我想知道We can't remember the past 到底是记得还是不能忘记呢？是从前还是过去呢？

I lost a book…l can't remembe now的意思 我想知道We can't remember the past 到底是记得还是不能忘记呢？是从前还是过去呢？ we can't live without air or water,can we?应该答什么希望知道的叔叔阿姨帮帮忙吧! we can't find it We can't help crying. We can't change the We can’t afford not but,we can't stay with you forever让我知道这句话的正确意思 we eat what we can and what we can't we can这句话怎么翻? they can't sing.We can't sing neither.还是We can't sing either. We can't arrive late for class能改写成We don't arrive late for class吗?我不知道怎么用can't和don't那能不能改写？ 英文can‘t的用法句子：We cannot overemphasize the importance of learning a foreign language.翻译为：我们无论怎么强调学外语的重要性也不过分.我知道can not 是有这样的用法,但是我想知道,什么情况下翻译 love is more beautiful than fairy tales,but regetfully,by no means we can li我想知道中文 ——（ ）to bring the book here tomorrow moring.I want to use it.（答案为C.)——Don’t worry.I won’t.A.Forget B.Remember C.Don’t forget我想问“Remember和“Don’t forget”不是一样的吗?please~ 英语翻译we can't live on air. in the museum,we can't take we can't live without water we can't live without(没有) a____
