复习学案2: 人教版新课标高中《英语》必修3Unit 4 :Comprehensive Revision
Learners’ English level analysis学情分析：Certainly we need to identify factors which motivate and hinder students’ English learning. Significant differences exist in my classes. Only fifty percent of the students have the desire to be successful in learning English. A quarter of them are at a loss when dealing with basic junior English. A total of 40 students from my class are found to have some difficulty in learning and using English. Based on the findings, a number of recommendations were made. We have to stimulate interest in learning and using English. We have to consolidate basic knowledge. We have to urge the students to acquire English. We have to create learning atmosphere in many ways.Teaching content analysis教学内容分析：1. The aim of this class is to review this unit and further understand the topic of this unit--Astronomy: the science of the stars. According to the topic, the students should consolidate what they have learnt in this unit and develop the four skills--listening, speaking, reading and writing. There is no need to repeat the knowledge that they learnt. Students should be urged to get involved in using English. They should really master the knowledge and have the ability of learning.2. According to students’ concrete conditions, this period can be divided into the following parts:consolidation of the language knowledge, summary of the topic, output of the skills.3. Students should connect what they have learnt with reality, such as the launch of Shenzhou 7, so they can know more about the topic of this unit and have a sense of pride and care more for astronautics.theory, system, violent, in time, unlike, be harmful to, fundamental, exist, give birth to, prevent…from, puzzle, gentle, pull, cheer up, now that, break out, watch outThe noun-clauses, esp, the subject-clause(1).

Don't play with that thing.Step3 Grammar: Speak out the following sentences in the text, pay attention to the conj.设计说明：复习本单元语法项目（名词性从句），先让学生根据课本填写名词性从句的引导词，同时熟悉课文内容，然后跟读句子，意图是把语法的复习与口语训练相结合，如果学生能够非常顺畅地说出含有语法点的句子，那么肯定慢慢会领悟语法的内容的。本单元课文长难句也是含有语法项目的句子，所以兼有课文复习之目的。具体操作的难度在于从课文MP3中提取这些单个较难的句子录音。1. ________ it was to become was uncertain until between 4.5 and 3.8 billion years ago ________ the dust settled into a solid globe.2.The earth became ________ violent ________ it was not clear ________ the shape would last or not.3. ________ is even more important is ________ ________ the earth cooled down, water began to appear on its surface.4.________ was not immediately obvious ________water was to be fundamental to the development of life.5. ________ many scientists believe is ________ the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas.6.This produced a chain reaction, ________ made it possible for life to develop.7. ________ they suddenly disappeared still remains a mystery.8.They are putting too much carbon dioxide into the atmosphere, ________ prevents heat form escaping form the earth into space.9.So ________ life will continue on the earth for millions of years to come will depend on ________ this problem can be solved.1.What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe.2.The earth became so violent that it was not clear whether the shape would last or not.3.What is even more important is that as the earth cooled down, water began to appear on its surface.4.It was not immediately obvious that water was to be fundamental to the development of life.5.What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas.6.This produced a chain reaction, which made it possible for life to develop.7.Why they suddenly disappeared still remains a mystery.8.They are putting too much carbon dioxide into the atmosphere, which prevents heat form escaping form the earth into space.9.So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.设计说明：利用现成的swf动画进行语法讲解，该动画是提供情景讲解名词性从句的内容。教师结合讲解名词性从句的内容。练习的设计不仅仅局限于名词性从句，所以学生有可能思维定势而弄错从句的性质。1. ________ made the teacher proud was ________ 90% of the students in her class have been admitted to key universities.2. ________ fewer and fewer students showed interest in her lessons puzzled her.3. It was obvious ________ her hair was turning grey.4. ________ more countries can use natural energy in the future remains to be seen.5. He ran so fast ________ I could not catch up with him．6. Jane told me she won the match, ________ was a lie.1. What made the teacher proud was that 90% of the students in her class have been admitted to key universities.2. Why fewer and fewer students showed interest in her lessons puzzled her.3. It was obvious that her hair was turning grey.4. Whether more countries can use natural energy in the future remains to be seen.5. He ran so fast that I could not catch up with him．6. Jane told me she won the match, which was a lie.设计说明：阅读理解是高中英语教学的侧重点。其目的是不仅要让学生学会语言知识，获取文章提供的信息，领悟文章的内涵，更重要的是要使学生掌握阅读的方法和技能，成为独立阅读能力的人。从某种意义上说，阅读能力的提高，是听、说、写能力提高的关键。所以设计话题相关的拓展性阅读是很有必要的。教师在提示阅读技巧与方法的基础上，让学生自读、讨论，同时听录音强化，探讨问题答案等。这是能力提升的任务之一。丹尼斯·提托将进行太空之旅(字数322，参考时间：3分钟)Dennis Tito is a sixty-year-old American who lives in Los Angeles, California. He is in Russia now training for a most unusual trip into space. Dennis Tito paid the Russian government twenty-million dollars for the chance to travel in a Soyez spacecraft to the new International Space Station. His space flight will be launched on April thirtieth.Mister Tito says he has been interested in space travel since he was seventeen years old. That was when the former Soviet Union launched the first(1) satellite, (2)Sputnik. This interest led him to become a rocket scientist. He worked for the United States Jet Propulsion Laboratory in California. He left that job after a few years to start an (3)investment business. Today, Dennis Tito's company is among the nation's largest investment businesses. Reports say he is worth about two-hundred-million dollars. So he can easily pay twenty-million dollars for a trip into space.Mister Tito says he asked Russian space officials to take him because he knew they needed money to keep their space program alive. The first agreement was for him to visit the Mir space station. But Mir is old, and has experienced many problems. It will be taken out of (4)orbit next month, and will crash into the sea. Russian space officials decided to send Mister Tito to the International Space Station instead.This is not the first time the Russian space program has earned needed money by selling seats on its spacecraft. A Japanese television reporter flew on Mir for a price of twelve-million dollars. And the American space agency NASA paid four-hundred-million dollars to send several American astronauts to Mir.Mister Tito is now living and working at Russia's Star City training area to prepare for his ten-day trip. Why does he want to go into space? Mister Tito says he has been on Earth for sixty years and he now wants to take a look at the planet from space.(2) sputnik n.(前苏联)人造地球卫星(3) investment n.投资, 可获利的东西(4) orbit n.轨道 v.绕...轨道而行，沿…轨道飞行1.What’s the topic of the above passage?________________________________2.Who did Dennis Tito work for before starting an investment business?________________________________3.Why did Russian space officials decide NOT to send Dennis Tito to the Mir space station?________________________________4.

Are you interested in space travel?

The whole nation cheered up immediately watching the scene. It was obvious that walking did need a bit of practice now that gravity had changed. The long and violent pull of gravity might cause an accident. In addition, all the major systems had been fully prepared to prevent anything harmful from happening. Once an American spacecraft crashed in the sky.Space walk would be fundamental to the country's future plans to build a space station. Thus, the space walk would be one key step of the space program. We have, in our turn, become a country to send man into space. Unlike cultural relics, it was a signal of China's growing global influence. Step7 Homework: Do the Unit Test Ex.设计说明：作业的设计是进一步巩固单元知识并强化能力训练，所以适当的练习题还是必需的，分为必做与选做两部分。这个test可以是学生自评，也可以是教师评价。English should be acquired, so the students have to be involved in the tasks. But some students are not active, even worse, a few students keep silent. We should offer more opportunities to them, which can not only open their mind but also improve their comprehensive ability of learning English.
