1 Passive form is used when:

- the doer is not known and not important

- the object is not important

2 If the doer is definite and still important, we can add “ by O ” at the end of the sentence.

Professor Galton

Renewable and non- renewable

energy

Act 2 Read the text below and check your ideas.

Dear guests, I’d like to talk to you today about renewable and non-renewable energy.

Fossil fuels are non-renewable energy sources They include oil, coal, and natural gas They can be used to create energy, generate electricity, or drive big machinery Unfortunately, they are harmful to the environment Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.

Hydro and nuclear power can generate a great deal of energy They are renewable and plentiful However, hydro power is limited because dams cannot

be built in certain areas Nuclear power can provide enough electricity for the world’s needs, but it is dangerous.

The sun and the wind are other alternative sources of energy The wind turns turbines to make electricity Solar power can be converted into electricity It can

be used to heat or cool our houses Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity They will be valued more and more in the future in Viet Nam.

1 How many types of energy sources are mentioned in the text? What are they?

2 What are the disadvantages of hydro and nuclear

power?

5 What does the professor think Vietnam will use more in the future?

3 Why do you think the wind and the sun are called

alternative sources of energy?

Fossil fuels

1 How many types of energy sources are mentioned in the text? What are they?

- Two, they are renewable and

non-renewable.

Paragraph 1: Dear guests, I’d like to talk to you today about

renewable and non-renewable energy.

2 What are the disadvantages of hydro and nuclear power?

- Hydro power is limited because dams cannot

be built in certain areas Nuclear power is

dangerous

Paragraph 3: Hydro and nuclear power can

generate a great deal of energy They are

renewable and plentiful However, hydro

power is limited because dams cannot be

built in certain areas Nuclear power can

provide enough electricity for the world’s

needs, but it is dangerous.

3 Why do you think the wind and

the sun are called alternative sources

of energy?

Because they are natural sources of power and we use them instead of non-renewable sources to get electricity we need

Paragraph 4: The sun and the wind are other

alternative sources of energy The wind turns

turbines to make electricity Solar power can be

converted into electricity It can be used to heat or

cool our houses Although there are some

disadvantages, these alternative energy sources can

offer abundant amounts of clean, safe electricity

They will be valued more and more in the future in

Viet Nam.

4 What types of energy does Vietnam use

most?

- We use non-renewable sources of energy the most but we are increasingly using hydro power.

Paragraph 2: Fossil fuels are non-renewable energy sources They

include oil, coal, and natural gas They can be used to create energy,

generate electricity, or drive big machinery Unfortunately, they are

harmful to the environment Viet Nam still relies mostly on

non-renewable energy sources, however, hydro power is increasingly used

here too

5 What does the professor think Vietnam will use more in the future?

- He thinks Vietnam will use the wind and the sun

as alternative sources of energy in the future

Paragraph 4: The sun and the wind are other alternative sources of

energy The wind turns turbines to make electricity Solar power

can be converted into electricity It can be used to heat or cool our

houses Although there are some disadvantages, these alternative

energy sources can offer abundant amounts of clean, safe electricity

They will be valued more and more in the future in Viet Nam.
