سؤال ۱۴، زبان انگلیسی ۳، شهریور ۱۴۰۴

متن زیر را بخوانید، سپس به سوالات مربوطه پاسخ دهید.One of the most essential issues which nations must consider these days is providing energy with their people. In the past, energy was produced from fossil fuels such as oil, coal, and natural gas. Although such fuels have been main resources for years, they are harmful to the environment. They have caused serious problems including air or water pollution, global warming and health problems. Also, they take millions of years to form, so they are nonrenewable- cannot be replaced easily.To reduce bad effects of nonrenewable energy, scientists are trying to replace it with other energy resources which are friendly to the environment. Such energy sources are called clean energy as they reduce the environmental risks and don’t cause serious problems for humans. They are made from resources that can be replaced like wind, water, sunshine, tides and plants. As a vast country that is rich in sun radiation during most time of the year, Iran can generate enough energy by setting solar panels in desert areas like Yazd, south of Semnan or Kashan. In short, it seems that replacing fossil fuels with solar energy is the main solution to the various problems caused by burning fossil fuels.
