Answer 1

他的爱她都知道 她都明白 她都了解

[这是Bruno mars的all she knows]
歌词：
Once again you're home alone 曾经你一次又一次的独自一人在家

Tears running from your eyes 泪水流滚出你的眼眸

And I'm on the outside 而我却在外

Knowing that you're all I want 要知道你是我的全部

But I can't do anything 但是我却无能为力

I'm so helpless baby 我是多么的无助 亲爱的

Everyday same old things 每一天重复着过去的事情

So you're still feelin pain 你依然感觉那份痛楚

Never had real love before 从前都没有拥有过真爱

And it ain't her fault 但是这不是她的错

She knows better but 她知道有更好的 但

She can't help it 她却情不自禁

Wanna tell her 想告诉她

But would that be selfish 但是这样是一种自私

How do you heal 你是怎样治愈

A heart that can't feel, it's broken一颗没有感觉的心，它伤碎了…

His love is all she knows, all she knows, all she knows 他的爱她都知道 她都明白 她都了解

You've been livin this way so long 你都这样生活了这么久

And it's killing me 这犹如杀了我

Cause you can have so much more 原因可以有如此多

I'm the one you're looking for 我是你唯一寻找的

But you close your eyes on me 但是你在我面前闭上了眼

So you still can't see 所以你仍然看不见我
