非限制性定语从句一般是不能省略be动词和关系代词的。
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)
