题目内容

5．-I don't know if Sam ______ tomorrow．
-Don't worry．I will tell you as soon as he ______．（　　）

	A．	comes； will come		B．	will come； comes
	C．	will come； will come

分析 -我不知道Sam明天是否会回来．
-别担心，他一回来我就告诉你．

解答 if引导宾语从句，主句是一般现在时，从句用本来的时态，故第一个空该填will come．as soon as作为连词，引导条件状语从句，它表示的意思是"一…就…"．在复合句中如果主句用将来时，则状语从句用一般现在时．故选：B．

点评 if是题目中出现频率很高的连词，并且它的用法也很多．因而要特别了解其用法及其语法功能．
