A new report says sea ice in the Arctic Ocean is melting more quickly than expected. American scientists say the ice is melting even faster than computer programs had estimated.
Scientists know that climate change has a major effect on the Arctic Ocean partly because sea ice is disappearing. They also know that areas of open seawater are expanding. Such areas are known to take in sunlight and increase temperatures. Scientists say this has helped to cause the loss of the Arctic’s ice cover.
For the study, the American scientists compared eighteen computer programs with observations made by satellites and other instruments. The Intergovernmental Panel on Climate Change used the computer programs to prepare its 2007 estimates of climate change.
The computer programs gave estimates of the amount of ice in the Arctic Ocean in the month of September. September is when the Arctic has the least ice, after the warm, summer months. The computer estimates suggested an ice loss of two and a half percent for every ten-year period between 1953 and 2006.
Newer studies of the Arctic have used information gathered by aircraft, satellites and ships. This information showed a loss of September ice cover of almost eight percent for every ten-year period between 1953 and last year. This means the ice is disappearing about thirty years faster than the computer programs estimated.
The scientists say the programs might not have recognized the full effect of increased carbon dioxide and other gases in Earth’s atmosphere. They say their study suggests the gases may have more of an effect than had been thought.

It is only during the last few years that man has generally realized that in the world of nature a balance exists between all forms of life. No living thing can exist by itself: it is a part of a system (体系) in which all forms of life are joined together. If we change one part of the natural order, this will in its turn almost certainly bring about changes in some other part.
The cutting down of forests reduces the supply of oxygen. The killing of weeds and insects by chemicals leads to the wide spread poisoning of animals and birds. The throwing of waste products into the ocean harm to life in the sea, while waste gases change the chemical balance of the atmosphere.
And so we could go on, adding more examples, until in despair (绝望) we might feel like giving up the struggle to control and keep within limits these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but not so clever at looking far ahead, or at thinking about what the future results of his action might be.
1.The first paragraph mainly tells us that __________.
A. everything in nature can’t exist without the help of human beings

D. man has well known the importance of the balance for a long time
2.The examples given in the second paragraph are used to prove that __________.
A. it is very important to protect forests
B. there are some living things which can exist all by themselves without change
C. all forms of life belong to a system in which all the part can be changed for one another
D. we cannot change one form of life or matter without disturbing (扰乱) the balance of nature
3.In the second paragraph the underlined word “atmosphere” means __________.
A. the production of chemical factories B. the gas in the outer space
C. the mixture of gases that surrounds the earth D. the health of the human body
4.The third paragraph suggests that __________.
A. man shouldn’t think only about his immediate needs without enough thought on the future results
B. man is very clever in planning his distant future
C. man often feels that he has to give up in despair
D. man is always anxious to control and keep his actives within limits
My husband and children think they are very lucky that they are living and that it’s Christmas again. They can’t see that we live on a dirty street in a dirty house among people who aren’t much good. But Johnny and children can’t see this. What a pity it is that our neighbours have to make happiness out of all this dirt. I decided that my children must get out of this. The money that we’ve saved isn’t nearly enough.
The McGaritys have money but they are so proud. They look down upon the poor. The McGarity girl just yesterday stood out there in the street eating from a bag of candy(糖果)while a ring of hungry children watched her. I saw those children looking at her and crying in their hearts; and when she couldn’t eat any more she threw the rest down the sewer(下水道). Why, is it only because they have money ? There is more to happiness than money in the world, isn’t there?
Miss Jackson who teaches at the Settlement House isn’t rich, but she knows things. She understands people. Her eyes look straight into yours when she talks with you. She can read your mind. I’d like to see the children be like Miss Jackson when they grow up.
