NONENon-Standard （无词性）【非标准用语】
Am not.
不是
Used also as a contraction for are not, is not, has not, and have not.
也可用作are not，is not，has not 和 have not 的缩略语

The use of ain't as a contraction of am not, are not, is not, has not, and have not has a long history, but ain't has come to be regarded as a mark of illiteracy and has by now acquired such a stigma that it is beyond any possibility of rehabilitation. However, it is used by educated speakers, for example, when they want to strike a jocular or demotic note, as in fixed expressions like Say it ain't so or You ain't just whistling Dixie. · The stigmatization of ain't leaves us with no happy alternative for use in first-person questions. The widely used aren't I?, though illogical, was found acceptable for use in speech by a majority of the Usage Panel in an earlier survey, but in writing there is no acceptable substitute for the admittedly stilted am I not?
ain't 作为 am not，are not，is not，has not 和 have not 的缩略语的用法已有很长的历史， 但是使用ain't 逐渐被认为是文盲的标志，这一坏名声目前为止还没有可能除掉。 然而受过教育的人也使用这个词，例如当他们想达到滑稽或通俗的色彩，如在固定表达Say it ain't so 或 You ain't just whistling Dixie 中。 于是ain't 的坏名声使我们在第一人称问句中没有满意的替代词。 广泛使用的anen't I 尽管不合逻辑，却在早期的调查中却被大多数用法使用小组的成员认为在口语中是可以接受的， 但是在书面语中还没有可以接受的用语来代替公认的不自然用语am I not?

ain't 主要是否定的意思!

它一般没有时态的变化.可以用来代表:
is not,was not,are not, were not, have not,has not 等等!

它属于比较低俗的说法.也就是说,这种用法是在说话者没有受到很高的教育程度时,本人不知道该如何正确使用时态变话时使用的.

一般常见于美国黑人英语中!!

are not 的缩写,很不礼貌，但据说美国一著名的女权主义者说了一句：Ain't I a woman?引起了轩然大波

大声的读出来，你就知道是什么意思了。

口语里很多这种词，如 wanna... ...

are not 的缩写,一般用于非正式环境
