Module3 Unit2第二课时教学设计 外研版英语八年级下册.docx

基于课程标准的“教学评一体化”设计课时备课课题八下 Module 3 Journey to space Unit2日期课时2课型读写授课教师目标确立依据课标分析课标摘录义务教育英语课程标准语言技能四级标准：读：1. 能读懂简单的个人信件、说明文等应用文体材料；写：2. 能在教师的帮助下或以小组讨论的方式起草和修改作文；语言知识四级标准：语法：1.理解现在完成时并能在特定语境中使用； 3.在实际运用中体会和感悟语言形式的表意功能。课标分解1. 能通过阅读，简单介绍文本相关内容；2. 能通过具体语境和练习，正确使用现在完成时；3. 能通过小组讨论，简单介绍太空poster。教材分析 本模块以“太空旅行”为话题，通过描述人类探索太空的历程强化对科普说明文的理解能力。Unit 2的主要内容是介绍太空的基本知识和人类对探索太空付出的努力。学生以理解为主，最后一组问题设计地很巧妙，也正是学生想问的，也能够引起学生的积极思考。在本课中，利用现在完成时去表达人类探索太空已经发现的事物，属于新知和重点。这就需要教师创造情境，以活动为载体，将词汇和句型结合。学情分析学生们在第一课时中已经对一些太空知识有了基本了解，但是对一些新的语言点的使用比较陌生，现在完成时中对于already/ just/ yet的练习比较少。在第二课时中将通过阅读扩大学生知识面，通过知识点的讲解和练习增强语用功能。教学目标通过本课时教学，让学生能够：1.在语境中记忆并强化用本单元有关的词汇none, environment，solar, systemgroup, galaxy，universe, light，impossible, out，communicate；2.通过读中学，熟练掌握目标词汇和语法知识，并能灵活运用；3.通过比较一般现在时和现在完成时，熟练掌握现在完成时，并能复述文本主要内容；4.通过拓展训练，熟练阅读技能，拓展文本资料；5.通过介绍poster，感受太空探索取得的进步，树立不畏艰难、积极向上的信念。 评价任务 评价标准1. 在读中完成P2-3复述（指向目标3）准确复述星体之间的关系2. 学后完成用单词的适当形式填空。（指向目标1）能用单词的正确形式填空3. 读后完成知识点学习及训练（指向目标2准确写出答案4.拓展阅读补充相关知识（指向目标4）能在规定时间内找到准确答案5.根据poster内容简单介绍自己知道的太空知识（指向目标4）较为准确、流畅地说出 教学过程教学环节 教学活动 评价要点Step 1Warming up1.

Astronauts go on spacewalks for many reasons. For example, experiments can be placed on the outside of a spacecraft. This lets scientists learn how being in space affects(影响) different things. By going on spacewalks, astronauts can also fix things instead of bringing them back to the earth to fix.    When astronauts go on spacewalks, they wear spacesuits to keep themselves safe. Inside spacesuits, astronauts have the oxygen(氧气) they need to breathe and the water they need to drink. To keep the astronauts and the spacecraft safe, the astronauts must leave and go back to the spacecraft through a special door. When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft. Tethers are like ropes, connect the spacewalkers with the spacecraft. They keep astronauts from floating(漂浮) away into space. Another way astronauts stay safe during spacewalks is by wearing a SAFER. SAFER is worn like a backpack. It helps an astronaut move around in space.    How do astronauts train for spacewalks? One way is by going for a swim. Floating in space is a lot like floating in water. Astronauts practice spacewalks underwater in a huge special swimming pool. For every one hour they will spend on a spacewalk, astronauts need to train seven hours in the pool. Another way astronauts practice for a spacewalk is by using virtual reality(虚拟现实). It looks and feels just like a spacewalk.Today, only three countries have finished spacewalks independently. They are Russia, the United States and China. The first person to go on a spacewalk in the world was Alexei Leonov from Russia. Zhai Zhigang is the first Chinese astronaut to go on a spacewalk. The world record of spacewalks is held by Russian astronaut Anatoly Solovyev. He has been on 16 spacewalks and spent more than 82 hours outside in space.(1) About the spacewalk, we can know_    .A. some things can be fixed by astronauts during spacewalksB. all experiments must be placed on the outside of a spacecraftC. an astronaut can get out of a spacecraft any time while in spaceD.a spacewalk lets scientists learn how being in space affects different things(2) How many ways to keep the astronauts safe during spacewalks?A.Two.
