in

　　the center. People strung them together and carried them from place to place. Different

　　countries have used different metals and designs for their money. The first coins in

　　England were made of tin. Sweden and Russia used copper to make their money. Later,

　　other countries began to make coins of gold and silver.

　　But even gold and silver were inconvenient if you had to buy something expensive.

　　Again the Chinese thought of a way to improve money. They began to use paper money.

　　The first paper money looked more like a note from one person to another than paper

　　money used today.

　　Money has had an interesting history from the days of shell money until today.

　　1. Which of the following can be cited as an example of the use of money in exchange for

　　services？

　　A. To sell a bicycle for $20.

　　B. To get some money for old books at a garage sale.

　　C. To buy things you need or want.

　　D. To get paid for your work.

　　2. Where were shells used as money in history？

　　A. In the Philippines. B. In China.

　　C. In Africa. D. We don’t know.

　　3. Why did ancient Chinese coins have a square hole in the center？

　　A. Because it would be easier to put them together and carry them around.

　　B. Because it would be lighter for people to carry from place to place.

　　C. Because people wanted to make it look nicer.

　　D. Because people wanted to save the expensive metal they were made from.

　　4. Why does the author say that even gold and silver were inconvenient if you had to buy

　　something expensive？

　　A. Because they are difficult for people to obtain.

　　B. Because they themselves are expensive, too.

　　C. Because they are not easy to carry around.

　　D. Because they are easy to steal.
