请教有关quite certain,might just,can be疑问
1.I am quite certain.是“很确定,很有把握”的意思吗?
2.might just 是“可能”的意思吗?A:I wonder who sent these to me.
B:It (could possibly )be John.那么这里为什么不能用might just?
3.I suppose he (could be) about five years old.请问这里的“可能”为什么要用过去时（could）,为什么不用“can be可能”?（我想既然有can not ,那么也肯定有can be吧,难道只有“could be可能”的说法,没有can be的用法吗?）

1.对.
2.B:因为是已经发生的事情,而且猜测是可能性比较大.
3.虚拟语气,必需用could be
