1、Wealth
Among the more colorful characters of Leadville's golden age were H. AW. Tabor and his second wife, Elizabeth McCourt, better known as "Baby Doe". Their history is fast becoming one of the legends of the Old West. Horace Austin school teacher in Vermont. With his first wife and two children he left Vermont by covered wagon in 1855 to homestead in Kansas. Perhaps he did not find farming to his liking, or perhaps he was lured by rumors of fortunes to be made in Colorado mines. At any rate, a few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. "Great deposits of lead are sure to be found here. " he said.
As it turned out, it was silver, not lead, that was to make Leadville's fortune and wealth. Tabor knew little about mining himself, so he opened a general store, which sold everything from boots to salt, flour, and tobacco. It was his custom to "grubstake" prospective miners, in other words, to supply them with food and supplies, or "grub", while they looked for ore, in return for which he would get a share in the mine if one was discovered. He did this for a number of years, but no one that he aided ever found anything of value.
Finally one day in the year 1878, so the story goes, two miners came in and asked for "grub". Tabor had decided to quit supplying it because he had lost too much money that way. These were persistent, however, and Tabor was too busy to argue with them. "Oh help yourself. One more time won't make any difference," He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in gave Tabor a one-third interest in their findings. They picked a barren place on the mountainside and began to dig, After nine days they struck a rich vein of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the "Pittsburgh Mine," made l,300,000 for Tabor in return for his $17 investment.
Later Tabor bought the Matchless Mine on another barren hillside just outside the town for$117,000. This turned out to be even more fabulous than the Pittsburgh, yielding $35,000 worth of silver per day at one time. Leadville grew. Tabor became its first mayor, and later became lieutenant governor of the state.

3、Gun Rights in the US
Immediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president and the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.
Strictly speaking, the US is not the only country here gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the ____ countries that seem unwilling and politically incapable of doing anything serious to stop it.
In countries like Britain and Canada, the government adopted strict gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) and the electoral (选举) system.
The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign for gun control or win power, not both, they prefer power.
According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don't want to give up their arms they keep to protect themselves.
Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professor in the Virginia incident had been carrying a legal weapon, they might have been able to stop all this. "In his opinion, the massacre (大屠杀) is an argument for more people to carry weapons, not fewer.
Americans' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK's Guardian newspaper.
One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American's responsibility to have a gun.
"Each person," he said, "should not rely solely on the government for protection."
【单选题】

答案解析:本题难度较大，干扰项干扰较强，考点是few的用法。文章此处是说“美国是少数几个不愿意禁止枪支暴力的国家之一”，要选取“少数”的意思，最佳答案是B。

4、Human Space Exploration
While scientists are searching the cause of the Columbia disaster, NASA is moving ahead with plans to develop a new craft that would replace shuttles(航天飞机) on space station missions by2012 and respond quickly to space station emergencies.
The space agency released the first set of mission needs and requirements several days ago for me orbital space plane (轨道航天飞机), which would be designed to transport a crew of four to and from the International Space Station.
Although it includes few specifics, the plan states the orbiter(轨道航天飞机) will be safer cheaper and require less preparation time than the shuttle. It would be able to transport four crew members by 2012 though it would be available for rescue missions by 2010. NASA says the craft should be able to transport injured or ill space station crew members to "definitive(决定性的) medical care" within 24 hours.
The release of the requirements showed NASA remains focused on the long-term priorities of space exploration, even as questions exist concerning the loss of Columbia and its seven member crew on February l, 2003.
Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working for years on a successor to the shuttle. The project, known as the Space Launch Initiative (倡议), was divided last year into two parts----one focusing on a future launch vehicle, the other on a space station orbiter. The orbiter is expected to be ready sooner.
The program's managers say NASA officials have told them not to alter Space Launch Initiative in light of the Columbia disaster.
U. S. President George W. Bush asked Congress for about US$1 billion for Space Launch Initiative in 2004, funds that would be almost equally split between the Orbital Space Plane and Next Generation Launch Technology.
Besides its main mission, the orbiter would also be used as .【单选题】

A.a medical research center

B.a space station

C.a space ambulance

D.a passenger plane

正确答案:C

答案解析:此题与第41题相连，问除了运送航天员这一主要使命外，航天飞机还用来干什么？原文第1句也回答了这个问题，那就是把它作为太空急救车，故C为正确答案。

5、What Is the Coolest Gas in the Universe?
What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.
We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.
The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.
Why is the two scientists' work so important to science?
In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein's calculations helped him theorize would behave as Bose thought but only at very cold temperatures.
Scientists have also discovered that ultra-cold atoms can help them make the world's atomic clocks even more accurate. These clocks are so accurate today they would only lose one second _____ six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.
【单选题】

A.any

B.each

C.every

D.some

正确答案:C

答案解析:从句子“These clocks are so accurate today they would only lose one second six million”推断，原子钟如此精确，每隔600万年才慢1秒。表示“每隔”的单词是every。
