三、不定式作宾补应注意的事项
能跟不定式作宾补的动词很多，如：
see, have, advise, expect, get,invite, consider, find, prefer,
feel, ask, for, call on, wait for…等等。大部分的动词或成语动词
之后跟带to的不定式作宾补，但也有一些动词之后要求跟不带to的不定式作宾补。下面谈一些要求跟不带to的不定式作宾补的动词。
1.这类动词有表示视觉、听觉和感觉的动词，如，
see, watch, notice, observe, look at, hear, listen to, feel
等。
（1） Did you see him steal the money?
（2） I haven’t noticed anyone go out.
（3）I’d like to look at （=watch） other people play basketb
all.
（4） I often hear her sing this song.
（5） She listened to someone call for help.
（6） Mary felt something crawl up her neck.
2.一些表示役使意义的动词，如have, make, let等。
（1） I would have Li Ming do the work.
（2） Her wonderful performance made all of us laugh.
（3）I’ll let someone find me a house to live in.
3.有时动词help的宾补既可以是带to的不定式亦可省略to,如，
I enjoy helping my mother （to） do housework.
4.上面所说的这些不带to的不定式做宾补，如改为被动语态就要用带to的不定式作主语补足语（略）。
5.一些表示心理状态语的动词，
如: consider, think, believe, discover, judge, sup pose 等，其后的宾语补足语有“认为”、“判定”的意思，认为宾语是什么，有什么性质、特征或处于某种状态，这时宾补要用“to be …”这种形式，
“to be”亦可省略。如：
（1） He considered him （to be） innocent.
（2） We all thought John （to be） quite a foolish man.
（3） The judge judged her （to be） guilty.
6.regard, treat, recognize, look upon, think of, consider 等这些词有时跟as词组或介词词组作宾补，如：
（1） All the teachers regarded this as of great importance.
（2） I always look upon you as my best friend.
（3）Don’t take my good intentions for evil ones.
有时有多种形式，以consider为例：
I consider him to be an honest man.
I consider him as an honest man.
I consider him an honest man.
四、宾语补足语和先行宾语
1.在复合宾语中，如果宾语不是名词或带词，而是其它的形式，如不定式（a），-ing分词结构（b）或that分句，这时就要用先行宾语it 来表示，而后将这些宾语移置宾补之后，如：
（1） it代替不定式或不定式的复合结构
We think it our duty to serve people heart and soul.
Do you believe it possible for us to land on the Mars one day?
I don’
t consider it polite of you to play tricks on others.
动词不定式作宾语及双宾语结构解析 1. 我们经常需要表达“同意做某事” 或“决定做某事”等句子，这种一个句子连续出现两个动词的情况下，我们要用到动词不定式作宾语，即agree / decide to do sth.。初中阶段我们常见后接动词不定式作宾语的动词有：plan，decide，want, agree, try, wait, wish, hope等。例如： I want to talk to Tom. 我想和汤姆谈话。 2. 双宾语就是有些动词后面跟直接宾语和间接宾语。直接宾语指的是动词所涉及的物，间接宾语是指动词所涉及的人。例如: They gave him a watch. 他们给了他一块手表。 这里的him是间接宾语，a watch是直接宾语，间接宾语和直接宾语同时出现时叫双宾语。 英语中，有许多及物动词后面能跟双宾语，如：give, bring, lend, pass, send, show, leave, buy, tell, teach, sell, write, buy, sing等。例如： He teaches us English. 他教我们英语。 The old man told us a story yesterday. 那位老人昨天给我们讲了一个故事。 ★注意：“及物动词＋间接宾语＋直接宾语”的结构一般可以改写为“及物动词＋直接宾语＋for / to sb.”的结构。例如： She bought me some presents. =She bought some presents for me. 她给我买了一些礼物。 Please show me your new book. =Please show your new book to me. 请给我看看你的新书。 【跟踪练习】同义句改写，每空一词。 1. I hope I can get higher marks next time. I hope_______________ higher marks next time. 2. He makes a plan to do some sightseeing this summer holiday. He _____________________ do some sightseeing this summer holiday.

动词不定式何时不带to? 在英语中，常见的不定式是带to的不定式，但在某些情况下，要使用不带to的不定式。关于这类不带to的不定式，在使用时极易出错，因此，只有经常注意分析此类语言现象，才能达到正确理解的目的。现将不带to的不定式的几种情况列举如下： 一、在“动词＋宾语＋不定式”结构中，如果动词是表示感官意义的，如see，feel，hear，observe，notice，watch， listen to，look at等等，其后作宾语补足语的动词不定式结构不带to。例如： Did you see him go into the house？你看到他进入那座房子了吗？ She looked at（watched）other people play basketball．她在观看别人打篮球。 I didn't notice anyone enter the room．我没注意到有人进入那房间。 He listened to us talk．他听我们谈话。 二、在使役动词make，let，have等之后，作宾语补足语的不定式结构不带to。例如： John made her tell him everything．约翰叫她把一切事情都告诉他。 The soldier had him stand with his back to his father．士兵要他背对他父亲站着。 Let me do it．让我来做。 注意：当这类动词转换为被动语态时，后面不带to的动词不定式要转换为带to的动词不定式（但have一般不用于被动句）。但当句子的动词为let时，to仍可省略。例如： The boy was seen to go into the house．有人看到那男孩走进那座房子。 They were made to work day and night．他们被迫日夜干活。 The prisoners were let go．罪犯被释放了。 三、在help后面可以接带to或不带to的不定式。例如： Can I help（to）carry it for you？我可以帮你拿这个吗？ They helped（to）carry the boxes upstairs．他们帮忙把箱子搬上楼去。 四、当介词except，but后接不定式时，如果except，but前面含行为动词do或do的各种词形时，不定式一般不带 to。例如： There was nothing to do but wait till he came back．没有办法只好等他回来。 He will do anything except lend you money．他决不会借钱给你。 如果except，but前面没有do这一动词或do的各种词形时，不定式一般都带to。例如： There's no choice but to wait for the rain to stop．没有别的选择，只好等雨停下来。 五、在“Why．．．？”或“Why not．．．？”结构中，紧接其后的动词不定式总是不带to。例如：

2014年8月4日 17:10 有关to do不定式的，to do不定式什么时候可以省略to do；还有什么时候用被动形式，什么时候不用。 一、使役动词与to的省略 当不定式用于let, make, have等使役动词后作宾语补足语，不定式必须省略to。如：Let me have another cup of tea. 给我再来一杯茶。 She had him dig away the snow. 她让他把雪挖走。 They made him tell them everything. 他们强迫他把一切全告诉他们。 但是，当使役动词用于被动语态时，其后的不定式则必须要带to。如： 他被迫一天工作20小时。 误：He was made work twenty hours a day. 正：He was made to work twenty hours a day. 注意，表示使役意义的let和have很少用于被动语态。 另外注意，force, oblige等虽然也表示“使”，但它们后用作宾语补足语的不定式必 须带to。如： They forced her to sign the paper.他们强迫她在文件上签字。 The law obliged parents to send their children to school. 法律要求父母送子女上学。 二、感觉动词与to的省略 当不定式用于表示感觉的动词feel, hear, notice, observe, see, watch, look at, listen to等作宾语补足语时，不定式必须省略to。如： We all felt the house shake. 我们都感觉这房子在震动。 I heard him go down the stairs. 我听见他下楼了。 Did you notice her leave the house? 她离开屋子你注意到了吗? I watched her get into the car. 我看着她上了车。 但是，当feel后用作宾语补足语的不定式为to be时，则不能省略to。如： They all felt the plan to be unwise. 他们都认为这个计划不明智。 注意，当这些动词变为被动语态时，不定式前的to不能省略。如： They were heard to break a glass in the next door. 听见他们在隔壁打破了一个玻璃杯子。 另外，若用作宾语补足语的不定式为完成式，则通常应带 to。如： I noticed her to have come early. 我注意到她来得很早。 三、why (not) 与to的省略 在why (not)…?之后的不定式不能带to。如： Why argue with him? He’ll never change his mind. 为什么要跟他争论? 他永远不会改变 自己的看法。 Why not try going by boat for a change? 为什么不试着坐船去，这样也可以换换花样? Why not wait till the winter sales to buy a new coat? 为什么不等到冬季大贱卖时再买一件新外衣呢? 四、介词except / but与to的省略 当不定式用作介词except或except的宾语时，该不定式有时带 to，有时不带 to，情形比较复杂，大致原则是：其前有do，不定式不带 to；其前没有 do，不定式通常带to。如： He likes nothing except to watch TV. 除了看电视外，他什么都不喜欢。 It had no effect except to make him angry. 除惹他生气外，没产生任何效果。

不带to的动词不定式有哪些 不定式是英语动词的非限定形式之一，是英语中一种非常活跃的语言现象，不带to的不定式（bare infinitive）是我们学习、掌握和运用这一语法现象的难点。本文的目的就是要对不带to的不定式作一粗浅的探讨。首先要指出的是，不带to的不定式的使用实际上非常普遍，主要用在情态动词和助动词will，shall，would，should，can，could，may，might，must…以及在作为情态动词的need和dare之后。但因为这一点在学习英语的过程中极易掌握，故不在此赘述。除此以外，在下列情况下也要使用不带to的动词不定式。 1．在see，feel，hear，watch，observe，listen to，look at, notice等感官动词或短语以及let，have，make等表示祈使意义的动词后面；不定式作宾语补足语不能带to；help后面的不定式可以不带to，也可以保留to；know在一定的条件下，后面的不定式作宾语补足语时可以不带to。例如： I saw the man come out of the house． I heard her say that she was from Japan． We felt the house shake． They watched the sun sink into the sea． Did you notice him stop？ They did not observe Jim come in and go upstairs． She was listening to him climb the stairs． Look at the boy run！ I'll let you know as soon as I hear from her． I had him mend my watch． Electricity makes motors run． He helped me（to）plant trees． I have never known him sing so beautifully． 不带to的动词不定式跟在上述动词后面时，情况比较复杂，有以下几个问题须特别注意： （1）当上述句子变成被动语态时，原来作宾语补足语的不定式则相应地成为主语补足语。这时，不定式就一定要带to，以上述句子为例：
动词不定式归纳(含练 习及答案)
动词不定式归纳 定义：不定式的to和介词to需要被区分开，不定式的to后接动词原形，介词to后接名词、代词或动名词。 不定式作动词宾语 He decided to invite all of his classmates to attend the holiday at the beach. 不定式作宾语 He promised not to tell anyone about it. 如果宾语有自己的补语，则常用it作形式宾语，而把真正作宾语的不定式放在后面放在后面，常带有形式宾语的动词有：believe. Consider. Feel. Find. Know. Make . regard 例： we think it important to obey the laws. √ we think to obey the laws is important. × I know it impossible to finish so much homework in a day. 不定式作介词宾语 当介词but、except、besides前面有行为动词do及其各种形式时，介词后面的不定式可以省略to，否则不省略。 What do you like to do besides play football？ We have no choice but to wait. 个别介词可以用“疑问词+不定式”作宾语 The boy has him own idea of how to finish it. 不定式起形容词作用作定语 不定式作定语用来修饰名词或代词，置于它所修饰的词后，而且放在其他后置定语的后面。同时与它所修饰的名词或代词形成逻辑上的动宾关系或主谓关系。 He always has a lot of meetings to attend. 不定式to attend 和名词meetings 形成动宾关系 The next train to arrive was from Seattle. To arrive 和train形成主谓关系 Do you have anything interesting to read? 如果作定语用的不定式是不及物动词，就要加上介词，使被修饰的这个词成为这个介词的逻辑宾语。 He is looking for a room to live in. to live in a room. A room 是介词in的宾语。 Please pass me some paper to write on. 上述不定式后加介词时，一般不能省略介词，但当修饰place，time，way时，介词可以省略。 He has no money and no place to live (in). The time to arrive is 8 o’clock. (at) I think the best way to travel is on foot. 不定式作定语时，用主动语态表示被动含义的情形 一、在某些固定句型中, 动词不定式作定语, 用主动形式表被动意义。 1）have（give, show）sth. to do 在这种句型中的不定式与前边的名词有动宾关系, 又和句中另一名词或代词构成主谓关系。例如: I have a lot of things to do this afternoon. to do与things是动宾关系, 与I是主谓关系。否则, 在表示被动意义时, 仍需要被动式。试比较: Have you anything to do this afternoon? 今天下午你有事要做吗?（to do是由you发出的） Have you anything to be taken to your parents? 你有要带给你父母的东西吗? （谁带不得而知）再如: Please get me something to read. 请给我弄点读的材料。He'll show you the right path to take. 2）It（This, That）＋be＋a／an＋adj. ＋ n. ＋to do 在这种句型中, 不定式与前面的名词有动宾关系。动词不定式可改为动词不定式复合结构。例如: This is a difficult question to answer. 这是个难答的问题。question与to answer为动宾关系。to answer 可改为 for me to answer。 再如: It is an easy sentence to translate. 这个句子很容易翻译。
省略to的动词不定式用法归纳 一、使役动词与to的省略 当不定式用于let, make, have等使役动词后作宾语补足语，不定式必须省略to。如： Let me have another cup of tea.给我再来一杯茶。 She had him dig away the snow.她让他把雪挖走。 They made him tell them everything.他们强迫他把一切全告诉他们。 但是，当使役动词用于被动语态时，其后的不定式则必须要带to。如： 他被迫一天工作20小时。 误：He was made work twenty hours a day. 正：He was made to work twenty hours a day. 注意，表示使役意义的let和have很少用于被动语态。 另外注意，force, oblige等虽然也表示“使”，但它们后用作宾语补足语的不定式必须带to。如： They forced her to sign the paper.他们强迫她在文件上签字。 The law obliged parents to send their children to school.法律要求父母送子女上学。 考例： 1.The teacher forbade ________ our seats. https://www.doczj.com/doc/655656333.html, to leave https://www.doczj.com/doc/655656333.html, leaving C.to leave D.to leaving 2.Mary had her friend ________ the best one. A.choose B.chosen C.chose D.to choose 3.The girl was ma de _________ she didn’t love at all. A.marry a man B.to marry a man C.to marry with a man D.married with a man 二、感觉动词与to的省略 当不定式用于表示感觉的动词feel, hear, notice, observe, see, watch, look at, listen to等作宾语补足语时，不定式必须省略to。如： We all felt the house shake.我们都感觉这房子在震动。 I heard him go down the stairs.我听见他下楼了。 Did you notice her leave the house?她离开屋子你注意到了吗? I watched her get into the car.我看着她上了车。 但是，当feel后用作宾语补足语的不定式为to be时，则不能省略to。如：They all felt the plan to be unwise.他们都认为这个计划不明智。 注意，当这些动词变为被动语态时，不定式前的to不能省略。如： They were heard to break a glass in the next door.听见他们在隔壁打破了一个
动词不定式作宾语 ★动词不定式就是一种非谓语动词形式,其结构为“to+动词原形”,其中to不就是介词,而就是动词不定式的符号,称为小品词,动词不定式没有人称与数的变化。动词不定式与其后面的名词等构成动词不定式短语,在句子中可以作主语、表语、补足语、定语、状语等。今天我们重点学习后接动词不定式作宾语的常见动词。 1.动词+ 不定式 Want hope decide agree choose would like plan fail 上列动词只能用动词不定式作宾语 举例: The driver failed to see the other car in time、 司机没能及时瞧见另一辆车。 I happen to know the answer to your question、 我碰巧知道您那道问题的答案。 I decided to go to the countryside on vacation、 我决定去农村度假。 2.动词+疑问词+不定式 Know ask show teach think guess find out understand 上列动词或短语后可用疑问词加动词不定式短语结构 举例: Please teach me how to play the piano、 请教我怎么弹钢琴。 I must think what to do next、 我必须考虑下一步做什么。 3.动词+不定式∕动名词 Like love begin start 上列动词后既可以接动词不定式也可以接动名词形式,意义上差别不大 举例: I like singing, but I don’t like to sing now、 我喜欢唱歌,但就是我现在不想唱歌。 Stop forget remember try
不带to的不定式用法 动词不定式的基本形式是“to+动词原形”，它具有名词、形容词、副词的特征，因此在句子里用作主语、宾语、宾语补足语、主语补足语、定语、状语和表语。但在某些结构中，不定式又往往不带to，现将有关不定式不带to的用法大致综述如下： 1．用在感觉动词see，watch，notice，look at，hear，listen to，feel等后，作为宾语补足语，动词不定式不带to。如： We often heard them sing．我们常常听到他们唱歌。 I saw her walk into the headmaster's office．我看见她走进了校长办公室。 2．用在使役动词make，let，have等后，作为宾语补足语，动词不定式不带to。如： What makes you think I'm a farmer？你怎么认为我是一个农民？ Now let me hear you play．现在让我听你演奏。 I'll have my brother repair the radio for you．我要让我哥哥给你修理收音机。 注意：感觉动词see，hear，watch，notice，feel，look at，listen to和使役动词let，make，have等用于被动语态时，动词不定式作为主语补足语则要带to。如： She was heard to sing in the next room．有人听到她在隔壁房间里唱歌。 3．用在 had better，had best（最好）， would rather（宁愿）, may/might as well (最好), cannot but (不得不, 必然, 不能不), can not help but (不得不) , can not choose but (不得不,只好), 等结构后，词不定式不带to。如： I'd better go and look for him．我最好现在就去找他。 You'd best get there before lunch．你最好午饭前到达那儿。 We would rather wait till tomorrow．我们宁愿等到明天。 4．两个或两个以上句法功能相同的动词不定式并列使用时，通常只是第一个动词不定式带to，后面的动词不定式则不带to。如： So he decided to go and get some medicine for his cough．因此他决定去买点咳嗽药。 They began to read and write．他们开始读和写。
句子成分 句子主要有以下几种成分： 1）主语（subject）是一句话的中心，整句话都在谈它的情况：my sister is a nurse. Her room is on the 5th floor. 2）谓语（predict）是主语的主要情况，可以表示动作，也可以表示状态：she works in a hotel.(动作) she knows a little English.（状态） 3）宾语（object）表示动作的承受者，也可以表示动作的结果：Everybody likes her. She is writing a letter now. 4）表语（predicative）和系动词一道构成谓语：she is conscientious girl.她是一个工作认真的女孩。 5）定语（attributive）修饰名词，代词等： Her hospital is not very big. But everyone in the hospital works hard.. 6）状语（adverbial）修饰动词，形容词或者副词：She goes to work very early. She feels very happy 此外还有同位语（appositive）插入语（parenthesis）以及呼语（vocative）This is my sister Mary. Mary is good girl, they say Sit down, Mary 句子的类型 1）按照说话的目的分为四类： A．陈述句（statement）: 陈述一个事实，表示一个看法等：Beijing is the capital of China She may be right. B．问句（question）: 提出问题： Where are you from? C．祈使句（imperative）提出命令请求等。 Don’t be late again. Take a seat, please. D．感叹句（exclamation）表示赞美惊异等情绪： W hat a nice view from the window! 2）从结构上来区分又可以分为三类： a简单句 如果一个句子只包含一个主谓结构，而句子各个成分都只用单词或短语表示,它就是简单句。 I live in the country. The teachers and students cheered at the news. 简单句主要由五种基本句型构成，千千万万的句子变化可以看作是这五种基本句型的扩展、省略、组合和倒装。 基本句型一：主语+谓语（不及物） The baby smiled. The teacher came in, followed by some students. 基本句型二：主语+谓语（系）+表语。
