1、when where why引导定语从句用法要点1.先行词表示时间、地点、原因, 但关系词指代先行词在定语从句中充当主语或宾语时,应用关系代词that或which。如:Ill never forget the year 1976 was full of sadness. (作 语)我不会忘记充满悲哀的1976年。 I regret the days I wasted in the woods. (作 语)我后悔在森林里虚度的日子。 This is the factory produces cars. (作 语)这就是那个生产小汽车的工厂。 This is the factory he visi
2、ted yesterday. (作 语)这就是他昨天参观的工厂。 This is the reason is unreasonable. (作 语) 这是一个没道理的理由。This is the reason he raised. (作 语) 这是他提出的理由。 2. 关系副词有时相当于 “适当的介词+关系代词”。如: where=in/on whichThis is the room he lives. 这就是他住的房间。 I can see the desk there is a book. 我能看见上面有一本书的那张桌子。 when= on/in/at which I still rem
3、ember the year I joined the Party. 我仍然记得入党的那一年。I still remember the day I joined the Party. 我仍然记得入党的那一天。I still remember the date I joined the Party. 我仍然记得入党的那个日子。We shall never the days when/ in which we lived together. why=for whichThis is the reason he was killed. 这是他被杀害的原因。3. 当point, situation等词
4、作先行词表抽象的地点,其后常由where引导定语从句, where在定语从句中作地点状语。Can you think out a situation where this word can be used? 你能设想这个单词被使用的场合吗?Her illness has developed to the point where nobody can cure her. 她的病发展到没人能治的地步。 定语从句类似结构例析定语从句既是NMET命题的热点,又是中学英语教学中的重点和难点,其中有些句子是有关定语从句的,但也有些句子貌似定语从句而实际上是其它句型、句式,有的即使是定语从句却也截然不同。现
5、将这些句子集中在一起进行对比并作简析,以供参考。1(1)The house, whose roof was damaged, has now been repaired (2)The house, the roof of which was damaged, has now been repaired 析:句(1),(2)都是定语从句, whose of which,但whose必须在无定冠词the的名词前,而of which常放在有定冠词the的名词后。 2(1)John is one of the students who know English (2)John is the only
6、one of the students who knows English 析:句(1)、(2)都是定语从句,在the(only)one of复数名词定语从句结构中,先行词是one,而不是复数名词,故定语从句谓语动词用单数,但有one of复数名词定语从句句型中,先行词是复数名词,故定语从句谓语动词用复数。3(1)He failed in the exam again, as was expected (2)He failed in the exam again, which was not what he had expected (3)He failed in the exam again
7、, which made his parents angry 析:这三个句子都是非限定性定语从句,只是引导词不一样,而且as,which决不能互换。句中的as和which都是用来代替主句,而不是某个先行词。as可以放在句首,有正如之意,which不能放在句首,无正如之意。且定语从句是否定句时,用which而不用as。 4(1)Ill never forget the days(thatwhich)I spent with him(2)Ill never forget the day when I stayed with him析:句(1)、(2)都是定语从句,但句(1)中先行词days在定语从
8、句中作spent的宾语,故定语从句由关系代词that which引导,也可省略。句(2)中先行词day在定语从句中作时间状语,故定语从句可由关系副词when或on which引导。 5(1)Give me the reason why you are late (2)The reason that he gave us was unacceptable 析:句(1)是why引导的定语从句,相当于for which。句(2)是that引导的定语从句,that在定语从句中作gave的宾语。 6(1)Here is such a heavy stone as I cant move (2)Here
9、is such a heavy stone that I cant move it 析:句(1)是定语从句,先行词前有 such修饰时用as引导,as在定语从句中作move的宾语。句(2)是suchthat引导的结果状语从句。 7(1)This is the same key as I lost yesterday (2)This is the same key that I lost yesterday 析:句(1)和句(2)都是定语从句,但含义不同,句(1)是由as引导的,一般用在the sameas结构中,表达的意思是像.一样;故句(1)的意思是这把钥匙和我昨天丢的那把是一样的。而句(2
10、)是由that引导的定语从句,句(2)的含义是这就是我昨天丢的那把钥匙(是同一把钥匙)。8(1)I believed the man who I thought was honest (2)I believed the man whom I thought to be honest 析:句(1)who作定语从句的主语,故用主格,句(2)whom作thought的宾语,故用宾格。 9(1)This kind of plant grows best at the places where it is warm and wet (2)This kind of plant grows best whe
11、re it is warm and wet 析:句(1)是由关系副词where引导的定语从句,修饰先行词places,这时的 where也可以由at which代替。句(2)是由连接副词where引导的地点状语从句,这时的where不可以由介词which代替。 10(1)There are two boys in Peters, both of whom are white (2)There are two boys in Peters, and both of them are white 析:句(1)是含有定语从句的复合句。句(2)因为有并列连词and所以是并列句。 11(1)As is
12、known to us all, the light on the earth is given by the sun (2)It is known to us all that the light on the earth is given by the sun 析:句(1)是由as引导的非限制性定语从句,这时的定语从句的位置很灵活,可以位于句首,句末或插在句中。as代替整个主句,在定语从句中充当主语。句(2)是含有主语从句的复合句,it作形式主语,真正的主语是that引导的从句。 12(1)The sun is bigger than the moon, as we all know (2
13、)The sun is bigger than the moon, and we all know it析:句(1)是由as引导的非限制性定语从句,as代替整个主句,在定语从句中作know的宾语。句(2)是由and连接的并列句。 13(1)On May 5th we reached Beijing, where we stayed for a week (2)On May 5th we reached Beijing, and there we stayed for a week 析:句(1)属于由where引导的非限制性定语从句,先行词Beijing在定语从句中作地点状语。句(2)则是由an
14、d连接的并列句,there在句中作状语。14(1)It was October 1, 1949 when the Peoples Republic of China was founded. (2)It was on October 1, 1949 that the Peoples Republic of China was founded. 析:句(1)是由连接副词when引导的时间状语从句。句(2)是强调句型,强调句中时间状语on October 1,1949特别要注意句(2)中October之前的on。 15(1)The news that he told me is true (2)T
15、he news that he will come back from the USis true 析:句(1)是that引导的定语从句, that在定语从句中作told的直接宾语。也可以由which代替。句(2)是that引导的同位语从句,that在同位语从句中不作任何成分,只起连结作用,但一般不能省略,也不能用which代替。 定语从句专项训练1._ have plenty of money will help their friend.
