1.when引导定语从句的用法
(1)当先行词是表示时间的名词（如time,day,year,month, week等)，且关系词在从句中作时间状语时，定语从句用 when引导。
(2)when可以换成"介词+which"。
◆Winter is the time of year when(in which )the day is short while the night is long.冬天是一年中昼短夜长的时候。
◆She is looking forward to the day when (on which )her daughter will win a gold medal at the Olympics.她盼望着她的 女儿在奥运会上赢得金牌的那一天。
13
特别提醒：当先行词是表示时间的名词时，若关系词在定语从句中充当状 语，则用when引导；若关系词在定语从句中充当主语或宾 语，则用that或which引导。
◆Do you still remember the days that/which we spent togetheron the farm 你还记得我们一起在农场度过的那些日子吗？(that或which作spent的宾语)
◆Do you still remember the days when we chatted with each other all night 你还记得我们整夜聊天的那些日子吗？(when在从句中作状语)

2.where引导定语从句的用法
(1)当先行词是表示具体地点的名词（如place, room, mountain,airport等)或表示抽象地点的名词（如case,state, condition,point,situation等)，且关系词在从句中作地点状语时，定语从句用where引导。

15
◆We have reached a point where a change is needed.我们已经 到了需要做出改变的地步。
◆He gets into a situation where it is hard to tell what is right or wrong.他陷入一种难以判断对错的境地。
16
(2)where可以换成“介词+which”
◆This is the hotel where (=in which) they stayed.
这就是他们 待过的那个旅馆。
17
特别提醒 ：当先行词为表示地点的名词时，如果关系词在定语从句中 作主语或宾语，则用that或which引导定语从句。
◆His father works in a factory which/that makes radio parts.他 的父亲在一家制造收音机零件的工厂里工作。
18
辨析比较 ：where引导的定语从句和状语从句
(1)where引导定语从句时，为关系副词，在定语从句中作地点 状语，其前有一个表示地点的先行词。此时，where可以换成 "介词+which"结构。where引导的定语从句只能位于主句之 后或句中，不能位于句首。
◆Is there a shop around where (=in which) we can buy some fruit
附近有可以买到水果的商店吗？
19
(2)where引导状语从句时，为从属连词。where引导的地点状 语从句修饰主句中的谓语动词，where前面没有表示地点的名 词。此时，where不能换成"介词+which'"结构。where引导的地 点状语从句可位于主句之前，也可位于主句之后。
◆Where there is a will,there is a way,[谚]有志者，事竟成。
◆ We should go where we are needed.我们应该到需要我们的地 方去。
20
3.why引导定语从句的用法
(1)当先行词是表示原因的名词reason,且关系词在从句中 作原因状语时，定语从句用why引导，且只能引导限制性定 语从句。
(2)why可以用for which来代替。
◆This is the reason why(=for which)he left in a hurry.这就 是他匆匆离去的原因。
21
特别提醒：
若先行词为reason,且关系词在定语从句中不作状语，而是 充当主语或宾语，则用that或which引导定语从句。
◆The reason that he told me yesterday is a lie.昨天他告诉我 的理由是个谎言。
①April Fool's Day is a day people play jokes on friends.
②The factory his father works is in the east of the city.
③I'll never forget the days _ we worked on the farm years ago.

Step 3
1.判断主句和从句；
2.判断是否有连词连接两个句子。
1. 主句中找到先行词，根据先行词判断填写合适的关系词；
2.重读句子，将先行词放入从句中看句子是否完整（如果考察关系副词需要加介词放从句中）。
无连词：
1.判断空格是否在从句中做主语、宾语或表语；
2.如果缺少则考察定语从句关系代词；不缺少则考察定语从句关系副词。
