Shanghai is the largest city in China with well-developed business and industry, and also holds a leading place in China's arts, sciences and education. About eleven million people make their homes in Shanghai. This enormous city spreads out along the banks of the Huang Pu River, which flows into the mouth of the Yangtze River about fourteen miles north.
Shanghai began as a fishing village in the 11th century, but by the mid-18th century it was an important area for growing cotton. After 1842 when China lost the Opium War with Great Britain, the British realized that Shanghai was in an excellent location to serve as a seaport for the densely populated Yangtze River Plain. They forced the Chinese government to allow English traders to settle on the wastelands outside the
city walls. Later, French, American, and Japanese traders also came to Shanghai and were allowed to live in certain territorial zones without being under the Chinese laws. The foreigners built whole new sections of Shanghai, including homes, stores, factories, and office buildings. Thousands of Chinese poured into Shanghai in search of jobs, most of whom settled in the old part of the city. As a result of all the foreigners, Shanghai became greatly influenced by Western culture.
During the 1900s, opium sales along with the gambling brought in big profits. After the Anti-Japanese War in 1945, the Nationalist Chinese government took over the city. In 1949, Shanghai was liberated and administrated under the Communist Chinese government. Since the 1990s, Shanghai has developed quickly and has become a new international metropolis in China and will host the World Expo in 2010.

Beijing opera or Peking opera (Pinyin: Jīngjù) is a form of Chinese opera which arose in the late 18th century and became fully developed and recognized by the mid-19th century.The form was extremely popular in the Qing Dynasty court and has come to be regarded as one of the cultural treasures of China.Major performance troupes (剧团,戏班子) are based in Beijing and Tianjin in the north,and Shanghai in the south.The art form is also enjoyed in Taiwan,and has spread to other countries such as the United States and Japan.
Beijing opera features four main types of performers.Performing troupes often have several of each variety,as well as numerous secondary and tertiary performers.With their elaborate (认真的,精心的) and colorful costumes,performers are the only focal points on Beijing opera's characteristically small stage.They make use of the skills of speech,song,dance,and combat in movements that are symbolic and suggestive,rather than realistic.Above all else,the skill of performers is evaluated according to the beauty of their movements.Performers also hold a variety of stylistic conventions that help audiences navigate the plot of the production.The layers of meaning within each movement must be expressed in time with music.The music of Beijing opera can be divided into the Xipi and Erhuang styles.Melodies include arias (唱腔),fixed-tune melodies,and percussion patterns.The repertoire of Beijing opera includes over 1,400 works,which are based on Chinese history,folklore,and,increasingly,contemporary life.
In recent years,Beijing opera has attempted numerous reforms in response to sagging audience numbers.These reforms,which include improving performance quality,adapting new performance elements,and performing new and original plays,have met with mixed success.Some Western works have been adopted as new plays,but a lack of funding and an adverse political climate have left Beijing opera's fate uncertain as the form enters the 21st century.

By the mid-nineteenth century, the “icebox” had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns, and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families of their own use. This had become possible because a new household convenience, the icebox, a precursors of modern refrigerator, had been invented.
Making an efficient icebox was not as easy as we might now suppose. In the early nineteenth century, the knowledge of physics of heat, which was essential to a science of refrigeration, was rudimentary. The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox.
But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium(奖金) price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.
【小题1】What does the passage mainly discuss?

A.The influence of ice on the diet.
B.The development of refrigeration.
C.The transportation of goods to market.
D.Sources of ice in the nineteenth century.
【小题2】According to the passage, when did the word “icebox” become part of the language of the United States?
A.in 1803B.sometime bore 1850
C.during the civil warD.near the end of the nineteenth century.
【小题3】The phrase “forward-looking” in line 3 is closest in meaning to______.
A.progressiveB.popularC.thriftyD.well-established
【小题4】The author mentions “fish” in the passage because _____.
A.many fish dealers also sold ice.
B.fish was shipped in refrigerated freight cars.
C.fish dealers were among the early commercial users of ice
D.fish was not part of the ordinary person’s diet before the invention of the icebox.

WASHINGTON—Two-thirds of the world’s polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday.

The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species.

“There is a definite link between changes in the sea ice and the welfare of polar bears,” said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat(退却) farther this month.

That means that polar bears—some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing(简报).

Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century’s end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland.

“It is likely to result in loss of approximately two-thirds of the world’s current polar bear population by the mid 21st century,” the report’s executive summary said.

“Because the observed trajectory(轨迹)of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative(保守的).”

In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food.

Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears’ disappearance would probably take place as young cubs(幼兽)failed to survive to adulthood and females were unable to reproduce successfully.

1.What was the US Geological Survey intended to do?

A.To determine whether the polar bear was in danger.

B.To measure how fast the sea ice melts in the Arctic.

C.To check the predictions of the computer models.

D.To find out the exact number of the polar bear.

2.What causes the polar bears to disappear by 2050?

A.The pollution of the Arctic region.           B.The sea ice melting at high speed

C.Fewer food sources being left.             D.The temperature getting colder.

3.The key to preventing polar bears dying out seems to _______________.

A.help young polar bears to survive the cold winter

B.have large number of seals living in the oceans

C.make sure there is enough sea ice in the Arctic

D.provide chances for adult polar bears to reproduce
