Step ⅠRevision

Ask students to tell the characteristics of science fiction.

Step ⅡWord study

Deal with exercises about useful words and expressions. When doing Ex1 and Ex3 on Page 13, students may use an English-English dictionary so that they can understand the situations where the words are used.

Ex1 will help students to form the habit of thinking in English.

Ex2 will help students to master the useful words and phrases in context.

Ex3 will help students to learn more about word formation and use the words in proper situations. After dealing with Ex3, point out words like alarmed are adjectives, when following the link verb be, it is used to describe a feeling. Sentences that have such structures are not passive.

T: Look at the following sentence: My mother felt alarmed when I had my hair coloured purple. If I use was to replace felt, the sentence will be: My mother was alarmed when I had my hair coloured purple. Is this a passive sentence?

Ss: No. Though the structure seems like a passive sentence, it is not. A passive sentence indicates a passive action while this sentence describes a situation when someone has the feeling of alarm. “Alarmed” is an adjective formed by v+ed.

T: Quite good. Please remember not all be + v +-ed /-en / -t sentences are passive.

Step ⅢGrammar study

Go over the passive voice: be + v +-ed / -en / -t

T: Please give some examples of passive sentences.

S1: My homework was eaten by the dog.

S2: The toy is made by hand.

...

T: Good. Please remember the passive is formed with any time frame of the verb.
