其实收心可以理解为认真,“收收心吧!”可以说“认真一点吧!”就是“be carefully”了
收心就是集中注意的意思啊
一般说
concentrate on /focus on more serious things
既然言归正传可以用get down to business,那么收心pull your heart back to business(正事儿) ,这是比较口语的说法
1. Concentrate on more serious things
2. Have a change of mind
3. Back to the original status
keep your mind
