Part 2: Read the passage and answer the questions.
We can develop alternative sources of energy, and unless we try we’ll never succeed. Instead of burning fossil fuels we should be concentrating on more economic uses of electricity, because electricity can be produced from any sources of energy.
If we didn’t waste so much energy, our sources would last longer. We can save more energy by conservation than we can produce for the same money. Unless we do research on solar energy, wind power, tidal power, hydroelectric plants … our fossil fuels will run out and we’ll all freeze or starve to death.
Many countries are spending much more time and money on research because the energy from the sun, the waves and the winds last forever. We really won’t survive unless wa start working on cleaner and safer sources of energy.
1, Can electricity be produced from any sources of energy?
____________________________________________________________________.
2, What would happen if we didn’t waste so much energy?
____________________________________________________________________.
3, Why are many countries spending much more time and money doing research on energy from the sun, the waves and the wind?
____________________________________________________________________.
4, What will happen unless we start working on cleaner and safer sources of energy?
____________________________________________________________________.

Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on house roofs, so no new space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages. Wind and water power rely on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime. However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cells require large area to work effectively. The main disadvantage of solar energy is that it costs about twice as much as traditional sources such as coal, oil and gas. This is because solar cells are expensive. Scientists are hoping that the costs of solar cells will reduce as more and more people see the advantages of this environmentally friendly source of energy

VI. Read the passage and decide ì the sentence is True (T) or False (F). (1 pt)
There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – therefore we call them fossil fuels. Fossil fuels take millions of years to make. But they are not unlimited. We are using up the fuels that were made more than 300 million years ago. They are not renewable like solar power, wind power, hydro power or biomass. Once they are gone they are gone. So, it’s best not to waste fossil fuels. We can save fossil fuels by conserving energy. One simple way to do this is to turn off appliances, TVs and radios that we are not using. We can also turn off lights when no one is in the room. Another way is to go by bike or walk instead of driving cars or motorbikes. * True (T) or False (F): |
1. Three major forms of fossil fuels are oil, coal and natural gas. |
2. They were formed right after the time of dinosaurs. |
3. Once fossil fuels are gone, they will come back later. |
4. Hydro power and biomass are non-renewable sources. |
