2012届高三英语语法专题复习讲义-名词性从句和定语从句【考点点拨】名词性从句可分为主语从句、宾语从句、表语从句和同位语从句。
近几年高考对名词性从句的考查重点如下：【考点1】名词性从句中引导词that与what的使用场合。
1．that 引导名词性从句时，不在从句中充当任何成分，只起连接作用；而wh at是连接代词，在从句中充当成分。

但在介词besides，except，in后可用that引导宾语从句。
在有it作先行词时，that 可用来引导介词后的宾语从句。

高考对定语从句的考查常涉及以下几个方面：【考点6】正确区别限制性定语从句与非限制性定语从句的结构；理解关系代词和关系副词在定语从句中的作用；特别注意指代整个主句内容的关系代词which引导的非限制性定语从句。
