　　The ability of forests to absorb man-made CO2 is weakening, according to an analysis of two decades of data from more than 30 sites in the frozen north．

　　The study was conducted by a team of Canadian, Chinese and European researchers and published in the science journal Nature on January 3．The findings mean that more of the CO2 we release will end up affecting the climate rather than being safely locked away in trees or soil．

　　As plants take up more CO2, that should put a break on CO2 increases, scientists once thought．However, the new data suggest that this idea is too simplified．The research team monitored the date in autumn at which the forests switched from being a net sink for carbon into a net source．Instead of moving later in the year as they had expected, this date actually got earlier－in some places by a few days, but in others by a few weeks．

　　“This means potentially a bigger warming effect,”said Timo Vesalai, who led the study．The precise effect the trend will have on future warming is hard to predict．But the research could partly explain why the amount of CO2 in the atmosphere is increasing faster than expected．

　　Currently, half of the man-made CO2 is absorbed by oceans and ecosystems on land．

　　Between 1970 and 2000, the CO2 concentration(濃度)in the atmosphere rose by 1.5ppm．Since 2000 the annual rise leap to an average of 1.9ppm－35％ higher than expected．

　　In China, the average temperature in 2007 was 1.3℃ higher than the average temperature between 1970 and 2000．

　　So, it is time for us to take action now．

At the bottom of the world lies a mighty continent still wrapped in the Ice Age and, until recent times, unknown to man. It is a great landmass with mountain ranges whose extent and elevation are still uncertain. Much of the continent is a complete blank on our maps. Man has explored, on foot, less than one percent of its area.

Antarctica differs fundamentally from the Arctic regions. The Arctic is an ocean, covered with drifting packed ice and hemmed in by the landmasses of Europe, Asia, and North America. The Antarctica is a continent almost as large as Europe and Australia combined, centered roughly on the South Pole and surrounded by the most unobstructed water areas of the world—the Atlantic, Pacific, and Indian Oceans.

The continental ice sheet is more than two miles high in its center; thus, the air over the Antarctica is far more iced than it is over the Arctic regions. This cold air current from the land is so forceful that it makes the nearby seas the stormiest in the world and makes unlivable those regions whose counterparts (配對物) at the opposite end of the globe are livable. Thus, more than a million persons live within 2, 000 miles of the North Pole in an area that includes most of Alaska, Siberia, and Scandinavia—a region rich in forest and mining industries. Apart from a handful of weather stations, within the same distance of the South Pole there is not a single tree, industry or settlement.

66. The best title for this passage would be________ .

A. Iceland

B. Land of Opportunity

C. Utopia at Last

D. The Unknown Continent

67. At the time this article was written, our knowledge about Antarctica was______.

A. very limited                                                 B. vast

C. fairly rich                                                    D. non-existent

68. What’s the fundamental difference between Antarctica and the Arctic?

A. The Arctic is an ocean while Antarctica is a continent.

B. The Arctic is inhabited by people while Antarctica is uninhabitable.

C. The Arctic is covered with ice while Antarctica is surrounded by water.

D. The Arctic is surrounded by continents while Antarctica is bordered by oceans.

69. The Antarctica is made uninhabitable primarily by________.

A. ice                                                                     B. calm seas

C. cold air                                                              D. lack of water

70. According to this article,________ .

A. 2, 000 people live on the Antarctica Continent

B. a million people live within 2, 000 miles of the South Pole

C. weather conditions make settlements impractical

D. only a handful of natives inhabit Antarctica
