Teaching procedures: Step1 Greeting and revision 非谓语动词三种形式：to do,v-ing,done以及V-ing 变化规则

1. 直接加ing 2. 去e加ing 3. 以重读闭音节结尾的动词，双写辅音字母加ing Step2 Presentation 一、动词-ing形式作主语

1. 动词-ing形式作主语表示抽象的或泛指的动作, 谓语动词用单数。如：

(Let students read aloud the sentences) (1)Playing tricks on others is impolite．

(2)Doing regular exercise can help build up your body．

(3)Talking is easier than doing. Complete the sentences according to the pictures. _______ _____ ______my favorite sport. _____ ___ ____ ___ is dangerous. ... 辨析：动词不定式和动名词都可以做主语。在意义上相近。动名词多用来表示泛指或抽象或习惯性动作；不定式多用来表示特指或某次具体的动作。Eg.

_____ (Walking/To walk) is a good form of exercise for both young and old. _____(Cleaning/ To clean ) the classroom this afternoon is our task. 2.

ing短语后置,常出现在一些固定结构中,Eg There is no good/harm/use/ in doing sth. There is no sense/point in dong sth. sth. is worth doing 二、动词-ing 形式作宾语

1.vt.+ doing

某些词后既可加不定式又可加动名词，但意义截然不同,如：

go on to do (做完一件事后)接着做另一件事

go on doing 继续做（原来做的事）

... 3.

动名词表示被动意义:动词

need, require, want, deserve 表示“需要”时，其后跟动名词的主动形式或不定式的被动式作宾语。

即: need/want/require+ doing
