Get the key words and phrases in these two exercises and summarize how to use them. 设计意图：该部分学生通过group-discussion的方式学,在小组里面各抒己见，自行解决消化相关知识点，有趣而易接受。同时通过小组讨论，还可节约时间，老师重点讲解重难点，大大提高课堂效率。

Step 2 present perfect passive voice 1.

名称：

什么时候用被动：

什么时候用现在完成时（主+被）？有什么样的标志？

现在完成时被动语态的形式有哪些？

设计意图

：教师首先通过例子的观察让学生总结出该部分的重点-----现在完成时的被动语态。通过学生自行观察得出的结论，学生更容易接受，也易于记忆。老师再进行部分知识点的提问，通过例子，让学生知道该知识点的重点，全面掌握现在完成时被动语态。

Step 3 solve the difficult points 1．现在完成时的被动语态的助动词，即have/has和been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的情况有联系。

3．非延续性动词，如borrow，finish，begin，start，buy，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。若要表达相应的意思，则要改换动词或时态。

设计意图：重难点一般也是高考的考察点，通过学生的观察和专项讲解，让学生进一步掌握，同时进一步强调其重要性。
