在英语中,"to worry about" 或 "to be concerned about" 可用来表示担心某事。例如:

I'm worried about the weather for tomorrow's hike. (我担心明天徒步旅行的天气。)
She's concerned about her grades. (她担心她的成绩。)

"Worry" 和 "concern" 都有担心的意思,但 "worry" 多指个人的烦恼或担心,而 "concern" 则指对事情本身的关注或关心。

"Worry" 和 "concern" 都是英语中常用的单词,并不是特定的俚语或俗语。

例如:

Don't worry about it. (不要担心。)
His health concerns me. (他的健康让我担心。)
