答案
你看错了吧,在when和if引导的从句里,恰恰应该用现在时表将来.你看If it is fine tomorrow,不正是用现在时表将来吗?
中学英语中,有些从句只能用一般现在时形式表示一般将来时,现归纳如下,以供参考.
在由if,unless引导的条件状语从句中,如:1.If it doesn't rain tomorrow,there will be a sports meet in our school.2.You will miss the train unless you set out at once.
在由when,before,after,as soon as,once,till/untill引导的时间状语从句中,如:1.When you meet a new word,you may look it up in your dictionary.2.When you arrive in London at 8 tomorrow morning,it will be 4 o'clock in Bejing in the afternoon.3.You will have to get everything ready for the party before I come this evening.4.After you finish reading the whole book,you will be able to know its real meaning.5.I'll write to you as soon as I get there.6.Once you understand its meaning,you will easily remember the word.7.I'll not leave here until/till he comes back.
在由as/so long as(只要……)引导的条件的状语从句中,如:
It is hard to avoid mistakes,as/so long as you correct them conscientiously,it will be all right.
