关于代词that和which的用法区别

关于代词that和which的用法区别：

在定语从句中，当先行词是指物时，关系代词which可以由that代替，如果which不在介词之后，也可省略。在日常用语或口语中，which不作主语时可以省略。例：

Did you take away the book(which/that）I showed you yesterday?

你把我昨天给你看的那本书拿走了吗？

The hotel at which we stayed was both cheap and comfortable.

我们住的那家旅馆既便宜又舒适。

This is certainly not the book for which I paid./This is certainly not the book I paid for.

但两者之间还有一定的区别，必须予以足够的重视。

一.that仅用在限制性定语从句中，通常不用逗号隔开，作宾语或介词宾语时，that 可以省去。例：

我希望我能够做到的那一点点是有些用处的。

This reference book contains much(little)that is useful.

这本参考书中有很多（没有多少）有用的东西。

四.当先行词被形容词的最高级形式所修饰时，要用that, 不用which，作宾语时可以省去。例：

This is the most expensive watch(that)I've ever owned.

这是我有过的最昂贵的一块表。

This is the best article that has ever been written on this subject.

迄今为止在有关这个题目的文章中，这一篇是最好的。

这是我头一次听她唱歌。

说谎话来掩盖我的错误是我最不愿意干的事。

The only thing that matters is to find our way home.

只有一件事最重要，那就是找到回家的路。

六.当先行词被the same修饰时，用that表示同一件物品，用as表示相类似的一件物品，不能用which。例：

This is the same one as/that you had before.

这跟你以前的一样/这就是你以前的那一个。

I saw the mistake at the(very)same moment that she did.

我与她（正好）同时发现错误。

I bought the same car as yours/that you did.

我买的那辆汽车和你的一模一样。

You've made the same mistakes as last time/that you made last time.

你又犯了上次所犯的同一错误。

七.当先行词既指人又指物时，只能用that，不能用which。例：

I like the writers and their works that you mentioned the other day.

我喜欢你前几天提到的那些作家和他们的作品。

They were talking about the persons and things that they remembered in the school.

他们在谈论他们能回忆起来在学校里的人和事。

读一下我在演讲中提到过的那段文章。

His new car, for which he paid ￡7000, has already had to be repaired.

他花700英镑买来的那辆新车已经不得不修理了。

that与which的用法区别

We depend on the land that/which we get our food from.

关系代词which用法说明

关系代词which用法说明 1.既可引导限制性定语从句，也可用作非限制性定语从句。如： This is the photo (that) I took. 这就是我拍的照片。 The river, which flows through London, is called the Thames. 这条流经伦敦的河叫泰晤士河。 2. which引导定语从句时，它在从句中主要用作主语或宾语，但有时也可用作定语，在意义上大致相当于this或that。如： We told him to consult the doctor, which advice he took. 我们叫他去看医生，他听取了我们的劝告。 He is studying economics, which knowledge is very important today. 他学经济学，这种知识现今很重要。注意，它与用作定语的关系代词whose用法不同——whose引导定语从句时，它在意义上大致相当于one’s。如： Wolves are highly social animals whose success depends upon cooperation. 狼是高度群体化的动物，它们的成功依赖于合作。 3.关系代词which原则上只指物，不指人；指人要用who。但是，有时指的不是具体的某人，而是指人的属性（如职业、身份、地位、职务、品质、特征等），则要用which 而不用who。如： He talked like a scholar, which he was not. 他说起话来像个学者，其实他没什么学问。 She talked like a native, which she hardly was. 她说起话来像是个本地人，其实她不见得是。 They accused him of being a traitor, which he was. 他们指控他是叛徒，他真是叛徒。 4.注意不要一看到句前有逗号，就以为一定要用which来引导非限制性定语从句。如以下几句逗号后的that均不能换成which（原因是逗号前的句子为状语从句）：If a book is in English, that means slow progress for you. 如果一本书是用英语写的，那就意味着你要读慢些。 If he’s only interested in your looks, that just shows how shallow he is. 如果他只对你的相貌感兴趣，那就说明他相当浅薄。 When I say two hours, that includes time for eating. 我说两小时，那是包括了吃饭的时间。

定语从句中 which,that 的用法与区别

定语从句中 which,that 的用法与区别只能使用that的情况： 1.当先行词是nothing, something, anything, all, each等不定代词时。 e.g. Do you have anything that is important to tell me? 2.当先行词被all, any, some, no, not, every, each等修饰时。 e.g. I have some books that are very good. 3.当先行词被形容词最高级、序数词(包括last, next等)所修饰时。 e.g. This is the first book that I bought mysel f. The biggest bird that I caught is this bird. 4.主句是以which或who开头的特殊疑问句时 e.g. Which is the bike that you lost? 为了避免重复时用that Who is the woman that was praised at the meeting. 5.当先行词在从句和主句中都作表语时,无论先行词是人还是物. China is no longer the country that she was. 6.如有两个定语从句,其中一个已用which引导,另一个宜用that . Edison built up a factory which produced things that had never been seen before. 7.在there be句型中,只用that. He asked for the latest book (that) there is on the subject. 8.当先行词被the very, the last, the next, the only，the same 等词修饰时。 e.g. This is the very book that I lost yesterday. 9.当先行词又有人又有物时。 e.g. I won’t forget the things and the persons that I saw. 10. 先行词被all, every, no, any, little, some, much等修饰时。 I’ve read all the books that are not mine. 只能使用which的情况。 1、非限制性定语从句(即通常用逗号与主句隔开，如果去掉逗号，整个句子仍能表达完整的意义的定语从句)中。 e.g. Mary has a book, which is very precious. 2、在介词之后。 e.g. This is a house in which lives an old man. 3、当主句中的主语被that修饰时。 e.g. That dog which I found in the street belongs to Mary. 4. 非限定性定语从句修饰的是前面的整个句子，而且关系代词和关系副词前面有逗号, 用which开始的定语从句修饰前面半句 e.g. He will wear no clothes, which will distinguish（区分，辨别）him from his fellow men.

语法中that的用法

“that”在英文中是一个使用频率很高的单词。它有四种词性，并且句法及语法功能纷繁复杂。同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。现将that的用法总结归纳如下：第一、that 用作形容词（后接复数名词时用those）。它用来指已被提到的人或物；也可表对比，指两个中较远的那个。 What about that book you borrowed from me last month？请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。 that little son of his 他那个小宝贝儿子 That George！乔治那家伙！（含有轻蔑语气）第二、that 用作代词。 1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。That is what he told me. What is that (which) you have got in your hand? The price of rice is higher than that of flour. 2. that 用作关系代词，引导限制性定语从句。先行词可人可物，用法相当于who或which。（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时） He talked about the teachers and schools that he had visited. I think it one of the most wonderful films that the film company has ever produced. She has little information that is useful for our research. Is there anything that I can do for you? 请注意，that 在定语从句中作宾语时通常可省略。The books (that) I sent you will help you in your studies. 第三、that 用作连词，引导名词性从句,状语从句和强调句。 1. that名词性从句。 ①引导宾语从句。及物动词后的引导词that可省略。I didn't expect (that) he could win the championship. The teacher pointed out that Tom was not working hard enough. ②引导主语从句。通常采用it作形式主语的句型。 That the earth goes around the sun is known to everyone. （It is known to everyone that the earth goes around the sun.） ③引导表语从句。 The trouble is that we are short of money. ④引导同位语从句。引导同位语从句的that和引导定语从句的that是不同的。前者只起语法作用，在从句中不作任何成分；而后者在定语从句中作主语、宾语或表语。举例说明： The news that he resigned from office surprised us. The idea that he holds is very common nowadays on campus. 2. that引导状语从句①引导目的状语从句。 Bring it nearer that I may see it better. ②引导结果状语从句。What have I done that he should be so angry with me? ③引导原因状语从句。 I am afraid that I will fail in the driving test. ④引导让步状语从句。意为“虽然、尽管”。

There is a teacher who is always ready to help others and who enjoys what he does . 2) 只能用that作为定语从句的关系代词的情况a) 在不定代词，如：anything, nothing, everything, all, much, few, any, little 等作先行词时，只用that，不用which。All that is needed is a supply of oil. Finally, the thief handed everything that he had stolen to the police. b) 先行词有the only, the very, the just修饰时，只用that。He is the very man that helped the girl out of the water . c) 先行词为序数词(the last)、数词、形容词最高级时，只用that。. The first English book that I read was “The Prince and the Pauper”by Mark Twin . d) 先行词既有人，又有物时。He talked about the teachers and schools that he visited . e)当主句是以who 或which 开始的特殊疑问句时，用that 以避免重复。Who is the person that is standing at the gate . f)关系代词在从句中做表语He is not the man that he used to be . 2 、关系副词引导的定语从句关系副词可代替的先行词是时间、地点、方式或理由的名词，在从句中作状语。1)when, where, why，how 关系副词when, where, why,how的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：There are occasions when (on which) one must yield. Beijing is the place where (in which) I was born. Is this the reason why (for which) he refused our offer? I’m surprised the way how (by which) he works out the problem . 注意：①在非限制性定语从句中，"介词+ which"结构不能代替关系副词。如：They set up a state for their own , where they would be free to keep Negroes as slaves . ②含有介词短语的动词一般不能拆开，介词仍放在动词后面。Is this the book which (that) she was looking for ? 3、名词/数词/代词/形容词最高级+ 介词+ 关系代词引导定语从句She has written a book , the name of which I have forgotten . There are fifty-five students in our class , all of whom are working hard . There are five continents in the world , the largest of which is Asia .
