哪些状语从句中应用一般现在时代替将来时

你说的是不是可能将来发生的事,在状语从句中用了一般现在时?
我可以举几个例子(注意:不是所有的句子都是这样!)
1)时间状语从句
当时间状语从句表示将来意义的时候,主句可以用一般将来时(有的可以用现在完成时).eg
After she finishes/has finished homework,she can play computer games.
As soon as he returns,I'll tell him.
I'll go home when she arrives.
2)条件状语从句
If he comes,I'll tell him the truth.
If it doesn't rain,we'll play basketball.
和时间状语从句一样,从句在主句用一般将来时时还是用一般现在时.
