知识点三一般将来时
【知识梳理】
(1)一般将来时的结构
① will+动词原形，常与表示将来的时间状语连用。

如：
e.g. I will meet you at the school gate tomorrow.明天早上我将在校门口见你。

②be going to+动词原形表示将来发生的动作或存在的状态，主语一般是人。

如：
e.g. I am going to be 15 next week. 下周我就15岁了。

③will 和be going to 的区别
be going to与will两者都可表示将要发生的事、将要去做某事，但它们有如下几点区别：A. be going to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些，如：
e.g. He is going to write a letter tonight.
He will write a book one day.
B. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。

e.g. He is seriously ill. He is going to die.
C. be going to 含有“计划，准备”的意思，而will 则没有这个意思，如：
e.g. She is going to have a trip.
He will be here in half an hour.
④在有条件从句的主句中，一般不用 be going to, 而多用will, 如：
e.g. If any beasts come at you, I'll stay with you and help you.。
