that 可用于表示时间、地点、方式、理由的名词后取代when, where,
why引导的定语从句,在口语中that常被省略。
This is the
place (that / where / in which) he works. 这是他工作的地方。
非限制性定语从句
关系代词和关系副词在非限制性定语从句中的应用与在限制性定语从句中类似。先行词为人时,用who, whom, whose;先行词为物时,用which。 that不用于非限制性定语从句中。
Mary has a brother, who is an engineer. 玛丽有一个兄弟,他是一位工程师。
She has six cousins, three of whom lived to grow up.
她有六个表兄弟,其中三个已经长大成人了。
The children are taught by a 32-year-old Englishman, whose wife is
an American.
孩子们的老师是一位32岁的英国人,他的妻子是美国人。
非限制性定语从句也可以由where或when 引起。
Last week we visited Hangzhou,
where there is a beautiful lake.
上周我们游览了杭州,那儿有一个美丽的湖。
We will put off the party until next week, when we won't be so busy.
我们把晚会推迟到下周,那时我们就不会这么忙了。
