activity is the second leading cause of early deaths among adults. The first is smoking. By the time people are eighteen, their lungs are fully developed, or close to it. The doctors say it is impossible to recover from any damage. Researchers say they are still not sure how air pollution affects lung development. They believe that pollution affects the tiny air spaces where oxygen and carbon dioxide (二氧化碳) are
exchanged. Arden Pope is an economics professor at Brigham Young University in Provo, Utah. Professor Pope wrote a commentary about the study. He noted that air quality in Southern California has improved since the study began in the early
nineteen-nineties. Clean-air laws have reduced pollution from vehicles, industry and other causes. But dirty air is still a problem in areas of California and other places. Professor Pope says continued efforts to improve air quality are likely to provide additional improvements in health.
36 A study done by researchers at the University of Southern California indicates that ________.
A. 1,700 children from Southern California have weak lung activities B. children in Southern California use less lung strength to breathe C. air pollution may affect the growth of children's lungs
D. 80 percent of children in Southern California suffer from air pollution 37 According to the article, children living in dirty air
A. may lose eighty percent of their normal lung strength B. may suffer more severe effects from a common cold C. were five times more likely to catch a common cold D. were unlikely to recover from any lung damage

Passage Three
Questions 41 to 45 are based on the following passage:
What makes money valuable? Why is a piece of paper marked $10 worth more than one marked $1? You could say there is no reason. It’s true that a special kind of paper is used to make dollar bills, and they are pretty, but that’s not what makes them valuable. The real reason money is valuable is that everyone believes it is.
Ancient economies had no paper money or coins. Some used barter — trading one thing for another. Others used all kinds of objects as money. Any object would do, as long as there was not an unlimited amount of it. Animals or metals were popular, and so were manufactured products like jewelry or weapons. Wealth in ancient Greece was measured in tools or cattle. This kind of money had two purposes. First, it was useful in itself. Tools and cattle can be used for farming. And second, it was a way to symbolize (象征) and measure value. A house, for example, would be valued at a certain number of tools or cattle. This greatly simplified trade. Other societies used money that was totally symbolic. For instance, American Indians used wampum, which is made from seashells. And until recently on the Pacific island of Yap, people used large stone discs as money.
In most places these types of money died out because more practical forms of money were invented. People started using precious metals, such as gold and silver, that were easier to carry around than tools or stones. And in the eighteenth century, paper money was introduced. At first people were suspicious of the new currency, but they came to accept it because the government or bank issuing it would exchange an equal amount of gold for the paper. A $10 bill really was worth $10 0f gold. But now, people are used to the idea that the government doesn’t have to back its money with gold. Everyone believes that a $10 bill is worth $10 and that is good enough. But if, for some reason, people ever lost faith in paper money, ten dollars wouldn’t be worth the paper it’s printed on.
41 Which of the following in NOT mentioned as the first kind of money?
A. Animals B. Houses C. Metals D. Weapons 42 The pronoun it (line3, para. 2) refers to __________.
A. money B. wealth C. farm work D. the object chosen as money 43 Tools and cattle were used as money because __________. A. they could be found in every family B. they were useful and symbolized value C. they were easier to carry around
D. they were the only wealth in ancient times
44 The word ―precious‖ (line2, para.3) is closest in meaning to __________. A. valuable B. popular C. Large D. heavy
14
45 People were suspicious of paper money most probably because __________. A. paper is not as useful as tools B. paper had no value of its own
C. paper was just invented and new to people D. paper was under the control of the government
