题型：不详难度：来源：
The population of this city ,forty percent of which_____, ______ 15% in the last three years| A．are Germans, has risen by | | B．are Germen, has fallen by | | C．is Germans, have been increased by | | D．is Germen, have been reduced by |
|
答案
| A |
解析
试题分析：考查population的用法以及主谓一致。句意：这个城市的人口40%是德国人，在过去的三年中已经增加了15%。population强调人口是多少时，若作主语，谓语动词用单数形式。population强调人口的身份或特征，若后面作表语的名词是复数时，谓语动词则要用复数形式。据题意，第一空中Germans 用复数，则谓语动词用复数，Ｂ、Ｃ两项可排除，而the population of this city强调人口，谓语动词需用单数，故本题最佳答案为Ａ。 |
