一次湖南一所中学学生去国外夏令营回来在湖南卫视天天向上合唱的一首英文歌叫什么歌词有『警察医生』这些

名字是：
Be What U Wanner Be
歌词如下：
doctor（医生）, actor, lawyer or a singer
why not president, be a dreamer
you can be just the one you wanna be
police man（警察）, fire fighter or a post man
why not something like your old man
you can be just the one you wanna be
driver, actor, lawyer or a singer
why not president, be a dreamer
you can be just the one you wanna be
i know that we all got one thing
that we all share together
we got that one nice dream
we live for
you never know what life could bring
coz nothing last for ever
just hold on to the team
you play for
i know you could reach the top
make sure that you wont stop
be the one that you wanna be
now sing this with me
we may have different ways to think
but it doesnt really matter
we all caught up in the steam
of this life
focus on every little thing
thats what does real
