什么是表语,关系副词,关系代词
知识点(语法)
解题思路: 表语属于句子成分范畴。关系代词和关系副词是连接定语从句中的关系词。
解题过程:
表语就是放在连系动词,如 be,become, get,seem 等等之后,用来说明主语的身份,特征或状态等.
一般由名词,代词,形容词,副词,不定式,介词短语等充当。例如(在例句中,表语用大写体表示):
1.Work is STRUGGLE. (名词)
工作就是斗争.
2.Mr.Zhang became a TAXI DRIVER. (名词)
张先生成为出租车司机了.
3.Our future is BRIGHT. (形容词)
我们的前途是光明的.
4.He is OUT. (副词)
他出去了.
5.These books are YOURS. (代词)
这些书都是你的.
6.Two times four is EIGHT. (数词)
2乘以4是等于8.
7.The result of the test is DISAPPOINTING. (分词)
测验的成积令人失望.
8.Her work was WASHING and COOKING. (动名词)
她的工作是洗衣服和做饭.
9.Your task is TO LOOK AFTER these children. (不定式)
你的任务是照顾这些孩子们.
10.Her mother is IN GOOD HEALTH. (介词短语)
她的妈妈很健康.
11.What surprised us most was THAT YOU SPOKE ENGLISH SO WELL. (从句)
最令我们大为吃惊是你英语说得这么好.

引导定语从句的关联词称为关系词。关系词有关系代词和关系副词之分。关系代词有that, which, who, whom, whose, as等;关系副词有where, when, why等。关系词常有3个作用:1,引导定语从句。2,代替先行词。3,在定语从句中担当一个成分。
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。

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:
