     Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat.

Wind is one of our cleanest and richest power source (来源), as well as one of the oldest. Evidence shows

that windmills (风车) began to be used in ancient Iran back in the seventh century BC. They were first

introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of

using wind power.

     For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep

underground. When electricity was discovered in the late 1800s, people living in remote areas began to use

them to produce electricity. This allowed them to have electric lights and radio. However, by the1940s

when electricity was available to people in almost all areas of the United States, windmills were rarely used.

    During the 1970s, people started becoming concerned about the pollution that is created when coal and

gas are burned to produce electricity. People also realized that the supply of coal and gas would not last

forever. Then, wind was rediscovered, though it means higher coasts. Today, there is a global movement

to supply more and more of our electricity through the use of wind.

1. From the text we know that windmills _____.

A. were invented by European armies

B. have a history of more than 2800 years

C. used to supply power to radio in remote areas

D. have rarely been used since electricity was discovered

2. What was a new use for wind power in the late l9th century?

A. Sailing a boat.

B. Producing electricity.

C. Grinding wheat into flour.

D. Pumping water from underground.

3. One of the reasons wind was rediscovered in the 1970 is that _____.

A. wind power is cleaner

B. it is one of the oldest power sources

C. it was cheaper to create energy from wind

D. the supply of coal and gas failed to meet needs

4. What would the author probably discuss in the paragraph that follows?

A. The advantage of wind power.

B. The design of wind power plants.

C. The worldwide movement to save energy.

D. The global trend towards producing power from wind.
