问题补充：
be about to 和be going to 有什么不同?请详细回答.举出例子最好.感激不尽
答案：
about to 和 be going to 的区别
be about to 和 be going to 都有未来的含义.
1.be about to 侧重“即将...,就要...”( = be on the point of ...ing),
be going to 指“不久的将来”( = near future).
2.be about to 是文语,be going to 是口语.
3.be about to 不能接时间状语,be going to 可以接时间状语.
（错）I am about to go next week.应改为“I am about to go.”
======以下答案可供参考======
供参考答案1:
be about to[+ v.]（比be going to + v.急迫；不可和tomorrow等表示将来的副词连用）即将：We were ～ to start,when it rained.我们正要出发，这时下雨了。
供参考答案2:
be about to 后不能接具体时间，表”某一时刻正要做某事”；
be going to 可以接具体时间，表“计划做某事”。
例子：I was about to leave when it rained.我正要离开时天下雨了。
Im going to visit Tom next Monday.下星期一我要去拜访汤姆．
