人教新目标英语八年级上册Unit 2 How often do you exercise?词句精讲精练撰稿：审稿：词汇精讲1. maybemaybe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。

例如：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。

【拓展】（1）maybe和may be的辨析：maybe是副词，而在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”。

例如：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。

（2）maybe和may be可相互转换。

例如：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。

2. althoughalthough的意思相当于though，意为“尽管，虽然”，用来引导让步状语从句。

它所引导的从句不能与并列连词but; and; so等连用，但可以和yet; still等词连用。

例如：Although he lives alone, he doesn’t feel lonely.= He lives alone, but he doesn’t feel lonely.虽然他一个人住，但他并不感到孤独。

There is air all around us, although we cannot see it.虽然我们看不见空气，但空气却存在于我们的周围。
