1、心情不好时:
Leave me along,please!(请走开!/请离我远点!)
2、怕传染别人疾病(打个比方哈):
Please keep distance as far as possible!
Please keep away from me!
3、失恋了,请前恋人走开(比方,too)
Go away, please!
Leave me along as far as you can! Please!(情绪激动)
如果按字面译呢就please keep away from me就可以了,不过用leave me alone就显得觉得那人烦所以要他远离
Please leave me alone.
Please keep away from me.
应该是please keep away from me,
stay away是外出的意思
