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.

[br] 【C2】
选项 A、corporations
B、firms
C、foundations
D、institutions
答案 D
解析 空格处指前一句中的universitiesand research laboratories，因此应该用institutions“(大学、银行等大规模的)机构”指代大学和研究实验室。corporations意为“股份公司”；firms意为“商行；公司”；foundations意为“基金会”。这三项均不符合大学和研究实验室的性质。
