Scientists have long believed one way to stop the Earth’s air from warming is by planting more trees. The idea is that more trees will take in or absorb(吸收) some of the CO2 in the air. CO2 is a gas released by cars, factories and other human activities. The gas traps heat in the Earth’s air, which warms the planet. However, two new studies have found that trees may not be as helpful in reducing CO2 as thought.

The first study was done at Duke University in Durham, North Carolina. Researchers pumped(打气) extra CO2 into a test area where green trees were growing. The trees grew thirty-four percent faster during the first three years. However, in time, the trees slowed to about their normal growth rate. The scientists say this is because trees need other nutrients(营养素), such as nitrogen(氮).

In the second study, researchers from Duke and Bowdoin College in Brunswick, Maine examined the soil(泥土) around trees. They discovered that as the leaves broke down into the soil, all the carbon was not trapped in the soil. Much of it was let into the air as CO2.

The findings of the two studies were published last month in Nature magazine. They suggest there is limited(有限的) value in planting trees to reduce the CO2 pollution in the air.

Forest planting has been a part of negotiations(谈判) on a world agreement to reduce greenhouse gases that scientists believe cause global warming. The United States, Canada, Japan and some other countries have supported the idea. But this new research suggests the idea is not as effective as environmental activists(积极分子) had thought. Scientist Ram Oren of Duke University led the study on tree growth. He says that earlier estimates(估计) on the ability of forests to absorb CO2 were overly hopeful.

Some other scientists say the research provides some of the first evidence on how trees react(反应) to CO2. Some other scientists say the research disputes(质疑) a belief among some coal and power companies. The companies say that more CO2 in the air will not create harmful global warming. Instead, they say it will increase forests and other plants.

1.Why did the researchers put trees in extra CO2 in the first study?

A. To learn whether trees can still absorb CO2 under extreme conditions.

B. To get more oxygen from these trees.

C. To know how much CO2 that trees can absorb.

D. To see the effect of CO2 on the growth rate of these trees.

2.What happened to the leaves falling from the trees in the second study?

A. They broke down and the main parts turned into oxygen.

B. They broke down and the carbon had mainly turned into CO2.

C. They broke down and the carbon was mainly absorbed in the soil.

D. They absorbed more CO2.

3.Scientist Ram Oren thinks that common beliefs of the tree’s ability to absorb CO2 are __________.

A. just right　　 　　　　 B. not acceptable

C. a bit too cheerful　 D. too dangerous

________ planting trees.

九年级英语补全对话中等难度题查看答案及解析

The trees have been on the earth for millions of years. 1. Disease(疾病) is destroying trees. For example, in the 1970s, many trees in Europe were killed by disease.

2. This new danger attacks all the forests and woods of Europe from northern Sweden to southern Italy. First the branches turn yellow and brown. Then the trees’ leaves fall. The roots and the trunk shrink(萎缩). Finally the trees die. In the Black Forest in southern Germany, 75％of the trees have been destroyed or killed．

3. Nobody knows exactly, but it is probably air pollution or acid rain(酸雨). Factories, power stations and cars give off tons of smoke with acid into the air. Sunlight turns these into something harmful which fall with rain or snow onto the trees.

What can be done about acid rain?　 4.

Acid rain doesn’t always fall on the countries which produce the pollution. The wind carries it from one country to another. Badly, the governments don’ t want to spend money on it if it won’ t harm the trees in their own countries.

5. The rainforests of Asia and South America are being cut down for firewood and building materials. Something must be done. If the trees die, we will, too.

根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺，内容完整。

A. What is killing the trees?

B. But today trees are in great danger.

C. Trees are also killed by people.

D. Now an even greater danger is destroying trees.

E. Why don’t the governments do something to save the trees?
