一. 教学内容：
动词ing形式（动名词）的形式及用法
1. doing的形式：doing; being done
3. doing与to do在动词后面做宾语的区别
二. 知识总结归纳：
（一）动词ing形式起名词作用，在语法中也称做动名词．在句中做主语，宾语，表语和定语。它的基本形式有doing; being done。
例句：
1. Parking is difficult in the shopping center of the city.
2. My favorite job is teaching English.
3. His main hobby is collecting stamps.
4. Denying this will be shutting one’s eyes to fact.
5. I suggest you should practise speaking English whenever you can.
6. Hearing what I said, he couldn’t help laughing.
7. Did you see that car being repaired ?
注：to do形式也可以做主语或表语。一般情况下，这两种形式做主语或表语，差别不是很大。但是如果刻意强调某个具体的动作，就用to do 形式，而要表示一般性或泛指的动作则用doing形式。
例如：
1. It is difficult to park in the shopping center at the weekend.
2. My duty is to take care of the baby while she is out.
（二）在一些动词后面只能接动名词做宾语。后面跟doing 做宾语的常见动词有：admit; advise; appreciate; avoid; complete; consider; deny; mention; mind; miss; prevent; delay; enjoy; escape; imagine; postpone; practise; risk; suggest；常见的动名词短语，如：be worth doing; can’t help doing; look forward to doing; go on doing; insist on doing; prefer doing to doing; be busy doing; keep on doing; devote…to doing; spend…in doing; have difficulty in doing; have a good time doing; prevent…from doing

5. He insisted on sending for doctor at once.
6. The film is well worth seeing.
7. You can’t imagine the difficulty we had making a little money.
（三）doing形式的逻辑主语：当强调doing所表达的动作的执行者（逻辑主语）时，需要在doing前面加上物主代词，人称代词宾格，名词所有格或不定代词

1. I’m surprised at your/you doing it.

Don’t forget to do sth.=remember to do sth.
regret to do: 遗憾地去做/说regret
doing: 后悔做了某事
