Tell what?About what?以及 you say what?是没有这种写法及说法因为也会很彆扭,但如果是一般对话的话,可以这麼说：Say what?或What you say?(是口语里简易的说法之一)或Come again?这句一般是你没听清楚那人在讲什麼...那比如这篇文章告诉我们什么可以是 the passage tell us what ？不可以吧最常见的应该是:What is the passage in this article？也可以这麼说:what does this article tell us about? (about 在句中可有可无)what does this passage tell us about?(about 在句中可有可无)what does the passage tell us?This passage has delivered what message to us?
