Many disease researchers have warned that rising global temperatures could lead to more diseases. for example by allowing tropical diseases to expand their ranges into what are now mild regions. This is a particular fear for the diseases carried by insects such as malariac(疟疾） and
sleeping sickness.
But the reality is more complex, argues Kevin Lafferty. a disease ecologist. He argues that a warming climate could favour some diseases in certain regions while controlling them in others.
Lafferty does not deny that climate change might allow malarial mosquitoes to spread to new areas. However he believes that hotter and drier conditions may also get rid of mosquitoes from areas where they currently exist. If this were the case, he says. there would be little. if any, net
increase (净增长） in the risk of disease.
In addition, many mild regions such as southern Europe or the southern U.S. have good sanitation（卫生设备） and insect control programmes which, Lafferty says, would prevent diseases from becoming common even if climatic conditions were suitable.
Finally, he argues, climate change could wipe many species off the plant. Infectious pathogens（病原体） depend on their hosts for survival so they too may become endangered-especially if they,like malaria, rely on more than one host.
But Mercedes Pascual of the University of Michigan points out that there are large human populations in the east African highlands, just outside of the existing range of malarial mosquitoes.She said as temperatures rise, the mosquitoes will reach these areas. So the disadvantages will
outweigh the advantages of decreased risk elsewhere.
Most of the ecologists do, however, seem to agree on one point: predicting where a disease is going to go next involves far more than just considering climate. No matter what the results of the debate are, they all agree that health concerns should continue to play a critical role in climate policy and the debate shouldn't be regarded as weakening the case for action against global warming.

A. will not increase the spread of insect-bome diseases
B. may not significantly increase the risk of disease in the whole world
C. will not affect the dry regions where sanitation is good

B. when making a climate policy one should take health into account
C. the debate mentioned in the passage furthers the debate on global warming
D. a policy should be made immediately to try to stop climate change

B. nothing can be done to stop the present global warming
C. scientists have found ways to stop the wild spread of disease
D. ecologists have different views on whether the global warming will spread diseases further
There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the assumption that drama came from ritual (宗教仪式). The argument for this view goes as follows. In the beginning, human beings viewed the natural forces of the world, even the seasonal changes, as unpredictable, and they sought through various means, to control these unknown and feared powers. Those measures which appeared to bring the desired results were then kept and repeated until they hardened into fixed rituals. Eventually stories arose which explained the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths (神话), coutinued to exist and provided material for art and drama.
Those who believe that drama came from ritual also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used. Furthermore, a suitable site had to be provided for performances and when the entire community did not participate, a clear division was usually made between the “acting area” and the “watching area.” In addition, there were performers, and, since considerable importance was attached to avoiding mistakes in performing, religious leaders usually undertook that task. Wearing masks and costumes, they often imitated other people, animals, or supernatural beings, and used gestures about the desired effect, success in hunt or battle, the coming rain, the revival (复活) of the Sun. Eventually such dramatic representations were separated from religious activities.
Another theory traces the theater’s origin from the human interest in storytelling. According to this view, tales about the hunt, war, or other feats are gradually added in detail, at first through imitation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely-related theory traces theater to those dances that are primarily rhythmical and gymnastic or that are imitations of animal movements and sounds.What does the passage mainly discuss?

One kilogram——that was all it took to crown（给……加冕） the world's strongest man.
German weightlifter Matthias Steiner pulled ahead of Russian rival Evgeny Chigishev to win the Olympic men's +105 kg weightlifting gold medal on Tuesday.
Steiner lifted a total of 461kg, 203kg in the snatch(抓举) and 258kg in the clean and jerk(挺举), to beat Chigishev by a single kilogram. The German won the battle of giants in his last lift, winning his country's first gold medal in the event at this year's Games.
Steiner's winning lift was also the last effort of the sport for this Olympics at which China earned eight of the 15 golds.
Steiner was born in Austria and represented his country of birth at the Athens Olympics four years ago, placing seventh in the lower 105kg category, but had a falling out with Austria's weightlifting federation afterwards.
He applied for German citizenship in 2005 and got married, but his career went into deep freeze（困境）as he could not compete without a passport. He finally obtained the document last January.
The German, who turns 26 on Monday, had come to these Games on a mission to win the title for his wife Susann, who died in a car accident in July last year. The German team said he used the personal tragedy to motivate himself to win the gold medal.
Chigishev was the strongest in the snatch session Tuesday. He kissed his fists after a 210-kg lift that gave him a 7-kg advantage over fourth-placed Steiner going into the second event -- the clean and jerk. He let out a victorious roar after clearing 250 kg in his last lift, but the glory was short-lived as Steiner stunned（使瞠目）everyone with his final, winning clean and jerk effort.
Steiner had finished seventh in the 2004 Olympics in the 105kg weight category, and took the gold in the 2008 European Championship +105kg snatch competition, bronze in the clean and jerk and silver overall, with a total weight of 446kg.

The Growing Credit Crisis Forces Many Companies to Seek Government Help
On September fifteenth, Lehman Brothers, a one hundred fifty-eight year-old investment bank, sought legal protection from its creditors. It had failed to find a buyer after months of searching. With over six hundred billion dollars in debt, Lehman’s failure was the largest bankruptcv in United States history At the same time，the nation’s biggest insurance company，American International Group, had gotten into trouble selling credit default swaps These are contracts Similar to insurance that protect the holder against credit risk.
Credit rating agencies downgraded A.I.G because of concerns it could not honor its contracts. Unable to get new loans, A.I.G asked for government help The Federal Reserve agreed to loan A .I.G. eighty-five billion dollars in return for eighty percent of the company but it was not enough. By November, the government had extended a total of about one hundred fiftv billion doliars in aid to A .I.G—the most to any single company during the crisis.
As banks refused to lend, Treasury Secretary Henry Paulson proposed a plan to loosen credit markets by buylng risky assets. Congress approved the Emergency Economic Stabilization Act of Two. Thousand eight on October third The bill provided seven hundred billion dollars to buy hard to-value securltles from banks. But within weeks, the government changed plans. The Treasury moved to invest two handred fifty billion dollars directly in banks to help them lend money again.
Lack of credit not only hurt banks but manufacturers, too. Falling car sales threatened America’s carmakers The big three automakers—General Motors, Ford and Chrysler—told Congress that they needed loans or they faced bankmptcy. In December, President Bush offered G.M and Chrysler over seventeen billion dollars in loans.
As the year ended, the Federal Reserve tried to support economic growth by lowering its main interest rate to nearly zero for the first time. But there was one more bad surprise New York money manager Bernard Madoff admitted he had cheated investors out of fifty billion dollars.

A simple piece of clothesline hangs between some environmentally friendly Americans and their neighbors.
On one side stand those who see clothes dryers(干衣机) as a waste of energy and a major polluter of the environment. As a result, they are turning to clotheslines as part of the “what-I –can do environmentalism(环境保护主义).”
On the other side are people who are against drying clothes outside, arguing that clotheslines are unpleasant to look at. They have persuaded Homeowners Associations (HOAs) access the U.S. to ban outdoor clotheslines, because clothesline drying also tends to lower home value in the neighborhood. This had led to a Right-to-Dry Movement that is calling for laws to be passed to protect people’s right to use clotheslines.
So far, only three states have laws to protect clothesline. Right-to-Dry supporters argue that there should be move.
Matt Reck, 37, is the kind of eco-conscious(有生态意识的) person who feeds his trees with bathwater and reuses water drops from his air conditioners to water plants. His family also uses a clothesline. But on July 9, 2007, the HOA in Wake Forest, North Carolina, told him that a dissatisfied neighlzir had telephoned them about him clothesline. The Recks paid no attention to the warming and still dried their clothes on a line in the yard. “Many people say they are environmentally friendly but they don’t take matters in their own hands,” says Reck. The local HOA has decided not to take any action, unless more neighbors come to them.
North Carolina lawmakers are saying that banning clotheslines is not the right thing to do. But HOAs and housing businesses believe that clothesline drying reminds people of poor neighborhoods. They worry that if buyers think their future neighbors can’t even afford dryers, housing prices will fall.
Environmentalists say such worries are not necessary, and in view of global warming, that idea needs to change. As they say, “The clothesline is beautiful”. Hanging clothes outside should be encouraged. We all have to do at least something to slow down the process of global warming.”One of the reasons why supporters of clothes dryers are trying to ban clothesline drying is that ____.
| A．clothes dryers are more efficient | B．clothesline drying reduces home value |
| C．clothes dryers are energy-saving | D．clothesline drying is not allowed in most U.S. states |
Which of the following best describes Matt Reck?
| A．He is a kind-hearted man. | B．He is an impolite man. |
| C．He is and experienced gardener. | D．He is a man of social responsibility. |
Who are in favor of clothesline drying?
| A．housing businesses. | B．Environmentalists. |
| C．Homeowners Associations. | D．Reck’s dissatisfied neighbors. |
What is mainly discussed in the text?
| A．Clothesline drying: a way to save energy and money. |
| B．Clothesline drying: a lost art rediscovered. |
| C．Opposite opinions on clothesline drying. |
| D．Different varieties of clotheslines. |
For a while, my neighborhood was taken ever by an army of joggers(慢跑者). They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. "Come on!" My friend Alex encouraged me to join him as he jogged by my house every evening. "You'll feel great."
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I'm not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet a real pounding（追击）ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn't kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn't my idea of fun. Jogging is also a lonely pastime. Some joggers say, "I love being out there with just my thoughts" Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn't just the first week: it was practically every day for two months. I never got past the pain level, and pain isn't fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don't jog any more, and I don't think I ever will. I'm walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise, and I'm enjoying it at the same time. I could never say the same for jogging, and I've found a lot of better ways to stay in shape.
