Learning about language

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教材分析

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；

（2）是根据例句提示把所给的现在完成时句子变为被动语；

（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。

Step II

Lead in

T: Let us read the vocabulary. Read after me.

T: Every word has its own meaning and usage. Now let us learn these words. Step III

教学环节

课堂讲授

Check the answers. Explain some important words: simplify; solve; explore; totally; anyhow. 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.

Explain some important phrases: be interested in; enjoy doing sth. ; make good use of; IT ; in reality. T: Now activity 3. Look at the story. What do they have in common? T: 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 correct for each other and then choose someone to read it.

Step IV Discovering useful structures

Let students find sentences in the present perfect passive voice（现在完成时的被动语态）

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 the present perfect passive voice tense. Elicit the structure: S + have/has + been + done eg: The experiment has been done successfully. T: Why is the passive voice used here? When do we usually use passive voice? Ss: …

T: The passive voice is used when the subject of a sentence is the person or thing affected by the action of the sentence. We particular use the passive voice when don’t know or aren’t bothered exactly who has done something. Now look at activity 2. Change the sentences into the present perfect passive voice. Pay attention to the use of has/have. When do we use has and when do we use have? After students finish, check the answers.

EXERCISE. 1、the postcard / send __________________________ 2、the door / close _____________________________

3、the trees / plant ____________________________

4、the people / inform / not _______________________ Then 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.
