The dramatic 53 decline in vulture numbers is causing widespread disruption to people living in the same areas as the birds .It is also causing serious public health problems 54 across the Indian sub-continent.55While their reputation and appearance may be 56 unpleasant _ to many Indians, vultures have long 57played a very important role in keeping towns and villages all over India clean. It is because they feed on dead cows. In India, cows are sacred animals and are traditionally left in the open when they die in their thousands 58upon thousands every year.The disappearance of the vultures has led to an explosion in the _ 59numbers of wild dogs feeding on the remains of these dead animals. There are fears that rabies may increase as a 60 result . And this terrifying disease may ultimately affect humans in the region, since wild dogs are its main carriers. Rabies could also spread to other animal species, causing an even greater problem in the future.The need for action is _ 61urgent , so an emergency project has been launched to _ 62find a solution to this serious vulture problem. Scientists are trying to identify the diseasecausing the birds’ deaths and, if possible, develop a cure.Large-scale vulture 63 deaths were first noticed at the end of the 1980s in India. A population survey at that time showed that the three species of vultures had 64declined by over 90 per cent. All three species are now listed as "critically endangered". As most vultures lay only single eggs and take about five years to reach maturity, reversing their population decline will be a long and 65 difficult exercise.理工类C级全真模拟试题(一)When Our Eyes Serve Our Stomach(出自教材内的新增文章*)Our senses aren’t just delivering a strict view of what’s going on in the world; they’re affected by what’s going on in our heads.31. What does the new study mentioned in Paragraph l find?C Hungry people are more sensitive to food-related words than stomach-full people.32. Why was there a delay on the day of the experiment?B Because Radel wanted to create two groups of testees, hungry and non-hungry.33. What does the writer want to tell us?C Human brains can really be at the disposal of our motives and needs.34. What did the results of the experiment indicate?A80 words flashed on the screen too fast for the participant to intentionally perceive.35. What can we infer from the passage?D Humans can perceive what they need without involving high-level thinking processesEgypt felled by Famine(出自教材内的文章)Even ancient Egypt’s mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC .Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same or worse could happen today.41. Why does the author mention ―pyramid builders‖?D. Because even they were unable to rescue their civilization.42.Which of the following factors was ultimately responsible for the fall of the civilization of ancient Egypt?A. Change of climate.43. Which of the following statements is true?D. The White Nile and the Blue Nile are branches of the River Nile.44. According to Krom, Egyp t’s Old Kingdom fell.A. immediately after a period of drought45. The word ―devastating‖ in the last paragraph could be best replaced by.B. ―damaging‖Giant Structures(出自教材内的新增文章*)It is an impossible 51 task to select the most amazing wonders of the modern world since every year more wonderful constructions appear. Here are three giant structures which are 52 worthy of our admiration although they may have been53 surpassed by some more recent wonders.The Petronas T win T owersThe Petronas Towers were the 54 tallestt buildings in the world when they were completed in 1999. With a height of 452 metres, the tall twin towers, like two thin pencils, dominate the city of Kuala Lumpur. At the 41st floor, the towers are linked by a bridge, symbolizing a gateway to the city. The American architect Cesar Pelli 55designed the skyscrapers.Constructed of high-strength concrete, the building provides around l, 800 square metres of office space on every floor. And it has a shopping centre and a concert hall 56at the base. Other features 57features of this impressive building include double-decker lifts, and glass and steel sunshades.The Millau BridgeThe Millau Bridge was opened in 2004 in the Tarn V alley, in southern France.At the time it was built, it was the world's58 highest bridge,reaching over 340m at the highest point. The bridge is described as one of the most amazingly beautiful bridges in the world. It was built to relieve Millau's congestion problems. The congestion was then59 caused by traffic passing from Paris to Barcelona in Spain. The bridge was built to 60withstand the most extreme seismic and climatic conditions. 61Besides , it is guaranteed for 120 years!The Itaipu DamThe Itaipu hydroelectric power plant is one of the largest constructions of its kind in the world. It consists of a series of dams across the River Parana, which forms a natural border betweenBrazil6 and Paraguay. Started in 1975 and taking 16 years to complete, the constructionwas carried62out as a joint project between the two countries . The dam is well-known for both its electricity output and its size. In 1995 it produced 78% 0f Paraguay's and 25% 0f Brazil's energy 63energy needs. In its construction, the amount of iron and steel used was 64equivalent to over 300 Eiffel Towers. It is a truly amazing wonder of 65engineering .理工类C级全真模拟题（三）Winged Robot Learns to Fly(出自教材的文章)Learning how to fly took nature millions of years of trial and error—but a winged robot has cracked it in only a few hours, using the same evolutionary principles.31. Which of the following is NOT true of what is mentioned about the winged robot in thesecond paragraph?C. The two professors of CUT programmed the data on how the robot flapped its wings.32. How did the robot behave at the beginning of the test?B. It twitched but gradually gained height33. Which of the following is nearest to Peter Bentley’s view on the winged robot?A. The winged robot could never really fly.34. What measured how much lift the robot produced?B. A movement detector35. What does ―the process‖ appearing in the last paragraph refer to?D. All the above.Wonder Webs(出自教材内的文章)Spider webs are more tha n homes, and they are ingenious traps. And the world’s best web spinner may be the Golden Orb Weaver spider. The female Orb Weaver spins a web of fibers thin enough to be invisible to insect prey, yet __51tough __ enough to snare a flying bird without breaking.The secret of the web’s strength? A type of super-resilient _52silk__ called dragline. When the female spider is ready to __53weave__ the web’s spokes and frame, she uses her legs to draw the airy thread out through a hollow nozzle in her belly. Dragline is not sticky, so the spider can race back and forth along __54 her__ to spin the web’s trademark spiral.Unlike some spiders that weave a new web every day, a Golden Orb Weaver __55reuses __ her handiwork until it falls apart, sometimes not for two years. The silky thread is five times stronger than steel by weight and absorbs the force of an impact three times better than Kevlar, a high-strength human-made _56_material_ used in bullet-proof vests. And thanks to its high tensile strength, or the ability to resist breaking under the pulling force called tension, a single strand can stretch up to 40 percent longer than its original __57length__ and snap back as well as new. No human-made fiber even comes __58_ close_.It is no __59_ wonder_ manufacturers are clamoring for spider silk. In the consumer pipeline: high-performance fabrics for athletes and stockings that never run. Think parachute cords and suspension bridge cables. A steady _ _60_ supply_ of spider silk would be worth billions of dollars – but how to produce it? Harvesting silk on spider farms does not _61 work__ because the territorial arthropods have a tendency to devour their neighbors.Now, scientists at the biotechnology company Nexia are spinning artificial silk modeled after Golden Orb dragline. The __62first __ step: extract silk-making genes from the spiders. Next, implant the genes into goat egg cells. The nanny goats that grow from the eggs secrete dragline silk proteins in their _ 63_milk_. ―The young goats pass on the silk-making gene without __64_ any_ help from us,‖ says Nexia president Jeffrey Turner. Nexia is still perfecting the spinning process, but they hope artificial spider silk will soon be snagging customers _65_as fast as_ the real thing snags bugs.。
