高一英语必修3Unit 4Astronomy the science of the stars知识点总结
Unit 4 Astronomy：the science of the starsPeriod 1 Grammar points.一．语法要点主语从句：在复合句中作主句的主语的从句叫主语从句。
引导主语从句的词有连词that, whether；连接代词who, what, which；连接副词when, where, how, why等。
Eg: Which team will win the match is still unknown.主语从句放在句首，句子常显得笨重，因此一般把它放到句子后面，前面用引导词”it”来作主语。
Eg: It’s strange that he didn’t come yesterday.二．重点难点1．Nobody knew that it was going to be different from other planets going to be different from other planets going round the sun.going round the sun 为现在分词短语定语，表示一般的动作。
Eg: Men breaking the law will be punished.现在分词短语，也可表示进行的动作2. Weather life will continue on the earth for millions of years to come will depend on whether this problem can be solved.for millions of years to come 中不定式to come 作定语，与前面的名词有逻辑上的主谓关系。
Eg: She is the last person to tell lies.3．The problem was that the earth became violent because it was not clear whether the solid shape was to last or not.The problem was that …, that 引导表语从句，that 只起连接作用，无意义，但不能省略。

Unit 4 Astronomy：the science of the stars 【美文阅读】关于大地起源的神话有许多许多，你了解多少呢？The sky and the earth were at first one blurred entity(混沌整体) like an egg. Then Pangu was born into it. The separation of the sky and the earth took eighteen thousand years. The yang which was light and pure rose to become the sky，and the yin which was heavy and murky(黑暗的)sank to form the earth. Between them was Pangu, who went through nine changes every day, his wisdom greater than that of the sky and his ability greater than that of the earth. Every day the sky rose ten feet higher, the earth became ten feet thicker, and Pangu grew ten feet taller. Another eighteen thousand years passed, and there was an extremely high sky, an extremely thick earth, and an extremelytall Pangu. After Pangu died, his head turned into the Five Sacred Mountains(Mount Tai, Mount Heng, Mount Hua, Mount Heng, Mount Song), his eyes turned into the moon and the sun, his blood changed into water in river and sea, his hair into grass. In all, the universe and Pangu combine in one.【诱思导学】1．Do you agree on the forming of the universe？Give your reasons.________________________________________________________________________________________________________________________________________________2．What kind of people is Pangu in your eyes?________________________________________________________________________________________________________________________________________________【答案】 1.No，I don't agree.Because the scientists have already found out how the universe formed.2．I think Pangu is very great and determined.He is a hero.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，就下一堂课对课文的全面理解起到一个铺垫作用。

Project.They represented the usual range：two were close to dropping out before they started the project，while others were honors students.Their guidance teacher was their adviser，consulting with them when the group encountered difficulties.Though they sought advice from English，math and science teachers，they were responsible for monitoring one another’s work and giving one another feedback.There were no grades，but at the end of the term，the students wrote evaluations of their classmates.The students also designed their own course.In addition to some regular courses，they each took on an “individual project”，learning to play the piano or to cook，writing a novel or making a video about domestic (国内的) violence.At the end of the term，they performed their new skills in front of the entire school.The last part of their self-designed course was to do a “collective project” that had social significance.Because they felt the whole experience had been so life-changing，they ended up making a film showing how other students could start and run their own schools.The project was a success.After returning to their traditional study，the students have high motivation and are doing well.One student who had failed all of his previous math courses spent three weeks teaching the others about probability.The lesson learned here is that if students are given the opportunity to take control or contribute significantly to their own learning they will become more accomplished，more engaged and more knowledgeable.The students in the project are remarkable because they demonstrate the kinds of learning and personal growth that are possible when teenagers feel ownership of their high school experience，learn things that matter to them and learn together.1．Which of the following statements is TRUE?A．Some students might drop out of high school.B．The teachers monitored the students’ homework.C．The students themselves solved all their problems.D．The teachers evaluate the students’ performances.2．The students involved in the Independent Project ________.A．didn’t need to learn common lessonsB．tended to escape from the whole societyC．were unwilling to share their experiencesD．focused on self-study and working together3．According to Paragraph 4，we know that ________.A．the traditional study is better than the projectB．all the students had failed their math coursesC．the students have freedom to design their lessonsD．the project was mainly concerned with math courses4．The project made the students outstanding because ________.A．they are unusually talentedB．they have better backgroundsC．they have supportive teachersD．they are owners of their education5．What would be the best title of the text?A．Structure the kids’ days to the minuteB．Let kids

人教版高一英语必修三Unit 4课文翻译Unit 4 Astronomy:the science of the stars —Reading—HOW LIFE BEGAN ON THE EARTH地球上生命的起源No one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a "Big Bang" that threw matter in all directions. After that, atoms began to form and combine to create stars and other bodies.没有人确切知道地球是怎样开始形成的，因为在很早很早以前它就形成了。
然而，一种普通为人们所接受的理论是：宇宙起源于一次大爆炸，这次大爆炸将物质投射到四面八方。
然后，原子开始形成并结合成恒星和其他天体。
For several billion years after the "Big Bang", the earth was still just a cloud of dust. 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. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even more important is that as the earth cooled down, water began to appear on its surface.大爆炸后好几十亿年过去了，但地球还只是一团尘埃。
