西域男孩的歌《if》里的歌词大意?

  If 
If a picture paints a thousand words, 
then why can't I paint you? 
The words will never show the you I've come to know。
   
If a face could launch a thousand ships, 
then where am I to go? 
There's no one home but you, 
you're all that's left me to。
   
And when my love for life is running dry, 
you come and pour yourself on me。 
If a man could be two places at one time, 
I'd be with you。
   
Tomorrow and today, 
beside you all the way。 
If the world should stop revolving spinning slowly down to die, 
I'd spend the end with you。
   
And when the world was through, 
Then one by one the stars would all go out, 
then you and I would simply fly away。
   
如果(爱的假设) 
如果画纸能画出万语千言， 
为何我不能画出你的容颜? 
千言万语也不能表达你已知道的事情。 
如果笑脸能笑对千条小舟， 
你可知我该何去何从? 
唯有你在我们的爱巢， 
你是我所遗失的一切。
   
当我生命的爱河日趋干涸， 
你为我带来爱的甘露。 
如果人能身居两处， 
我将一直陪你。 
明天与今天， 
没有你我心无挂碍。
   
如果世界停止转动， 
我会与你共度末日。 
当昼夜开始交替， 
晨星依次跃然碧空之上， 
你与我将携手天际。
