问题描述：
英语：“逆水行舟,不进则退”,怎么说?
请问这句话如何翻译成英语,我先抛砖引玉：The assault with navigate ,can't forward will recoil.
请使用有独立主格的结构；结构越简单越好。
答
Learning is like rowing a boat upstream,either you paddle hard to move forward or you get flushed away.
Learning is like rowing upstream | not to advance is to drop back
Learning is like canoeing against the current,one falls back if he does not try to go forward第二句简单明朗，我喜欢。能不能再用独立主格的结构写一句？Our learning is like rowing upstream, not to advance is to drop back.
