2019-2020年高中英语第二册上Makingadifference(1)Period 1 (Unit 1 BII) Warming up & Listening & Speaking I. Warming up 1. Introduce some famous scientists. The German-American physicist Albert Einstein, b. Ulm, Germany, Mar. 14, 1879, d. Princeton, N.J., Apr. 18, 1955, contributed more than any other scientist to the 20th-century vision of physical reality. In the wake of (随着.而来) World War I, Einsteins theories-especially his theory of relativity-seemed to many people to point to a pure quality of human thought, one far removed from the war and its aftermath. Seldom has a scientist received such public attention for having cultivated the fruit of pure learning. MARIE CURIE opened up the science of radioactivity（放射能）. She is best known as the discoverer of the radioactive elements（元素） polonium（钋） and radium（镭）and as the first person to win two Nobel prizes. For scientists and the public, her radium was a key to a basic change in our understanding of matter and energy. Her work not only influenced（影响） the development of fundamental （基础的）science but also ushered（引导）in a new era（纪元） in medical research and treatment. Alfred North Whitehead (b.1861 - d.1947), British mathematician, logician and philosopher best known for his work in mathematical logic and the philosophy of science. In collaboration with Bertrand Russell, he authored（创造） the landmark（里程碑） three-volume Principia Mathematica (1910, 1912, 1913) and contributed significantly to twentieth-century logic and metaphysics（形而上学）. At the time that Galileo arrived at the University, some debate had started up on one of Aristotles laws of nature-namely, that that heavier objects fell faster than lighter objects. Aristotles word had been accepted as gospel truth, and there had been few attempts to actually test Aristotles conclusions by actually conducting an experiment! According to legend, Galileo decided to try. He needed to be able to drop the objects from a great height. The perfect building was right at hand-the Tower of Pisa, 54 meters tall. Galileo climbed up to the top of the building carrying a variety of balls of varying size and weight, and dumped them off of the top. They all landed at the base of the building at the same time (legend says that the demonstration was witnessed by a huge crowd of students and professors). Aristotle was wrong. Who were they? What were they famous for? Scientists Contributions Quotes Meaning Albert Einstein the Theory of Relativity Imagination is more important than knowledge. If we weren t able to use out imagination, knowledge would simply be a useless collection of facts . Marie Curie discovery of radium and polonium Nothing in life is to be feared. It is only to be understood. We must not be afraid of the unknown. Once we understand something, there is no need to be afraid. Thomas Alva Edison invention of light bulbs Genius is one percent inspiration and ninety-nine percent perspiration. Great thoughts and ideas are the result of hard work, not sudden spurts of “inspiration”. Alfred North Whitehead It takes a very unusual mind to undertake analysis of the obvious. Most of us do not question the things we take for granted. Great scientists are enormously curious and tend to ask questions that others would never think of. Galileo Galilei You cannot teach a man anything; you can only help him find it within himself. There is a big difference between learning and teaching. 2. Read the quotes, What do they mean? Do you agree? 3. Discussion Any other great scientists and their contributions? Any other quotes about science and thinking? 4. What makes a scientist successful? （creative, hard-working, curious, careful, confident） II. Listening 1. Ask the students to guess the names of three well-known scientists. 2. Ask the students to write a brief paragraph about themselves. III. Speaking 1. Warming-up Give my own point of view towards a language and try to get the students to express their ideas and debate with them. I think that English is the most important language in the world. What do you think? 2. Go through the useful expressions on P2. Teach them to use these expressions in the dabate. 3. Divide the class into groups of 4. Each group discusses one branch of science. Make some notes if necessary. Why do you think is the most important and useful to society? 4.
