麻烦翻译一下这首英语小诗,谢谢!
If Ihad one friend left,I'd want it to be you,Someone Who understands me and knows me inside and out,Helps keep me together,belives without doubt,If Ihad one friend left,I'd want it tu be you,When Idream my dreams I dream of you.
Friendship is forever.A friend is forever,The best way to keep your friends is not to give them away.What is onemind in two bodies.What is afriend? A single soul dwelling in two babies, Friendship is love,Without his wings!
请给详细的解释,最好每个词的意思（本意、在这儿的意思）都写出来
（当然像a,the之类的词就不用了）
好的有追分,谢谢!
