阅读理解。阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
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 fi
rst 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.
风能早在公元前七世纪就开始被人们用风车所利用，当人们发明了电以后，风能被用来发电，但随着电的广泛使用，风车逐渐不被人们使用了。而进入二十世纪七十年代后，人们又逐渐认识到了风能的优势。
1．From the text we know that windmills ________.
A. were invented by European armies
B. have a history of more than 2,800 years
C. used to supply power to radio in remote areas
D. have rarely been used since electricity was discovered
答案：C。细节理解题。由第一段最后两句话可知风车首先是在古代伊朗被使用，故排除A项；公元前七世纪到现在应是不足2800年，故排除B项；由第二段当中的第二、三句话可以排除D项，同时也能知道C项是正确的。
