题目

What he really means is that he disagrees with us.这一句是主语从句还是表语从句?主句是什么?
What he really means是这个句子的主语,that he disagrees with us是这个句子的表语,所以不清楚是主语从句还是表语从句.

答案

What he really means【主语（What引导的主语从句）】
is 【系动词】
that he disagrees with us【表语（that引导的表语从句）】
句子为 主系表 结构
主语从句分析：What he really means
从句充当主语,由连接词what引导,并且在从句中充当【mean的宾语】
即为：he really means What
表语从句分析：that he disagrees with us
从句充当表语,由从属连词that引导,that无实际意义,在从句中不充当任何,仅是连接作用
表语从句句型：be+表语从句
