‎2018届二轮复习 名词性从句讲与练 一、what与that引导名词性从句的区别 ‎1.what 引导名词性从句时，意为“什么”，在从句中作主语、宾语和表语。‎ ‎ What was the most important to her， she told me， was her family.‎ 她告诉我，对她来说最重要的是她的家庭。‎ ‎ China is no longer what she used to be.‎ 中国再也不是从前的中国了。‎ ‎2.that引导名词性从句，不充当任何句子成分，只起连接作用，无任何意义；引导主语从句时，常用it作形式主语，谓语动词用单数；引导宾语从句时，that常被省略。‎ ‎ That she will succeed is certain.＝It is certain that she will succeed.‎ 她一定会成功。‎ ‎ It is obvious to the students that they should get well prepared for their future.‎ 应该为将来做好准备，这一点学生们相当清楚。‎ 二、 同位语从句 ‎1.同位语从句常放在fact， news， idea， truth， hope， problem， information， belief， thought， doubt等抽象名词的后面，是对前面的名词作进一步的解释，说明前面名词的具体含义。‎ ‎ The hope that he may recover is not gone yet.‎ 他恢复的希望还没有破灭。‎ ‎ The problem whether we should continue to do the experiment has been solved.
