    SA : What are they used for?
    SB: They're used for seeing in the dark.
    Get the students to ask about the three inventions first, using the information in the chart in Activity 2b.
    Then let them role play the conversations using the information in the chart in Activity 2c.
    Get them to make their own conversations using the information in the chart in Activity 2c like this:
    (Pointing to the inventions)
    A: What are these?
    B: They are battery-operated slippers.
    A: What are they used for?
    B: They are used for seeing in the dark.
    A: Who were they invented by?
    B: They were invented by Julie Thompson.
    Ask the students to work in pairs. Move around the classroom checking progress and providing help if needed.
    Check the answers by calling on different pairs to say their conversations for the class.
    Step Ⅴ Grammar Focus
    This activity introduces the target language with the Passive Voice.
    Call the students' attention to the sentences in the grammar box.
    Ask four pairs of the students to read the questions and answers in the grammar box.
    SA: When was the car invented ?
    SB: It was invented in 1885.
    SA: When were electric slippers invented?
    SB: They were invented last year.
    SA : Who were they invented by?
    SB: They were invented by Julie Thompson.
    SA: What were they used for?
    SB: They were used for seeing in the dark.
    Write them on the blackboard.
    Let the student think about the structures of these sentences.
    Tell them that when the subject of the sentence is the doer, we have to use be plus a past participle' as the predicate of the sentence.
    Circle the words was and were in all the sentences.
    Ask: When do we use was in the questions, and were in the questions?
    Underline the singular nouns and plural nouns.
    Singular items like car use the singular verb was. Plural items like slippers use the plural verb were.
    Circle the word invented in all the sentences.
    You always use a past participle when you use was plus a verb or were plus a verb. And you can tell the doer with by. Say something about be used for to the children.
