语法解读:英语定语从句讲解与练习
展开is a hardwrking student wh always gets first in his class.
汤姆是一个用功的学生,他在班里总是第一名。(修饰名词student。)
Ftball is played ver 80 cuntries, which makes it ppular.
80多个国家都在踢足球,因此足球很流行。
(修饰整个主句Ftball is played ver 80 cuntries。)
先行词与关系词
1.什么是先行词:被定语从句修饰的名词、代词称为先行词。可以这样理解,之所以称它为先行词,是因为先行词总是出现在定语从句之前,而不同于普通形容词修饰名词,形容词常位于名词之前。
’t frget the bk that I tld yu t bring.
别忘了我让你带的书。(the bk为先行词。)
2.先行词与关系词的关系:引导定语从句的词被称为关系词。关系词根据其在定语从句中的功能可分为关系代词和关系副词。关系代词在定语从句中作主语、宾语、表语、定语等,关系副词在定语从句中作状语。
含有定语从句的句子一般分为两层:即主句层(第一层),定语从句层(第二层)。
特别提示:
①关系词一般紧跟在先行词之后引导定语从句。定语从句总在被修饰的先行词后面。
②在定语从句中,关系代词起着代词和连词的作用,关系副词起着副词和连词的作用。
③在定语从句中,关系词代替先行词,因此在定语从句中不能再重复作用相当于先行词的词。
下面的句子是错误的:
This is the right bk that yu are lking fr the bk.(应去掉the bk。)
This is the right bk that yu are lking fr it.(应去掉it。)
关系词的种类
①常见的关系代词
chemistry teacher is a man wh/that can make his class lvely and interesting.
我们的化学老师可以使他的课堂生动有趣。
(主格wh/ that在定语从句中作主语,代指人a man。)
Mr. White invited many friends t his party whm/wh/that he respected much.
怀特先生邀请了很多他十分尊敬的朋友来参加他的宴会。
(宾格whm/ wh/ that在定语从句中作respected的宾格,代指many friends。)
②常见的关系副词
marks in places where yu have questins.
在你有问题的地方做出标记。
(where为关系副词,在定语从句中作地点状语。)
I still remember the time when we first met scres f years ag.
我依然记得几十年前我们第一次见面的情景。
(when为关系副词,在定语从句中作时间状语。)
特点提示:选择关系代词三步骤:
步骤一:首先找出先行词。
bk that/which yu just laid n the tp shelf is mine.
你刚才放在高层书架上的书是我的。(the bk是先行词,指物。)
步骤二:确定先行词在从句中所作的成分。
先行词the bk在后面的定语从句中作laid的宾语,因此选择指物的关系代词which/that作宾语。
步骤三:确定关系代词的人称和数。
在此处由先行词the bk可知是第三人称单数,如果关系代词作主语,则从句的谓语动词相应用单数。
关系代词的用法
(1)关系代词有:wh, whm, whse, that, which, as。
如果要修饰方式,用that或in which引导,或者不用引导词。
e.g.I dn’t like the way (that, in which) he eyed me.
我不喜欢他看我的那个样子。
(2)关系代词wh在从句中主要作主语,在非正式语体里wh还可以作从句中的宾语。
is the man wh wants t see yu.
他就是想要见你的那个人。(wh在从句中作主语)
(3)关系代词whm。
is the man whm I saw in the park yesterday.
他就是我昨天在公园里见到的那个人。
(whm在从句中作宾语)
作宾语用的引导词可以省略,因此上面的句子可以改写如下:
He is the man I saw in the park yesterday.
(4)关系代词whse用来指人或物,(只能用作定语,若指物,它还可以同f which互换)。
pass me the bk whse (f which) cver is green.
请递给我那本绿皮的书。
(5)关系代词which指物,在从句中作主语或宾语,作宾语时在非正式语体中可以省略。
needed a plant which didn’t need as much water as rice.
他们需要一种不像水稻那么需要水的作物。(作主语)
注意:当有which和that要进行选择的情况下,以下情况要选which:
①在非限制性定语从句中通常用which作引导词,而不能用that做非限制性定语从句的引导词。
②修饰整个主句。
e.g.I never met Julia again after that, which was a pity.
从那以后我再也没有见到过朱莉叶,真是遗憾。
③修饰谓语部分
can swim in the river, which I cannt.
他会在河里游泳,那正是我不会的。
④介词+which
are all questins t which there are n answers.
那些问题都是无头公案。
(6)关系代词that多用来指物,有的也可以用来指人;在从句中作主语或宾语。指物的时候多用that,也可用which。
’s a questin that (which) needs careful cnsideratin.
这是一个需要仔细考虑的问题。(指物,作主语。)
注意:在以下的情况中,只能用that作引导词,而不能用which作引导词:
① 先行词为all, everything, anything, nthing, little等不定代词时。
that she lacked was training.
她所缺少的只是训练。
注意:everything等为先行词时,引导词可以省略。
② 先行词被形容词最高级修饰时。
is the best film that I have ever seen.
这是我看过的电影中最好的一部。
③ 先行词被序数词和the last修饰时。
④ 先行词中既有人又有物时。
talked abut the teachers and the schls that they had visited.
他们谈论他们参观过的那些学校和老师们。
⑤ 主句是含有wh或which的特殊疑问句,为了避免重复时。
(7)关系代词as用于引导限制性定语从句时,多数和such…as和the same…as连用。
e.g.I have never heard such a stry as he tld.
我从未听过他讲的这种故事。
注意:as和which的区别:
关系代词as用于引导非限制性定语从句时,应注意以下几点:
① as引导的非限制性定语从句位于句末时,一般可以和which互换。
authr was brught up in a small village, as (which) is recunted in sme f his stries.
作者是在一个小村庄里长大的,这个问题在他的一些小说里已被提到过。
但是,当主句是否定句时,as和which就不能互换,因为as引导的非限制性定语从句不包含否定意义。
② as引导的非限制性定语从句可以放在句子的最前面,而which引导的定语从句不能放在句首。
yu will find ut, all is nw settled.
你将会看到这样一种情况,一切都已搞定了。
关系副词的用法
常用的关系副词有where, when, why, that等。这些关系副词在定语从句中作状语。注意:关系副词里面没有hw。
(1)where的用法:在定语从句中作地点状语,指代地点。此时常可用in which, n which, at which, t which等结构代替。
can be grwn in places where it is t cld t grw rice.
(=Ptat can be grwn in places in which it is t cld t grw rice.)有些太冷不能种稻米的地方,可以种马铃薯。
(2)when的用法:在定语从句中作时间状语,往往代指时间。此时常可用n which, in which, at which, during which等代替。
e.g.I shall never frget the days when we wrked n the farm.
(=I shall never frget the days n which we wrked n the farm.)
我永远也不会忘记我们在农场劳动的那些日子。
(3)why的用法:why在定语从句中作原因状语。可以用fr which代替。why不可引导非限制性定语从句,此时可用fr which代替。
e.g.I have cme arund t explain the reasn why I was absent frm the meeting.
我来是为了向你解释我当时没到会的原因。(why在从句作原因状语。)
(4)that的用法
在表明方式、时间或地点的先行词后面,常用that来代替in which,when或where,that也可省去。that在句中不作任何成分,只起到引导定语从句的作用,修饰的先行词常为the way, the time, the day, the place等,此时也可换为其他相应的关系副词。
① 表示方式时。that(=in which)常省略。此时不能用hw引导定语从句,但把the way去掉之后。可直接用hw引导方式状语。
yu wrk ut a way (that/ in which) we can slve this prblem?你能找出一种我们可以解决这个问题的方法吗?
(that在定语从句中不作成分。)
② 表示地点时,that(=where=介词+which)也可省略。
e.g.I have never been t the places(that/ where/ in which) the Indians live.
我从未到过那些印第安人居住的地方。
(that在定语从句中不作成分。)
③ 表示时间时,that(=when=介词+which)也可省略。
e.g.I still remember the days (that/ when /n which) I helped my father n the farm.
我仍然记得在农场上给我爸爸帮忙的日子。
(that在定语从句不作成分。)
④ 另外,关系副词that有时还可用来代替关系副词why,表示原因。
reasn that (=why)he lst his life was lack f medical care.
他的死是由于缺乏医疗护理。
特别提示:在下面这个句子中,不能用why,只能用which或that。
I dn’t want t hear any reasn (that/ which) yu might give.
我不想听你给出的任何理由。
(在这个定语从句中,that/ which作定语从句中谓语动词give的宾语。)
(5)关系副词的省略
① 在某些表示时间的名词后的关系副词可以省略。如the time, every time, each time, the mment等。
the time (when) he was furteen years ld Einstein had learnt advanced mathematics all by himself.
到十四岁时,爱因斯坦已经自学了高等数学。
D yu still remember the day(when) we first met?
你仍然记得我们第一次相遇的那一天吗?
② 在某些句子中表示地点的名词后关系副词有时也可以省略。如the place等。
’s the place (where) he lived when he was in Paris.
这就是他在巴黎时所住的地方。
This is the place (where) we met years ag.
这就是多年前我们见面的地方。
③ 先行词the reasn后面的关系副词可以省略。
’s the reasn (why) I asked yu t cme.
这就是我叫你来的原因。
The reasn (why) he did that is quite clear.
他那样做的理由是非常清楚的。
④ 当先行词是way时,关系副词常常省略。
e.g.I appreciate the way (that) yu teach us.
我非常喜欢你教我们的方式。
注意事项
1.主谓一致问题
这是指关系代词在定语从句中作主语时,定语从句中谓语动词的单复数形式与先行词一致的问题。
① 取决于先行词,先行词是单数时,从句的谓语动词用单数;先行词是复数时,从句的谓语动词用复数。
Smith, wh is nw dwnstairs, is asking t see yu.
史密斯先生要见你,他现在正在楼下。
(定语从句的谓语动词is根据Mr. Smith而定。)
The Smiths, wh are nw dwnstairs, are asking t see yu.
史密斯夫妇要见你,他们正在楼下。
(定语从句的谓语动词are根据the Smiths而定。)
② “ne f+复数名词”作主语,谓语动词用复数形式;“the(nly, very, right) ne f+复数名词”作主语时。谓语动词用单数形式。
is ne f the students wh were awarded.
杰夫是当时获奖的学生之一。
(本句的先行词是the students,即所修饰的中心词为the students,因此谓语动词应根据the students而定。)
Jeff is the nly ne f the students wh was awarded.
杰夫是唯一一个获奖的学生。
(本句的中心词移到了the nly ne,因此定语从句的谓语动词需根据the nly ne而定。)
2.what,hw不可引导定语从句
① what本身是复合关系代词,等同于“先行词+关系代词(which/that)”。因此不能用what引导定语从句。
is what we demand mst.
(=Time is all (that) we demand mst.)
我们所需要的就是时间。
Tell me what is happening.
(=Tell me smething that is happening.)
告诉我正在发生什么事。
She isn’t what she used t be.
(=She isn’t the ne (that) she used t be.)
她不是过去的她了。
② hw为复合关系副词。本身等同于the way in which,因此,不能用hw引导定语从句。
e.g.I dn’t like hw yu behave.
(=I dn’t like the way (that/ in which) yu behave.)
我不喜欢你行事的方法。
This is hw I wrked ut this prblem.
(=This is the way (that/ in which) I wrked ut this prblem.)
这就是我解出这道题的方法。
