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?

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。
查看习题详情和答案>>How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.
There are now more than a thousand genetic（基因的）tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.
“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.
“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”
Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.
71.The first paragraph is meant to__________.
A. ask some questions B. introduce the topic
C. satisfy readers’ curiosity D. describe an academic fact
【答案】B
【解析】通过两个问题引出话题。
72.Which of the following is true of James Watson？
A. He is strongly in favor of the present genetic tests.
B. He is more likely to suffer from Alzheimer’s disease.
C. He believes genetic mapping can help cure any disease.
D. He doesn’t want to know his chance of getting a disease.
【答案】D
【解析】根据第二段Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’。“James Watson要求如果他的基因表明他有很高的老年痴呆症的可能不要告诉他。”
73.According to Paragraphs 3 and 4, if a person is at a higher genetic risk, it is__________.
A. advisable not to let him know B. impossible to hide his disease
C. better to inform him immediately D. necessary to remove his anxiety
【答案】A
【解析】根据这两个自然段可知，如果你提前被告知你将来可能患某种可怕的疾病会mess you up。
74.The underlined part“freak out”in Paragraph 5 is closest in meaning to“_________”.
A. break down B. drop out C. leave off D. turn away
【答案】A
【解析】根据下文But的转折，以及no significant difference可知，freak out的意思是A（精神垮掉）。
75.The study led by Dr. Green indicates that people__________.
A. prefer to hear good news B. tend to find out the truth
C. can accept some bad news D. have the right to be informed
【答案】C
【解析】根据第五段内容 In fact, most people think they can handle it可知答案选C.
