初二上学期学的哪些词后面+doing,哪些+to do,什么时候用过去式复数
初二上学期学的哪些词后面+doing,哪些+to do,什么时候用过去式复数
这个很复杂,我说的不一定全,反正常用的就是下面这些:
一、不定式的基本形式: to+动词原形,有时可以省略to.
二、 动词不定式的特点: (1)没有人称和数的变化,在句子中不能作谓语.
(2)动词不定式仍保留动词的特点,可以有自己的宾语和状语.动词不定式同它的宾语或状语可构成动词不定式短语.如: to read a book; to sing at the party.
(3)动词不定式具有名词、形容词和副词的特征,因此,在句中可以作主语、表语、宾语、宾语补足语、定语和状语.
三、动词不定式作宾语.即不定式直接跟在谓语动词后,是谓语动词涉及的直接对象.如果没有这个不定式,这个句子的意思就让人难以理解. 能直接带不定式作宾语的及物动词主要有: want, like , love , need , try , ask , learn , begin , start , forget , remember, hope , wish , agree, choose , fail , refuse , decide , afford , offer , make sure , take turns , would like , plan , hate , try one’s best 等.
四、动词不定式作宾语补足语. 能用动词不定式作宾语补足语的动词有: ask , tell , get , order , would like , want , teach , show , allow , encourage , warn , wish , invite ,help等.
五、动词不定式作状语: 即不定式直接跟在谓语动词后,仅对谓语动词起一个补充说明的作用.如果没有它,句子仍然意思完整,它不象作宾语那样,与谓语动词有着密切的关系.(1)表示目的: The doctor came to operate on her. He has gone to town to do some shopping. I sat down to have a rest. He stopped to have a look. He rushed into the room to save the girl. The moved away the stone to let the traffic go. He got up to catch the train.
(2)表示结果: The girl cried only to make her mother angry.
(3)表示程度: She is too tired to walk any farther. She is strong enough to carry the heavy box.
(4)表示原因: I was surprised to read the news.
能带不定式作状语的形容词有: glad , happy , pleased , angry , clever , careful , surprised , lucky ,ready ,sorry, amazed , afraid ,sad , unhappy , sure , free ,kind, nice , worried , easy , hard
六、不定式作定语: 动词不定式作定语,一般要放在被修饰词的后面,不定式与所修饰的词构成动宾关系. We have lots of work to do. Would you like something to drink? I want to get something to read during my holiday. That’s a difficult question to answer.
【注意】如果动词不定式是不及物动词,后面就应有必要的介词. 如: He is looking for a room to live in. Give me a piece of paper to write on. He has nothing to worry about. There is not enough space to stand in on the earth.. She is a nice person to work with. a place to go to.
七、动词不定式作主语: 如 To learn a foreign language is not easy.
在现代英语中,常用it来作形式主语,而把真正的动词不定式主语放在后面.即句型:
“It is+形容词+for ( of) sb. to do sth.”中,当形容词是kind ,nice , good , clever , careful , careless , right , wrong , foolish 等表示人的性格特征时, 用of ; 如果形容词为difficult , easy , hard, important ,interesting, possible ,necessary 等表示事物的特征时, 用for. It is necessary / important / easy / hard/ possible for us to learn English well. It is very kind /nice / good of you to help me with my English.
※ 在句型: 主语+find / think / feel / make +it +形容词+ to do sth.中,it为形式宾语.
I found it very important to learn English well. I think it easy to learn English well.
八、作表语: My job is to teach English. His wish is to become a scientist.
九、动词不定式和疑问词连用.动词不定式可以和疑问词what, which , how , when , where ,who 等连用,构成不定式短语,在句子中作主语、宾语、表语等成分.这时往往可以扩写成宾语从句; The question is how to use the computer.
I don’t know where to go for my holiday =I don’t know where I can go for my holiday.
He can’t decide which book to choose.= He can’t decide which book he can choose.
I don’t know what I should do next=I don’t know what to do next.
十、动词不定式的否定形式: not to+动词原形
Tell him not to be late. I will try not to read in bed.
十一、动词不定式省略to的场合:(1)作动词let, make , have, feel ,hear, see , watch , notice 等的宾语补足语时,动词不定式不带to. Let him do the work. He made me work day and night. I saw him fall off the bike.
(2)作动词help的宾语补足语时,动词不定式可带to,也可不带to.
He didn’t help me(to)mend the bike. You have helped ( to ) protect our environment.
(3)在助动词和一些情态动词如will , would , shall , should , can , could , may , might , must , do , does , did , didn’t , don’t , doesn’t 等的后面,用动词原形,即动词不定式不带to.
Will you help me? He doesn’t live here. It might rain . You must finish your homework on time.
(4)在why not…? , had better , would rather 等的后面也跟不带to的动词不定式.(原形)
Why not buy a dictionary? You had better (not)stay at home. I would rather go early.
(5)在第二个不定式前一般不带to. I would like to lie down and go to sleep.
Do you want to eat now or wait till later?
※ 在下列答语中, to不能省略: -Will you join me in a walk?-I will be glad to.
-Will you go swimming with me this afternoon?-I would love to.
-Used he work in the factory?-Yes , he used to .

一、 习惯上只接动名词作宾语的动词
admit(承认),advise(建议),allow(允许),anticipate(预料),appreciate(感激),avoid(避免),consider(考虑),defer(延期),delay(推迟),deny(否认),detest(讨厌),discuss(讨论),dislike(不喜欢),dread(担心),enjoy(喜爱),escape(逃脱),excuse(原谅),fancy(设想),finish(完成),forbid(禁止),forgive(原谅),imagine (想像),keep(保持),loathe(厌恶),mention(提及),mind(介意),miss(没赶上),pardon(原谅),permit(允许),practice(练习),prevent(阻止),prohibit(禁止),propose(建议),recollect(记得),report(报告),resent(愤恨),resist(抵制),risk(冒险),stand(容忍),stop(停止,阻止),suggest(提议),understand(理解)
二、接动名词或不定式作宾语且意义相差不大的动词
like(喜欢),love(喜欢),hate(憎恨),prefer(宁可),begin(开始),start(开始),continue(继续),can’t bear(不能忍受),bother(麻烦),intend(想要),cease(停止)
三、 接动名词或者不定式作宾语但意义不同的动词
接动名词或者不定式作宾语但意义不同的动词
1、remember(记得),forget(忘记),regret(后悔),stop(停止)
(1)后接不定式时指该不定式所表示的动作后发生.例如:
Remember to clean your room. 记得打扫房间.(还未打扫,先是remember,之后才clean)
He forgot to pay me the money. 他忘记要给我付钱了.(尚未付钱,forgot时还没pay)
He stopped to listen, but heard nothing. 他停下来听了听,但什么声音也没有听到.(先停后听)
(2)后接动名词时则指该动名词所表示的动作先发生.例如:
I remember cleaning the classroom. 我记得打扫了教室.(已打扫过)
He forgot paying me the money. 他忘记曾给我付过钱.(已付过钱了)
He stopped speaking. 他不讲话了.(先说后停)
(3)注意:go on to do sth 和go on doing sth 也有类似差别:前者表示做完某事后接着做另一事,后者表示继续做正在做的事.例如:
You shouldn’t go on living this way. 你不应该再这样生活下去了.(go on 后接doing通常被认为是现在分词而不是动名词)
Go on to do the other exercises after you have finished this one. 做完这个练习后, 请接着做其他的练习
2、try 后接不定式表示设法做某事,接动名词表示做某事试试(看有什么效果).例如:
I’ll try to come tomorrow. 我明天设法来.
Let’s try knocking at the back door. 咱们敲敲后门试试.
3、mean 后接不定式表示打算(想要)做某事,接动名词表示意味着(做某事,接动名词表示意味着要)做某事.例如:
He did not mean to hurt you. 他不是有意要伤害你.
This illness will mean going to hospital. 得了这种病就意味着要住院.
4、can’t help后接动名词表示禁不住做某事,接不定式表示不能帮助做某事.例如:
He couldn’t help crying when he heard the news. 他听到这个消息时禁不住哭了.
The medicine can’t help to get rid of your cold. 这药不能帮你治好感冒.
四、接“逻辑主语+动名词”结构的动词
接“逻辑主语+动名词”结构的动词
有些动词后接动名词作宾语时通常带有逻辑主语,构成“动词+名词/代词+动名词”或者“动词+物主形容词/名词所有格+动名词”的结构.此类动词通常有:dislike(或like的否定句),dread, fancy, mean, mind, involve, propose, recollect, remember, resent, save, stop, suggest, understand等.例如:
My father dislikes me/my working late. 我父亲不喜欢我工作到很晚.
He resented me/my being promoted before him. 他不满我先于他提升.
I don’t remember our teacher(’s) complaining. 我不记得老师曾抱怨过.
Do you mind his/him sitting here? 你介意他坐这儿吗?
excuse, forgive, pardon和prevent后除了可以用上述结构外,还可以接“代词+介词+动名词”的结构.例如:
Forgive my/me calling you up so early. 请原谅我这么早给你打电话.
Forgive me for calling you up so early. 请原谅我这么早给你打电话.
You can’t prevent his/him spending his own money. 你不能阻止他花他自己的钱.
You can’t prevent him from spending his own money. 你不能阻止他花他自己的钱.
五、 接不定式或者现在分词作宾补的动词
此类动词通常是see, hear, feel, smell, listen to, notice, watch等感官动词.我们一般用现在分词来表示正在进行的未完成的动作;用不定式表示已经完成的动作,经常性的动作,或非延续性的动作,此时的动词不定式在主动语态中不带to,在被动语态中必须带to.例如:
I saw him playing basketball on the playground. 我看见他在操场上打篮球.(正在打,部分过程)
I saw him play basketball on the playground. 我看见他在操场上打篮球.(打完球了,全过程;主动句,无to)
He was seen to play basketball on the playground. 有人看见他在操场上打篮球.(被动句,要带to)
I noticed him buy a pen in the shop. 我看见他在商店里买了一支笔.(buy为非延续性动词)
We often hear her sing in the classroom. 我们经常听见她在教室里唱歌.(经常性的动作)
what are you doing ? what is he doing ?
