1.Tell Mary we'll be late for dinner this evening. 你告诉玛丽，今晚吃饭我们将晚到一会儿。

　　句中 we will be late…是一个宾语从句，作动词 tell的宾语。

　　这个宾语从句省略了引导词that。late表示“迟到”的意思时通常作表语，与for连用。

　　2.by the way, 顺便(问、说一下)。

　　说话者忽然想到另一件事的时候用此来表示改变话题。

　　宾语从句(2)

　　在以前已介绍过宾语从句一般由that, which和whom引导，它们有时在口语中可以省略。除此之外，宾语从句还可以由when, where, what, why, how以及 if和 whether这些疑问词来引导，而它们在句中往往不能加以省略。无论是that, if还是wh-疑问词引导的宾语从句通常都应以陈述句的形式出现。

　　请看例句：

　　She wants to know when you'll have a bath.
