谁知道一首歌，里面有一句是I know you can，是个女生唱的

是歌手Nicole Renee唱的<<if you believe>>
歌词：If you believe
I know you can
Make it happen for yourself
I can see it in your eyes
It's in your hands
So don't ever stop
This is your destiny
It's meant to be
For you to have|what you want
Hey, baby,|now is your time
For you to win|for you to fly
So let all your dreams|help you succeed
To another way of life|The one you long for inside
The one you thought|you'd never lead
If you believe
I know you can
Make it happen|for yourself
I can see it|in your eyes
It's in your hands|So don't ever stop
This is your destiny|It's meant to be
For you to have|what you want
If you believe|I know you can
Make it happen|for yourself
I can see it in your eyes
It's in your hands|So don't ever stop
This is your destiny|It's meant to be
For you to have|everything you want in love
只不过这首歌不知什么原因，在很多网站都下载不到呢，请暂时在土豆网上听吧，估计再过一段时间就可以下载了。本回答被提问者采纳

也许是《i
can
be
the
one》，试试看。
