动词
动词的概述:英语中用来表示动作或状态的词叫动词。
动词的分类
动词可分为实义动词(行为动词)、系动词、助动词和情态动词四大类。
一、实义动词
实义动词(notional verb):含有实际意义,可单独充当句子的谓语。表示主语的动作、状态和品质。实义动词分为及物动词(transitive verb)和不及物动词(intransitive verb)。
实义动词的分类与用法
1.及物动词
及物动词
及物动词本身意义不完整,后面必须接宾语,意思才完整。
常见及物动词
visit, ask, win, answer, beat, serve, marry, enter, discuss, attend(参加), reach, drop(落下,放弃), kill, raise等等。
注意
当主语是物时,及物动词sell, feel, taste, wash, read, write 等常用作不及物动词,表示被动的意思,用来说明主语的特征。
① The silk feels soft.这丝绸摸上去很柔软。
②The pen writes well.这支笔很好用。
③ This kind of shoes sells well.这种鞋很畅销。
2.不及物动词
不及物动词本身意义完整,后面不能接宾语,若要接宾语,要用介词作“桥梁”。
常见不及物动词
go(to),come(to),happen(to) swim,run,dance,talk (to),reply (to), return (to), point(to, at ) , knock (at, on ), wait (for ), listen ( to), look (at ), arrive (in , at ), get (to),fall (off ), die (of , from), rise (up ) 等。
使用不及物动词时需注意
①不及物动词没有被动形式。
如:happen,occur,rise,lie,die, remain 等
The palace caught fire three times in the last century, and little of the original building
______now.
A.Remains
B.is remained
C.is remaining
D.has been remained
答案:A
②主动表示被动的不及物动词。
动词+(well,poorly,easily,badly,smoothly),物作主语,表示主语本身的性质。
如:sell, wash, burn, cook, cut, drive, dress,play, last, open, write, start, run, read,operate, break, measure, weigh等。
如:
(1) Dry wood burns easily.
(2) The cloth washes well.
(3) The door locks tightly.
(4) The pen writes smoothly.
3.兼任及物动词和不及物动词的动词
有些动词既可作及物动词,也可作不及物动词,且有时词义相同,有时不同。
4.延续性动词与终止性动词(瞬间动词)
延续性动词
表示行为或过程能持久地继续下去或产生持久的影响。如:eat, listen, read, run, walk, work,write等。
终止性动词
表示行为或过程是短暂的或瞬间完成结束。
如:arrive; begin; break; bring; buy; catch;close; come; die; discover; fall; leave; open; put on; take off; sell; start; stop; return; go;jump等。
如何判断句子中的动词该使用延续性动词还是终止性动词
(1)延续性动词不能与表示短暂时间的“点时间”状语连用。但:come/begin/get+to+延续性动词可表示一瞬间的动作。(“点时间”指具体某一时间点;“段时间”指某一时间内.)
如:
①It rained at eight yesterday morning.(误)
It began to rain at eight yesterday morning.(正)
因为rain为延续性动词,而at eight表示“点时间”,前后矛盾。
②---When did you get to know Jack?
----Two years ago.(get to know表示一瞬间的动作,与“点时间”two years ago连用)
③---Then you've known each other for more than two years.
----That's right.(know表示延续的动作,与“段时间”for two years连用)
(2) 终止性动词可以用于when引导的时间状语从句中,但不可以用于while引导的时间状语从句中。when表示的时间是“点时间”(从句谓语动词用终止性动词),也可以是“段时间”(从句谓语动词用延续性动词)。而while表示的是一个较长的时间或过程,从句谓语动词一般只能用延续性动词。
①When we reached London, it was twelve o'clock.(reach为终止性动词;when不可用while替换.)
②Please look after my daughter while/when we are away.(be away为延续性动词短语)
(3) 终止性动词的完成时态,表示动作的完成并产生了影响与结果。但一般不能与表示延续的时间段短语“for...”或“since…”以及“How long..."连用,终止性动词否定式除外。
①He has joined the army.他已经参军了。
②He has been a member of the army for three years.他已经参军三年了。
=He has been in the army for three years.
③His dog died five days ago.
=His dog has been dead for five days.
=It is five days since his dog died.
=Five days has passed since his dog died.
④I bought the bike two months ago.
=I have had the bike for two months.
=It is two months since I bought the bike.
=Two months has passed since I bought the bike.
⑤I haven't left here for 3 years.(haven't left 是终止性动词否定式,可与“段时间”连用)
⑥I haven't heard from him for 3 weeks.(haven't heard是终止性动词否定式,可与“段时间”连用)
现在完成时中,终止性动词可转换成延续性动词与“段时间”连用:
borrow→ke
buy→have
become→be
put on→ wear
move to→live in
recognize→know
begin/start→be on
die→ be dead
finish→be over
return→be back
come here→be here
go there→be there
come back→be back
fall asleep→be asleep
leave→be away from
get to/arrive/reach→be(in)
go(get)out→be out
fall ill→be ill
open sth→keep sth open
get up→be up
catch a cold→have a cold
get to know→know
join→be in+组织机构/→be a member of+组织机构
如:
I have bought this bike.﹙√﹚
I have bought this bike for two years.﹙×﹚
I have had this bike for two years.﹙√﹚
= I bought this bike two years ago.
(4)"not+终止性动词+until/till..."意为“直到……才……”。“延续性动词+until/till..."表示:“...一直延续到....”
①I will not go to bed until I finish drawing the picture tonight.今天晚上直到我画完画,我才上床睡觉。
②I won't leave till my parents come back.(我将呆在家里直到我父母回来。言外之意是,我父母不回来,我就一直呆在家里,我父母回来后我就离开家。)
③I didn't receive the notice until last evening.(直到昨天晚上我才收到通知。言外之意是,昨天晚上前我一直没有接到通知。)
④We worked until 11:00 yesterday evening.(我们昨天晚上一直工作到11点。)
