The
Arctic is a polar region. It surrounds the North Pole. Like
Antarctica, the Arctic is a land of ice and snow. Antarctica holds the record
for a low temperature reading--125 degrees Fahrenheit below zero. Reading of 85
degrees below zero is common in both the Arctic and Antarctica. Winter
temperatures average 30 degrees below zero in the Arctic. At the South Pole the
winter average is about 73 degrees below zero. One thing alone
makes it almost impossible for men to live in Antarctica and in parts of the Arc
tic. This one thing is the low temperature--the killing chill of far North and
the polar South. To survive, men must wear the warmest possible
clothing. They must build windproof shelters.They must keep heaters going at all
times. Not even for a moment can they be unprotected against the below-zero
temperatures. Men have a way of providing for themselves. Polar
explorers wrap themselves in warm coats and furs. The cold makes life difficult.
But the explorers can stay alive. What about animals? Can they
survive? Do we find plants? Do we find life in the Arctic and in Antarctica?
Yes, we do. There is life in the oceans. There is life on land.
Antarctica, as we have seen, is a cold place indeed. But this has not
always been the case. Expedition scientists have discovered that Antarctica has
not always been a frozen continent. At one time the weather in Antarctica may
have much like our own. Explorers have discovered coal in
Antarctica. This leads them to believe that Antarctica at one time was a land of
swamps and forests. Heat and moisture must have kept the trees in the forests
alive.
单选题
The lowest temperature that man has ever known was recorded in Antarctica.
【正确答案】
A
【答案解析】[解析] 本题给出的信息是正确的。答案相关句在第二段：“Antarctica holds there cord for a low temperature reading--125 degrees Fahrenheit below zero.”。
单选题
Winter temperatures average 85 degrees below zero in Antarctica.
【正确答案】
B
【答案解析】[解析] 本题给出的信息是错误的。第二段最后一句“At the South Pole the winter average is about 73 degrees below zero.”,与该题目“Winter temperatures average 85 degrees below zero in Antarctica.”不一致。
单选题
The Arctic and Antarctica are no man's lands because of their notorious coldness.
【正确答案】
B
【答案解析】[解析] 本题给出的信息是错误的。原文描述了科学家怎样通过保护自己在南极能够生存。
单选题
Polar explorers can stay alive without heaters and windproof shelters.
【正确答案】
B
【答案解析】[解析] 本题给出的信息是错误的。第四段提到“They must build windproof shelters.They must keep heaters going at all times.Not even for a moment call they be unprotected against the below-zero temperatures.”第五段也说“Polar explorers wrap themselves in warm coats and furs.”。
单选题
Despite the hostile environment, both animals and plants can be found in the oceans and on land in polar areas.
【正确答案】
A
【答案解析】[解析] 本题给出的信息是正确的。倒数第三段说“Do we find life in the Arctic and in Antarctica?Yes,we do.There is life in the oceans.There is life on land.”。
单选题
As discovered by expedition scientists, Antarctica has not always been so cold as it is today, so has the Arctic.
【正确答案】
C
【答案解析】[解析] 本题给出的信息未提及。前半句“As discovered by expedition scientists，Antarctica has not always been so cold as it is today”在文章的最后两段提到了，但“so has the Arctic”并未提到。
单选题
At one time, the weather in Antarctica was so warm and damp that trees grew there.
【正确答案】
A
【答案解析】[解析] 本题给出的信息是正确的。最后一段说“Explorers have discovered coal in Antarctica.This leads them to believe that Antarctica at one time was a land of swamps and forests.Heat and moisture must have kept the trees in the forests alive.”。
