VII.  Read the passage and choose the best option (A, B, or C) to complete each sentence.

We can use renewable and non-renewable energy sources to make electricity.

Most of our electricity comes from power stations that use fossil fuels like coal, oil and gas. We call them non-renewable sources because they will eventually run out. Unfortunately, burning fossil fuels produces lots of greenhouse gases which cause global warming.

We also use renewable energy sources like the sun, wind and water to make electricity. We can use them again and again because they cannot run out. They do not produce greenhouse gases so they are much less harmful to the environment.

1.  Power stations use fossil fuels like    to produce electricity.

A.  coal, oil and gas    B. coal and gas     C. oil and gas

2.  Burning fossil fuels produces   which cause global warming.

A.  greenhouse gases B. carbon dioxide  C. methane

3.  We can use the     to make electricity.

A.  sun and water       B. sun and wind    C. sun, wind and water

4.  The renewable sources can be used again and again because they                                   .

A.  can run out           B. cannot run out   C. should run out

5.  Renewable sources are harmful to the environment.

A.  much more            B. much less         C. not less

VIII. Complete the passage with appropriate phrases in the box.

causing climate change      walk or cycle      low energy light bulbs 

powering our appliances          turn off the lights

We use energy for almost everything we do: for heating our homes, cooking our meals and (1)                   The use of energy is (2)                   worldwide. It is responsible for many recent floods, droughts and storms.

What should we do to avoid these problems? Firstly, we should (3)                               before going to bed or when going out. Secondly, we should use (4)                              at home.

Thirdly, we should (5)      to school. In conclusion, we should use energy more wisely for our future.
