Question

如题所述

Answer 1

从英语解释上面是很容易区分的
command- have authoritative or peremptory order;dominate from a superior height. 指的是命令,自上而下，有强制的意味。
request-politely or formally ask for 是礼貌的，较为正式的请求。
require-if you are required to do something or someone requires you to do it, you have to do it because it is a rule or someone insist that you do it. 被要求，必须
demand-if you demand something, you ask for it very forcifully. 非常强硬的要求本回答被提问者和网友采纳
