maybe和may be的区别He may be in the office.= Maybe he is in the

maybe是副词,意思是“也许、可能”,在句中作状语,相当于perhaps,常位于句首.
Maybe she’ll come this afternoon.她可能今天下午来.
Maybe you put the letter in your pockets.大概你把信放在衣袋里了.
在may be中,may是情态动词,be是动词原形,两者构成完整的谓语形式,与主语形成系表结构,意为“也许是、可能是”.
He may be a soldier.他可能是军人.
You may be right.
= Maybe you are right.你或许是对的.

maybe是一个词，表示可能。may be是两个词，其中may表示可能，be是be动词

既然它已经是副词了，当然可以修饰is
副词笨来就是修饰形容词和动词的呀
