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.

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

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

3. We shouldn't waste natural resources. T

4. We should find out other types of energy besides fossil fuels. T

5. According to Professor Marvin Burnham, solar energy will be used as a form of alternative energy. F

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.
