定语从句在句中作定语,修饰名词或代词,被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。 那么怎样判断定语从句?下面我们去了解一下吧!
一、定语从句的识别:
名词(句子)+连接词+句子
其中识别度最高的关键之处,就是连接词,它有三种:
① 关系代词:who, whom, that, which, as, whose
② 关系副词:when, where, why, how
③ 介词+关系代词:介词+whom, 介词+which, 介词+whose
但注意,有时你会看到 in that,但in that=because,算是一种固定搭配,这和定语从句没关系。
这里单独说一下as引导的定语从句吧,因为其它都还比较常见,as相对来说比较生疏。
主要是在same和such之后,定语从句用as引导,但偶尔the same后面也用that.
如:I've never heard such stories as he tells.
我从来没听到过他讲的这种故事。
He is wearing the same suit as(或that) he wore at Mary's wedding.
他穿着与他在玛丽的婚礼上穿的一样的衣服。
二、定语从句的处理
原则:将定语从句完整地切分出来,独立成句。
两个关键点:① 完整地切分;② 独立成句
第一步,切分:切分点在连接词前,如果连接词前有介词那就在介词前。
如:I love this girl / who is beautiful.
I went to Changchun / where I met my wife for the first time.
I have three books / of which the red is my favorite.
第二步,找指代(也就是关系代词的指代对象):
如:This is the expert / to whom we are turning.
注:turn to = resort to = 求助于……
这句话里的关系代词是 whom , 它的指代对象是the expert.
所以这句话翻译过来是:这就是我们正在求助的那个专家。
第三步,调语序
需要调整语序的也就是关系代词和(介词+关系代词)
还是上面那句话:This is the expert to whom we are turning.
先切分,① this is the expert /
② to whom we are turning
再找到第②句中whom的指代对象,whom=the expert
也就是 to the expert we are turning
这时落实到我们要讲的调语序了,因为我们发现to the expert we are turning,它由于受到定语从句规则的限制,所以不是正常语序,现在我们把它变成正常语序就是:we are turning to the expert
这时,你再翻译成中文时就没有障碍了。
至此,我们总结一下,定语从句的处理就是分三步,1.切分;2.找指代;3.调语序
这样就可以完成了将一个定语从句从英文到中文的转换,所以下次遇到定语从句时,你只管先“咔嚓”来一刀,给它切开,两个句子安安静静地出现在你面前,你就别么费劲地去前置了,那么定语从句就不能前置了吗?也不是不能,语义如果挺顺畅的.你就前置呗,只是能前置的定语从句基本上都退化成后置定语了,比如,an apple which is on the table也可以写成an apple on the table(桌子上的苹果)
a way which is to solve the problem也可以写成 a way to solve the problem(解决这个问题的方法)
定语从句的几个难点
难点一:定语从句与并列句的区别
观察下面三个句子:
Hong failed in the College Entrance Examination, ________ disappointed his mother.
Hong failed in the College Entrance Examination and ________ disappointed his mother.
Hong failed in the College Entrance Examination; ________ disappointed his mother.
(提示:判断是定语从句还是并列句,要注意句中的标点符号和句中的连接词。)
例1:Tom’s mother kept telling him that he should work harder, but _____ didn’t help.
h
例2:The weather turned out to be very good, _____ was more than we expected.
h
e
例3:The mother told her lazy son to work instead of staying at home; ____ didn’t help.
h
难点二:介词+关系代词引导定语从句中介词的选择
“介词+关系代词”可引导限制性定语从句也可引导非限制性定语从句,可从以下几点定位关系代词前的介词。
1.介词与先行词搭配是一种固定搭配
I still remember the day ____________ I first came to school.
The company ______________ I once worked has changed much.
2.介词与从句中动词的搭配
He is a man of great knowledge, _____________ much can be learned.
In the dark street, there wasn’t a single person _____________ she could turn for help.
3.介词与从句中形容词的搭配
China is a beautiful country, _____________we are greatly proud.
The teacher talked about some subjects _________________ the students were interested.
4.与名词之间的搭配
He may be late, ________________ we ought to wait for him.(如果是这样)
Call me at six o’clock, __________________ I should get up.(到那个时候)
Ex:
(1)There is a room, _______________________ faces the river.
那儿有一间房子,窗户面对这条河。
(2)They are the very people _______________________ for help.
他们就是那些你可以向其求助的人。
(3)China has many islands, _______________________ Taiwan is the largest.
中国有很多岛屿,台湾是其中最大的一个。
(4)They arrived at a house, _______________________.
他们到达一所房子,前面坐着一个小男孩。
(5)Gun control is a subject ________ Americans have argued for a long time.
which which
t which which
(6)By nine o’clock, all the Olympic torch bearers had reached the top of Mount Qomolangma, ________ appeared a rare rainbow soon.
which which
which e which
(7)For many cities in the world, there is no room to spread out further, _____ New York is an example.
which which
which which
注意:The way ________ he explained to us was quite simple.
The way ________ he explained the sentence was simple.
难点三:引导词as , which
1.引导非限制性定语从句,指代整个主句内容时的区别:
(1)表达“正如”之意时,用as, 如果仅指代整个主句内容而没有“正如”之意,则用which。
He went abroad, ______ was unexpected.
She is a good mother, _____ her mother used to be.
(2)当从句位于主句前面时,用as。
______ is known to everybody, the moon travels round the earth.
2.限制性定语从句中有such, the same 时,其后常用as 引导定语从句。
He is such a good teacher _______ we all love and respect.
This is the same pen _______ I lost.
h既可指代整个主句内容,又可以指代先行词。
The river, _______ flows through London, is called the Thames.
常与从句中的know, see, hear, expect等动词连用,也常用于as often happens, as is often the case等句子中。
He was absent from school, _______ is often the case.
难点四关系代词与关系副词(补全法或还原法)
you still remember the chicken farm ________ we visited three months ago?
