　　A,inform

　　B.informing

　　C.informed

　　D.to be informed

　　【参考答案】C。本题考查分词的用法。分词可以作宾语补足语，因为宾语与分词之间是被动关系，所以要用过去分词。

　　20.You could have done much better yesterday.Why (　　)?

　　A.didn't you

　　B.couldn't you

　　C.hadn't you

　　D.shouldn't you

　　【参考答案】A。本题考查动词时态的用法。第一个句子用了虚拟语气，表示与过去事实相反，所以后面的特殊疑问句应该使用正常的语气。这里应用一般过去时。
