Teaching procedures

Step 1 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 2 Reading and finding

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? 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 3 Discover 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

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.

After students finish, check the answers.
