初中英语主动8种时态集中练（题的答案）
If it __(rain)tomorrow,I'll go by car.
I don't know if she___(tell)me when she ____(arrive)
答
rains
will tell arrives
答
rains 第一个If是如果的意思，这是条件状语从句，主句用将来式，从句（即以If引导的条件状语从句）用一般现在式。
will tell arrives
这句中的If意为是否，前面用将来式，后面做宾语从句用三单形式。
答
第一句主句是将来时,所以从句是现在时,填rains,符合主将从现；
第二句if表示是否,后面跟从句,所以用will tell和arrives.
答
If it _rains_(rain)tomorrow,I'll go by car.
I don't know if she_will tell_(tell)me when she _arrives_(arrive)
