Read the following passage carefully and answer the questions. We can develop alternative sources of energy, and unless we try, we will never succeed. Instead of burning fossil fuels we should be concentrating on more economical use of electricity, because electricity can be produced from any sources of energy. If we didn’t waste so much energy, our resources 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 will all freeze or stave 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 we start working on cleaner and safer sources of energy. Questions: 36. What can electricity be produced from? 37. What would happen if we didn’t waste so much energy? 38. What will happen unless we do research on solar energy and other alternative sources of energy?
