定语从句的关系代词
定语从句的关系代词在复合句中修饰某个名词或代词的从句叫做定语从句。
学习定语从句，引导定语从句的关系代词有who, whom, whose(一般指人);which(一般指物); that(指人或物)等。
在句中充当主语、宾语、表语或定语。
如：1. This is the teacher who / that teaches us English. 这就是教我们英语的老师。
(关系代词who / that 作主语。
)2. Do you understand the sentence which / that I have just explained to you? 你们懂不懂我刚才给你们讲的那个句子? (关系代词which / that 作have explained 的宾语。
)3. China is no longer the country that she used to be. 中国不再是过去那样的国家了。
(关系代词that 作be的表语。
)4. Do you know the student whose composition is the best in our school? 你认识那个在我们学校作文最好的学生吗? (关系代词whose作composition的定语。
)关系代词引导定语从句要注意下列几个问题：一、关系代词与先行词。
关系代词所修饰的(或指代的)词叫做先行词;先行词如果是“物”，则关系代词用which或that; 先行词如果是“人”，则关系代词用who或that; 也就是说，that 既可用来修饰“人”也可用来修饰“物”。
如：1. This is the newspaper which / that I am looking for.[分析]定语从句的先行词为news-paper, 故关系代词可以用which或that。
2. Mr. Li is the teacher who/that teaches us English.[分析]定语从句的先行词为teacher, 故关系代词可以用who或that。
非常详细的定语从句,状语从句,名词从句的讲解……that,which,where,who,等
定语从句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。
