America’s greatest technological achievement, the Hoover Dam, now has a companion piece, a bridge held up by the longest arch in the Western Hemisphere（半球）. The Mike O’Callaghan-Pat Tillman Memorial Bridge, which opened this month and connects the U.S. states of Arizona and Nevada, crosses the vast chasm（峡谷）890 feet above the Colorado River that is controlled by the dam.
The striking 1,900-foot-long structure will improve traffic in the region and help protect the dam from being destroyed. It is the seventh highest bridge in the world, behind four in China, one in Papua New Guinea and one in the US state of Colorado.
“The Hoover Dam is the greatest civil engineering achievement in America’s history,” said the bridge project manager Dave Zanatell. “Our goal was not to outdo or outshine it. Our goal was to, in a respectful way, do something that would be great for our generation and that would stand besides Hoover Dam in a respectful and quality way that would become a part of Hoover’s legacy（遗产）.”
Just as the Hoover Dam was built in the heart of the Great Depression（大萧条）and was seen as an example of the nation’s can-do spirit, some hope this project can also provide some uplift.
The bridge is surprising: at 1,050 feet, its support arch holds up a roadway that lies on 300-foot-long concrete pillars（柱子）, some of the tallest in the world. It contains 16 million pounds of steel.
　　The idea of the bridge came into being in the 1960s because the top of the Hoover Dam has been a narrow two-lane road that is the fastest route from Arizona to Las Vegas and then the Pacific Northwest and Canada.
　Access to the dam from each direction is a dangerously winding route, but massive trucks and passenger vehicles shared it for decades. During the day, when thousands of tourists travel to the dam from Las Vegas three times as many accidents as on a normal road will happen.
　The bridge has a sidewalk on the side facing the dam. The wall on both sides is 54 inches high, so walkers can take photos there.
【小题1】Which of the following is true of the Hoover Dam?

　　In the United States in the early 1800’s, individual state governments had more effect on the economy than did the federal government. States controlled manufacturing, banking, mining and transportation firms and participated in the construction of various internal improvements such as canals, turnpikes（收费关卡）, and railroads. The states encouraged internal improvements in two distinct ways: first, by actually establishing state companies to build such improvements; second, by providing part of the capital for mixed public-private companies setting out to make a profit.
　　In the early nineteenth century, state governments also engaged in a surprisingly large amount of direct restricting activity, including extensive licensing and inspection programs. Licensing targets reflected both similarities in and difference between the economy of the nineteenth century and that of today: in the nineteenth century, state regulation through licensing fell especially on drug dealers, innkeepers and retail merchants of various kinds. The goods of trade generally came under state inspection and such important raw material as lumber and gunpowder were also subject to state control. Finally, state governments experimented with direct labor and business regulation designed to help the individual laborer or consumer, including setting maximum limits on hours of work and restrictions on price-fixing by business.
　　Although the states dominated economic activity during this period, the federal government was not inactive. Its goals were the facilitation of western settlement and the development of native industries. Toward these ends the federal government pursued several courses of action. It established a national bank to stabilize banking activities in the country and, in part, to provide a supply of relatively easy money to the region, where it was greatly needed for settlement. It permitted access to public western lands on increasing easy term, with a summit in the Homestead Act of 1862, by which title to land could be claimed on the basis of residence alone. Finally, it set up a system of tariffs（关税） that was basically protectionist in effect, although maneuvering for position by various regional interests produced frequent changes in tariff rates throughout the nineteenth century.

　　A. States rights versus federal rights.
　　B. The participation of state governments in railroad, canal, and turnpike construction.

3.According to the passage, which of the following is true of the Homestead Act of 1862？
　　A. It increased the money supply in the West.
　　B. It was a law first passed by state government in the West.
　　C. It made it increasingly possible for settlers to obtain land in the West.
　　D. It established tariffs in a number of regions.
4.Which of the following activities was the responsibility of the federal government in the nineteenth century？
　　A. Control of the manufacture of gunpowder.
　　B. Determining the conditions under which individuals worked.
　　C. Regulation of the supply of money.
　　D. Inspection of new homes built on western lands.

　　BBC(May 11,2008) - Edinburgh Zoo makes plans to bring a pair of giant pandas from China to Scotland.Zoo representatives recently returned from China,where they signed a letter of intent(意向书) making a promise to bring giant pandas to Edinburgh.
　　It's been suggested that a breeding pair should be on loan(暂借) to the Royal Zoological Society of Scotland(RZSS) for 10 years.It is hoped that they would give birth to cubs during that time.Edinburgh Zoo would be only the eighth Zoo in the Western hemisphere(半球) to care for the species if the project goes ahead.
　　Zoo chiefs said that looking after the endangered animals could benefit conservation.David Windmill,chief executive of RZSS,said,"Working with giant pandas means so much more to us than introducing a new species to our collection.It's an opportunity to work on a global level with other conservationists to gain a better understanding of giant pandas,the threats they face,and what we can do to ensure their survival."
　　At present there're only around 1,500 giant pandas in the wild.RZSS has been working on the project for almost a year,and hopes to have giant pandas at Edinburgh Zoo by 2009 ,the year of the society's centenary(一百周年纪念日).
　　Mr.Windmil said that the project had received strong support from the UK and the Scottish government and that this must continue if the zoo was to reach an agreement with the Chinese.As part of the proposed agreement with the Chinese government,Edinburgh Zoo will collaborate(合作) on research projects benefiting conservation in the wild.
　　RZSS will also provide considerable money to support giant panda conservation projects in the wild.Giant pandas live in a few mountain ranges in central China and feed almost only on bamboo,which makes up 99% of their diet.
　　68.What is the best title for the passage?
　　　A.Edingburgh Zoo does research into giant pandas.
　　　B.Giant pandas live happy at Edinburgh Zoo.
　　　C.Edinburgh Zoo expects giant pandas from China.
　　　D.Scotland supports giant panda conservation.
　　69.If Edingburgh Zoo can borrow giant pandas,what will happen?
　　　A.RZSS will have a better understanding of living habits of giant pandas.
　　　B.RZSS will celebrate its centenary in 2009.
　　　C.Scotland will be the eighth country to have giant pandas.
　　　D.Edinburgh Zoo will be the eighth zoo to have giant pandas in the world.
　　70.At present what seems to be the key factor for giant pandas to successfully go to Edinburgh Zoo?
　　　A.RZSS's attitude.
　　　B.The Scottish government's attitude.
　　　C.Edinburgh Zoo's support.
　　　D.The Chinese government's attitude.
