非谓语(非谓语)

来源:学生作业帮 编辑:作业帮 分类:英语作业 时间:2024/05/15 09:49:20
老师,我总是把非谓语做宾补和做定语混在一起,能告诉我如何明确的区分它们吗?还有判断非谓语是否做状语的关键是看它有没被逗号隔开吗?
解题思路: 非谓语
解题过程:
非谓语做宾补和做定语
非谓语动词(不能作谓语用)包括不定式、分词及动名词。
一、 动词不定式
1) 宾补:The teacher advised us to have a rest first.
I didnt notice them come in.
注:see, hear, watch, notice, have, make, let等动词后作宾补的动词不定式不带to, 但变为被动语态以后(即不定式作主补时)要带to, 其中let sb. do sth. 变为被动式为sb. is let do sth.
help(帮助)后作宾补的动词不定式可带to,也可不带to. 即help sb.(to)do sth.
2) 定语:不定式位于所修饰的名词,代词之后,如:Who was the first one to set
to the top of the hill yesterday? /He is the man to depend on/to believe in.

二、 分词
1.分词形式:有现在分词和过去分词两种。过去分词只有一种形式,现在分词则有:
一般主动式doing, 一般被动式being done, 完成主动式having done,完成被动式having been done
2.语法功能:在句中作定语、表语、宾补、状语。
3.现在分词和过去分词的区别:
1)语态不同:现在分词表示主动概念,及物动词的过去分词表示被动概念。例如:the moving film 动人的电影,the moved girl 受感动的姑娘,a running machine 一台转动的机器, a stolen car 一辆被盗的汽车
注:关于心理状态动词的-ing形式表主动意,-ed形式表被动意,详见该讲后的专题。
2)时间关系上不同:现在分词表正在进行的动作,过去分词往往表已经完成的动作。
例如:a developing country 发展中的国家,a developed country发达的国家
4.现在分词的基本用法:
1) 一般主动式用法:
A.作定语:The sleeping child is only five years old.(=The child who is sleeping is…)/The girl writing a letter there can speak English very well.(=The girl who is writing a letter can…)
The factory making TV sets is very large.(=The factory which makes TV sets is very large.)
C.作宾补:学用于see, watch, hear, feel, find, have, keep等动词之后。
例如:We can see steam rising from the wet clothes. /I saw Tom coming out of the house. /Dont keep the students doing homework all day.
注:上述动词后跟不定式作宾补表示动作的过程,而不是正在进行中的动作,而现在分词作宾补则表示正在进行中的动作。例如:I heard them singing in the room
when I passed it.(singing不可改为sing) Do you often hear them sing in the room ?(sing不可改为singing)
have sb. do sth. 与have sb. doing sth. 的区别:前者have=let, 后者have 有时表“keep”意,有时表“employ(雇用)”意。如:
Ill have him go with me.我将让他和我一块去。
Ill have him working in my compary.我将雇用他在我的公司里工作。
Dont have the machine working all day .不要让机器整天工作。
5.过去分词的基本用法:
1)过去分词作定语时的几种情况:
1. 前位修饰:单独一个过去分词作定语一般放在被修饰的名词之前。
We need more qualified teacher.我们需要更多合格的教师。
The wounded soldier lay on the ground, unable to move.那个伤员躺在地上,不能动弹。
2. 后位修饰:分词短语要置于被修饰的名词之后。
The girl dressed in red is my daughter. 穿红衣服的女孩是我女儿。
We are going to talk about the problem discussed at the last meeting.
我们准备谈一谈上次会上讨论的问题。
This is a letter written in blue ink.这是一封用蓝墨水写的信。
3. 后位修饰:如果被修饰的词是由some/ any/ no+ thing/ body/
one所成形的不定代词或指示代词those等时,虽然一个单一的分词作形容词时,也要放在被修饰词之后。
Is there anything unsolved?还有什么问题没有解决吗?
There is almost nothing changed since I left the town two years ago.
自从我两年前离开这个镇以来,几乎没有什么变化。
4. 有时为了强调还可将单一的分词置于被修饰名词之后。
They decided to change the material used.他们决定改变所用的原材料。
The experience gained will be of great value to us.取得的经验将对我们很有价值。
2)能够接过去分词作宾补的动词有以下三类:
1. 表示感觉或心理状态的动词。如:see, watch, observe, look at, hear, listen to, feel, notice,
think等。
1) I heard the song sung in English. 我听到有人用英语唱过这首歌。
2) He found his hometown greatly changed. 他发现他的家乡变化很大。
2. 表示“致使”意义的动词。如:have, make, get, keep, leave等。
3) I’ll have my hair cut tomorrow.明天我要理发。
4) He got his tooth pulled out yesterday. 他昨天把牙拔了。
5) Don’t leave those things undone.要把那些事情做完。
3. 表示“希望”、“要求”意义的动词。如:like, order, want, wish, expect等后用 “vt + ( to be )+pp”。
6) I would like this matter (to be) settled at once. 我希望此事立刻得到解决。
7) I wish my homework (to be)finished before five o’clock. 我希望5点前完成我的作业。
不定式to do 做状语
A.目的状语:She reads China Daily every day so as to improve her English.
注:in order to 可以位于句首或句中,so as to 不能位于句首。
B.原因状语: Im glad to see you . 注:这种“be+形容词+不定式”结构,其不定式有时也可视为宾语,如:He is eager to go to college./ She is sure to come here.
C.结果状语:They lived to see the liberation of their home town.他们一直活到见到家乡解放。
△在“too…to…”结构中表“太…结果不能”,如:He is too weak to do the work.
注:too之前如果有only, only too 表“非常”、“很”意,此时不定式不再表否定意,而表肯定意。如:They are only too lucky to go abroad for a visit. 他们很幸运去国外访问。
另外,too后如果是happy, glad之类形容词时,不定式也表肯定意,
如:She was too happy to meet her old friend in the street.
△在“形容词/副词+enough+不定式”结构中表“足以能…”,如:He is strong enough to do the work .
现在分词作状语的用法

①时间状语:Reading the letter, I couldnt help thinking of my school life.
②原因状语:Being ill, I didnt go to school yesterday.
③方式或伴随状语:Mary stood at the school gate waiting for Betty.
2)完成主动式用法:
这种分词所表示的动作发生在句中谓语动词所表示的动作之前,一般在句中作时间或原因状语用,不能作定语用。例如:
Having finished her homework,she went to bed. /Not having received his letter, she wrote to him again.

过去分词作状语的用法

过去分词作状语表示被动的和完成的动作。例如:

Written in a hurry, this article was not so good!

因为写得匆忙,这篇文章不是很好。

析: written 为过去分词作状语,表示这篇文章是被写的,而且已经被写。

值得注意的是,有些过去分词因来源于系表结构,作状语时不表被动而表主动。这样的过去分词及短语常见的有: lost (迷路); seated (坐); hidden (躲); stationed (驻扎); lost / absorbed in (沉溺于); born (出身于); dressed in (穿着); tired of (厌烦)。

Lost / Absorbed in deep thought, he didn't hear the sound. 因为沉溺于思考之中,所以他没听到那个声音。


过去分词作状语时其逻辑主语为主句的主语,此时应注意人称一致。例如:

Given another hour, I can also work out this problem.

再给我一个小时,我也能解这道题。

析: given 为过去分词作状语,它的逻辑主语为主句主语 I ,即 I 被再给一个小时。
