英语人教版七年级上册How much are they？.doc

How much are they？教学设计主题阐述：在英语教学中，创设生动形象的情境，既能活跃课堂气氛，激发同学的学习兴趣，锻炼同学的语言能力，又能培养同学的思维能力和想象能力。英语课堂情境的创设方法多种多样，但如果单纯为了创设而创设，脱离了学生的实际，变成一种形式，就会使得所创设的情境变得枯燥，牵强，学生的积极性也得不到调动，所以情境的创设离不开“真实有效”这个原则。从这一原则出发我确立本课的研究主题为：创设真实情境，提高课堂效率。教学目标：知识目标：1、能够听、说、读、写便宜的和昂贵的英语表达方式：cheap, expensive。2、能够听懂并且说出有关商品价格的交际用语：How much is it / this ? Its yuan .How much are they ? They are yuan .Thats too expensive . That one is yuan .Its cheap .能力目标：能在相应的情境中正确运用所学的有关商品价格的交际用语。情感目标：1、通过积极语用所学英语知识进行表达和交流，逐步培养学生良好的语言表达能力。2、在活动中进一步培养和锻炼学生自己解决现实问题的能力。教学重点：1、词汇：expensive cheap2、句型:How much is it / this ? Its yuan .How much are they ? They are yuan .Thats too expensive . That one is yuan .Its cheap .教学难点：1、单数和复数商品表达和询问价格的不同方法:How much is it / this ? Its yuan .How much are they ? They are yuan .2、单词expensive的发音教学准备：多媒体 单词卡片 实物教学过程：一、歌曲热身激发兴趣T：Hello！Boys and girls !Ss: Hello ! Miss Yang !T: Nice to meet you !Ss: Nice to meet you too !T:At first lets sing the song , OK ?Ss:OK!Ten little Indian Boys【设计意图：良好的开始是成功的一半。课前歌曲热身能够把学生的思维迅速带回到课堂中来。选择这首歌曲做热身是因为在本课的教学中要学习钱的表达方式，所以利用这支歌曲既能激活课堂又能复习数字，为本节课后面的学习做好准备。】二、复习旧知做好铺垫：T：Lets play a game . Guess the worlds .(猜单词游戏)【设计意图：兴趣是最好的老师。利用猜单词这个游戏把枯燥机械的复习单词变得生动有趣，激发学生的学习兴趣。】三、创设情境导入新课：T：This is my pen . And its broken .I think its the oldest one in our class . So I want to buy a new pen .Today I will go shopping . Where should I go ?Ss：文具店T：Do you want go shopping with me ?Ss: Yes !T : OK ! Today we will learn Unit 5 Shopping .(板书课题，师领读课题)【设计意图：创设生动形象的情境，能够激发学生的学习兴趣。因为本节课主要是学习购物时询问价格的交际用语，从教学内容出发，我创设了去文具店买文具的情境，使得情境有真实感，有利于本节课的教学。】四、置身情境学习新知(一)听录音T：Here is the stationery shop .Lets have a look .【设计意图：通过听录音帮助学生整体感知本课的学习内容。】(二)How much is it/ this ? Its yuan .1、T : Look at this pen . How much is it ?Ss : Its 20 yuan .T : How much is it ? Whats meaning ?Ss：这个多少钱？T : Yes .(板书句子)（领读句子）T : You also can ask : How much is this ?T : Here is a pen you can ask : How much is this pen ?2、替换练习：How much is this ?3、Work in pairs .（同桌之间练习对话）How much is this ? Its yuan .（三）How much are they ? They are yuan .1、T: They are scissors . How much are the scissors ?S1: They are 15 yuan .（练习句子）How much are the scissors ?They are 15 yuan .2、T : I like this pen . I also like that one . I want to buy them .How much are they ?They are yuan .T :（板书句子）How much are they ?对复数提问时时我们可以用How much are they ?T：You can answer : They are yuan .3、替换练习（大屏出示图片）How much are they ?

Thats too expensive !T: Guess , expensive whats meaning ?（板书，讲解，练习，拼读单词expensive）2、T: Thats expensive .T：Thats too expensive !（对比两样物品的价格）T:（出示各种图片）Its yuan .

Its cheap .Cheap whats meaning ?Ss:便宜的。（板书，讲解， 练习 ， 拼读单词cheap）2、练习句子That one is yuan . Its cheap .【设计意图：创设生动形象的情境，既能活跃课堂气氛，激发同学的学习兴趣，锻炼同学的语言能力，又能培养同学的思维能力和想象能力。在整个新知的学习过程中我以文具店购物为主线，使学生置身于情境中，真实有效的语言环境帮助学生更好的学习本课知识，提高了课堂效率。】五、模仿情境巩固新知1、猜价格：2、Listen and speak .3、看图说话。【设计意图：多样有效的教学活动才能使学生保持长久的学习兴趣。在巩固练习部分我延续了文具店里购物的情境，设计了三个环节，既有必要的机械模仿和看图说话又有有趣的猜价格游戏，使课堂生动，高效。】六、合作学习运用新知T：If your group has 50 yuan . What can you buy in the stationery shop ?Things to buyPrice【设计意图：英语课程标准指出：要使学生形成初步用英语进行简单日常交流的能力，为进一步学习打下基础。这个环节遵循了这一要求，学生
