To improve the students ability of reading and to make them fully understand the passage and know the importance of carefulness2. To improve the students ability of communicationTeaching aids: Computer, blackboardTeaching procedures:I. Revision1. To ask some students to act out the dialogues in L972. To practise Fill in the blanks with: send out, get through, ring back, make up or out of breath:1) Please _ to me as soon as you get the latest news.2) The ship was in danger and the captain _ a message for help.3) I tried again but I couldnt _ to New York because the line was so busy.4) After all the running, the runners were all _ .5) Jim _ an excuse for being late again.II. Lead in CAI shows a movie of the following story - “ In July, 1999, a country girl student took part in the entrance examination and was accepted by a college in Beijing. But the postman made such a careless mistake that the admission notice was sent to a wrong place and left there for half a year. When the letter was finally found, it was too late. The girl lost her chance to go to college that year.” Questions: What do you think of the story? Is it a sad story? Why? .T: Today we are going to learn another story about carelessness. Luckily it has a happy ending. ( To appear the title: At the conference )III. Reading 1. Skimming Question: What happened to Dr Baker at the conference? ( Answers: The organizer mistook him as Dr Peter Baker, an expert on DNA. The organizer had thought he was The organizer believed Dr Baker invited was ) 2.

Group workDiscussion What can we learn from the story?( First, we must be careful in everything so as to do things well. Second, we must make good use of time and learn as much as we can in order to be useful to our country.)IV. Homework1. Finish off Wb.& Ex.b. exercises.2. Write a summary of the story about Dr Baker. 3. Retell the story in your own words.鉴于这两篇课文的内容是相连的,因此采用整体教学( 同样共用二个课时)。 在这第一课时里,主要进行1.阅读指导, 重在对语篇的理解; 2. 应用任务型的教学方法为学生创造真实的语境, 通过其相互间的帮助、合作，共同完成任务，在潜移默化中提高英语的交际能力；3. 以现代教育技术手段-多媒体进行教学，体现直观、生动的教学效果。主要教学环节有：1. Lead in（导入） 选用一则“邮误”的短片故事让学生充分意识到粗心大意的危害性。2. Skimming（略读） 其目的是通过扫描迅速掌握主旨大意（to get the general idea of what it is about）。为达到这一目标,老师在发出First reading（第一遍阅读）指令时同时打出问题：What happened to Dr Baker at the conference?3. Scanning (跳读/寻读) 其目的是搜索、确定信息，从而找出答案、解决问题 （to be able to scan the text for particular bits of information they are searching for），通过所设计的填空题完成Task（任务）。（学生每口头答对一个，画面上即飞入一个正确答案）4. Careful reading（仔细阅读） 要求就语篇内容动手写几个statements（情形），这statements 可真可假(True or False)。5. Pair work (同伴活动) 请同桌或其他同学 “judge the statements” （进行正误判断）6. Guessing the meaning of the new words（猜词）（用自定义动画）7. Dealing with the language points（语言点处理） 根据学生的具体情况与实际需要进行尽可能简要的讲解，让其初步掌握该课语言知识。8. 同步显示课文画面与录音，为能更流畅和完整的口笔头表达作准备。9Group work(小组讨论)Discussion: What can we learn from the story? (我们从这篇故事中学到了什么？) 以此话题激活他们的思维、激发他们的情感，让他们谈感想，明白在平时的学习中只有认真细致、勤于钻研，才能拥有渊博的知识、成为社会有用的人才。 (.First, we must be careful in everything so as to do things well. Second,
