6._____ she had forgotten to take her notebook.

问题描述:

6._____ she had forgotten to take her notebook.
6._____ she had forgotten to take her notebook.
A.That occurred to her B.She occurred that
C.To her that occurred D.It occurred to her that

D it 作形式主语能给详细一点的解析吗?解释一下为什么不选其他的呢that引导的主语从句,为了是句子平衡,避免头重脚轻,常用it作形式主语,把从句放在主语后面That she had forgotten to take her notebook occurred to her.变型后就是It 主句that 从句老师上课应该讲的很清楚了
