IX. Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. Energy is the power we use for transportation, for heat and light in our homes and for the manufacture of all kinds of products. There are two sources of energy: renewable and non-renewable energy. Most of the energy we use comes from fossil fuels which are non-renewable energy sources , such as oil, coal, natural gas and petroleum. These kinds of energy are harmful because they release a great amount of carbon dioxide into our environment. It is considered as a cause of global warming and rapid climate change. Renewable sources of energy can be used over and over again. Renewable resources include solar energy, wind, geothermal energy, biomass and hydropower. Solar energy comes from the sun. Some people use solar panels on their homes to convert sunlight into electricity. Wind turbines, which look like giant windmills, generate electricity. Geothermal energy comes from the Earths crust. Engineers extract steam or very hot water from the Earths crust and use the steam to generate electricity. Biomass includes natural products such as wood, manure and corn. These materials are burned and used for heat. Dams and rivers generate hydropower. When water flows through a dam it actives a turbine, which runs an electric generator. Câu 28. What do we use energy for? A. transportation, heat, light B. manufacture, transportation, heat and light C. generating hydropower and sunlight D. burning the materials such as wood, manure and corn.
