As time had gone by, I have been made smaller and smaller.

I have been used in offices and homes since the 1970s.

Over time my memory has developed so much that, like an elephant, I never forget anything 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.

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 Listen to the text again and do Exercise 1and 2 on Page 20

Check the answers. Deal with the problems that arise in the exercises.

Activity 3. My story

Ask the students to read the story quickly and pay more attention to the phrases in bold . Discuss “What do they have in common?”

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.

Task: 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 Explain to the students when to use the perfect

passive voice tense and

when to use “have or”.

Step IV

Practice

Do exercise 2 on Page 21.After students finish, check the answers.

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.

Then get them to write a similar poem following the rhythm and intonation.

Homework.

Write their own poem with similar rhythm and intonation. After they finish, exchange with their partners and check for each other. Pay attention to the rhythm and grammar.
