问题描述：
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
选D
答
选D,have taken place
答
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。
答
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.
答
【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
