定语从句十大难点定语从句是中学英语教学的语法重点，也是难点。

如试题1中指代先行词house的关系词作in的宾语，而不是状语，所以答案为A。

关系词在从句中作状语时，应选择关系副词(where地点状语，when时间状语，why原因状语)。

如试题2中的关系词the days在从句中作状语，而不是宾语(从句中的宾语是our holidays)；试题3中的关系词在定语从句中作主状语。

比较：①I live in Wuxi，which is famous for Taihu Lake．②I live in Wuxi，where Taihu Lake is protected by law．例①，which在从句中作主语；where在从句中作状语。

that与which的区别1．限制性定语从句的先行词指物，而且关系词在从句中作主语或宾语时既可以用that也可以用which，但是that不能引导非限制性定语从句，如试题4。

2．先行词是不定代词all，few，little，much，anything，nothing等词，关系代词用that。

3．先行词被序数词、形容词最高级以及all，any，every，few，the very，the only修饰时，用that作关系代词。

如试题6。

4．在which疑问句中，关系代词用that而不用which。

如试题7。

which与where的区别如果定语从句分别修饰point，situation，activity．condition和case等表示抽象意义的词，而且关系词在从句中作状语，意思是“到了某种地步，在某种境况中”，此时用where引导定语从句。

如试题13。

“介词+关系代词”结构中的介词及关系代词的选择关系代词作介词宾语，介词可前置，此时只能用whom．which而不能用that，who构成“介词+which／whom”的结构。

该结构中介词的选择，一要看先行词；二要看与定语从句谓语动词的搭配；三要看句意。

如试题9，period后面的定语从句中缺少时间状语，要用when，而此题中没有when，所以要选择in which相当于in the period。

再如试题10，先行词direction和定语从句的谓语come之间要用介词from。

注意：1．若为短语动词(即固定搭配)，那么介词不能放在关系词前面，如：look after，take care of，look for等。

2．关系副词在意义上相当于“介词+which”。

I was in Beijing on the day when(=on which) he arrived．The office where(=in which) he works is on the third floor．This is the chief reason why(=for which) we did it．“不定代词、数词或名词+of which／whom”引出非限制性定语从句。

表示整体中的一部分。

如：There are 40 students in our class，27 of whom are boys．我们班有40名学生，其中27名是男生。

例如试题11是“代词+of whom”结构，先行词是人，所以用whom。

试题14，是“名词+of、which”结构。

关系代词whose的用法先行词在定语从句中作定语用whose。

I’ve got a car，whose type is popular．我拥有一辆小汽车，其车型现在非常受欢迎。

又如试题12，其中whose company又作介词in的宾语。

此题关键弄清关系词与后面的名词的所属关系，问题就迎刃而解了。

此外，whose从句可转换为“名词+of which”型，如试题14从句部分可以改写为：whose hands were set with small diamonds。
