Great changes ______ in Shanghai since the beginning of the reform and opening-up policy.选项:a、took place b、 has taken place c、 has been taken place d、 have taken place
【答案】D
【解析】
① take place 发生,没有被动语态,所以排除 C
② 句子中 有 since + 时间点,所以用完成时,所以A 排除
③ great changes 是个复数,所以选 D

D
take place "发生' 是不及物动词,没有被动语态
从since the beginning of the reform and opening-up policy可看出应使用现在完成时.

选D

选D,have taken place

答案为D. take place 不能用被动语态,且巨大的变化是由过去发生并且持续到现在的,所以用完成时。
