一时冲动英语

一念之差 a momentary slip一时冲动 on the spur of the moment你可自己参考：

rush1.仓促；匆忙The driver was rushed to casualty after the car accident."车祸后,司机被迅速送到急救室抢救。"2.猛进；猛冲to rush up the stairs 猛冲上楼dash1.突进；飞跑The wolf dashed through the woods. 狼突然跑进树林中。2.猛撞；冲撞The boat was dashed against the rocks. 那船猛地撞到礁石上。

“temporary impulsion”

a moment of impulse

不是dush，应该是dash 和rush的区别，它们是近义词。dash 既是名词又是动词，作名词可以是a race （赛跑）尤其指短跑，如：the 100-meter dash（100米跑）。rush 冲，速度很快地猛烈移动，常有仓促、匆匆忙忙的意思，如：He has a rush of blood. （他一时冲动。）The children rushed out . （孩子们冲了出去。）
