高中英语语法：that和which的用法和区别

that关系代词用法关系代词是英语语法中一个重要的概念，它用于连接主语和宾语，帮助明确句子中主宾之间的关系。

在英语中，常用的关系代词有that、which、who、whom、whose等。

首先，that是关系代词中最常用的一种，它既可以引导定语从句，也可以引导名词性从句。

在定语从句中，that通常用于指代前面提到的名词，例如“The book that I borrowed from the library is very interesting.”（我从图书馆借的那本书很有趣。

）在这个例子中，that指代了前面的名词“book”。

除了指代名词外，that还可以引导名词性从句，例如“I think that she is the best student in our class.”（我认为她是班上最好的学生。

）在这个例子中，that引导了一个宾语从句，作为动词think的宾语。

除了that之外，常用的关系代词还有which、who、whom和whose。

which用于指代前面提到的名词或名词短语，例如“The car which I drive is red.”（我开的车是红色的。

）在这个例子中，which指代了前面的名词“car”。

who用于指代前面提到的名词或名词短语所代表的人，例如“The person who gave me the present is my friend.”（送给我礼物的人是我的朋友。

）在这个例子中，who指代了前面名词“person”所代表的人。

whom用于指代前面提到的名词或名词短语所代表的人，作为宾语，例如“The person whom I met yesterday is my neighbor.”（我昨天遇到的那个人是我的邻居。

）在这个例子中，whom作为动词meet的宾语。

whose用于指代前面提到的名词或名词短语的所有者，例如“The book whose cover is blue is mine.”（封面是蓝色的那本书是我的。

例句：My brother, which is a doctor, works in a hospital.2. 用于代表整个主句的内容有时which可以用来代表整个主句的内容，这种情况下，which后面的动词一般为be动词。

例句：The weather is terrible today, which makes me feel depressed.3. 用于介词后面当which引导的定语从句介词后面是关于整个句子的概括性内容时，我们常使用which。

例句：The book on the table, which I borrowed from the library, is very interesting.二、that的用法1. 用于限定性定语从句限定性定语从句是对名词或代词进行限制性修饰，它不能被省略，通常用that来引导。

定语从句中which that的用法与区别通用版定语从句中which与that的用法与区别定语从句是英语语法中的一个重要部分，用于修饰或限定名词。

其中，which和that是最常用的引导词。

本文将对which和that的用法与区别进行介绍。

一、which的用法1. 限定非限定性定语从句：which用于引导对先行词进行非限制性或限制性修饰的定语从句。

如：- My car, which is red, is parked over there.（非限制性）我的汽车，是红色的，在那边停着。

- The book which you lent me is very interesting.（限制性）你借给我的那本书非常有趣。

2. 代替整个主句的内容：which可以指代先行词所在的句子的全部内容，而非单个词或短语。

如：- The experiment was successful, which made us very happy.实验成功了，这使得我们非常高兴。

- She wanted to travel around the world, which was her lifelong dream.她想环游世界，这是她的终生梦想。

3. 特指事物：which可以用于特指上文已提及的事物。

考点剖析在英语中，关系代词which 与that 均可以引导定语从句，两者有时可以互换，但在某些情况下则不能互换。

对此，笔者剖析了定语从句中关系代词which 与that 的用法，以期能够帮助同学们牢固掌握，避免错用。

一、只用which 的情形(1)在限制性定语从句中，当先行词是those ，that 等，且指物时，其后的关系代词只能使用which ，而不能用that 。

如：①A mall should keep a stock of those goods which sell best.商场应备有畅销商品的存货。

②She admired those which looked beautiful.她欣赏那些看起来很美的东西。

③What is that which is in the basket?篮子里的那个是什么？（2）当关系代词前面出现介词时，且指物时，那么关系代词只能用which 引导，而不能用that 。

如：①That is the house in which Luxun used to live.那是鲁迅过去常住的房子。

②This is the bike by which I used to go to school.这就是我上学时经常骑的自行车。

③The speed with which it is catching up is breathtaking.中国奋起直追的速度是令人惊叹的。

（3）当句子中含有两个定语从句，若一个用关系代词that 引导时，另一个则不能再用that ，而是用关系代词which 。

如：①This is the umbrella that you bor-rowed which you have lost.这就是你借的那把已丢失的雨伞。

②He bought a lot of books that could enrich his knowledge and which could help to kill the time.他买了许多书，这些书可以丰富他的知识，帮助他消磨时间。

如:All that can be done must be done. 凡能做的事都必须做。

This is the only book (that) I find useful.这是我发现的惟一有用的书。

The first thing that you should do is to work out a plan.你应该做的第一件事是订个计划。

(2)引导非限制性定语从句时，有时两者可互换，但若位干主句之前，则只能用as。

定语从句which和 that的用法区别定语从句which和that的用法区别定语从句是英语语法中常见的修饰成分，它可以在句子中作为形容词修饰名词或代词。

在定语从句中，which和that都可以引导从句，但是它们在使用上有一些区别。

本文将详细介绍which和that的用法区别。

一、用法区别：1. 引导非限定性定语从句：which非限定性定语从句是指对名词或代词进行额外的解释或补充，此时只能使用which引导从句。

非限定性定语从句通常使用逗号将其与主句隔开。

例如：The book, which is on the shelf, is mine.（这本书在书架上，是我的。

）2. 引导限定性定语从句：which和that限定性定语从句限定或限制了名词或代词的范围，这时既可以使用which，也可以使用that引导从句。

限定性定语从句通常不能省略，因为它对名词的意义起到了限定作用。

使用which或that时，意义上没有明显的区别。

但在口语中，通常更倾向于使用that。

例如：The book that/which I bought yesterday is very interesting.（我昨天买的那本书非常有趣。

）二、位置区别：1. 使用which引导的定语从句通常可以放在句首或句末，不会影响整个句子的结构。

例如：The car, which was parked outside, caught fire.（停在外面的那辆车着火了。

）The meeting, which will start at 9 o'clock, is important.（将在9点开始的会议很重要。

）2. 使用that引导的定语从句通常放在名词之后，对整个句子的结构有较强的影响。

例如：The book that I bought yesterday is very interesting.（我昨天买的那本书非常有趣。

）The house that Jack built is made of bricks.（杰克建造的那座房子是用砖砌成的。

定语从句which和 that的用法区别通用版定语从句，作为一个重要的语法结构，可以用来修饰名词，进一步描述或限定名词的意义。

在定语从句的表达过程中，我们常常会使用关系代词“which”和“that”。

尽管它们看起来很相似，但它们在使用上有一些细微的差别，本文将对它们的用法进行探讨和总结。

一、用法区别1. “which”的用法“which”常用于非限制性定语从句（non-defining relative clauses）中，用于进一步对前面的名词进行补充解释，但不对前面的名词进行具体的限定。

在这种情况下，定语从句通常放在逗号之后。

例如：- My car, which is blue, was parked outside.（我的车是蓝色的，停在外面。

）在这个例子中，“which is blue”是一个非限制性定语从句，它对前文中提到的“my car”进行补充解释，但不对它进行具体的限定。

2. “that”的用法“that”常用于限制性定语从句（defining relative clauses）中，用于对前面的名词进行具体的限定。

这种定语从句通常不需要用逗号隔开。

例如：- The book that I bought yesterday is very interesting.（我昨天买的那本书非常有趣。

）在这个例子中，“that I bought yesterday”是一个限制性定语从句，它对前文中提到的“the book”进行具体的限定。

二、细微差别虽然“which”和“that”在用法上有一些差别，但在很多情况下它们是可以互换的。

但是，有几个细微的区别需要注意。

1. 逗号的使用在非限制性定语从句中，我们通常使用“which”并在其前后加上逗号。

例如：- My house, which is located in the countryside, is very peaceful.（我的房子位于乡村，非常宁静。

定语从句讲解一、详细的定语从句讲解定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。

状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以及行为方式状语从句。

名词从句包括主语从句，宾语从句，表语从句和同位语从句及there be句型。

（一）限定性定语从句1. that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。

而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语5. where是关系副词，用来表示地点的定语从句6. when引导定语从句表示时间〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导By the time you arrive in London, we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.7. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导（二）非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分2. 在引导限定性定语从句时，that有时相当于in which, at which, for which或at whichAttitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。

定语从句的引导词与关系词的辨析在英语语法中，定语从句是一种用来修饰名词或代词的从句结构。

而在定语从句中，引导词与关系词起着至关重要的作用，它们不仅连接主句与从句，还在从句中充当特定的语法角色。

然而，由于引导词与关系词存在着一定的差异，容易引起学习者的混淆。

本文将对定语从句的引导词与关系词进行详细的辨析和解释。

1. 引导词“that”与关系词“that”的用法区别引导词“that”用于引导定语从句时，可以在从句中做主语、宾语或表语，如:- The book that I bought is very interesting. （引导从句中的主语）- The girl that you met yesterday is my sister. （引导从句中的宾语）- This is the house that I used to live in. （引导从句中的表语）而关系词“that”用于连接主句与从句，起到引导从句的作用。

在这种情况下，关系词“that”在从句中不再充当特定的语法角色。

例如: - He told me that he would come tomorrow. （连接主句与从句）- I know that you like this song. （连接主句与从句）2. 引导词“which”与关系词“which”的用法区别引导词“which”用于引导非限制性定语从句时，可以在从句中做主语、宾语或表语，如:- The book, which is written by a famous author, is very interesting. （引导非限制性定语从句中的主语）- This is my car, which you borrowed last week. （引导非限制性定语从句中的宾语）- The house, which is newly built, is very beautiful. （引导非限制性定语从句中的表语）而关系词“which”用于连接主句与从句，起到引导从句的作用。

只用that不用which的用法探索“that”与“which”的奥秘：只用"that"的用法在英语学习过程中，我们经常会遇到一个令人困惑的问题，那就是如何准确地使用"that"和"which"这两个词。

虽然它们在很多情况下可以互换使用，但在某些特定的语境中，两者之间还是存在着明显的差异。

在这篇文章中，我们将深入探讨只用"that"不用"which"的用法。

首先，我们需要了解的是，“that”和“which”都可以用来引导定语从句，但两者的用法规则却有所不同。

“That”在引导限定性定语从句时，通常不能省略；而在引导非限定性定语从句时，则可以省略。

然而，“which”无论在引导哪种类型的定语从句时，都可以省略。

那么，何时我们应该只用"that"而不使用"which"呢？以下是一些情况：1. 当定语从句是限定性的，并且其先行词是一个事物或抽象概念时，应该使用"that"。

例如："The book that I read yesterday was very interesting."（我昨天读的那本书非常有趣。

）2. 在某些固定搭配中，比如"It's important that..."（重要的是...）和"I'm glad that..."（我很高兴...），只能使用"that"，不能使用"which"。

3. 当定语从句紧跟在其先行词后面，没有逗号隔开时，也应该使用"that"。

例如："I need a pen that writes smoothly."（我需要一支书写流畅的笔。

）4. 当"which"引导的非限定性定语从句位于主句之前时，应改为使用"as"或"which"引导。
