高中定语从句（要解析,O(∩_∩)O谢谢）
Is the lab ____the foreigners visited yersterday?
A.that B.where C.in which D.the one
为什么答案是D?

高中定语从句（要解析,O(∩_∩)O谢谢）Is the lab ____the foreigners visited yersterday?A.that B.where C.in which D.the one为什么答案是D?
先把疑问句变成陈述句,
the lab Is ____the foreigners visited yersterday
而这时候没有承受对象,
所以加个THE ONE 作宾语.
可以省略关系词.
visit是及物动词,
不需要加介词,
而先行词the lab 在句子中作宾语,
所以选D.
做定语从句最好用还原法,
定语从句是英语基础语法的一部分,同时也是目前初中阶段初三语法（Module 7-Module 10）教学中的重要部分.对于面临中考的同学们,只需要掌握定语从句最基本的用法就可以了.比如说：that（先行词为人或物）,which（先行词为物）,who（先行词为人）,whose（先行词和whose 后面的名词成所属关系,不光是人之间的所属或是物之间的所属）以及引导词的省略（先行词在从句中只作宾语时）.对于which引导的非限定性定语从句,介词+关系词,关系代词和关系副词的区别等将不作为中考的重点.
同学们可能在一开始接触定语从句的时候有些发憷,做题时感觉云里雾里,通过多年教学我发现,采用“还原法”能帮助学生理清思路,甚至在理解关系代词和关系副词(why,when,where)的区别方面也有很大帮助.（这一部分同学们理解就可以了,也可以作为参加竞赛的必备之题）.
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.也就是说：把先行词还原到定语从句中的方法.
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分,以选择正确的关系词和删掉不必要的词.
例1.连接下面两个句子：
Australia is the country.Most British people would like to visit it.
可见先行词是the country,答案应为：Australia is the country that/which/不填most British people would like to visit.有的同学会把it还放到句子当中,因为没有还原,如果我们还原一下的话,应为：Most British people would like to visit the country.显然这个it在定语从句中就多余了.这里的先行词在句中作宾语.
例2.再看下面两道书中的例子：
The cartoons that/which/ 不填 I like have lots of jokes.
There were kangaroos that were jumping alongside the car.
第一句先行词cartoons还原到定语从句中为：I like the cartoons,显然先行词在定语从句中作宾语,我们知道只要是先行词作宾语的时候,关系代词都是可以省略的.不作宾语的情况,都不可以省略关系代词.如：第二句,还原后句子为：Kangaroos were jumping alongside the car.我们发现先行词在定语从句中作主语,这个时候就不可以删掉that.
例3.区别下面两道题：
He has moved to the house _____ he was born.
A.which B.that
C.when D.where
He has moved to the house_________is newly repaired.
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与介词一起作地点状语,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.
例4.This is the reason_____he asked us to work out the plan.
A.because B.why
C.which D.when
例5.This is the reason_____he gave us for working out the plan.
A.because B.why
C.which D.when
例4、例5的先行词都是the reason,但通过还原,我们知道前一句中the reason还原后担当了定语从句的原因状语,即he asked us to work 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 working out the plan,C为正确选项.
2.把问句还原成陈述句,有助于正确理解句子.
例6.Is this museum ______we visited last year?
A.where B.the one C./
例7.Is this the museum_____ we visited last year?
A.where B.the one C./
把例6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7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,可以帮助学生理解语法知识,提高答题的准确率.
跟踪练习及讲解
1.That middle-aged woman ____ is talking to the headmaster is our new teacher.
A.whose B.which
C.who D.whom
答案：选C,因为还原先行词在句中做主语,故不可以选whom(只有先行词在句中作宾语的时候才可以选whom).
2.Thank you very much for the present ______.
A.you sent me
B.that you sent it to me
C.which you sent it
D.you sent it to me
答案：选A,还原后为：You sent me the present.宾语it要删掉了.
3.The professor __ has come.
A.who invited to give a talk to us
B.who was invited us a talk
C.who was invited to give us a talk
D.whom invited us to give a talk
答案：选C,还原后professor作句子的主语,故不选D,而且被动关系,又因be invited to do sth.,故不选B.
4.What do you think of the plan ______ at the meeting?
A.he brought it up
B.that he brought it up
C.he brought up
D.who he brought up
答案：选C,句中bring up表示提出之意,显然为bring up the plan,先行词在句中作宾语,故关系代词可为that/which/不填,又因it重复,则选C.
5.Can you lend me the novel _____ the other day?
A.that you talked
B.you talked about it
C.which you talked with
D.you talked about

a visit 后直接加宾语所以用that

D。首先要把找到主句部分，是Is the lab？把它变成陈述语气，是the lab is，很明显，这个句子缺少一个表语，因此要先选择一个能充当表语的选项，是D。至于这句话为什么没有关系词，从句中谓语visit是及物动词，但是它后面并没有宾语，因此，先行词the one 在从句中充当宾语，可以省略关系词。...
