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(峽谷)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(遺產(chǎn)).”

Just as the Hoover Dam was built in the heart of the Great Depression(大蕭條)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.

Which of the following is true of the Hoover Dam?

   A. It was completed recently.

   B. It was built during the hard times.

   C. It has the longest arch.

   D. It’s the seventh highest dam in the world.

What is one of the purposes of building the bridge?

   A. To protect the dam.                                 B. To save the cultures.

   C. To outdo the dam.                                       D. To develop the tourism.

The underlined word “uplift” in Paragraph 4 means _____.

   A. lift of the heavy object                            B. support in money

   C. spiritual encouragement                           D. instruction in technology

Which of the followings shows the right position of the bridge and dam?

The text is mainly about ______.

   A. the Hoover Dam                                    

   B. American western development

   C. a tour along the Colorado River               

   D. a recently built bridge

  The idea of fighting a noise by making more noise sounds strange, but What's exactly that motor engineers are doing in Germany and some other countries.

  Carmakers' research and development laboratories have already proved that mixing in more noise with the help of loudspeakers can reduce the unwanted noise.

  Physicists have known about the technique for a long time.Sound is make up of pressure waves in the air.If two sound waves of the same frequency(頻率)mix so that the highest point of one wave happens at the same time with the lowest point of the other wave, the result is no sound.Therefore, by producing a perfect copy of the noise and delaying it by half a wave cycle(周期), we can kill the unwanted noise.Using this technique many carmakers are racing to develop noise-killing systems both inside and outside the cars.Another good thing about the use of noise-killing systems is that it saves the need for a silencer, which not only reduces the weight of a car, but also makes the motor bum less oil and work better.

  Some engineers believe that the noise-killing system will be used in most cars in 1996.But the carmakers haven't decided if they will put it into production because it would add several hundred dollars to the cost of their ears.

(1)

Which of the following gives a general idea of how the noise-killing system works?

[  ]

A.

By producing pressure waves going in the opposite direction.

B.

By mixing high frequency sound waves with low frequency sound waves.

C.

By making copies of the unwanted sound waves and letting them out a little later.

D.

By mixing new sound waves with the noise and sending them out together.

(2)

Besides its main function the noise-killing system can ________.

[  ]

A.

make a car lighter

B.

make a car quieter

C.

reduce the cost of a silencer

D.

improve the performance of a silencer

(3)

The noise-killing system is not yet popular mainly because ________.

[  ]

A.

it increases the cost of car production

B.

carmakers are not sure if it is necessary

C.

it is still being tried out

D.

people still have their doubts
