限制性定语从句和非限制性的区别

Question

如题所述

Answer 1

定语从句可分为限制性定语从句与非限制性定语从句。限制性定语从句与先行词关系密切，对它有限制作用。因此不可缺少，否则会影响全句的意义。限制性定语从句前一般不用逗号。如：
What is the name of the boy who brought us the letter? 给我们带信的那个男孩叫什么名字?
There is much which will be unpleasing to the English reader. 有许多东西将会使英国读者不愉快。
The teacher told us that Tom was the only person that was reliable. 老师告诉我们，汤姆是惟一可依赖的人。
I shall never forget the day when we first met in the park. 我永远不会忘记我们在公园相见的那一天。
Is there a store around where we can get fruit? 附近有可以买到水果的商店吗?
Do you know the reason why I came late? 你知道我迟到的原故吗?非限制性定语从句只与先行词有一种松散的修饰关系，写的时候关系代词和先行词之间要用逗号隔开，因此从句中的关系代词不能省略。that一般不引导非限制性定语从句。如：
I like to chat with John, who is a clever fellow. 我喜欢与约翰交谈，他是个聪明人。
Water, which is a clear liquid, has many uses. 水是一种清澈的液体，有许多用途。
Once more I am in Boston, where I have not been for ten years. 我又一次来到了波士顿，我有十年没有到这里来了。
非限制性定语从句形式上是从句，其功能实质上相当于一个分句，关系代词和关系副词实际上相当于连接词加上代词或副词的功能，如：
Then he met Mary, who invited him to a party. 后来他遇到玛丽，玛丽邀请他去参加晚会。(who实际上=and she)
When he was seventeen he went to a technical school in Zurich, Switzerland, where he studied mathematics and physics. 他17岁时，到瑞士苏黎世一专科学校上学，他在那里学习数学和物理学。(where=and there)
有时描述性定语从句的含义相当于一个状语从句。如：
We don’t like the room, which is cold. 我们不喜欢那个房间，它很冷。(which is cold=since it is cold)
He said he was busy, which was untrue. 他说他很忙，其实不然。(which was untrue=though it was untrue，which was untrue的先行词是前面整句宾语从句he was busy）
I want him, who knows some English. 我要他，他懂得些英语。(who knows some English=for he knows some English)
希望我能帮助你解疑释惑。
