九年级英语科普知识应用练习题30题
九年级英语科普知识应用练习题30题1<背景文章>Solar energy is one of the most promising sources of renewable energy. It is harnessed from the sun's rays and converted into useful forms of energy. The principle behind solar energy is relatively simple. Photovoltaic cells, also known as solar cells, are made of materials that can absorb sunlight and convert it into electricity.The advantages of solar energy are numerous. Firstly, it is a clean and renewable source of energy, which means it does not produce any harmful emissions or pollutants. Secondly, it is abundant and freely available. As long as the sun shines, there is a constant supply of solar energy. Thirdly, solar energy systems can be installed in a variety of locations, from rooftops to remote areas where there is no access to the electricity grid.Solar energy has a wide range of applications. It can be used to power homes, businesses, and even entire communities. Solar panels can be installed on rooftops to generate electricity for household use. In addition, solar energy can be used to heat water for domestic and industrial purposes. Solar-powered street lights are also becoming increasingly common in many cities.Solar energy is not without its challenges, however. One of the mainchallenges is the cost of installing solar energy systems. Although the cost has been declining in recent years, it can still be relatively expensive. Another challenge is the intermittent nature of solar energy. Since the sun does not shine all the time, there is a need for energy storage systems to ensure a continuous supply of electricity.Despite these challenges, solar energy is expected to play an increasingly important role in meeting the world's energy needs in the coming years. As technology continues to improve and costs continue to decline, more and more people are likely to turn to solar energy as a viable alternative to fossil fuels.1. What is the principle behind solar energy?A. It is generated by wind turbines.B. It is harnessed from the sun's rays and converted into electricity.C. It is produced by nuclear reactors.D. It is created by burning fossil fuels.答案：B。

九年级英语科普知识应用练习题20题
九年级英语科普知识应用练习题20题1<背景文章>Solar energy is one of the most promising sources of renewable energy. It is clean, abundant, and sustainable. The principle of solar energy is based on the conversion of sunlight into electricity or heat.Solar panels are made up of photovoltaic cells that absorb sunlight and convert it into direct current (DC) electricity. This electricity can then be used to power homes, businesses, and even entire communities. In addition to generating electricity, solar energy can also be used for heating and cooling. Solar water heaters, for example, use the sun's energy to heat water for domestic use.The applications of solar energy are widespread. In remote areas where there is no access to the electrical grid, solar power is often the only source of electricity. Solar-powered street lights, traffic signals, and communication towers are also becoming increasingly common. In addition, many countries are investing in large-scale solar power plants to meet their growing energy needs.The future of solar energy looks bright. As technology continues to improve, the efficiency and cost-effectiveness of solar panels are expected to increase. This will make solar energy even more competitive withtraditional sources of energy such as coal, oil, and natural gas. In addition, new applications for solar energy are being developed all the time, such as solar-powered cars and airplanes.In conclusion, solar energy is a powerful and versatile source of renewable energy that has the potential to transform the way we live and work. With its many benefits and growing popularity, it is likely that solar energy will play an increasingly important role in our future.1. What is the principle of solar energy based on?A. The conversion of wind into electricity.B. The conversion of sunlight into electricity or heat.C. The conversion of water into steam.D. The conversion of coal into gas.答案：B。
