用法（表、补、定、状）
一、动词不定式
动词不定时的构成：不定时的基本形式为：to+动词原形，有时可以不用to，这里的to 是不定式符号，本身无词义，动词不定式的否定形式是not+（to+）动词原形。

1.不定式作主语
动词不定式作主语时，常用it作形式主语，而将真正的主语放在句末
其结构为：It+be+adj.（+ for/ of sb.）+动词不定式
如：To learn English well is useful.→ It is useful to learn English well.
It’s important for us to protect the environment.
注意：在kind，good，nice，clever等表示人的品质的形容词后，不用for而用of。

如：It's very kind of you to help me. 你帮助我真是太好啦。

It's very clever of you to do like that.
2.不定式作宾语
有些谓语动词后只能用不定式作宾语，常见的这类词是表示命令、打算或希望的，如：would like, like, want, wish, hope, decide, plan, expect等。

如：Would you like to see a film this evening? 你今晚想去看电影吗？
②在find, think后跟不定式作宾语时，常用it代替，而将真正的宾语放在后面。

如：
I find it easy to read English every day.
3.不定式作宾语补足语
tell, ask, want, allow, warn, advise, invite, get, encourage后常跟动词不定式作宾语补足语。

如：Lucy asked him to turn down the radio.
My mother encourages me to learn Japanese. 我妈妈鼓励我学日语。

注意：还有一些使役动词和感官动词也用不定式作宾补，这时不定式要省略to。

这些动词有：一感（feel）、二听（hear, listen to）、三让（let, make, have）、四看（look at, see, watch, notice）。

但变被动语态时，必须加上to。

如：My friends were made to work the whole night by the boss. 老板让我的朋友们工作了一整夜。

4.不定式作定语
不定式作定语时，应放在名词之后。

它与名词有逻辑上的动宾关系。

注意：如果是不及物动词，且与所修饰的词之间有动宾关系，要在不定式后加上适当的介词。

There is nothing to worry about. 没有什么可担心的。

The room is big enough for 10 people to live in .
5.不定式常和疑问词what, which, when, where, how连用，相当于一个宾语从句。

如：
The teacher is telling the students what to do. 老师正告诉学生们做什么。

He didn't know where to go. 他不知道去哪里。

6.跟动词不定式的情况总结归纳：（加强记忆）

二、动名词
1、动名词的构成：动名词一般由“动词原形+ing”构成
2、V-ing做主语、谓语动词用单数形式
如：Eating too much is bad for your health. Seeing is believing.眼见为实。

4、跟动词的ing形式的情况总结归纳：（加强记忆）

avoid doing sth.避免做某事；consider doing sth.考虑做某事；
suggest doing sth.建议做某事；mind doing sth.介意做某事；keep doing sth.持续做
我们可按下面的顺口溜记忆这些词。

完成实践值得忙（finish, practice, be worth, be busy）
继续习惯别放弃（keep on, be used to, give up）
考虑建议不禁想（consider, suggest, can't help, feel like）
喜欢思念要介意（enjoy, miss, mind）

4.prefer doing sth to doing sth.（更喜欢）
5.devote...... to doing sth （致力于）
6. make a contribution to doing （做贡献）
三．分词包括现在分词和过去分词
1.现在分词做定语、其逻辑主语就是它所修饰的词；Do you know the girl standing there?
过去分词做定语、其逻辑宾语就是它所修饰的词Please hand in the written exercises.
<例>. The boy (cry)____ over there is my younger brother.
分析：依据cry与它的逻辑主语The boy之间的主动关系和cry的动作正在进行，所以用现在分词作定语修饰boy，因而正确答案为crying。

（单选）Time, ____ correctly, is money in the bank.
A. to use
B. used
C. using
D. Use
分析：因为本句已有谓语动词is，且没有连词或引导词，故排除谓语形式D；而time与use 为被动关系，所以选B。

谓语与非谓语动词过去分词作条件状语或时间状语表被动.
2.现在分词做表语表示主语的性质特征。

The situation is encouraging.
过去分词做表语表示某种状态。

The boy is too frightened to move.
3.现在分词做宾语补足语表示主动关系。

Don’t keep us waiting for a long time.
过去分词做宾语补足语表示被动关系。

He will have his hair cut after school.
4.分词做状语、逻辑主语是句子的主语。

The students went out of the room, talking and laughing.
Seen from the hill, our school looks more beautiful.
作状语:分词或分词短语可以作时间、原因、方式、结果、伴随等状语。

如：
Being a student, I must study hard.作为一名学生，我必须努力学习。

（原因状语）
He ran out of the room, shouting loudly.他大喊着从房间分阶段跑出来。

(伴随状语)
5现在分词表示正在进行的动作，过去分词表示完成的动作。

如：fallen leaves 落叶（已落下）falling leaves 正在飘落的树叶
developing country 发展中国家developed country 发达国家
6.现在分词表示事物本身所具有的性质，意为“令人……的”；过去分词表人感到.......
