He was ill ._was why he didn't attend the meeting A.It B.This C.That 选C,求详解

问题描述:

He was ill ._was why he didn't attend the meeting A.It B.This C.That 选C,求详解

it 通常指前文提到过的“同一”物体(必须是同一个)
this 通常指“这个”
that 可以指前文提到过的某种情况It 作形式主语时候的句型多为强调句,在这里也似乎说的通,为什么不选it?强调句是It is/was +被强调的部分+that+(指人可用who)+其它 我有点忘了强调句了。。。这个应该差不多吧。。
