　　Where did you see a polar bear? At a zoo, perhaps If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These “Polar Bears” are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3℃, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island , New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.

　　Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart best stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.

　　The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favourite form of exercise is very good for the circulatory system （循环系统） because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.

　　The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, “When I go into the water, I pour my troubles into the ocean and let them float away.”

短文理解

　　The Chinese Antarctica expedition returned to Shanghai on March 20 following a month living on the ice．It was the first time Chinese scientists had visited the Amery Ice Shelf－the longest ice shelf in the world．

　　The team collected ice samples and data on temperatures, which are necessary for research on global warming．

　　So far, about 27 countries have visited Antarctica for scientific research．Although the living conditions are very hard, many scientists have to stay there for long periods of time．

　　So, how do they manage their lives on the ice?

　　Well, during the summer, the temperature in Antarctica reaches about －20 ℃．It falls to about －60℃ in winter．So, even if there are 24 hours of sunshine, scientists must keep wearing all the correct clothes _________．These clothes include jeans, running shoes, jackets, long underwear, boots and woolen socks．

　　Although highly technical clothing provides much protection against the extreme cold, scientists often need to go outside when there is an icy wind blowing and the temperature is －30℃．Natural protection such as facial hair can also help．

　　“That’s why many researchers wear a beard．It really does keep you warm．”says German explorer Raved Fuchs．

　　Usually, the polar researchers have good meals．Some even have feasts on holidays like Christmas and New Year’s Day．Vegetables are always welcomed and usually finished the quickest．

　　Life on the ice means living with other researchers in tight living spaces．Most people sleep in dormitory style rooms．More remote field camps use separate tents．So, at least some researchers don’t have to put up with annoying snores(鼾声)。

　　But what do they do for fun in their spare time? There are actually a lot of things they can do．They watch movies, read tons of books, listen to music, visit saunas, paint and ski．Some female researchers might even do some knitting．

　　It is important for a polar researcher to be in good physical condition．They can be required to climb to heights of more than 3, 000 meters．And the Antarctic atmosphere has less oxygen than that of any other continent．

1．Why is the expedition designed?(Please answer within 10 words．)

2．Which sentence in this passage can be replaced by the following one?

Hard as the living condition, one must…

___________________

3．Please fill in the blank in the passage with proper words or phrases to complete the sentence．(Please answer within 10 words．)

A Plan For Exploring Mars

NASA is moving ahead with plans to put a long－armed lander on Mars' icy north pole to search for clues (线索) for water and possible signs of life.

The MYM386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008.The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples (标本，样品) to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice－rich soil near the arctic surface.

Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbes(微生物)existed in the ice.

Phoenix will be the first mission of the Mars Scout program, a renewed, low－cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth，” Peter Smith said.

True to its name, Phoenix rose from the ashes of previous(先前的) missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well－known disappearance of the Mars Polar Lander in 1999.The Polar Lander lost contact during a landing attempt near the planet's south pole after its rocket engine shut off prematurely,_causing the spacecraft to fall about 130 feet to almost certain destruction.

The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench－digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later.

1．The passage mainly tells readers that ________.

 A．clues of water will be found in Phoenix

 B．Phoenix will be sent to find clues of water on Mars

 C．August 2007 will see Phoenix lift off

 D．the Mars Scout program will be carried out

2．The underlined word “prematurely” (Paragraph 5) means “________”．

A．on time            B．behind the time

C．out of work          D．ahead of time

3．According to the passage, we know Phoenix will land on Mars ________.

A．in May 2008        B．in August 2007   

C．in August 2008      D．in September 2008

4．According to the passage, the name “Phoenix” is after the meaning of ________.

 A．rebirth  B．death  C．energy  D．hope

5．After Phoenix lands on Mars, we can infer it will firstly ________.

A．find soil samples and send them to the earth

B．look for the icy land to dig for the soil samples

C．take photos and send them to the earth

D．find the remains of the Mars Polar Lander

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect" - holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.

Another view, less widely held, is that increasing particulate (废气排往空中而形成的微粒、颗粒) matter in the atmosphere is blocking sunlight and lowering the earth's temperature ─ a result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.

1. As pointed out at the beginning of the passage, people used to think that air pollution ______.

   A. caused widespread damage in the countryside

   B. affected the entire eastern half of the United States

   C. had damaging effects on health

   D. existed merely in urban and industrial areas

2. As far as the greenhouse effect is concerned, the author ______.

   A. shares the same view with the scientists

   B. is uncertain of its occurrence

   C. rejects it as being ungrounded

   D. thinks that it will destroy the world soon

3. The underlined word “offset" in Para. 2 could best be replaced by______.

   A. slip into         B. make up for      C. set up          D. catch up with

4. This passage is mainly concerned with ______.

   A. the greenhouse effect                 B. the burning of fossil fuels

   C. the potential effect of air pollution                   D. the possibility of a new ice age
