His . is .并教学glasses 和shoes的发音。教发音时，以旧引新，培养学生的拼读能力。)2.T: This is our friend Tim. Here come our friends Mike and John. They are talking. What are they talking about ?

This time , lets listen and repeat.（设计意图：听音正音并模仿。模仿是学习语言的最好途径。）2. Ss read by themselves.3. Ss read in roles. 4. T: Good voice. We have learnt some sentences which can be described looking .Let s find and underline the sentences from the talk.（设计意图：回顾文本，明确本课所学，为下面的实际运用语言做好准备。）Guessing gameT: Please use the sentences to play a guessing game. Here are some pictures of super stars .Who are they? (向学生展示图片并分发给个小组)Lets guess like this :A: I have a good friend . He is tall and strong.He has long arms .

(PPT 呈现图片并放录音)（设计意图：教师以急促紧张的语调打断学生的展示，插播寻人启事，让学生通过听寻人启事，辨别选择图片，来进行听力上的输出运用。）2. Look and sayMy friends sons name is Wu Yifan , too. He cant be found still. Lets help. Now please look at Wu Yifan carefully., then describe him more carefully to others. (PPT 呈现图片和可能用到的词汇句型结构。)（设计意图：接着上一环节，对选中的图片向他人描述，帮助寻找丢失的孩子。在助人为乐中输出本课所学。）3. Make more friends（PPT呈现吴一凡及声音）Wu Yifan : Im coming. Thank you for helping me. Now were friends. Please describe your friends to me or others. Lets make more friends. （设计意图：遵循从教材文本走向学生生活的课标精神，通过吴一凡的交更多好朋友的提议，学生互相向同伴描述自己的好友，从而交到更多的好朋友。在这一活动中，学生综合运用了 姓名，性别，身材，五官长相及品德等的描述，在运用中，内化了所学。）Sum : T: Today we have learnt 。( 让学生说)。And we have learnt how to describe looking.情感渗透;T: (接上句) But we know : Someone is very short, someone is very fat , Someone is unhealthy, someone has glasses . We shouldnt laugh at them, because we are friends.（设计意图：无论高矮胖瘦，甚至残疾，都不要嘲笑，因为我们是朋友，回应本课主题。）板书设计： Unit3 B Lets talkHe is tall and thin. He /She has .His/ Her is/are .教后反思：1.教学活动贯彻一条主线。本课切合本单元的的话题，以朋友为主线，穿起了各个教学活动。（从free talk的 Lets be friends together ；复习A部分交的朋友Tim ，引出老朋友Mike and John；进入文本，通过问题链，学习到如何描述朋友；通过寻人启事，帮助找到老师朋友的儿子，老师的儿子提议互相交更多的朋友，综合运用了所学；在情感中深化朋友的主题。）2. 遵循从教材文本走向学生生活的课标精神在文本中，提取信息提取语言训练语言；在生活中运用语言。3.活动设计符合学生的年龄特点和心理特点。如采用大耳图图和找不同来训练本课的核心语言，是学生愿意并且喜欢的，因此效果就很好。4. 学以致用对本课的新内容Yes, you are right 和 or 作为评价语和指导性语言贯穿课堂始终。给学生起了很好地示范作用，进一步加深了学生对Yes, you are right 和 or的语境理解及用法。如：Yes, you are right用于学生回答正确是即用。Check时运用Right or wrong, yes or no 也对or的理解和用法起到了类似的作用。本节课还有一些有待改进的地方，如在进行操练时，要关注学生的语音语调，刚开始，用手势表示升降，给学生的语音语调以形象直观的引导，也更便于学生理解一般疑问句的语调。本课是新版PEP四上Unit3 B的一节对话课。本课的教学活动设计1.遵循英语学习规律：理解-巩固-运用，先输入，后输出，做到听说领先。2. 活动设计符合学生的年龄特点和心理特点。如采用大耳图图和找不同来训练本课的核心语言，是学生愿意并且喜欢的。3.整体呈现，做到呈现、训练时，有语境支持，坚持意义先行。由旧引新，突出重点语言训练。4.教学活动贯彻一条主线，体现单元主题。
