Read the following passage, and then tick the correct answers : T or F.
Many people still believe that natural resources will never be used up. Actually, the world's energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative sources of power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start saving coal, oil and gas before it is too late; and solar power is the only alternative.

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 such as 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?
__T__ 29/ Energy is used to produce a lot of electrical things.
__F__ 30/ Energy comes from natural resources.
_T___ 31/ burning fossil fuels causes pollution.
__T__ 32/ Everyone tries their best to find other kinds of energy for the future.

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.
