4. 定语从句和名词性从句
4.1 定语从句：限制性和非限制性定语从句
引导定语从句
1）关系代词(在定语从句中作主语、宾语、表语）：which, that, who, whom, whose
2）关系副词（在定语从句中作状语）：when, where, why, how
名词性从句：主语从句、宾语从句、表语从句、同位语从句
引导名词性从句：
1）主从连词（不在从句中作任何成分）：that, whether, if
2）连接代词（在从句中作主语、宾语、表语）：what, which, who, whom, whose, whatever, whoever…
3）连接副词（在从句中作状语）：when, where, why, how
4.2 定语从句和同位语从句的区别
active下载定语从句对名词进行修饰限制，而同位语从句阐述的是名词的具体内容。从语法上看，that, which在定语从句中做主语或宾语，而同位语的引导词that不在从句中担任任何成分。
< 1) The story (that) he told me may not be true.定语从句
2) The story that he has made a fortune may not be true.  同位语从句
4.3 什么时候用介词＋which 的形式?
如果定语从句缺主语或宾语，用that/ which 形式。如果定语从句缺状语，用介词+which形式。
< 1) The place which I visited last week is very beautiful.
2) The place in which I used to live is very beautiful.
4.4 which 和as 引导非限制性定语从句
which 和as 都能引导非限制性定语从句，修饰整个一句话。As有“正如”的意思，而which没有。
1) He is easy to get angry, which is well known. 他很容易生气，这一点大家都知道。
2)He is easy to get angry, as everybody knows. 正如大家都知道的那样，他很容易生气。
