1、Migrant (移民的) Workers
In the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some countries have restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, where increased oil incomes have enabled many countries to call in outsiders to improve local facilities. Thus the Middle East has attracted oil workers from the USA and Europe. It has brought in workers from many countries, including South Korea and Japan.
In view of the difficult living and working conditions in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and this is a major attraction .
Sometimes a disadvantage has a compensating (补偿的) advantage. For example, the difficult living conditions often lead to increased friendship when workers have to depend on each other for safety and comfort. In a similar way, many migrant workers can save large sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.
One major problem which ______ migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case, migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.

2、Sleeping Giant
Right 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. _____.
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. "
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.

3、Robotic Highway Cones
A University of Nebraska professor has developed robotic cones and barrels. These robotic cones and barrels can move out of the way, or into 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 professor of mechanical engineering at Nebraska.
For example, 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 for robots," Farritor said. "The robotic cones would also help remove people from hazardous jobs on the highway putting barrels and cones into place," Farritor said in a report on his creation.____ . The fund allowed Farritor to 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," Farritor said. "Normally there's a kind of rubbery, black base to them. We replace that with a robot. .
Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most useful to what they might need
The robots could come in handy following a slow-moving maintenance operation, like painting a stripe on a road or moving 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 for the operation. " Farritor said.
While prototypes have been made, they are not in use anywhere. Farritor said he has applied for a patent and is considering what to do next. He is thinking about starting a small business. . 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.Farritor was "Inventor of 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, or into place, from computer commands made miles away.

正确答案:D

答案解析:本段的第2句有The fund，fund之前用的是定冠词the，说明前面已有句子提到过fund或其他类似资助的词。D句说的是grant，所以D句是答案。

4、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 _____ 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 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.Earth

B.space

C.planet

D.star

正确答案:B

答案解析:纵观本段，内容是叙述宇宙空间的温度。选项B的space是“宇宙空间”的意思，所以是答案。其他三个选项Earth（地球）、planet（行星）、star（恒星）在词义上都不合适。

5、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."
