A word spoken is past recalling.
一見鐘情
to fall in love at first sight

Kill two birds with one stone.
一寸光陰一寸金
Time is money.
一失足成千古恨
The error committed on impulse may turn out to be the sorrow of a whole life.
一將功名萬古枯
What millions died that Caesar might be great.
一年之計(jì)在于春，一日之計(jì)在于晨
Plan your year in spring and your day at dawn.
一人難稱百人意
You cannot please everyone.
一氣呵成
Never make two bites of a cherry.

一知半解
A little knowledge is a dangerous thing.
一心一意
John is a person who always works with undivided attention.
一丘之貉
These people are cut from the same cloth./are tarred with the same brush.

一帆風(fēng)順

一刻千金
You have to make good use of time. After all, every time counts.
