1、 2020 年高考语法考点讲解与真题分析 07 定语从句（二）考点二 “介词+关系代词”引导定语从句 “介词+关系代词”在从句中作定语或状语。能用于这一结构的关系代词只有 whom,which,whose 三个，whom,which 作宾语，whose 作定语。这一结构的中介词由两个方面来确定：与先行词的搭配；与从句谓语动词的搭配。1.We choose this hotel because the price for a night here is down to$20,half of _ it used to charge.（2017 江苏）A.that B.which C.what D.

2、how【答案】B 【解析】这里是“介词+关系代词”引导的定语从句，排除 C、D；“介词+关系代词”中，关系代词不能用 that，故选 B。2.In 1963 the UN set up the World Food Programme,one of _ purposes is to relieve worldwide starvation.（2017江苏）A.which B.its C.whose D.whom 【答案】C 【解析】这里是“介词+关系代词”引导的定语从句，关系词在从句中作定语，修饰 purpose，故用关系代词 whose。3.Many young people,most _

3、were well-educated,headed for remote regions to chase their dreams.（2016 江苏）A.of which B.of them C.of whom D.of those【答案】C【解析】这里是“介词+关系代词”引导的定语从句，排除 B、D；关系代词指代 people，故用关系代词 whom。4.Creating an atmosphere _ employees feel part of a team is a big challenge.(2015 浙江)A.as B.whose C.in which D.at which【答

4、案】C【解析】这是一个含有定语从句的复合句，关系词在从句中作状语，只能用“介词+关系代词”，先行词是 atmosphere，表示“在氛围中”，应用介词 in。5.Some experts think reading is the fundamental skill upon _ school education depends.(2015 安徽)A.it B.that C.whose D.which【答案】D【解析】这里是“介词+关系代词”引导的定语从句，关系代词指作宾语，故用 which。注意：which 引导定语从句在从句中一般不作定语，但在“介词+关系代词”引导的定语从句中，which

5、可替代指示代词作定语。例如：He may win the competition,_he is likely to get into the national team.(2013 辽宁)A.in which case B.in that case C.in what case D.in whose case【答案】A【解析】这里是“介词+关系代词”引导的定语从句，关系代词指替代指示代词 that 在从句中作定语。定语从句写成一个完整的句子是：In that case,he is likely to get into the national team.考点三 关系代词 as 引导定语从句 关

6、系代词 as 可以引导限制性或非限制性定语从句，并在从句中作主语，宾语或表语。as 常用来引导非限制性定语从句，as 指代整个主句，表示“正如”；as 引导限制性定语从句只有两种情况，一是先行词前有 such 修饰，二是先行词前有 the same 修饰。1.The number of smokers,_ is reported,has dropped by 17 percent in just one year.(2015 江苏)A.it B.which C.what D.as 【答案】D【解析】解析：这是一个含有一个非限制性定语从句的复合句，关系词在从句中作主语，且表示“正如”，故用 as

7、。2.There is no simple answer,_ is often the case in science.(2013 山东)A.as B.that C.when D.where 【答案】A【解析】这是一个含有一个非限制性定语从句的复合句，关系词指代整个主句在从句中作主语，故用 as。3.lot of language learning,has been discovered,is happening in the first year of life,so parents should talk much to their children during that period.

8、(2012 安徽)A.as B.it C.which D.this【答案】A【解析】这是一个含有一个非限制性定语从句的复合句，关系词在从句中作主语，且表示“正如”，故用 as。4.The air quality in the city,_ is shown in the report,has improved over the past two months.(2012 福建)A.that B.it C.as D.what【答案】C【解析】这是一个含有一个非限制性定语从句的复合句，关系词在从句中作主语，且表示“正如”，故用 as。注意：as 与 which 引导非限制性定语从句的区别 as 与

9、 which 都可引导非限制性定语从句，其区别可从两个方面来把握。1.位置上：which 引导的非限制性定语从句只能放在主句后，而 as 引导的非限制性定语从句的位置则比较灵活，可以放在主句前，也可以放在主句后，还可以把主句隔开。2.意义上：which 指代具体的一件事，而 as 意思比较模糊，一般指一个概念，常译作“正如”。例如：As a poet once pointed out,life is but a dream.正如一位诗人所说，人生如梦。Tom failed in the exam,which made his parents angry.汤姆考试没及格，这使他父母很生气。提示：

10、as 引导非限制性定语从句时常构成一些固定结构，主要有：as is known to all 众所周知 as is often the case 情况常常如此 as may be imagined 可以想象得出 as often happens 这种情况常常发生 as has been said before 如前所述 as is hoped 正如所希望的 as is natural 很自然 as is supposed 正如所料 考点四 定语从句中的主谓一致问题 关系代词在定语从句中作主语时，便涉及到主谓一致的问题。定语从句的谓语动词与其先行词在人称和数上要保持一致。因此，准确辨识先行词是解

11、决这一问题的关键。1.The publication of Great Expectations,which _ both widely reviewed and highly praised,strengthened Dickens,status as a leading novelist.（2017 江苏）A.is B.are C.was D.were【答案】D【解析】which 引导定语从句，并在从句中作主语。先行词是 The publication of Great Expectations，是单数；叙述过去的事情，应用一般过去时，故选 C。2.The factory used 65

12、percent of the raw materials,the rest of which _ saved for other purposes.(2011 安徽)A.is B.are C.was D.were 【答案】D【解析】“the rest of+复数名词”作主语，谓语动词用复数，这里 which 指代的是 the raw materials，故用复数；再由主句是一般过去时，确定从句也用过去时，故选 D。3.Barbara is easy to recognize as shes the only of the women who _ evening dress.(2010 全国)A

13、.wear B.wears C.has worn D.have worn【答案】B【解析】先行词是 the only(one)of the women，中心词是 the only(one)，所以定语从句谓语动词用单数；这里指的是她现在的穿着情况，故用一般现在时。当先行词是“one of the+复数名词”时，中心词是复数名词，定语从句谓语动词用复数。巩固练习：1.The schools themselves admit that not all children will be successful in the jobs _ they are being trained.A.in that

14、B.for that C.in which D.for which【答案】D 【解析】jobs 后是一个由“介词+关系代词”引导的定语从句，从句意思是“他们为工作 而正在进行的培训”，故介词应用 for。2._ I explained on the phone,your request will be considered at the next meeting.A.When B.After C.As D.Since【答案】C【解析】as 引导非限制性定语从句，as 替代后面的整个主句，在从句中作宾语。3.She showed the visitors around the museum,th
