on the point of/at the point of/be about to的详细区别 短语on the point ofat the point ofbe about to的详细区别不要字典上的翻译,要他们的详细用法真诚的向资深的老师请教,
一、为了说明这三个短语的意思,先得从将来时态说起.
六大类表示将来的办法：
1. will/shall —— 表示可能性的将来,如：
I shall leave for Shanghai. 我有可能去上海.
He will tell me all about it. 他有可能把一切都告诉我.

2. be going to —— 表示主观在将来的打算或主观对客观的判断
I am going to visit the expo this week. 我打算本州参观世博会.
It is going to rain tomorrow. 明天就要下午了.
3. 一般现在时 —— 表示不会改变的将来
The train leaves at eight. 火车八点开.
Tomorrow is Tuesday. 明天是星期二.
4. 现在进行时 —— 表示正在着手准备的将来
I am leaving for Shanghai tomorrow. 我正准备明天到上海.
It is getting dark. 天就要黑了.
5. be to —— 表示约定好的将来
The meeting is to be held this afternoon. 会议定于今天下午召开.
We are to get married on Sunday. 我们定于星期日结婚.
6. 呼之欲出的将来可以用以下方式表示
* be about to 等 ——正打算/差不多
The job is about done. 工作差不多要完成了.
He was about to leave when his father came back. 他几乎就要离开,这时候父亲突然回来了.
* on the point to —— 马上就,正要（可以替换上面例句中的 about to）

二、几个短语的区别、
1. be about to 相当于时态助词,后面只能跟动词原形,表示将来.
2. on the point of 中的 of 是介词,后面跟名词或者动名词,表达的意思与 on the point to, 但是不含将来的意思,不能与谓语动连用作时态助词,只能用作时间状语,如：
On the point of leaving, his father came back.（比较上面的例句）
On the poit of finishing the job, the boss informed him to go to an interview. 就在快要干完那家工作的时候,老板通知他去参加一次接见.
3. at the point of 中 of 同样是介词,也不表示将来,与 on the point of 不同的是既可以用作地点状语或也可以用作时间状语,后面一般跟名词,意思是“靠近/接近某处或某时”,如：
The troops halted at a point of the river. 部队在靠近河约地方停了下来.
We arrived at the city at the point of evening. 我们在傍晚时分到达了那个城市.

at the point of与“on the point of的区别.请举例说明 on the point of和at the point的区别是啥呢? on the point of 用法呢?
