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

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.
2. We don't know exactly how much fuel is left.
3. We shouldn't waste natural resources.
4. We should find out other types of energy besides fossil fuels.
5. According to Professor Marvin Burnham, solar energy will be used as a form of alternative energy.

Alternative sources of energy
In the " Search for Free Energy", Tutt's recently released book, he quotes " We ought to be able to obtain the energy we need without the consumption of material." These are not the words of some modern-day environmentalist, but of Nikola Tesla, in 1890. Among his invention was the device to generate electricity by harnessing "coming energy". The search for free, and expensive energy continues. Researchers are looking for "fuelless" technologies that will not pollute or run out, and they are not referring to the puny contribution of solar or wind power. The science establishment has so far been proven correct, there's no such thing as a free energy lunch but that hasn't stopped mad scientists trying. They've come up with numerable patents of "over unity" contraptions, supposed giving out more energy than you put in to get them going. The story is fascinating and rarely heavy-going, although the quotes can be overlong and the diagrams are adequately displayed. Tutt admits that only a fraction of what is claimed is true. But it's also true to say we cannot afford to dismiss them out of hand, as one of these conforming investigators may just be able to save our planet from climate change.

II/ Read the text and choose the best answers A, B, C or D. to the questions. (1m)
Most of the countries in the world have searched for alternative sources of energy in various directions. Many communities are burning garbage and other biological waste products to produce electricity. Converting waste products to gases or oil is also an efficient way to dispose of waste.
Experimental work is being done to derive synthetic fuels from coal, oil, shale and coal tars. But today that process has proven expensive. Other experiments are underway to harness power with giant windmills. Geothermal power heat from the earth is also being tested.
Some experts expect utility companies to revive hydroelectric power 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 five percent. The oceans are another potential source of energy. Scientists are studying ways to convert the energy of ocean currents, tides, and waves to electricity. Experiments are also underway to make use of the temperature differences in ocean water to produce energy.

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.
