定语从句讲义及练习
一、定语从句的分类
1) 限制性定语从句:从句不可少,没有它,先行词的意思不明确,主句也不完整。与先行词之间不用逗号。
Mary is a girl who has long hair.
2) 非限制性定语从句:是对先行词的补充说明或描绘作用,没有它不会影响先行词或主句意思的完整性。 从句一般用逗号同主句分开。
George, who is my classmate, has won a scholarship.
二、定语从句中主谓一致的问题
当关系代词在定语从句中作主语时,定语从句中的谓语动词要与先行词的人称和数保持一致(我们要知道,关系代词所代指的就是先行词,这里有一个等量关系)。
1 当先行词是 one of + 复数名词,定语从句的位于动词要用复数形式
The Great Wall is one of the world-famous buildings that draw lots of visitor every year.
2 当先行词是 the only + one of +复数名词,从句谓语用单数形式
The Great Wall is the only one of the buildings on the earth that is seen from the moon.
③ 先行词如果是整个句子,定语从句的谓语动词用单数
Great changes have taken place in China, as is known to all.
He has passed the driving test, which surprises all of us.
三、as, which 引导非限定性定语从句的差别
关系代词as和which都可用来引导非限制性定语从句,都可用来指代主句或主句中的名词或短语,一般可互换,但用法有以下区别:
① as 引导的定语从句可置于句首、句中、句末,而which不可。
As we all know, he never smokes.
②在从句中作主语时,which既可作连系动词be的主语,也可作实义动词的主语;而as只可作连系动词be的主语。
He married her,which/as was natural.他和她结婚了,这是很自然的事。
He saw the girl, which delighted him.他见到那个女孩,这使他很高兴。
③非限定性定语从句中出现expect, think, suppose 等表示猜测、想象、预料等时。
She succeeded in her doing the research work, as we expected.
④as 的用法 the same… as; such…as 中的as 是一种固定结构, 和……一样……。
I should like to use the same tool as is used here.
We should have such a dictionary as he is using.
四、way和time后接定语从句的用法。
①当先行词是way(方式、方法)时,
如果先行词way后面的定语从句中缺少主语、宾语、表语,则引导词用that/which/不填。
The way that/ which/ 不填 he explained to us was quite simple.
他向我们解释的那种方法很简单。
如果先行词way后面的定语从句缺少(方式)状语,则引导词用that/in which/不填。
The way that/ in which/ 不填 he explained the sentences to us was not difficult to understand.
他向我们解释句子的那种方法不难理解。
②当先行词是time时(时期、次数)时,
如果time表示“次数”,应用关系代词that引导定语从句,that可省略。
It is the first time(次数) that Mr. Smith has visited China.
这是史密斯先生第一次到中国游览。
如果time表示“时期,一段时间”,应用关系副词when或at/during + which引导定语从句。
There was a time(时期) when/during which there were no radios, no telephones and TV sets.
曾经有一个没有收音机,没有电话,也没有电视的时期。
五、关系副词where
高考试题中对于where的考查趋于复杂,从先行词为“明显的地点”转化“模糊化的地点”。事实上,对于where这个词,考生不能只理解为表地点,当先行词表示某人/物的situation,或某事所发展的stage和point,或表达某事的某个方面时都可用where这个关系副词。常见的抽象名词作先行词的有:point, position, situation,stage,state,case, scene,dilemma等。
He said if we ever got to the point where we needed to use life jackets, he would have already died of terror.他说假定我们真的到了需要用救生衣的地步,他早就吓死了。
六、“介词+关系代词”的用法
有时定语从句中的介词可以提到关系代词前面,形成“介词+关系代词”结构,该结构中的关系代词可用which, whose, who 不可以用that和who。该结构中的介词可以根据定语从句中谓语的搭配、与先行词的搭配或者句子的意义来确定。
e.g. This is the house of which I spoke. (根据动词speak的搭配而定)
This is the camera with which he often takes photos. (根据先行词的搭配而定)
This is the pilot by whom my son was saved.(根据句子的意义来确定)
注: 有些“动词+介词”短语,如look for, look after, call on 等不可拆开,不可把介词放在关系代词之前。
He is the old man who/whom we looked after last year. 他是我们去年照顾的那个老人。
That is the book which I am looking for. 那就是我要找的书。
