问题     The Antarctic ozone(臭氧)hole is changing weather patterns across the Southern Hemisphere(半球), even affecting the tropics, scientists have concluded. The scientists【C1】______the new study added the ozone hole into standard climate models to【C2】______how it might have affected winds and rains. They say rainfall has moved further south【C3】______the pole and the effect has been【C4】______strong over Australia.
    And of【C5】______interest was the southward of the Southern Hemisphere jet stream. These high-altitude winds are【C6】______to determining weather patterns, in both hemispheres. Much of the cold weather felt in the UK【C7】______the last couple of winters, for example, was【C8】______by blocking of the Northern Hemisphere stream.
    The team found that overall, the ozone hole has【C9】______in rainfall moving south along with the winds.【C10】______there are regional differences, particularly concerning Australia. In【C11】______of the average for that zone, the ozone hole【C12】______about a 10% change—but for Australia, it’s about 35%.
    Their modeling indicated that global warming【C13】______greenhouse gas emissions is also a factor in changing rainfall patterns.
    Natural climate cycles are also thought to be important here, as different rainfall patterns were【C14】______in the era before ozone depletion(消耗)and【C15】______20th Century warming.
    Although the【C16】______international organization has significantly checked emissions of harmful substances, they【C17】______for decades in the atmosphere, and so their effects are still being felt. Earlier, an international organization【C18】______that even the Antarctic ozone hole—which is more severe than its【C19】______in the Northern Hemisphere—should be【C20】______by 2045-60.
【C11】
选项 A、views
B、respects
C、terms
D、cases
答案C
解析 考查固定搭配。in terms of“在……方面”，符合语境。注意其他选项的单词用于这种句式时，都应该是单数形式。in view of“鉴于，考虑到”，in respect of“涉及，关于”，in case of“假如”。
