Students who speak in a minority dialect, such as African-American English, are often disparaged for having a poor grasp of standard English grammar.

讲少数民族方言（例如非裔美国人英语）的学生经常因对标准英语语法掌握不佳而受到贬低。

Okay, so one thing I want to mention is: If you look up this subject in a standard grammar textbook or even online, usually they just divide these verbs into two: Dynamic and stative.

好的， 所以我想提一件事：如果你在标准语法教科书甚至网上查找这个主题，通常他们只是将这些动词分为两类：动态和静态。

And then back to the standard grammar again now, going to the past tense, so: " Was not" becomes " Wasn't" , " Wasn't" , and " Were not" becomes " Weren't" , " Weren't" .

然后现在又回到标准语法， 回到过去时，所以：“Was not” 变成“Wasn't” ，“Wasn't” ，“Were not” 变成“Weren't” ，“Weren'吨” 。
