五．Learning about language 分析：

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

1.

Discovering useful words and expressions ：

（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。

2. Discovering useful structures 是学习现在完成时的被动语态。

（1）是让学生根据例子提示在WHO AM I?文章中找出两个含有现在完成时的被动语态的句子，初步了解这一时态的形式。

（2是根据例句提示把所给的现在完成时句子变为被动语态。

Integrative skills (II) Teaching procedures & ways ：

Step I：

Revision Check the homework. Ask two students to read the passage they have written. Their passage should be brief and include the key information or facts about the development of computers.

Step II：

Discovering useful words and expressions T: Look at activity 1. These are the meanings of some words or expressions in the text we learned yesterday. Find out these words or expressions.

Check the answers.

T: Now look at the words in activity 2. Do you know their meanings? Check their meanings in your dictionaries. Then complete the passage with the words.

Check the answers.

T: Now activity 3. Look at the phrases in bold in the story. What do they have in common? S: They are all time phrases except “as a result”. They are used in the passage to indicate the development of the story. From them, we get

a clear timeline of the story. T: Correct! Now use these phrases to create one of your own stories. The story can be a real one or an imaginary one.

After they finish writing, let students exchange their stories and proofread for each other.

Step III ：Discovering useful structures

Let students find sentences in the present perfect passive voice in the text and then

analyze their form and function. (activity 1 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.

Then let students study these sentences carefully and sum up the form of present perfect passive voice tense. Elicit the structure: S + have/has + been + V-ed Step IV:

Practice the present perfect passive voice:

Now write passive sentences in Present Perfect according to the words given. Show the following on the screen. 1 the postcard / send __________________________ 2 the pencils / count ___________________________ 3 the door / close _____________________________ 4 the beds / make _____________________________ 5 the mail / write _____________________________ 6 the trees / plant _____________________________ 7 the money / spend ___________________________ 8 the room / book / not _________________________ 9 the rent / pay / not ___________________________ 10 the people / inform / not _______________________ Check the answers together with the students StepV: Assignment: 1. 复习第三单元的单词和短语。

2.复习现在完成时的被动语态的构成和用法。

3. Practice the exercise.
