一、whatever的用法Whatever有两个用法，一是引导名词性从句（如主语从句、宾语从句、表语从句），二是用于引导让步状语从句。1. 用于引导名词性从句Whatever she did was right. 她做的一切都是对的。Whatever she did was right. 她做的一切都是对的。I will do whatever you wish. 我可做任何你想我做的事。Give them whatever they desire. 他们想要什么就给他们什么。Whatever I have is at your service. 我所有的一切都由你使用。You may do whatever you want to do. 无论你想做什么事，你都可以做。I’ll just say whatever comes into my head. 一我想到什么就说什么。One should stick to whatever one has begun. 开始了的事就要坚持下去。She would tell him whatever news she got. 她得到的任何消息都会告诉他。 I’m going to learn whatever my tutor wishes. 我将学习任何我的导师愿意我学的东西。College students are seen doing whatever work they can find. 我们可以看到,只要有工作，大学生们什么都干。 Do whatever she tells you and you'll have peace. 她叫你干什么你就干什么,那你就太平了。2. 用于引导让步状语从句Whatever we said, he'd disagree. 无论我们说什么，他都不同意。Whatever happened I must be calm. 不管发生什么情况我都要镇静。不管发生什么情况我都要镇静。We’ll go along together whatever happens. 不管发生什么情况我们都要起干。Don’t lose heart whatever difficulties you meet. 不管遇到什么困难都不要灰心。Whatever you do, I won't tell you my secret. 不管你做什么，我都不会把我的秘密告诉你。Whatever happens, we'll meet here tonight. 不管发生什么事情，我们今晚都在这儿碰头。Whatever happens, the first important thing is to keep cool. 不管发生什么事,头等重要的是保持冷静。【注意1】whatever还可用于加强语气，相当于what ever, what on earth等。如：what ever, what on earthWhatever is the matter? 这是怎么回事?Whatever does he mean? 他到底是什么意思?【注意2】WhateverWhatever从句有时可以省略。如：Whatever your argument, I shall hold to my decision. 不管你怎样争辩，我还是坚持自己的决定。 

二、no matter what的用法
No matter what只能引导让步状语从句（不能引导名词性从句），其意为“无论什么”。如：No matter what happened, he would not say a word. 不管发生什么情况，他一句话都不肯讲。No matter what you do, don’t touch this switch.  无论怎样，都别碰这个按钮。No matter what happens I’ll stand by you.  不管发生什么事我都支持你，别怕。She says she’11 follow him no matter what he says. 她说不论他怎么说她都要跟他走。He will continue the work no matter what happens. 不管发生什么情况他都要继续这项工作。【注意1】这样用的no matter what与引导状语从句的whatever用法相同，有时可互换。如：No matter what you say, I believe you. =Whatever you say, I believe you.  无论你说什么，我都相信你。【注意2】有时no matter what引起的从句中动词会被省略。如：I’ve decided to leave tomorrow, no matter what (happens). 不管发生什么情况，我已决定明天走。In our company, every body is well taken care of, no matter what his position (is). 在我们公司，每个人都得到很好的照顾，不管他地位如何。
