“Maybe” 和 “may be”，一个是副词，另一个是包含情态动词 “may” 和动词 “be” 的搭配。它们都有 “可能” 的意思，但两者的用法却不同。
 
Hi, everyone! What's the difference between maybe and may be? Well, we are going to find out in this English In A Minute.
May is used to express possibility – usually not a very certain one. It's a modal verb, so it's always followed by a bare infinitive. The bare infinitive of 'be' is… be! Using the two together, we can make a sentence:
Don't call her. She may be at work.
Now – maybe is just one word. It's an adverb and it has a few uses.
Most commonly it means 'perhaps' or 'possibly'. In this case it's often the first word in the sentence:
Don't call her. Maybe she's at work.
However, put it in front of an amount to mean 'around' or 'approximately':
