Antarctica is the only continent where there has never been war. No military activity is allowed there and scientific research is a priority. Defined as all of the land and ice shelves south of latitude 60 degrees south, the 5.5m square miles (14.2m square km) of the world’s coldest, driest, windiest and most remote land mass are protected by the Antarctic Treaty, which came into force in June 1961 and designated the land "a natural reserve, devoted to peace and science".
It was not always so, writes David Day, an author, historian and research associate at La Trobe University in Melbourne. Solid as a block of Antarctic ice itself, but no less readable for it, his latest book draws on five years of meticulous research to tell the story of human endeavor in Antarctica, the last continent to be discovered. It paints a poignant biographical picture of the characters involved, the gruelling expeditions undertaken, and the rivalries between nations as they raced to chart the continent and claim possession of it.
Mr. Day begins with Captain James Cook who, aboard the Resolution in 1773, became the first man to cross the Antarctic Circle. Although the ice-covered sea stopped him from getting close enough to see the Antarctic land mass, boulders in icebergs proved its existence. Yet Cook did not think the area was worth exploring. "I will be bold to say that the world will not be benefited by it," he stated.
Antarctica’s future as a natural reserve is by no means assured. Whereas the treaty designed to protect it has certainly preserved peace and served as an example of co-operation between nations, the prospect of mineral and oil deposits under Antarctica’s ice cap is attracting the attention of resource-starved countries and big business alike. In addition, environmental groups, scientists and tourists are all making their own demands. As Mr. Day writes, " For centuries, the Antarctic defied man’s approach, now its dangers and its terrors have been largely conquered. Only its future remains unknown."
What does the sentence "Antarctica’s future as a natural reserve is by no means assured" (Para. 4) mean?
选项
A、It can not be guaranteed that Antarctica will be a natural reserve.
B、It is sure that Antarctica will be a natural reserve.
C、It is very possible that Antarctica’s future is filled with uncertainty.
D、Antarctica’s future as a natural reserve is assured.
答案
A
解析
句子Antarctica’s future as a natural reserve is by no means assured意为“未来的南极洲作为一个自然保护区是绝对没有得到保证的”。所以可以很明确地选出A选项。
