如without…,but for…(要不是因为...; 如果没有...);
with...(如果有... 的话);otherwise, or( 否则...);等。

If I were a boy
Even just for one day
I'd roll out of bed in the morning
And throw on
What I wanted and go
Drink beer with the guys
And chase after girls
I'd kick it with who I wanted
And I'd never get confronted for it
Because they'd stick up for me
If I were a boy
If I were a boy
I think I could understand
How it feels to love a girl
I swear I'd be a better man
I'd listen to her
Cause I know how it hurts
When you lose the one you wanted
Cause he's taken you for granted
And everything you had
Got destroyed
If I were a boy
If I were a boy
I would turn off my phone
Tell everyone it's broken
So they think that
I was sleeping alone
I'd put myself first
And make the rules as I go
Cause I know that
She'd be faithful
Waiting for me to come home
To come home
If I were a boy
If I were a boy
I think I could understand
How it feels to love a girl
I swear I'd be a better man
I'd listen to her
Cause I know how it hurts
When you lose the one you wanted
Cause he's taken you for granted
And everything you had
Got destroyed
If I were a boy
It's a little too late
For you to come back
Say it's just a mistake
Think I forgive you like that
If you thought
I would wait for you
You thought wrong
But you're just a boy
You don't understand
Yeah... you don't understand
If I were a boy
How it feels to love a girl
Someday you'll wish
You were a better man
You don't listen to her
You don't care
How it hurts
If I were a boy
Until you lose the one you wanted
Cause you've taken her for granted
You lose the one you wanted
You've taken her for granted
You lose the one you wanted
You've taken her for granted
And everything you had
Got destroyed
But you're just a boyThank you
