2020届高三语法专题复习一：定语从句
Ⅰ.定语从句中关系词的选定：
方法：确定先行词，并根据它在从句中所充当的成份来选择关系代词that,which,who,whom,whose 或关系副词when,where,why如：
(1)The exact year that/which Angela and her family spent together in Paris was2010.
(2)I am looking forward to the day when my son can understand my affection for him.
(3)Maria settled down in Paris in1998,where three years later,she received her doctor’s degree.
(1)Is this factory D you visited last Friday?
(2)Is this the factory A you visited last Friday?
(3)Is this factory C/B you spent your last summer holidays?
小提示：将疑问句转换为陈述句后再完成句子。
句型转变：
This is the house whose window broke last night.
=This is the house the window of which broke last night.
=This is the house of which the window broke last night.
对比填空：
(1)No drug is free from risk,of which some might be rather serious or even deadly.
(2)Last March,a nuclear disaster broke out in Japan,whose shadow was cast over policy.
(3)On hearing the adjustment of educational policies,many netizens put up posts,78%of which conveyed the message of approval.
注意：
1.当先行词为way在从句中做状语时，引导定语从句的关系词可以有三种形式：/;in which;that.
2.当先行词为time(次数)并在从句中作状语，引导定语从句的关系词用that(可省略).
3.引导定语从句的关系代词who,that,which在从句中作主语时，绝不能省略.
4.当定语从句中先行词为case,point,atmosphere,situation,scene,activity,etc且在从句中充当状语，关系副词多用where；而先行词为occasion,times（时候），period,stay,etc则多用when.
【题组训练】
1.I do n’t like the way that/in which/he treats his parents.
2.This is the second time that I have been here.
3.Young adults realize what they learnt from the book can’t handle situations that/which appear in reality.

6.There are times when we would willingly give everything we possess to save our lives.
7.We’re just trying to reach a point where both sides will sit down together and talk.
8.I have few occasions when I can stay with my wife and children.
Ⅱ.关系代词that和which的用法
1.限制性定语从句中，只用that不用which的情况：
(1)先行词为不定代词anything,something,everything,nothing,the one,all,much,little等。
①I am sure she has something(that)you can borrow.
②I’ve read all the books that are not mine.
(2）当先行词前面有the only,the very,any,few,little,no,all等词修饰时。
This is the very book that belongs to him.
(3)先行词为序数词、形容词最高级或先行词被序数词、形容词最高级所修饰时。
①When we talk about Wuxi,the first that comes into mind is Tai Lake.
②The most important thing that should be done now is how to stop him from going on.
(4）先行词既指人，又指物时。
I really miss the girl and her garden(that)I saw the other day.
(5）当先行词在主句中作表语，关系代词在从句中也作表语时。
Shanghai is no longer the city that it used to be.
(6)当主句的主语为who或which时或有两个定语从句其中一个用which另一个则用that。
①Who is the boy that won the gold medal?
②They secretly built up a small factory,which produced things that could cause pollution.
2.定语从句中不用that的情况：
(1)that不能引导非限定性定语从句。
(2)介词提前时，关系代词不用that。
【题组训练】
(1)They secretly built up a small factory which produced things that could cause pollution.
(2)The birds tried to find as many materials as possible with which to build their nests.

A.that
B.when
C.what
D.which
III.关系代词as和which在非限制性定语从句的运用：
1.as引导的定语从句可置于主句前或后；而which引导的定语从句只能放在主句后。
2.as引导非限制性定语从句时，常含有“正如”的含义，而which没有。
(1)The weather turned out to be very good,which was more than we had expected.
(2)Whenever I met her,which was fairly often,she greeted me with a smile.
(3)As he puts it,everything is possible if we keep on.如他所言，只要我们坚持下去，一切皆有可能。
3.as多用于习惯用语，常接被动态如：as is known to all,as has been said before,as is reported,as is expected,as is often the case,as was pointed out等。
He shouts when he gets angry,as is often the case.他生气时就大叫，这是常有的情形。
注意：
◆几种句型的转换
As is known to everybody,the moon travels round the earth.
=The moon travels round the earth,as/which is known to everybody.
=It is known to everybody that the moon travels round the earth.
=What is known to everybody is that the moon travels round the earth.
◆当先行词被the same所修饰时，关系词既可以用as（表同一类型）；也可以用that（表同一事物）。
1.She wants to buy the same bike as my classmate lent me yesterday.
2.This is the same pen that I lost yesterday.
◆当先行词被such,so修饰时，关系词应当用as；
而so...;引导结果状语从句（如此......以致......）
1.The Disneyland is such an interesting place that every child wishes to go there one day.
2.It is such a risky situation as he almost couldn’t control.What a narrow escape!
3.We have found such materials as are used in their factory.
小提示：如果从句中缺主、宾、表就用as，否则用that。
IV.介词+关系代词(介词+which/whom)
定语从句中介词提前时，关系代词只能用whom(指人)或which(指物)且不能省略。
