1. Retelling : revise the main idea of the reading text according to the writing clue(time). T: Boys and girls，let’s begin our today’s class! We can review the reading text of last class. What did we read in the last period of class? (computers, computers’ develpoment) (

Bb writing: Unit 3 Computers)

Yes, we’ve learned something about the history and development of computers. Now who would like to retell the text with the help of these figures (on the screen)? Q: Who can try to retell us the general idea of the reading text WHO AM I ? ( This is the students’

homework. ) PPT：

The development of computers 1642 1822 1936 1940s 1960s 1970s now S: …(While retelling, help the student if necessary.) T: Congratulations! Yes, today it’s true that “Computers have been used by...”

(Bb writing: Computers have been used by ...) 2. Brainstorming: revise some important words and expressions

T: Well done! According to the main information (the development of computers) of the front student’s retelling, and especially the wring clue (computers) of the text, everybody now you can have an enjoyment:

PPT---show the pictures of some aspects of computers develpopment and encourage them to think out enough words about computers in order to review the important words of the unit especially for today’s practice. Q: After enjoying, maybe a lot of words or expressions occur to most of us, who can help us think out some words about computers in English or even in Chinese? S1. … S2. … S3. …S4 …

Ss: Answer together loudly and quickly after showing English one by one. At the same time, try to read and spell each word together in order to remember them.

T: Help the Ss extend more new words and lead them to read. Step 2 Practising Task 1- A quiz 1.With the help of the screen, ask the students to turn to page 20, look at part 1 and choose several students to find out correct words quickly for the following meanings, and then spell them. 2.Give a start and guide them to finish the quick quiz one by one to check their memorizing.

Task2-A test T: Ok. Now we can have a test to use some words to complete a story, please look at part 2, which you’ve learned more about yesterday and we’ve reviewed a lot just now. This short story is about a boy, who is very interested in computers and writing programs. You can have 3mins to finish the passage by yourselves. Q: Can you translate these words into Chinese? (Help the Ss go through all words above the passage together.) Ss: Testing by the Ss themselves freely. T: Ask one student to read and explain the answers together with the passage. S: Explain his\her answers. (Bb writing: some useful expressions - write programs, dowland information, make (good) use of, IT, develop an interest in, in reality) The possible answers：

Q: Who can translate the sentence into Chinese? S: 电脑一直被……人使用。

T: Good. But do you know what the structure of passive voice is and how we can change active voice into its passive voice? You can follow me and look at the screen!

(Bb writing: Active voice→Passive voice)

T: Give an easy example. PPT: Computers are used by billions of people. Q:What’s the structure of the passive voice? Ss: be + past participle (subject→object…) T: Go back to the front sentence.

Q: What’s the structure of the present perfect passive voice? PPT: have + been + past participle T:（analyses）Everyone, please pain more attention!

Q: How can we change the sentence into its active voice?(If you can change the passive voice into an active voice, then it’s easy to change an active voice into a passive voice.) S: Billions of people have used computers.

Q: Ok! Based on the features of the two sentences,what can you find out about these two sentences? S: different opinions. PPT:Passive Voice is better in expressing !

2.Scanning：

T: Ask the students to scan the front reading text Who Am I at P18 and find out sentences about the present perfect passive voice based on their reading after class. S1… S2… S3…

…

PPT:

Over time, I have been changed quite a lot. I have been used in offices and homes since the 1970s.

I never forget anything (that)I have been told. Since the 1970s many new applications have been found for me. I have

also been put

into robots and used

to make mobile phones as well as help with medical operations. I have even been put into space rockets and sent to explore the Moon and Mars. T:While checking answers, help the Ss to find out and analyse the structures of the present perfect passive voice in each sentence. 3.A small test：

Q: Are you clear about the structure of the present perfect passive voice in sentences? (Yes!) T: Now we can choose two of them and ask someone to try to change them into their active voice? S1…S2…(Try to help the Ss find out the subject of each passive voice.) 1)I have been used in offices and homes since the 1970s.→People/They have used me(computers) in…

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

→Since the 1970s people/they have found many new applications for me. T: Let’s have a small test, who can try to change this sentence into its passive voice ? S1… S2…

PPT: Have you sent for your father ? →Has your father been sent for (by you)? T: Perfect! You’ve finished them perfectly. Now can you simply use the present perfect passive voice to make simple sentences ? (Yes!)

Task 4-Writing 1.Guiding: T: Good. Now let’s turn to page 20 and look at part 3. It’s today’s difficult part. Can you find out how the story is developed? or what is the outline of the wrting？And what’s the tense and voice for each sentence?

Ss: …( time order)…Skim the structure of the story on the screenm. PPT: When I was young At the time Over time

As time went by By the time As a result From then on……………………………………………. 一般过去时

过去进行时

T: Explain the task of writing and guide the students. 2.Writing: T: Now We can start our small groups of four students!

Ss: discuss…and then start to create stories.

T: Ask one or two leaders to show their stories on the screen. And discuss their qualities and how they can be improved further together.(Because of time, the other groups you can exchange your stories after class. In your spare time, if you have interest you can practise writing more like this.) Step 3 Summary and homework This class we’ve revised some important words and expressions, and also simply studied the present perfect passive voice, and even we have practised writing using different tenses in time order, especially we kown how to use the present perfect passive voice to write sentences.
