问题描述:
My mother will take me to the movie if she _________ free this weekend.
My mother will take me to the movie if she _________ free this weekend.
A.is B.will be C.was D.would be
A.为什么不能是B,这个句子不是表示将来吗,如果选D又怎么解释呢,为什么D不可以.
答
条件状语从句:记住条件从句为一般现在时,主句则为一般将来时.
此题中my mother will take me to the movie是主句,时态为一般将来时,则从句一定为一般现在时,也就是if后面的句子时态为一般现在时,所以选A
would be 中would 是will过去式,更不能选了
