（2011·安徽卷）B

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。

　　One of every 10,000 Americans will be murdered this year. More Americans were murdered from 1970 through 1974 than were killed in Vietnam (越南). Since 1990, more than 800,000 American civilians (平民) have been killed by gunfire—more than the total number of casualties (伤亡) in U.S. wars from the Revolution to Indochina.

　　Two-thirds of all murders in the United States are committed (犯罪) with guns, 92 percent of them handguns. Murder rates are highest in these parts of America with the largest percentage of gun owners, lowest in those with the smallest. Since 1968, the murder rate in the United States has more than doubled.

　　These statistics (统计数字) were culled (拣选) from Dr. Donald T. Lunder's recent monograph (专论), Murder and Madness (available) from the Stamford, Calif.. Much of what he reports has been noted before by others, but rarely if ever has anyone probed so comprehensively (综合性地) the American way of killing.

　　As a psychiatrist (精神病学家) who has worked in the police-court-prison system, Lunder notes that the average murderer today is only 20 years old, that 94 percent of all murders are intra-racial, that when they are not, blacks are more often the victims (受害人) of whites, that less than 30 percent of murder victims are strangers to their killers, that the South has the highest murder rate (3.6 per 100,000 that same year), that most murders are committed with little or no planning, that most murderers are easily apprehended (逮捕) and readily confess. (承认)

　　In the majority of homicides (杀人者) the killers had been drinking before hand. Since most homicides arise in the context of a quarrel and involve the most readily available weapon, it is worth surmising (猜测) what would happen if guns were not readily available. Knives—now the second most common weapon-would presumably (大概) become the most likely weapon in the typical assault (袭击) between spouses, lovers, neighbors, etc. In fact the death rate for all victims assaulted with guns is as much as five times that of those assaulted with knives.

3．In most cases, the murder happened in the context of ________.

[　　]

A．mind illness

B．a intra-racial conflict

C．a quarrel between strangers

D．a quarrel with a weapon at hand

4．Which is the discovery of Dr. Lunder?

[　　]

A．The murder rate in the United States has risen.

B．The murder rates are highest in those parts of America where the owning percent age of guns are highest.

C．Besides guns, knives are the most common weapons for murders.

D．It's not very difficult to catch a murderer and have him tell the truth.

5．What can we infer from the passage?

[　　]

A．A lot of Americans died in the Wars in Indochina.

B．If the possession of guns are controlled, the murder rate will fall down.

C．As a psychiatrist, Dr. Lunder can do much to help those murderers to confess their guilt.

D．Without guns at hand, no murders will happen in a family.
