request和require在法律文件中，均可用来表示“要求”，但是表示“请求”，常用“request”。对于request和require，在《元照英美法词典》中分别给出了如下的释义：

request 请求，要求

尤指请求债务的偿付或合同的履行。有时与「command」同义，如具有权威的人提出「要求」，只是一种婉转说法，实质上是以一种平和的方式下达的「命令」。

require 需要；要求；命令

该词源于拉丁文「requiro」，意指求取。该词虽然无疑有「需要」的含义，但这并非是它的主要或一般性含义。一般认为，该词最重要的义项应为「依权利要求」、「依授权命令」。

简单来说，request （sb to do sth） 是“请求（某人做某事）”，是下对上的要求；Require 表示order, demand, 是“命令，要求”之意，指上对下的要求，比如法律条款对当事人的要求，业主对雇员的要求。
