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、return
B、leave
C、refuse
D、withdraw
答案
B
解析
have sb. do sth.意为“允许/让某人做某事”,为常用结构,因此many scientists后面应接动词原形。句子意思是“允许大量科学家______印度的确会削弱那里的创新能力”,结合四个选项,只有leave“离开”符合句意。return“回来,返回”和refuse“拒绝”均不符合句意;withdraw意为“撤退,退出”,和介词from连用,也不符合句意。
