英语翻译.我离不开你.也许.._____________________________帮我翻译这段话..不要在线翻译..要会英文的都来...还要解释下..为什么要这样写这些英文.

You are so important to me that I cannot live without you. But, perhaps, you even have no idea of it.
这就是直译。用简单的单词构成复合句，既真诚又得体

You mean much to me that i can not bear myself from you,which you haven't noticed.

You means everything to me, I can not breath without you.
Maybe.. you do not even notice that..
你对我意味着一切，没有你我不能呼吸。
也许..你甚至不知道..

you are the most important person in my heart或者简单点 you are very important to me

You are very important to me.I can't be without you.
Maybe,you don't know.
其实为什么要这样写很简单,这样是对的,而且很符合原文的意思.如果你有不明白的地方,可以在百度Hi上给我留言,但我只能在晚上回复你.
自己翻译的,希望答案对你有用.

Maybe you don't know you are indispensable to me and I cannot live without you!
Explanations: A be indispensable to B.. 是A对B不可或缺的意思。
