初中英语语法——非谓语动词
一、感知:谓语动词与非谓语动词的区别:
Tom likes playing chess.
My mother asked me to do homework
He will help me to do my homework.
We are visiting the museum built in the 18th century. (built作后置定语)
二、非谓语动词的定义:
1.不做谓语的动词
2.可做除谓语外的所有成分:主、宾、表、定、状、补足语。
3.构成:to do动词不定式/doing动名词/done过去分词
三、与谓语动词的区别:
谓语动词:有人称、时态、语气和数量的变化;非谓语动词:to do/doing/done
一句话中若已有谓语动词,且无 and/or/but 等并列连词、无从句引导词分隔,其余动词需改为非谓语形式。
e.g. My mother asked me to help with the housework.
四、动词不定式:to do/(to)do
1.定义:to只是符号,本身没有词义。具有名、形副词的特征,可做主、宾、表、宾补、定语和状语【表目的、将来】
2.结构:
肯定: to do/(to) do
My mother asked me to do homework.
否定: not to do/ not (to) do
My mother asked me not to do homework.
注意:区分两种否定:
陈述句的否定:是完全否定:
助动词don't/doesn't/didn't +do
My mother didn't ask me to do my homework
不定式的否定:是部分否定:
not to do(多用于宾补的情况)
My mother asked me not to play games.
3.功能:
(1)作主语:表示一种特定的、具体的动作或行为,多指未发生的动作,作主语时谓语要用单数形式
To talk with him is (be) a great pleasure.
注意:当to do过长时,用it作为形式主语
It is a great pleasure to talk with him.
it作形式主语的常见句型:
A. It’s+adj.+(for sb.)to do sth.做某事对某人来说...的(当adj.修饰to do结构时,介词用for,常见adj:important,necessary, essential, dangerous, hard, easy, impossible等)
B.It’s+adj.+of sb. to do sth. 某人是...的来做...(当adj.修饰sb.,介词用of,常见的adj.: kind, nice, friendly,good, right, wrong, clever, careful, careless, polite, foolish等)(补充:有些adj.如nice, right, wrong, good, wise等既可修饰sb也可修饰to do,介词选用for/of看情况而定)
It’s wise of them to turn down the suggestion.他们很明智,拒绝了这个建议。
It’s wise for them to turn down the suggestion.他们拒绝这个建议是明智的。
C.It’s+n.+to do 做...是...
D. It takes sb. time to do sth.花费某人...时间做某事
E. It's one's turn to do轮到某人做…
F. It seems to do似乎...
(2) 作宾语:放在谓语动词后的,v.+to do/v.+do
带to:v.+to do
口诀:想要决定努力学习,开始需要同意计划,希望不要拒绝帮忙
want to do/would like to do
decide to do
try to do
learn to do
start/begin to do
need to do
agree to do
plan to do
hope/wish to do
refuse to do
help (to) do
offer to do
......
不带to: V.+do
Why not do为什么不做?
had better do最好做
would rather do宁愿做
Can/Could/Would you please do...?你可以...吗?
注意:
1.在find/believe/consider/think等动词后,常用it作形式宾语:
we find to study English well(宾语) difficult(宾补).
We find it(形式宾语) difficult to study English well(真正宾语).
2.(难点)to do常与what/how/who/where/ when/which词连用构成宾从
I don't know how to do it./ I don’t know what to do.
(3) 作宾补:放在宾语后面,对宾语的状态进行补充说明的
带to:V.+sb.+to do
want to do
would like sb. to do
teach sb. to do
ask sb. to do
allow sb. to do
order sb. to do
tell sb. to do
advise sb. to do
encourage sb. to do
invite sb. to do
persuade sb. to do说服某人去做
expect sb. to do期待某人去做
cause sb. to do导致某人去做
不带to: v.+sb.+do
口诀:五看三使两听一感半帮助
五看:see/watch/look at/notice注意到/observe观察+ sb. do
补充:区分:
see:看到,强调看到内容/结果 see a bird/ a movie
watch:看,强调看会动的内容,watch TV/a film/a football match)
look:看见,强调动作,Look! look at sb./sth.
read:阅读,看书、报纸、杂志、文件等
三使:
let/make/have +sb. do使某人做,让某人做
(拓展)make 用于被动语态时,to 必须还原。主动:make sb. do被动:sb. be made to do
两听:
hear/listen to+ sb. do
一感:
feel+sb. do
半帮助:help +sb.(to)do
易混遗漏:使役动词have的两种区分:
have sb. do 让某人主动做;have sth. done 让某物被…
(4)作表语:放在系动词后,表目的、具体内容等,常常可以与主语互换
My job is to teach you English.→To teach you English is my job.
(5)作定语:起形容词作用,修饰名词、代词的,放在被修饰词的后面
The next train to arrive is from Beijing.
He was the first to come to the classroom.
(6) 作状语:起副词作用
目的状语
to do: To catch the bus, I got up early. I study hard to make my mother happy.
in order to do/so as to do为了做...

(7) 作独立成分:To begin with=To start with首先, to be honest=to be frank=honestly=to tell you the truth说实话,老实说
五、动名词:doing
1.定义:由动原+ing构成的,具有名词、动词特性,在句子中起到名词作用的,可作为主语、宾语、表语、定语四大成分的非谓语形式。
2.结构:
肯定:doing Would you mind me smoking?
否定:not doing Would you mind not smoking?
3.功能:
(1)作为主语:表示一种静态化的行为,类似于名词(to do结构倾向于“将要去做”,一般情况下to do和doing可互换),作为主语时,谓语动词用单数。
To swim is my plan.
Swimming is my plan.
注意:当主语过长时,可用it作为形式主语,常见句型:
1)It's no use/good/fun/worth+doing:做...是...的
2)It's useless/nice/worthwhile+doing:做...是无用的/好的/有价值的
3)It's a waste of time doing:做...是浪费时间的

(4)作定语:起形容词的作用,表用途、功能,放在被修饰词的前面:swimming pool, washing machine, reading room,drinking water可饮用的水,meeting room会议室....
(5)作为独立成分:Generally speaking通常来说,Frankly/Honestly speaking老实说,说实话
6、 分词
现在分词:doing表进行和主动
过去分词:done表完成和被动
1.定义:具有动词特性,具有形副词的功能,可帮助构成时态、语态,可做定、表、补、状语

e.g. His job is very interesting. He feels very excited.
(2)作定语:修饰名词、代词,单个分词放在被修饰词的前面,如果是分词短语放在后面
e.g. The woman sleeping on the sofa(后置定语) is my mother.
区分:现分:主语主动发出,表主语的状态;过分:被动承受 He is the boy called Tom.
(4) 作宾补:放在宾语的后面,有三种形式:动原,现分,过分
动原:V.+sb.+do(口诀:五看三使两听一感半帮助)
