　　If you travel by air across the center of Africa or South America, you fly over forests for thousands of kilometers．These great forests are the oceans of trees．There are thousands and thousands of different kinds of plants and animals there．

　　However, the world’s forests are getting smaller all the time．We are cutting down the trees because we need wood, and we need more farmland．Some people say that there will not be any forests like these in 20 or 30 years．What will happen if they disappear?If we cut down our forests, a lot of plants and animals will disappear from the world．In a lot of places the new farmland will soon look like the old deserts．

　　Crops will not grow there．It will not rain very often, and the weather will get very hot．Perhaps the climate of the world will change．This will be dangerous for everyone in the world．That is why we must take care of our forests．

Lead（鉛） deposits, which accumulated（增加） in soil and snow during the 1960's and 70's, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated（托管） unleaded gas use in the United States, the lead accumulation world-wide has decreased greatly.
A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北極的) snow were declining（減少）.
In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasoline and thus enabled scientists to differentiate (分區(qū)) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.
In a study published in the journal Ambio, scientists found that lead levels in soil in the North-eastern United States had decreased markedly since the introduction of unleaded gasoline. Many scientists had believed that the lead would stay in soil and snow for a longer period.
The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed (再分配)the lead faster than the scientists had expected. Scientists say both studies show that certain parts of the ecosystem (生態(tài)系統(tǒng) ) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.
1. The study published in the journal Nature indicates that ________.
A. the Clean Air Act has not produced the desired results
B. lead deposits in arctic snow are on the increase
C. lead will stay in soil and snow longer than expected
D. the US is the major source of lead pollution in arctic snow
2. Lead accumulation worldwide decreased significantly after the use of unleaded gas in the US ________.
A. was discouraged               B. was carried out by law
C. was forbidden by law           D. was introduced
3. How did scientists discover the source of lead pollution in Greenland?
A. By analyzing the data published in journals like Nature and Ambio.
B. By observing the lead accumulations in different parts of the arctic area.
C. By studying the chemical elements of soil and snow in Northeastern America.
D. By comparing the chemical compositions of leaded gasoline used in various countries.
4. The authors of the Ambio study have found that ________.
A forests get rid of lead pollution faster than expected
B. lead accumulations in forests are more difficult to deal with
C. lead deposits are widely distributed in the forests of the US
D. the upper layers of soil in forests are easily polluted by lead emissions
5. It can be inferred from the last paragraph that scientists ________.
A. are puzzled by the mystery of forest pollution
B. feel ease by the use of unleaded gasoline
C. still consider lead pollution a problem
D. lack enough means to combat lead pollution

One reaction to all the concern about tropical deforestation（毀林） is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"

The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.

Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.

Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.

Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.

Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.

Can tropical deforestation affect our everyday lives? Now, you should have got the answer.

1.The underlined word "synthetics" probably means_________.

A. natural rubber                   B. tropical materials

C. man-made material               D. commercial rubber

2.According to the passage, which of the following is NOT true?

A. The forests are losing their function in turning carbon dioxide into oxygen.

B. Many of our daily uses are related to the tropical forests.

C. Tropical plants can be used to make industrial products.

D. High carbon dioxide levels will make the earth warmer.

3.The author's attitude towards the tropical deforestation is _________ .

A. puzzling        B. cold          C. supporting        D. opposed

4.Which of the following might be the best title for the passage?

A. Tropical Forests                 B. The Value of Tropical Forests

C. Tropical Forests and Our Life     D. The Greenhouse Effects
