In this class, I will use inductive method and cooperative method. Part 6 Teaching Procedure

Step 1: Revision and lead-in

Task 1 T：Please turn to Page 20 and finish Discovering useful words and expressions. At first，look at Ex.1.From the reading passage，find the words and expressions with the following meanings. Now，ten students will be asked to give the words. Who can? Volunteers! Check the answers together. Task 2 T：Well done. Now please look at Ex 2. and complete the passage with some of the words above. Pay attention to the use and the forms of those words. Task 3 T：Please finish Ex.3.Look at the sentences on Page 20.Tick the right word. Then some of you will be asked to read the sentences one by one. Step 2: Discovering

Boys and girls, In last class, we learned about the history and development of computers, read the passage again, and then find out these the Present Perfect Passive Voice sentences in the passage.

Step3: Discussion : learning the structure 1. Compare

She has taken my exercise-books away．她已拿走了我练习本。

My exercise-books have been taken away．我的练习本被拿走了

2. the Present Perfect Passive Voice 2.1 have / has ＋

been＋~ed 现在完成时的被动语态表示动作发生在过去, 到现在已经完成或对现在仍有影响。

主动语态即主语为动作的执行者；被动语态即主语为动作的承受者。现在完成时的被动语态同它的主动语态一样，强调过去的动作对现在造成的影响或结果，但主语为动作的承受者，表示“……已经被……”。

1). 现在完成时被动语态的肯定式为：have / has + been + done

2). 现在完成时被动语态的否定式为have / has + not + been + done

3). 现在完成时被动语态的一般疑问句需将have / has提到主语的前面

4). 现在完成时被动语态的特殊疑问句为：疑问词

+ have / has + been + done 只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place, die, appear, disappear, fail, remain, lie, last, sit ,stand, break out, come true, belong to等．如：

What has happened to your brother? 但许多不及物动词加介词或副词构成的短语动词，相当于及物动词，也可以有被动语态。但短语动词是一个不可分割的整体，变为被动语态时，不可丢掉构成短语的介词或副词。如：

The child has been taken good care of by Grandma Wang all these years. A notice has been put up on the wall 2.2 现在完成时的被动语态表达以下两个概念：

1). 说话时已经完成的动作或出现的结果。

2). 主语是行为动作的承受者。

2.3. 主动语态变被动语态的方法

将主动语态改为被动语态应注意以下三个方面：①将主动语态的宾语改为被动语态的主语；②将主动语态的谓语动词改为“be＋过去分词”结构；③将主动语态的主语改为介词by之后的宾语，放在谓语动词之后（有时可省略）

一般情况要熟记，“be+过去分词”常用起，过去现在只变be,将来时态更易记，前面用上will/would 即，情态动词大家族，写在其前就完毕，完成时态不难记，have/had been + 过去分词，进行时态要留意，be being + 过去分词，特殊情况要心细，感官、使役to 提起，如遇介、副小短语，转换之中别丢弃，找准主、谓、宾三弟，做题轻松又如意。

Step 3: Exercise for consolidation. Students try to do the exercise 2 on page 21, then teacher give guidance and check. Step4. Summary and Homework After the task, I will ask students to conclude what we have learned today, the Present Perfect Passive Voice then I will set homework. Part 7 Homework

Ask the students to finish the exercises on page 7 of exercise book.

Part 8 Blackboard Design. 1构成：

主动语态

被动语态

现在完成时

have/has done----------have/has been done 2. 只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place,

die, appear, disappear, fail, remain, lie, last, sit ,stand, break out, come true, belong to等．如：

What has happened to your brother? 3.记忆口诀

一般情况要熟记，“be+过去分词”常用起，过去现在只变be,将来时态更易记，前面用上will/would 即，情态动词大家族，写在其前就完毕，完成时态不难记，have/had been + 过去分词，进行时态要留意，be being + 过去分词，特殊情况要心细，感官、使役to 提起，如遇介、副小短语，转换之中别丢弃，找准主、谓、宾三弟，做题轻松又如意。
