Question

who has bought the book?变被动语态

Answer 1

1. 在口语和书面语表达中，英语比汉语更多地使用被动语态。英语句子由主动语态改为被动语态的结构是：原先的宾语+be+ 谓语动词的过去分词+by + 原先的主语。be的不同变化和主谓语序调整，可以构成被动语态的各个不同的时态。

2. 原句是现在完成时的主动语态，改为被动语态时应保持时态不变。改动后的句子是：

   Whom has the book been bought by?

3. 请看更多的主动句改为被动句的例句：

   Her mother told her to stop watching TV.

   她妈妈告诉她不要看电视了。

   She was told to stop watching TV by her mother.

   她被妈妈告知不能看电视了。

   Everyone thought he was a good young man.

   大家都认为他是一个好青年。

   He was thought to be a good young man by everyone.

   他被大家认为是一个好青年。
