A new eight-kilometer road is under construction that links the port area with motorway system. It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city. As part of the project, two four-kilometer road tunnels are being built below the central area of the city, one for traffic to the north and the other for the traffic to the south. The two tunnels are about 20 meters below the surface and are 12 meters wide, providing for two lanes of traffic in each direction.
In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electric signs at frequent intervals. They show traffic conditions ahead and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproofing covering and, on the inside of the tunnel, a concrete lining（混凝土衬砌）.
Each tunnel is roughly round and the lower part of the tunnel is somewhat flat. The surface of the road lies on the base, which is made of concrete and steel. The drainage system, just below the road surface on one side, removes any extra liquid, particularly water. In the event of fire, the fire main, which is made of steel, pipes water to many fire hydrant stations at regular intervals along the length of the tunnel. The fire main is at the side of the tunnel and at the level of the road surface. Other systems in the tunnel will include emergency phones.
72. Each of the tunnels under construction is _____.
A. eight kilometers long and twenty meters wide    B. eight kilometers long and six meters wide
C. four kilometers long and twenty meters wide     D. four kilometers long and six meters wide
73. Which part of the tunnel in the diagram is used to pipe out extra water?
A. 1          B. 3            C. 5              D 6
74. Driving in the tunnel, one can know the traffic conditions ahead through______.
A. the lights                   B. the electric signs
C. the trucks and the cars         D. the emergency phones
75. The passage is mainly about _____.
A. the construction of a road                        B. the design of a road
C. the construction of two tunnels          D.the design of two tunnels

Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs’fossils(恐龙化石) because dinosaurs died out millions of years ago.
It’s very difficult for the scientists to reach an agreement because different results can be got from the same fossils, Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck(陷入)all at once, or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.
Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. “That’s pretty much settled at this point.” Says Paul Sereno, A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.
As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs ― birds and crocodiles ― for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.
There is still a long way to go before the above questions could be answered. Dinosaur scientists will have to find more proof to reach an agreement.
60.Dinosaur scientists can get information directly by           .
A.  studying dinosaur fossils                B. examining modern animals
C. watching dinosaurs                         D. using telescopes
61.What is pretty much settled according to Paul Sereno?
A. Half of the dinosaurs lived alone.    B. Most dinosaurs moved long distances.
C. Many dinosaurs settled in the north. D.Some dinosaurs lived in big groups.
62.Dinosaur scientists can probably know whether dinosaurs were good parents by              .
A. watching many kinds of animals      B. studying dinosaurs’living relatives
C. following the tracks left behind              D. working on dug-out dinosaur eggs
63.Which of the following the according to the paragraph?
A. Birds hardly ay attention to their young. B. Baby crocodiles can look after themselves well.
C. Some dinosaurs took care of their young.       D. Birds and crocodiles take good care of their young.

Researchers are placing robotic dogs (机器狗) in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激) ,” Edwards points out. “The problem is how we promote(使……成为现实)that, especially for those without friends or help. A robotic dog could be a solution.”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady.“When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own.”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry,” Beck says. “But it’s amazing how quickly we have given up that belief.
“Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds.”
48. The purpose of Beck and Edwards’ study is to ______
A. understand human-animal relationship       B. make lonely old people’s life better
C. find the causes of old people’s loneliness    D. promote the animal-assisted research
49. In the research, the old people are asked to ______
A. note the activities of AIBOs                      B. keep AIBOs at home for 12 weeks
C. record their feelings and activity               D. analyze the collected information
50. What is the advantage of AIBO over live dogs?
A. It is easier to keep at home.                      B. It can help the disabled people.
C. It responds to all the human orders.           D. It can watch TV with its owner.
51. The author seems to suggest that the future robotic dogs may ______
A. cure certain diseases                                B. keep old people active
C. change people’s beliefs                             D. look more like real dogs

If you are lost in the mountains, stay calm in the face of darkness, loneliness, and the unknown. It will greatly increase your chances of survival (生存). Many people think that preparing necessary equipment and knowing how to use it are very important, but actually eighty percent of mountain survival is your reaction to fear.
Find a hiding place.
Unnecessary labor will make you sweat and make you cold. Find a hiding place around you before trying to start your own construction. If you are in a snow-covered area, you may be able to dig a cave in deep snow for protection from the wind. You should try to hide yourself in the middle of the mountain if possible. Stay out of the valleys — cold air falls, and the valley floor can be the coldest area on the mountain.
Signal rescuers for help.
The best time to signal rescuers is during the day. Signal for help from the highest point possible — it will be easier for rescuers to see you, and any sound you make will travel farther. If you take a box of matches and a space blanket (a special blanket for traveling), build three smoky fires and put your blanket — gold side facing out — on the ground.
Do not walk away.
It will make finding you more difficult, as search teams will be trying to follow your path and may miss you if you have gone off in a different direction. Searchers often end up finding a car with no one in it.
If you get frostbite (冻伤), do not rewarm the affected area until you’re out of danger.
You can walk on frostbitten feet, but once you warm the area and can feel the pain, you will not want to walk anywhere. Try to protect the frostbitten area and keep it dry until you are rescued.
36. When lost in the mountains, you can increase your chances of survival if you      .
A. take a space blanket with you            B. do more physical labor
C. try to find a car immediately                    D. walk as far as possible to find help
37. According to the passage, people most probably fail to survive if they      .
A. do not take enough equipment           B. stay in the middle of the mountain
C. do not keep themselves warm            D. stay in a snow-covered area
38. What can we infer from the passage?
A. Don’t travel by yourself.                   B. Mountain traveling is dangerous.
C. Don’t get frightened in danger.          D. Avoid going to unfamiliar places.

A study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities (个性) and food experiences. “One week later,” Loftus says, “we told those people we'd fed their answers into our smart computer and it came up with an account of their early childhood experiences.” Some accounts included one key additional detail (细节): “You got sick after eating strawberry ice-cream.” The researchers then changed this detail into a manufactured (人为促生的) memory through leading questions—Who were you with? How did you feel? By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it.
When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it's not that easy. False memories appear to work only for foods you don't eat on a regular basis. But most important, it is likely that false memories can be implanted (灌输) only in people who are unaware of the mental control. And lying to a patient is immoral, even if a doctor believes it's for the patient's benefit.
Loftus says there's nothing to stop parents from trying it with their overweight children. “I say, wake up—parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that's a more moral lie. Decide that for yourself.”
72. Why did Loftus ask the volunteers to answer some questions?
A. To improve her computer program.           B. To find out their attitudes towards food.
C. To find out details she can make use of             D. To predict what food they'll like in the future.
73. What did Loftus find out from her research?
A. People believe what the computer tells them.
B. People can be led to believe in something false.
C. People tend to forget their childhood experiences.
D. People are not always aware of their personalities.
74. According to the study, people may stop having a certain food if they ________.
A. learn it is harmful for health
B. lie to themselves that they don't want it
C. are willing to let doctors control their minds
D. think they once had a bad experience of eating it
75. What is the biggest concern with the method?
A. Whether it is moral.                                B. Who it is best for.
C. When it is effective.                                D. How it should be used.
