限制性定语从句是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。这种从句与主句的关系十分密切，书写时不可用逗号分开。
D yu knw the girl wh just came in?你认识那个刚刚进来的女孩吗？(若把从句去掉，则不明白是哪个女孩)The ld wman，wh lives n her wn，has a cat fr cmpany.这个老妇人一个人住，养了一只猫陪伴她。(若把从句去掉，仍然知道是哪个老妇人)
一、只用that不用which的情况1．先行词是不定代词all，much，little，smething，everything，anything，nthing，nne等或者先行词被不定代词所修饰时。D yu have anything that yu want t say fr yurself?你有什么要为自己说的吗？2．先行词被序数词、形容词最高级或the nly，the very (恰恰，正好)，the last，all，n，few，little，any等修饰时。This is ne f the mst exciting ftball games that I have ever seen.这是我见过的最激动人心的足球比赛之一。This is the nly thing that we can d nw.这是我们现在唯一能做的事情。
3．先行词既有人又有物时。The scientist and his achievements that yu tld me abut are admired by us all.你告诉我的那位科学家和他所取得的成就为我们所有人所钦佩。4．当先行词在主句中作表语，而关系代词也作表语时。Shanghai is n lnger the city that it used t be.上海不再是过去的那座城市了。5．当主句的主语是疑问词wh或which时。Wh is the persn that is standing at the gate?站在门口的那个人是谁？
二、只用which不用that的情况1．引导非限制性定语从句。Helen was much kinder t her yungest sn than t the thers，which，f curse，made the thers envy him.海伦对她最小的儿子比对其他的儿子好得多，这当然使其他的儿子很嫉妒她的小儿子。 2．关系代词充当介词的宾语，且介词位于关系代词之前。This is the huse in which Lu Xun nce lived.这是鲁迅曾住过的房子。3．引导的定语从句修饰前面的整个主句，代替主句所表示的整体或部分概念。The result was nt the same as they had expected，which was rather disappinting.结果与当初预料的不一样，这令人很失望。
三、 宜用wh不宜用that的情况1．当先行词是指人的不定代词时，如：ne，nes，anyne。Anyne wh des that must be mad.谁那样做都一定是疯了。2．当先行词是I，yu，he，they等人称代词时(常用于谚语中)。He wh desn't reach the Great Wall is nt a true man.不到长城非好汉。3．当先行词为指人的thse时。Thse wh have gd manners will be highly respected.那些有礼貌的人会受到人们的高度尊重。4．在there be结构中，先行词是指人的名词时。There is a yung man wh wants t see yu.有一个年轻人想见你。
四、关系代词作介词的宾语关系代词作介词的宾语时，为了使关系代词与先行词的关系更加紧凑，可以将从句中的介词提到关系代词前，形成“介词＋关系代词”结构。该结构中的关系代词可用which，whm或whse。介词的选用(1)根据先行词与介词的搭配习惯来确定。先行词往往是表示时间、地点、原因、方式等的词，它与介词之间有一定的联系。D yu still remember the days during which we wrked tgether?你还记得我们在一起工作的那些日子吗？
(2)根据定语从句中的谓语动词或形容词确定介词。该动词或形容词常与某些介词构成固定搭配。The scial prblem abut which the tw sides are debating with each ther is a very serius ne.(debate with 就……与某人展开辩论)双方正在展开辩论的社会问题是很严重的一个问题。
关系代词作间接宾语时，用t或fr。The girl that Tm gave the dictinary t is very pretty.汤姆给她字典的那个姑娘很可爱。I knw the by whm yu bught a white hat fr.我认识你给他买白帽子那个男孩。
(3)根据句子的意思确定介词。有些句子，先行词完全一样，定语从句中谓语动词也不是固定的动词短语。这时，需要根据句子所要表达的意思选用不同的介词。Water is f great imprtance，withut which peple can nt live.水是很重要的，没有它人们就无法生存。This is the bk abut which yu have talked t me.这是你曾经给我谈起的那本书。This is the bk n the cver f which there is a map f China.这是封面上有张中国地图的那本书。
