问题描述:

noon的前面用什么介词?
In on at for?四个当中选择一个!

英语中【at】的用法:
(1)在某具体时刻之前,如at seven o'clock,at 7:30。
(2)在固定短语中,如:at noon,at night,at that time,at the age of, at the weekend,at Christmas。

at

at noon
by noon
是情况而定,语言没有绝对!
noon [nu:n]
n. 正午,中午
例句:
It's my habit to take a nap at noon.
我有个睡午觉的习惯。
He reasoned that if we started at dawn, we would be there by noon.
他推断, 我们要是黎明出发, 中午就能到.

用at
绝对的

At noon只有这才是正确的搭配
