Mr. Obama says that part of the solution【C1】______America’s economic problems should come from its universities and research laboratories. Yet these【C2】______in America are now manned disproportionately(不均衡地)by immigrants, who made【C3】______47% of scientists and engineers in America with PhDs. William Kerr, an economist at Harvard Business School, used name-matching software to【C4】______the ethnicity(种族)of each of the 8 million scientists who h ad【C5】______an American patent since 1975. He found that the share of patents【C6】______to scientists born in America【C7】______between 1975 and 2004. The share of all patents given to scientists of Chinese and Indian【C8】______living n America more than tripled,【C9】______4.1% in the second half of the 1970s to 13. 9% in the【C10】______between 2000 and 2004. Some of these patents may have been given to American-born children of earlier【C11】______, but Mr. Kerr reckons that most changes over time【C12】______from fresh immigration.

选项
A、fell
B、extended
C、enlarged
D、rose
答案
A
解析
本文讲述的是移民科学家对美国做出的贡献,由此推断,此句讲述的是与移民科学家相比,近年来美国本土科学家得到的专利份额减少了。主句的时态是一般过去时,所以空格处应该用fall“下跌”的过去式fell。
