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

4. What is the height of the largest wind turbines?

A. as tall as a 20 story building B. between 8 and 25 feet

C. 30 feet D. 50 feet

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

Read the passage and write T (True) or F (False) next to the sentences.

Solar energy

Solar energy is the energy that we get from the sun and converted into thermal or electrical energy. Solar energy is a renewable energy because it will never end as long as the sun remains. Solar energy is also pollution-free because there will be no pollution occurring while producing solar energy. Solar energy is not only pollution-free energy but also its maintenance cost is very low, so to maintain a solar power plant, less manpower is required than others. Also, one can get a non-stop power supply even in the rainy season with the help of solar panels. However, there are also some disadvantages of using solar energy like the initial setup cost of panels and battery is very high. To store the solar energy in a large number, one needs a personal room for the batteries. It pollutes the environment chemically.

1.Solar energy is the energy that we get from the sun. ________

2.Solar energy is renewable and pollution-free energy. ________

3.Solar energy will end one day. ________

4.Maintaining a solar power plant requires a lot of manpower ________

5.One can get a non-stop power supply even in the rainy season with the help of solar panels. ________

6.One of the disadvantages of using solar energy is the very high initial setup cost. ________
