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。
