Learning about language

Step1 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.

Step2 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 meaning? Check their meanings in your dictionary. 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. 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.

Step3 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

T: Why is the passive voice used here? When do we usually use passive voice?

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.

Ss: We use has when the recipient of the action is the third person single or single nouns.We use have when the recipient of the action is the first or second person or plural nouns.

After students finish, check the answers.

T: 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

5 The mail has been written.

6 The trees have been planted.

7 The money has been spent.

8 The room has not been booked.

9 The rent has not been paid.

Then deal with activity 3.

T: Read the poem. Underline the use of the present perfect passive voice. Then decide which things have be done well and which have been done badly and what might have happened to the face, hair and shoes and what might have happened to the flowers, grass and pats. You can get cues from the examples.

After students finish, check their work.
