（2011·安徽卷）B

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 sources（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 the 1940s, 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 costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

60. 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

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

A. Sailing a boat. 

B. Producing electricity.

D. Pumping water from underground.

62. One of the reasons wind was rediscovered in the 1970s 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

63. 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.

【解析】选D。推理判断题。根据末段句子Today, there is a global movement to supply more and more of our electricity through the use of wind可知，接下来作者应该谈论利用风能发电的情况，因此选择D项。
