The Chinese Antarctica expedition returned to Shanghai on March 20 following a month living on the ice. It was the first time Chinese scientists had visited the Amery Ice Shelf—the longest ice shelf in the world. The team collected ice samples and data on temperatures, which are necessary for research on global warming. So far, about 27 countries have visited Antarctica for scientific research. Although the living conditions are very hard, many scientists have to stay there for long periods of time. So, how do they manage their lives on the ice?
    During the summer, the temperature in Antarctica reaches about -20℃. It falls to about -60℃ in winter. So, even if there are 24 hours of sunshine, scientists must keep wearing all the correct clothes to protect them from the cold. These clothes include jeans, running shoes, jackets, long underwear, boots and woolen socks. Although highly technical clothing provides much protection against the extreme cold, scientists often need to go outside when there is an icy wind blowing and the temperature is -30℃. Natural protection such as facial hair can also help. "That’s why many researchers wear a beard. It really does keep you warm," says German explorer Arved Fuchs. Usually, the polar researchers have good meals. Some even have feasts on holidays like Christmas and New Year’s Day. Vegetables are always welcomed and usually finished the quickest. Life on the ice means living with other researchers in tight living spaces. Most people sleep in dorm-style rooms. More remote field camps use separate tents. So, at least some researchers don’t have to put up with annoying snorers.
13. Why did researchers visit Amery Ice Shelf?
14. What is the matter that researchers care most for living in Antarctica?
15. What best describes the living space of most researchers on the Amery Ice Shelf?

选项 A、Because Amery Ice Shelf is the largest and most typical ice shelf.
B、Because they wanted to challenge themselves in extreme climate.
C、Because they desired to collect stuff to study global warming.
D、Because they were curious of the living conditions there.

答案 C

解析 原文提到,人们到Amery Ice Shelf为研究全球变暖搜集冰块样本和数据,故C为答案。在这类说明文中,考察的目的是很重要的信息点.通常在文章的开头部分就有所交待。文章的开头部分介绍了考察队的基本情况,包括此行目的,C是对这个描述的同义概括。
