Aluminum is lightweight, rustproof and easily shaped into different forms. By mixing it with other metals, scientist have been able to produce a variety of alloys, some of which have the strength of steel but weigh only one third as much.
Today, the uses of aluminum are innumerable. Perhaps its most important use is in transportation. Aluminum is found in the engines of automobiles, in the hulls of boats. It is also used in many parts of airplanes. In fact, the huge "airbus" planes would probably never have been produced if aluminum did not exist. By making vehicles lighter in weight aluminum has greatly reduced the amount of fuel needed to move them. Aluminum is also being used extensively in the building industry in some countries.
Since aluminum is such a versatile(多用的) metal, it is fortunate that bauxite(铝土矿) , which is one of its chief sources, is also one of the earth's most plentiful substances. As the source of aluminum is almost inexhaustible, we can expect that more and more uses will be found for this versatile metal.
The price of aluminum was sharply reduced when people discovered a new refining process with the aid of______.
A.wind power
B.solar energy
C.hydraulic power
D.electricity

But complaints have steadily grown about a law that came with the spending bill. The Real ID Act of 2005 established national standards for driving licences. By 2008, it said, every state would have to make sure its licences included "physical security features" and "a common machine readable technology". A state would be responsible for verifying that anyone applying for licences is in America legally. Only licences that met the new standards would be accepted by the federal government. An American who wanted to fly commercially, or do anything else for which he needed to identify himself, would end up in a queue at the Department of Motor Vehicles.
The idea was to make life harder for would-be terrorists. But the scheme will certainly make life harder for the states. The Department of Homeland Security (DHS) reckons that implementing the changes will cost states up to $14.6 billion, with individuals on the line for an additional $8.@5 billion. And the federal government plans to meet only a fraction of the cost.
Critics also argue that the new licences will amount to national identification cards and will contain ton much information about the bearer. Immigration advocates say that the Real ID Act unfairly targets illegal immigrants. And from a security standpoint the act raises as many fears as it allays. Licences that meet the revised standards would be rich of sensitive data. They might prove irresistibly tempting to identity thieves and marketing firms.
On January 25th Maine became the first state to oppose the Act. Its legislature passed a resolution refusing to implement the Real ID Act with nearly unanimous support. On March 8th, Idaho approved a similar bill. Two dozen other states have measures pending that question the act or oppose it outright.
On March 1st the DHS issued guidelines for implementing the Real ID Act that manage to ignore most of these objections. The guidelines allow states a bit more time to implement the act. But they give no quarter on the expensive physical security features and suggest that states deal with privacy concerns on their own. And as the National Governors Association promptly noted, they "do nothing" to address the cost to states.
Which of the following consequence might be caused by the 2005 emergency spending bill?
A.financial support to the construction of international aid groups.
B.an act that has brought to great disputes among different states.
C.prohibitions of US citizens to take commercial flights.
D.against humanitarian aid to countries that were attacked by the Asian tsunami.
The best way to explain how this procedure is expected to work is to explain how it actually worked when it was first tried. The first experiment with it was the creation of the Works Project Administration (WPA). This agency set up work projects in various fields in which there were many unemployed. For example, unemployed actors were organized into theater projects, orchestras were organized for unemployed musicians, teaching projects for unemployed teachers, and even writers' projects for unemployed writers. Unemployed laborers were put to work building or maintaining roads, parks, playgrounds, or public buildings. These were all temporary "work relief" projects rather than permanent work opportunities.
More substantial work projects of a permanent nature were organized by another agency, the Public Works Administration (PWA). This agency undertook the planning of construction of schools, houses, post offices, dams, and other public structures. It entered into contracts with private construction firms to erect them, or it loaned money to local or state governments which undertook their construction. This created many jobs in the factories producing the material as well as in the projects themselves, and greatly reduced the number of unemployed.
Still another agency which provided work projects for the unemployed was the Civilian Conservation Corps (CCC). This agency provided job opportunities for youths aged 16 to 20 to work in national parks or forests clearing land, guarding against fires, building roads, or doing other conservation work. In the event of a future depression, the federal government might revive any or all of the above methods to relieve unemployment and stimulate business.
The PWA differed from the WPA in that the ______.
A.letters were reversed
B.work projects of the former were carded ont by the Federal government
C.government subsidized private industry
D.number of unemployed was reduced
The use of light for communication is one of the major directions that technology has taken ever since the middle of the nineteenth century. From still (静态的) photography to movies to television (with a development from black-and-white to color imagery in each) , photo technology has had a great effect upon mass communication and mass education. Unlike the printed word, visual images have more impact because they are more immediate; They copy reality in a way that the printed word cannot. Unlike letter shapes, they are not abstract; unlike words, they require no symbolic interpretation by the mind. Combined with the widespread and uniform. spreading of such images, phototechnology affects the thinking of vast audiences and shapes their view of reality.
As the number of commercially available television channels grows, the viewer's freedom of choice increases, but so does the burden of that choice.
It can be learned about the technology of light from the first paragraph that______.
A.its mere practical use is to enable people to see well
B.it achieved a remarkable development in the early nineteenth century
C.its development is related to the study of the history of technology
D.it has aroused the interest of inventors ever since ancient times

October 1929 was a month that had catastrophic economic reverberations worldwide. The American stock market witnessed the "Great Crash", as it is called, and the temporary boom in the American economy came to a standstill. Stock prices sank, and panic spread. The ensuing unemployment figure soared to 12 million by 1932.
Germany in the postwar years suffered from burdensome compensation it was obliged to pay to the Allies. The country's industrial capacity had been greatly diminished by the war. Inflation, political instability, and high unemployment were factors helpful to the growth of the initial Nazi party. Germans had lost confidence in their old leaders and heralded the arrival of a messiah-like figure who would lead them out of their economic wilderness. Hitler promised jobs and, once elected, kept his promise by providing employment in the party, in the newly expanded army, and in munitions factories.
Roosevelt was elected because he promised a "New Deal" to lift the United States out of the doldrums of the depression. Following the principles advocated by Keynes, a British economist, Roosevelt collected the spending capacities of the federal government to provide welfare, work, and agricultural aid to the millions of down-and-out Americans. Elected President for four terms because of his innovative policies, Roosevelt succeeded in dragging the nation out of the depression before the outbreak of World War II.
Continuing education gives these adults the opportunity to increase their knowledge about their own field or to learn about a new field. It also gives them a chance to improve their old skills or to learn new ones.
Continuing education classes give some adults the chance to learn new skills. There are usually many kinds of classes to choose from, foreign cooking, auto repair, or furniture repair. These are only some of the classes available.
Some adults take classes for fun or because the class will be useful for them. For example, they can choose a class in almost any language as a second language. There are classes in first aid or classes in sewing. There are also many other types of classes to choose from.
Other adults take continuing education classes to improve their own lives because they want to feel better about themselves. Overweight people can find exercise classes or classes in nutrition. Others can learn how to be good parents, or how to get along with other people.
There are many opportunities for adults to continue their learning. Almost any community college or public school system has a continuing education program. There are classes in schools, community buildings, or churches. Most classes are in the evening, so working people can attend. The classes are usually small, and they are inexpensive.
Thousands of people register for continuing education classes each year. They receive no diploma or certificate, and no grade for most of the classes they attend. For them, learning is something they do because they want to.
Some adults go to continuing education classes to ______.
A.get a college education
B.learn new skills
C.get a certificate
D.earn grades
