Cathy wonders if her teacher _______ to her house. If she _______, what will she say to her parents?

A.comes, comes

B.will come, will come

C.comes, will come

D.will come, comes

答案

D  

if既可以引导宾语从句又可以引导状语从句。if充当宾语从句的连接词时,相当于whether,词义为“是否”,遵循宾语从句的时态规则,可根据语境选择任何时态;充当从属连词,引导条件状语从句时,词义为“如果”,若主句中的谓语动词用一般将来时,则从句中的谓语动词通常用一般现在时表示将来。
