二. 重点、难点：
定语从句及单项选择训练
 
三. 具体内容:
定语从句专讲专练
概念：在含有主句和从句的复合句中，修饰主句中的某一名词或代词的从句叫做定语从句。它所修饰的词叫先行词。定语从句就跟在先行词的后面。用来引导定语从句的词叫关系词，分为关系代词（who, whom, that, which, whose）和关系副词（where, when, why）。
e.g. did you see the person who/that stole it?
this is the pen which/that he is looking for.
上面两例中的先行词分别是the person与the pen，后面是由关系代词who/that; which/that引导的定语从句。
2. 关系代词的选择及功能。
引导定语从句的词有关系代词who, that, which, whom, whose和关系副词where, when, why。它们放在先行词和定语从句之间起联系作用，同时又充当定语从句中的一个成分（如主语或宾语）。有关先行词的选择取决于两点：先行词是人还是物；关系代词在从句中做主语还是宾语。具体用法如下：
1）当先行词是人时，关系代词可以用who或that；当先行词是物时，关系代词可用which或that。
e.g. the film which/that they saw was very interesting.
the boy who/that is sitting in the sun is my brother.
2）当关系代词在句中做宾语时，关系代词可以省略。
e.g. the man （who, whom
