some day与one dau，前者只表将来，后者既可以表过去又可以表将来。【但该如何记忆】

Question

如题所述

Answer 1

可以用例句来记忆❤️
someday 副词，有一天＝some day 只能用于将来时态（一般将来和过去将来）

Someday, you will realize that it is a waste of money.

people might have to migrate there someday.

oneday＝one day 有一天 ，终有一天 可以用于过去时也可以用于将来时。one day 更为常见一些

When he was delightfully wandering through the woods oneday，……

I hope oneday I can live the life the same way ... ...

One day, he bought a fish and took it home

Answer 2

就用中文记

some day就是某一天，中文里都说"也许将来的某一天。。。"

one day就是一天，中文一般就是"一天，我。。。"或者"也许，有一天我会。。。"
