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.

【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。

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.

【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

【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。

Years ago while lying in my hammock （吊床）and drinking JD from the bottle, I noticed my dog dragging something under the fence．Upon inspection, to my disappointment, I realized it was the next door neighbor' s 10 - year - old daughter' s rabbit．For years I had watched her come home from school and head straight out to its cage, free it and play with it in the yard．I knew that day would be no different and fearing for our dog, I had to think fast．

The rabbit was quite dirty, as if it had put up quite a struggle, so I washed it, combed it with the dog brush and blew it dry with the leaf blower．Upon finishing its grooming I jumped the fence and replaced it back in its cage hoping its death would be written off as "natural caused"．

Back to the hammock and JD．Within the hour the neighbor' s Volvo palled in as usual and out popped the little girl, and as usual she headed straight for the cage．Only this time she stopped about six feet away and screamed: " D - A - D - D – Y！！！"

Her father, panic stricken, stood looking at the cage．Being the good neighbor that I am, I rushed to fence and asked if there was anything I could do．
