学生活动:在教师的引导下,总结限制性定语从句的规则。
·The relative adverb where refers to a place, the relative adverb when refers to (1) time, and the relative adverb why refers to (2) a reason.
·In more formal English, the relative adverbs where, when and why can be replaced by "preposition+ (3) which".
二、While-class
教师活动:向学生介绍关系副词引导的限制性定语从句
定语从句也可以由关系副词(relative adverbs)when,where,why引导,关系副词在定语从句中作状语。
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,moment,day,year,month,week,period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 wins 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。
注意:
当先行词是表示时间的名词时,既可以用when引导定语从句,也可以用that 或which引导定语从句,关键要看关系词在定语从句中作什么成分。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 together on 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。
The school where his sister works is a key middle school in Jiangsu Province.
他姐姐工作的那所学校是江苏省的一所重点中学。
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。
(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。
注意:
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。
辨析:比较where引导的定语从句和状语从句
①where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
附近有没有一个商店可以让我们在里面买些水果?
②where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。
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。
注意:
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。
三、After-class
教师活动:指导学生完成第49页B1。
① I did not perform well at school last week. The reason was my poor-quality sleep.
The reason why I did not perform well at school last week was my poor-quality sleep.
或 The reason for which I did not perform well at school last week was my poor-quality sleep.
② Those were the days. I used to sleep really well in those days.
Those were the days when I used to sleep really well.
或 Those were the days in which I used to sleep really well.
③ The hospital is near my home. I visited a doctor for advice on sleep problems in that hospital.
The hospital where I visited a doctor for advice on sleep problems is near my home.
或 The hospital in which I visited a doctor for advice on sleep problems is near my home.
④ I still remember that afternoon. That afternoon I fell asleep on the bus and went past my stop.
I still remember that afternoon when I fell asleep on the bus and went past my stop.
或 I still remember that afternoon in which I fell asleep on the bus and went past my stop.
