三.关系副词引导的定语从句
1.先行词在定语从句中作状语时,要用关系副词。
1)先行词是“时间词语”,用when引导定语从句。when=表时间的介词(in,at,during等)+which
e.g. I still remember the day when(=on which) I joined the army.
2)先行词是“地点词语”,用where引导定语从句。where=表地点的介词(in,at,on,under等)+which
e.g. Can you tell me the office where(=in which) he works?
3)先行词是reason时,用why引导定语从句。why=for which
e.g. The reason why(=for which) he didn’t attend the meeting was that he was ill.
△难点:高考对where的考查
where从先行词为明显的“地点”转为“地点的模糊化”。即,当先行词表示某人/物的situation,或某事所发展的stage,或表达某事的某个方面的都可用where这个关系副词。
e.g. They have reached the point where they have to separate with each other.
四.关系代词与关系副词的比较
技巧:①分析句子结构,看表时间或地点的先行词在定语从句中是作状语还是作主语和宾语。
②看定语从句的动词是及物动词还是不及物动词,或者是不及物动词+介词
e.g. This is the place ____ he worked.
The city ______ we visited is well known.
Do you know the reason ____ he is absent.
I didn’t believe the reason ______ he gave me.
We’ll never forget the day ______ we spent in the village.
We’ll never forget the day ____ we worked in the village.
The house ______ we stayed in belonged to Mr.Black.
The house in ____ we stayed belonged to Mr.Black.
五.限制性与非限制性定语从句
1.区别
限制性定语从句对先行词起修饰限制作用;而非限制性定语从句是对先行词起补充说明作用,且先行词与定语从句往往有逗号隔开。
e.g. He gave up the plan,which was a very good one.
2.非限制性定语从句中关系代词和关系副词的用法
1)关系词在任何情况下都不能省略。
2)who(主语),whom(宾语),which(主语,宾语)不能用that代替,也不能互相替换。
3)“介词+which/whom+从句”结构中,介词不能移到从句的后面。
4)when,where可用于非限制性定语从句,why不可。
e.g. ①That student that the teacher thinks best played truant(逃学)yesterday,which made the teacher very disappointed.
②Some pre-school children go to a day-care center,where they learn simple games and songs.
六.定语从句中的谓语动词与先行词保持一致。
当引导定语从句的关系代词在从句中作主语时,那么定语从句中的谓语动词的数应与先行词保持一致。
1.one of+复数名词+关系代词+复数动词
e.g. The Great Wall is one of the famous buildings that draw lots of visitors.
2.the only one of+复数名词+关系代词+单数动词
e.g. The Great Wall is the only one of the buildings on the earth that is seen from the moon.
注意: not the only one of…=one of…
e.g. Tom isn’t the only one of the boys who have passed the exam.=
Tom is one of the boys who have passed the exam.
3.当as与which引导非限制性定语从句,修饰主句内容时,若as与which作主语,则从句的谓语动词用单数形式。
e.g. Great changes have taken place in Zunyi,as/which is known to all.
七.注意way和time后接定语从句的情况
1.当先行词是way意为“方式、方法”时,关系词又是作状语时,用in which/that/不填;若关系词作宾语时,用that/which/不填。
e.g. The way ______ he explained to us was quite simple.
The way ______ he explained the sentence to us was difficult to understand.
2.当先行词是time时,若作“次数”讲,应用that引导定语从句,而且可省略;若作“一段时间”讲,应用when或at/during+which引导定语从句。
e.g. ①I could hardly remember how many times ____ I’ve failed.
②This was at a time ______ there were no radios,no telephones or no TV sets.
