英语翻译
Sometimes when I feel low
and things look blue
I wish a boy I had...say one like you.
Someone within my heart to build a throne
Someone who'd never part,to call my own
后两句尤其不懂.看过一个翻译：
心潮低落
愁云笼罩
只盼佳人如卿
相伴左右
待与红颜知己
共筑爱巢
与卿不离不弃
生死相依
但是这个用的是意译.原句到底是什么意思还是不懂.
尤其后两句to build the throne,to call my

我的理解是
当有时候我心情低落,事物看起来低落的时候
我希望有个男孩 像你一样的男孩
某人在我心里有个位置,
某人从来都没分开,就是我自己
再问： 下文 If you were the only girl in the world and I were the only boy! Nothing else would matter in the world today we could go on loving in the same old way! A garden of Eden just made for two with nothing to mar our joy I would say such wonderful things to you there would be such wonderful things to do If you were the only girl in the world and I were the only boy! 可能您的理解有偏差
再答： 你理解一下意译的不就好了，那么追究它干嘛
再问： 我并不是钻牛角尖。只是想下次碰到类似的情况我也能翻译能理解不是更好？ 意译的意境固然美好，然而如何把它同原文中联系起来也很重要。中西文化的差异如何在这翻译中体现，也是我想知道的。 另外，这个意译的版本也未必是正确的。
