考点1 5组易混关系代词的用法辨析 ★★★★★
1. 只用that不用which的情况:
(1)先行词是all, much, little, something, everything, anything, nothing, none等不定代词时。

*Is this the house in which Shakespeare was born
(2)引导非限制性定语从句时。

The exact year_______Angela and her family spent together in China was 2008.
解题关键: 本题先行词为year, 考生首先会想到when。但当先行词为时间、地点名词时, 用关系副词还是关系代词取决于该词在定语从句中充当什么句子成分。本题定语从句中的谓语动词spent为及物动词, 故从句中缺少宾语, 关系词代替先行词作其宾语。
答案判定: which/that

考点2 关系代词who, whom, whose ★★★★★
1. who和whom的用法。
(1)先行词为one, ones, anyone, those指代人时或表示人的名词时。
*The person I want to talk about with you is Tu Youyou, the one who won the Nobel Prize for medicine in 2015.
我想和你谈论的人是屠呦呦, 她获得了2015年诺贝尔医学奖。
(2)在There be结构中, 修饰主语的定语从句宜用关系代词who指代人。
*There’s a gentleman who wants to see you.
(3)一个句子中带有两个修饰人的定语从句, 其中一个定语从句的关系代词是that, 另一个宜用who以避免重复。
*The student that was praised at yesterday’s meeting is the monitor who is very modest and works very hard.
(4)当关系代词前面有介词时, 只能用whom, whom在定语从句中作介词的宾语时, 介词可放在后面, 也可提前构成介词+whom(先行词指人)结构。
*The settlement is home to nearly 1, 000 people, many of whom left their village homes for a better life in the city.
2. whose的用法。
whose指人或物, 作定语, 表示“……的”, 可转换为“of +关系代词”, 指人时可用of whom; 指物时可用of which。
*The prize will go to the writer whose story/of whom the story shows the most imagination.
【点津】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。例如:

汤姆是被派往国外的工程师之一。
*Tom is the only one of the engineers who has come up with the solution. 汤姆就是唯一提出解决方案的那位工程师。

考点3 关系副词when, where, why ★★★★

*The days are gone when physical strength was all you needed to make a living.
体力是你生存所需的一切手段的日子一去不复返了。
2. where的用法。
(1)先行词是“地点名词”, 定语从句可用where引导, where在从句中作状语, 也可用“介词+which”结构代替。

*The reason why/for which he didn’t attend the meeting was that he was ill. 他没出席会议的原因是他生病了。
【点津】
(1)选择关系代词或关系副词的原则: 在选择关系词时, 最重要的是分析定语从句中所缺的成分。若从句中缺主语、宾语、定语或表语, 那么必须用关系代词; 若从句中不缺主语、宾语、定语或表语, 那么必须用关系副词。
*This is the mountain village that/which I visited last year.
这就是我去年参观的山村。(关系词在从句中作宾语)
*I will never forget the day when my father returned from America. 我永远不会忘记我父亲从美国返回的那一天。(关系词在从句中作状语)
(2)当way表示方法、方式作先行词, 且后面的定语从句缺方式状语时可以用that或in which引导, 也可以省略关系词。如果后面定语从句中缺少宾语, 要用that或which引导, 也可以省略关系词。
*I don’t like the way that/in which/不填 he speaks to his mother.

考点4 介词+关系代词的6个考查点 ★★★★
1. 考查定语从句中动词与介词的搭配。
*Wind power is an ancient source of energy to which we may return in the near future.
2. 考查定语从句中形容词与介词的搭配习惯。

*I am looking for my glasses, without which I can’t watch TV clearly.

注意: the+n. +of which(whom)可与whose+n. 互换。
5. 考查表示整体与部分关系的of which/whom。
*The buses, most of which were already full, were surrounded by the angry crowd.
6. 考查表示同位关系的of which/whom。
*She brought with her three friends, none of whom I had ever met before.
【点津】选择介词的3个原则:
①根据句子意思表达的需要;
②根据从句中动词或形容词与介词的搭配习惯;
③根据先行词和介词的搭配习惯。
【辨析】定语从句与几种句式和从句的区别:
与并列句的区别 如果两个句子之间是分号, 或有and, but, so等连接词, 则这两个句子为并列句; 如果两个句子之间是逗号, 且没有上述的连接词, 则这两个句子之间就是主从关系, 须有一个引导词引导定语从句
与强调句型的区别 判断强调句型的关键在于把强调结构“It is/was. . . that/who. . . ”去掉后, 主句的意思和结构是完整的
与状语从句的区别 状语从句没有先行词, 整个从句在复合句中作时间、地点或原因等状语, 而定语从句是对先行词起修饰限定作用的
与同位语从句的区别 ①定语从句对先行词起修饰、限定作用; 而同位语从句对先行词起解释、说明作用;
②引导词that在从句中的作用不同: 在定语从句中, that既起连接作用, 又在定语从句中充当句子成分, 如主语、宾语等; 而在同位语从句中, that只起连接作用, 不充当句子成分
(1)The news(that)they told me made me excited. (定语从句)
(2)The news that our team won the match made me excited. (同位语从句)
【例析】完成句子

他写了很多儿童书籍, 差不多一半发表于20世纪90年代。
解题关键: 由逗号可知前后句关系, 后句为非限制性定语从句, 修饰先行词books。根据汉语“一半”“发表”可填出答案, 注意关系代词的选取及定语从句中的语态。
答案判定: half of which were published
