Go over the infinitive

T: In Unit 1 we've learned the infinitive. Please recall the functions of the infinitive.

Ss: Except predicate, the infinitive can function as subject, object, predicative, attribute, adverbial and object compliment.

T: Today we are going to learn more about the infinitive---the infinitive passive.

Explanation of the passive infinitive

to be + past participle,

eg. to be given, to be shut, to be opened

When the grammatical subject of the sentence receives the action, we use the passive infinitive.

For example:

She hates to be laughed at. (others laugh at her--> she is laughed at by others)

I am expecting to be given a pay-rise next month. (give me a pay rise--> I will be given a pay rise.)

be to + passive infinitive (to be + past participle) is often used in notices and instructions.

Examples:

This cover is not to be removed.

The medicine is to be taken three times a day.

To be taken three times a day after meals.

These benches are not to be removed from the changing rooms.

No food of any kind is to be taken into the examination room.

Using structures

Deal with Exercise1-2 on Page14. Ask students to do the exercises one by one. Then continue with the exercises on the workbook. While dealing with Ex2 on page 56, point out to students that "need to be done" has the same meaning as "need doing".
