 SKILLS
 DO YOU KNOW?
 RENEWABLE ENERGY
 Renewable energy is often called green energy because it is natural, available and does not have 
 to be formed like non-renewable energy. The green energy is always there. For example, the Sun 
 consistently shines, water is abundant, and the winds blow throughout the year. The five types 
 include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, 
 energy from moving water; biomass, energy from dead plants and finally, energy from the wind.
 KỸ NĂNG ĐỌC (READING SKILLS)
 I - Read the passage and choose the best option to answer each of the following questions.
 Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun. Wind 
 flow patterns are changed by the earth’s terrain, bodies of water, and vegetative cover. This wind flow, or 
 motion energy, when “harvested” by modern wind turbines, can be used to generate electricity.
 Wind turbines are available in a variety of sizes, and therefore power ratings. The largest machine has blades 
 that span more than the length of a football field, stands 20 building stories high, and produces enough 
 electricity to power 1,400 homes. A small home-sized wind machine has rotors between 8 and 25 feet in 
 diameter and stands upwards of 30 feet, and can supply the power needs of an all-electric home or small 
 business, utilityscale turbines range in size from 50 to 750 kilowatts. Single small turbines, below 50 kilowatts, 
 are used for homes, telecommunications dishes, or water pumping.
 1. What is the reason for the existence of wind?
 A. atmosphere heated unevenlyB. wind flow
 C. motion energyD. wind turbines
 2.Which of the following is NOT mentioned as a factor affecting the wind direction?
 A. earth’s terrainB. bodies of water
 C. vegetative coverD. the Sun
 3.The word “variety” is closest in meaning with_________.
 A. capacityB. popularityC. diversityD. minority
 4.What is the height of the largest wind turbines? 5. By 2013, people use about 80 percent of fossil fuels in the world.
 6. One day, when people use up all fossil fuels, they will die because 
 there is no alternative energy.
 7. Renewable energy will be used up one day.
 8. Solar energy and wind energy are two types of alternative energy.
