2. 这些关系副词在定语从句中有什么作用？

点拨精讲
当先行词为表示时间的名词(如：day, time, week, month, year等)，且关系词在从句中作时间状语，定语从句用when引导。
1. I still remember the time when I was in college.
2. we will never forget the day when we flew at an altitude of 6000 meters in the sky.
1. when引导的定语从句
当先行词为表示具体地点的名词(如：place, house, airport等)或抽象地点的名词(如：point, case, situation, stage, position, condition等) ，且关系词在从句中作地点状语，定语从句用where引导。
1. This is the hotel where they stayed.
2. we have reached a point where a change is needed.
3. He gets into a situation where it is hard to decide what is right or wrong.
2. where引导的定语从句

2. I don’t know the reason why he didn’t turn to his friends for help yesterday.

观察例句
1. Do you remember the days when we chatted with each other all night
2. Do you remember the days that/which we spent studying together in the classroom
3. I don't know the reason why he didn't turn to his good friend for help yesterday.
4. We won't accept the reason that/which you have given.
5. Can you recognize the house where you used to live with your parents
6.Can you recognise the house that/which Tom sold three years ago
注意辨析
表示时间、地点及原因的名词作先行词时，先行词在定语从句中作状语时，应用关系副词；若先行词在定语从句中作主语或宾语时，则应用关系代词。
方法：分析从句句子成分
如何区分关系代词和关系副词引导的定语从句
用法 依据
根据从句的谓语动词 是及物动词，后面若无宾语，用关系代词；是不及物动词则用关系副词
根据先行词在从句中所作的成分 把先行词代入定语从句中，若作主语或宾语用关系代词；作状语则用关系副词
定语从句的引导词用关系代词还是关系副词可以用以下两种方式判断：
1. when相当于“ at/in/on/during等 + which”
I remember the day ________________ I settled in China.
2. where 相当于“ in/at/on等 + which”
The house ________________ Mark lived is now a library.
3. why 相当于“for + which”
Is that the reason ________ she suddenly changed her mind
5. “介词+关系代词”引导的定语从句
1. 关系副词when，where，why引导定语从句时，也可用“介词+which”代替关系副词。
when (=on which)
where (=in which)
why (=for which)
1. This is the student __________ I bought a book.
2. This is the ship _________ I went to Shanghai.
2. 在“介词+关系代词”引导的定语从句中，关系代词只能用which或whom,不可用that/who。先行词指物时用which，先行词指人时用whom。
for whom
by which
(二)选用介词的依据
1. 根据先行词的搭配，, 从句中的动词、形容词等的搭配 (即固定短语)。
(1)Yesterday we visited the West Lake ___________ Hangzhou is famous.
(2) He is the student___________we should learn.
(3) I remember the days ____________I lived here.
(4) I can’t remember the age _________ he won the prize.
2. 根据句子的意思来选择。
(5) This is the pilot _________ my brother has worked for ten years.
(6) This is the pilot ___________ my son was saved.
for which
from whom
during which
at which
with whom
by whom
3. “名词，不定代词或数词 + of + which (指物)/whom (指人)”在定语从句中作主语，说明整体中的一部分。
1. China has lots of islands, ____________ is Hainan Island.
2. The building had been repaired, _________________ was
destroyed again in a big fire.
3. Miss Liu has a lot of students, ______________ are girls.
one of which
the roof of which
some of whom
1、介词选择的三原则：一先二动三意义。
一先：根据先行词的搭配习惯来确定。
二动：根据从句中谓语动词的搭配习惯来确定。
三意义：根据从句所表达的意义来确定。
1.I’ll never forget the day ___________ I joined the army.
2.The factory ___________ his father works is far away from my hometown.
