Unit 1 Science and Scientists Listening and Speaking 课件 -【大单元教学】高中英语同步备课系列(人教版2019选择性必修第二册）

Talk about scientific experiences Unit 1 Listening and Speaking Look at the photos below, and discuss in groups what these activities have to do with science. What can you see in the picture? What is he/she doing? Why is he/she doing that? Warming -up a giant dish whisper I think the dish in this exhibition is related to sound. Maybe the boy is whispering into the smaller circle and the dish can make his voice louder. This looks like a piano you play with your feet. Maybe it shows how sound works. a piano keyboard play with feet I’m not sure what this one shows, but it must be about light or eyesight. a blue screen bright lights It is a hall of mirrors. Maybe it has to do with the principles of reflection. a hall of mirrors reflect This is probably an experiment involving the composition of light. a white light cast shadows in the colour of the rainbow Predict by using pictures One way to get more out of your listening is to predict what you will hear. Using the pictures provided and the knowledge you already have, you can guess the kinds of information you should listen for. At times, you may even be able to guess exactly what will be talked about. This will help you focus better when listening, making your listening more effective. Activity 2 Using the photos, try to predict the answers to the following questions. 1. Where are the people in the conversation going to go? 2. What kind of place is it, and what does it focus on? 3. What kinds of things can you do there? 1. Where are the people in the conversation going to go? A science museum/centre. 2. What kind of place is it, and what does it focus on? A place for delight, education and inspiration. It focuses on letting visitors experience science. 3. What kinds of things can you do there? Try different interactive(adj.互动的) activities to experience sound, light, reflection and so on. Activity 1 Write down the letters (A—E) for the photos in the order that you hear them. 1 ________ 2 ________ 3 ________ 4 ________ 5 ________ D C E B A While-listening a hall of mirrors see myself reflected thousands of times a blue screen tiny bright lights blood cells 1 2 a white light cast different shadows in every colour of the rainbow a giant piano keyboard use your feet to play play voices of classical singers 3 4 a giant dish reflect the sound back speak in a whisper to someone 17 metres away 5 Listen again and complete the descriptions of the photos above. Photo A: A giant dish; when you speak into it, it ________ the sound back and _______________. You can use it to speak in a ________ to someone 17 metres away. Photo B: A giant ________________ that you can use your feet to play. Instead of playing the sounds of a piano, it plays the voices of ________________. Photo C: You look at a blue screen for a while, and then suddenly you can see ________________ moving around on it. These are our _______________.

Photo E: You stand in front of ____________, and it casts different shadows of you, in _______________ the rainbow. reflects makes it louder whisper piano keyboard classical singers tiny bright lights own blood cells hall of mirrors a white light every colour of 1. The conversation is about the City of Science and Industry, a museum in Paris. Would you like to go to this museum? Why or why not? Discuss the following questions in groups. 位于巴黎东北部的“科学与工业城”据说是世界上最大、访问人数最多的博物馆之一，同时也是欧洲最大的科普中心。博物馆于1986年对外开放，科学城空间功能分4个部分：永久性陈列（地球宇宙、生命奥秘、物质人类、语言 交流），最新科技成果和工业产品（包括幻影式战斗机和啊丽亚纳火箭和空间站），图书资料中心，底层会议中心。其中还包括3D电影院、水族馆、植物园和众多新科技产品。 What can you do in the City of Science and Industry? What do you like most about it? 2. Are there any museums like this in China? What other interesting museums are there? Have you ever been to such a museum in China? Where is it? What is it like? What did you do there? In groups, choose one of the museum activities on the previous page or brainstorm another scientific research or experiment that you are interested in. Make a short presentation to the class about your choice. Use the example and useful phrases below to help you. Talking Practice Let’s talk about scientific phenomena Today, I want to talk to you about a very strange phenomenon called a non-Newtonian fluid. You can make it easily using equal parts of water and cornflour, like I have here. A non-Newtonian fluid is strange because you can pour it like a liquid, but if you put any pressure on it, it suddenly becomes hard as concrete. In fact, it becomes hard enough to stand on. Then, as soon as you take the pressure off, it becomes a liquid again. This show that it is possible that something can exist as a liquid and a solid at the same time.
