mentioned in the text?
3.Which source of energy do you think has
the most potential? and why?

1.What is our major source of energy ?

Our main source of energy
comes from fossil fuels.

2. How many sources of energy are mentioned
in the text ?

Five sources of energy are mentioned in the
text.
(They are: nuclear power, geothermal heat,
wind power, water power, solar energy.)

3.Which source of energy do you think has
the most potential? and why?

I think solar energy is the most potential
because It's not only plentiful
and infinite but also
clean and safe.

What should we do to save energy?

- Reduce our electricity bills (Giảm hóa đơn điện của chúng

ta)

- Increase the tax on petrol (Tăng thuế xăng dầu)
- Reduce the use of fossil fuels (Giảm sử dụng nhiên liệu hóa

thạch)

- Use more renewable energy (biogas, wind energy, …) (Sử

dụng nhiều năng lượng có thể tái tạo hơn (khí sinh học, năng lượng gió
…)

We should turn the light, the television and other electrical
appliances off when we are not using them. We can also use
low energy light bulbs to save electricity. …

We should travel by bike or bus instead of car and motorbike for
short trips. …
we should reduce the use of water. Taking showers instead of
baths is a good way. Besides, we should turn off the tap when
brushing our teeth… 

-Learn by heart the new words.
- Complete the after you read.
- Prepare

for the Speaking lesson.
