主语＋have/has not been done... 一般疑问式

Have/Has＋主语＋been done...？

特殊疑问式

疑问词＋have/has＋主语＋been done...？

三．使用现在完成时的被动语态要注意以下几点

1．现在完成时的被动语态的两个助动词，即have/has 和

been，两者缺一不可。

2．与一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联系，而现在完成时的被动语态则强调与现在情况的联系。

This novel was finished last year. 这部小说是去年完成的。

This novel has been finished. 这部小说已经完成了。

3．一些特殊动词，如borrow，finish，begin，buy，start，return，marry，open，join等构成的现在完成时的被动语态不能与表示一段时间的状语连用。

4．用在时间或条件状语从句中，表示将来某时要完成的动作，即用现在完成时的被动语态代替将来完成时的被动语态。

You can go home as soon as your task has been finished.你的任务一完成你就可以回家了。
