老师：Hello my dear students. I'm an English teacher from Leyang Senior High. Nice to meet you here. Today's tasks are to discuss some scientists that have changed the world and to learn how to make a fact file about the scientist through cooperation and exploration. Now comes the first task. Discuss about scientists. What does a scientist do? A scientist is someone who has she studied science and whose job is to teach or do research in science. Have you dreamed of becoming a scientist in the future? Who do you think is likely to become a scientist in your class and why? Different scientists are expert in different fields.
老师：Here are some categories of science. Let's have a look. The study of animals is called zoology. The study of plants is called Courtney. The study of all living things is called biology. The signs of numbers and shapes is called maths or mathematics. The study of physical objects and natural forces is called physics. The study of chemical processes in living things is called biochemist. The study of structure of substances and how they react with each other is called chemistry. And the study of inherited characteristics in living things is caught genetics. And students, people who study it are caught. Zoologists, botanists, biologists, mathematicians, physicists, biochemists, chemists and generatists respectively students. There are so many great scientists across the world. Do you know about some? For example, who invented the first modern steam engine. He is James what? Who defeated King Cholera. He is Jim Snow, who is the inventor of electric light bulb. Yes, Thomas Edison, who invented the earliest instrument to tell people where earthquakes happened.
老师：Zhang Heng, right? And more examples in detail. Let's see. Think about it. He is Qinchuan, a Chinese. He majors in physics. And he invented Chinese atom bomb in 1964. The second is a woman. Who is she? She is Marie Curie, a Polish, and she majors in physics. She discovered radio activity in 1898. And third one, he is Yuan Longping, also a Chinese. He majors in agriculture. And he discovered a new kind of rice that is hybrid rice in 1970.
老师：So you see, this is actually a simple fact file, which is what we are going to make in this class. What is effect file? Let's see. Affect file is a collection of information that can be proved to be true, for example, about a particular person or subject. Then how to make effect file? Okay, let me show you an example on page 55. As you can see, it is composed of a photo of a scientist and also some relevant facts, including personal information, achievements, influence, and interesting fact.
老师：Now let's try to make a fact file about 2 Yoyo together. Actually, we have Learned a lot about this great scientist. Now, let's review. Som
