comeupwith和catchupwith的区别？
come up with 提出；想出；赶上
1. 赶上；接近，走近：I came up with them as they were rounding the corner.他们正在拐弯时，我赶上了他们。
2. 提出，提议：We werent able to come up with any new suggestions.我们提不出任何新建议。catch up with 赶上，追上；逮捕；处罚 这两个词作为【赶上】，意义很接近，有时完全可以替换。仅有的区别是：come up with 表达的动作一般比较缓和或缓慢，不急促，强调【在位置上接近、靠近】；catch up with 表达的动作通常更为激烈或匆忙，突出【急促、含有追赶】之意。 祝你学习进步，时时开心！O(∩_∩)O~~
