为什么不说中文。用英语怎么翻译

为什么不说中文？

英文翻译：

• Why not speak Chinese?

• Why don't you speak Chinese?

• Could you speak Chinese?
  

重点词汇解释：

• why

used in questions to ask the reason for or purpose of sth

（用于问句）为什么，为何

• speak

(not used in the progressive tenses 不用于进行时) to be able to use a particular language

会说，会讲（某种语言）

• could

used to politely ask sb to do sth for you

（礼貌地请求别人做事）能，可以

Why don't you speak Chinese?
更标准的说法是：
Why not speak Chinese?

Why not speak Chinese?或Why don't you speak Chinese?都可以，不过后者强调的是“you”。
希望对你有所帮助。

Why don't you speak Chinese?比较正式的说法，why not 更口语，关系更亲近的人之间说。不正式。不是问句，倾向于倡议，让我们讲汉语吧。

Why not say Chinese?
