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 unevenly B. wind flow
C. motion energy D. wind turbines
2.Which of the following is NOT mentioned as a factor affecting the wind direction?
A. earth’s terrain B. bodies of water
C. vegetative cover D. the Sun
3.The word “variety” is closest in meaning with_________.
A. capacity B. popularity C. diversity D. minority

5. A small home-sized wind machine can produce enough power for_________ .
A. 20 buildings B. a small business
C. 400 homes D. a football field
6. How much power do single small turbines generate?
A. about 30 kilowatts B. more than 50 kilowatts
C. about 750 kilowatts D. less than 50 kilowatts
