5.In 1990,biologists counted 201,039walruses in the Arctic Ocean.Now,over 20years later,it seems there are fewer.After three years of counting,the US Fish and Wildlife Service estimates that there are only 15,164walruses in the area.But,scientists say,"They've not finished counting."
"We're still working on the final population estimate,"said Suzann.She is a wildlife biologist with the US Fish and Wildlife Service.
Endangered Species?
What's a possible reason for the lower walrus count?Brendan Cummings,a spokesperson for
the Center for Biological Diversity (多样性),thinks many walruses are dying.He believes global warming is melting the ice in the waters between Alaska and Russia.That's the area where most walruses live.However,they can't live without ice.
But other scientists aren't so sure that the walruses are dying out.The US Fish and Wildlife Service biologist Doug Bum said,"We realized we were missing a lot of walrus groups."So the walrus count goes on.The counting hasn't been easy.Scientists sometimes have to guess the number of walruses that are underwater.
US law requires scientists to count the walruses every three years.Then,if the mammals (哺乳动物) turn out to be an endangered species,they will be counted every year.

分析 文章大意:
文章主要讲述的是关于海象的情况.现在,美国协会每三年统计一次海象的数量,计数的原因是为了统计海象到底还有多少,确定其是否成为了一种濒危动物.因为随着全球变暖,极地的冰川加速融化,海象的生存环境正在减少,数量也在迅速下降.
解答 66.C,推理判断题,文中提到"The aim:to decide whether the walrus is an endangered species"计数的原因是为了统计海象的数量,确定其是否成为了一种濒危动物,由此确定选择C.
67.B,词义猜测题,前文提到"the US Fish and Wildlife Service estimates that there are only 15,164walruses in the area.But,scientists say,"They've not finished counting"美国统计协会说目前海里还有15164个海象,但此数据发表时统计还在继续,由此判断此数字为一个大概的数字,是一个估算值,所以estimate为估算,表明并非准确的数字,所以选择B.
68.B,推理判断题,文中提到"if the mammals (哺乳动物) turn out to be an endangered species,they will be counted every year"如果一种哺乳动物确定为濒危动物,那么他们的数量将会每年统计一次,由此确定选择B.
69.D,推理判断题,文中提到"He believes global warming is melting the ice in the waters between Alaska and Russia.That's the area where most walruses live.However,they can't live without ice."Brendan Cummings 认为海象正面临着死亡,因为他们生活离不开冰,但是极地的冰因为全球变暖在加速融化,由此确定选择D.
70.D,推理判断题,文中提到"US law requires scientists to count the walruses every three years"美国协会现在没三年统计一次海象的数量,而濒危动物数量则是每年统计一次,虽然现在还有很多,但是随着全球变暖,海象的生存情况不容乐观,由此确定选择D.
点评 对于阅读表达题,一定要记得首先通读全文,了解文章大意,然后再根据文章关键词,关键句,掌握细节问题,并进行推理判断,再去回答具体的问题.
