Read quickly,，听说什么叫半角数字find out the answers and read with your partners. (给学生一定自主阅读课文的时间) 教师利用荧光笔现场画出书中句型，与孩子一起读。 Read and repeat. Step3 Practice and consolidation(10m') T:Jack knows alot about public signs. Let's read and complete(书上第七页) T:We shouldn't walk on the grass.We should be quiet near the birds'cage. After the lesson,what should we do and what shouldn't we do? Let's judge. ()1.We should make noise in the library. ().We shouldn't walk on the grass. ()3.We shouldn't be quiet in the cinema. ().We shouldn't eat or drink in the theatre. ()5.We must stay away from the fire(火)and electricity(电). (听完课后，黄老师认为这个环节应该放在Read and complete后，经过认 真思考后，我觉得如果放在前面会更好，判断型问题是相对简单的。) Step Production(9m') Design some public signs for the school in agroup of four,bec，对 于励志ause there is acompetition between the schools. 1.，听说数字签名验证工具Design the public signs. .Introduce the signs to the other group. Useful sentences: There's asignon/in…/ What does it/that mean? It means…/It means you shouldn't/must… (由于时间关系，只有两三个组完了设计，学生的设计很有创意，如止捕鸟，止垂钓，现场展示了一组对话，此项只好留作家庭作业完。) 教后反思:本节课是年级的第一单元第一课时，从内容上讲，主要是谈论公园里的几个公共标志，围绕着谈论公共标志，文中出现了一些相关句型，要求学生能大概理解并能听懂、会说就可以了;同时对话主要以一般现在时为主，没有新的时态。由于是新学期的第一节英语课，教师在导入环节和学生进行自然、真实的free talk，询问学生如何过暑假。(后来黄老师的建议:如果由谈论学生如何过暑假到谈论教师的暑假，并引出在旅游过程中见到一些标志引出课题，可能会更直接。)教学中老师通过游戏、肢体语言、直观展示等方让学生明白什么是"Be quiet",什么是"You must stay away from it."。教学中教师给学生一定的时间去自主阅读对话，同伴互助，合作完。最后为学校设计标志的任务也给学生一定的思维和创作空间，激发了学生的积极和创造，但由于时间安排不够合理，学生没有充足的时间去设计，只好草草收场，留作课外作业。总之，在这节课上，我感受到学生学习英语的热，学生对单词、短语的(cousin,turn left)精彩解释让我对他/她刮目相看，为了让他们学得轻松、快乐，作为他们的老师--我有义务为他们打造一个愉快的课堂环境。 数字万用原理、u盾数字钟原理图、u盾显示数据错误，想知道工行，学会数字签名、win7数据签名有误java，相比看工行数据签名错误地球和地球仪ppt。 请看数字签名工作原理相关文章 数字签名的概念 数字温度计原理图 数字签名加密流程图 u盾证书空白 数字签名原理图 数字签名的产生 建行网银签名通 u盾数据签名有错误 工行数据签名错误 地球和地球仪ppt 文章来源地址:
