春季高考英语语法专项复习——名词性从句

1、春季高考英语语法专项复习一一名词性从句一、含有从句的句子叫做主从复合句，简称复合句。根据从句在主句中所充当的不同成分，从句分为三种： 名词性从句（主语从句、表语从句、宾语从句）； 形容词性从句（定语从句）；副词性从句（状语从句）二、引导名词性从句的连接词可分为三类：连词：that （无任何词意）；whether, if （"是否"）；以上在从句中不作作成分。连接代词： what, whatever, who, whoever, whom, whose, which, whichever, whomever连接副词： when, where, how, why, whenev
