"这是你在这次工作中必须注意的几点事项."用英语怎么翻译?

These are the things you must pay attention to this time。

口语中：
This is what you need to notice(in your work 可以不说).

These are the cautions which should be observed in the work.

These are items you should focuse on in this job.

These are events should be concentrated on during your work.

These are cautions you shold keep in mind during work.（推荐）

如果不是官方文书，普通的口头关照对此要求不用太苛刻，基本上来说状语从句爱怎么所都不要紧。主语从句里头最重要的就是那个名词，根据具体需要说明的东西以上三句里头的都可以用。
item主要用于客观事物
event主要用于客观事务
caution则是“注意”“注重点”的意思，比较具有普及型，可以说什么地方都可以用，因此个人推荐这个
