一、gotta的用法二、get to和got to的区别

gotta=got to (相当于have to 不得不,必须)
There's something I gotta tell ya我有点事要和你说.
I've gotta get outta here.我得离开这儿了.
I've gotta catch the bus.我要去赶公共汽车了.
A man's gotta look out for his family.
= A man has got to look out for his family.
都是 "has got to" 这个句型,因此短写成 's gotta.
got to 是get to 的过去式
