Our environment is in trouble. People and industries are polluting the air, rivers, lakes and seas. There are many things you can do to help the environment. Here are a few.

Firstly, the burning of petroleum is one of the biggest sources of carbon monoxide (CO) that causes global warming. CO thins the ozone layer, which protects us from the sun’s ray. So try to walk, cycle or use public transportation.

       Secondly, the biggest use of home energy is for heating and cooling homes. It not only consumes much energy but also costs a lot of money. So turn the heat down, especially at night. Replace ordinary light bulbs with energy-saving light bulbs, which use less energy.

Finally, showers use a lot of water. Buying a special “low-flow” shower head or taking shorter showers can cut this use in half.

25.False

26.True 

27. False

28. True 

29. The passage mainly discusses:

a. The source of CO 

b. Energy-saving bulbs

c. The ozone layer

d. Some ways to protect the environment

30. The word “ordinary” in line 6 is closest in meaning to the word:

a. modern b. cheap c. effective d. normal

Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.

VI. Read the text then answer true or false

People use many sources of energy. Ancient people used only their arms, hands, and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the eighteenth and nineteenth centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water turned into steam, and the steam engine did the work. Later, people began to use the gasoline engine, and today people are using nuclear energy. Energy is one of the basic concepts, or ideas, of physics. It is the ability to do work. Without energy we could live. We need energy to work, and scientists are always looking for new sources of energy.

1. None of the world’s energy comes from the sun. F

2. Wind, steam, and gasoline are sources of energy. T

3. People have never used nuclear energy. F

4. Energy is the ability to do work. T

5. We need new sources of energy. T
