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.
don`t think fifteen-year-olds should be allowed to扎耳朵眼).
被允许)choose her own clothes.
talk取代做作业).
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.
not be be not should be
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。
should allow children to choose their own hobbies.(改为被动语态)
childrenchoose their own hobbies.
g**e tom a flower last night .(改为被动语态)
