Trang 15Who are they? What are they talking about? What is a different type of footprint?
Trang 17M: Nam, I read yesterday that we all have a
carbon footprint.
N: Well, we all have footprints – we make them with
our feet!
M: Ha ha, I know that But this kind of footprint is about
the negative effect we have on the environment.
N: Right, it’s in the news a lot these days.
M: So our footprint is bigger when we use energy
that produces carbon dioxide That’s bad for the environment.
N: So it’s better to have a smaller footprint, right?
Trang 18M: 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.
N: So, they’re different to wind, hydro, and solar?
M: 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.
N: Do you have a big carbon footprint, Mai?
M: 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 N: Oh no! I think my footprint is big, and not just
because of these big shoes!

Trang 334 Practise asking and answering the questions
about renewable and non renewable sources.
A: What type of energy source 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.
Trang 34Yes, through the lesson you can now name some types of energy sources;
we can use words to describe energy sources; we can also distinguish what types are good/bad for environment;.
Please tell me what you have
learnt today
Trang 35- Learn the new words by heart.
- Practice the dialogue again.
- Do exercises B1 in workbook (page 30).
- Prepare for Unit 10: A closer look 1.
