雅思阅读语法名词性从句

Clauses）。名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。引导名词性从句的连接词引导名词性从句的连接词可分为三类：连接词：that、whether、if不充当从句的任何成分）连接代词：what、whatever、who、whoever、whom、whose、which.连接副词：when、where、how、why不可省略的连词：介词后的连词引导主语从句和同位语从句的连词不可省略。例如：That

won.我们听到消息说我们队赢了。比较：whether与if均为"是否"的意思。但在下列情况下，whether不能被if取代：whether引导主语从句并在句首引导表语从句whether从句作介词宾语从句后有"or

not"大部分连接词引导的主语从句都可以置于句末，用it充当形式主语。例如：It

not

important

who

will

go.谁去，这不重要。It

is
