大家好，今天在杂志中的boredom例句看到一个句子如下
For Jane, every day is just work, eat and sleep. Life is full of

觉得有点困惑的是 is just work, eat, and sleep.

抑或是用Ving 的写法
working, eating, and sleeping.
如果要用名词，觉得应该要用eats
work, eats, and sleep.
所以想问杂志中的写法是否正确呢?

把它想成她每天做的事是这些，everyday前省略了all shedoes这样，

(All she does) every day is (to) 原型V
