1.A for 后面跟的成分表原因，只有have been done和not have been done 没有 have not been done 这种说法。2.C based 引导的成分做独立主格结构，基于一个德国童话，如果选A的话句子中就有两个系动词is，就不能组成句子了！

A。非谓语动词的否定式在结构前直接加not。楼上还没搞清楚动词的时态语态和非谓语动词的时态语态吧。C。前面部分是完整的句子，一个句子不能出现两个谓语动词，故A错。C项based是过去分词作后置定语，相当于一个定语从句：Swan Lake is a famous ballet in four acts,which is based on a German
