He doesnt know if he should bring a present. 用法：1）此处if 表示“是否”，相当于 whether ，引导宾语从句。2)should 此处表示“ 应当”，不是用来表示虚拟语气。拓展：if 作“是否”讲，引导宾语从句，从句可以用一般将来时或其他时态。 if 作“假设”讲，引导条件状语从句，从句用一般如今时代替一般将来时。（翻译）1) I dont know if I should go to the party. _2) He doesnt know if we will arrive on time tomorrow morning._3) If I have enough money next year, I will go to England.3. I dont have a present , what if everyone else brings a present ?_用法：what if 表示“假设，怎么办？要是又怎样？”相当于What would happen if ?
