问题描述:

怎么分析Jack said it was just what was worrying him most .
what引导的是什么从句

杰克说这这正是当时最困扰他的事情。

jack said 杰克说
it was (just) what was worrying him most
杰克说
那就是最使他烦心的事情
what was worrying him most 这是一句表语从句
这句话有点怪哦。。
我觉得应该是jack said that it was 。。比较完整一点
个人意见……

Jack said it was just what was worrying him most.
“杰克说这就是最让他担心的”.
主语Jack
谓语said
宾语从句it was just what was worrying him most.这又是一个强调句it was ……that/what,what was worrying him most是“最让他担心的”之意.what作主句it was just what was worrying him most的表语,同时作后面从句的主语.
