定语从句
Tip 1 who、whom、whose引导的定语从句
一、 关系代词引导的定语从句
1.who或whom均可指代人,但who在从句中可作主语也可作宾语,whom在从句中只作宾语,两者在引导限制性定语从句时常可用that替换。作主语时,who/that不可省略;作宾语时,whom/who/that可以省略。(2020·全国Ⅰ)Do not follow the people who make you feel not-good-enough. 不要跟随让你感觉不够好的人。I've become good friends with several of the students in my school (who/whom/that) I met in the English speech contest last year. 我与几个在去年英语演讲比赛中结识的学生成了好朋友。
(2021·全国甲)Even worse, the study found that girls act on that belief. Around age six they start to avoid activities said to be for children ①    are “really, really smart”.更糟糕的是,研究发现女孩们是按照这个信念行事的。六岁左右,她们开始避免那些据说是“非常非常聪明”的孩子参加的活动。
2.whose表示所属关系,一般指人,也可指物,在从句中作定语。指物时相当于of which,指人时相当于of whom。I had an unexpected teaching assistant in class ②     creativity would infect other students.我在班上有一位意想不到的助教,他的创造力会感染其他学生。

Tip 2 that、which引导的定语从句
1.which指物,常在从句中作主语、宾语,作宾语时可以省略。that指人或物均可,常在从句中作主语、宾语、表语,作宾语时可以省略。Last month, an English festival was held in our school, and our class performed a song which/that you taught us at the festival.上个月,我们学校举办了一场英语节,我们班表演了你在节日上教我们的一首歌。She showed the visitors around the museum that/which had been constructed three years before. 她带着游客参观了那座三年前建造的博物馆。
2.限制性定语从句中,关系代词只用that不用which的情况:(1)先行词为不定代词anything、nothing、something、everything、all、some、none、little、few、the one等时。I refuse to accept the blame for something ①     was someone else's fault. 我拒绝接受因别人的错误而对我进行的指责。 (2)先行词是形容词最高级或序数词,或先行词前有形容词最高级或序数词修饰时。The first place ②     they visited in Guilin was Elephant Trunk Hill. 他们在桂林参观的第一个地方是象鼻山。

Tip3 as引导的定语从句
1.as可以引导限制性定语从句,常用于“such/the same+先行词+as...”结构中。Such machines ①     are used in our workshop are made in China. 像在我们车间使用的这种机器是中国制造的。 2.as也可以引导非限制性定语从句,补充说明整个句子,可放在主句之前、之中或之后。常用的类似的插入语有as the saying goes、as is said above、as is mentioned above、as often happens、as is often the case、as is reported in the newspaper等。(2020·全国Ⅲ)The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines.众所周知,巴瑶人在印度尼西亚、马来西亚和菲律宾有数十万人。“You can't judge a book by its cover,”②     the old saying goes. 俗话说:“人不可貌相。”

二 、关系副词引导的定语从句
Tip 1 where引导的定语从句
where表示地点,在定语从句中作地点状语,相当于“介词+which”。(2021·新高考Ⅰ)Though it is the only unnatural thing on your way up the mountain, still it highlights the whole adventure and offers a place where you can sit down to rest your aching legs.虽然在上山的路上,这是唯一不自然的东西,但它仍然突出了整个冒险,并且提供了一个地方,让你可以坐下来使你酸痛的双腿得以歇息。
当先行词为situation、case、stage、point、activity、atmosphere等抽象名词,且引导词在定语从句中表示事情发生的情况、阶段等时,常用关系副词where引导。

when
Tip 3 why引导的定语从句
why表示原因,在定语从句中作原因状语,相当于“介词for+which”。Do you know the reason     he didn't attend the meeting 你知道他没参加会议的原因吗
在非限制性定语从句中,用for which表示原因而不用why。
I had told them the reason,for which I didn't attend the meeting. 我把我没有去开会的理由告诉了他们。




why/for which
三 、“介词+关系代词”引导的定语从句
Tip 1 介词和关系代词的确定
若介词放在关系代词之前,关系代词指人时用whom,指物时用which。另外,whose也可以放在介词后,即“介词+whose+名词”结构。一般来说,确定关系代词前的介词,可以从以下三方面入手:(1)先行词的意义;(2)从句中的动词或形容词的固定搭配;(3)句子的意思。
(2021·浙江1月)Chimps will check to see if they have the attention of the animal
①         they wish to communicate.黑猩猩会检查自己是否得到了想要与之交流的动物的关注。 I wish to thank Professor Smith,②        help I would never have gone this far. 我希望能够感谢史密斯教授,没有他的帮助,我不可能走这么远。 Recently I bought an ancient vase,whose price(=the price of which) was very reasonable. 最近我买了个古代的花瓶,它的价钱很合理。
