介词和介词短语
不定式

介词和介词短语的概念：

介词是一种用来表示词与词、词与句之间的关系的虚词，在句中不能单独作句子成分。介词后面一般有名词、代词或相当于名词的其他词类，短语或从句作它的宾语。介词和它的宾语构成介词词组，在句中作状语，表语，补语或介词宾语。介词可以分为时间介词、地点介词、方式介词和其他介词。

误用介词的三种情况：

1、多用介词：
多用介词可能是受汉语意思的影响将及物动词误用作不及物动词，也可能是受相关结构的影响而用错：
误：We discussed about the plan.
正：We discussed the plan. 我们讨论了计划。
误：Did he mention about the accident?
正：Did he mention the accident? 他提到那次事故了吗?
误：I saw her enter into the bank.

正：He married a nurse. 他同一位护士结了婚。
误：How can contact with you?
正：How can contact you? 我怎么与你联系?
误：We should serve for the people heart and soul.
正：We should serve the people heart and soul. 我们应该全心全意地为人民服务。
误：Who controls over the factory? (但名词control可接over)
正：Who controls the factory? 谁管理这个工厂?
误：He has a great many of friends here. (比较a great number of)
正：He has a great many friends here. 他在这儿有很多朋友。

2、漏用介词：
漏用介词可能是受汉语意思的影响将不及物动词误用作及物动词，或是受相关结构的影响的影响而用错等：
误：This matter is difficult to deal. (deal with=处理)
正：This matter is difficult to deal with. 这事很难处理。
误：He is not a man to be depended.
正：He is not a man to be depended on. 他不是个可靠的人。
误：He took a cup of tea, and went on the story.
正：He took a cup of tea, and wentonwiththestory.他喝了一口茶，又接着讲故事。
误：My mother still regards me a child. (比较consider…as中的as可省略)
正：My mother still regards me as a child. 我母亲还把我当小孩看。
误：They insisted sending a car over to fetch us.
正：They insisted on sending a car over to fetch us.他们坚持要派车来接我们。
误：What he says is worth listening.
正：What he said is worth listening to.他的话值得一听。

3、错用介词：
错用介词的情况比较复杂，可能是因受汉语意思的而错，也可能是因弄不清搭配关系而错，可能是混淆用法而错，也可能是受相关结构的影响而错，可能是忽略语境而错，也可能是想当然的用错：
误：She called on his office yesterday. (call on+人，call at+地点)
正：She called at his office yesterday. 她昨天去了他办公室拜访。
误：He is engaged with a nurse.
正：He is engaged to a nurse.他与一位护士订了婚。
误：The sun rises from the east.
正：The sun rises in the east.太阳从东方升起。
误：Under his help, I finished it in time.
正：With his help, I finished it in time. 在他的帮助下，我及时做完了。
误：During he was in Japan, he visited many places.
正：During his stay in Japan, he visited many places.他在日本期间,参观过许多地方。
误：We are familiar to his character.
正：We are familiar with his character.我们了解他的性格。
误：Help yourself with the fruit.
正：Help yourself to the fruit.吃点水果吧。

介词的宾语：

1、名词或代词作介词宾语：
如：Are you interested in history? 你对历史感兴趣吗？
        Don't worry about it. 别为它担心。
注：若是人称代词用作介词宾语，要注意用宾格。
如：No one can sing like her. 没有人能像她那样唱歌。(不能用like she)
2、动名词作介词宾语：
如：He is good at telling stories. 他善于讲故事。
        In crossing the street he was run over. 他在穿过马路时被汽车撞倒。
3、过去分词作介词宾语：
如：We can't regard the matter as settled. 我们不能认为这事已经解决。
        I take it for granted you have read the book. 我以为你读过这本书。
注：过去分词用作介词宾语通常只见于某些固定结构中，如上面第1句涉及regard…as(认为…是)结构，第2句涉及take sth for granted(认为某事属实)。在其他情况下，介词后通常不直接跟过去分词作宾语，若语义上需要接过去分词(表被动)，可换用“being+过去分词”：
如：He went out without being seen by the others.他出去了，没有被其他人看见。
4、从句作介词宾语：
如：He was not satisfied with what she said. 他对她说的不满意。
        I'm worried about where he is. 我担心他上哪儿去了。
注：介词后通常不接that从句，遇此情况需考虑用其他结构：
误：He paid no attention to that she was poor.
正：He paid no attention to the fact that she was poor. 他根本不注意她很穷这一事实。
但有个别介词(如except)可接that从句。
比较：I know nothing about him except that he lives next door./I know nothing about him except for the fact that he lives next door. 我只知道他住在隔壁,其它的就不知道了。
5、不定式作介词宾语：
如：I had no choice but to wait. 除了等，我没有别的选择。
       He wanted nothing but to stay there. 他只想留在那儿。
       They did nothing but complain. 他们老是一个劲地抱怨。
       He never did anything but watch TV. 除了看电视，他从不干任何事。
注：(1)介词后接不定式的情形通常只见于but, except等极个别个词。该不定式有时带to，有时不带to，其区别是：若其前出现了动词do，其后的不定式通常不带to；
若其前没有出现动词do，则其后的不定式通常带to。
(2)介词后虽然通常不直接跟不定式作宾语，但却可接“连接代词(副词)+不定式”结构：
如：He gave me some advice on how to do it. 对于如何做这事他给我提了些建议。
6、形容词作介词宾语：
如：Her pronunciation is far from perfect. 她的语音远不是完美的。
        In short, we must be prepared. 总而言之，我们要有准备。
        Things have gone from bad to worse. 事情越来越糟。
注：(1)有些形容词用作介词宾语可视为其前省略了动名词being：
如：He regarded the situationas(being) serious. 他认为形势严重。
        His work is far from(being) satisfactory. 他的工作丝毫不令人满意。
(2)有些“介词+形容词”的结构已构成固定搭配：in full全部地，全面地，无省略地； in private私下地，秘密地； in particular特别地；in general一般地，通常地，概括地； in brief 简言之；in short总之，简言之； in vain徒然地，徒劳无益地；for fee免费地，无偿地； for certain肯定地，确切地；for sure肯定地，确切地； for short为了简短，简称；atl arge自由自在地，逍遥法外； by far…得多
7、副词作介词宾语：
如：I can't stay for long. 我不能久呆。
        It's too hot in here. 这里面太热了。
        I looked every where except there. 除了那儿，我到处都看过了。
8、数词作介词宾语：
如：The city has a population of four million. 这座城市有四百万人口。
        He was among the first to arrive. 他是第一批到的。
9、介词短语作介词宾语：
如：Choose a book from among these. 从这些书中选一本吧。
        I saw her from across the street. 我从街的对面望见了她。
注：通常可后接介词短语作宾语的介词是from, till, until, since, except, instead of等。
比较：I took it from the bed. 我从床那儿(或床上)拿的。
            I took it from under the bed. 我从床下拿的。
10、复合结构用作介词宾语：
如：She had no objection to Mary marrying him. 她不反对玛丽与他结婚。
        She came in with a book in her hand. 她手里拿着一本书走了进来。
        All the afternoon he worked with the door locked. 整个下午他都锁着门在房里工作。

介词短语的句法功能：
1、表语：
如：He was with a friend. 他和一个朋友在一起。
        Health is above wealth. 健康胜过财富。
        This knife is for cutting bread. 这把小刀是用于切面包的。
注：有些介词(如because of)引出的短语通常只用作状语，不用作表语：
误：His absence is because of the rain.
正：His absence is due to the rain. 他因雨未来。
但是，若主语是代词(不是名词)，becauseof引出的短语可用作表语：
如：It is because of hard work. 那是因为辛苦工作的原因。
2、状语：
如：Don't touch it with your hands. 别用手去摸它。
        Did you do this by design or by accident? 你这样做是有意的还是无意的？
3、定语：
如：This is his reply to your letter. 这是他给你的回信。
        This is the best way of doing it. 这是做此事最好的方法。
        My love for you is deeper than the sea. 我对你的爱比海深。
4、宾语补足语：
如：I found everythingin good condition. 我发现一切正常。
       Her illness kept her in bed for a week. 她因生病在床上躺了一星期。
注：用作宾语补足语的介词短语在相应的被动语态中则为主语补足语：
如：He was regarded as a hero. 他被看成是英雄。
5、宾语：
如：A man stepped out from behind the wall. 一个人从墙后走出来。
        He cannot spare anytime except on Sunday. 除星期日外，他抽不出时间。
6、主语：
如：Between6 and 7 suits me. 六点到七点对我比较适合。
        After the exams is the time to relax. 考试后是轻松一下的时间。
注：介词短语通常不用作主语，尽管有时也像上面这样用作主语，但通常可视为是在一定的上下文中有所省略：
如：—When are we going to have the next meeting? 我们下次什么时候见面？
        —On Tuesday may be convenient. 星期二可能比较方便。
此句中onTuesday虽用作主语，但可视为是其前省略了meeting一词：
即：Meeting during the vacation may be convenient.

动词不定式的概念：

动词不定式指由to加上动词原形（而且只能是动词原形）所构成的一种非限定性动词，但在有些情况下to可以省略。动词不定式在语法功能上可作主语、宾语、宾语补足语、
表语、定语和状语。

不定式的特殊句型对比：

1、不定式的特殊句型too…to…：
1）too…to　太…以至于…。
例如：He is too excited to speak. 他太激动了，说不出话来。　
        —Can I help you? 需要我帮忙吗?
        —Well, I'm afraid the box is too heavy for you to carryi t, but thank you all the same. 不用了。这箱子太重，恐怕你搬不动。谢谢。
2）如在too前有否定词，则整个句子用否定词表达肯定，too后那个词表达一种委婉含义，意为“不太”。
例如：It's never too late to mend. 改过不嫌晚。（谚语）　
3）当too前面有only, all, but时，意思是：非常…等于very。
例如：I'm only too pleased to be able to help you. 能帮助你我非常高兴。　
            He was but too eager to get home. 他非常想回家。
2、不定式的特殊句型so as to：
1）表示目的：它的否定式是so as not to do。
例如：Tom kept quiet about the accident so as not to lose his job. 汤姆对事故保持沉默是为了不丢掉他的工作。　　　
            Go in quietly so as not to wake the baby. 轻点进去，别惊醒了婴儿。
2）表示结果：
例如：Would you be so kind as to tell me the time? 劳驾，现在几点了。
3、不定式的特殊句型：Why not：
“Whynot+动词原形”表达向某人提出建议，翻译为：为什么不……?   干吗不……?
例如：Why not take a holiday?

不定式的用法：

1、不定式作补语：
1）有些有动词+宾语+不定式的结构。
例如：advise allow cause challenge command compel drive驱使
enable encourage forbid force impel induce instruct invite like/love order permit make let have want get warn persuade request send tell train urge 等。
例如：Father will not allow us to play on the street. 父亲不让我们在街上玩耍。　　　　　　
            The officer ordered his men to fire. 长官命令士兵开火。
注意：有些动词如make，have，get，want等可用不定式作做宾补，也可用分词作宾补。现在分词表达主动，也表达正在进行，过去分词表达被动。
2）有些有动词+宾语+不定式的结构，不定式的动词往往是be，不定式一般可以省去。
例如：consider find believe think declare（声称） appoint guess fancy（设想） guess judge imagine know 等。
例如：We believe him to be guilty. 我们相信他是有罪的。
            We know him to be a fool. 我们知道他是个笨蛋。（tobe不能省去）
典型例题：Charles Babbage is generally considered___the first computer.
                    A. to invent　
                    B. inventing　
                    C. to have invented　
                    D. having invented　
答案：C. 一般没有consider+宾语+be以外不定式的结构，也没有consider+宾语+doing的结构，排除A、B、D。consider用动词be以外的不定式作宾补时，一般要求用不定式的完成式，故选C。 3）有些动词可以跟there+to be的结构。例如：believe expect intend like love mean prefer want wish understand 等。
例如：We didn't expect there to be so many people there. 我们没料到会有那么多人在那里。
            You wouldn't want there to be another war. 你不至于想让另外一场战争发生吧。
2、不定式作主语：
不定式作主语，往往用it作形式主语，真正的主语不定式放至句子的后面。　
例如：It's so nice to hear your voice. 听到你的声音真高兴。
            It's necessary for you to lock the car when you do not use it. 不用车的时候，锁车是有必要的。　
            It's very kind of you to help us. 他帮助我们，他真好。　
            It seemed selfish of him not to give them anything. 他不给他们任何东西，这显得太自私了。
3、不定式作表语：
不定式可放在be动词后面，形成表语。
例如：My work is to clean the room every day. 我的工作是每天清扫房间。　　
            His dream is to be a doctor. 他的梦想是成为一名医生。
4、不定式作定语：
不定式做定语通常要放在被修饰的词后，往往表示未发生的动作。
例如：I have a lot of work to do.我有许多事要做。　　　
            There was nothing to bring home that morning. 那天早上（他回家时）两手空空。
5、不定式作状语：
1）目的状语：常用结构为to do,only to do（仅仅为了）, in order to do,so as to do,so（such）...asto…（如此…以便…）。
例如：He ran so fast as to catch the first bus. 他飞快地跑以便赶上第一班车。　　
            I come here only to say good-bye to you. 我来仅仅是向你告别。
2）作结果状语，可以表示没有预料到的或事与愿违的结果，不定式要放在句子后面。
例如：I awoke to find my truck gone. 我醒来发现箱子不见了。　　
            He searched the room only to find nothing. 他搜索了房间，没发现什么。
3）表原因：
例如：I'm glad to see you. 见到你很高兴。
            She wept to see the sight. 她一看到这情形就哭了。
4）表示理由和条件：
例如：He must be a fool to say so.
            You will do well to speak more carefully.
            You will do well to speak more carefully.

不定式知识体系：

不定式用法拓展：

1、用作介词的to：
to可以用作介词，也可用作不定式的标示。下面的to都用作介词：admit to object to beaccus to med to beused to stick to turn to开始 look forward to be devoted to pay attention to contribute to apologize to devote oneself to

2、省去to的动词不定式：
1）情态动词（除ought外）后。
2）使役动词let,have,make后，感官动词see, watch, lookat, notice, observe, hear, listento, smell, feel, find等后。
注意：被动语态中不能省去to。
例如：I saw him dance. 我看见他跳舞。=He was seen to dance. 　
           The boss made them work the whole night. 老板让他们整夜干活。 =They were made to work the whole night.
3）would rather，had better句型后：
4）Why…/why not…句型后：
5）help后可带to，也可不带to, help sb（to）do sth：
6）but和except后：
but前是实义动词do时，后面出现的不定式不带to。
比较：He wants to do nothing but go out. 他只想出去玩。　　
            He wants to believe anything but to take the medicine. 除了吃这药，他什么都信。
7）由and, or和than连接的两个不定式，第二个to可以省去：
8）通常在discover, imagine, suppose, think等词后作宾补时，可以省去to be。
例如：He is supposed（to be）nice. 他应该是个好人。

3、动词不定式的否定式在不定式标志to前加上not。
例如：Tell him not to shut the window。让他别关窗。　
            She pretended not to see me when I passed by. 我走过的时候，她假装没看见。
4、It's for sb. 和It's of sb. 这样的句子中，由于表语形容词性质的不同，导致了不定式逻辑主语标志用for或of的区别。
1）for sb. 句型中的形容词一般为表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult, interesting, impossible等：
例如：It's very hard for him to study two languages. 对他来说学两门外语是很难的。
2）of sb句型中的形容词一般为表示性格，品德，心智能力，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。
例如：It's very nice of you to help me. 你来帮助我，你真是太好了。用for还是用of的另一种辨别方法：用介词for或of后面的逻辑主语作句子的主语，用介词前边的形容词作表语，造个句子。如果通顺用of，不通则用for。
例如：You are nice.（通顺，所以应用of）。　　
            He is hard.（非所表达的意思，不通，因此用for。）
