to have done 是不定式的完成结构 表示这个动作发生在谓语动作之前 所以要用完成结构He is said to have lost his car.比如这个句子的谓语动词的 is said 但是 lose his car 这一动作发生在谓语动词 said 之前 所以非谓语要用 完成式======以下答案可供参考======供参考答案1:英语中to have done 表示发生在谓语动词之前的动作eg . He seemed to have seen the film . He is said to have gone abroad to study .供参考答案2:I go out to have my hair cut. 这个答案行不行
