不定代词讲解~详细 一、不定代词some 与any 的用法区别 一般说来，不定代词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： 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？ 【说明】不定代词any 有时也用于肯定句中，此时表示“任何”： Any colour will do. 任何颜色都行。Come any day you like. 随便哪天来都可以。 二、不定代词many 与much 的用法以及区别 不定代词many 和much 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： 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。 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。 辨析：too much；much too；too many 1、too much常用作副词或代词,也可以用作形容词修饰不可数名词.如： Is watching TV too much good or bad for your health?电视看得太多对你的健康有益还是有害? You've given me too much.你给我的太多了. We've had too much rain lately.最近我们这里的雨下得太多了. 2、much too常作副词,后接副词或形容词.如： He drove much too fast.他开车开得太快了. It is much too cold.天实在太冷了. 3、too many常用作形容词,修饰可数名词复数.如： They built too many buildings last year.去年他们建了许多楼房. 三、either、neither的用法以及区别 1、用作副词。either也（不），用于否定句中。 如：I don’t like fishing, David doesn’t like fishing, either.我不喜欢钓鱼，大卫也不喜欢。 neither也不；用于肯定句，表示否定含义。如：He can’t swim, and neither / nor can I. 他不会游泳，我也不会。 2、用作代词。范围多限定于两者之间，常用作主语。either of 和neither of +名词/代词的复数，作主语时，谓语动词用单数。 either表示“二者之一”；neither 表示“两者都不”，其反义词是both。 如：Either of the knives is useful．两把刀都有用。 Neither of them was in good health, but both worked very hard．他们两人身体都不好，但都努力地工作。 3、用作连词：either…or…不是……就是……neither…nor…既不……也不……常用来连接两个并列成分，如并列主语、并列谓语等。谓语动词保持就近原则，与离它最近的主语在人称和数上保持一致。 但应注意以下几点： 1．无论either…or…还是neither…nor…，若连接两个单数数名词/代词作主语，后面动词用单数。 Either Mary or Lucy is coming．不是玛丽来，就是露西来。 2．若连接两个复数名词/代词作主语，后面动词用复数。Neither my parents nor my grandparents are coming． 我的父母不来，我的爷爷奶奶也不来。 3．如果一个单数名词/代词和一个复数名词/代词一起作主语时，动词的单复数形式必须和最靠近的一个主语保持一致。（就近原则）

You should not be forgetful of your responsibilities. 人们不应该忽视自己的职责。 2. 用作替代词，可用于代替可数名词，但不能替代不可数名词，用法如下： (1) 使用时要注意分清是泛指还是特指： ①表泛指或非特指，直接用one，其前不用不定冠词。如： A fast train is one that goes fast. 快车是一种行驶快的火车。 This dictionary has several appendices, including one on irregular verbs. 这部词典有几项附录，包括不规则动词附录。 但是，若one的前面受到形容词的修饰，则其前必须要用不定冠词。如：

不定代词用法总结-标准化文件发布号：（9556-EUATWK-MWUB-WUNN-INNUL-DDQTY-KII
不定代词用法总结 1) some, any, no的用法 a. some和any通常用于表示不定数或不定量，修饰复数可数名词或不可数名词。some表示“几个；一些；部 分”，多用于肯定句；而any表示“一些；什么；任何；”，对用于否定句或疑问句中。如： * He asked me some questions. (他问了我几个问题。) * Some of the bread has been eaten. (面包已吃了一些。) * Are there any stamps in this post office (这个邮局里有邮票吗？) * I didn’t have any cigarettes, so I went out to buy some. (我没有香烟了，所以出去买了一些。) b. 刚才我们说some一般用于肯定句而any一般用于否定句和疑问句。但有时也有例外。这要根据句子意思来 看。 * I could not answer some of his questions. (我不能回答他的某些问题。) (some用在否定句中表示“一些；部分”。如果说成：I could not answer any of his questions.意思就变了，它表示“我不能回答他的任何问题。”) * Will you get me some apples on your way back (你回来的路上能给我带一些苹果吗？) (some用在疑问句中大多表示“请求” 或“建议”) * Let me know if you hear any news. (如果你有任何消息请告诉我。) (any用在条件从句中表示“任何”) * “What would you like to drink” “Any will do.” (“你想喝什么？”“哪种都行。”) (any在这里表示“任何”) c. no在句子中作定语，表示否定，意思是“没有；不是”，它可以修饰可数名词的单数和复数形式或不可数名 词。 * There are no letters for you today.

Can you hear them talking (你办公室里有人。你听见他们说话了吗？) d. 第二部分为-thing的复合代词只能用于指物。如： * There was something wrong with the car so he had to stopped it. * He looked at me and didn’t say anything. * Nothing can be done to save her life. e. 这些复合不定代词如果有其它的形容词修饰，形容词必须后置。如： * Somebody important has arrived, I’m sure. (important修饰somebody) 3) one和none的用法 不定代词one指代可数名词的单数，即指人，也指物。它的复数形式是ones。在句中可以作主语、宾语、定语等。 * He is not the one who is easily cheated. (one指人) * I’ve made some cakes. Would you like one of them (one指物) * I prefer red roses to white ones. (ones指物) * Are they the ones who moved here a few days ago (ones指人) 4) all, every, each, other, another, either, neither, both a. every只有形容词的性质，在句中作定语。常用于修饰单数的可数名词。表示“每个；各个”，还可以表示“一 切”。 * After the strong wind every flower in the garden was gone. every还可以和-one, -thing, -body构成复合不定代词，即：everyone, everything, everybody。其中，everyone和everybody用于指人，意思一样，都是“每人；大家”，形式上表示单数意思上可以表示单数也可以表示复数。everything用于指物，意思是“每件事；一切”，形式上表示单数意思上可以表示单数也可以表示复数。如：* One can’t have everything. * Everything goes well with me. * The town is so small that everybody knows everybody else. 注意：在使用everyone时要注意和every one相区别。everyone是一个不定代词而every on是一个词组，前者只能指人而后者既可以指人也可以指物。请注意下列例句： * Everyone will be here except Patrick. (everyone 指人) * Every one of the children will get a gift. (every one也指人) *We played several matches against the visitors, but unluckily lost every one. (every one指物)

One是泛指，但有限定修饰语，如the, this, that…修饰就变成了特指。如： ①One must do one's duty. ②Mary has a red pencil and Jane has a blue one. ③The new designs are much better than the old ones. 3）.that只指物，不指人，可替代可数名词或不可数名词，具有“特指”性质。指的是同类事物中的另一样东西，即同类异物。如：The library of our school is bigger than that of yours.(that 代替的是另一个图书馆。) 4）one 和that 在代替可数名词时，如果没有前置定语只有后置定语时，the one 和that 可互换。但该名词如有前置定语，则只能用the one,而不能用that。例如： ①I will take the seat next to the one(=that)by the window.我就坐窗口的那个座位旁边。 ②I prefer the large box to the small one.(one 不可用that替换)。 5）That的复数形式those代替可数名词的复数。可指人或物，一般后面跟修饰语。如： ①Today's cellphones are smaller than those(=the ones)used in the past. ②The students who do best in exam are not always those(=the ones) with the best brains. 6）the one(ones)或that ,those 指代某一名词做定语从句的先行词时，其关系代词which在that之后，which不能省略，而在the one、ones 之后,which可省略。如： ①Their problem today is somewhat similar to that which they faced many years ago. 7）代替不可数名词时，应该用that。如：The equipment is different from that. 8）it代替上文所提到的名词时，是指同类事物中的同一样东西，即同类事物。如： I have lost my pen. I'm looking for it. 9）it和that可代替前面整个句子的意思，而one却不能；that可引导一个限定性定语从句，代替某个先行词（单复数名词均可），it和one则不能；it可代替不定式、动名词或从句，用作形式主语或形式宾语，也可用于强调句型中，而one和that则不能。如： ①-I will make bed for you. –It is very kind of you. ②Jim said he had read my novel.But that was not possible. ③A clock is an instrument that tells time. ④The students that surf the Internet will be punished by the teacher. ⑤It is nice to see you again. ⑥It is no use calling her up. ⑦I found it impossible for me to pass the test. ⑧It was I who broke your window.

不定代词用法归纳
不定代词用法归纳(详细讲解) ■本站特约作者陈根花 一、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, (a) few, (a) 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。 二、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： 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。 【说明】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。如不能说 There are trees on every side of the road. 三、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, no one, 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(参见 any & some)。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： 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：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：
代词one,theone,that及those的用法辨析
李春 【来源：新高考(高三语数外)】 代词辨析实际上是一类比较难的试题，很多同学往往混淆其中难以理清，本文就有关易混的几个代词来作一下重点的剖析并通过强化训练来帮助同学们更好地掌握有关代词的用法: 一、代词one 与the one 的用法 请看以下几个例句: ( 1) It is a very colorful event, one that has become an institution (习俗，风俗) for celebrating the King or Queen’s birthday since 1805. ( 2) Meeting my uncle after all these years is an unforgettable moment, one that I will treasure forever. ( 3) Tom wants to buy a birthday present for his mother, one that is useful but not expensive. ( 4) Never forget that within even the weakest of human bodies lies a life that is precious indeed—one that needs to be respected and honored. 分析通过对以上例句的观察我们可以发现代词one 在以上例句中均充当同位语这一成分，且代词one 后面都有由that 引导的定语从句来修饰，此处为何选择使用one 呢? 因为此处代词one 分别指前文中的a very colorful event，an unforgettablemoment，a birthday present，a life，也就是说one 一词表示泛指( 且只能指代可数名词) , 指代前文中的泛指结构，前文中泛指结构中通常有不定代词a。 请比较下一个例题: All of us have the desire to visit the three main temples in Athens，especially the one that contains a gold and ivory statue of Athena. 分析此例中使用了代词the one，此处的the one 成分也为同位语且后面也跟带有that 引导的定语从句，但是此处的the one 指代的是前文中的the three main temples 中的一座庙，前文所提及的三座庙本为特指，因此后续句中的代词也应使用特指来指代，指雅典的三座庙中的那一座“有金和象牙铸成的雅典娜雕像”的庙。 【典题例析】 Last Sunday, I went shopping for the perfect dress， would make me look younger.( 2009苏州高三调研) A. one in which B. the one in which C. one that D. the one that 分析本例中选择代词the one，因为the one 代替前面的the perfect dress 为特指，因此，此处的同位语使用the one，并且不定代词为先行词后面应使用that 来引导。故答案为D。 二、代词that 的用法 代词that 的指代为特指，并且我们通常归纳为“同物异指”，即代词that 指代的物体与前文中的物体是同样的名称，但是有不同的内涵，另外代词that 可以指代前文中的不可数名词，如: The climate of Jilin is not so mild as that of Jiangsu. 吉林的气候不如江苏温和。
