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
B. American western development
C. a tour along the Colorado River
D. a recently built bridge

第三部分阅读理解(共20小题,每小题2分,满分40分)
阅读下列短文,从题中所给的A、B、C、D四个选项中,选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑。
Scientists in Canada say big ocean fish have almost disappeared from the world since the start of
industrial fishing in the 1950s. The scientists found the populations of large fish like tuna(金枪鱼), swordfish and cod(鳕鱼) have dropped by ninety percent in the past fifty years.
The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.
The scientists say the common method called long line fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be nearly one hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.
Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. But long line fishing boats now might only catch one fish per hundred hooks.
The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.
Ransom Myers and Boris Worm of Dalhousie University in Nova Scotia led the study with the University of Kiel in Germany. Worm says the destruction could lead to a complete reorganization of ocean life systems. Meyers says the decreased numbers of large fish are not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors. He says not only are there fewer
big fish, but also they are smaller than those of the past.
American government scientists say even with the best efforts to protect fish populations, decreases are to be expected.
56. Which one can be the best title for the passage?
A. Discoveries Canadian scientists have made B. Japan fishing industry
C. Losses of big fish D. Modern fishing methods
57. When did the researchers begin to survey the decrease of large fish?
A. in the 1960s B. in the 1970s C. in the 1980s D. in the 1990s
58. The underlined word “sharp” in Para 3 means _________.
A. having a fine edge or point that can cut or make a hole in something
B. sudden or rapid change in something
C. quick to react or to understand things
D. loud, sudden and often high in tone
59. Which of the following statements can show the fact that the populations of large fish have dropped?
A. Today’s “large” fish are smaller th
an those of the past.
B. Long line fishing boats now might catch ten fish for every one hundred hooks.
C. Fish able to reproduce don’t have the chance to live longer.
D. Long line fishing boats now might catch one fish for every one hundred hooks
60. Where is the passage probably taken from?
A. A story book B. A business magazine C. An environmental report D. An economic survey
The evidence for harmony ( 和谐)may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image(形象) of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. "We were surprised by just how positive today's young people seem to be about their families," said one member of the research team. "They're expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There's more negotiation(商议) and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat."
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. "My parents are happy to discuss things with me and willing to listen to me," says 17-years-old Daniel Lazall. " I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with it." Susan Crome, who is now 21, agrees. "Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that."
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, "Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over."

查看习题详情和答案>>In 1955, a man named Raymond Kroc entered a partnership with two brothers named Mcdonald. They operated a popular restaurant in California which sold food that was easy to prepare and serve quickly. Hamburgers, French fries, and cold drinks were the main foods on the limited menu. Kroc opened similar eating places under the same name, “McDonald’s” and they were a quick success. He later took over the company and today it is one of the most famous and successful “fast-food” chains(连锁店) in America and the world.
Why was his idea so successful? Probably the most important reason was that his timing was right. In the 1950s, most married women stayed home to keep house and take care of their children. During the 1960s, the movement for equality(平等) between men and women and an economy(经济) that needed more families to have two money-earners resulted in many women returning to the workplace. This meant that they had less time and energy to do housework, so they depended more on fast-food restaurants.
Single parents also have little time to spend in the kitchen. People living alone because of divorce(离婚) or a preference for a “single lifestyle” also depend on this type of food, since cooking for one is often more trouble than it is worth.
Fast food is not part of the diet of all Americans. Another of the 1960s was called back-to-nature movement. More and more Americans based their diets on natural foods. This preference for natural foods continues to this day. These products can now be found not only in the special health food store but also in many supermarkets.
1.The passage is mainly about ____.
A.how and why “McDonald’s” became successful
B.the effect social and economic changes have on people’s eating habits
C.why Americans prefer natural food
D.American eating habits
2.Which of the following was NOT a reason for Raymond Kroc’s success?
A.His partnership with the McDonald brothers.
B.A changing economy.
C.The back-to-nature movement.
D.Women’s equality movement.
3.We can infer from the passage that ____.
A.natural foods can also be found in McDonald’s
B.many married women in America returned to work in the 1960s
C.McDonald’s fast food is popular among the young
D.divorce caused people to change their eating habits
