In fact, in linguistics, we talk about " language variety" – the different kinds of language that's used in different situations.

事实上，在语言学中，我们谈论“语言多样性” ——在不同情况下使用的不同种类的语言。

However, there are also varieties of language, varieties of English that you will hear in songs or on television that are called " nonstandard." But they're still perfectly acceptable within those situations.

然而，也有各种各样的语言，你会在歌曲或电视上听到的各种英语被称为“非标准” 。 但在这些情况下它们仍然是完全可以接受的。
