———定语从句难点突破定语从句是学生解题的难点，下面就定语从句的难点进行归纳总结，从而让学生深刻地领悟理解定语从句，进而掌握解题技巧。
1.先判断先行词是人还是物。
2.确定关系代词或关系副词代替先行词在定语从句中充当何种句子成分。
3.还原定语从句，检验先行词在定语从句充当的成分。
在处理综合试卷的过程中，遇到这样的一道题：He didn’t put the things ____ they belonged, for＿＿reason he got his punishment.（D）A.which; thatB. what; thisC. that; whoseD. where; which学生答错率较高。
“他没有把那些东西放回到他们本该在(原来)的地方，为此他受到了惩罚。
” 第一空语境分析，东西应放在什么地方。
Where引导状语从句时意为“在…的地方”；结构分析，belong 为不及物动词，常用固定搭配belong to。
They belonged句从结构上说选出的词只能用来做状语；如句子为they belonged to则要补足宾语。
第二空reason 前的限定词为that/this，故应用which 来连接相当于and for this/that reason。
类似的用法有in which case、during which time相当于and in that/this case、during that time。
1. Mark was a student at this university from 1999 to 2003, ____he studied very hard and was made Chairman of the Students' Union. （05重庆）AA. during which timeB. for which timeC. during whose timeD. by that time2. They stayed with me for two weeks, _______ they drank all the beer i had . CA. whichB. which timeC. during which timeD. during which3. I may have to work late, in which case I‟ll telephone.CA. in whose caseB. in whichC. in which caseD. in that case一、Such…that引导的状语从句与such…as引导的定语从句的区别：Such…that引导的状语从句，that引导的是一个完整的句子；而such…as引导的定语从句，as在定语从句中充当句子成分。
如：His plan was such a good one _______ we all agreed to accept.中，应用as，因为we all agreed to accept 缺少宾语，完整的句子为we all agreed to accept it.如为His plan was such a good one _______ we all agreed to accept it,则应用that, 因为we all agreed to accept it 是一个完整的句子。
1. I don't like such books ____ he recommended. AA. asB. thatC. soD. after which2. Mr. Smith is _________ a good teacher _________ we all respect him. AA. such, thatB. such, asC. so, thatD. so, as3. Such a book ___ you lent me is too difficult to understand. CA. thatB. whichC. asD. like二、一些特殊的先行词如situation, point, case, activity，scene及period, festival, occasion等要注意具体情况具体分析。
这些词基本上都是表示时间、地点的词，做具体题目时，要判断他们在定语从句充当的成分来决定关联词。
主语、宾语和表语用that/which，状语用where/when/介词+which。
如：There is one point______ we must insist on.We‟re just trying to reach a point ___ both sides will sit down together and talk. 第一句定语从句可还原为：we must insist on the point,所以先行词point在定语从句中作宾语，故用that或省略。
第二句定语从句可还原为：at the point both sides will sit down together and talk, 故先行词point在定语从句中作状语，所以关系词用where/介词+which。

表示时间、地点先行词以及先行词为reason、way在定语从句中作状语时，相应的用: 表示时间的先行词：when/介词+which；表示地点的先行词：where/介词+which；reason为先行词：why/for which/that/…/; way为先行词：in which/that/…/但解题关键要判断先行词在定语从句中作状语还是作主语、宾语和表语。
作状语，则适用上面得语法规则，如作主语、宾语和表语，则仍需用that/which（作宾语that/which可省略）。
This is the reason ____ he gave me.This is the reason ____ he didn‟t come to school today.第一句定语从句可还原为：he gave me the reason, 先行词reason在定语从句中作宾语，故关系词用that/which或省略；第二句定语从句可还原为：for the reason he didn‟t come to school today, 故关系词用why/for which/that或省略。
