      新課導入

      Language practice

      Reuse means “use again”.

      Though pollution is heavy now, I don’t think it’s hopeless.

      新課講解

      Make new words. Join the parts of words in Box A with the words in Box B. You need to use some of the parts more than once.

      We shouldn’t use  disposable food box or disposable chopsticks. 

      These are some bowls and spoons made of china.

      Someone threw an empty bottle in a river.

      There are three rubbish bins for recycling, so please divide the waste before you throw things into them. 

      Possible answers:

      It is better to use china cups and bowls because they can be used many times.

      It is better to divide the waste into things to recycle and things to throw away.

      It is necessary to use less plastic bags.

      You should make a recycling policy for your classmates and yourself.

      Language points 

      It is better to use china cups and bowls...

      用瓷杯和瓷碗更好…… it在這里作形式主語。 

      作不定式的形式主語

      eg:It's not easy to get him to change his mind. 讓他改變主意不容易。

      作that引導的從句的形式主語

      eg:It is obvious that we can't go on like this.我們顯然不能像這樣繼續了

      作whether, when, what等引導的句子的形式主語

      eg:It doesn't matter whether you go or not. 你去不去沒關系。

      作動名詞的形式主語

      eg:It was nice seeing you. 看見你真好。

      when shopping 當買東西時

      when+doing,when為連詞,由于主句和從句主語相同,故可省略從句中的主語和be動詞。

      eg:When waiting for the train, he always plays his mobile games.

      當他等火車時,他總是玩他的手機游戲。

      ... ... ...
