[设计意图]：全班通过大声齐读句子来进行上课前的热身，使学生集中注意力，快速地融入课堂；教师通过挑选句子嵌入本节课要学习的重点词汇，让学生在句子中学习单词；也为下一部分的练习做好准备。

[设计意图]：此部分是课本里的练习题，教师引导学生做题前，全班大声齐读单词，说出对应的单词意思，再把符合题目要求的单词表达填进空格中，同时，也为下一部分做铺垫。

StepⅡ. Discovering useful structures.

Activity 1. My story [设计意图]：这个短文是根据课文里出现的小短文改写的，联系上一部分，教师说：just now we have learned the story of my brother, today I want to share my story with you!通过改写教师个人的经历目的是为了吸引学生的兴趣，以正面的例子对学生言传身教，落实立德树人的教育目的；同时引导学生利用课本所给的提示，写一篇自己的小故事（这个任务放在课后任务---Write a passage about your story by using the time order.）。

As I grew older I realize how much my life has been connected with my interest in English! [设计意图]：短文最后一句话中嵌套了接下来要学习的语法，教师在上课过程中会提醒学生引起重视。

Let's find more examples in the text: 1. Over time I have been changed quite a lot.

2. I have been used in offices and homes since 1970s.

3. Since the 1970s many new applications have been found for me.

4. I have also been put into robots and used to make mobile phones ......

5. I have even been put into space rockets and sent to explore the Moon and Mars.

[设计意图]：请学生在阅读篇章中找出包含有现在完成时的被动的句子，再次快速阅读加深对语篇内容的理解，同时学生在寻找的过程中，植入语法概念。

Activity 2. Discuss with desk-mates to find out the structures of the sentences. The present perfect

The passive voice

(after discussion, ask some students to write the notes on blackboard.) [设计意图]：请学生之间互相讨论，总结归纳出语法点，并请部分学生上黑板展示讨论的成果，把课堂的主动权交给学生。

Activity 3. Learning about the The present perfect passive voice. 1.

概念(The concept)：

(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。

Example: I ____________(tell) about it many times．

The bridge ________________(build)．

Exercise 1. Change the following sentences into the present perfect passive voice. Example: We have made a plan. →

A plan has been made (by us). 1.

My friend has bought a new personal computer.

→_______________________________________ 2.

→______________________________________ 4.

We have not solved the problem yet.

→__________________________________________________ 5.

The company has given its computers away to a local school.

→______________________________ 6.

The scientists have developed a kind of intelligent robot.

→_________________________________ [设计意图]：教师点评归纳语法概念，通过改写句子的练习，加深学生对概念的理解。

2. 句型(the sentence patterns) (1). 现在完成时被动语态肯定句句型：

These trees ________________(water) lately.

(2). 现在完成时被动语态否定句句型：

The task _____________________(finish) yet.

Many workers_____________________（train) in the company. (3). 现在完成时被动语态一般疑问句句型：

Have they been sent abroad to study English? (4). 现在完成时被动语态特殊疑问句句型：

Where has the car been repaired? Who have been helped by the new computer?

How many buildings have been built in this school?

[设计意图]：教师讲解相关句型后，学生及时操练。

3.用法(The usages) (1). 现在完成时的被动语态同他的主动语态一样，

强调过去的动作对现在造成的影响或后果与already,yet, just, never, recently 等副词(常放在have或has之后)连用。

(2). 表示一个被动的动作或状态开始于过去,持续到现在,并可能持续下去,常与

for 或since引导的时间状语连用,或用于How long...?句型中。

(3). 注意事项: a. 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。例如: happen, take place, die, appear, disappear, fail, remain, lie, last, sit, stand,

break out, come true, belong to等。b. 但许多不及物动词加介词或副词构成的动词短语，相当于及物

动词，也可以有被动语态。但动词短语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。
