32、stop the Earths atmosphere from warming is by planting more trees. The idea is that more trees will take in or absorb some of the carbon dioxide in the atmosphere. Carbon dioxide is a gas released by cars, factories and other human activities. The gas traps heat in the Earths atmosphere, which warms

33、 the planet. However, two new studies have found that trees may not be as helpful in reducing carbon dioxide as had been thought. The first study was done at Duke University in Durham, North Carolina. Researchers pumped extra carbon dioxide into a test area where pine trees were growing. The trees g

34、rew 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, such as nitrogen. In the second study, researchers from Duke and Bowdoin College in Brunswick, Maine exami

35、ned the soil 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 released into the atmosphere as carbon dioxide. The findings of the two studies were published last month in Nature magazine. They suggest there is limit

36、ed value in planting trees to reduce the carbon dioxide pollution in the atmosphere. Forest planting has been a part of negotiations on a world agreement to reduce greenhouse gases that scientists believe cause global warming. The United States, Canada, Japan and some other industrial countries have

37、 supported the idea. But this new research suggests the idea is not as effective as environmental activists had thought. Scientist Ram Oren of Duke University led the study on tree growth. He says that earlier estimates on the ability of forests to absorb carbon dioxide were overly hopeful. Some sci

38、entists not involved in the studies say the research provides some of the first evidence on how trees react to carbon dioxide. Other scientists say the research disputes a belief among some coal and power companies. The companies say that rising levels of carbon dioxide in the atmosphere will not cr

39、eate harmful global warming. Instead, they say it will increase forests and other plants. 85 What is the purpose of this passage? （ A） Introduce some new ideas about the relationship between trees and carbon dioxide. （ B） Introduce recent condition of global industrial pollution. （ C） Call on people

40、 to plant more trees to reduce greenhouse gases. （ D） Point out that power companies should be responsible for the rising levels of carbon dioxide. 86 Why researchers put trees in extra carbon dioxide in the first study? （ A） To learn whether trees can still absorb carbon dioxide under extreme condi

41、tions. （ B） To get more oxygen from these trees. （ C） To evaluate the maximum carbon dioxide that trees can absorb. （ D） To see the growth rate of these trees. 87 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）

42、They broke down and the carbon content had mainly turned into carbon dioxide. （ C） They broke down and the carbon content was mainly absorbed in the soil. （ D） They absorbed more carbon dioxide. 88 Scientist Ram Oren is of the opinion that common beliefs of the trees ability to absorb carbon dioxide

43、 are _. （ A） biased （ B） insightful （ C） overoptimistic （ D） totally wrong 89 The word “it“ (Line 7, Para. 6) probably refers to _. （ A） carbon dioxide （ B） nitrogen （ C） atmosphere （ D） coal 89 Theres been a lot of talk about extraterrestrial beings visiting our planet. I dont put much stock in tha

44、t. I am convinced, however, that we are surrounded by sentient things of our own making whose single aim is the harassment of the individual and, ultimately, the destruction of society. Let me illustrate. A couple of years ago, I received a $ 600 insurance dividend. Sitting at the kitchen table, my

45、wife and I discussed what we might do with the bonanza. I realize now that the refrigerator overheard our conversation. The very next day, it went berserk. The repairman told us we needed a new unit. Cost: $ 600. Not long after, we got a refund from the IRS, enough to pay for a vacation in Mexico. “

46、Ive something to tell you,“ I said to my wife. “Privately.“ “How about the den?“ she suggested. I remembered that the color television set is in the den. “No, not there. Lets go outside.“ I showed her the check as we stood in the driveway. We hugged each other elatedly and hardly noticed the rain. M

47、y car was parked within earshot. I didnt think anything of it at the time. As I started for the train the next morning, the car began making devilish screeching sounds. “The engines shot,“ my mechanic said, “Replacing it will cost about a thousand dollars.“ The cars demise convinced me I was on to s

48、omething big. I dug through our financial records. I discovered that over the past ten years our receipt of“ found“ money invariably was followed by equal expenditures to replace a hot-water heater, a television and a stove. Today, I lavish compliments on all the mechanical devices in our home. And

49、I never, ever mention financial rewards in front of them. But if this article is published and Im paid for it, the word processor is going to go wrong for sure. Itll know. 90 In Paragraph 1, “sentient things of our own making“ refer to _. （ A） extraterrestrial beings （ B） human beings （ C） our sense organs （ D） mechanical devices made by man 91 Which of the following s
