Nội dung text: Bài giảng Tiếng Anh Lớp 7 - Unit 10: Sources of Energy - Lesson 1: Getting started (Chuẩn kiến thức)

1. Trường THCS Đại Đồng Thành Giáo sinh: Ngô Thị Lụa
2. What types of energy do you know? Name of energy: energy
3. nuclear gas water Energy coal solar wind oil
4. Unit 10: SOURCES OF ENERGY Lesson 1: GETTING STARTED A different type of footprint
5. I. Vocabulary Dấu chân các bon Thải ra Không thể hồi phục Cạn kiệt Solar panel (n): Pin mặt trời Renewable (adj): Có thể phục hồi, tái tạo Environment (n): Môi trường
6. Carbon footprint – Dấu chân cacbon Dấu chân cacbon là lượng khí CO2 mà bạn đưa vào khí quyển. Nó được sinh ra bởi các hoạt động của con người Có thể em chưa biết ? Không phải là quốc gia xanh, xây nhiều nhà xanh, trồng nhiều cây xanh là có Dấu chân Carbon thấp. Ví dụ như : quốc gia được gọi là "Quốc đảo Xanh" Singapore lại đứng trong hàng top các quốc gia có mức phát thải khí CO2 cao nhất thế giới. Do đó, có thể thấy rằng, để có một quốc gia xanh bền vững đúng nghĩa, chúng ta cần phải làm nhiều thứ hơn.
7. Nam Mai 1.Who are they? 2.What are they talking about?
8. II. Listen and read: 1. Listen Mai: Nam, I read yesterday that we all have a carbon footprint. Nam: Well, we all have footprints–we make them with our feet! Mai: Ha ha, I know that. But this kind of footprint is about the negative effect we have on the environment. Nam: Right, it’s in the news a lot these days. Mai: So our footprint is bigger when we use energy that produces carbon dioxide. That’s bad for the environment. Nam: So it’s better to have a smaller footprint, right? Mai: Right, Nam. Non-renewable energy sources like coal, natural gas, and oil produce a lot of carbon dioxide .Those sources are going to run out soon, too. Nam: So, they’re different to wind, hydro, and solar? Mai: Yes, they’re all sources of energy too, but they’re renewable. That means they can use them all up – They will last forever. Nam: Do you have a big carbon footprint, Mai ? Mai: Mine’s small. I recycle the products I use and I go everywhere by bike. We have solar panels on our roof at home to catch the sun’s energy, too. Nam: Oh no! I think my footprint is big, and not just because of these big shoes!
9. 1. a. Read the conversation again and answer the questions 1. What is a carbon footprint? It’s about the negative effects we have on the enviroment. 2. What does 'non-renewable energy' mean? Non- renewable energy means that it will run out if we use it. 3. Why is sunlight a renewable source? Sunlight is a renewable source because we can’t use it all up or it will last forever. 4. Why does Mai think she has a small carbon footprint? Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike. 5.What things do you think might create a big carbon footprint? The products that we use are bad for the enviroment or the energy that we use produces carbon dioxide might create a big carbon footprint .
10. b. Complete the network below using information from the conversation. Sources of energy Renewable sources Non -renewable sources
11. wind coal natural gas nuclear biogas oil hydro solar
12. b. Complete the network below using information from the conversation. Sources of energy Renewable Non -renewable sources sources nuclear oil wind hydro biogas coal natural gas solar
13. 4. Practise asking and answering the questions about renewable and non-renewable sources. Example: A: What type of energy sources is wind? B: It’s a renewable source of energy. A: What type of energy source is coal? B: It’s a non-renewable source.
14. 1. Learn by heart vocabulary introduced in the lesson. 2. Re-read the dialog. 3. Write a paragraph: how to reduce carbon footprint. 4. Prepare new lesson : Unit 10. A closer look1.
