定语从句中要注意的问题

怎样学好定语从句

Answer 1

1、需要注意的问题
保持谓语和先行词的一致
e.g. He is one of the greatest writers who are living now.
e.g. He is the only one of the boys who has joined the army.
whose引导定语从句时，人、物皆可。
不能只看先行词，还要注意引导词在句子中充当什么成分。
避免关系词的重复，被关系代词说替代的部分不可在从句中重复出现。
e.g. This is the book we have read it together.
reason, way后关系词的用法
e.g. This is the reason (for which/ why/ that) he was absent yesterday.
e.g. I don’t like the way (in which/ that) he does everything.
在比较级中，than充当关系代词，在从句中作主语。
e.g. The results of his study have turned out to be more satisfactory than was expected.
2、使用that的几种情况
先行词前有形容词最高级或序数词修饰
先行词前有不定代词修饰，如the same, the only one, all, both, everything, nothing
当主句是以who, which开始的特殊疑问句时，从句用that，避免重复
先行词既指人，又指物
e.g. We know nothing about the doctors and the hospital that you are talking about.
关系代词充当表语
e.g. He is not the man that he used to be. = He is not what he used to be.
3、where引导的定语从句和地点状语从句
where引导的定语从句必须有先行词。如：place, school, city, house, room等
where不是修饰性名词，而是修饰其前整个句子，在句子中作地点状语。
e.g. Make a mark where you have any questions.
4、when, where, why引导的定语从句和同位语从句的区别
相同点：在两种从句中都可以充当状语成分
不同点：○1作关系副词引导定语从句时有跟它们含义相应的先行词
○2作关系副词引导定语从句时，可以改为“prep. + which”来引导
○3作连接副词引导同位语从句时没有与它们含义相应的先行词
e.g. I’ll never forget the day when (= on which) we met for the first time.
e.g. I have no idea when we met for the first time.

18. 定语从句
　　定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，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。
　　关系代词有：who, whom, whose, that, which等。
　　关系副词有： when, where, why等。
18.1 关系代词引导的定语从句
　　关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that
　 这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
　 Is he the man who/that wants to see you?
他就是你想见的人吗？（who/that在从句中作主语）
　 He is the man whom/ that I saw yesterday.
他就是我昨天见的那个人。（whom/that在从句中作宾语）

2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：
　 They rushed over to help the man whose car had broken down.　 那人车坏了，大家都跑过去帮忙。
　 Please pass me the book whose (of which) cover is green.　请递给我那本绿皮的书。

3）which, that
　　它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
　　A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语）
　　The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语）
