He ___________ know where her house is.
A.maybe B.may be C.may D.must be
这题为什么选C ,而不选B

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.没有may be +动词的用法.
首先你要弄清楚may be 和maybe的意思
may be和maybe一分一合,但它们的含义和用法却截然不同.
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,主语形成系表结构,意为“也许是、可能是”.
I can’t find my watch.It may be in your pocket.
我找不到我的手表了,它可能在你的口袋里.
He may be a soldier.他可能是军人.
maybe和may be可相互转换.
He may be in the office.
= Maybe he is in the office.他或许在办公室.
You may be right.
= Maybe you are right.你或许是对的.
