关于can,条件状语从句

We can walk there if we can't find a bus. 在这句中，主句是一般性将来时么 还是说can在这里表示将来？

can用的是现在时形式，can表示说话人的“情感态度”

呵呵！你要听好哦。 条件状语从句主将从现你知道吧!其中的这个主将既包括将来时也包阔情态动词

if ,unless ,so/as long as on condition that 等等引导的从句一般为条件状语从句.例如. 1.if you can answer my question in two minutes ,i'll give you a prize. 2.so long as you put your heart into your study ,you can succeed. 3.i'll not help you ,unless you tell me the truth. 4.we can get a lot of information if we surf the internet. 5.she can come here on condition that you invite her ahead of time.
