Unit3 Computers ——Learning about language 教材分析：

Learning about language分词汇(Discovering useful words and expressions)和语法(Discovering useful structures)两大部分：

其中Discovering useful words and expressions 分为三个小部分：1

根据单词释义写出相对应的词汇，考查学生对WHO

AM

I?

文章中的重要词汇及短语的理解。2

是以对短文填词完型的形式考查学生对几个重点词汇在篇章中的运用。3以personalize的形式练习几个表时间状语的短语的用法。Discovering

useful

structures

是学习现在完成时的被动语态，也分为三个小部分：1

是让学生根据例子提示在文章中找出两个含有现在完成时的被动语态的句子，进而让他们对这个时态的形式有初步了解。2

是首先给出一个将现在完成时变为被动语态的例子，然后根据例句提示把所给的六个句子变为被动语态。3

通过欣赏一首小诗进一步理解现在完成时的被动语态的用法。

学情分析：

本单元的主题是Computers，介绍计算机的发展历程和现代计算机的工作原理。现在完成时的被动语态是本单元的语法。在这之前，学生已经学习并掌握了一般现在时态，现在完成时态和被动语态的用法，为学好此部分打好了基础。

Ex3. You can exchange your sentences, and then discuss with your partner to help each other find out some faults in two minutes. After that two students will speak out their words. Some students stand up and speak out their sentences positively. Step 2: Discovering useful structures

Task1 T:

Observe the following sentences, and find if there is

something in common. (Help them to learn the useful structure: the Present Perfect Passive Voice.) (1)Over time I have been changed quite a lot. (2)That book has been translated into at least 12 foreign languages. The students discover whether these sentences have something in common. S: They are both the Present Perfect Tense. T: Are there any differences? S: The first sentence is the Active Voice, and the second is the Passive Voice. Task2 Let the students find some sentences in the present perfect passive voice in the text and then analyze their form and function. (on page 21.) Students may find the following sentences: 1、 I have been used in offices and homes since the 1970s. 2、Over time my memory has developed so much that, like an elephant, I never forget anything I have been told! 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 as well as help with medical operations. 5、I have even been put into space rockets and sent to explore the Moon and Mars. Task3 Let the students study these sentences carefully and sum up the form of present perfect passive voice tense. Step3 Elicit the structure:

S + have/has + been + V-ed

Give them some explanations：

1 引导学生复习一般现在时、现在完成时和主动被动语态的知识。

2现在完成被动语态的构成：

主动语态 被动语态

现在完成时 have/has done----------have/has been done These books have been read lately. He has been sent to study the new technology in the company. The dirty clothes have not been washed. Have the windows been cleaned? Where has the car been repaired? Who have been helped by the new computer? How many buildings have been built in this school? 3.强调

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? 4．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 Then give the five minutes to discuss and learn the structure. 5、 Change the sentences into the present perfect passive voice. Pay attention to the usage of has/have. After students finish, the teacher help them check the answers. T: Now write passive sentences in Present Perfect according to the words given. 6、Show the following on the screen. （1） The buildings, destroy, in the earthquake __________________________ （2） The door, close ___________________________ （3）A new bridge, build, in our city

___________________________ （4）the trees ,plant ___________________________ （5）the room ,book, not ________________________ Answers: （1）The buildings have been destroyed in the earthquake. （2）The door has been closed. （3）A new bridge has been built in our city （4）The trees have been planted. （5）The room has not been booked. 7、Deal with activity 3. T: Read the poem. Underline the use of the present perfect passive voice. Then decide which things have been done well and which have been done badly. Guess what might have happened to the face, hair and shoes and what might have happened to the flowers, grass and paths. You can get cues from the examples. After students finish, check their work. T: Which words in the poem rhymes? Ss: washed, combed, cleaned, planted, cut, swept, again, again. T: Right! Please write your own poem with similar rhythm and

intonation after class. Step4: Practice and exercises 1. Change the following sentences into the Present Perfect Passive Voice. (1). We have completed all the preparations for the task, and we’re ready to start.
