定语从句是高中英语教学的一大重点，也是高考考查的一大热点。现笔者从05年全国高考单选题型中搜索相关考查项加以分析，窥其特点，研其解法并配以专练，希望能对广大考生决胜于高考助一臂之力。

1.（05.全国卷Ⅰ.24）I have many friends, __ some are businessmen.

  A. of them    B.  from which     C.   who of     D.  of  whom      

  分析：选D。定语从句先行词为friends指人，只能在C，D中选。而many与some构成对比的数量关系，即选D，指“其中一些朋友”。

2.（05.天津卷.13）Last month, part of the southeast Asia was struck by floods, from_ efforts the people are still suffering.   A. that    B.  whose      C.  those    D. what 

分析：选B. 在定语从句只选A，B。that 前面不要介词而排除A，因而选B表所属关系。

3.（05.上海卷.40）If a shop has chairs__ woman can park their men, women will spend more time in the shop.    A.  that    B.  which   C.  when     D. where  

分析：C. which表时间，定语从句只能在A，B，D中选择。先行词虽是chair. 但从句不缺主宾而排除A，B，因而选D。在从句中when做地点状语，意思为：如果商店里若有供来陪妇女们来购物的男人们坐的话，妇女们则会在商店里呆更长的时间。

4.（05.广东卷35）Many people who had seen the film were afraid to go to the forest when they remembered the scenes__  people were eaten by the tiger.

A. that    B. by which    C.  which      D. in which

分析：选D。先行词为scenes, 定语从句中需要in the scene 做状语，意思才完整，因此需要关系副词where= in which  即 选D。

5.（05.山东卷30）He was educated at a local grammar school, __ he went on to Cambridge.

 A. from which    B. after that  C. after which    D. from this

分析：选C。 定语从句引导词在A、B、C中选。在A、C中知after which指“他在当地一所语法学校上的学，之后去剑桥”，选C。

6.（05.江苏卷32） The place __ the bridge is supposed to be built should be__ the cross-river traffic in the heaviest.

A. which, where   B. at which, which   C. at which, where  D. which, in which

分析：选C。先行词是place, 其后定语从句中缺相关地点状语，用where= at which.

7.(05.浙江卷27) Jim passed the driving test,__ surprised everybody in the office.

  A.  which    B. that  C.  this     D.  it

分析：选A。定语从句在A，B中选， which 指前面整个句子。

8.（05.福建卷35）-Is that the small town you often refer to ?

-          Right, just the one__ you know I used to work for years.

  A. that    B.  which    C.  where   D.  what 

分析：选C。先行词为the one表地点，其后定语从句缺少相关地点状语而选where=in which.

9.(05辽宁卷28) I walked in our garden, __ Tom and Jim were trying a big sign onto one of the trees.      A. which    B.  when   C. where    D.  that   

分析：选C。先行词garden指地方，其后定语从句缺少相关地点状语。

10（05.江西卷25）The schools themselves admit that not all children will be successful in the jobs __ they are being trained.

A. in that   B. for that   C. in which    D. for which  

分析：选D。that 前面不要介词排除A、D，由上下关系看用for which.

11.(05.安徽卷29)  Her sister has become a lawyer ,__ she wanted to be.

A.   who     B.  that   C. what   D.  which    

分析：选D。a lawyer指职业，用which.

12.(05.安徽卷32) Great changes have taken place in that school. It is no longer__ it was 20 years ago,__ it was so poorly equipped.

A. what, when    B. that, which   C. what, which    D. which, that   

分析： 选A。 第一个从句为what引导的表语从句；第二个为when引导的非限制性定语从句，表时间。

由05年高考题来看，考查的热点内容有四方面：

1.关系代词和关系副词应用到定语从句的不同指代特征，如who(whom)/that/which/whose; where/when/how/why/as. 2.关系代词which和as. which 为关系代词，引导定语从句是指物或事，在从句中做主语或宾语。As作关系代词引导定语从句常与 the same 和such连用，或用来指代一个句子的内容，此时从句可放句首，通常用于as we see, as we know, as it is, as is know等结构中。3.关系代词与介词的搭配。关系代词whom, which前有什么介词搭配有两点：一看所修饰的名词与什么介词结构构成固定结构或习惯用法；二看从句中的动词与什么构成固定结构或习惯用法。4.非限制性定语从句。其中不用关系代词that,另外名词、代词、数词等+of + which/whom 用于非限制性定语从句，表示某个范围的人、事或物的某些情况。

方法提示：

我分为三个原则来解答定语从句题，原则一：

在平时，我们一定会发现对定语从句三大热点引导词who , that, which的考察频频出现,而此三词的用法极其复杂,它是广大考生记忆的极大障碍。笔者在多年从教实践中偶得一法——数学关系式解答法，即 who  >  that   >  which。

由以上关系式看出：who、that、指代人，而两者同时出现时优先选who；that、which 指 代物，而两者同时出现时优先选that。但要注意关系式存在的以下四个特殊条件：1.that 前面不用逗号或介词。2.that即可指人又可指物。3.要避免重复使用同一个引导词：who 本身是先行词时,引导词用that; that本身是先行词时,引导词用which。4暗含的表所属关系的 whose = of whom 或of which。
