Bài giảng English 7 - Unit 10: Sources of Energy - Lesson 1: Getting started
Listen and read:
Mai: Nam, I read yesterday that we all have 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 are different to wind, hydro, and solar?
Mai: Yes, they’re all sources of energy too, but they’re renewable. That means we can’t 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!
Read the conversation again and answer the following questions.
1. What is a carbon footprint?
2. What does “non-renewable energy” mean?
3. Why is sunlight a renewable source?
4. Why does Mai think she has a small carbon footprint?
5. What things do you think might create a big carbon footprint?
