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.
1. What does the passage primarily discuss?
A. Advantages and disadvantages of solar energy.
B. Solar energy's advantages over other sources of energy.
C. The cost of solar energy.
D. Solar energy as an alternative for fossil fuels.
2. What does the word “they” in line 3 refer to?
A. solar energy users. B. other renewable resources. C. advantages. D. solar cells.
3. Which of the following is the main disadvantage of solar energy mentioned in the passage?

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 coal, oil and gas on 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 temperature 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 of power. Another source of energy from nature is the wind which is clean and plentiful. Energy from the wind has been used for centuries to move ships, grind grain, pump water and do other forms of work. In recent time, wind has been used to generate electricity. Water can also provide power. For a long time, people have used water to power machines. Some early uses of water were to mill grain, saw wood and power machinery for the textile industry. Today water is mostly used to generate electricity. 28. The fossil fuels on earth are ....................... A. unlimited B. being used up C. renewable D. not uesd now 29. Solar energy means the power from the ............................. A. fossil fuel B. temperature C. electricity D. sun 30.
