选D.maybe
由于句子中有are 这个系动词了,所以前面不能再出现系动词be,所以排除ABC,
maybe 是副词,表示也许.
翻译：工作了一天,也许你是又累又饿.

D maybe
Maybe you are tired and hungry after a day's work 这里 maybe 是副词

D.想必你是对AD有疑问？详解一下AD.
A的意思是“可能是”，例句：He may be in the classroom.他可能在教室里。
D意为“可能”。对比一下：Maybe he is in the classroom.
may本身也是“可能”之意，再加上be（是），就不难理解了。
不懂请追问！
