与这个时态连用的时间状语常用：
tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般将来时态与其它结构表将来情况的区别：
一般将来时态 ：主要从时间的角度表将要发生的动作或情况。
be going to 结构 ：①表（主观上）打算或准备做某事时。 ②表有发生某事的预兆时。
e.g. They are going to have a competition with us in studies. It is going to rain.
据以上区别，故下面一句是错的：
I am going to be eighteen years old next year.
应改为： I shall be eighteen years old next year.
be about to do sth 结构 ：意为"刚要做某事"、"马上要做某事"强调时间之紧迫性。
