we are the world 给的歌词和唱的不一样？

我英文不好，但我怎么都对不上歌词，难道发音有这么大的差别？
问一下，MJ这首歌为什么歌词和唱出来的不一样！
WE ARE THE WORLD -- Michael Jackson & Lionel Richie
There comes a time when we heed a certain cal
When the world must come together as one
There are people dying
And it's time to lend a hand to life
The greatest gift of all
We can't go on pretending day by day
That someone, somewhere will soon make a change
We are all a part of God's great big family
And the truth, you know, love is all we need
We are the world, we are the children
We are the ones who make a brighter day so let's start giving
There's a choice we're making We're saving our own lives
It's true we'll make a better day, Just you and me
Send them your heart so they'll know that someone cares
And their lives will be stronger and free
As God has shown us by turning stones to bread
So we all must lend a helping hand
We
