定语从句是英语基础语法的一部分,同时也是高中阶段语法教学中的重要部分。但许多高一学生在定语从句的掌握和运用方面存在困难,做题时感觉云里雾里,采用“还原法”能帮助理清思路。
一、何为“还原法”
“还原法”是指将因语法需要而改变的句子恢复其原来的模式,以检验所做的答案正确与否。
二、“还原法”的运用
1.将先行词还原到定语从句中,确定其在句中所充当的成份,以选择正确的关系词
例1 He has moved to the house____he was born.
A.which B.that C.when D.where
例2 He has moved to the house____is newly painted.
A.which B./ C.when D.where
这两个句子粗看似乎一样,但若分别把先行词house还原到定语从句中:第一句为“He was born in the house.”,house与介词一起做地点状语,应选择D;第二句定语从句还原为“The house is newly painted.”,先行词在句中作主语,关系代词不可省略,所以选择A.
再看下面两题:
例3 This is the reason____he asked us to carry out the plan.
A.because B.why C.which D.when
例4 This is the reason____he gave us for carrying out the plan.
A.because B.why C.which D.when
例3、例4的先行词都是the reason,但通过还原,我们知道前一句中the reason担当了定语从句的原因状语,即he asked us to carry out the plan for the reason,故应选B;后一句中the reason充当定语从句的宾语,即he gave us the reason for carrying out the plan,C为正确选项。
2.还原主句,理清主从句之间的关系,以免误入“陷阱”
例5 Alac asked the policeman____he worked to contact him whenever there was an accident.
A.with him B.who C.with whom D.whom
如果把he worked to contact him理解为定语从句,那就很难明白先行词the policeman与定语从句的关系。因此,我们应先还原主句:Alac asked the policeman to contact him whenever there was an accident,此时我们就能明白先行词the policeman与定语从句的关系是“he worked with the policeman”,所以根据句意应该选择C.
例6 I'll do everything____you.
A.I can to help B.I can help C.what I can to help D.that I can help
在选择时,学生很容易想到情态动词can后接动词原形,会选B或D.但用还原法来检测一下,就会发现主句应为:I'll do everything to help you,其中every thing是定语从句I can(do)的先行词,关系代词that省略,所以A才是正确答案。
3.把问句还原成陈述句,有助于正确理解句子
例7 Is this museum____we visited last year?
A.where B.the one C./ D.at which
例8 Is this the museum____we visited last year?
A.where B.the one C./ D.at which
把例7还原成陈述句This museum is____we visited last year,我们就可清楚地看到从句前缺少先行词和关系代词,因而应该选B(the one=the one that)。但如果把例8还原成陈述句This is the museum____we visited last year,我们会发现本句有先行词,只是缺少相应的关系代词,因此应选择C(句中省略了that或which)。
总之,利用还原法做题,可以帮助我们理解语法知识,提高答题的准确率。
