英语俚语里gotta和gonna都是什么意思?

1.be gonna = be going to,口语常见用法,注意前面要有be,后面跟动词原形.
Are you gonna be there if I was down?我失意的时候你会在吗?('N Sync:Are You Gonna Be There)
I'm gonna run away and never say goodbye.我要逃掉,不辞而别.(Linkin Park:Runaway)
I am gonna be there at 3:00.我三点时会到那.
(这句话也可以说成,"I am going to be there at 3:00." 或是 "I will be there at 3:00." 也是蛮常用的.此外,老美也喜欢说,"I will catch you there." 例如二个人约好要在体育馆见面,你就可以说,"I'll catch you in the gym.")
2.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.

gotta=got to(a)
gonna=going
吧

gonna
[5^CnE]
<美> 将要(=going to)
gotta
[5^CtE]
<美俚> (=have got to) 必须

gotta:got to (I gotta go now)
gonna:going to (I'm gonna make it)

gonna 等于美国俚语中的 going to 是“将要”的意思
gotta 等于美国俚语中的 have got to 是“必须”的意思
e.g.
I gonna go.
我要走了。
I gotta go.
我必须得走了。

going

gotta =have to go
gonns =going to

gotta=got to(a)
gonna=going
