教学设计被动语态一般现在时 一般现在时的被动语态 课型：前置语法课 教学目标： 1.体验生活，由某人干某事感知主动语态；某事被某人做感知被动语态 2.通过例句初步把握被动语态的结构 3.能把一般现在时的主动语态变被动语 教学步骤： Step1、感知主被动语态 1.Children love this song. 2.Tom cleans his bedroom every day. 3.Thanksgiving is celebrated on the fourth Thursday in November by people. 4.He is still remembered by people today. 5. Computers are used by us every day. 注：英语中有两种语态：主动语态和被动语态。英语的语态是通过动词形式的变化表现出来的。 主动语态表示主语是动作的执行者。 例如：Many people speak Chinese. 谓语：speak的动作是由主语many people来执行的。 被动语态表示主语是动作的承受者，即行为动作的对象。 例如：Chinese is spoken by many people.主语English是动词speak的承受者。 (设计意图：通过对比感知，学生能明确理解被动语态) Step2、总结被动语态结构 1,被动语态的构成：be + 动词的过去分词； 2,人称、数和时态的变化是通过be的变化表现出来的； 3,一般现在时被动语态的构成： am / is / are +动词的过去分词+(by+动作执行者) 例如： Children love this song. (主动语态） This song is loved by children.(被动语态） Step3.小测试 ：(注意结构am / is / are +动词的过去分词) 1、English _ (speak) by many people. 2、Tea _ (grow) in Southeast China. 3、Many trees _ (plant) in North China. 4、The brush _ (make) of bamboo and animals hair. 5、Confucius _ (know) as a great thinker in China. 主动变被动 1.
