您好.
你这句话是有毛病的.
首先,everyone 一般被看做是一个单数的名词,表示每一个人,个体.所以 enjoy 要用 enjoys.
不过,后面您用了 themselves ,我认为是正确的.
虽然everyone 表示每一个人,而且动词要用单三形式,可是在英语中并没有表示“她和他”并用的单数“反身代词”,所以要用复数的.
而且 everyone 虽然表示每一个人,可是却通常是表示“一个整体”.
所以要用 themselves.
还有以下的例子,请您看看：
Even better, everyone enjoys their work more - including you.
更好的是所有人及你都会更喜欢自己的工作.
Do you think everyone enjoys their weekends? Old Henry does not.
你认为每个人都喜欢自己的周末吗?老亨利就不喜欢.
Almost everyone enjoys the society of friends and family members.
几乎每一个人都喜欢朋友、家人之间的友谊.
