全体同学都要准时参加明天举行的会议(request)英语翻译

All students must attend on the meeting tomorrow

All students are requested to attend the meeting to be held tomorrow on time.
All students are required to attend the meeting to be held tomorrow on time.
这里用request或者required都可以了啦。你这个要是作业的话最好把"明天举行"这意思也对译出来，就是"to be held"呵呵。

All students are requested to show up on time for the meeting tomorrow.
挺客气的用 request,一般学校的告示大概比较常用 require 呐.

all the students are required to attend the request tomorrow on time.
