知 識(shí) 清 單
動(dòng) 詞 不 定 式
不定式:to + 動(dòng)詞原形
知識(shí)梳理:提綱挈領(lǐng),抓住重點(diǎn)和難點(diǎn)!
動(dòng)詞不定式的基本形式是“to + 動(dòng)詞原形”,有時(shí)可以不帶to。動(dòng)詞不定式(或不定式短語(yǔ))沒(méi)有人稱和數(shù)的變化,在句子中不能作謂語(yǔ)。動(dòng)詞不定式仍可保留動(dòng)詞的特點(diǎn),即可以有自己的賓語(yǔ)和狀語(yǔ)。動(dòng)詞不定式同它的賓語(yǔ)或狀語(yǔ)構(gòu)成不定式短語(yǔ)。如:to read the newspaper, to speak at the meeting 等
動(dòng)詞不定式具有名詞、形容詞和副詞的特征,因此在句子中可以作主語(yǔ)、表語(yǔ)、賓語(yǔ)、賓語(yǔ)補(bǔ)足語(yǔ)、定語(yǔ)和狀語(yǔ):
?句法作用
|
????????例 ??????句 ?
|
作賓語(yǔ)
|
She wanted to borrowed my radio.
They began?to read and write.
|
????作狀語(yǔ)
|
She went to see her grandma last Sunday .
He came to give us a talk yesterday.
|
作賓語(yǔ)補(bǔ)足語(yǔ)
|
Lucy asked him to turn off the radio.
She asked me?to speak more loudly
Jim told Ling Feng to go home at once .
The father made his son study hard.
|
??作定語(yǔ)
|
Have you got anything to say?
I had something?to eat this morning .
|
作主語(yǔ)
|
To learn a foreign language is not easy.
|
注:作主語(yǔ)用的動(dòng)詞不定式常常為it替代,動(dòng)詞不定式(或短語(yǔ))放在后面。例如:
??It is not easy to learn a foreign language.
??It?took us three days to do the work.
動(dòng)詞不定式的否定形式由“not+動(dòng)詞不定式”構(gòu)成. ?如:
Tell him not to be late.
The policeman told the boys not to play in the street.
4) 不定式省去to的情況: 在感官動(dòng)詞see,watch,look at,hear, listen to,feel和使役動(dòng)詞make,have,let等所接的賓語(yǔ)中(不定式做賓語(yǔ)不足語(yǔ)),不定式應(yīng)省去to。但是在被動(dòng)語(yǔ)態(tài)中不能省。如:
Let me listen to?you sing?the song.
He watched?his son?play?computer games.
I saw him?run?away.------He was seen?to run?away.
The boss?make the workers?work the whole night.----The workers were made?to work?the whole night.
5) 動(dòng)詞不定式和疑問(wèn)詞連用
?動(dòng)詞不定式可以和疑問(wèn)詞what ,which, how, where, when 等連用,構(gòu)成不定式短語(yǔ)。如:
??The question is when to start.
??I don’t know where to go .
??He showed me?how to use a computer.
??What to do?is a big problem.

二、動(dòng)名詞
1.動(dòng)名詞的構(gòu)成
動(dòng)名詞的基本形式為“v.+-ing”。
2.常跟動(dòng)名詞的詞
英語(yǔ)中有一些動(dòng)詞(短語(yǔ))后面常跟動(dòng)名詞作賓語(yǔ)。
收 我們初中階段常見(jiàn)的有:finish,enjoy,mind,miss,be worth , be busy , practice , have fun , have trouble / difficulty(in),feel like,be used to(習(xí)慣于),give up,keep on,consider,suggest,can't help。我們可按下面的順口溜記憶一些詞或短語(yǔ):
完成練習(xí)值得忙(finish,practice,be worth,be busy);繼續(xù)習(xí)慣別放棄(keep on,be used to,give up);
考慮建議不禁想(consider,suggest,can't help,feel like);
喜歡思念要介意(enjoy,miss,mind)。
3.注意含有介詞to的固定短語(yǔ)
在初中階段的英語(yǔ)學(xué)習(xí)中,學(xué)生常常會(huì)遇到含有介
詞的短語(yǔ),下列動(dòng)詞短語(yǔ)中的to為介詞,其后需要接名詞、代詞或動(dòng)名詞。
①make(a)contribution(s)to為……做貢獻(xiàn)。
②devote oneself to獻(xiàn)身,致力于……。如:
He has devoted himself to helping disabled people.
他一生致力于幫助殘疾人。
③look forward to期盼,盼望。如:
We are so much looking forward to seeing you again我們非常盼望再見(jiàn)到你。
④prefer...to...比起……更喜歡……。如
I prefer walking to cycling.我愿意步行,而不愿意騎自行車(chē)。
⑤be used to...習(xí)慣……;適應(yīng)……。如:
She is quite used to working hard.她很習(xí)慣努力工作。
4.兩組固定搭配
①prefer to do sth. rather than do sth. = prefer doing sth.to doing sth.寧愿做某件事而不愿做另一件事。如:
I prefer to learn English rather than play the piano on Sundays. =I prefer learning English to playing the piano on Sundays.在周日,我寧愿學(xué)習(xí)英語(yǔ),也不愿去彈鋼琴。
②need,require,want后跟不定式和動(dòng)名詞的區(qū)別
當(dāng)need,require,want作“需要”解時(shí),后加動(dòng)名詞等
于后加不定式的被動(dòng)式。如:
The window needs cleaning.
=The window needs to be cleaned.
那扇窗戶需要清洗。
三、分詞
1.分詞的構(gòu)成
分詞分為現(xiàn)在分詞和過(guò)去分詞兩種。現(xiàn)在分詞的本形式為“動(dòng)詞原形+-ing”;過(guò)去分詞的基本形式是“動(dòng)詞原形+-ed”,但也有不規(guī)則的形式。
2.現(xiàn)在分詞作賓補(bǔ)和不定式作賓補(bǔ)的區(qū)別
我們常見(jiàn)的動(dòng)詞如 see,watch,notice,hear等,接不帶to的不定式作賓補(bǔ),表示已經(jīng)完成了的或經(jīng)常性的動(dòng)作接現(xiàn)在分詞作賓補(bǔ),表示動(dòng)作正在進(jìn)行。如:
I heard him singing in the classroom.
我聽(tīng)到他正在教室里唱歌。(“唱”這個(gè)動(dòng)作正在進(jìn)行)
I heard him sing in the classroom.
我聽(tīng)到他在教室里唱歌了。(“唱”這個(gè)動(dòng)作已經(jīng)結(jié)
I saw him going up the stairs
我看見(jiàn)他正在上樓。(“上樓”這個(gè)動(dòng)作正在進(jìn)行)
I saw him go up the stairs.
我看見(jiàn)他上樓了。(“上樓”這個(gè)動(dòng)作已經(jīng)完成)
3.現(xiàn)在分詞和過(guò)去分詞的區(qū)別
(1)在語(yǔ)態(tài)上,現(xiàn)在分詞表示主動(dòng)意義,過(guò)去分詞表示被動(dòng)意義。如:
the exploiting class剝削階級(jí)
the exploited class 被剝削階級(jí)
(2)在時(shí)間上,現(xiàn)在分詞表示正在進(jìn)行的動(dòng)作,過(guò)去分詞表示已經(jīng)完成的動(dòng)作。如:
the developing country發(fā)展中國(guó)家
the developed country發(fā)達(dá)國(guó)家
the rising sun 正在升起的太陽(yáng)
the risen sun升起來(lái)的太陽(yáng)
4.have sb.do sth.,have sb./sth.doing sth.和have sth.done的區(qū)別
(1)have sb.do sth.意為“讓某人做某事”,have可以用let,make代替。不定式往往表示一次性的具體動(dòng)作,且強(qiáng)調(diào)動(dòng)作已經(jīng)完成或尚未發(fā)生。如:
The soldiers had the boy stand with his back to his father.
士兵們讓這個(gè)男孩背對(duì)他的父親站著
(2)have sb./sth.doing sth.意為“讓某人/物一直做某事”。have可以用keep代替,現(xiàn)在分詞(doing)所表示的動(dòng)作往往具有持續(xù)進(jìn)行的含義。如:
The two men had their lights burning all night long.
那兩個(gè)人讓燈通宵亮著。
(3)have sth.
sb.else to do sth.,過(guò)去分詞(done)所表示的動(dòng)作由他人(非主語(yǔ)本身)來(lái)完成,含有被動(dòng)意義。如
The driver had his car washed once a week.
這個(gè)司機(jī)一周讓人洗一次車(chē)。
