The Cold Places

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 Fahrenheit below zero. Readings of 85 degrees below zero are common in both the Arctic and Antarctica. Winter temperatures average 30 degrees below zero in the Arctic. At the South Pole the winter is about 73 degrees below zero.

One thing alone makes it almost impossible for men to live in Antarctica and in parts of the Arctic.This one thing is the low temperature --- the killing chill of the 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 moment can they be unprotected against the below-zero temperature.

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 the 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 may have been much like our own.

Explores 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.

1. As discovered by expedition scientists, Antarctica has not always been so cold as it is today, so has the Arctic.

A. Right B. Wrong C. Not mentioned

6. The lowest temperature that man has ever known was recorded in Antarctica.

A. Right B. Wrong C. Not mentioned

7. At one time, the weather in Antarctica was so warm and damp that trees grew there.

A. Right B. Wrong C. Not mentioned
答案及解析:

1. C。文章的倒數第2段的第2句中提到了expedition scientists,并說南極洲那里的氣候曾經一度象我們現(xiàn)在生活的'地區(qū)的氣候那樣溫和,但并沒說道北極也是如此。

2. B。線索詞及關鍵詞average(平均)。第2段的最后1句中包含average一詞,該句說“南極洲冬天的平均溫度是零下73度。”,所以該問題句的說法錯誤。

3. B。該問題說“因為南極和北極的嚴寒,這些地區(qū)是無人區(qū)。”憑直覺判斷這種說法太絕對,應該是錯誤的。注意:說的絕對的句子一定不正確。在原文中的第3段的段首句說“僅一個原因就使得南極洲和部分的北極地區(qū)幾乎不可能讓人居住。”,依據此也可判斷該問題句不正確。

4. B。原文第4段的段首句中出現(xiàn)了survive(生存)一詞,該句及其緊接的一句說“為了生存,人們必須修建防風屏障。”,憑借此判斷該問題句的說法也不正確。

5. A. 原文中的第6段中對極地動植物進行了論述,且其表述的含義與問題句一致。

6. A。文章第2段的段首句中提到了Antarctica,接著的一句說“南極洲保持著世界的低溫記錄。”,所以該問題句的說法正確。

7. A。文章的最后1段的段首句說“探險者在南極發(fā)現(xiàn)了煤。”, 而緊接的一句講述的正是該問題句所講述的內容。
