Step VII. Homework assignment
The 5th Period
Teaching Aims:
Improve the students reading skills.
Learn something about Copernicus and his Revolutionary Theory
Learn how to accomplish a persuasive writing.
Difficult and Important Points:
1)Reading Comprehension
2)Persuasive writing.
Teaching Methods:
Comparative method
Teaching Procedures:
Step I Warming up
1.Do you know what is the center of the solar system?
2.Can you name the nine planets in the solar system?
Mnemonics (记忆术)
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto
Can you use a good method to memorize them ?My Very Easy Method: Just Set Up Nine Planets.
Step II. Reading
Title of the passage: Copernicus’ Revolutionary TheoryFast reading
Listen to the tape, and find out the answers to the questions.
1. What did Copernicus think was the center of the solar system?
2.When did Copernicus publish his theory?Careful reading
Why didn’t Copernicus publish his theory before he died?
Step III. Reading comprehension
P7. 1.Use the reading to help you draw the two theories of the universe.
Before Copernicus’ theory
A diagram showing the solar system with the earth at its centre
Showing Copernicus’ theory
A diagram showing the solar system with the sun at its centre
Step IV. Persuasive writing (Please refer to P8 Learning Tip)
Writing Task: P7.3.Now writing a short letter asking Copernicus to publish his ideas so everyone can read them.
First you need to collect your ideas. For example:
?He believes his new theory is true.
?There are problems with the present theory.
?He has done many years of observations to prove his new theory is true.
?Science can’t develop unless people publish their ideas.
?Time will show if his theory is true or not.
Here is a plan:
Beginning: Tell Copernicus who you are and why you want him to publish his ideas.
Paragraph 1: Reason 1 and evidence.
Paragraph 2: Reason 2 and evidence.
Summing up: Ask him to think again about publishing his ideas.
One possible version:
Dear Nicolaus Copernicus,
I am a student studying astronomy and I would very much like to read your new theory about the solar system. I hope you will publish it for several reasons.
I understand the problems with the present theory. The way the planets move is not what you would expect if the earth was the centre of the universe. It is also odd that the brightness of some stars seems to change. So I agree with you that we need a new theory.
I know your observations have been very carefully carried out over many years. Now you must have the courage to publish them. Science can never advance unless people have the courage of their beliefs. I know you worry about what will happen if you publish your new theory. No matter how people oppose it, time will show if your ideas are right or wrong.
So I hope you will feel you can publish your new theory.
Yours sincerely,
Zhang Hua
Step V. Summary
Step VI. Homework assignment
1. Surf the Internet and get more information about Copernicus.
http://www.blupete.com/Literature/Biographies/Science/Copernicus.htm2. Revision
Nicolaus Copernicus was a Polish astronomer (1473-1543). Born in Torun, he began his university studies in Krakow in 1491, where he studied canon law and Latin and Greek classics. However he also had an interest in mathematics and astronomy. After obtaining his degree of Doctor of Canon Law (教会法规博士学位)in Italy in 1503, Copernicus returned home to Warmia in Poland to serve as Canon (=priest) .
In 1530, Copernicus completed his great work De Revolutionibus (《天体运行论》).Copernicus knew that these findings would lead him into trouble with the Roman Catholic Church (罗马天主教教徒), so he wasin no hurry to publish his theory. He only published it as he lay dying in 1543.
Though Copernicus did not live to hear of its extraordinary impact, the book which first suggested that the Sun, not the Earth, is the centre of the universe is now recognized as one of the most influential scientific works of all time. Adapted from http://www.library.rdg.ac.uk/colls/special/featureditem/copernicus

【教学反思】
学生通过对本单元的学习，了解到古今中外，涌现出的许多杰出的科学家，他们的充满智慧﹑博学多闻﹑呕心沥血﹑解决难题﹑证实观点的故事，使学生学到知识﹑尝到乐趣﹑获得智慧﹑受到鼓舞，从而有利于帮助学生培养科学精神，培养出科学人文精神相融合的创新型人才。
通过对 John Snow﹑钱学森﹑哥白尼的学习让学生对科学家的生活有所了解和感悟。此外在学习语言知识、训练语言技能、提高语言交际能力的同时，加强了对学生的品格素养的培养，也陶冶了学生的情操。
教师在教学中要尽可能多给学生时间、空间、机会，让学生通过自学、自做、自助、自悟，感悟和体验课文中所介绍的有关科学家的探索、发现的内容。教师不必过多过细的解释。同时，教师应注意将课堂内容向课外延伸。
当前语言教学新趋势要求教师在教学词汇时要避免按字典逐字逐句讲解的方法。在教授词汇时，要注意语境、语篇、语感、语用的结合，使学生在语境中学习词汇，在语篇中理解词意，在练习中增加语感，在实践中提高语用能力。
在小节课里面，组织学生搞句子接力赛这种游戏式的巩固练习，避免了语法复习中的枯燥乏味，培养了学生的合作学习精神，也加深了对过去分词作定语和表语用法的理解。

1) Archimedes (287—212 BC) Ancient Greek. He was a mathematician. He found that if you put an object into water the water pushes the object up. It rises and partly floats.
“Give me a place to stand on, and I can move the earth.” ----Archimedes
2) Charlie Darwin(1808-1882) British naturalist. The Origin of Species was published in 1859. It explained how plants and animals had changed over time to fit in with a changing environment. His book showed that people had developed from apes.
3) Gregor Mendel(1822—1884) Czech. The father of genetic. He grew pea plants and developed ideas on heredity (遗传) and inherited characteristics. Between 1856—1863 he grew 28,000 pea plants. He examined seven kinds of seed and plant characteristics and developed some laws of inheritance.
4) Marie Curie ( Polish ) (1867-1934) was born in Poland, moved to Paris and studied chemistry and physics there. She married Pierre Curie and together they studied radioactive materials and discovered radium. In 1911 she received the Nobel Prize in Chemistry. Her death in 1934 was almost certainly due to radiation in her work.
5) Thomas Edison(1847----1931) He was already an inventor of other electrical devices (phonograph, electric light bulb) when in 1882 he designed a system for providing New York with electricity from a central power station. This was a tremendous achievement, which had previously been thought impossible.
6) Leonardo da Vinci (Italian) (1452-1519)He was a famous Italian artist whose skill for showing human skin tones made his paintings seem to come alive. He used to study dead people in order to make his paintings as accurate as possible. Some of his famous paintings include “The Adoration of the Magi” and the “The Last Supper”. Later in his life he lived in France where he designed a submarine (潜水艇) and a flying machine.
7) British. He did research into different gases and discovered the medical value of nitrous oxide (laughing gas) as an anaesthetic.(麻醉药) In 1815 he developed a safety lamp for miners.
8) Zhang Heng ,Chinese( 78-----139) He invented the first seismograph to indicate in the direction of an earthquake. It was in the shape of a cylinder with eight dragonheads round the top, each with a ball in its mouth. Around the bottom were eight frogs directly under a dragon’s head. When an earthquake occurred, a ball fell out of the dragon’s mouth, making a noise.
9) Stephen Hawking,British(1942--- ) He has worked in astronomy and studied black holes in space. He has shown that black holes do not only absorb everything around them but, from time to time, throw out matter as well. This may mark the beginning of new galaxies. This is an advance on the old theory which said that black holes “eat” everything they come across.
Step 4 Pre-reading
1. (Pair work) What five most important qualities do you think a scientist should have? Give reasons.
clever/talented strict patient creative determined/strong-willed positive honest energetic intelligent/hard-working ambitious careful co-operative confident brave

1.Get 1-2 Ss to report to the class information of Copernicus
( Who is he? What achievement did he make? When? …)
2. Background Supplementary: Background
Nicolaus Copernicus was a Polish astronomer (1473-1543). Born in Torun, he began his university studies in Krakow in 1491, where he studied canon law and Latin and Greek classics. However he also had an interest in mathematics and astronomy. After obtaining his degree of Doctor of Canon Law (教会法规博士学位)in Italy in 1503, Copernicus returned home to Warmia in Poland to serve as Canon (=priest) .
In 1530, Copernicus completed his great work De Revolutionibus (《天体运行论》).Copernicus knew that these findings would lead him into trouble with the Roman Catholic Church (罗马天主教教徒), so he was in no hurry to publish his theory. He only published it as he lay dying in 1543.
Though Copernicus did not live to hear of its extraordinary impact, the book which first suggested that the Sun, not the Earth, is the centre of the universe is now recognized as one of the most influential scientific works of all time.

Aurora:　I’ve been in here all night.　I’ve been trying to decide what...what wedding gift to get you.　I thought of that Renior，that my mother gave me.　But I couldn’t reach a conclusion.　And then I came to grips with the reason why I couldn’t think of a wedding gift...for you.

What will you be doing when you are 26 years old，studying for your master’s degree or working for a living？ Take a look at what Albert Einstein was doing in 1905，when he was 26.This will help you understand why the United Nations declared 2005 the World Year of Physics in order to honour Einstein’s achievements 100 years ago.?
In 1905，Einstein was working in the Patent Bureau in Switzerland.　But his hobby was physics.　Without? much money or help，he published five papers in a professional physics magazine.　Three of these went on to have a huge impact in the study of physics.?
His most famous work is on the Theory of Relativity(相对论).Einstein said that measurements(度量)of time and distance change because everything moves relative(相对的)to everything else.　Space and time are not absolutely fixed and the universe(宇宙)we live in is not the one Newton “discovered”.　He proved that energy and matter(物质)are linked in the most famous? relationship in physics:　E=mc2.(The energy content of a body is equal to the mass(质量)of the body times the speed of light squared.)?
In another paper about Brownian motion(布朗运动)，he proved the existence of atoms(原子).The third big Einstein work was on quantum theory(量子论)of light.　The idea was that light exists as tiny particles(微粒).?
This was the most shocking idea in twentieth century physics:　we live in a quantum universe，one built out of tiny，individual(单独的)pieces of energy and matter.　Einstein was awarded the Nobel Prize for this discovery.?
Although Einstein achieved many other things later，1905 has been called the “miraculous year”(奇迹年)due to the importance of the three papers.?
On April 18，the 50th anniversary of Einstein’s death，a light signal will be relayed(接力) around? the world by volunteers spaced 10 kilometres apart.　It will start from Princeton，US，the last place where he lived and worked.　It will also come across China.　You will have a chance to participate(参与)in the event.?

How does a person get cholera?
A person may get cholera by drinking water or eating food contaminated （污染）with the cholera bacterium（细菌）. The disease can spread rapidly in areas with inadequate treatment of sewage（污水） and drinking water. The cholera bacterium may also live in the environment in polluted rivers and coastal waters. Shellfish eaten raw(生肉) have been a source of cholera, and a few persons in the United States have contracted cholera after eating raw or undercooked shellfish from the Gulf of Mexico. The disease is not likely to spread directly from one person to another; therefore, casual contact with an infected person is not a risk for becoming ill.
In January 1991, cholera appeared in South America and quickly spread to several countries. A few cases have occurred in the United States among persons who traveled to South America or ate contaminated food brought back by travelers.Cholera has been very rare in industrialized nations for the last 100 years; however, the disease is still common today in other parts of the world, including the Indian and sub-Saharan Africa. Although cholera can be life-threatening, it is easily prevented and treated. In the United States, because of advanced water and sanitation systems（卫生系统）, cholera is not a major threat; however, everyone, especially travelers, should be aware of how the disease is transmitted and what can be done to prevent it.
Copernicus' life
Many thought he was crazy. Others thought he was a genius. Some even thought he was the devil. This man's name was Nicolaus Copernicus. This man understood important things about our world, our solar system, and our universe.?Nicolas Copernicus was born in Torun, Poland, on February 19, 1473. He was the youngest of four children.???When Nicolaus was a young boy, just 10 years old, his father died. He and his brothers and sisters was brought up by his uncle, a prince-bishop（中世纪采邑之主教）, so he had the advantage of being able to get a first-class education. in 1491, Nicolaus went to the University of Krakow. The university was one of the greatest in Europe at the time.?Nicolaus later said that his studies at that university changed his life. At the university, he studied Latin, math, astronomy, geography, and philosophy.
Copernicus placed the sun in the center of the system and made the earth a planet traveling around the sun. Today it is hard to imagine our solar system any other way, but in his time Copernicus's idea was earthshaking.
It occurred to Copernicus as early as 1507, that tables of planetary positions could be calculated more easily if it were assumed that the sun, rather than the earth, were the center of the universe. This would mean that the earth itself, along with the other planets, would have to be considered as moving through space and revolving about the sun. This was not a new idea. Among the ancients, Aristarchus(阿里斯塔耳科斯) had suggested the notion, and not many years before the time of Copernicus, Nicholas of Cusa (尼哥拉) had made a similar suggestion.
Copernicus was to do more than suggest, however. Beginning in 1512, he set about working out the system in full mathematical detail in order to demonstrate how planetary positions could be calculated on this new basis. As it turned out, the Copernican system explained some of the puzzling motions of the planets. The orbit of Venus(金星), according to the new system, would naturally never take the planet farther than a certain distance from the sun, as viewed from the earth, because the orbit of the planet lay closer to the sun than did the orbits of the earth. On the other hand, since the earth would have to be considered as traveling in a smaller orbit than those of Mars, Jupiter(木星), and Saturn(土星), it would periodically overtake those planets and cause them to appear to be moving backward in the sky.
In 1616 the church banned his book Revolutions because it contradicted （与……发生冲突）the accepted notion that God placed the Earth in the center of the universe. Even though those who knew of his work considered his idea dangerous, Revolutions remained of interest to other scientists for many years. It took almost two hundred years for his concept of a sun-centered system to reach the general public. What Copernicus set out in his remarkable text truly revolutionized science. For this, Copernicus, a quiet doctor who made a tremendous leap of imagination, is considered the father of the Scientific Revolution.
