4. Maybe she looks after her mother every day.(改为同义句) She --

Maybe she looks after her mother every day.
She __ __after her mother every day.
这道题其实要替换句中的maybe ,这里是副词作状语,意思是也许.
第二空又缺少谓语 ,要表示也许要照看 那就可以用情态动词may + V 来表示,意思是或许会做某事
She may look after her mother every day .
又如,Maybe he is a teacher.（maybe 副词作状语）
He may be a teacher .(may be 作谓语,所以应该 分开写)
