pr剪辑按键:问一个语法

来源:百度文库 编辑:查人人中国名人网 时间:2024/04/28 03:53:08
请问究竟是
at the point of doing sth
还是
on the point of doing sth?
我在两本语法书上面看到为什么不一样?

2种用法都可以.

at the point of = just before/即将,临近
如, at the point of death/临终

on the point of = just starting to; just about to 即将...之时,正要...的时候
如, on the point of leaving home/ 正要离家时

at the point of doing sth 是接近于做某事

on the point of doing sth? 是正要做某事

on the point of doing sth
just about to do sth
I was on the point of going to bed when you rang.你来电话时我正要睡觉.

两上都对看你需要哪个意思
at the point of doing sth 靠近做某事
on the point of doing sth? 正要做某事

on the point of doing sth.正要...的时候

at the point of doing sth
