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

 

阅读下面短文并回答问题，然后将答案写到相应的位置上（请注意问题后的字数要求）

〔1〕There are many useful suggestions and pieces of advice that can help one to improve English. Here are some useful suggestions and new tips to increase one’s English language vocabulary.

〔2〕Learning English vocabulary is about much more than just learning the right words. A broad grasp of vocabulary in the English language is based on understanding important expressions and “word combinations”, which means groups of words that often or always go together.

〔3〕Learning a word will not help very much if you quickly forget it. Research shows that it takes from 10 to 20 repetitions to really make a word part of your vocabulary. Since most words are learned from how they are used in context （上下文）, the more words one is exposed to（接触）, ________. Keep a writing pad close to you. When you read, pay close attention to the word you do not know, write the word down and try to guess its meaning from the context. Then look up the word in a dictionary.

〔4〕Remember that if you do not use English words that you have just learned in conversation or writing, you will forget them very quickly. So the best way to learn new words effectively is just by trying to use them in conversation and writing. Remember also that practice is the key to fluent spoken English.

〔5〕Building vocabulary is a life-long task. Remember, “In the beginning was the word.” Your future could depend on how rich your vocabulary is. It will also determine the quality of your communication.

People have wondered for a long time how their personalities and behaviors are formed．It is not easy to explain why one person is intelligent and another is not, or why one is cooperative （合作的）and another is competitive．

Social scientists are, of course, extremely interested in these types of questions．They want to explain why we possess certain characteristics and exhibit certain behaviors．There are no clear answers yet, but two distinct schools of thought （学派）on the matter have developed．As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory．The controversy（argument) is often referred to as “nature and nurture（教育）”．

Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors．That our environment has little, if anything, to do with our abilities, characteristics, and behavior is central to this theory．Taken to an extreme(走极端）, this theory maintains that our behavior is predetermined to such a degree that we are almost completely governed by our instincts（本能）．

Proponents of the “nurture” theory, or, as they are often called, behaviorists, claimed that our environment is more important than our biologically based instincts in determining how we will act．A behaviorist, B．F．Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings．The behaviorists’ view of the human being is quite mechanistic（机械论的）; they maintain that, like machines, humans’ respond to environmental stimuli（刺激） as the basis of their behavior．

Socially and politically, the consequences of these two theories are far-reaching．In the US, for example, blacks often score below whites on standardized intelligence tests．This leads some proponents to conclude that blacks are genetically lower in status than whites．Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do．

Either of these theories cannot yet fully explain human behavior．In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes. That the controversy will continue for a long time is certain．

A．relation between personality and behavior

B．differences between the blacks and whites

C．racial discrimination in the United States

D．different responds to intelligence tests

A．To call our attention to the changes of human behavior．

B．To urge scientists to do more research in social science．

C．To give us a detailed explanation of human behavior．

D．To present an argument in the field of social science．
