By the end of this century, the average world temperature is expected to increase between one and four degrees, with widespread effects on rainfall, sea levels and animal habitats. But in the Arctic, where the effects of climate change are most intense, the rise in temperature could be twice as much.
Understanding how Arctic warming will affect the people, animals, plants and marine life and economic activity in Canada\’s North is important to the country\’s future, says Kent Moore, and atmospheric physicist at University of Toronto Mississauga who is participating in a long-term, international study of the marine ecosystem along the Beaufort Sea, from Alaska to the Mackenzie delta.
The study will add to our knowledge of everything from the extent of sea ice in the region to how fish stocks will change, to which areas could become targets for oil and gas exploration, to the impact on the indigenous people who call this part of the country home.
Moore, who has worked in the Arctic for more than 20 years, says his research has already found that thinning sea ice and changes in wind patterns are causing an important change in the marine food chain: phytoplankton (浮游植物) is blooming two to three weeks earlier. Many animals time their annual migration to the Arctic for when food is plentiful, and have not adapted to the earlier bloom. \\
1.By the end of this century, according to the author, global warming will________.(D)
A. start to bring about extreme weather events to humans and animals
B. increase the average world temperature by four degrees
C. cause more damages to the whole world than expected
D. affect the Arctic more than any other parts of the earth
解析：细节题。从第一段的最后一句“But in the Arctic, where the effects of climate change are most intense, the rise in temperature could be twice as much．”可知，全球变暖对北极的影响是most intense (最集中的)，温度上升是其他地区的两倍。因此本题正确答案为D。
2.To help understand the destructive mechanism of Arctic warming, as indicated by the passage, the international study________.(D)
A. is conducted with every single discipline of University of Toronto
B. pioneers in pursuing the widespread effects of climate change
C. involves so many countries for different investigations
D. is intended to deal with various aspects in research
解析：细节题。用international study可定位到第二、三段，第三段中讲到这项国际研究将增加我们对全方位的了解，包括从该地区海冰范围到鱼类种群将如何变化，哪些地区可能成为石油和天然气勘探的目标，以及对该国土生土长的人民的影响。由此可知，这项研究包含了方方面面，故D为正确答案。
3.When he says, \\(A)
A. The migration of the animals to the Arctic.
B. The widespread effects of global warming.
C. The rate of the climate change in the Arctic.
D. The phytoplankton within the marine ecosystem.
解析：指代题。这里需要将上文联系起来看。从第四段的最后一句“behavior can evolve over a long time, but these climate changes are happening in the space of a few decades, rather than hundreds of years”可知，Moore所说的“如此迅速”指的是，因为气候变暖，浮游植物成熟比以往要提前两到三个星期，气候在几十年间的变化导致动物的行为进化跟不上速度，这里的行为进化指的是鱼类洄游到北极，需要几百年的时间才能形成。因此本题正确答案为A。
4.According to the author, to carry out proper human activities in the Arctic________.(D)
A. becomes more difficult than ever before
B. is likely to build a novel economy in the region
C. will surely lower the average world temperature
D. needs the research-based supporting information
解析：细节题。通
