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. _____. 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," ｏｒextremely 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 ｏｒso. "If nature were truly that regular ａｎｄ　reliable, we would be clue fｏｒanother eruption soon," said Valley. "However, these processes are subject to variability, so we don\'t really know when the next eruption will happen. "While the active geologist processes at Yellowstone do pose some risk to tire public, they also make it a unique treasure. 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】

2、How to Be a Successful Business personHave you ever wondered why some people are successful in business ａｎｄ　others are not? Here\'s a story about one successful business person. He started out washing dishes ａｎｄ　today he owns 168 restaurants.Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, ａｎｄ　when he was 16 years old, he learned to fly a small plane.At the age of 23 ａｎｄ　with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working fｏｒa company that rented cars.While Mr. Kazi was working at the car rental (租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. Fｏｒtwo months, he worked as a cook\'s assistant. His job was to clean the kitchen ａｎｄ　help the cook. "I didn\'t like it," Mr. Kazi says, "but I always did the best I could."One day, Mr. Kazi\'s two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.A few months later, the owners needed a manager fｏｒa new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager ａｎｄ　soon the restaurant was making a profit.A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside ａｎｄ　the food was terrible. Mr. Kazi borrowed money from a bank ａｎｄ　bought the restaurant.

3、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 few 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 majｏｒsupporter of gun rights in the US, is too strong fｏｒany party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign fｏｒgun control ｏｒwin power, not ____, they prefer power.According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted fｏｒnine 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 professｏｒin 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 fｏｒmore 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 fｏｒprotection."【单选题】

A.either

B.both

C.each

D.one

正确答案:B

答案解析:本题有一定难度，需要认真阅读文章，理解好句意。文章此处是说“要么为枪支控制发起活动，要么就是赢得总统大选，不可能两者都做到”，所以最佳答案是B。

4、Robotic Highway ConesA University of Nebraska professｏｒhas developed robotic cones ａｎｄ　barrels. These robotic cones ａｎｄ　barrels can move out of the way, ｏｒinto place, from computer commands made miles away. .They can even be programmed to move on their own at any particular part of the day, said Shane Farritor, an assistant professｏｒof mechanical engineering at Nebraska.Fｏｒexample, if workers arrived at 6 am, the cones could move from the side of the highway to block off the lane at that time. ａｎｄ　they can return to the original place at the end of the day. "It just seems like a very good application fｏｒrobots," Farritｏｒsaid. "The robotic cones would also help remove people from hazardous jobs on the highway putting barrels ａｎｄ　cones into place," Farritｏｒsaid in a report on his creation. Word on the idea began in 2002 using a National Academy of Sciences grant . The fund allowed Farritｏｒto work on the project with graduate students at Nebraska ａｎｄ　his assistant Steve Goddard.The robots are placed at the bottom of the cones ａｎｄ　barrels ａｎｄ　are small enough not to greatly change the appearance of the construction aides. "It would look exactly the same," Farritｏｒsaid. "Normally there\'s a kind of rubbery, black base to them. We replace that with a robot. .Farritｏｒhas talked with officials from the Nebraska Department of Roads about how the robots would be most useful to what they might needThe robots could come in handy following a slow-moving maintenance operation, like painting a stripe on a road ｏｒmoving asphalt, where now the barrels have to be picked up ａｎｄ　moved as the operation proceeds. "That way you don\'t have to block off a l0-mile strip fｏｒthe operation. " Farritｏｒsaid.While prototypes have been made, they are not in use anywhere. Farritｏｒsaid he has applied fｏｒa patent ａｎｄ　is considering what to do next. ____ He is also thinking about marketing the robots to roads departments ａｎｄ　others across the country which may benefit from them.【单选题】

A.ａｎｄ　they can return to the original place at the end of the day.

B.He is thinking about starting a small business.

C.Farritｏｒwas "Inventｏｒof the Year" in 2003.

D.Word on the idea began in 2002 using a National Academy of Sciences grant

E.We replace that with a robot.

F.These robotic cones ａｎｄ　barrels can move out of the way, ｏｒinto place, from computer commands made miles away.

正确答案:B

答案解析:本段的第4句“He is also thinking about. . . ”中的also是一个重要的线索，说明前面一定出现过“he is thinking”。但是在前面两句中没有找到，那么本段中要恢复的句子一定是 B句。

5、Stop Eating Too much"Clean your plate!"and" Be a member of the clean-plate club!" Just about every kid in the US has heard this from a parent ｏｒgrandparent. Often, it\'s accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa!" Sure, we should be grateful fｏｒevery bite of food. Unfortunately, many people in the US take too many bites. Instead of saying "clean the plate", perhaps we should save some food fｏｒtomorrow.According to news reports, US restaurants are partly to blame fｏｒthe growing bellies(肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value ａｎｄ　most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition (营养) professｏｒat Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline(腰围) began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling fｏｒthis too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can\'t afford fine dining still prefer large portions. Seventy percent of those earn at least $ 150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25, 000 want smaller.It\'s not that working class Americans don\'t want to eat healthy. It\'s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paycheck, happy to save a little money fｏｒnext year\'s Christmas presents.(2008年)Parents in the United States tend to ask their children ______.【单选题】

A.to save food fｏｒtomorrow

B.to wash the dishes

C.mottos eat too much

D.not to waste food

正确答案:D

答案解析:题干问“美国父母总是让他们的孩子做什么”。参见第一段，其中提到：每个美国孩子都能从父母或爷爷奶奶那里听到这样的话，“把你盘子里的东西吃光”。故正确答案为D。
