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.

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

A. wind power is cleaner

B. it is one of the oldest power sources

C. it was cheaper to create energy from wind

63. What would the author probably discuss in the paragraph that follows?

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。

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.

A. ask some questions                        B. introduce the topic

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。

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)。

That year , in the local school, there was a new math teacher, as well as some new pupils. One of the new kids was the stupidest child anyone had ever seen. It made no difference how quickly or how slowly they tried explaining numbers to him; he would always end up saying something enormously stupid. Like two plus two was five, seven times three was twenty-seven, or a triangle had thirty corners……
Before this boy arrived, math lessons had been the most boring of all. Now they were great fun. Encouraged by the new teacher, the children would listen to the pieces of nonsense spouted by the new kid, and they would have to correct his mistakes.
Whenever the new teacher asked questions, the stupid kid would stand up but made the wrong answers, the other students all wanted to be the first to find his mistakes, and then think up the most original ways to explain them. To do this they used all kinds of stuff : sweets, playing cards, oranges, paper planes, etc. It didn’t seem like any of this bothered the new kid.
However, Little Lewis was sure that it was bound to make him feel sad inside. Lewis was sure he would see him crying. So, one day, he decided to follow the new kid home after school. On leaving school, the new kid walked a few minutes to a local park, and there he waited for a while, until someone came along to meet him……
It was the new teacher!
The teacher gave the new kid a hug, and off they went, hand in hand. Following from a distance, Lewis could hear they were talking about math.
