答案
定语从句中:只用that而不用which的五种情况
引导定语从句的关系代词有:that(指人或物),which(指物),who (指人).指人时可用that或who ;指物时可用that 或which ;但有时只能用that,不能用which.常见的情况有下列五种:
1) 当先行词是:all ,any ,anything ,everything ,nothing或被它们修饰时.例如:
Is there anything that I can do for you
有什么可以为你做的吗?
All that can be done must be done .
凡是能做的都必须做.
2)当先行词被形容词的最高级或序数词修饰时.例如:
That is one of the most interesting books that are sold in the bookshop .
那是这家书店出售的最有趣的书之一.
The first thing that we should do is to get some food .
我们该做的第一件事是弄点吃的.
3)当先行词有:the only ,the very ,the same ,the last 等修饰时.例如:
My necklace is not the only thing that's missing .
我的项链不仅是丢掉的东西.
4)当主句以who或which开头时,定语从句中引导词用that ,不用which 或 who .以避免重复.例如:
Who is the girl that is wearing a red coat
正穿一件红色外套的女孩子是谁?
5)当先行词既有人又有物时,用that .例如:
The writer and his novel that you have just talked about are really well known .
你刚才谈起的那位作家以及他的小说确实很著名.
