定语从句的用法以及精练
一、定语从句的概念
在复合句中,修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面。
二、定语从句的关系词
引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose)等,关系副词包where, when, why等。关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分。
三、定语从句的分类
根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
四、关系代词的用法
1. that 既可以用于指人,也可以用于指物。在从句中作主语或宾语,作主语时不可省略,作宾语可省略。例如:
Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语)
The coat (that) I put on the desk is blue.我放在桌子上的那件外套是蓝色的。(that作宾语)
2.which用于指物,在句中作主语或宾语,作主语不可省略,作宾语可省略。例如:
The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。(作主语)
The film (which) we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。(作宾语)
3.who, whom用于指人,who 用作主语,whom用作宾语。在口语中,有时可用who代替whom, 也可省略。例如:
The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。(作主语)
Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?(作宾语)
注意:(1)当定语从句中含有介词,介词放在句末时,who, that, which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构。例如:
This is the house in which we lived last year.这是我们去年居住的房子。
Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。
(2)含有介词的固定动词词组中,介词不可前置,只能放在原来的位置上。例如:
This is the person whom you are looking for. 这就是你要找的那个人。
(3)that 作介词的宾语时,介词不能放它的前面,只能放在从句中动词的后面。例如:
The city that she lives in is very far away.她居住的城市非常远。
(4)关系词只能用that的情况:
a. 先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which.例如:
He was the first person that passed the exam. 他是第一个通过考试的人。
b.被修饰的先行词为all, any, much, many, everything, anything, none, the one等不定代词时,只能用that,而不用which.例如:
Is there anything that you want to buy in the shop? 你在商店里有什么东西要买吗?
c.先行词被the only, the very, the same, the last, little, few 等词修饰时,只能用that,而不用which.例如:
This is the same bike that I lost.这就是我丢的那辆自行车。
d. 先行词里同时含有人或物时,只能用that, 而不用which.例如:
I can remember well the persons and some pictures that I saw in the room.我能清楚记得我在那个房间所见到的人和一些照片。
e.以who或which引导的特殊疑问句,为避免重复,只能用that.例如:
Who is the girl that is crying? 正在哭泣的那个女孩是谁?
f.主句是there be 结构,修饰主语的定语从句用that,而不用which.例如:
There is a book on the desk that belongs to Tom. 桌子上那本书是汤姆的。
(5)关系词只能用which,而不用that 的情况:
a.先行词为that, those时,用which, 而不用that.例如:
What’s that which is under the desk? 在桌子底下的那些东西是什么?
b.关系代词前有介词时,一般用which,而不用that.例如:
This is the room in which he lives. 这是他居住的房间。
c.引导非限制性定语从句,用which, 而不用that.例如:
Tom came back, which made us happy. 汤姆回来了,这使我们很高兴。
五、关系副词的用法
(1)when指时间,其先行词表示时间,在句中作时间状语。例如:
This was the time when he arrived.这是他到达的时间。
(2)where指地点,其先行词表示地点,在句中作地点状语。例如:
This is place where he works.这是他工作的地点。
(3)why 指原因,其先行词是原因,起原因状语作用。例如:
Nobody knows the reason why he is often late for school. 没人知道他为什么上学总迟到。
六。"介词＋关系代词"是一个普遍使用的结构
(1) "介词＋关系代词"可以引导限制性定语从句，也可以引导非限制性定语从句。"介词＋关系代词"结构中的介词可以是 in, on, about, from, for, with, to at, of, without 等，关系代词只可用whom或 which,不可用 that 。
例:Is that the house in which you live ?
(2)像listen to, look at, take care of等固定短语动词，在定语从句中一般不宜将介词与动词分开。例如：
This is the boy whom she has taken care of.

冠词 (关注重要考点)
冠词的词汇量最少,只有三个:a, an , the 。在选用冠词的时候应考虑三个因素：（1）名词是可数的还是不可数的（能否用a/an）；（2）是否在作一般的陈述，即是不是表示泛指(该不该用a /an)；（3）所指的东西听者或读者能否无误地识别，即是否需要特指(是否需用the)。
一．不定冠词a/an的用法：
1．开头字母为元音字母,但发音却为辅音音素的单词前要用a, 而不是an。如：
a unit 一个单位，一个单元；a uniform 一套制服；a university 一所大学；
a useful book 一本有用的书； a European 一个欧洲人
(注意这样的情况：There is a “u” in the word “sound”.)
2．以辅音字母开头，但是发音却以元音音素开头的词的前面要用an ,而不用a。如：
an hour 一个小时； an honest man 一个诚实的人
3．有些辅音字母的读音是以元音音素开始的，其前面也要用an, 而不是a。如：
an X-ray photograph 一张X光照片；
There is an “s” in the word “sit ” . 在单词sit里有一个s。
（注意：在强调a或an 时，则须分别读作/ /或/ /。）
4．“a / an + adj.+不可数名词”结构在英语里用得相当广泛。如；单独表达rain, wind , snow……时，他们是不可数的，可是前面有了形容词修饰的时 候，就可以用a/an来修饰，如：
a heavy rain 一场大雨；a light snow 一场小雪；a strong wind 一阵大风
5．“a + 序数词”表示“又一，再一”，并没有表示顺序的意思。如：
Can you give me a second chance, please? 你能再给我一次机会吗？（a second chance 相当于 another chance.）
There is a third boy over there.那边还有一个男孩。（说明这里有两个男孩，那边还有一个，但是这三个男孩和顺序排列无关。）
不定冠词的习惯用语的简单总结：
have a try试一试 have a look （at）看一看…… have a rest 休息一下 have a cold 感冒 have a drink (of) 喝一点…… have a good time 玩得很愉快
have a talk 谈话 have a party 聚会
have a pain 疼痛 have a good idea 有好主意
have a meeting 开会 a lot (of) 许多……
have a fever发烧 a little / few 一些，有一点 make a mistake 犯错误 have a cough 咳嗽
for a while 一会儿 after a while 一会儿以后
wait a minute 等一会儿 make a mistake 吵闹
go for a walk 散步 in a minute (while, moment)一会儿以后
二．定冠词the 的用法：
1．有些可数名词前加the，表示一类人或物。如：The lion is the king of animals.狮子是兽中之王。
(不过不可数名词表示一类，不加任何冠词。如：Water is a kind of matter.水是一种物质。)
2．在江河，海洋，海峡，湖泊，山脉，群岛前要加the。如：
the East Sea 东海 the West Lake 西湖
the Yellow River 黄河 the English Channel 英吉利海峡
the Alps 阿尔卑斯山脉 the Tianshan Mountains 天山山脉
（注意；“Mount Tai 泰山”前不加the。）
3．用于形容词或分词前，表示一类人。如：
the living and the dead 生者和死者
The young should speak to the old politely. 年轻人对老人说话要有礼貌。
4．“the +姓的复数”表示全家人或者夫妻俩。如：
The Zhangs are having lunch now. 张家正在吃午饭。
The Smiths are both English teachers. 史密斯夫妇俩都是英语老师。
5．有时the 用在副词，形容词的比较级前，指两者中“比较……的”那一个。如：
He is the taller of the two. 他是两者中较高的那个。
The fatter of the two men is my father. 那两个人中较胖一个的是我父亲。
6．the常用在same之前。如：
I think they are the same thing. 我认为它们是同一件事
在某些词组中有无定冠词含义不同。如：
go to school 去上学-- go to the school 去学校（不确定去做什么）
go to hospital 去医院看病--go to the hospital 去医院（上班或看望病人等）
go to church 去教堂（做礼拜）--go to the church 去教堂（不确定去做什么）
in class 在课堂上--in the class在教室里
at table 在桌子旁（吃饭）--at the table 坐在桌子旁（不确定做什么） （巧记：今天做了一道名菜，叫做“the”，把the吃进了肚子里，所以不加the 的at table就是坐在桌子旁吃饭）
in front of 在……的前面--in the front of 在……内部的前面（巧记：在第一讲已有陈述。）
in bed（卧病）躺在床上--in the bed 在床上（不一定是有病了。）
※ 从此可以看出不加定冠词的时候一般有某种具体的含义。
定冠词the的习惯用语的简单总结：
the day after tomorrow 后天 the day before yesterday前天
the same as 与 ……相同 on the left(right) 在左边（右边）
the other day 几天以前；前几天 by the way 顺便问一句
go to the cinema(theatre)去看电影（去剧院） in the day 在白天
in the morning 在早晨（上午） in the afternoon 在下午
in the evening 在晚上 in the end 最后，终于
all the year round 一年到头 at the end of… 在……的尽头
at the bottom of 在……的底部 at the top of 在……的顶部
in the distance 在远方 in the west of 在……的西部
on the way to… 在去……的路上 on the side of 在……的一边
※ 特别注意一点“零冠词+带定语的名词”结构，即在名词前有其他词，如物主代词，指示代词，不定代词，或名词所有格等等修饰时，不加冠词。如：
我的书 my book(√) the my book (×)
这一本书 this book (√) this a book(×)

冠词答案及解析：1-5：CBCDC 6-10：ABACB
1题考查“an用于元音音素开头的单词或字母前”的用法。h尽管是辅音字母，但是它的读音是以元音因素开始的。第5题同第1题，useful虽是以元音字母开头，但是读音却以辅音音素开始的，所以用a而不用an 。第7，10题均是考查不定冠词的这种用法。
2题考查了“the 用在世界上独一无二的事物前”的用法。本题的题意是“我们住的地球比月亮大。”
3题考查的是a /an 表示泛指“一，一个”。并且 a用于辅音音素开头的名词前；an 用于以元音音素开头的名词前。第4题和本题一个道理。
6题考查了a /an ,the 在固定词组里的用法。“have a bad cold 得了重感冒”，“stay in bed卧病在床” 。
8题考查the 表示特指的用法。根据题意知道是特指“穿蓝色衣服的那个夫人”。
9题考查“the 用在形容词的最高级前”的用法。题意为“最近的超市在哪里？”
