非限定性定语从句 一．限定性定语从句与非限定性定语从句的区别： 1.限定性定语从句与先行词不用逗号分开；非限定性定语从句与先行词往往有逗号隔开，如若将非限定性定语从句放在句子中间，前后都需要用逗号隔开。 2.限定性定语从句与主句的关系很紧凑，对其先行词起限定、修饰的作用, 从句不能省略,如果省略, 整个句子意思不完整；非限定性定语从句对主句起补充说明作用，从句可以省略, 缺少也不会影响全句的理解。 eg. ⑴ The old man has a son , who is in the army . 　那位老人有一个儿子，他在部队工作。 (2) The old man has a son who is in the army . 那位老人有一个在部队工作的儿子。 第2句所传达的信息是：可能老人还有其他的儿子在干别的工作。 二．非限定性定语从句引导词 1. 在非限定性定语从句中，关系词不能用that。 2. which引导的非限定性定语从句是用来说明前面整个句子的情况或主句的某一部分。 eg. (1) The Tangshan earthquake was felt in Beijing, which is more than two hundred kilometers away. (2) Tom said the work would be done by October, which I doubt very much. 3. as有时也可用作关系代词 。as引导非限制性定语从句，指代主句整个句子，若as在从句中作主语，其引导的句子可以放在句首，也可以放在句中。但which引导的非限制性定语从句只能放句中。 eg. As is reported in the newspaper，some cultural relics will be on show in the museum on the weekend. 三． as 作为非限定性定语从句的用法。 固定搭配中， 1) as is known (to all)=as we know; as is reported; as is expected=as we expected; as far as is concerned 等 2) the same…as; such…as；so…as eg. 1) He is such a strange person _______ nobody can get on well with. 2) He is such a strange person _______ nobody can get on well with him. 基础题： He left the money with his friend, _______ he believes was useful to him.
