catch up和catch up with有什么区别么？这里能去掉with么？
推荐回答（1个）
Catch-up 在口语里一般指聊聊天叙叙旧。如lets go grab some coffee and catch up for a while.或者是追赶上某过程。如：now im falling far behind, i have to catch up!Catch up with 后面就得加人，且with 不能省，这是个固定短语。
keep up with和catch up with 都有赶上某人，使自己不落后 的意思，但前者注重保持此时状态，而后者注重超越此时状态而赶上别人。
eg.Your English is terrible ,if you do not work hard,you will not catch up with others. eg.I must work hard ,or I will not keep up with my classmates.
