Unit 1Great scientistsBrief Statements Based on This UnitThis unit centers on Great scientists, including some scientists both at home and abroad likeJohn Snow and Copernicus.The students should be encouraged to practise talking about thesescientists.The whole unit can be divided into seven parts: warming up, reading, listening and speaking,In warming up, there is a quiz for the students to do, which will arouse the students’ intere in knowing about the famous scientists and help the students to know science is very important inour daily life.Group discussion and brainstorming will be used in this period to help the studentsto communicate with each other using their previous knowledge.In the reading passage, the students will learn about John Snow, who defeats“King Chole and get a general idea about how to examine a new scientific idea.This will help the students toform their own attitude towards science.In learning about language, the students are encouraged to learn the following words andexpressions: engine, characteristic, radium, theory, scientific, examine, conclude, analyze repeat,defeat, attend, expose, cure, control, absorb, severe, valuable, blame,

unit centers on“great scientists”．students should be encouraged to give their previous knowledge of some of the famous scientists, participate in the activities in class and try to get more information from the discussion.They willtake part in different forms of activities, including pair work, group work, competition, and Words and expressions in this unit will help the students to talk about the topic“great scientists”.Soat the beginning of this period, the teacher should spend some time training the students to read them and help the students pronounce them correctly.The students are encouragedto learn the new words in groups by themselves, using dictionaries and other reference books.Then more time should be given to the students to get familiar with the words and stly, several sentences will be given to the students to help them to know how to use some of the phrases.so from the very beginning, the teacher can This unit is about“great scientists”,students brainstorm something about great scientists.The students are free to say anything that they know.The students will be quite interested in this topic.This activity gives the students a chance to express their feelings about their favorite scientist.At the same time, this activity can stirthe students’ enthusiasm in science.Then the teacher can have the students match the famous scientists with their discoveries, inventions or theories, making sure that they have some common sense about some world-famous scientists.and let other students guess who he or she is talking about.In this way, the students should learn to After that, the students will feel comfortable to do the quiz in the text.The students should beMeanwhile, the students’ interest in scientists and science should be

Darwin published The Origin of Species byMeans of Natural Selection in 1859, sparking decades of contentious debate which ultimately ledto the universal scientific recognition of Darwin’s thesis.In later years, he developed his ideasfurther in monographs on different types of plant and animal life.Notes:Shrewsbury: 什鲁斯伯里[英国英格兰西部城市physician: 内科医生(注意区分physicist, 物理学家revolutionary: 创新的HMS: （英国）皇家海军舰船treatises: 论文2.Stephen William Hawking was born on 8 January 1942 (300 years after the death of Galileo)house was in north London, but during the Second World Warin Oxford, Engl and.His parents’　Oxford was considered a safer place to have babies.When he was eight, his family moved to StAlbans, a town about 20 miles north of London.At eleven Stephen went to St Albans School, andthen on to University College, Oxford, his father’s old college. Stephen wanted to do Mathematics, although his father would have preferred medicine.Mathematics was not available at UniversityCollege, so he did Physics instead.After three years and not very much work he was awarded afirst class honours degree in Natural Science.Stephen then went on to Cambridge to do research in Cosmology, there being no-oneworking in that area in Oxford at the time.His supervisor was Denis Sciama, although he hadhoped to get Fred Hoyle who was working in Cambridge.After gaining his Ph.D.he became first aResearch Fellow, and later on a Professorial Fellow at Gonville and Caius College.After leavingthe Institute of Astronomy in 1973 Stephen came to the Department of Applied Mathematics andTheoretical Physics, and since 1979 has held the post of Lucasian Professor of Mathematics.Thechair was founded in 1663 with money left in the will of the Reverend Henry Lucas, who hadbeen the Member of Parliament for the University.It was first held by Isaac Barrow, and then in1663 by Isaac Newton.Stephen Hawking has worked on the basic laws which govern the universe.With RogerGeneral Theory of Relativity implied space and time wouldPenrose he showed that Einstein’shave a beginning in the Big Bang and an end in black holes.These results indicated it wasnecessary to unify General Relativity with Quantum Theory, the other great Scientificdevelopment of the first half of the 20th Century.One consequence of such a unification that hediscovered was that black holes should not be completely black, but should emit radiation andeventually evaporate and disappear.Another conjecture is that the universe has no edge orboundary in imaginary time.This would imply that the way the universe began was completely His many publications include The Large Scale Structure of Spacetime with G F R Ellis,General Relativity: An Einstein Centenary Survey, with W Israel, and 300 Years of Gravity, withW Israel.Stephen Hawking has two popular books published: his best seller A Brief History of Professor Hawking has twelve honorary degrees, was awarded the CBE in 1982, and wasmade a Companion of Honour in 1989.He is the recipient of many awards, medals and prizes and Stephen Hawking continues to combine family life (he has three children and one grandchild),and his research into theoretical physics together with an extensive programme of travel andpublic lectures.3.Humphry Davy, a woodcarver’s son, was born in Penzance in 1778. After being educated inTruro, Davy was apprenticed to a Penzance surgeon.In 1797 he took up chemistry and was takenon by Thomas Beddoes, as an assistant at his Medical Pneumatic Institution in Bristol.Here heexperimented with various new gases and discovered the anesthetic effect of laughing gas (nitrousoxide).Davy published details of his research in his book Researches, Chemical and Philosophical(1799).This led to Davy being appointed as a lecturer at the Royal Institution.He was a talented In 1806 Davy published On Some Chemical Agencies of Electricity. The following year hediscovered that the alkalis and alkaline earths are compound substances formed by oxygen unitedwith metallic bases.He also used electrolysis to discover new metals such as potassium, sodium,leading scientist and in 1812 was knighted by Davy was now considered to be Britain’sGeorge Ⅲ.With his assistant, Michael Faraday, Davy travelled abroad investigating his theory of In 1815 Humphry Davy invented a safety lamp for use in gassy coalmines, allowing deep coal seams to be mined despite the presence of firedamp (methane).This led to some controversyas George Stephenson, working in a colliery near Newcastle, also produced a safety lamp that One of Davy’s most important contributions to history was that he encourage manufacturers to take a scientific approach to production.His discoveries in chemistry helped to improve several industries including agriculture, mining and tanning.Sir Humphry Davy died in 1829.4.Leonardo da Vinci(b.1452, Vinci, Republic of Florence [now in Italy]—d.May 2, 1519, Cloux, Fr.), Italian painter, draftsman, sculptor, architect, and engineer whose genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal.His Last Suppe (1495-1497) and Mona Lisa (1503-1506) are among the most widely popular and influential paintings of the Renaissance.His notebooks reveal a spirit of scientific inquiry and a mechanical5.Madam Curie is a French professor of physics.She was born in Poland in 1867.In 1891 she went to study in Paris University because at that time women were not admitted to universities in Poland.When she was studying in Paris, she lived a poor life, but she worked very hard.In 1895she married Pierre Curie, and then they worked together on the research into radioactive matter.They discovered two kinds of radioactive matter—polonium and radium.In 1904 she and her husband were given the Nobel Prize for physics.In 1906 Pierre died, but Marie went on working.She received a second Nobel Prize for Chemistry in 1911.So she became the first scientist in the world to win two Nobel Prizes.6.James Watt: British engineer and inventor who made fundamental improvements in the steam engine, resulting in the modern, high-7.Gregor Mendel was an Austrian botanist and founder of the science of genetics.Through years of experiments with plants, chiefly garden peas, he discovered the principle of the8.Archimedes: Greek mathematician, engineer, and physicist.Among the most important intellectual figures of antiquity, he discovered formulas for the area and volume of various geometric figures, applied geometry to hydrostatics and mechanics, devised numerous ingenious mechanisms, such as the Archimedean screw, and discovered the principle of buoyancy.9.Michael Faraday (September 22, 1791—August 25, 1867) was a British scientist(a physicist and chemist) who contributed significantly to the fields of electromagnetism and electrochemistry. He also invented the earliest form of the device that was to become the Bunsen Michael Faraday was one of the great scientists in history.Some historians of science refer to him as the greatest experimentalist in the history of science.It was largely due to his efforts that electricity became a viable technology.The SI unit of capacitance, the farad(symbol F) is namedafter him.。
