否定形式：not doing …
* 归纳1：动名词作主语的用法 动名词作主语时，句子有两种形式：
① 动名词直接置于句首主语的位置上。
② 用形式主语it，把真正的主语——动名词结构移置句尾。但这种句子形式有一定的限制，作表语的只能是某些形容词或少数名词，如useful，useless，good，fun；no use，worth等。
Step II: Grammar learning.
A.Get the Ss to underline the sentences with v-ing form and then say out their function of v-ingforms.
A.I can’t avoid going．
