定语从句用法
定语从句用法如下：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。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 which。3、有时as也可用作关系代词。
定语从句用法详解
定语从句用法详解 想要学好英语怎么能不知道定语从句的用法呢?下面就让我为大家详解一下吧。 在英文中，有两种定语从句：限定性定语从句与非限定性定语从句。这两种定语从句在其功能和形式方面都有明显的区别： 限定性定语从句限定性定语从句与主句的关系很紧奏，对其先行词起限定、修饰的作用。如果将其去掉，会影响句子意思的.完整性;有时甚至于引起费解、误解。例如： Rainforests are being cleared for valuable timber and other resources to speed up the economic growth of the nationsin which they are located . 为了加速他们各自所在国家的经济发展，热带雨林作为有价值的原木和其他资源正为人们所砍伐。 Ocean currents affect the climates of the lands near which they flow. 洋流影响其流经的附近地区的气候。 They explained the reason to us why they had hated us before. 他们向我们解释为什么他们不喜欢我们的原因。 非限定性定语从句非限定性定语从句在形式上就与主句很松散，它与主句之间有一个逗点"，"隔开;它对其先行词没有限定、修饰的作用，只起补充、说明的作用。有时也用它来对全句进行补充、说明。即使将其去掉，也不会影响句子意思。由于上述原因，非限定性定语从句在表达意思方面也有别于限定性定语从句。另外，非限定性定语从句在中文译文里，我们往往将其作为一个分句处理，而不把它作定语翻译。 例如：Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy . (此句中，非限定性定语从句是对先行词a sphere进行补充、说明。) 更早之前，巴比伦人曾试图绘制世界地图，但是他们把它绘制成平盘状而不是托勒密所采用的球体状。 The combination of satellites, which transmit information , computers , which store information , and television , which displays information , will change every home into an education and entertainment center . (此句中，三个非限定性定语从句分别对三个先行词：satellites ，computers和television进行补充、说明。如果去掉这三个非限定性定语从句，那么句子可简化为： The combination of satellites , computers and television will change every home into an education and entertainment center .)卫星能传输信息，计算机能储存信息，电视能显示信息，把这些手段结合起来可以使每个家庭都成为教育娱乐的中心。 The sun heats the earth , which makes it possible for plants to grow .(此句中，非限定性定语从句是对全句进行补充、说明,将全句表达的意思看成"一件事情)。太阳给予大地热，这就使植物的生长成为可能。 The old man has a son , who is in the army .(此句中，非限定性定语从句是对先行词son进行补充、说明。但本句所传达的信息是："这位老人只有一个儿子" .如果将此句改写成限定性定语从句： The old man has a son who is in the army . 那位老人有一个在部队工作的儿子。那么，限定性定语从句就要对先行词son进行限定、修饰。这样一来，句子所传达的信息就变成了："这位老人有一个儿子在部队工作，还有其他的儿子在干别的工作".)那位老人有一个儿子，他在部队工作。 限定性定语从句与非限定性定语从句的区别 a) 非限定性定语从句和主句的关系不十分密切，朗读时先行词部分一般用降调并稍做 停顿，书写的时候多半用逗号分开。 b) 非限定性定语从句能够修饰整个句子，限定性定语从句则不能。 c) 非限定性定语从句与限定性定语从句的含义不一样，限定性定语从句是确指，而非 限定性定语从句是泛指。 d) 先行词为专有名词或者具有特指对象的名词时，一般要用到非限制性定语从句。 e) 在非限定性定语从句中，现行词指人的时候，关系代词只能是who,whom，不能用 that;先行词指物的时候，关系代词只能用which, 不能用that. ;

定语从句的用法归纳总结
如下：一、定于从句：定语从句是指用一个完整的句子做定语去修饰限定前面的名词或者代词，它属于后置定语。1、限制性定语从句不用逗号与主句隔开。例：I have a sister who is a doctor.（限制性定语从句）我有一个当医生的姐姐。2、非限制性定语从句需使用逗号和主句隔开。例：I have a sister, who is a doctor.（非限制性定语从句）我有一个姐姐，她是当医生的。二、定语从句的关系词。引导定语从句的关系词分为：关系代词和关系副词。常见的关系代词有：who, that,whom, whose, which等；在从句中作主语、宾语、定语等。常见的关系副词有：where,when,why等；在从句中作状语。三、定语从句中关系代词的用法。1、当先行词是人时：关系代词who和that既可以做主语，又可以作宾语，而且作宾语时可以省略。例如：Do you know the girl who/that often comes here?（作主语）2、其中whom只作宾语。例如：The girl who/that/whom I spoke to is my daughter.（作宾语）3、当先行词是物时：关系代词which和that既可以做主语，又可以作宾语，而且作宾语时可以省略。例如：The building which/that stands near the train station is a supermarket.（作主语）4、whose既可以指人，也可以指物；that既可以指人，也可以指物。例如：The book which/that you bought for me is very interesting.（作宾语）5、whose既可以指人，也可以指物；在从句中作定语，形式为“whose+名词”表所属关系，即谁的。例如：Do you know the singer whose name is Wang feng?I live in a house whose windows face south.四、定于从句中只用which不用that的情况：（1）which引导非限制性定语从句，that则不能。He had failed in the maths exam,which made his father very angry.（2）在介词提前的定语从句中，只用which不用that。This is the place in which Lu Xun used to live.先行词本身是that时，只能用which。What’s that which flashed in the sky just now?五、关系副词引导的定语从句。1、when指时间在定语从句中作时间状语也可做连接词用。I still remember the day when I first came to the school.2、where指地点在定语从句中作地点状语。Shanghai is the city where I was born.3、why指原因在定语从句中作原因状语，用在reason后面。Please tell me the reason why you missed the plane.
