当我们谈论时间的表达时,"at a time"通常表示曾经的某一次,强调的是某个特定的过去时刻。这个短语暗示着某个具体的动作或事件发生过一次。例如,你可以说:"I solve a problem at a time, breaking it down into manageable parts."
"At times"则表示时常,意味着某行为或情况会周期性地出现或发生,不一定局限于过去的某个特定时间。例如,"She feels stressed at times e to her busy schele."
"At one time"意为曾经,指的是某事在过去的某个阶段发生过,但可能现在已经不复存在或改变了。例如,"He used to play the piano at one time, but now he focuses on painting."
"Sometime"这个词既可以指将来的某个不确定时刻,也可以指过去的某个不确定时刻。它不强调即时性,而是一个模糊的时间概念。例如,"I'll meet you sometime this week, either tomorrow or the day after."
"Sometimes"则表示偶尔或不经常,指的是某行为或情况在某些情况下发生,不是一贯的常规。例如,"They celebrate their birthdays sometimes, but not every year."
