2、专题详解。
一.学习目标:
1. 了解非谓语动词的基本特征。
2. 了解非谓语动词的种类和用法。
3. 了解非谓语动词一些特殊形式。
二.学习内容解析:
非谓语动词即在句子中不能作谓语动词,没有任何时态和人称方面的变化。
非谓语动词包括动词不定式(to do sth.),动名词(v-ing)以及分词(现在分词doing和过去分词done)分词初中阶段不要求掌握。
动词不定式(to do)的用法:
1. 作主语:
to learn english well is important.
to eat vegetables can help us keep healthy.
动词不定式作主语时,可以用动名词替换。
learning english is important.
eating vegetables can help us keep healthy.
动词不定式作主语时,常用it作形式主语,而把不定式放在后面。
it’s important to learn english.
it can help us keep healthy to eat vegetables.
2. 作表语:
my job is to teach english.
his hobby is to collect stamps.
3. 作宾语:
1).动词不定式常用作及物动词的宾语,这些动词有:want, begin/start, like/love, forget/remember, learn/teach, decide, hope, agree, plan, expect, manage, fail, offer, promise, refuse, pretend等。
he wants to go home at once. i began to play the piano when i was four.
2).动词不定式还可用作双宾的形式,这些动词有。
ask / tell / warn / wish / expect / order / force / encourage / allow / invite / wish / would like sb. to sth.
lucy asked him to turn down the radio. mother told me not to come home late.
i’d like you to meet my family.
4. 作定语: i h**e much work to do. do you h**e anything to say?
would you like sth. to eat? it’s a good place to h**e fun.
这种不定式与它所修饰的名词有逻辑上的动宾关系。如果这个不定式是不及物动词,它后面就。
要有必要的介词。
there is nothing to worry___
he has no room to live __
the dog is easy to take care of.
i’d like some ***** to write __
5. 作状语:
i came here to see you. (目的)
i’m sorry to hear that. (原因)
tom is too young to go to school. (结果)
to get to work, he takes no.7 bus every day. (目的)
使役动词make, let, h**e后的宾语补足语,其不定式的to要省略。而help 后的不定式可以带to,也可以不带to。但是改成被动语态时,要加“to”。
could you please help me (to) do some housework?
i hear him sing every night. (变成被动语态)
→he is heard to sing by me every night.(变成被动语态)
we saw her play the piano last night.
→she was seen to play the piano by us last night.
it made me feel sad.(变成被动语态)
→i was made to feel sad by it.
注意:感官动词see, hear, watch, notice等动词的用法:
seesb. hear sb. /sth. doing sth.
watchdo
notice
6. “疑问词+不定式”结构:
疑问词who, what, when, where, how, which等后接不定式,构成不定式短语,在句中作主语,宾语,表语等。
where to live is a problem. (主语)
do you know when to start? (宾语)
the problem is how to use the machine. (表语)
i don’t know to do it. (宾语)
a. whatb. how
动名词(v-ing)的用法:
1. 作主语:
2. 作表语:her f**orite is reading.
3. 作宾语:
4. 作定语:it’s a reading room.
running star, living room, eating habit, english-speaking country, tree-planting day
5. 有些动词后只能跟动名词而不能跟不定式,这些动词有:
enjoystop sb. from doing sth. (阻止某人做某事)
feel like doing sth. 想要做某事succeed in doing sth.
spend…(in) doing 花费……做某事 ⑥thanks for doing sth. 因某事感谢某人。
