Great changes______ in our country since 1980.填have been taken place还是填have taken place再说下理由.
问题描述：
Great changes______ in our country since 1980.
填have been taken place
还是填have taken place
再说下理由.
答
have taken place，因为take place和主语changes是主谓的关系，这个短语是没有被动语态的。
答
have taken place
take place没有被动语态的
答
填have taken place
因为take place（发生vt.）的主语就是动作发出者本身,没有被动的说法.例如：昨天在这发生了一场地震 An earthquake took place here.
类似的动词：taste,It tasts good.(它尝起来不错),它是“被尝”,但也不用被动,依然是主动.
