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.
C. Grinding wheat into flour.
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。
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.

第一节:阅读理解(共15小题;每小题2分,满分30分)
阅读下面短文,掌握其大意,然后从41—55各题所给的四个选项(A、B、C、D)中,选出最佳选项,并在答题卡上将该项涂黑。
(A)
We're all connected. You can send an e-mail message to a friend, and your friend can pass it on to one of his or her friends, and that friend can do the same, continuing the chain. Eventually, your message could reach just about anyone in the world, and it might take only five to seven e-mails for the message to get there.
Scientists recently tested that idea in a study involving 24,000 people. Participants had to try to get a message forwarded to one of 18 randomly chosen people. Each participant started by sending one e-mail to someone they knew. Recipients could then forward the e-mail once to someone they knew, and so on.
Targets, who were randomly assigned by researchers from Columbia University in New York, lived in 13 countries. They included an Australian police officer, a Norwegian veterinarian, and a college professor.
Out of 24,000 chains, only 384 reached their goal. The rest petered out, usually because one of the recipients was either too busy to forward the message or thought it was junk mail.
The links that reached their goal made it in an average of 4.05 e-mails. Based on the lengths of the failed chains, the researchers estimated that two strangers could generally make contact in five to seven e-mails.
The most successful chains relied on casual acquaintances rather than close friends. That's because your close friends know each other whereas your acquaintances tend to know people you don't know. The phenomenon, known as the strength of weak ties, explains why people tend to get jobs through people they know casually but aren't that close to.
So, start networking and instant messaging now. As they say in show business: It's all about who you know.
41. If you want to get into touch with a stranger in the world, how many e-mails might it take for the message to reach him/her?
| A. 5 to 7 | B. 18 | C. 13 | D. 384 |
| A. 24,000 people took part in the study and sent e-mails to people they knew. |
| B. The 18 targets were chosen by chance. |
| C. About 98.4% of the mails didn’t reach their goal because some people were too busy or they mistook the message for junk mail. |
| D. The targets come from 13 countries, such as Australia, Norway and New York. |
| A. make sure | B. suppose | C. think over | D. imagine |
| A. Because close friends don’t talk with each other so much. |
| B. Because casual acquaintances can help you know more people and make more friends. |
| C. Because close friends don’t spend so much time gathering together. |
| D. Because casual acquaintances are kinder and more willing to help others. |
