教学目标：使学生学会使用-ing形式，尤其是作为主语、宾语。

教学重点：使学生能够判断-ing形式在句子中所作的成分。

所需教具：多媒体

ⅠExplanation -ing形式：包括现在分词(表语/定语/补语/状语)和动名词(主语/宾语/表语/定语)形式。

判断下列句子中的-ing形式是现在分词还是动名词。

Since then, finding ways to grow more rice has been his life goal. As a young man, he saw the great need for increasing the rice output.

He enjoys listening to violin music, playing mahjong, swimming and reading.

Our greatest happiness is serving the people.

His words are encouraging.

They set up an operating table in a small temple.

China is a developing country.

The student doing the experiment is our monitor.

I saw him going upstairs.

Using his hybrid rice, farmers are producing harvest twice as large as before. 说明：

1. 动名词和现在分词作定语时的区别

(1) 动名词作定语：表示被修饰词的用途

现在分词作定语：表示主动/进行

eg: They set up an operating table in a small temple.

China is a developing country. (2) 动名词作定语时只能是单个词；

现在分词作定语时可以是单个词，也可以是短语。

eg: The student doing the experiment is our monitor. 2. 动名词和现在分词作表语时的区别

动名词作表语时，主语和表语位置可以互换。

eg: Our greatest happiness is serving the people. * 现在分词作表语，一般指的是已经转化为形容词的分词形式。

比较：His words are encouraging.

He is doing his homework. 3. 动名词和现在分词的形式

动名词

doing sth / being done ；

having done sth / having been done

doing sth

( / done ) ；

being done；

having done sth / having been done 现在分词

译：The house being repaired

is Lily’s.

Being looked down upon made him angry.

4. 只能加动名词作宾语的动词

suggest / advise / forbid / allow / permit / admit / stand / appreciate / avoid / consider(考虑) / delay / excuse / risk / enjoy / escape(免于) / finish / imagine / keep (on) / mind / practice / miss / give up / feel like / can’t help(禁不住)/

be used to(习惯)/…

* 只接不定式作宾语的动词：afford / agree / decide / hope / determine / expect / manage / refuse / want(想要) / wish / offer / pretend / promise / choose / demand / fail /

intend / …

* 可接动名词/不定式作宾语的动词:

begin / start / continue / like / love / prefer / hate…；

forget / remember / regret / stop / try / mean / go on …

5. 动名词的逻辑主语一般用one’s （有时也可用名词/代词宾格) eg: I can’t imagine his being so rude.

6. 动名词的主动形式表被动。

①

Sth is worth doing. 某事值得(被)做。

②

Sth need/want/require doing. 某事需要(被)做。
