Step2. Discovering useful words and expressions 本单元词汇练习有三个部分。

练习1

单词释义。在处理时进行了调整，把这一部分设计为一个小活动，让两个学生一个说出单词的释义，另一个猜单词，让他们通过英文释义理解单词，同时也是对词汇学习的一个热身活动。

1.Find the word or expressions for each of the following meanings from the text. (Guessing game: one partner tells the meaning of the word or uses body language to describe the word, the other one guess which word it is.) 1.___________complete change in ways of thinking ,working , etc. 2.___________

练习2

是部分重点课标词在语篇中的应用。让学生先熟悉所提供的词汇，再通过阅读，依据语篇，考虑选词，训练学生的整体阅读能力。

2.Complete the passage with the words below.

After developing special ___________ of the computer, he hopes to design an __________ robot which can think _________ and look like a human being, but in _______ he has a long way to go.

练习3

是对课文中出现的重点时间短语的复习，题目用语篇的形式把这些短语连接起来，“摆弄收音机”这个爱好如何改变一个人的一生，对学生有一定的启迪作用。语言输出为仿写自己的故事。

本环节设计了两个活动。

活动一：教师示范，学生倾听、感悟。内容改写自学生非常熟悉的课文，用这些重点时间短语串起来，语言生动活泼，学生自己的写作能力也能达到，更贴近学生的水平，启发他们也尝试改写课文，逐步提高运用语言的能力。

活动二：小组活动，依据时间短语编故事。这个任务有一定的难度。在活动中采取了合作学习，相互交流，共同进步，集中呈现的方法，培养学生学会与人沟通，协调合作的能力。然后请几位学生把自己编写的故事分享给大家，大家一起欣赏和评价这几位同学的故事编写是否成功。

3.Read the story and then use the outline to create one of your own.

My

Story When I was young , I was crazy about radios. At the time my interest began, I was playing with radios at home. Over time, I decided to build my own radio. As time went by, I did research into how to make my radio. By the time I was sixteen, my dream had come true. I made my own radio. As a result, I became interested in electronics and computers. From then on, I worked hard to get into university. Now I am working in a computer company designing new programs for computers. As I grow older, I realized how much my life has been connected with my interest in radios!

Teacher’s

Story

When I was young , I was crazy about English. At the time my interest began, I was listening to English programs in radio. Over time, I decided to buy my own walkman (随声听)to learn English. As time went by, I made great progress in learning English. By the time I was eighteen, my dream had come true. I became an English major in a teachers’ college.

As a result, I became an English teacher. From then on, I worked hard to teach English. Now I am working as an English teacher in Wuhan No.1 High School. As I grow older, I realized how much my life has been connected with English.

From then on_______________________________________________________________. Now ______________________________________________________________________.

Step3. The Present Perfect Passive Voice

语法学习也有三个部分。

第一部分：依据所给例句，让学生在文章中再找出几个这样的句子，这一设计体现了探究性学习的理念，让学生对足够的语言输入理解后自己去发现总结。

1. Look at the following sentence, paying attention to the underlined part.

Example: Over time I have been changed a lot.

3

Can you pick out more than two sentences in the present perfect passive voice

from the reading passage?

1) Since the 1970s, many new applications have been found for me.

2) I have also been put into robots and used to make mobile phones as well as

help with medical operations.

3) I have been put into space rockets and sent to explore the Moon and Mars.

第二部分：句型操练。这是非常有效的专项训练。

2.Change the following sentences into the present perfect passive voice.

Example: We have made a plan.

A plan has been made.

1) My friend has bought a new personal computer.

2) The shop has repaired my computer very quickly.

3) An unknown virus has just attacked my computer.

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.

第三部分：语法的再次呈现，语法项目的真实运用。

这个环节中，对教材内容进行了部分调整和删减。为了活动的展开，用Workbook 中57页的第三部分替换了Discovering useful structures中的第三部分。

本环节设计了两个活动，采用了“meaningful, contextualized, interactive”的原则和“探究---感知---归纳---合作---呈现”的训练模式。

活动一：小组活动。

把同学分为四人一组，结对活动，组句成段。遵循学生个体差异的原则，让每个学生都有习得的体验。没有硬性要求，能力较强的学生可使用全部句子，能力相对较逊的学生可尽量多地使用。同时在活动中也体现沟通、合作和共同学习的理念。在这个活动中增加了学生互评的环节，让学生体验如何评价朋友，体会成功的快乐，意识到需要改进的地方，培养健康的人文观念。

活动二：角色扮演，颁奖典礼。让学生直观体会到现在完成时的被动语态的常用场合，创设真实情境，激活所学语言，达到学习目的。

3. The present perfect passive voice is often used in formal situations such as articles or speeches. The headmaster is making a speech. Help him

complete his speech using the present perfect passive voice.
