1、Sleeping GiantRight now, an eruption is brewing in Yellowstone National Park. Sometime during the next two hours, the park\'s most famous geyser, Old Faithful, will begin gurgling boiling water and steam. Then, an enormous fountain will shoot high into the air .Old Faithful is not only a spectacular sight; it\'s also a constant reminder that Yellowstone sits on one of the largest volcanoes in the world. If you\'ve never heard of Yellowstone\'s volcano, you\'re not alone. The volcano is so inconspicuous(不显眼的) that few people know it exists. Yet it has erupted three times during the last 2 million years. And one of those eruptions spewed enough volcanic ash and other debris to blanket half the United States.Yellowstone\'s volcano is sometimes called a "super volcano," or extremely large and explosive caldera volcano. Three calderas make up more than a third of Yellowstone National Park. This super volcano formed over a hot spot, an extremely hot area in Earth\'s mantle. John Valley, volcano professor, said that as the crust moves across a hot spot, the hot spot melts a. section of the plate moving over it, forming "one volcano after another. "The Yellowstone hot spot melts thick continental crust, which may cause catastrophic eruptions. According to experts the eruptions that created each of the three calderas in and around Yellowstone National Park were larger than any other volcanic eruption in recorded history. The most recent eruption, which happened 640,000 years ago, produced at least l,000 cubic kilometers of ash and debris, which blanketed most of the western half of the United States. The first Yellowstone eruption, 2 million years ago, released more than double that amount of ash and debris.Geological evidence shows Yellowstone has blown its stack every 700,000 years or so. "If nature were truly that regular and reliable, we would be clue for another eruption soon," said Valley. "However, these processes are subject to variability, so we don\'t really know when the next eruption will happen. "_____. It is the volcanic energy that powers the geysers and hot springs, creates the mountains and canyons, and generates the unique ecosystems that support Yellowstone\'s diverse wildlife.【单选题】

正确答案:E

答案解析:第50题所在段的前面两段介绍了黄石公园火山以前喷发时的可怕情景。第50题所在段也叙述了火山能量带来的好处。这是两种情景截然相反的描写，中间很可能有一句过渡句，把它们连接起来。选项E就是过渡句，应该是本题的答案。

2、Gun Rights in the USImmediately 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】

A.some

B.few

C.much

D.little

正确答案:B

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。

3、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 _____ 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 every 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.above

B.below

C.within

D.beyond

正确答案:A

答案解析:本段前面的句子说到最低温度不会低于-273℃，所以below、within、beyond都有悖于上述论述。只有above（高于）才与上文的意思相符。

4、Mary rarely speaks to Susan.【单选题】

A.slowly

B.seldom

C.weakly

D.constantly

正确答案:B

答案解析:玛丽很少和苏珊说话。本题难度不大，干扰项干扰不强。rarely和seldom都可指“很少地”，其他项和答案意义差异较大，最佳答案是B。

5、Operatunity1. Operatunity is a TV talent show for amateur opera singers, The winners get the chance to sing with the English National Opera. When two housewives, Denise Leigh and Jane Gilchrist won in 2002, their lives changed forever, As they sang Verdi\'s Rigoletto at the Coliseum (音乐厅) in Rome, they were transformed from working mothers into opera celebrities (名人).2. "I live in the village I was born in," says Denise, who is blind. "Lots of my neighbours are family, and my life is all about my three children. Jane, who worked as a cleaner and a shop assistant, was in a similar situation." She says. All I had to look forward to was seeing my four children grow up, and I love them, but ... you know there must be more things than life. Winning Operatunity has opened up avenues I never knew existed."3. "Last year was amazing," Denise continues, "Last month was Paris, before that we were recording at Abbey Road, in London, and recently we had our album launch at the Royal Opera House" "We\'ve been treated like princesses," laughs Jane, "... champagne, chocolates, five - star hotels ..."4. But it wasn\'t all so easy. For Denise, the worst part was waiting at the beginning. "After I\'d sent in my application form I worried for a month, Then I had to wait ten days after my first audition (试唱). That was awful." Even when they won the competition they were allowed to tell their close family but they weren\'t allowed to tell anyone else until later. Denise and Jane also found the travelling is difficult. They couldn’t take their children with them while they were away singing, so they had to organise childcare. However, there\'s been no problem with the physical side of singing: "We didn\'t have to worry about that as we\'ve had lots of help and wonderful voice training." says Jane. They also had to learn to deal with the media." The kids loved the fact that they could stay up and watch us on TV, but I just couldn\'t understand why some newspapers were more interested in the fact I divorced at 21, rather than the fact I had just sung at the Coliseum, says Denise.Being celebrities, Denise and Jane had to learn to ____.【单选题】

A.help others out

B.take care of their children
