定语从句是高考的热点，主要考查关系代词和关系副词的正确运用，特别是它们在非限制性定语从句中的运用。主要考点有：
①关系代词which引导的非限制性定语从句；
②关系副词where引导的定语从句(近三年来常考查先行词是表示抽象空间概念的名词的情况)；
③“介词＋关系代词”引导的非限制性定语从句；
④as引导的非限制性定语从句。

1．whose引导的定语从句
whose在定语从句中作定语，后面要接名词，其含义是“(先行词)的……”。whose既可以指人也可以指物。
(1)表示物时相当于“the＋名词＋of＋which”或“of＋which＋the＋名词”。
(2)表示人时相当于“the＋名词＋of＋whom”或“of＋whom＋the＋名词”。
2．whose引导的定语从句与并列句的区别
whose引导的定语从句易与含有物主代词its，their的并列句混淆。如：
China has the 3rd longest river in the world，whose name is the Yangze River.(定语从句)
China has the 3rd longest river in the world，and its name is the Yangze River.(并列句)

不是地点胜似“地点”——“模糊化的地点”要用关系副词where
高考试题中对于where的考查趋于复杂，从先行词为明显的“地点”转为“模糊化的地点”。事实上，对于where这个词不能只理解为表地点。当先行词是表示某物的situation/case，到了何种地步(point)，或某事物所发展的阶段stage，或表达某事的某个方面(scene)时，都可用where。
They have reached the_point_where they have to separate with each other.他们已经到了必须分手的地步。
Later in this chapter cases will be introduced to readers where consumer complains have resulted in changes in the law.(where＝in the cases)消费者的抱怨导致法律的改变的案例将在本章稍后向读者介绍。
这些不是地点胜似“地点”的名词的归属问题即当不当“地点”看是解答这类定语从句的关键。

as引导限制性定语从句常用于下列句式
(1)
其中关系代词as在从句中充当主语、宾语或表语。如：
We have found such materials as are used in their factory.我们已经找到了像他们工厂里用的那种材料。(as作主语)
These houses are sold at such a low price as people expected.这些房子以人们预料的那样的低价出售。(as作宾语)
He is not the same man as he was.他和过去不同了。(as作表语)
注意：such...as...引导的定语从句与such...that...引导的状语从句的区别：
第一个句子中as引导的是定语从句，因为从句中缺成分；而第二个句子中that引导的是状语从句，从句中不缺任何成分。
(2)．..such as...
such为代词，意为“这样的人或物”，as在从句中作成分，修饰先行词such。如：
This book is not such as I expect.
这不是我想要的书。(as作宾语)

如何选择“介词＋关系代词”中的介词
在“介词＋关系代词”引导的定语从句中，介词的选择是关键，也是考生深感头痛之处。介词的选择可依据以下原则：
(1)根据该介词和先行词的固定搭配来确定。
I admire my English teacher very much from whom I learn a lot.(learn from sb为固定搭配)
(2)根据定语从句中的动词习惯搭配来确定。
There are some people to whom you can turn.(turn to sb为固定搭配)
(3)根据从句中的形容词搭配来确定。
He introduced me some reference books with which I am not very familiar.(be familiar with为固定搭配)
(4)表示“所属关系”或“整体中的部分”时用介词of。
She has seen many films，of which Kung Fu Panda is her favorite.
(5)有一些动词短语不能拆开，如pay attention to，look after，take care of等。

有时命题者为了加大试题难度，往往把定语从句融入到其他结构中考查考生的语言综合运用能力，其常用的命题手段就是定语从句与先行词被某些句子成分分隔开，使考生分不清楚句子结构，从而误选选项。
四种“分隔”现象
(1)定语从句对主句结构的分隔
The country life he was used to has changed greatly since 1992.
(3)定语从句和先行词的分隔
He was the only person in his office who was invited to the party.
(4)连词和其所连接的分句的分隔

B．where
