-When can I see my grandson,John?
-Don't worry,Granny.He_______be home at any moment.
A.should B.would C.could D.might
为什么不能用could呢

后边是at any moment,就要用肯定的语气了

A.should
这个句子是要安慰奶奶。要用完全肯定的语气。
你如果用might或者could就是可能的语气了,怎么安慰人呢?

should ,由at any moment,得知,在任何时候,她都应该在家的,
must - can - may -should - would - could -might,推测语气 由肯定到不确定,一次减弱

D.might
