定语从句的选择题

有没有关于“定语从句的选择题”答题的技巧？“What That Which When”的区分~！总是答不好这种题……

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.

先行词中有序数词修饰关系代词当然是用that”，但that是关系代词?在定语句中有两个作用：
1）代替前边的先行词，又起到连接主句和从句的 作用：
2）在从句中 作成分（主，宾，），作宾语时可省略
在该句I shall come here to help you（主 谓 状）中，不缺主语，宾语，怎么会用that呢？缺 的 是状语，先行词又是指 时间，从句I shall come here to help you缺 的 是时间状语“在何时the last time ”，所以本题该选B when。
别忘了：：选择 关系代词还是副词时 比须 同时 具备两个条件：：（1）先行词指人还是物？（2），在从句中 作什么成分？ 这 正是 选择that 还是when ,where 的 难点：
A.This is the best time ？I'll never forget.
B.This is thefirst/last time？_He'll be punished.
C. This is the place ？he had ever lived.
D.This is the place ？he will live in.
E. This is the last/first place ？_he will visit.
答案：A,that,B.when C. where,D.that /which.E. that/which

Answer 3

就是看一下定语从句里面却什么成分，缺主语，宾语，表语用which, that
句子里面缺状语就要看先行词了，时间用when地点用where
定语从句里面没有what
