定语从句在高中英语中一直占据较为重要的地位,在新课程的英语教材中也是如此。高考复习做题时,如果能确定题目为定语从句,可以按以下步骤进行操作:
找出先行词→将先行词代入定语从句,观察还原后的句子是否完整或还需添加适当的介词或副词→确定先行词指人或指物,并选择相应的关系代词或关系副词。
例:1)I still remember the days _____ we spent together in the countryside.
A. when B. which C. who D. where
2)I still remember the days _____ we spent our holiday in the countryside.
A. when B. which C. who D. where
解析例1:首先,确定先行词the days;其次,将the days代入从句,还原从句,句子为:We spent the days together in the countryside。句子完整,无需添加任何介词或副词,可见,先行词在从句中做动词spent的宾语;最后,先行词the days指物,因此选择答案B。
解析例2:首先,确定先行词the days;其次,将the days代入从句,还原从句,句子为:We spent our holiday in the countryside during the days。句子需添加介词during才完整,可见,先行词the days在从句中充当时间状语;最后,先行词the days指物,确定答案为A。
掌握定语从句时,以下的语言知识点一定要知道。
1、定语从句有限制性定语从句与非限制性定语从句,其明显差别为含非限制性定语从句的复合句在主句与从句之间有逗号。
2、在限制性的定语从句中,如果从句中的介词或副词提至从句的最前面,那么关系代词只能用which或whom,当然这里还可使用关系副词where。
3、先行词既可指人又可指物,在从句中既可做主语又可做宾语的关系代词that和which在用法上的不同应当明确,其中非常重要的一点为在非限制性的定语从句中是不能用that的。
4、关系代词as的用法。
1)在限制性定语从句中。如果先行词有the same或such修饰,而且先行词在从句中做主语或宾语,关系代词用as。要学会区别"the same…as…"与"the same…that…"。而"such…as…"与"such…that…"的不同,可以通过例句感知、归纳,如:① The newspaper is such a popular daily _______ we all love to read. ② The newspaper is such a popular daily _______ we all love to read it.例句①里的a daily在从句中做read的宾语,所以是一个定语从句,应填as;例句②里的a daily在从句中中不做任何成分,从句动词read已有宾语it,从句句意完整,是一个结果状语从句,应填that。
2)在非限制性定语从句中。as引导的从句指代整个主句,位置非常灵活,可以放在主句的前面、后面或者中间,而在非限制性定语从句中同样可以指代整个主句的关系代词which引导的定语从句只能放在主句的后面。
5、定语从句与一些相似从句的辨析:
1)定语从句与同位语从句
① Have you heard the news that he told this morning?(定语从句)
②Have you heard the news that he won this morning?(同位语从句)
2)定语从句与强调句
① It was the school where we got to know each other and became friends.(定语从句)
② It was in the school that we got to know each other and became friends. (强调句)
3)定语从句与时间状语从句
①We got to the village at the time when it was still bright.(定语从句)
