A.is said to be buying B.is said to have bought
C.had said to buy D.has said to have bought
发生在谓语动词之前不是应该用had .为什么答案要用have.
A.is said to be buying B.is said to have bought
C.had said to buy D.has said to have bought
发生在谓语动词之前不是应该用had .为什么答案要用have.
/>1 be said to have done sth :发生在谓语动词之前,to是动词原形的标志,所以to后面用动词原形
2 be said to +动词原形
3 相同的结构还有
be thought to
be believed to + do / be done
be reported to + be doing
be considered to + have( been) done
be known to
be found to
再问： 不是说句子里有两个谓语动词时先发生的用had done吗？
再答： 你好。因为有了谓语动词，比如说，be found to ，后面就要用完成式的原形： I find that he was here last week. --------- == He is found to have been here last week. (仔细研读，你就明白了。祝你愉快。)
