Explain the vocabulary to students. ☆教材解读☆ maybe? maybe为副词,意为“大概;或许;可能”。表示推测,一般位于句首。 Maybe these nutrients are helpful to your health.或许这些营养品对你的健康有帮助。　　 【辨析】　maybe,may be (1)maybe是副词,意为“也许,可能”,在句中作状语,相当于perhaps,常位于句首。 Maybe/Perhaps the weather will get better.可能天气会变得好一些。 (2)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”。 　　Maybe he’s wrong. =He may be wrong.或许他错了。 Maybe you are right and she may be a little late.或许你说的对,她可能有点晚了。 [设计意图]　通过学习聚焦语法内容和要点词汇,为后面的教学扫除生词和语法障碍。 StepⅡ.Lead in Leading in 【情景1】 Boys and girls!Look at the pictures.Please finish the conversations like this: T:What do you usually do on weekends? S1:I always exercise. T:How often do you play computer games?
