2.be about to do/ be on the point of doing…when…

据以下的例子 : when we go to shanghai? when he has gone to shanghai?when had BOB check his students' homework? when did the wife call ALICE?
作为疑问副词，引导特殊疑问句，意思是“什么时候、何时”
when will they come back 他们什么时候能回来
陈述句 we will go home at 7o'clock. (我们将在7点回家)
如果在 7o'clock 下面划线提问，就可以问 when shall we go home? 我们什么时候回家
