九年级英语Shopping教案
每个老师上课需要准备的东西是教案课件,大家在仔细规划教案课件。必须要写好了教案课件计划,才能促进我们的工作进一步发展!那么到底适合教案课件的范文有哪些?为了让您在使用时更加简单方便,下面是小编整理的“九年级英语Shopping教案”,仅供参考,大家一起来看看吧。
九年级英语Shopping教案
教学内容:Shopping经点答疑
1.学好本单元知识的关键是什么?
认真复习以前学过的现在完成时,通过旧知识引出新知识,注意二者的联系和区别:
过去完成时的基本用法与现在完成时基本相似,所不同的是:现在完成时的动作在现在以前完成,过去完成时的动作在过去某一时间以前完成,那么,使用过去完成时就非先有这样一个过去某一时间不可。例如:
Ihaddonemyhomeworkbeforelunch..我在午饭前把作业做完了。
句中的lunch即是过去某一时间,而过去完成时haddone这一动作就是在lunch之前完成的。如果只说Ihaddonemyhomework.听者就会觉得难以理解。由此可见,过去完成时可以说是一个相对的时态,它不能离开过去时间而独立存在。再如:
BytheendofthatyearWendyhadcollectedmorethanathousandforeignstamps.
到那年年底,温迪已收集了一千多张外国邮票。
但过去某一时间也可以暗含在上下文中而不表示出来。例如:
Theroadswerefullofpeople.Wehadntforeseenthat.
路上都是人,这是我们事先未料到的。
2.学习本单元知识的目标是什么?
(1)掌握过去完成时的用法。
(2)懂得现代购物手段。
(3)掌握目的状语从句。
1.怎样理解so...that和sothat结构?
(1)so...that结构中,that引导结果状语从句。例如:
Shewassotiredthatshefell.她累得倒下了。(她是如此的疲劳以致于倒下了)
(2)sothat既可引导目的状语从句,也可引导结果状语从句。例如:
Istoppedsothatyoucouldcatchup.我停下来以便你能赶上。(目的)
Nothingmorewasheardofhim,sothatpeoplethoughthewasdead.
未再听到他的消息,因此人们以为他死了。(结果)
2.“Wouldyoulikemetolookintheback?”一句中would是什么用法?
是wouldlikesb.todo结构,意为“想要某人做某事”。例如:
Iwouldlikeyoutohelpme.我想要你帮助我。
另外,could和would都可用来表示非常礼貌的委婉的请求。例如:
Couldyouanswermyquestion?你能回答我的问题吗?
Wouldyoupleasedomeafavor?请帮个忙,好吗?
注can和will也可用于上述句子,但语气没有could和would那么委婉,因此,疑问句中常用could代替can,would代替will,以表示礼貌的请求。
3.在Thiscameraseemedtoofferthemostatthebestprice.句中,price的用法及其他常用短语是什么?
(1)n.价格,代价,价值。例如:

二、课后反思:
通过对本节课的学习,培养学生通过课前预测(predicting),略读(skimming),找读(scanning),了解重点大意(majorideas)等阅读微技能来逐步提高阅读水平。学生理解了课文的内容,并能用英语将课文的内容通过表演的方式呈现出来。并且懂得了当别人遇到困难时,学会即保护自己,又要帮助别人。
本节课的设计简易明了,并且能够层层深入,通过运用不同的教学方式来设置活动,达到学生对课文的理解。运用了角色扮演的方式,来激发学生对故事的重现,扩展了学生的思维。增强了课堂教学的趣味性和实用性。
Video部分的失误成了这节课最不应该出现的问题。
三、课例点评:
1.赵老师在课堂上教态亲切、自然、有激情。口语流利,能用全英语驾驭教学。
2.这节课采用多媒体教学,课件精细,设计构思精巧,准备充分。

4.整节课自始至终激发学生积极参与、体验、合作与交流,充分发挥了学生的主体作用。
建议:1.课堂上问题的设置应该考虑到学生的各个层面,有难有易,有梯度。
2.课后要布置预习作业。
