一句英语（if引导的条件句）
It's OK if you're not on time.
1.我印像中if引导的条件句不是从句用一般现在时,主句用一般将来时吗?
比如：
If it doesn't rain,I will go there tomorrow.
2.这句可以改为It will be OK if you're not on time.
答
1.是口语中不太正规的说法,但可以接受.
2.这句可以改为It will be OK if you're not on time.
3.主将从现规则还有一种变形：主句是含有情态动词如can的一般现在时表一般将来时,从句仍然用一般一般现在时表一般将来时.
