Teaching aids: Board and chalk; PPT Teaching procedure: Grammar Explanation; TBLT Teaching procedure: Step one: Introduction 1. v-ing形式的构成: 是在动词末尾加-ing 形式构成,即v-ing。否定形式: not+ v-ing构成

如: do-doing, be-being, ask-asking, not doing etc. 2. v-ing形式不能单独作谓语, 没有人称和数的变化,但可以有自己的宾语和状语, 还有时态和语态的变化。

3. v-ing形式由动词加-ing变化而成, 它同时具有名词和动词的特征, 在句中可以作主语、宾语等。也可以称为动名词。

Step two : The functions of the v-ing form 指出-ing形式在下面句中的成分。

•

1.

表示经常的、习惯性的动作或状态, 谓语动词通常用单数。如：

1）Walking is a good form of exercise for both young and old.

2）Watching news on TV has become a routine for me.

3）Going to Hangzhou by train takes about 16 hours.

二. it作形式主语代替动名词

动名词短语作主语常用it作形式主语，把动名词短语放在句末。

eg:Going to bed early and getting up early is considered to be a good habit. eg:It is considered to be a good habit going to bed early and getting up early. it 作形式主语的几个习惯句型：

It is no use/no good/no fun doing…

做某事没好处/没用/没意思

It is useless/worthwhile/funny doing…

It is a waste of time doing…

三. 在there be no...结构中作主语, 这种结构的意思相当于“It is impossible to do… ”。
