练习 关系代词引导的定语从句 关系副词引导的定语从句 限制性定语从句和非限制性定语从句 As引导的定语从句以及与其他关系代词的比较 “介词+关系代词”引导的定语从句 关系代词和关系副词的选择 定语从句在四级,六级的听力、阅读和翻译中经常出现,是需要重点把握的语法点之一。 在把握定语从句的时候大家要注意以下几点: 1. 定语从句的作用主要是用来修饰先行词; 2. 定语从句和主句之间需要有关系词来进行连接; 3. 关系词在从句中代替先行词,并且充当一定的成分。根据关系词在从句中成分的不同,关系词是有所不同的。 例1: Great changes have taken place in the?factory? ?where???we are working. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?先行词? ??关系词????由where引导的从句 在这个例句中,factory是先行词,由where引导的定语从句来修饰;同时由where替代的这个先行词在从句中作状语。如果仍然不能分清结构,可以把句子拆分: 主句: Great changes have taken place in the?factory. 从句: We are working?in the factory. 关系词如何选择?可以分三步走: 第一步,首先确定先行词; 第二步,然后确定它在定语从句中做什么成分; 第三步,之后可以进行具体分类。 1. 先行词是人:如果在从句中做主语,关系词用who;做宾语,用who 或whom;做定语,用whose 例2: He is the person who/whom we are looking for. 2. 先行词是物:在从句中做主语或宾语都用which;作定语用of which, 或whose; 例3: This machine which I have looked after for years is still working perfectly. ? 注意: 1) 如果先行词在从句中做状语,表示时间、地点和原因,关系词就要使用when,where和why. 如例1的情况就是先行词在从句中充当地点状语,因此用where. 2)?在限定性定语从句中,which, who, whom?都可以被that?取代。所以例2、例3中的关系词也可以省略。 3) 非限制性定语从句通常标志,从句和主语之间用逗号隔开。 例4: This is a critical problem in the company,?which?need to be solved immediately. 这个句子就是非限定性定语从句,在这种情况下,关系词通常用which。 1.
