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.
1.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.
2.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.
3.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
4.Which of the followings shows the right position of the bridge and dam?
5.The text is mainly about ______.
A. the Hoover Dam

根据短文内容，完成下面表格。
Many people believe in the existence of an animal that is half human and half ape(猿)．
In 1958 a young man named Jerry Crew was on his way to work．Mr．Crew worked for the Wallace Construction(建筑)Company in California．He drove large construction equipment for the company．It had rained for the past several days and the area was very wet and muddy(泥泞的)．
As Jerry Crew walked toward the vehicle he would drive that day, he saw something extremely unusual．What he saw frightened him．There, in the mud, were footprints－footprints that were almost ten times larger than a normal human foot．
Newspaper reporters found out about the huge footprints．They talked to Mr．Crew and took pictures of the footprints．They published stories all over California．One newspaper story called the creature that made the prints “Bigfoot”．
In 1967 a man named Roger Patterson used a small movie camera to take pictures of an ape-like creature moving from a clear area into a forest．Many people said this proved Bigfoot was real．
In 2002 a man named Ray Wallace died of heart failure．He was the man who owned the Wallace Construction Company．Soon after his death, his family told reporters that Mr．Wallace had invented Bigfoot as a joke．They told how he had made huge feet out of wood and tied them to his shoes．They said Ray Wallace left the footprints that Jerry Crew found．
The Wallace family said the joke became bigger and bigger and Ray Wallace just could not stop．He was having too much fun．For example, in 1967 he dressed his wife in a monkey suit with large feet．Ray Wallace and Roger Patterson filmed her walking into the woods．
Many people say the Wallace family were lying．These people plan to continue their search for Bigfoot．Several organizations are still searching for the creature．Chinese scientists are gathering evidence and reason to believe there is Bigfoot living in the mountains of Hubei Province．
