1970 was “World Conservation(保护) Year”. The United Nations wanted everyone to know that the world is at risk(危险).They hoped that people would do something quickly to conserve nature.

Here is one example of the problem. At one time there were 1,300 plants, trees and flowers in Holland, but now only 860 are existing. The others have been destroyed by modern man and his technology.

Here is another example. In 1620, about half the USA was covered by forests. In 1850, about a third was covered by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand. Today too many trees are still being cut down.

We’re changing the earth, the air and water. We can’t live without these things. If we go on like this, we shall destroy ourselves. A lot of people know that conservation is necessary. Many things have been done to save our world. For example, people plant more and more trees on the hills. In a small town in the USA a large group of girls cleaned the banks of 11 kilometers of their river. Young people may hear about conservation through a record by the name of NO ONE’S GOING TO CHANGE OUR WORLD. It was made by Scales, Cliff Richard and other singers. The money from it will help to conserve wild plants and animals. In China, a new Great Wall has been built across the northern part of the country to stop the sand from moving towards the rich farmland in the south.

China now has 380 million smokers - about one third of the world total. Chinese smokes now become addicted to nicotine (尼古丁) at the age of 19, five years earlier than the average starting age of24 in 1997.

Of the 1.1 billion smokers all over the world, more than 800 million are in developing countries. And as the world's largest developing country, China also has the largest number of smokers.

Some frightening facts start to appear when we examine who China's smokers are. Of the 380 million addicts, more than 100 million are under the age of 18, while more than 50 percent Of male teachers and doctors are smokers.

Such a high rate of addicts among male teachers and doctors will certainly have a bad impact on the young generation. Teachers are usually expected to be role models for students who tend to consider whatever they do is right and follow their example. It is very likely that the number of teenage smokers will increase in the near future unless measures are taken to stop teachers from smoking in front of their students or designate(指出)schools as non-smoking zones(区域)。

What is truly puzzling is why so many doctors smoke. They are aware of the results of the habit, such as high blood pressure and lung cancer. Their example only helps to make addiction of so many others seem normal.

If educated people set an example by stopping at least in public places, it would be much easier to tell people that it is uncivilized(不文明的)to smoke in public places.

In China, there should also be a national law to ban(禁止)smoking in public places. These

would make a great contribution to cutting the number of people in China who are smoking

themselves into an early grave(坟墓).

57. In developing countries, China has the largest number of smokers, which covers_______.

58. In the writer's opinion, who or what has a bad effect on young smokers, especially those under 18?

A. Parents.                             B. Teachers only.

C. Advertisements.                        D. Teachers and Doctors.

59. Which of the following statements is NOT true according to the text?

A. In China, those who get into the habit of smoking seem to be younger and younger.

B. More than half of teachers and doctors are smokers in China.

C. The writer suggests schools should be designated as non-smoking zones.

D. It is of a great help to ban smoking in public places.

60. What does the underlined word "addicts" in the third paragraph mean?
