Unit 3 Teenagers should be allowed to choose their own clothes. 课型：新授 主备人：孙荣杰 审核：九年级英语备课组 课时：6课时 Section A （2课时） [学习目标] 1.情感态度与价值：（1）培养学生人际交往的能力。 （2）让学生学会感恩。 2.知识与技能：（1）学会含有情态动词的被动语态。 （2）学会谈论允许做的事。 （3）表明观点赞成与反对。 3.教学重点： 含有情态动词的被动语态的构成和用法。 重点掌握下列句型： （1.）I think students should be allowed to do homework with friends. （2.）Sixteen-year-olds should not be allowed to drive. 4.教学难点：主动与态与被动语态的转换。 [课前准备] 1.认真预习课本18页1a，1c并试着完成下列练习。 根据汉语完成句子。 1.-----------------------------------------------(十六岁的孩子)should be allowed to drive. 2.I don`t think fifteen-year-olds should be allowed to---------------------------- (扎耳朵眼). 3.Ann------------------------------------------(被允许)choose her own clothes. 4.They talk-------------------------------------------------------------(取代做作业). 5.They should stop wearing that ----------------------------------------------(傻气的耳环). [课堂学习] 1.预习情况与你的同学进行交流。 2.教师点拨：英语动词除了有时态外,还有语态,表示主语和谓语的不同关系.如果主语是动作的执行者,谓语动词用主动语态;如果主语是动作的对象,谓语动词用被动语态.动作的执行者有by引入的短语表示,但往往被省略;动作的对象则充当了被动语态句的主语.汉语中常用挨.被.受等词来表示这个意思. 3.听力，口语能力训练。听磁带同学们一起完成 1b，2a,2b.然后大家一起讨论所听到的结果，共同完成此项练习。 [规律总结：方法点拨] 例题：Teeagers---------allowed to diver in the street. A.should not be B.should be not C.not should be D.shouldn`t 解析：本题考察的是含有情态动词的被动语态结构，其结构为“情态动词+ be +动词的过去分词”。should be allowed意为“应该被允许......”，其否定式应在情态动词后加not，即shouldn`t be allowed,，故选A. 方法点拨：Ann is allowed to choose her own clothes. beallowed todo sth. 构成被动语态 ，意思是“被允许做”主语是动作的承受者，allowed 后必须跟不定式形式，例如： She is allowed to watch to watch TV for an hour every day. [巩固练习]句型转换 1.Parents should allow children to choose their own hobbies.(改为被动语态) Children ---------- ---------- ---------- -----------choose their own hobbies. 2.Lily gave Tom a flower last night .(改为被动语态) Tom--------- ----------a flower last night-------- Lily. 3.Lucy goes to school by bike. Lily ghoes to school by bike, too.(改为同义句) Lucy goes to school by bike,and -------------- -
