which是一个相对代词，用于连接两个句子或者从句中的名词性词组，以引导另一个定语从句。以下是更为详细解释：1.作为相对代词，which可以引导从句，并在从句中充当主语、宾语或表语等成分。which通常放在定语从句的首部，并指代先行词，进一步为先行词作出解释或说明。2.which引导的定语从句通常放在被修饰的名词性词组之后，如“The book,which is on the desk,is mine.”其中which引导的定语从句修饰了前面的名词词组“the book”，给出了更详细的信息。3.which也可以引导非限制性定语从句，即从句中包含的信息不影响主句对先行词的确认或理解。例如：“I have a new computer,which,by the way,is very expensive.”这里which引导的定语从句起到补充说明的作用。4.在正式的英文写作中，which的使用需要遵循一些基本的规则，如避免使用which引导的定语从句替代限定性定语从句、注意which与that的区别、注意定语从句的位置等。综上所述，which是一个相对代词，用于连接定语从句，进一步为先行词进行解释或说明。which通常放在被修饰的名词性词组之后，并且可以引导限制性定语从句或者非限制性定语从句。在使用which的同时，也需要注意其使用规则以及与其他相对代词的区别。此外，which也可以在口语中用作代替词，表示“哪个”或“那一个”。例如，“I have two apples,which do you want?”这里的which代替了“which apple”，表示对两个苹果进行选择。此时，which不一定必须放在被修饰的名词前面，但需要通过语境来判断其是否代表特定的先行词。总之，which作为相对代词在英语语法中是十分重要的一部分，对于学好英语非常有帮助。

疑问代词 第一句话对…

which的用法四种句型如下：1.which 哪个、哪一个which 用作疑问形容词时，表达选项数目固定或是有限的选项。例：Which time suits you better, 11:30 or one o"clock?哪个时间你更方便——11点半还是1点？例：Which is mine? The smaller one?哪个是我的？小一点的这个？例：Which of these jackets do you prefer?这几件夹克你比较喜欢哪件？2.which 用作关系代名词(接在逗号后面)which 当成关系代名词使用时，用于为前面的从句补充额外资讯，通常用于逗号之后。若which接在逗号后面，which指的是逗号前面所描述的整个事件。例：He showed me round the town, which was very kind of him.他带我参观了这个城镇，他真是太好了。例：She invited us to dinner, which was very kind of her.她邀请我们吃晚饭，她人真客气。3.which 用作关系代名词(前面无逗号)若which前面无逗号，则which指的是前面提到的事物。例：The museum which we visited yesterday is the biggest in the city.我们昨天拜访的博物馆是这城市里最大间的。例：It"s a disease which affects mainly older people.这疾病主要感染的是老人。4.which 的限定用法与非限定用法which当作关系代名词时，要特别注意限定用法与非限定用法。例：Tom has a cat which can sleep all day.汤姆有一只可以睡整天的猫。说明：which前面没逗号，所以which指的是”猫”，表示汤姆可能有很多猫，而这里指的是整天在睡觉的那只猫。这是限定用法。例：Tom has a cat, which can sleep all day.汤姆有一只猫，可以睡整天。说明：which前面有逗号，所以which指的是“汤姆有一只猫”，表示汤姆应该只有这只猫，而这只猫可以睡整天。这是非限定用法。

which的几种指代如下:1、which是一个连接代词,在宾语从句中可以充当主语、宾语或定语;2、which引导非限定语从句，可以指代整个主句，或主句中的某个从句;3、which在定语从句中可指代表语，形容词;4、which在定语从句中指代宾语时，可省略。

　　关系代词 which 一般指物，在定语从句中作主语、宾语或定语，既可引导限制性定语从句，又可引导非限制性定语从句。下面就进行归纳总结： 　　1. 引导限制性定语从句 　　A shop should keep a stock of those goods which sell best. 商店应存有最畅销的货物。 　　This is the family which is planning to move to the party. 这是要搬进城里的一家。 　　2. 引导非限制性定语从句。 　　（ 1 ）用来指代一个句子。 　　Internet is so interesting, which makes all possible happen. 因特网是如此有趣，它使任何事都有可能发生。 　　（ 2 ）用来指代句子的一部分。 　　When deep in thought, which he often was, he would forget all around him. 他常常陷入沉思，这时他就会忘掉周围的一切。 　　（ 3 ）如果要引导两个非限制性定语从句，第二个 which 前要加 and. 　　He bought a book, which was written by LuXun, and which he decided to give to his friend. 　　他买了本鲁迅写的书，他决定送给朋友。 　　3. 名词＋ of ＋ which （＝ of which ＋名词＝ whose + 名词）通常放在先行词的后面。 　　I"d like a room the window of which looks out over the sea. / I"d like a room of which the window looks out over the sea. / I"d like a room whose window looks out over the sea. 　　我要一间窗户面临大海的房间。 　 　4. 介词＋ which 的替代作用。 　　（ 1 ）作时间状语替代 when 。 　　There used to be a time at which / during which （ = when ） the Chinese people struggled for freedom. 　　中国人曾有一段为自由而斗争的日子。 　　（ 2 ）作地点状语替代 where 。 　　This is the office in which （ = where ） I used to work. 这是我过去工作过的办公室。 　　（ 3 ）作原因状语替代 why 。 　　I"d like you to explain the reason for which （＝ why ） you were absent. 我想让你解释一下缺席的原因。 （ 4 ）作方式状语替代 that 或省略。 　　There are many ways in which （＝ that / 省略） we can solve the problem. 解决这个问题有很多方法。 　　5. which, when, where 关系词的选择。 　　关系副词 when 与 where 用于引导定语从句时，往往修饰句中表示地点或时间的名词。但是，有时候在表示时间或地点的名词后面却不能用 when 或 where ，而该用 which 或 that 。 　　Is this the factory which / that produces all kinds of washing machines? （ which / that 在定语从句中作主语，指代前面的 the factory ）这就是生产各种洗衣机的那家工厂吗？ 　　I often think of the days which / that we spent together on the seaside. （ which / that 在定语从句中作宾语，指代 the days ，此时可省略。）我经常想起我们一起在海滩度过的日子。 　　The river where I used to swim is now seriously polluted. 　　（ where 在定语从句中作状语， where = in which = in the river ）我过去常去游泳的那条河现在已被严重地污染了。 　　I still remember the day when I first came to Beijing. 　　（ when 在定语从句中作状语， when = on which = on the day ）我仍然记得我第一次来北京的日子。 　　总结：在表示时间或地点的名词后面，选择何种关系词，应看它们在从句中的作用，即在从句中充当什么成份。如果在定语从句中充当时间或地点状语，就该用 when 或 where ；如果在定语从句中充当主语或宾语等，则应用 which / that 。 　　6. 引导非限制性定语从句关系代词 which, as 的选择。 　　关系代词 as 与 which 引导非限制性定语从句时可以用整个句子作为先行词，指代上文或下文所说的一件事。 　　He said he"d been working in the office for an hour, which / as was true. 他说他一直在办公室工作了一个小时，这是真的。 总结： 　　（ 1 ） Which 指前面主句所提到的"这件事，常译为“这件事，这一点”等； as 具有“正如、像、由而知、与一致”的意思。 　　He was elected mayor of the city, which made us happy. 他被选为这个市的市长，这使我们很高兴。 　　As we expected, he didn"t appear at the party. 正如我们所预料，他没有在聚会上出现。 　　（ 2 ） Which 在句法上一般用作实义动词的主语，这时它所引导的从句与主句之间常含有并列、因果关系；句法上， as 常作一些实义动词（如 see, know, report, watch, remember, say, tell, show, expert, guess 等）的宾语。 　　I bought my sister a big toy, which （ = and that ） delighted her greatly. 我给妹妹买了一个大玩具，这使她非常高兴。 　　As is known to everybody, the moon travels round the earth once every month. 众所周知，月球每个月环绕地球运行一次。 　　（ 3 ） which 引导的非限定性定语从句位置比较固定，通常位于句末，不可移至句首；而 as 所引导的非限定性定语从句的位置比较灵活，可以位于句末，也可以位于句首或句中。 Taiwan is a beautiful island, as （＝ which ） we know. 正如我们所知，台湾是一个美丽的岛屿。 　　As （不用 Which ） he realized, I was very useful to him. 他意识到我对他很有用。 　　Mary, as we had expected, passed the exam. 正如我们所预料， Mary 通过了考试。 　　（ 4 ）当从句的谓语动词是否定形式或从句谓语动词接了一个复合宾语结构时，一般用 which 而不用 as 。 　　He pretended not to know me, which I didn"t understand. 他假装不认识我，我真不明白为什么。 　　He admires everyone in the class, which I find quite strange. 他羡慕班里的每个学生，我觉得很奇怪。 　　（ 5 ）不能省去非限定性定语从句中的 be 动词时，用 which （反之则用 as ）。 　　Jane told me she won the match, which was a lie. 简告诉我她赢得了比赛，这是谎话。（ was 不可省略） As (was)planned, we met at the airport. 　　正如计划那样，我们在飞机场见面了。（ was 可省略）

Which is the book that you like best?2. Who is the man that is standing at the gate?⑨主句是There be 结构,修饰其主句的定语从句宜用that 作关系代词. 如：1. There is still a seat in the corner that is still free.⑩被修饰成分为表语时,或者关系代词本身是定语从句的表语时,该关系代词宜用that . 1. That"s a good book that will help you a lot.2.

1、at which：在...，关系代词用作主语或宾语。2、in which：在...里面，多用在书面语中。3、on which：在...上面，由介词加上关系代词来引导。4、for which：为了...，从句由介词加上关系代词来引导。5、by which：用...，非限制性定语从句所修饰的是物。6、from which：从...，非限制性定语从句所修饰的是整个主句。扩展资料which的用法：1、which用作疑问代词时，在特殊疑问句中用作宾语或主语。2、which用作关系代词，可引导限制性定语从句或非限制性定语从句。3、引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that，有时还可引导不定式短语从句。4、直接源自古英语的hwilc，意为哪一个。

1、which的用法，主要用作代词、限定词、形容词，作代词时意为“ 哪一个，哪一些;(指明事物)……的那个，……的那些;(进一步提供有关某事物的信息)那个，那些”，作限定词时意为“ 哪一个，哪一些;(指明事物)……的那个，……的那些;(进一步提供有关某事物的信息)那个，那些”，作形容词时意为“哪一个，哪一些;无论哪个;(进一步提供有关某事物的信息)那个，那些”。 2、双语例句：You love that but I love which.你喜欢这个，而我喜欢这个。

which引导定语从句。which前面加介词时时在句子里做宾语。如果从句中是动词短语作谓语，打动词短语中的介词就可以前置，放在which前边。例:Ifoundthatboxinwhichmybookswereput.在从句里应该是Mybookswereputinthebox.介词in便可以变在从句时前置。以下是些定从的用法。．词引导的定语从句1.关系代词用来指代先行词是人或物的名词或代词句子成分用于限制从句或非限制性从句只用于限制性从句代替人代替物代替人或物主语Whowhichthat主语Whomwhichthat宾语Whose(=ofwhom)whose(=ofwhich)例1：ThisisthedetectivewhocamefromLondon.例2：ThebookwhichIamreadingiswrittenbyTomasHardy.例3：Thedeskwhoselegisbrokenisveryold.例4：ThisistheroomthatShakespearewasbornin.2．关系代词的用法(1)如果先行词是all,much,anything,something,nothing,everything,little,none等不定代词，关系代词一般只用that，不用which。例如：Allthepeoplethatarepresentburstintotears.(2)如果先等词被形容词最高级以及first,last,any,only,few,mush,no,some,very等词修饰，关系代词常用that,不用which,who，或whom。例如：(3)非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。例如：Thereareaboutsevenmillionpeopletakingpartintheelection,mostofwhom、arewelleducated.(4)which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与andthis相似，并可以指人。例如：Hesucceededinthecompetition,whichmadehisparentsveryhappy.(5)that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。(6)which可作表语，既可指人，以可指物。指人时，一般指从事某种职业或是有种特征．品性或才能的人。Which引导的定语从句可以限制性的，也可以是非限制性的。(7)如果作先作词的集体名词着眼于集体的整体，关系代词用which;若是指集体中的各个成员，则用who。(8)先行词有两个，一个指人，一个指物，关系代词应该用that。例如：Theboyandthedogthatareinthepictureareverylovely.(9)如果先行词是anyone,anybody,everyone,everybody,someone,somebody,关系代词应该用who或whom，不用which。例如：Isthereanyoneherewhowillgowithyou?3．“介词＋关系代词“是一个普遍使用的结构(1)“介词＋关系代词“可以引导限制性定语从句，也可以引导非限制性定语从句。“介词＋关系代词“结构中的介词可以是in,on,about,from,for,with,toat,of,without等，关系代词只可用whom或which,不可用that。(2)fromwhere为“介词＋关系副词“结构，但也可以引导定语从句。例如：Westoodatthetopofthehill,fromwherewecanseethetown..(3)像listento,lookat,dependon,payattentionto,takecareof等固定短语动词，在定语从句中一般不宜将介词与动词分开。例如：Thisistheboywhomshehastakencareof.二．关系副词引导的定语从句1．关系副词也可以引导定语从句关系副词在从句中分别表示时间．地点或原因。关系副词when在从句中充当时间状语，where充当地点状语，why充当原因状语。2.that可引导定语从句表示时间．地点或原因That有时可以代替关系副词when,where或者why引导定语从句表示时间．地点或原因，在that引导的这种定语从句中，that也可以省去。三．限制性定语从句与非限制性定语从句1．二者差异比较限制定语从句紧跟先行词，同先行词这间一般不加逗号，仅修饰先行词，可以由关系代词．关系副词或that来引导。非限制性定语从句仅作补充或说明，用逗号与主句隔开，既可修饰先行词，又可修饰整个主句，不可用that引导。2．关系代词和关系副词的选择依据(1)弄清代替先行词的关系词在从句中作什么成分,作状语的应选用关系副词，作主语．宾语或表语的可选用关系代词。3.先行词与定语从句隔离定语从句一般紧跟在先行词之后，但定语从句与先行词之间有时也会插入别的成分，构成先行词与定语从句的隔离。例如：1)ThisisthearticlewrittenbyhimthatIspoketoyouabout..2)Hewastheonlypersoninthiscountrywhowasinvited四．As在定语从句中的用法1.引导限制性定语从句和非限制性定语从句（1）as多与such或thesame连用，可以代替先行词是人或物的名词。（2）as也可单独使用，引导非限制性定语从句，作用相当于which。例如：Theelephant"snoseislikeasnake,asanybodycansee.3）thesame…that与thesame…as在意思上是不同的。2．As引导的非限制性定语从句的位置as引导的非限制性定语从句位置较灵活，可以位于主句前面．中间或后面，一般用逗号与主句隔开，但which所引导的非限制性定语从句只能放在主句之后。例如：(1)Asisexpected,theEnglandteamwonthefootballmatch.(2)Theearthrunsaroundthesun,asisknownbyeveryone.

你问的是which 用于定语从句中的用法吧？关于which 的用法可以总结如下：一 which可以引导定语从句， 修饰表示事物的先行词， 在定语从句中充当主语、 宾语或者表语。例如： He was reading a book, which was about war. 他正在读一本关于战争的书。（关系代词which在修饰book的定语从句中充当主语。） 　　He was reading a book, which he had bought from London. 他正在读一本书， 这本书是从伦敦买回来的。（关系代词which在修饰book的定语从句中充当宾语。） 二which引导非限定性定语从句时有一个特殊用法， 即它所引导的非限定性定语从句修饰主句中更多的部分甚至整个主句（这时被定语从句所修饰的“先行词”要作广义理解）， which仍在定语从句中作主语、 宾语或表语。例如： 　　He set free the birds happily， which was a celebration for his success. 他开心地把鸟放了， 这是对他成功的一种庆祝。 　　把非限定性定语从句“which was a celebration for his success”的先行词视为主句中的“the birds”显然不符合整句的语境， 被“which was a celebration for his success”所修饰的是整个主句， which所引导的这类特殊的非限定性定语从句对主句所叙述的情况进行某种意义的补充说明， which常可译为“这一点， 这件事”。

which one do you like ? 比如这里的one 就是一个名词

定语从句中只能用which，不能用that的几种情况：1、 在介词后面的关系代词用which而不能用that。即“介词+which（代物）” 。2、 在非限定性定语从句中用which，不能用that。3、有两个定语从句，其中一个关系代词已有which，另一个宜用that。相反，如果其中一个为that，另一个宜用which。4、描述句中一般用which。5、those +复数名词之后，多用which 。6、which用作疑问代词时，在特殊疑问句中用作宾语或主语。7、which用作关系代词，可引导限制性定语从句或非限制性定语从句。8、引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that，有时还可引导不定式短语从句。系词的选择主要涉及以下因素：1、先行词是人还是事物。2、关系词在关系从句中的句法功能。3、关系从句是限制性的还是非限制性的。4、是口语还是书面语。

which在名词性从句的用法：1.宾语从句which是一个连接代词,在宾语从句中可以充当主语，宾语或定语。意思是“哪一个”如：I don"t know which bike belongs to my father.I wonder which is better ,this one or that one?He asked me which I liked best. 2.主语从句which 在主语从句中的用法与宾语从句相类似。which boy she likes best is still a mystery.Which students will be sent to take part in the sports meeting hasn"t been decided.3.表语从句which 在表语中的用法与主语从句和宾语从句的用法也相似。如：His question is which student is the best at English. The question is which place he wants to go to .4.同位语从句which在同位语从句中的用法不多，只用在某些名词的后面，常见的有idea。I have no idea which picture is the most beautiful of all.顺便讲一下，what引导的名词性从句，也是连接代词，但表示的是泛指的东西；which指的是在一定的范围内，哪一个。

关系代词which可以用于引导定语从句。（注意：只用于指事物，不用于指人！！！）例句：She was not on the train which arrived just now. 她不在刚才到达的那列火车上。

根据意思啊in/at which 在哪里fou which 为了某··

which可以引导定语从句， 修饰表示事物的先行词， 在定语从句中充当主语、 宾语或者表语。例如： He was reading a book, which was about war. 他正在读一本关于战争的书。（关系代词which在修饰book的定语从句中充当主语。） He was reading a book, which he had bought from London. 他正在读一本书， 这本书是从伦敦买回来的。（关系代词which在修饰book的定语从句中充当宾语。） （1）在非限定性定语从句中，只宜用which, 不宜用that.（非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若将非限定性定语从句放在句子中间，起前后都需要用逗号隔开。翻译成人类的语言就是：有逗号的句子…）例句：Beijing, which is the capital of China, is a very beautiful city.（2）在限定性定语（就是正常的句子）从句中which和that在指代物的时候常常可以通用，但是有时只宜用which而不用that 。 关系代词前面有介词的时候 （也就是说，有介词就不能用that) 例句：This is the hotel in which you will stay. （3）"介词+关系代词"引导的定语从句关系代词(基本上除了when, where, why, how以外都叫关系代词……）whom, which在定语从句中作介词的宾语时,可以跟介词一起放在主句和从句之间;当先行词指人时,介词后的关系代词用whom, 其余用which,这时的关系代词不能省略。含有介词的短语动词一般不拆开,介词仍放在动词的后面。例句：his is the book (which / that) I"m looking for. 这就是我在找的那本书。在这类定语从句中,介词的选择一般根据动词的需要。例如 This is the house in which my family lived during the war.这个句子中从句"which my family lived"中的动词是live,你不能说livehouse吧,只能说live in house,这里live和in搭配所以which前就要家in.（4）所以说你想要知道到底which前用不用加介词和加什么介词主要有两点:1是你要看这个从句缺不缺介词,2是要看动词与介词的固定搭配,这就是要背的了.例句：This is the girl which I like.这句就不缺介词,你可以把句子反过来看看通不通顺.反过来就是I like this girl.这个句子是对的,不缺成分,那么它也就不用加介词.This is the question about which I always think.这句就是think about 这个词组的搭配了。一般考试会出现的就是live in, think about, hold on 之类的了.

　　which和that的区别：　　1、只用which,不用that的情况。　　1)which可用在非限制性定语从句中。例如：　　The project,which lasted four years,cost one billion dollars.这项工程历时四年，耗资十亿美元。　　2)which可用前置介词宾语。例如：　　This is the house in which we lived three years ago.这是我们三年前住过的那所房子。　　2、只用that，不用which的情况。　　1)that相当于关系副词when,where,why,in the way＝in which。例如：　　I"ll never forget the Monday that /when you first arrived.我将永远不会忘记你初到的那个星期一！　　Do you know anywhere that I can get fruit?　　你知道我能在哪里买到水果吗？　　I like the place for the very reason that/why you dislike it.我喜欢那地方的原因，恰恰是你不喜欢它的原因。　　He doesn"t see things the way that /in which we see them.他看问题跟我们不一样。　　2)that既可指物，也可指人。例如：　　The people that worked on the project made a good effort.从事那项工程的人们做了很大努力。　　3)当主句以here,there开头时，常用that。例如：　　Here is the place that you"ve been looking for.这就是你一直找的地方。　　4)当先行词是序数词、形容词最高级或先行词被序数词或形容词最高级修饰时，常用that。例如：　　The first(thing)that should bed one is to get the book.应该做的第一件事是弄到那本书。　　This is the best place that I"ve ever visit-ed.这是我曾参观过的最好的地方。　　5)当先行词是all,anything,nothing(something除外),none,little,much时，常用that。例如：　　Is this all that"s left?这就是剩下的所有东西吗？　　Have you got anything that belongs tome?你有没有拿过属于我的东西？　　6)当先行词被no,little,only,very,the last等修饰时，常用that。例如：　　The only thing that could be done is to find　　our way home.唯一能做的事情就是要找到回家的路。　　7)当先行词是两个或两个以上的词分别表示人和物时用that。例如：　　They talked about the teachers and the schools that they knew.他们谈到了他们熟悉的老师和学校。　　8)在以which，who开头的句子中常用that。例如：　　Which is the car that killed the man?撞死那个男子的小车是哪一辆？　　9)time是先行词时，前面如有序数词或last修饰时，定语从句只能用that引导或省略。例如：　　This is the last time(that)I shall give you a letter.　　The first time(that)I saw him was last year.

定语从句 （一）定语从句一般由关系代词和关系副词引导1、关系代词：who,whom,whose,which,that,as2、关系副词：when,where,whyP.S ：关系代词和关系副词必须位于从句之首，主句先行词之后，起着连接先行词和从句的作用，同时在从句中又充当句子成分。e.g.She is the girl who sings best of all.（关系代词who在从句中作主语）The comrade with whom I came knows French.（whom在从句中作介词with的宾语）3、关系代词和关系副词的用法：1）当先行词为人时用who作主语，whom作宾语；2）当先行词为物或整个句子时用which，可作主语或宾语；3）先行词为人、物时用that，可作主语或宾语；4）whose用作定语，可指人或物；5）关系副词when（指时间，在定语从句中作时间状语，where（指地点，在定语从句中作地点状语），why（指原因，在定语从句中作原因状语）。（二）限制性定语从句与非限制性定语从句1、限制性定语从句：从句与主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。e.g.I was the only person in our office who was invited.（去掉定语从句，意思就不完整）2、非限制性定语从句：从句对先行词关系不密切，去掉定从句，意思仍然完整。形式上用逗号隔开，不能that用引导。e.g.Tom"s father,who is over sixty,still works hard day and night.（who引导非限制性定语从句，整个句子可分成两句来翻译）（三）使用定语从句时特别注意的几个问题1、that与which的区别。1）用that而不用which的情况：①先行词为不定代词all,anything,nothing,…；②先行词有最高级修饰，有序数词修饰；③先行词有only,very,any等词修饰；④先行词既有人又有物时。e.g.There is nothing that can prevent him from doing it.没有什么能阻止他不干那件事。The first place that they visited in Guilin was Elephant Trunk Hill.在桂林他们所参观的第一个地方是象鼻山。This is the best film that I have ever seen.这部电影是我看过的最好的一部。Mr Smith is the only foreigner that he knows.史密斯先生是他认识的唯一的外国人。2）用which而不用that的情况：①引导非限制性定语从句；②代表整个主句的意思；③介词+关系代词。e.g.He had failed in the maths exam,which made his father very angry.他数学考试没有及格，这使他的父亲很生气。This is the room in which my father lived last year.这是父亲去年居住过的房子。3）as引导定语从句时的用法①as引导限制性定语从句通常用于thesame…as,such…as结构中。e.g.I want the same shirt as myfriend"s.我要一件跟我朋友一样的衬衫。Such machines as are used in our workshop are made in China.我们车间使用的这种机器是中国制造的。②as引导非限制性定语从句既可放在主句之前，也可放在主句之后，用来修饰整个句子。通常用下列句型：as is known to all,as is said,as is reported,as is announced,as we all know,as I expect等。e.g.As I expected,he got the first place again in this mid-term examination.正如我所预料的那样，他在这次期中考试中又获得了第一名。3）as引导非限制性定语从句时与which的区别①当主句和从句语义一致时，用as；反之，用which来引导非限制性定语从句。e.g.He made along speech,as we expected.He made along speech,which was unexpected.②当非限制定语从句为否定时，常用which引导。e.g.Tom drinks a lot everyday,which his wife doesn"t like at all.2.关系代词在从句中作主语时，从句的谓语动词单数还是用复数应由先行词决定。e.g.The man who lives downstairs speaks English fluently.住在楼下的那个人英语说得很流利。 The students who are in GradeThree are going to climb the hill tomorrow.3.定语从句有时不直接紧靠先行词，中间由一个定语、状语或谓语隔开。e.g.There is an expression in his eyes that I can"t understand.4.引导定语从句的关系副词有时可以用“介词+which”来代替。e.g.October 1,1949 was the day on which(=when)the People"s Republic of China was founded.5.当定语从句中谓语动词是带介词或副词的固定短语动词时，短语动词的各个固定部分不要拆开。e.g.The sick man whom she is looking after is her father.6.介词在关系代词前，只能用which和whom，且不能省略；介词在句尾，关系代词可有which,that,whom,口语中也可用who，且可省略。e.g.The man(whom/who/that)you were talking about has come to school.一、什么是状语从句？ 用一个句子（从句）来作另一个句子（主句）的状语，用作状语的句子就叫作状语从句。作什么样的状语就叫什么类型的状语从句。例如：条件状语从句就是用一个句子来作条件状语。 二、状语从句的分类。 （1）时间状语从句用法要点 凡是从句都必须有引导词，引导时间状语从句的词有when，before，after，until，as soon as，while 等，具体用法如下： 1. when 意为“当……时”，引导时间状语从句，表示主句的动作和从句的动作同时或先后发生。例如： I feel very happy when you come to see me. 你（们）来看我时，我感到很高兴。 When you are crossing the street，you must be careful. 你（们）过街道时，一定要小心。 when引导的时间状语从句，when的从句可以用延续性动词，也可以用点动词。eg. He was working at the table when I went in. 当我进去的时候，他正在桌旁工作。 Someone knocked at the door when I was sleeping. 当我正在睡觉时，有人敲门。 I will visit my good friend when I have time. 当我有空儿时，我将去看望我的好友。 I worked for a foreign company when I was in Shanghai. 当我在上海时，我为一家外国企业工作。 注：when也可以作并列连词，表示一个动词正在进行的时候，突然间发生了另外一件事。eg. I was fishing by the river，when someone called for help. 我正在河边钓鱼，就在那时有人求救。 We were working in the chemistry lab，when the lights went out. 我们正在化学实验室工作，突然灯都熄灭了。 2. before 意为“在……之前”，引导时间状语从句时，表示主句的动作发生在从句的动作之前。例如： We cleaned the classroom before we left school yesterday.昨天离开学校之前，我们打扫了教室。 He had been a cook before he went to college . 他上大学前曾当过厨师。 after 意为“在……之后”，引导时间状语从句时，表示主句的动作发生在从句的动作之后。例如： After you use plastic bags，you mustn"t throw them about. 你（们）用过了塑料袋之后，不准到处乱扔。 He called me after he had finished his work. 他在工作完之后给我打了个电话。 注：若主句和从句两个动作发生的先后顺序十分接近，那么也可以不用完成时态，例如上面的第二句可改成：He called me after he finished his work. 3. since引导的时间状语从句，译为“自从……”，主句常用现在完成时，从句常用一般过去时。eg. We have made many dumplings since we began to cook. 自从我们开始做饭起，我们已经包了许多饺子了。 We haven"t seen each other since we parted . 我们自从分手以后一直没见过面。 注：常用句型：It is +时间段+since从句 译为：自从……有多长时间了。eg. It is six years since she graduated from the university. 自从她大学毕业已有六年的时间了。 4. until 意为“直到……时”，引导时间状语从句时，表示主句的动作发生在从句的动作之前。 当主句的谓语动词是持续性动词时，主句常用肯定形式；当主句的谓语动词是非持续性动词时，从句常用否定形式，not…until… 意为“直到……才……”，这时的until可以用before 来替换。例如： I"ll stay here until you come back. 我会呆在这里，直到你回来。（stay表示的动作可以持续） He didn"t go to bed until he finished his homework.他直到做完作业才睡觉。（go to bed 表示的动作不能持续） 5. as soon as 意为“一……就……”，表示从句的动作一发生，主句的动作马上就发生。例如： I"ll tell him about it as soon as he comes back.他一回来我就告诉他这件事。 6. while引导的时间状语从句，常译为“与……同时，在……期间”，while的从句中常用延续性动词或表示状态的词。eg. They rushed in while we were discussing problems. 当我们正在讨论问题时，他们冲了进来。 Father was cleaning the car while I was playing computer games. 当我正在打电子游戏时，爸爸正在清洗汽车。 注：while也可以作并列连词，表转折的关系，相当于but，译为“然而”。eg. I like listening to music，while my brother likes doing sports. 我喜欢听音乐，而我的兄弟爱好运动。 7. till和until引导的时间状语从句，译为“直到……为止”，not … till / until引导的时间状语从句，译为“直到……才”。前者强调主句动作的结束，用延续性动词，后者强调主句动作的开始，用点动词。eg. I will wait for my friend until / till he comes. 我要一直等到我朋友来。 We won"t start our discussion until / till he comes. 我们要等到他来了，再开始我们的讨论。 （2）条件状语从句用法要点 我们主要看一下由if引导的条件状语从句。if 意为“如果”，引导条件状语从句时，表示假如有从句的动作发生就（不）会有主句的动作发生。例如： If it doesn"t rain tomorrow，we will go there by bike.如果明天不下雨，我们就骑自行车去那里。 If I get there early，I can see the doctor quickly.如果我早早地到那里，我就可以快点看病。 （3）地点状语从句用法要点 常用where（哪里）和wherever（无论哪里）eg. Where there is a will，there is a way. 有志者，事竟成。 We will go wherever the motherland need us most. 我们要到祖国最需要的地方去。 （4）原因状语从句用法要点 常用的引导连词有because，as和since，三者的区别是：在回答问题的时候，使用because；对于显而易见的原因，常用as或since；as和since的从句常放在主句之前，而because的从句常放在主句之后。eg. Why did you go？ I went because Tom told me to go. 你为何去？那是因为汤姆叫我去。 He was angry not because we were late but because we made a noise. 他很生气不是因为我们来迟了，而是因为我们弄出了声音。 As it was raining hard，we had to be indoors. 由于雨太大，我们只好呆在家里。 Since you feel ill，you"d better not go to work. 既然你感觉不舒服，你最好不要去上班了。 （5）目的状语从句用法要点 常用的引导连词有so that，that和in order that译为：以便，为了，目的是。eg. Please speak more slowly so that we can make full notes. 请讲慢一点，以便我们能作详细笔记。 I shall write down your address that I may not forget. 我要把你的地址记下来，以免忘记。 I sent the letter by air mail in order that it might reach him in time. 这封信我以航空信发出，以便他能及时收到。 注：目的状语从句可以用动词不定式来替换做目的状语。eg. We work harder than usual finish it in a week. 我们比平常加倍努力工作以在一周内完成工作。 三、主句与从句时态一致的问题。 在时间状语从句和条件状语从句中，主句和从句之间的时态一致问题一般分下列两种情况： 1. 若主句是祈使句，或主句中有情态动词，或主句中谓语动词是一般将来时，那么从句用一般现在时表示一般将来时。例如： Be careful when you cross the road. 过马路时要小心。 Put up your hand if you have any questions to ask. 如果你们有问题要问的话，请举手。 The traffic must stop when the lights are red. 红灯亮时，车辆必须停下。 2. 若主从句谓语动词都是陈述过去，那么主从句都可以用一般过去时。例如： She could sing when she was four years old. 她四岁的时候就会唱歌。 总之是定从这块的知识

定语从句：定语从句（AttributiveClauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。关系代词有：who,whom,whose,that,which等。关系副词有：when,where,why等。题目答案which,这是定语从句what,这是表语从句that,主语从句what,还是主语从句,因为what=allthat

which在从句中做主语、宾语、表语等；in which=where，在从句中相当于地点状语，先行词是地点。如：This is the city where/in which I met John.此处的which指the city，.This is the city which held the Olympic Games.

1 关系代词作介词宾语,即 介词+关系代词,指物只能用whichLast night I had a dream in which I became a Nobel Prize winner.2 非限制定语从句中,指物只能用which,亦可指整个前面的句子.He reads English every day,which does good to his English study.只用that1 先行词为不定代词:one much everything all any ...2 先行词被形容词最高级所修饰3 先行词被序数词所修饰4 先行词由only ,just ,very,right等修饰5 在以which 开头的特殊疑问举重,避免重复用that.6 先行词在从句中担任表语,从句的关系词用thatwhat 一般指代主语

这几个词都可以引导定语从句，that什么时候都可以用。who,whose,whom区别主要在于它的意思上，who表示谁在从句中做主语，whom是它的宾格，在从句中做宾语，whose是谁的，它所代替的应该是一个物主代词或有名词所有格，例如：The girl who helps me is my sister.who做的是help的主语； The girl whom I help is my sister.whom 做的是help 的宾语；The girl whose bag is red is my sister.whose 代替的是the girl"s.The woman who (that) is speaking to my teacher is my mother.The woman whom my teacher is talking with is my mother.The woman whose girl is my classmate is my teacher.

介词+which引导从句，相当于疑问副词。where=in/on/atwhich如,Thisistheshopinwhichiworked.翻译为这就是我以前工作的那个商店。这个是他的主要用法还有其他比较少见的，ofwhich，thequestionofwhichwethoughtissolved。翻译为我们考虑的那个问题被解决了。其实你把句子还原成一般陈述语序就很好理解的。希望对你有帮助

关系代词who、which作主语时，谓语动词的人称、单、复数与先行词必须一致，当先行词为单数时用which is，先行词为复数，则用which are。如：Thomas is one of the boys who are fond of sports.I know a boy who is good at surfing the Internet.Adults don"t like children who tell lies.

肯定是不可以的。这里which是引导定语从句，是怪味道让他相信，换成and，句法不通he convinced him变成什么玩意。

in which, for which, on which, at which的不同用法1)这些都是定语从句里面，由which引导的定语从句，介词提前。下面这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。①in which可以翻译成在……里面The school (that/which) he once studied in is very famous.= The school in which he once studied is very famous.②for which可以翻译成为了……目的Tomorrow I will bring here a magazine (that/which) you asked for.= Tomorrow I will bring here a magazine for which you asked.③on which可以翻译成在……的上面，或具体时间的某一天I have a dresser in my bedroom, which there are many cosmetics on.= I have a dresser in my bedroom on which there are many cosmetics.④at which可以翻译成在……里面或在……The dumpling House which he often has dumplings at is very popular.= The dumpling House is very popular, at which he often has dumplings.2)当然第一点只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。①The plane may be several hours late, in which case there"s no point in our waiting.(固定搭配：in the case)②The speaker paused to examine his notes, at which point a loud crash was heard.(固定搭配：at the point)③Ten years of hard work changed her greatly, for which reason he could hardly recognize her at first sight.(固定搭配：for the reason)④The film at which I fell asleep was very boring.(Here "at which" is based on "fell asleep at the film"因为电影无聊而睡觉。)⑤The little creature in which scientists are interested is known as ET.(这里"be interested in"是词组原因)⑥This is the book for which he is looking.(即等于This is the book which he is looking for，这主要是因为look for 这一短语)关系副词与“介词+which”的区别引导定语从句时where与in which有时可互换，有时不能互换，注意以下几点：一、关系副词与“介词+which”互换的情形当“介词+ which”在定语从句中作时间、地点和原因状语时，可以用相应的关系副词when, where和why来替换。1. when根据情况可以等于in which, at which, on which等。如：The day when (=on which) she arrived was Thursday. 她到的那天是星期四。2. where根据情况可以等于in which, at which, on which等。如：This is the hotel where ( =in which / at which) they were staying. 这就是他们当时住的旅店。3. 关系副词若要换成“介词+which”只能是for which。如：The reason why (=for which) I came here was to be with my family. 我到这里来的原因是要跟我的家里人在一起。

　　现如今，英语也是非常重要的语言，下面是我收集整理的用which造句定语从句，希望大家喜欢。 　　which 　　指物,在定语从句中做主语或者宾语,做宾语时可省略 　　(1) Football is a game which is liked by most boys. 　　(2) This is the pen (which) he bought yesterday. 　　关系代词在定语从句中做介词宾语时,从句常由介词+关系代词引导 　　(1) The school (that/which) he once studied in is very famous. 　　(2) The school in which he once studied is very famous. 　　(3) Tomorrow I will bring here a magazine (that/which) you asked for. 　　(4) Tomorrow I will bring here a magazine for which you asked. 　　(5) We"ll go to hear the famous singer (whom/that/who) we have often talked about. 　　(6) We"ll go to hear the famous singer about whom we have often talked. 　　附：英语学习之as, which 非限定性定语 　　由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。Aswhich在句中。 　　As we know, smoking is harmful to ones health. 　　The sun heats the earth, which is very important to us. 　　典型例题 　　1)Alice received an invitation from her boss, ___came as a surprise. 　　A. it B. that C. whichD. he 　　答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。 　　2)The weather turned out to be very good, ___ was more than we could expect. 　　A. what B. which C. that D. it 　　答案B。which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。 　　3)It rained hard yesterday, ____ prevented me from going to the park.. 　　A. that B. whichC. as D. it 　　答案B. 　　as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点： 　　as 引导的定语从句可置于句首，而which不可。 　　拓展 　　1、A shop should keep a stock of those goods which sell best. 　　商店应存有最畅销的`货物。 　　2、This is the family which is planning to move to the city 　　这是要搬进城里的一家。 　　3、This is a reason which we must not forget. 　　这是我们不能忘记的一个原因。 　　4、When deep in thought, which he often was, he would forget all around him. 　　他常常陷入沉思，这时他就会忘掉周围的一切。 　　5、He bought a book, which was written by LuXun, and which he decided to give to his friend. 　　他买了本鲁迅写的书，他决定送给朋友。

which作代词使用的时候意思是：“ 哪一个，哪一些；那些”，作限定词使用的时候意思是：“ 哪一个，哪一些；……的那些；，作形容词使用的时候意思是：“哪一个，哪一些；无论哪个。 因为which这个单词的用法比较多，经常会令初学者感到比较烦恼，他们往往不能够正确使用which这个英文单词，下面让我们一起去了解which这个英文单词的正确用法吧。 详细内容 01 单词发音： 英[wu026atu0283]美[wu026atu0283] 。 02 which boy 哪个男孩； which was 定语从句 ; 省略了 ; 定于从句 ; 哪一个是； which place 哪一个地方 ; 哪个地方 ; 正在翻译。 03 Which company 选公司 ; 该公司 ; 哪个公司 ; 哪间公司； Which language 哪种语言 ; 哪一种语言 ; 其中语文； Which hand 哪只手。 04 Which pillow 什么枕头好； Which song 哪首歌 ; 哪首歌曲 ; 这首歌； Which subject 哪一门课 ; 哪门科目 。 05 You love that but I love which. 你喜欢这个，而我喜欢这个。 Which do you prefer, this or that? 你更喜欢哪个，这个还是那个?

哪一个，哪一些。

which的意思有以下几个：1、作代词时意为“ 哪一个，哪一些；（指明事物）……的那个，……的那些；（进一步提供有关某事物的信息）那个，那些”。2、作限定词时意为“ 哪一个，哪一些；（指明事物）……的那个，……的那些；（进一步提供有关某事物的信息）那个，那些”。3、作形容词时意为“哪一个，哪一些；无论哪个；（进一步提供有关某事物的信息）那个，那些”。基本用法：1、which用作疑问代词时，在特殊疑问句中用作宾语或主语。2、which用作关系代词，可引导限制性定语从句或非限制性定语从句。3、引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that，有时还可引导不定式短语从句。4、which是关系代词用作主语或宾语等。例句Which is my seat?哪个座位是我的?He also had a gun with which to defend himself.他还有一把自卫用的枪。

哪一个，，，，

关系代词which引导的定语从句，指物，在从句中可以作主语、宾语等。多数情况下，可与that互换。但是要注意当从句中，介词提前只能用which，而且，在非限制性定语从句中，which引导的句子单独翻译为一句话。

that与which两者都可指物，常可互换。其区别主要在于： 1. 引导非限制性定语从句时，通常要用which。如：She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请，这是她意想不到的。 2. 直接放在介词后作宾语时，通常要用which。如：The tool with which he is working is called a hammer. 他干活用的那个工具叫做锤子。 3. much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that。如：There was little that the enemy could do but surrender. 敌人无法,只有投降了。All [Everything] that can be done must be done. 凡能that can be done must be done. 4. 当先行词有the very, the only, the same 等修饰时，通常用that。如：This is the only example that I know. 我知道的例子只有这一个。Those are the very words that he used. 那是他的原话。 5. 当先行词有形容词最高级或序数词(包括last, next等)等修饰时，通常用that。如：。如：This is the best dictionary that I"ve ever used. 这是我用过的最好的词典。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。 6. 当关系代词在定语从句中用作表语时，通常用that。如：China is not the country (that) it was. 中国已不是过去的中国了。 7. 当先行词是一个既指人又指物的并列词组时，通常用that。如：They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。他们谈论了使他们印象最深的人和事。 8. 当要避免重复时。如：Which is the course that we are to take? 我们选哪门课程？

which的用法四种句型如下：1.which 哪个、哪一个which 用作疑问形容词时，表达选项数目固定或是有限的选项。例：Which time suits you better, 11:30 or one o"clock?哪个时间你更方便——11点半还是1点？例：Which is mine? The smaller one?哪个是我的？小一点的这个？例：Which of these jackets do you prefer?这几件夹克你比较喜欢哪件？2.which 用作关系代名词(接在逗号后面)which 当成关系代名词使用时，用于为前面的从句补充额外资讯，通常用于逗号之后。若which接在逗号后面，which指的是逗号前面所描述的整个事件。例：He showed me round the town, which was very kind of him.他带我参观了这个城镇，他真是太好了。例：She invited us to dinner, which was very kind of her.她邀请我们吃晚饭，她人真客气。3.which 用作关系代名词(前面无逗号)若which前面无逗号，则which指的是前面提到的事物。例：The museum which we visited yesterday is the biggest in the city.我们昨天拜访的博物馆是这城市里最大间的。例：It"s a disease which affects mainly older people.这疾病主要感染的是老人。4.which 的限定用法与非限定用法which当作关系代名词时，要特别注意限定用法与非限定用法。例：Tom has a cat which can sleep all day.汤姆有一只可以睡整天的猫。说明：which前面没逗号，所以which指的是”猫”，表示汤姆可能有很多猫，而这里指的是整天在睡觉的那只猫。这是限定用法。例：Tom has a cat, which can sleep all day.汤姆有一只猫，可以睡整天。说明：which前面有逗号，所以which指的是“汤姆有一只猫”，表示汤姆应该只有这只猫，而这只猫可以睡整天。这是非限定用法。

一般是定语从句

　 　定语从句which意思 　　which是定语从句的关系代词之一。GMAT语法考试限定，which有且仅有两种用法。 　　一，which前面有逗号，逗号前面是个名词，which就近指代那个名词。 　　(1) Tankfield emailed Pea some photos, which did not cheer Pea up. 　　which就近指代photos，定语从句中谓语动词did not cheer (Pea up)的发出者即从句主语即先行词photos，是photos没让豌豆家属高兴起来。 　　(2) Tankfield emailed Pea some photos, which Pea did not find interesting. 　　which就近指代photos，photos是定语从句中的宾语，把定语从句还原成一个完整句就是Pea did not find the photos interesting. 　　可以看到，上面两个句子都可以以that为关系代词改写，即 　　(1)" Tankfield emailed Pea some photos that did not cheer Pea up. 　　(2)" Tankfield emailed Pea some photos that Pea did not find interesting. 　　改写与原版区别在哪儿?就在一个逗号。which前面是名词，名词和which之间没逗号的，在GMAT语法里算错。 　　二，which前面是介词，介词前面是名词，which就近指代介词前的那个名词，名词和介词之间有无逗号均可。 　　Tankfield once lent Pea a book from which Pea glimpsed the basics of genes. 　　这个句子可以“拆”成如下两句：(每个定语从句都可以拆成两句，以先行词为拆分点) 　　Tankfield once lent Pea a book. Pea glimpsed the basics of genes from the book. 　　先行词实际上是定语从句中介词的宾语，这时，需要把介词提前，避免如下表达： 　　Tankfield once lent Pea a book, which Pea glimpsed the basics of genes from. (XXX) 　　Tankfield once lent Pea a book that Pea glimpsed the basics of genes from. (XXX) 　　 以 下几种只能使用which的情况 　　1. 在“介词+关系代词”结构中，关系代词必须用which。 　　如： The house in which we live is very large. 我们住的房子非常大。 　　This is the reference book of which the teacher is speaking. 这就是老师正在谈及的那本参考书。 　　注意： 如果介词不放在修饰事物的限定性定语从句的句首， which就可换为that， 例如： This is the question which/that we"ve had so much discussion about. =This is the question about which we"ve had so much discussion. 这就是我们已经多次讨论过的`问题。 　　2. 先行词为“those+表事物的复数名词”时， 关系代词通常只用which而不用that。 　　如：you should grasp well those skills which may be used in the future work. 　　最后，记得这个特殊情况吧：当先行词是表示原因或方式的名词时，可以用that引导定语从句，相当于介词+which，that可以省略。 　　如： She likes the child for the very reason that (=for which) she loves his father. 她喜欢那个孩子因为她爱着孩子的父亲。 　　He didn"t like the way that (=in which) she speaks to his mother. 他不喜欢她对他的母亲那样说话。 　　Imagine the speed that (=at which) he drives the car. 很难想象，他开车开得那么快。 　　The reason (that /for which /why) he came here was to ask for our help.他来这里的原因是寻求我们的帮助。 　　 高中英语定语从句学习方法 　　方法1、要注意关系代词的选用。首先记住几个大原则，譬如whothat引导人的从句，thatwhich引导物的从句whose表示所属关系。其次还要注意在某些场合下关系代词的固定使用，譬如先行词中有人有物要用that，这些情况等等。值得一提的是，what无论如何不能引导定语从句。 　　方法2、要注意从句中动词的类别。这主要是说看看这个动词是及物还是不及物。在不及物动词的情况下，要记住带上固有的介词。还要注意这个介词放置的位置，可以提前到关系代词前，也可以紧跟在动词之后。这种情况是考试最爱考的，其中涉及到动词与介词的固定搭配，句子理解与分析，是热点难点。 　　方法3、在熟练掌握定语从句的情况时，要注意省略关系代词和使用分词结构来代替从句。

what可以是感吧词,形容词,副词,名词,代词; which 只能是形容词和代词 What subject do you like?你喜欢什么事物?什么样的,为形容词; Which subject do you like?你喜欢哪一种的事物?哪个(种)的,也为形容词. 只有相同词性才可以替换.which 和 that在定语从句中使用. 分别可作,主,宾. what在名词性从句中使用. 可作主,病.

　　which的用法在英语学习中是比较重要的一个知识点，重要就说明必须要掌握。接下来我在这里给大家带来which的用法，我们一起来看看吧! 　　which的用法 　　1、在后置的非限制性定语从句中代替上文出现的事物或情况(单数或复数)。 　　2、在问句中作为疑问代词，在名词从句中作为连接代词用，其含义为“哪个、哪些”。 　　3、如果非限制性定语从句的先行词不是指主句内容，而是指具体的人、时间、地点，则不用which。 　　一、关系代词that 和which 在定语从句中作主语和宾语，放在先行词和定语从句之间，起联系作用。指物时，一般情况下可互换。如： Here is the pen that/which you lost yesterday.(that/which 指物作宾语) A plane is a machine that/which can fly.(that/which 指物，作主语) He is the most careful boy that I know.(that 指人,作宾语) The man that works in this room is a chemist.(that 指人,作主语) 　　二、that,which 在从句中作主语时，不能省略。作宾语时在口语中和非正式问题中经常省略。如上例1 和中的that,which 都可省略。 　　三、关系代词在主语从句中作主语时，从句的谓语动词的人称和数须和先行词一致。 Wheat is a plant that/which is grown in the north of China. 　　四、在定语从句中，关系代词that 和which 指物时，一般没有区别，但下列几种情况中不能互换： 　　只能用that 的情况： 　　a)先行词为 all,everything,nothing,anything,little 等不定代词时(something 后也可用which)： Is there anything (that) I can do for you in town? Thatu2019s all (that) I know. 　　b) 先行词被序数词所修饰时： The first thing (that) we should do is to work out a plan. 　　c) 先行词被形容词最高级所修饰时： This is one of the most exciting football games (that) I have ever seen. The nanjing yangtse river bridge is the longest bridge (that) they have ever seen. 　　d) 先行词 被only,very,no,any,same,little,one of 等词所修饰时： This is the only thing (that) we can do now. He gave me the same pen (that) he borrowed from me. Do you have any books that were written by Lu Xun? This is the very book (that) I want to read. 　　e) 当先行词中既有人又有物时： The man and the car (that) you want to see are all here. 你相见的人和车都在这里。 　　f) that 可指人，which 则不能： Who is the man that is reading the newspaper over there? 　　g) 在 “the time when”等结构和某些时间状语中，when 常被that 代替，而且that 往往省略： I may leave here any time I want to. During the time I was there I visited him twice. 　　h)way 后面可根由that 引导的定语从句，但that 一般都省略： That was the way she looked after us. 　　在下列情况中，只能用which: 　　a) 放在介词后面做介词宾语时： This is the question about which weu2019ve had so much discussion. 但是，如把介词放在从句的后部，这时which 就可换为that 并常省略。如上例可改为： This is the question (that) weu2019ve had so much discussion about. 　　b) 在非限制性定语从句，无论指物指人，都不能用that。指物时，只能用which 和其他关系代词。如： All the books there,which have beautiful pictures in them,were written by him. 　　which的相关解释 　　pron.哪一个; 哪一些; 哪个; 那，指前面提到的事物 　　adj.哪一个; 哪一些; 　　which与that的用法区别 　　两者都可指物，常可互换。其区别主要在于： 　　1. 引导非限制性定语从句时，通常要用which： 　　The current, which is very rapid, makes the river dangerous. 水流湍急，使这条河很危险。 　　He has to work on Sundays, which he doesnu2019t like. 他得在星期天工作，他是不喜欢这样的。 　　The London team, which played so well last season, has done badly this season. 伦敦队上一个季度打得很好，这个季度却打得很差。 　　2. 直接放在介词后作宾语时，通常要用which： 　　She may be late, in which case we ought to wait for her. 她可能晚到，那样我们就要等等她。 　　The documents for which they were searching have been recovered. 他们找寻的文件已找到了。 　　This morning some port wine came, for which I have to thank you. 今天早上送来一些波尔图葡萄酒，为此我得向你道谢。 　　注：有时“介词+which”引导的定语从句可以转换成“介词+which+不定式”结构： 　　He had only the long nights in which he could study. =He had only the long nights in which to study. 他只有漫漫长夜可用来学习。 　　He had a couple of revolvers with which he could defend himself.= He had a couple of revolvers with which to defend himself. 他只有一两把手用来自卫。 　　3. 当先行词是下列不定代词或被它们修饰时much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that： 　　All that she lacked was training. 她缺的只是训练。 　　Have you everything that you need? 你需要的东西都有了吗? 　　The sleeping manu2019s subconscious mind retained everything that was said around him. 这位酣睡的人头脑的下意识能记住他周围的人说的话。 　　She would never do anything that was not approved of by her parents. 她父母不赞同的事她绝不会做。 　　4. 当先行词有the very, the only, the same 等修饰时，通常用that： 　　This is the only example that I know. 我知道的例子只有这一个。 　　Those are the very words that he used. 那是他的原话。 　　5. 当先行词有形容词最高级或序数词(包括last, next等)等修饰时，通常用that： 　　This is the best dictionary that Iu2019ve ever used. 这是我用过的最好的词典。 　　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。 　　6. 当关系代词在定语从句中用作表语时，通常用that： 　　China is not the country (that) it was. 中国已不数去的中国了。 　　7. 当先行词是一个既指人又指物的并列词组时，通常用that： 　　They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。 　　8. 当要避免重复时： 　　Which is the course that we are to take? 我们选哪门课程? 　　which的例句 　　1.He lived on an invalidity pension which came as a weekly giro. 　　他靠每周领取的作为病残养老金的直接转账救济支票过日子。 　　2.Politicians want a lap-dog press which will uncritically report their propaganda. 　　政客们想要的是不问是非、甘为他们搞宣传的哈巴狗一样的新闻媒体。 　　3.We were in the same college, which was male-only at that time. 　　我们那时在同一所学院，当时只招男生。

可以翻译成“在哪里”，in which一般是在定语从句中，which是引导词。相当于where。例如 I know a shop in which you can go purchase. 我知道一个你可以买东西的商店。which　基本词汇　英 [wu026atu0283] 　 　 美 [wu026atu0283] 　 　adj. 哪一个；哪一些pron. 哪一个；哪些Which book have you read?哪一本书你读过了？Here are the designs. Which ones do you prefer?这就是那些图样。你喜欢哪一些?which的用法：which用作疑问代词时，在特殊疑问句中用作宾语或主语。which用作关系代词，可引导限制性定语从句或非限制性定语从句，引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that，有时还可引导不定式短语从句。

where 是副词 前面不能有 介词 which 前面可以加上介词 有时候 加上介词的 which 相当于where

"Which"和"where"都是关系词，但它们的用法有所不同。"Which"通常用于引导一个定语从句，用来描述或限定先行词的性质或特征。例如：The book, which I read last week, was very interesting.（我上周读的那本书非常有趣。）The car, which is parked outside, belongs to my neighbor.（停在外面的那辆车是我邻居的。）"Where"通常用于引导一个地点状语从句，用来描述或限定先行词所在的地点。例如：I went to the park where we used to play as kids.（我去了我们小时候玩的那个公园。）The restaurant where we had dinner last night was very expensive.（我们昨晚吃饭的那家餐厅非常贵。）总之，"which"用于描述或限定先行词的性质或特征，而"where"用于描述或限定先行词所在的地点。
