Everyone,enjoy ____________?请问这里填yourself还是yourselves,是强调整体还是个体还有最后一个不是问号应该是！我打错了

Everyone,enjoy yourself?
我觉得everyone是指个体,跟everybody同意.
还有楼上的,enjoy后面动词跟ing形式,是listening to music

应该是yourself,没有yourselves吧？

Everyone,enjoy yourselves!
再看这道反意疑问句:
Everyone is here,aren't they?
英语中everyone如果用代词来代替的话,应该当作复数概念.

listen music (Chinese meaning is 听音乐)

括号内为解释,答案即是括号前的两个单词~
