题目内容：

一般现在时和一般将来时的问题,高中英语老师进!
语法书上说“在句型I hope,I bet等后面的that分句和句型see(to it)/make sure/make certain+that分句中,可用一般现在时表示将来”.
I hope you have a good time.我希望你玩的很痛快.
但我觉得I hope you will have a good time也是对的?
Make sure that the guests have a good rest.务必使客人们休息好.
好像Make sure that the guests will have a good rest也可以?
I bet it rains tomorrow.我敢打赌明天要下雨
I bet it will rain tomorrow.
