 1. 
 Energy is very important in modern life. People use energy to run machines, heat and cool their homes, 
 cook, give light, transport people and products from place to place. Most energy nowadays comes from 
 fossil fuels –petroleum, coal, and natural gas. However, burning fossil fuels causes pollution. Also, if 
 we don’t find new kinds of energy, we will use up all the fossil fuels in the twenty first century. 
 Scientists are working to find other kinds of energy for the future. What might these sources of energy 
 be?
 1.______________ Energy is collected for use in their homes.
 2.______________ We burn coal to produce electricity.
 3.______________ Air pollution comes from the burning of fossil fuels.
 4.______________ Scientists aren’t doing research into alternative energy sources.
 2. 
 When man first learned how to make a fire, he began to use fuel for the first time. The first fuel he used 
 was probably wood. Coal was not used very widely as a source of energy until the last century. With 
 the coming of of the industrial revolution, it was soon realized that production would double if coal was 
 used instead of wood. Nowadays, many of the huge factories and electricity generating stations would 
 be unable to function if there were no coal. In the last twenty or thirty years, however, the use of coal 
 has declined. As a result, there have been changes in the coal industry. It is believed that more people 
 would use coal if oil and gas were not so readily available.
 1._____________ Man used wood as the first fuel.
 2._____________ Coal was used widely in the last century.
 3. ____________ Coal is very important for factories and electricity generating stations.
 4. ____________ There have been no changes in the coal industry.

3. Why don’t you ask her yourself? 19. Mrs Ha has asked a plumber to check the pipes in her house.
 Mrs Ha has had ______________________________________.
