X. Read the passage, and choose the correct answer A, B, C or D for each question.
Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no oil, coal and gas on the earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water.
Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperate of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source od power.
1. From which do plants on the earth get energy?
A. stars B. the Mars C. the moon D. the sun
2. What are the other words or phrase for fossil fuels?
A. natural gas B. oil C. coal D. oil, gas, natural gas
3. Natural sources of energy are energy from .
A. wind B. the sun C. water D. the sun, wind, water
4. The word “abundant” in the passage is closet in meaning with .
A. plentiful B. limited C. natural D. necessary
5. We are asking the question, “What will happen when there is no oil, coal, and gas on the earth?” because .
A. we are now depending so much on oil, coal, and natural gas
B. other sources of energy can come from the sun, wind, and water
C. we are looking forward to seeing great changes
D. we are looking for other alternative sources of energy
XI. Read the passage and write T (True) or F (False) next to the sentences.
Solar energy
Solar energy is the energy that we get from the sun and converted into thermal or electrical energy. Solar energy is a renewable energy because it will never end as long as the sun remains. Solar energy is also pollution-free because there will be no pollution occurring while producing solar energy. Solar energy is not only pollution-free energy but also its maintenance cost is very low, so to maintain a solar power plant, less manpower is required than others. Also, one can get a non-stop power supply even in the rainy season with the help of solar panels. However, there are also some disadvantages of using solar energy like the initial setup cost of panels and battery is very high. To store the solar energy in a large number, one needs a personal room for the batteries. It pollutes the environment chemically.
1. Solar energy is the energy that we get from the sun. ________
2. Solar energy is renewable and pollution-free energy. ________
3. Solar energy will end one day. ________
4. Maintaining a solar power plant requires a lot of manpower ________
5. One can get a non-stop power supply even in the rainy season with the help of solar panel_______
6. One of the disadvantages of using solar energy is the very high initial setup cost. ________
5. Read the following passage, and then tick the correct answers: true (T), or false (F).
“ My name is Professor Roberts, and tonight, I’m going to tell you how to save energy in your homes. Most of us use too much energy. You can reduce this amount by: using low energy light bulbs, using solar energy, turning off unnecessary lights, preparing food before turning on the cooker. If you follow these simple rules, you will not only save energy but also keep the environment cleaner.”
1. The professor tells us about the ways to cut down on wastes of energy in our offices.
2. Almost everyone consumes too much energy.
3. Although solar energy is clean, the lecturer doesn’t advise us to use it.
4. The speaker gives four simple rules.
5. According to the speaker, energy will be saved.
