yesterday可以连用完成时态吗

问题描述

He is said to have read two books yesterday.

昨天是过去时，前面的 is said to have read 不是完成时吗？这句话时态对吗？

老师答疑

龙老师：

句子没有任何问题。因为句子中的 yesterday 是修饰不定式完成式的。

句子意思是：据说他昨天读了两本书。

注意以下同义转换：

He is said to have read two books yesterday. 据说他昨天读了两本书。

= It is said that read two books yesterday. 据说他昨天读了两本书。

又如：

Everything seems to have been built yesterday. 好像一切都是昨天才建成的。

He is believed to have crossed the frontier last night. 相信他昨天晚上已经越过了边界。
