it must have been this obvious aimlessness that let me down fall 结构分析,it 是做形式主语吗?请大神分析一下这个句子的结构,语法

这是一个

it is 。。。that。。。结构的强调句型,

简化后可看成:

it is this obvious aimlessness that let me down fall

这是一个表语从句

原型是:this obvious aimlessness let me down fall

回到提问,it must have been this obvious aimlessness是主句,it是主句的形式主语。

供参考
