不定代词概说：

英语的不定代词有all, each, both, either, neither, one, none, little, few, many, much, other, another, some, any, no, few, little, both, enough, every等，以及由some,any,no和every构成的合成代词（即somebody, anyone, nothing等）。在这些不定代词中，多数都能作主语、宾语、表语或定语，但是代词none以及由some, any, no和every构成的合成代词只能作主语、宾语或表语，不能作定语，而no和every则只用作定语。

不定代词用法对比：

1、so little与such little的区别：
用so little还是such little取决于little的意思：若表示数量方面的“少”，则用so little；若表示形状体积的“小”，则用such little： 
如：He has so little time for reading. 他读书的时间少得可怜。 
 I've never seen such little boxes. 我从未见过那样小的盒子。
2、some与any的用法区别：
一般说来，some用于肯定句中，any用于否定句和疑问句中。但是，在表示请求、邀请或征求意见的句子中，通常要用some而不用any：
如：Would you like some cake? 吃点蛋糕吗？
        Why not buy some bread? 为什么不买些面包呢？
        Shall I get some chalk for you? 要我帮你拿些粉笔来吗？
注：any有时也用于肯定句中，此时表示“任何”：
如：Any colour will do. 任何颜色都行。
        Come any day you like. 随便哪天来都可以。
3、many与much的用法区别：
两者都表示“许多”，但many修饰或代替可数名词(复数)，与few(少数)相对；
而much用来修饰或代替不可数名词（单数），与little（少量）相对。在口语中两者主要用于非肯定句中： 
如：Did you see many people there? 你在那儿看见许多人了吗?
        We don't have much time. 我们没有许多时间。
在肯定句中，一般用a lot of, lots of, plenty of 等代之。但在正式文体中有时也用于肯定句中；
另外，若用作主语或主语的定语，或其前有how, too, as, so, a good, a great等修饰，也可用于肯定句中：
如：Many of us left early. 我们有许多人离开得很早。
        Much work has been done. 许多工作都已经做了。
        You've given me too much. 你已给我太多了。
        Take as many(much) as you want. 你要多少拿多少。 
        I asked her a great many questions. 我问了她许多问题。
4、few, a few与little, a little的用法区别：
（1）few和a few后接可数名词的复数形式。few表示数量很少或几乎没有，强调“少”，含有否定意义；
a few表示数量虽然少但毕竟还有，强调“有”，含有肯定意义：
如：It is very difficult, and few people understand it. 它很难，没有几个人能懂。
        It is very difficult, but a few people understand it. 他虽难，但是有些人懂。
（2）little和alittle之后接不可数名词，其区别跟few和a few之间的区别相似：
如：Unfortunately, I had little money on me. 很不巧，我身上没带什么钱。
        Fortunately, I had a little money on me. 幸好我身上带着一点钱。
5、other, the other, another与others的用法区别：
这些不定代词不仅在含义上有单复数之分，而且在用法上有泛指（无the）和特指（有the）之别。其用法区别可归纳如下： 
（1）指单数时，若泛指用another，若特指用the other：
如：Give me another(one). 另外给我一个。 
        Shut the other eye, please. 请把另一只眼睛也闭上。
（2）指复数时，若泛指用other（后接复数名词），若特指用the other（后接复数名词）：
如：There are other ways of doing it. 做这事还有其他的办法。
       Where have the other students gone? 其他学生都到哪里去了？
（3）others永远表示复数意义（且其后不能再接名词）。其用法大致相当于“other+复数名词”，同样地the others大致相当于“the other＋复数名词”：
如：Other people[Others] may not think that way. 别的人可能不这样想。
        He is cleverer than the others[the other students] in her class. 他比班上其他学生聪明。
（4）another一般只能表单数，且其后接名词也只能接单数名词。但是若其后有数词或few修饰时，则也可接复数名词：
如：We need another few chairs. 我们还需要几把椅子。
        In another two weeks it'll be finished. 再过两个星期就可做完了。
（5）与some对比使用时，用others（此时与some同义）：
如：Some say yes, and others say no. 有人说对，有人说不对。

不定代词用法点拨：

1、指两者和三者的不定代词：
有些不定代词用于指两者(如both, either, neither)，有的不定代词用于指三者(如all, any, none, every)，注意不要弄混：
如：Both of my parents are doctors. 我的父母都是医生。
        All of the students are interested in it. 所有的学生对此都很感兴趣。
        There are trees on any side of the square. 广场的每一边都种有树。
        He has two sons, neither of whom is rich. 他有两个儿子，都不富有。
        He has three sons, none of whom is rich. 他有三个儿子，都不富有。
注：each可用于两者、三者或三者以上，而every只用于三者或三者以上，因此用于两者时只能用each，不能用every。

2、复合不定代词的用法特点：
复合不定代词包括something, somebody, someone, anything, anybody, anyone, nothing, nobody, noone, everything, everybody, everyone等。它们在句中可用作主语、宾语或表语，但不能用作定语。something, someone等和anything, anyone等的区别与some和any的区别一样，前者一般用于肯定句，后者一般用于否定句、疑问句或条件句。具体使用时应注意以下几点：
（1）复合不定代词受定语修饰时，定语应放在它们后面：
如：There is nothing wrong with the radio. 这收音机没有毛病。
        Have you seen anyone[anybody] famous? 你见过名人吗?
（2）指人的复合不定代词若用作主语，其谓语动词一般用单数，相应的人称代词和物主代词也用单数he, him, his(不一定指男性)。但在非正式文体中常用复数代词they, them, their：
如：Everyone knows this, doesn't he[don't they]? 人人都知道这一点，不是吗?
        If anybody[anyone] comes, ask him[them] to wait. 要是有人来，让他等着。
（3）指事物的复合不定代词若用作主语，谓语动词只能用单数，相应的人称代词也只能用it，而不用they：
如：Everything is ready, isn't it? 一切都准备好了，是吗?
（4）anyone, everyone等只能指人，不能指物，且其后一般不接of 短语。若是指物或后接of 短语，可用any one, every one(分开写)：
如：any one of the boys(books) 孩子们(书)当中的任何一个(本)
        every one of the students(schools) 每一个学生(一所学校)

3、是any not还是not any：
按英语习惯，any以及含有any的复合不定代词用于否定句时，它只能出现在否定词之后，而不能在否定词之前：
误：Anyone doesn't know how to do it.
正：No one knows how to do it.任何人都不知道如何做它。
误：Anybody[Anyone] can not do it.
正：Nobody[Noone] can do it.这事谁也干不了。
误：Anything can not prevent me from going.
正：Nothing can prevent me from going. 什么也不能阻挡我去。

4、不定代词与部分否定：
不定代词all, both, every等与not连用时构成部分否定；若要表示完全否定，则需换用none, neither, no one等。
比较：All of the students like the novel. 所有这些学生都喜欢这本小说。 
            Not all of the students like the novel. 并不是所有这些学生都喜欢这本小说。
            All of the students don't like the novel. 并不是所有这些学生都喜欢这本小说。
            None of the students like the novel. 这些学生当中没有一个喜欢这本小说。

5、all, both, each等用作同位语：
若用作主语同位语，主语可以是名词或代词；若用作宾语等其他成分的同位语，则宾语等成分必须是人称代词，而不能是名词：
如：We have all read it. 我们都读过他。(all修饰的主语是代词)
        The villages have all been destroyed. 村庄都被毁了。(all修饰的主语是名词)
        They told us all to wait there. 他叫我们都在那儿等。(all修饰的宾语是代词)
但不能说：They told the men all to wait there. (all修饰的宾语是名词不是代词)

不定代词知识体系：

不定代词与语境考题：

不定代词是高考的常考考点，有的不定代词考题出得比较灵活，不能死套规则，要注意结合语境来理解：
例1：—Is____here?
        —No, Bob and Tim have asked for leave.
A. anybody
B. everybody
C. somebody
D. nobody
解析：
若只是从表面来看，填空句是个疑问句，可能会误选A。但其实此题最佳答案应选B，因为下文的答句说“只有Bob和Tim请假了”，这说明问句是在查人数，故用Is everybody here? (大家都到齐了吗？)

例2：I agree with most of what you said, but I don't agree with_____.
A. everything
B. anything
C. something
D. nothing
解析：
此句若从表面看，有可能误选B，因为填空句为否定句。但实际上最佳答案为A，因为上文说“我同意他说的大部分内容”，这与下文的but I don't agree with everything (但并不是同意他说的所有内容)完全相符。

例3：—Doyouhave_____athomenow,Mary?
          —No, we still have to get some fruit and tea.
A. something
B. anything
C. everything
D. nothing
解析：答案：C，句意为“玛丽，现在家里东西都准备齐了吗？”“还没有，我们还要买些水果和茶。”

例4：—If you want a necklace, I'll buy one for you at once.
          —Oh, no. A necklace is not_____that I need most.
A. anything
B. something
C. nothing
D. everything
解析：
此题容易误选A，机械地认为：something用于肯定句，anything用于否定句或疑问句。但是，此题的最佳答案是B，something在此的意思不是“某种东西”，而是指“那种东西”或“这种东西”，即心中最想要的那种东西(相当于the thing)。

副词的概念：

副词是指在句子中表示行为或状态特征的词，用来修饰动词、形容词、其他副词、介词短语、非谓语动词乃至整个句子，表示时间、地点、程度、方式等概念。

副词的位置：

1）在动词之前。
2）在be动词、助动词之后。
3）多个助动词时，副词一般放在第一个助动词后。
注意：
a. 大多数方式副词位于句尾，但宾语过长，副词可以提前，以使句子平衡。
如：We could see very clearly a strange light ahead of us.
b. 方式副词well，badly糟、坏，hard等只放在句尾。
如：He speaks English well.

副词的排列顺序：

1）时间，地点副词，小单位的在前，大单位在后。
2）方式副词，短的在前，长的在后，并用and或but等连词连接。
如：Please write slowly and carefully.
3）多个不同副词排列：程度+地点+方式+时间副词。
注意：副词very可以修饰形容词，但不能修饰动词。
改错：（错）I very like English.
            （对）I like English very much.
注意：副词enough要放在形容词的后面，形容词enough放在名词前后都可。
如：I don't know him well enough. 
        There is enough food for everyone to eat.
        There is food enough for everyone to eat.

兼有两种形式的副词：

1）close与closely：
      close意思是“近”；closely意思是“仔细地”。
      如： He is sitting close to me.
               Watch him closely.
2）late与lately：
      late意思是"晚"；lately意思是“最近” 。
      如：You have come too late. 
              What have you been doing lately?
3）deep与deeply：
      deep意思是“深”，表示空间深度；deeply时常表示感情上的深度，“深深地” 。
      如：He pushed the stick deep into the mud. 
              Even father was deeply moved by the film.
4）high与highly：
      high表示空间高度；highly表示程度，相当于much。
      如：The plane was flying high.
              I think highly of your opinion.
5）wide与widely：
      wide表示空间宽度；widely意思是“广泛地”，“在许多地方”。
      如：He opened the door wide.
              English is widely used in the world.
6）free与freely：
      free的意思是“免费”；freely的意思是“无限制地”。
      如：You can eat free in my restaurant whenever you like. 
              You may speak freely, say what you like.

副词知识体系：

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：I saw her enter the bank. 我看见她进了银行。
误：He married with[to] a nurse.
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.

并列连词的概念：

连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。连词主要可分为两类：并列连词和从属连词。并列连词用来连接平行的词、词组和分句。如：and, but, or, nor, so, therefore, yet, however, for, hence, as well as, both...and, notonly...butalso, either...or, neither...nor, (and)then 等等。

并列连词与并列结构：

并列连词引导两个并列的句子。
1）and与or：
判断改错：
(错) They sat down and talk about something.
(错) They started to dance and sang.
(错) I saw two men sitting behind and whisper there.
(对) They sat down and talked about something.
(对) They started to dance and sing.
(对) I saw two men sitting behind and whispering there.
解析：第一句：and连接两个并列的谓语，所以talk应改为talked。
            第二句：and连接两个并列的动词不定式，第二个不定式往往省略to，因此sang应改为sing。
            第三句：and连接感观动词saw后面的用作的宾补的两个并列分词结构，因此whisper应改为whispering。
注意：and还可以和祈使句或名词词组连用表示条件。（or也有此用法）
如：Make up your mind, and you'll get the chance.=If you make up your mind, you'll get the chance.
        One more effort, and you'll succeed.=If you make one more effort, you'll succeed.
2）both...and 两者都
如：She plays(both) the piano and the guitar.
3）not only...but(also), as well as 不但…而且
如：She plays not only the piano, but(also) the guitar.
注意：not only…but also关联两个分句时，一个分句因有否定词not而必须倒装。
如：Not only does he like reading stories, but also he can even write some.
4）neither...nor 意思为“既不……也不……”谓语动词采用就近原则，与nor后的词保持一致。
如：Neither you nor he is to blame.

比较so和such ：

so与such的用法由不同词性决定。such是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副词。so还可与表示数量的形容词many，few，much，little连用，形成固定搭配。
构成：so+adj.
            such+a(n)+n.
            so+adj.+a(n)+n.
            such+n.(pl.)
            so+adj.+n.(pl.)
            such+n.(pl.)
            so+adj.+n.[不可数] 
            such+n.[不可数]
如：so foolish 
        such a fool  
        so nice a flower 
        such a nice flower 
        so many/few flowers 
        such nice flowers 
        so much/ little money.
        such rapid progress
        so many people
        such a lot of people
注：so many 已成固定搭配，a lot of 虽相当于many，但a lot of为名词性的，只能用such搭配。 so...that与such...that之间的转换既为so与such之间的转换。

并列连词用法点拨：

1、表示并列关系：
1）or意思为“否则”。
如：I must work hard, or I'll fail in the exam.
2）either...or意思为“或者……或者……”。注意谓语动词采用就近原则。
如：Either you or I am right.
2、表示转折或对比关系：
1）but表示转折，while表示对比。
如：Some people love cats, while others hate them.
典型例题：
—Would you like to come to dinner tonight?
—I'd like to, ___ I'm too busy.
    A. and
    B. so
    C. as
    D. but
答案：D。but与前面形成转折，符合语意。而表并列的and，结果的so，原因的as都不符合句意。
2）not...but...意思为“不是……而是……” not和but后面的用词要遵循一致原则。
如：They were not the bones of an animal, but(the bones) of a human being.
3、表示原因关系：
1）for 判断改错：
（错）For he is ill, he is absent today.
（对）He is absent today, for he is ill.  for是并列连词，不能置于含两个并列分句的句子的句首，只能将其放在两个分句中间。

并列连词知识体系：

比较and和or的用法：

1）并列结构中，or通常用于否定句，and用于肯定句。
2）但有时and也可用于否定句。请注意其不同特点：
如：There is no air or water in the moon.
        There is no air and no water on the moon.
在否定中并列结构用or连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。

典型例题：
—I don't like chicken___fish.
—I don't like chicken, ___I like fish very much.
A. and；and
B. and；but
C. or；but
D. or；and
答案：C。否定句中表并列用or,but表转折。
判断改错：
（错）We will die without air and water.
（错）We can't live without air or water.
（对）We will die without air or water.
（对）We can't live without air and water.

现在分词的概念：

现在分词（PresentParticiple）(又称-ing形式)，是分词的一种，是非限定动词，即在句子里面不能单独充当谓语，但能充当其它的一些成分（定语，表语，补语和状语）。一般式：doing；一般被动式：being done；完成式：having done；完成被动式：having been done。所有否定式都是在－ing前面加not。

现在分词的用法：

1）做表语：
如：He was very amusing.
        That book was rather boring.
很多动词的现在分词都可以作表语：exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.
2）作定语：
上面所出现的现在分词都可以用作定语,修饰一个名词：
如：That must have been a terrifying experience.
        I found him a charming person.
现在分词短语还可以放在名词的后面修饰名词,相当于一个定语从句：
如：There are a few boys swimming in the river.
        There is a car waiting outside.
3）作状语：
现在分词短语可以表示一个同时发生的次要的或伴随的动作：
如：Following Tom, we started to climb the mountain. 
        Opening the drawer, he took out a box.
        Taking a key out of his pocket, he opened the door.
现在分词短语还可以表示原因，相当于一个原因状语从句：
如：Not knowing her address, we couldn't get in touch with her.
        Being unemployed, he hasn't got much money.
现在分词短语还可以表示时间，相当于一个时间状语从句：
如：Hearing the news, they all jumped with joy.
        Returning home, he began to do his homework. 
        Jim hurt his arm while playing tennis.
        Be careful when crossing the road.
        Having found a hotel, we looked for some where to have dinner.
        Having finished her work, she went home.
4）作宾补：
现在分词在一些动词之后可以做宾语的补语：
例如：see, hear, catch, find, keep, have等。
如：I see him passing my house every day.
        I caught him stealing things in that shop.
        I smelt something burning.
        She kept him working all day.

现在分词其他用法解析：

1、现在分词一般式的用法：
现在分词的一般式所表示的动作与主语动作同时发生：
如：When we arrived, we found him sleeping. 我们到达时发现他在睡觉。
         Living in the 示的动作也可略早于或迟于谓语动作，但两者之间没有时间间隔：
如：Seeing nobody at home, he decided to leave a note. 发现没有在家，他决定留个字条。 
         He went home, finding the door locked. 他回到家，发现门是锁着的。当现在分词所表示的动作略迟于谓语动作时，现在分词通常位于句末。

2、现在分词完成式的用法：
现在分词的完成式主要表示发生在谓语动作之前的动作：
如：Having been there once, she knew the place quite well. 由于去过那儿一次，她对那地方很熟悉。
        Having failed twice, he didn't want to try again. 他已经失败了两次，不想再试了。
注：（1）现在分词的一般式和完成式均可表示已完成或先于谓语的动作，但有区别：现在分词所表示的动作虽然可以先于谓语动作，但两者之间没有时间间隔，而现在分词的完成式所表示先于谓语的动作则与谓语动作有一定的时间间隔：
如：Locking the door, he went out. 锁好门之后，他就出去了。
        Having invited him here to speak, we'd better go to his lecture. 既然我们请了他来作报告，我们最好去听一下。
有时即使是分词动作与谓语动作几乎同时发生，但如果要强调分词动作的完成性，也应用现在分词的完成式：
如：Having bought our tickets, we went into the theatre. 我们买好票后就走进剧场。
（2）现在分词的完成式一般不用作定语：
误：Do you know anyone having lost a cat? 你知道有谁丢了一只猫吗？
误：I want to talk to the person having broken the window. 我想同打破窗户的人谈谈。
若将以上现分词的完成式改为一般式也不可以（因为现在分词作后置定语时通常只表示与谓语动作同时或几乎同时发生的动作，而不能先于谓语动作而发生）：
误：I want to talk to the person breaking the window.

3、现在分词被动式的用法：
当要表示一个被动动作时，现在分词就用被动形式。现在分词的一般式和完成式均有被动式形式：
（1）现在分词一般式的被动式：主要表示现在正在进行的动作，也可表示与谓语动作同时发生的动作：
如：Who is the woman being operated on? 正在动手术的女人是谁?
         I saw him being taken away by the police. 我看见他被警察带走。
注：有时现在分词一般式的被动式所表示的动作也可发生在谓语动作之前（此时的现在分词通常用于表示原因，且多为状态动词）：
如：Not having a car, he finds it difficult to get around. 由于没车，她感到行动很困难。
（2）现在分词完成式的被动式：主要表示发生在谓语动词之前且已经完成的动作。
如：The subject having been opened, he had to go on with it. 话题已经开始了，他不得不谈下去。
        Having been written inhaste, the book has many mistakes. 这书因写得仓促，所以错误不少。
比较：Being so ill, she can't go to school. 由于病得那么严重，她不能去上学。
            Having been ill for a long time, he needed time to recover. 由于病了很长时间，他需要一段恢复的时间。

动名词概念：

动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语，也能被副词修饰，动名词有时态和语态的变化。

现在分词和动名词用法比较：

动词的-ing形式包括现在分词和动名词两种形式。他们的句法功能如下：
动词的-ing形式如果作句子的主语或者宾语时，应该是动名词形式；如果作补语或者状语时，应该是现在分词形式。那么作表语或者定语的动名词和现在分词又该怎样区分呢？
1、动名词与现在分词作表语时的比较：
（1）动名词作表语说明主语的内容，回答what的问题；现在分词作表语相当于形容词作表语，说明主语的性质、特征等，回答how的问题。
如：One of the best exercises is swimming. 游泳是最好的运动项目之一。 
        What pleases him most is bathing in the sea. 最使他高兴的事是在海中沐浴。 
        The situation both at home and abroad is very in-spiring. 国内外的形势都很鼓舞人心。
        The color is pleasing to the eye. 颜色悦目。
（2）动名词作表语，表语和主语几乎处于同等地位，可以互换位置，其句意不变；现在分词作表语，表语和主语则不能互换位置。
如：Our work is serving the people.
      （＝Serving the people is our work.）我们的工作是为人民服务。 
        The news was disappointing. 那消息令人失望。
（3）作表语的现在分词前可以用very，quite，rather，greatly等副词修饰，而动名词则不可以。
如：What he said was very encouraging. 他的话很鼓舞人心。
        Our goal is realizing the four modernizations in the near future. 我们的目标是在不久的将来实现四个现代化。
（4）现在分词与形容词一样可以和more，the most构成形容词的比较级和最高级，而动名词则不可以。
如：The story is the most fascinating. 那个故事最迷人。
（5）作表语用的现在分词除了和be连用以外，还可以和其它的系动词连用；而作表语的动名词则通常只能和be连用。
如：His speech seems inspiring．他的演讲似乎很鼓舞人心。
        His interest is writing for the news papers. 他的爱好是给报社写文章。
（6）有些用作表语的现在分词已经形容词化了。常见的有：exciting，moving，inspiring，missing，interesting，disappointing等。
2、动名词与现在分词作定语时的比较：
（1）动名词作定语时，表示它所修饰的名词的性能和用途，和它所修饰的名词在逻辑上没有主谓关系；
现在分词作定语时，表示它所修饰的名词正在进行的动作，和它所修饰的名词在逻辑上有主谓关系，常可以扩展成一个定语从句。
如：a swimming girl＝a girl who is swimming 一个在游泳的姑娘
        a walking stick＝a stick that is used for walking 一根拐杖
（2）现在分词作定语有时可以后置，而动名词则通常只能放在它所修饰的名词之前。
如：The girl wearing glasses is one of his students. 戴眼镜的那个女孩是他的一个学生。
        I bought some reading materials. 我买了一些阅读材料。

 动名词的用法：

1、作主语：
例如：Fighting broke out between the South and the North. 南方与北方开战了。　
2、作宾语：　　
a. 有些动词可以用动名词作宾语。
例如：admit承认 appreciate感激 avoid避免 complete完成 consider认为 delay耽误 deny否认 detest讨厌 endure忍受 enjoy喜欢 escape逃脱 fancy想象 finish完成 imagine想象 mind介意 miss想念 postpone推迟 practice训练 recall回忆 resent讨厌 resume继续 resist抵抗 risk冒险 suggest建议 face面对 include包括 stand忍受 understand理解 forgive宽恕 keep继续
例如：Would you mind turning down your radio a little, please? 你把收音机音量调小一点，好吗？
      　 The squirrel was lucky that it just missed being caught. 这松鼠幸运得很，刚逃避了被逮住的厄运。　　　　　
b. 有些结构后面可以用动名词作宾语或其他成分。
例如：admit to  prefer...to   burst out   keep on   insist on   count on   set about   put off   be good at   take up   give up   be successful in   be used to   lead to  devote oneself to   object to  stick to  no good   no use be fond of   look forward to  be proud of   be busy   can't help  be tired of   be capable of   be afraid of   think of
3、作表语，对主语说明、解释：
例如：Her job is washing, cleaning and taking care of the children. 她的工作是洗刷、清扫和照顾孩子。
比较：She is washing, cleaning and taking care of the children.
4、作定语，一般表示所修饰名词事物的用途：
例如：a writing desk=a desk for writing 写字台
            a swimming pool=a pool swimming 游泳池
有些动名词作定语，与所修饰的名词关系比较复杂。
例如：boiling point=a temperature point at which something begins to boil 沸点
            a walking tractor=a tractor which a driver can operate while he or she is walking behind it 手扶拖拉机

动名词知识体系：

动名词与不定式用法对比：

一般现在时的概念：

表示通常性、规律性、习惯性的状态或者动作（有时间规律发生的事件）的一种时间状态。

一般现在时的用法：

1）经常性或习惯性的动作，常与表示频度的时间状语连用。常用的时间状语有every...，sometimes，at...，on Sunday等。
例如：I leave home for school at 7 every morning. 每天早上我七点离开家。
2）客观真理，客观存在，科学事实。
例如：The earth moves around the sun. 地球绕太阳转动。　
            Shang hai lies in the east of China. 上海位于中国东部。
3）表示格言或警句。
例如：Pride goes before a fall.　骄者必败。　
注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。
例如：Columbus proved that the earth is round. 哥伦布证实了地球是圆的。
4）现在时刻的状态、能力、性格、个性。
例如：I don't want so much. 我不要那么多。　 
           Ann writes good English but does not speak well. 安英语写得不错，讲的可不行。
比较：Now I put the sugar in the cup. 把糖放入杯子。　　　
            I am doing my homework now. 我正在做功课。　　
第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。
第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。

一般现在时知识体系：

一般现在时用法拓展：

1、一般现在时表将来：
1）下列动词come, go, arrive, leave, start, begin, return的一般现在时可以表示将来，主要用来表示在时间上已确定或安排好的事情。
例如：The train leaves at six tomorrow morning. 火车明天上午六点开。　　　
       —When does the bus star? 汽车什么时候开
       —It stars in ten minutes. ？十分钟后。
2）以here, there 等开始的倒装句，表示动作正在进行。
例如：Here comes the bus.=The bus is coming. 车来了。　　　
            There goes the bell.=The bell is ringing. 铃响了。
3）在时间或条件句中。
例如：When Bill comes（不是will come）, ask him to wait for me. 比尔来后，让他等我。　　　
            I'll write to you as soon as I arrive there. 我到了那里，就写信给你。
4）在动词hope, take care that, make sure that 等的宾语从句中。
例如：I hope they have a nice time next week. 我希望他们下星期玩得开心。　　　
            Make sure that the windows are closed before you leave the room. 离开房间前，务必把窗户关了。
2、一般现在时代替一般将来时：
When, while, before, fter, till, once, as soon as, so long as, by the time, if, in case（that）, unless, even if, whether, the moment, the minute, the day, the year, immediately等引导的时间状语从句，条件句中，用一般现在时代替将来时。
例如：He is going to visit her aunt the day he arrives in Beijing. 他一到北京，就去看他姨妈。
3、一般现在时代替一般过去时：
1）"书上说"，"报纸上说"等。
例如：The news paper says that it's going to be cold tomorrow. 报纸上说明天会很冷的。　
2）叙述往事，使其生动。
例如：Napoleon's army now advances and the great battle begins. 拿破仑的军队正在向前挺进，大战开始了
4、一般现在时代替现在完成时：
1）有些动词用一般现在时代替完成时，如hear, tell, learn, write, understand, forget, know, find, say, remember等。
例如：I hear（=haveheard）he will go to London. 我听说了他将去伦敦。　
            I forget（=have forgotten）how old he is. 我忘了他多大了。
2）用句型"It is…since…"代替"It has been…since…"。
例如：It is（=has been）five years since we last met. 从我们上次见面以来，五年过去了。
5、一般现在时代替现在进行时：
在Here comes…/There goes…等句型里，用一般现在时代替现在进行时。
例如：There goes the bell.铃响了。

时态一致：
　
1、如果从句所叙述的为真理或相对不变的事实，则用现在时。
例如：At that time, people did not know that the earth moves. 那时，人们不知道地球是动的。　
            He told me last week that he is eighteen.上星期他告诉我他十八岁了。　
2、宾语从句中的，助动词ought, need, must, dare的时态是不变的。
例如：He thought that I need not tell you the truth. 他认为我不必告诉你真相。

状语从句的概念：

状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。

比较while/as/when：

1、as/when引导短暂性动作的动词例句：
如：Just as/Just when/When I stopped my car, a man came up to me.
2、当从句的动作发生于主句动作之前，只能用when引导这个从句，不可用as或while。
如：When you have finished your work, you may have a rest.
3、从句表示“随时间推移”连词能用as，不用when或while。
如：As the day went on, the weather got worse.

比较untill/till：

两个连词意义相同,肯定形式表示的意思是“做某事直至某时”，动词必须是延续性的。否定形式表达的意思是“直至某时才做某事”，动词为延续性或非延续性都可以。
正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
肯定句例句：I slept until midnight. 我一直睡到半夜时醒了。
                       Wait till I call you. 等着我叫你。
注意：在肯定句中可用before代替：Let's get in the wheat before the sunsets.
否定句例句：She didn't arrive until 6o'clock. 
                        I didn't manage to do it until you had explained how.
1、Until可用于句首，而till通常不用于句首。
例句：Until you told me, I had heard nothing of what happened.
2、Untilwhen疑问句中，until要放在句首。
例句：Until when are you staying? 你呆到什么时候？
注意：否定句可用另外两种句式表示。
1）Not until…在句首，主句用倒装。
例句：Not until the early years of the19th century did man know what heat is.
2）It is not until…that…

状语从句的用种类：

1、时间状语从句：
表示时间的状语从句可由when, as, while, whenever, after, before, till(until), since, once, as soon as(或the moment), by the time, no sooner…than, hardly(scarcely)… when, everytime等引导。 　　
e.g. When I came into the office, the teachers were having a meeting. 　　
       He started as soon as he received the news. 　　
       Once you see him, you will never forget him. 　　
       No sooner had I gone to bed than I went to sleep. 　　
2、原因状语从句：
原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as, nowthat（既然）等，for表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。 　　e.g. He is disappointed because he didn't get the position. 　　
      As it is raining, I will not go out. 　　
      Now that you mention it, I do remember. 　　
3、地点状语从句： 　　
引导地点状语从句的连词是where和wherever等。 　　
e.g. Sit wherever you like. 　　
      Make a mark where you have a question. 　　
4、目的状语从句： 　　
引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。 　　
e.g. Speak clearly, so that they may understand you. 　　
      She has bought the book in order that she could follow the TV lessons. 　　
      He left early in case he should miss the train. 　　
5、结果状语从句： 　　
结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that（从句谓语一般没有情态动词）,so…that, such…that等引导。 　　
e.g. She was ill, so that she didn't attend the meeting. 　　
      He was so excited that he could not say a word. 　　
      She is such a good teacher that everyone admires her. 　　
6、条件状语从句： 　　
条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。
引导条件状语从句的词（组）主要有if, unless, so(as)long as, on condition that, so(as) far as, if only(=if)。
注意：条件从句中的if不能用whether替换。 　　
e.g. If he is not in the office, he must be out for lunch. 　　
      You may borrow the book so long as you keep it clean. 　　
      So far as I know（据我所知）, he will be away for three months. 　　
      You can go swimming on condition that(=if) you don't go too far away from the river bank. 　　
      If he had come a few minutes earlier, he could have seen her. 　
7、让步状语从句： 　　
让步状语从句可由although, though, as, even if(though), however, whatever, whether…or, no matter who(when, what,…)等引导。
注意：as引导的让步状语从句一般是倒装的。 　　
e.g. Though he is a child, he knows a lot. 　　
      Child a she is, he knows a lot. 　　
      Whatever(=No matter what) you say, I'll never change my mind. 　　
8、方式状语从句： 　　
方式状语从句常由as, as if(though), the way, rather than等引导。 　　
e.g.You must do the exercise as I show you. 　　
      He acted as if nothing had happened. 　　
9、比较状语从句： 　　
比较状语从句常用than, so(as)…as, the more…the more等引导。 　　
e.g. I have made a lot more mistakes than you have. 　　
      He smokes cigarettes as expensive as he can afford. 　　
      The busier he is, the happier he feels.

使用状语从句时要注意的几个问题：　　

1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。　　
e.g. We'll go outing if it doesn't rain tomorrow. 　　
       I'll write to you as soon as I get to Shanghai. 　　
2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be，就可省略从句中的“主语+be”部分。　　
e.g. When(hewas) still a boy of ten, he had to work day and night. 　　
       If(you are) asked you may come in. 　　
       If(it is) necessary I'll explain to you again. 　　
3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。　　
e.g. You are to find it where you left it.（地点状语从句）　　
       Tell me the address where he lives.（定语从句，句中有先行词）　　
       I don't know where he came from.（宾语从句）　　
      Where he has gone is not known yet.（主语从句）　　
       This place is where they once hid.（表语从句）
注意：表示“一…就…”的结构 hardly/scarcely…when/before/no sooner…than和as soon as都可以表示“一…就…”的意思。
例句：I had hardly/scarcely got home when it began to rain.
            I had no sooner got home than it began to rain.
           As soon as I got home, it began to rain.
注意：如果hardly/scarcely或nosooner置于句首，句子必须用倒装结构：
例句：Hardly/Scarcely had I got home when it began to rain.
            No sooner had I got home than it began to rain.

主谓一致的概念：

谓语的数必须和主语的人称和数保持一致，这就叫主谓一致。

主谓一致的基本原则：

1)语法一致原则，即在语法形式上取得一致。例如，主语是单数形式，谓语动词也采取单数形式；主语是复数形式，谓语动词也采取复数形式。
例如：The students are very young.
            This picture looks beautiful.
2)意义一致原则，即从意义着眼处理一致关系。例如，主语形式虽是单数但意义是复数，谓语动词也采取复数形式；
而有些主语形式虽是复数但意义上看作单数，谓语动词也采取单数形式。
例如：The people in that country are fighting for independence.
            The crowd deeply respect their leader. 
            Three years in a strange land seems a long time.
3)就近原则，即谓语动词的单数或复数形式取决于最靠近它的词语。
例如：Neither hen or I am going to see the film tonight because we are busy.

几对容易混淆词组的一致用法：

1、由“this／thatkind／typeof+名词”作主语，谓语动词用单数形式；而由"these／thosekind／typeof+复数名词”作主语，谓语动词用复数形式。
例如：This kind of apples is highly priced.
            Those kind(s) of tests are good.
2、由“a number of，a totalo f，an average of+复数名词”作主语，谓语动词用复数形式；由“the number of，the total of，the average of+复数名词”作主语，谓语动词用单数形式。
例如：A number of students are waiting for the bus.
            The number of the students in this university is increasing yearly.
3、one of，the(only) one of的一致用法
例如：This is one of the books that have been recommended.
            This is the(only) one of the books that has been recommended.

 主谓一致用法点拨：

1、并列结构作主语谓语用复数：
如：Reading and writing are very important.
注意：当主语由and连结时，如果它表示一个单一的概念，即指同一人或同一物时，谓语动词用单数，and此时连接的两个词前只有一个冠词。
如：The iron and steel industry is very important to our life.
典型例题：
The League secretary and monitor___asked to make a speech at the meeting.
A. is
B. was
C. are
D. were
答案：B.
注：先从时态上考虑。这是过去发生的事情应用过去时，先排除A、C本题易误选D，因为The League secretary and monitor 好象是两个人，但仔细辨别，monitor前没有the，在英语中，当一人兼数职时只在第一个职务前加定冠词。后面的职务用and相连。这样本题主语为一个人，所以应选B。

2、主谓一致中的靠近原则：
1）当there be句型的主语是一系列事物时，谓语应与最邻近的主语保持一致。
例如：There is a pen, a knife and several books on the desk.
            There are twenty boy-students and twenty-three girl-students in the class.
2）当either…or…与neither…nor，连接两个主语时，谓语动词与最邻近的主语保持一致。
如果句子是由here, there引导，而主语又不止一个时，谓语通常也和最邻近的主语一致。
例如：Either you or she is to go. 
            Here is a pen, a few envelops and some paper for you.

3、谓语动词与前面的主语一致：
当主语后面跟有with, together with, like, except, but, no less than, as well as等词引起的短语时，谓语动词与前面的主语一致。
例如：The teacher together with some students is visiting the factory. 
            He as well as I wants to go boating.

4、谓语需用单数：
1）代词each和由every, some, no, any等构成的复合代词作主语，或主语中含有each,every,谓语需用单数。
例如：Each of us has a tape-recorder. 
2）当主语是一本书或一条格言时，谓语动词常用单数。
例如：The Arabian Night is a book known to lovers of English. 
3）表示金钱，时间，价格或度量衡的复合名词作主语时，通常把这些名词看作一个整体，谓语一般用单数。(用复数也可，意思不变。)
例如：Three weeks was allowed for making the necessary preparations.
            Ten yuan is enough.

5、指代意义决定谓语的单复数：
1）在代词what, which, who, none, some, any, more, most, all等词的单复数由其指代的词的单复数决定。
例如：All is right. (一切顺利。)
            All are present. (所有人都到齐了。)
2）集体名词作主语时，谓语的数要根据主语的意思来决定。
例如：family, audience, crew, crowd, class, company, committee等词后用复数形式时，意为这个集体中的各个成员，用单数时表示该个集体。
例如：His family isn't very large. 他家不是一个大家庭。
            His family are music lovers. 他的家人都是音乐爱好者。
但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。
例如：Are there any police around?
3）有些名词，如variety, number, population, proportion, majority等有时看作单数，有时看作复数。
A number of+名词复数+复数动词。 The number of+名词复数+单数动词。
例如：A number of books have lent out.
            The majority of the students like English.

6、与后接名词或代词保持一致：
1）用half of, part of, most of, a portion of等词引起主语时，动词通常与of后面的名词，代词保持一致。
例如：Most of his money is spent on books.
            Most of the students are taking an active part in sports.
2）在一些短语，如many a或more than one所修饰的词作主语时，谓语动词多用单数形式。
但由more than…of作主语时，动词应与其后的名词或代词保持一致。
例如：Many a person has read the novel. 许多人都读过这本书。
            More than 60percent of the students are from the city. 百分之六十多的学生都来自这个城市

主谓一致知识体系：

主谓一致用法拓展：

1）当everyone，everybody，noone，nobody，anyone，anybody，someone，somebody，everything，anything，something，nothing等用作主语时，其相应的代词一般用单数形式。
例如：If anybody calls, tell him that I'm out.
            Something strange happened, didn't it? 
2）人称代词与名词的呼应：人称代词I(me)，he(him)，she(her)，it(it) 都是代替前面的单数名词，而they(them)，we(us)则是代替复数名词的，you既可以代表单数，也可以代表复数。但表示泛指的时候，用he或one来表示。
例如：If a young person enters a classical music field only for money, he is in the wrong profession. 
3）物主代词与名词的呼应：my，our，his，her，its，their要与代替的名词在数上一致。
例如：The welfare department，as well as the other social services，will have its budget cut.
4）反身代词与其所代成分间的呼应。
例如：Many primitive people believed that by eating ananimal they could get some of the good qualities of that animal for themselves.
5）指示代词与所代名词间的呼应：this和that指代单数名词或不可数名词，these和those指代复数名词(those还可以用作先行词，引导定语从句，表示“那些人”)。
例如：She invited all those who had been her former colleagues.
6）much和muchof后接不可数名词，而many和manyof后接可数名词的复数。
例如：There is not much coal left.
            A great many of the houses were knocked down by the earthquake.
7）表示量的词后面有的接可数名词，有的接不可数名词。
接可数名词的有：a number of，a rangeof，a series of十复数名词；
接不可数名词的有：a great deal of，an amount of十不可数名词；
既可接可数又可接不可数名词的有：a lot of，a variety of。
