It is hard not to get the message.The virtues of physical fitness are shown on magazine covers,postage stamps,and television ads for everything from beauty soaps to travel books.Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercises.Growing publicity for races held in American cities helped fuel a strong interest in the ancient sport of running. Although Americans have also discovered other forms of exercise(such as walking and swimming,running__________________________.

      As the popularity of exercise continues to increase, so does scientific evidence of its health benefits. The key to fitness is exercising the major muscle group vigorously enough to approximately double the heart rate and keep it doubled for 20 to 30 minutes at a time.Doing such physical exercises three times or more a week will produce considerable improvements in physical health in about three months.

  American government has suggested a new plan to increase the study of foreign languages in schools.

  Research has shown that childhood is a better time than manhood to learn foreign languages.However, ________ learn only English.Less than one third of American elementary schools teach foreign languages.Only 44 percent of American high school students take a foreign language.And 70 percent of them are learning Spanish.What’s more, the United States doesn’t have enough foreign teachers.

  The plan calls for teaching more children foreign languages, as early as the age of four.Most of the new teaching would be in languages not widely taught now in American schools.These include Arabic, Chinese, Farsi(波斯语), Hindi(北印度语)and Russian.It also aims to increase foreign language instruction in colleges and graduate schools.The hope is to bring more foreign language speakers into government service.

  Administration officials will ask for 114 million dollars in 2007 to start the program.The money would be used to help foreign-language students pay for their educations.The plan also calls for sending more American students to other countries to study.And it calls for bringing more foreign language teaching assistants to the United States.

  In a word, to face the uncertain challenges in the future, America needs more officers, teachers, and students who can understand foreign languages.It will also improve the understanding and cultural exchange between America and other countries around the world

  Beneath the ocean’s surface, an active world surrounds the globe.A lot of spotted fish swim through coral reefs.

  But time is running out for these underwater treasures.Last month, at the National Oceanic and Atmospheric Ad-ministration's coral-reef meeting, researchers warned that 60% of the world's coral could die within the next 25 years.About 27% of the living underwater cities have already been lost.

  Though some coral formations are similar to lifeless stone, coral is made up of tiny animals called coral polyps.They grow and divide to build coral colonies.their bones are left behind.New corals grow on top, forming reefs.The complex reef ecosystem covers less than 1% of the ocean floor, yet supports about 25% of all marine life.An ecosystem is a partnership between living things and their environment.

  The destruction of coral reefs puts many species at risk of extinction.Some researchers say that at least 1 million species of plants and animals live in the world's reefs.On October 29, scientists said they had discovered new reef species in the waters off Hawaii.

  Water that is warmer than normal can cause deadly coral bleaching(漂白).Coral contains tiny algae(藻类).They give coral its beautiful color.Coral uses the algae to create food and grow.At high temperatures, corals get stressed and release the algae.Without the algae, coral loses its color and starves.The weakened coral becomes more sensitive to sun-light and disease.Last year, warming in the Caribbean Sea bleached more than 90% of the coral on many reefs.

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.)

4.What do you think of expedition?

  All plant cells(细胞)are capable of taking up water.Even dead ones do to a certain degree.Absorption(吸收)of water by dead cell walls makes wood become larger.In common land plants, the living cells of roots take up most of the water.Land plants without roots do exist, however.Those greenish yellow lichens(苔藓)you see on rocks in the high mountains have no roots.Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots.

  ________.These flowering plants are “the higher plants” because they evolved(进化)recently and are thus considered higher on the evolutionary scale(进化度).In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad.It is a relative of the pineapple.Even if this plant had roots, they would be of no use, because where the plant grows, it never rains.The plant gets its water only from the dew(露水)it collects at night, when its leaves cool off.Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open.If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies.In the southern United States and in Puerto Rico, one sees bromeliads growing high above the streets on the insulation(绝缘物)of electric wires.These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.

1.What’s the most suitable title?(Please answer within 10 words.)

________________________

2.How does the “bromeliad” get the water?(Please answer within 10 words.)

4.Which sentence can be replaced by the following one?

The plant grows in a place where there isn’t any rain.

5.Translate the underlined sentence in the third paragraph into Chinese.
