[疑问式]

[特殊疑问式]

②The work has already been finished.

2. 表示一个被动的动作或状态开始于过去，持续到现在，并有可能持续下去，常与for或since引导的时间状语连用，或用于How long...句型中。

The plan has been discussed for nearly 2 hours.这项计划已被讨论近两个小时了。

3．用在时间或条件状语从句中，表示将来某时已完成的动作，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.

你完成任务就可以回家。

注意：1. 现在完成时的被动语态强调过去发生的事与现在有联系；而一般过去时的被动语态所表示的动作只与过去有关，与现在没有关系。

这座图书馆已经建好了。(图书馆可以用了)

②The library was built last year.

这座图书馆是去年建成的。(图书馆现在是否能用是未知的)

2. 含有非延续性动词(如begin，start，buy，borrow，finish等的现在完成时的被动语态的肯定式)不能与表示一段时间的状语连用。这些动词的现在完成时的被动语态的否定式则可以与for或since构成的时间状语连用。

The work has been finished for two days.

This book has not been borrowed since last week.

3. 动词短语用于现在完成时的被动语态时，动词后面的副词或介词不可漏掉或省略。

The injured bird has been looked after since it was saved.

教学反思：

通过这节课，学生能复习巩固本单元的重点词汇。学生对现在完成时的被动语态有一定的了解。最后，通过练习对整节课的语法知识进行反馈，了解学生的接受程度和理解的程度。

不足：1、在task2环节，由于时间关系，讲的不够具体。在class exercise环节，

教师没有多问一些同学，让学生发散思维，并把学生提到的答案板书黑板，逐一讲解。整节课，留给学生思考的空间和时间都不够。

希望在以后教学中，教学设计更加接地气，更加调动学生的参与度，给予学生足够的时间思考和做该做的笔记，让学生多讲多思考。
