whatever引导主语从句时,意义相当于anything that,通常译为“……任何东西（一切事情）”“……所……的一切（所有）”“无论什么……都”.如：
Whatever she says goes.一切她说了算.
Whatever I have is yours.我的东西都是你的.
Whatever she did was right.她做的一切都是对的.
Whatever I have is at your service.我所有的一切都供你使用.
Whatever you want is fine with me.无论你要什么对我都合适.
注意,不要与whatever引导让步状语从句（=no matter what）时的用法相混淆.如：
Whatever happens,I must be calm.不管发生什么事我都要镇静.
Whatever you do,I’ll always love you.不管你干什么,我永远爱你.
Whatever you say,I won’t believe you.不管你说什么,我决不相信你的话.
