英语翻译 不要机器翻 一句简单的中翻英

You can't go through a second in your life twice.

OR:

Every second(day) in life do not repeat itself

Every day in life is once in a lifetime.

我是意译的，没有直接照字面意思翻译，希望答案对你有用。

None of the single days in the life can be experienced twice.

Every only day in your life can't go through for a second time!

We cannot experience one more time for every single day in our lives.
