英语语法知识点：关系代词为何用that不用
当定语从句修饰“物”时，关系代词用that不用which，大致有
如下几种情况：
1. 当先行词本身是all, everything, anything, nothing, none, little, few等代词时，关系代词原则上用that，不用which，例如：
In China, parents always do everything that they can to support their children. 在中国，父母总是尽他们所能来抚养孩子。
I did nothing that might hurt you. 我没有做任何可能伤害你
的事。
All that glitters is not gold. 闪光的东西并非都是金子。
2. 当先行词被all, every, no, little, few, the only, the very, the right(恰当的), the last, the same等修饰时，关系代词原则上用that，不用which，例如：
Chatting is the only thing that interests her most. 聊天
是她感兴趣的事情。
These messages are the very ones that I have been looking for. 这些就是我一直在寻找的信息。
This is the last thing that I want to do. 这是我最不愿意
做的事情。
3. 当先行词本身是序数词或形容词级，以及被序数词、形容词级
修饰时，关系代词原则上用that，不用which，例如：
It was the largest map that I ever saw. 那是我见过的的地图。
When it comes to Jinan, the first that comes to mind is
the spring water. 谈到济南时，首先想到的就是泉水。
That is the best film that has ever been shown so far in the city. 那是这座城市到当前为止放过的的一部电影。
【问题探究】
透视上述三种情况，我们发现：一旦先行词或之前的修饰语表达
了①独一无二概念、②全部概念、③完全否定的概念时，也就是说“无需选择或者无法选择”的时候，原则不能使用关系代词which，因为which以前是疑问代词“哪一个”，多少还保留着“选择”的意味。比方说，the only 表示“”，everything表示“所有的东西”，none 表示“什么都没有”，这些还需要选择吗?还能做出选择吗?既然不能
选择或者无法选择，which就别用了。
同理，修饰“人”的定语从句，如果先行词本身或前面的修饰语
跟上述情况相同，那么，同样选择使用that，尽量避免使用who。说
明who这个关系代词仍然带有原来疑问的味道。例如：
Her father was the simplest, hardest working man that we had ever met.
Alice is the only girl that was praised by the headmaster at yes terday’s meeting.
All the passengers that were injured were carried to the hospital
高考英语语法专题复习 三、代词 知识要点： 代词是代替名词、名词短语或句子的词。代词可分为人称代词、物主代词、指示代词、反身代词、不定代词、疑问代词、相互代词、连接代词、关系代词等九类。 一、人称代词 人称代词在句中可以用作主语(用主格，如I, you, he, she, it, we, they, 等)和宾语(用宾格，如me, you, him, her, it, us, them等)： 人称代词的用法: 注：(1)在电话中或It is/was...that/who...强调句型中被强调部分做主语时，用主格： ---Is that Mr. Li? ---Yes. This is he. It’s I who did it. 这是我干的。 (2)单独使用的人称代词通常用宾格： “I’m tired.” “Me too.” “我累了。”“我也累了。”“Who wants this?” “Me.” “谁要这个？”“我要。” (3)有时用主格或宾格会导致意思的变化： I like you better than he. 我比他更喜欢你。为I like you better than he likes you. I like you better than him. 我喜欢你胜过喜欢他。为I like you better than I like him. (4)人称代词的排列顺序：单数人称代词通常按“二三一”排列，即you, he and I； 复数人称代词通常按“一二三”排列，即 we, you and they：You, he and I are of the same age. 你，他和我都是同一年龄。 We , you and they are all good citizens. 我们，你们和他们都是好公民。 但若用于承担责任或错误等场合，则可把第一人称 I 置于其他人称代词之前： Tom and I hope to go there. 汤姆和我想去那儿。I and Tom are to blame. 我和汤姆该受批评。 但是，you and I 是固定结构，语序通常不宜颠倒。 (5)人称代词后跟名词同位语。有些人称代词后有时可跟同位语： These small desks are for us students. 这些小课桌是给我们学生的。 We girls often go to the movies together. 我们女孩子常一起去看电影。 He asked you boys to be quiet. 他要你们男孩子安静些。 二、物主代词 物主代词分形容词性物主代词(my, your, his, her, its, our, your, their)和名词性物主代词(mine, yours, his, hers, its, ours, yours, theirs)。形容词性物主代词相当于形容词，置于名词前，作定语；名词性物主代词相当于“形容词性物主代词+名词”，在句中作主语、宾语、表语、连用of作定语：His son is taller than hers. 他的儿子比她的儿子高。 Ours is a great country. 我们的国家是一个伟大的国家 Her son is a friend of ours. 她的儿子是我们的朋友。 This is your pen. Mine is in the box. 这是你的铅笔，我的在铅笔盒里。 注：(1) a friend of mine (ours, yours, hers, his, theirs)结构 (2) 物主代词与own 连用。表强调。也可用of one’s own置于名词后作定语： Mind your own business. 别管闲事。
高中英语语法总结大全之代词 人称代词的用法 1）人称代词的主格在句子中作主语或主语补语，例如： John waited a while but eventually he went home. 约翰等了一会儿，最后他回家了。 John hoped the passenger would be Mary and indeed it was she. 约翰希望那位乘客是玛丽，还真是她。 说明：在复合句中，如果主句和从句主语相同，代词主语要用在从句中，名词主语用在主句中，例如： When he arrived, John went straight to the bank. 约翰一到就直接去银行了。 2）人称代词的宾格在句子中作宾语或介词宾语，但在口语中也能作主语补语，第一人称在省略句中，还可以作主语，例如： I saw her with them, at least, I thought it was her. 我看到她和他们在一起，至少我认为是她。（her做宾语，them做介词宾语，her作主语补语） a. -- Who broke the vase?--谁打碎了花瓶？ b. -- Me.--我。（me作主语补语= It's me.） 说明：在上面两例句中，her和me分别作主语补语。现代英语中多用宾格，在正式文体中这里应为she和I。 人称代词之主、宾格的替换 1) 宾格代替主格 a.在简短对话中，当人称代词单独使用或在not 后，多用宾语。 ---- I like English.--我喜欢英语。 ---- Me too.--我也喜欢。 ---- Have more wine?--再来点酒喝吗? ---- Not me.--我可不要了。 b.在表示比较的非正式的文体中，常用宾格代替主格。但如果比较状语的谓语保留，则主语只能用主格。 He is taller than I/me. He is taller than I am. 2) 主格代替宾格 a. 在介词but，except 后，有时可用主格代替宾格。 b. 在电话用语中常用主格。 ---- I wish to speak to Mary. --我想和玛丽通话。 ---- This is she. --我就是玛丽。 注意：在动词be 或to be 后的人称代词视其前面的名词或代词而定。 I thought it was she. 我以为是她。(主格----主格) I thought it to be her.(宾格----宾格) I was taken to be she.我被当成了她。(主格----主格) They took me to be her.他们把我当成了她。(宾格----宾格)

You can use hers(=her pen),(作宾语) ③“of+名词性物主代词”属双重所有格的一种形式。 cat of hers她的一条狗,a friend of yours你的一个朋友 3.反身代词 ①反身代词在句中可作同位语，起强调作用，也可作动词或介词的宾语。 few days later,I myself had to go to Paris.(作同位语) She bought herself a new bag.(作动词宾语) He’s not worried about himself.(作介词宾语) ②带有反身代词的常用短语。 teach oneself 自学 help oneself to 随便吃些…吧

高中英语语法知识——代词 英语中的代词，按其意义、特征及在句中的作用分为九种： 人称代词分为主格（如：I, you, he等）和宾格（如：me, you, him） 物主代词分为形容性物主代词（如：my, his, your）和名词性物主代词（如：mine, his, yours） 指示代词常见的有四个：this这，that那, these这些, those那些 反身代词如：myself我自己，himself他自己，themselves他们自己 疑问代词用在特殊疑问句中。有：who, whom, whose, what, which。如：Who is that boy? What do you like? 不定代词如：some一些, many许多, both两个都, everything, everybody等 关系代词引导定语从句。如：This is the boy who won the race. 相互代词指each other 与one another，意为“互相” 连接代词疑问代词在引导从句时，都称为连接代词，包括who, whom, whose, what, which, whoever,whomever, whichever, whatever，一共九个。如： It is clear enough what she meant. 她是什么意思很清楚。（引导主语从句） I don’t care what they think. 他们怎么想我不管。（引导宾语从句）
第1讲人称代词 第2讲指示代词 人称代词分为主格和宾格。 考点1. 代词作同位语 如果代词和名词指代相同时，常用主格或宾格作同位语，不用物主代词。改错：Our Chinese people are friendly. 把our改为we, 因为我们本身就是中国人。 考点2. 用人称代词宾格代替主格的情况 ①口语中作表语的人称代词一般用宾格，不用主格。—Who is it? —It’s me. ②在比较句型中，as和than后的主格可以用宾格代替。I am taller than she/her.He is as tall as she/her. ③ but, except作“除了……”解并且位于主语之后时，后面可以跟主格也可跟宾格。Nobody but/except he/him knew it. ④人称代词单独出现时，常用宾格。Who runs faster, you or me? 考点3. this, that that则指前面讲到过的事物，有承上的作用, this常指后面要讲到的事物，有启下的作用。I want to tell you this: the English party will be held on Saturday afternoon.He hurt his leg yesterday. That’s why he didn’t come.

（2）as与which的区别 a、位置不同 as可放在主句后，主句前或主句中间；which只能放在主句后。 b、as起连接作用，表达说话人的观点、看法，并指出主句内容的根据或出处，意为“正如，正像”。 Which相当于并列句，可以用and this来代替，意为“这一点，这件事’”。 注意：as常用于下列结构：as we know/ as is known to all, as we all can see, as has been said before/above, as might be excepted, as is often the case, 一般不能用which代替as。 c、在从句中作主语时，which既可作系动词be的主语也可作实义动词的主语，而as只可作系动词be的主语。 二、只用that不用which的情况 1、.先行词为all , much, everything, nothing , something ,anything, nothing, none, the one等不定代词时 2、先行词被only, any, few, little, no , all, just , very ,right等修饰时. 3、当先行词是最高级或被形容词最高级修饰时。
