"keep up" 是英语中常用的短语动词,核心含义围绕“维持、延续、不落后”展开,具体用法需结合语境,以下是最常见的义项及示例:
"keep up" 主要表达“使某事物保持原有状态(不下降、不停止、不落后)”,可作及物或不及物动词(常与介词 with 搭配)。
指维持已有的好状态、速度或标准,不降低。
例句:
Keep up the good work!(继续好好干!/保持好状态!)

Keep up your speed—we’re running late for the train.(保持速度,我们赶火车要迟到了。)
强调“不落后于某人/某物”,必须搭配介词 with。
例句:
I can’t keep up with you—you’re walking too fast!(我跟不上你,你走太快了!)
It’s hard to keep up with the latest technology.(跟上最新科技很难。)
She studies every night to keep up with her classmates.(她每晚学习,以免落后于同学。)

1、 keep up with sb./sth.:固定搭配,表“跟上某人/某物”(易错:不要遗漏 with)。
反例:× I can’t keep up you. → √ I can’t keep up with you.
2、 keep up sth.:直接加名词,表“保持/继续某事”(sth. 为具体事物或行为)。
Keep up the music!(继续放音乐!)
3、 区分 keep up 与 catch up:
keep up:强调“持续不落后”(一直跟得上);
catch up:强调“从落后到追上”(之前落后,现在赶上)。
I need to catch up with the class(我得追上班级进度)→ 之前落后;
I can’t keep up with the class(我跟不上班级进度)→ 一直落后。
"keep up" 的核心是“维持现状不变化”,无论是保持状态、跟上进度,还是继续行为,都围绕“不下降、不停止、不落后”展开。结合介词 with 时,重点在“跟上外部对象”;直接加名词时,重点在“维持自身行为/状态”。通过例句代入语境,更容易掌握其用法~
