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.
1. Natural resources will never run out. F
2. We don't know exactly how much fuel is left. T

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
Check True or False
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.

II/
Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from our sun. At present, most of our electricity comes from the use of coal, and gas, oil or nuclear power. This power could be provided by the sun. One percent of the solar energy that reaches the earth is enough to provide power for the total population. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the sun s energy is used to heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy, too.

Question II. Read the passage and answer the questions below
The search for alternative resources of energy has resulted in various directions. Many communities are burning garbage and other biological waste products to produce electricity. Changing waste products into gases or oil is also an efficient way to dispose of waste. Experimental work is being done to make synthetic fuels from coal, or coal tars. But to date, that process has proved expensive. Other experiments are underway to harness power with giant windmills. Geothermal power, heat from the earth, is also being tested.
Some experts are trying to revive hydroelectric power which is derived from streams and rivers. Fifty years ago, hydroelectric power provided one third of the electricity used in the United States, but today it supplies only four per cent. The oceans are another source of energy. Scientists are studying ways to change the energy of ocean currents, tides, and waves into electricity. Experiments are also underway to make use of temperature differences in ocean water to produce energy.
1. What are many communities doing to produce electricity?
........Many communities are burning garbage and other biological waste products to produce electricity.........
2. Has the process of making synthetic fuels from coal, or coal tars proved cheap?
