1、高考资源网（） 您身边的高考专家考点9 定语从句1.主要考查的知识点：(1)关系词的选用(2)关系词前加介词等的用法(3)定语从句的时态(4)非限制性定语从句的用法2.复习重点：(1)关系代词和关系副词的用法区别。(2)掌握只能用that引导定语从句的情形。(3)掌握介词加关系代词的用法。(4)掌握as和which引导非限制性定语从句的用法。3.应对方法：解题时，首先要确定先行词，根据先行词在从句中所作的句子成分来判断该用关系代词还是副词，并且确定具体用哪个关系词。如果从句中谓语动词为不及物动词，应考虑关系代词前该不该加介词。定义1. 定义：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所

2、修饰的先行词后面。2. 先行词：被定语从句修饰的名词或代词称为先行词。3. 关系词：引导定语从句的关联词称为关系词。关系词有关系代词和关系副词。关系代词：who, whom, whose, which, that, as等；关系副词：where, when, why等。关系词常有三个作用：引导定语从句；代替先行词；在定语从句中充当一个成分。如： Harry Potter is the most interesting novel that I have read.分析：that I have read是定语从句；novel是先行词；that 是关系代词，代替先行词novel，在从句中作have

3、 read的宾语。 关系词指代人或物定语从句中充当的成分关系代词that人或物主语、宾语、表语which物或主句内容主语、宾语或定语who人主语或宾语whom人宾语whose人或物定语as人或物或主句内容主语或宾语关系副词when时间状语where地点状语why原因状语4. 限制性定语从句和非限制性定语从句 限制性定语从句形式上不用逗号和主句隔开，是先行词不可缺少的部分，去掉它主句意思往往不明确，翻译成先行词的定语，“的”。 非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，通常翻译成主句的并列句。关系代词that和关系副词why不能引导非限制性定语从

11、句中作宾语并且前面无介词时，关系代词可省略，其他情况不可省，如：(1)。规则2：定语从句中的主谓一致问题(1)关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致，如：(2)。(2) one of 复数名词 关系代词 复数动词；而the only one of 复数名词 关系代词 单数动词，如：(3)。(3)非限制性定语从句中，由关系代词as或which代替整个主句时，从句谓语动词要用第三人称单数，如：(4)。(4)关系代词和谓语动词之间有插入语时，谓语动词单复数要看关系代词的指代，如：(5)。规则3：指物时，定语从句中的关系代词只能用that的情况：(1)当先行词为ever

12、ything, anything, nothing, the one, none, all, much, few, any, little等不定代词时，如：(6)。(2)当先行词被the only, the very, all, much, few, any, little, no修饰时，如：(7)。(3)当先行词是序数词、形容词最高级或者先行词被序数词、形容词最高级修饰时，如：(8)。(4)先行词既有人又有物时，如：(9)。(5)当主句的主语是疑问词who或which时，为避免重复要用that，如：(10)。(6)有两个定语从句时，其中一个关系代词已用which，另一个则用that，如：(1

13、1)。(7)当先行词在主句中作表语，而关系代词也在从句中作表语时，只用that，如：(12)。规则4：指物时，定语从句中的关系代词只能用 which的情况：(1)在引导非限制性定语从句时，如：(13)。(2)介词后，如：(14)。(3)有两个定语从句时，其中一个关系代词已用that，另一个宜用which。规则5：指人时，定语从句中的关系代词只能用who的情况：(1)当先行词是anyone, those时，如：(15)。 (2)有两个定语从句时，其中一个关系代词已用that，另一个宜用who。规则6：whose可以指代人或物，在定语从句中作定语， 后跟名词。指物时，whose名词名词 of wh

14、ich of which 名词，如：(16)。规则7：关系代词as和which 在非限制性定语从句中，as和which可代替整个主句，相当于and this或and that。二者的区别主要在于：(1) as引导的非限制性定语从句既可以在主句前，也可以在主句后，有时还可以插入句中，常带有“正如，正像”的意思。而which引导的非限制性定语从句只能放在主句之后，翻译成“这”，如：(17)。(2) 主句中出现the same, as, such, so修饰先行词，需选择as做关系代词在定语从句中作主语或宾语，如：(18)。【注意】当先行词由the same修饰时，有时也用that引导定语从句，但是

15、和由as所引导的意思不同：that表示同一个，as表示同一类。(3)在以下结构中，一般也用as: as (it) appears, as (it) seems likely, as (it) often happens, as (it) was pointed out/said/reported/announced, as (it) was said earlier, as I remember (it), as is wellknown, as is known to all, as anybody can see等，如：(19)。规则8：“介词关系代词”引导的定语从句“介词关系代词”引导的

16、定语从句，关系代词指人时用whom，指物时用which。(1) 某些带有介词的动词短语，介词可以提至关系代词之前，但是在一些固定搭配的短语动词中，由于动词和介词不可以分割，因此不能将介词置于关系代词之前，如take care of, look for, look after, care for等，如：(20)。(2)“介词关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词，有时数词或代词也可以放在“介词关系代词”之后，如：(21)。(3)介词which / whomto do结构。这种结构可以改为：介词whic

17、h / whom定语从句，如：(22)。(4)在非限制性定语从句中，which可作定语，指先行词(短语或句子)所表示的信息，形成“介词which 名词”结构，相当于and in/at/during this/that名词，如：(23)。2. 关系副词的使用(1) I still remember the day when / on which I first came to the school.(2) The house where / in which I lived ten years ago has been pulled down.(3) I dont know the reason

19、点状语，where表示地点的介词(in / at / on / under)which，如：(2)。规则3：why指原因，在定语从句中作原因状语， why表示原因的介词(for)which，如：(3)。规则4：以the way为先行词的定语从句通常由in which或that引导，而且通常可以省略，如：(4)。【注意】 The way (which / that) he explained to us was quite simple.(which / that在从句中充当宾语成分) 规则5：有时为了表达更清楚，可以在关系副词where / when前加上介词to, from等，如：(5)。【

20、注意】 一些特殊的先行词如situation, point, case, activity，scene及period, festival, occasion等要注意具体情况具体分析，作主语、宾语和表语时，用关系代词that/which；作状语时，用关系副词where/when或“介词which”。There is one point (that/which) we must insist on. 有一个观点我们必须坚持。(定语从句可还原为：we must insist on the point, 所以先行词point在定语从句中作宾语，故用that/which或省略。) Were just t

21、rying to reach a point where both sides will sit down together and talk. 我们正努力做到能让双方坐下来对话。 (定语从句可还原为：at a point both sides will sit down together and talk, 故先行词point在定语从句中作状语，所以关系词用where/at which。)3. 关系代词/关系副词的选择 用适当的连接词填空(1) I will remember the days that we spent together. (2) June 7 is the day whe

22、n we begin to take the college entrance examination. (3) This is the place that we visited the day before yesterday. (4) This is the place where he worked for ten years. 规则1：用还原法：将先行词放入定语从句中，找到它的原有位置，判断它作什么成分以及判断先行词指人还是指物。规则2：一般说来，作主语、宾语或表语时，用关系代词；作状语时，用关系副词或介词which；作定语时，用whose。4. 定语从句和其他句型之间的区别用适当的

(4) He said nothing, which made me angry.(5) He said nothing, and that made me angry.(6) As is known to all, the moon travels around the earth. 4. 定语从句和其他句型之间的

(13) It was in this small village that we got to know each other. 规则1：区别suchas / soas引导的定语从句和such/sothat引导的结果状语从句 如果从句缺少主语或宾语就是定语从句，连接词用as，如：(2)；如果从句的结构完整，就是结果状

26、语从句，连接词用that，如：(1)。规则2：区别非限制性定语从句与并列句 定语从句与主句之间用关系词连接，如：(4)；并列句之间用并列连词，如：(5)。规则3：定语从句与名词性从句 定语从句中，关系代词在从句中作主语、宾语、表语，如：(6)；而名词性从句中的连词that在从句中不作任何成分，如：(7)；疑问代词what及疑问副词how可连接名词性从句，但不能引导定语从句，如：(8)、(9)。规则4：定语从句与地点状语从句 关系副词引导定语从句时，其前面必须有时间、地点、原因等先行词，如：(10)；而疑问副词连接状语从句时，其前面没有，如：(11)。规则5：定语从句与强调句、状语从句 that在定语从句中作主语、宾语、表语，如：(12)；而强调句型中不作任何成分，但不能省，如：(13)；在结果状语从句中that也只起连接作用，在从句中不充当任何成分。- 7 - 版权所有高考资源网
