从句能用现在进行时或现完吗?

主将从现一定是主句一般将来时,从句用一般现在时

还可都用一般时表必然习惯发生。If a baby is hungry,it cries.(=it will cry.)
主句还可以是祈使句或带情态动词的句子。如:You can't get there on time if you don't hurry up.
Call me when she comes.

这个用在条件状语从句当中意思是:主句用一般将来时,从句从一般现在时举例:I will stay at home,if it rains tomorrow其中I will stay at home是主句 if it rains tomorrow 是从句如果条件状语从句当中的时态不是一...

可以 比如:If you are going out,it's raining now.
还可都用一般时表必然习惯发生。If a baby is hungry,it cries.
If my dog hears any strange sounds,he barks.
If you eat bad plums,you get ill.
If I am happy,I smile.
If you have been walking all night,you need to have a rest.
If you are right,I am wrong.
