Exactly 20 years ago, a Time magazine cover s

20、tory announced that scientists are on the verge of being able to predict the time, place and even the size of earthquakes. “The people of quake-ravaged Kobe learned last week how wrong that assertion was.“None of the methods conceived two decades ago has yet to discover a uniform warning signal that

21、 preceded all quakes, let alone any sign that would tell whether the coming tremor is mild or a killer. Earthquake formation can be triggered by many factors, says Hiroo Kanamori, a seismologist at the California Institute of Technology. So, finding one all-purpose warning sign is impossible. One re

22、ason: Quakes start deep in the earth, so scientists can t study them directly. If a quake precursor were found, it would still be impossible to warn humans in advance of all dangerous quakes. Places like Japan and California are riddled with hundreds, if not thousands, of minor faults.Prediction wou

23、ld be less important if scientists could easily build structures to withstand tremors. While seismic engineering has improved dramatically in the past 10 to 15 years, every new quake reveals unexpected weaknesses in “quake-resistant“ structures, says Terry Tullis, a geophysicist at Brown University.

24、 In Kobe, for example, a highway that opened only last year was damaged. In the Northridge earthquake, on the other hand, well-built structures generally did not collapse.A recent report in science adds yet more anxiety about life on the faulty lines. Researchers ran computer simulations to see how

25、quake-resistant buildings would fare in a moderate-size tremor, taking into account that much of a quakes energy travels in a large “pulse“ of focused shaking. The results: Both steel-frame buildings and buildings that sit on insulating rubber pads suffered severe damage.More research will help expe

26、rts design stronger structures and possibly find quake precursors. But it is still a certainty that the next earthquakes will prove once again that every fault cannot be monitored and every highway cannot be completely quake-proofed.（分数：5.00）(1).From what the author said in Para. 1, it can be inferr

27、ed that _ .（分数：1.00）A.scientists can never be able to predict the coming of earthquakesB.the existing power on predicting earthquakes is somewhat exaggeratedC.quite a lot of scientific assertions are groundlessD.earthquake predictions are beyond the reach of scientists(2).One of the chief difficulti

28、es in accurate earthquake warning is that _ .（分数：1.00）A.earthquakes may take place in anywhere possibleB.earthquakes may happen at any unexpected momentC.most earthquakes take place simultaneously and unexpectedlyD.the occurrence of earthquakes involves too many unforeseen factors(3).What does the w

29、ord “precursor“ in the context in Para. 3 mean?（分数：1.00）A.A man that may come before the happening of an earthquake.B.The leading factor that may cause a series of events to occur.C.Any meaningful sign that indicates some would-be happenings.D.An event that may have symbolic or significant nature.(4

30、).What does the author mean to say when he talks about the damage caused by earthquakes to the buildings?（分数：1.00）A.It is hard to build structures strong enough to withstand serious tremors.B.Not all structures can be made to withstand the tremor of the earthquakes.C.The degree of damage caused by e

31、arthquakes to different buildings can hardly be predicted accurately.D.No structures would be strong enough to endure violent earthquakes.(5).All the following statements are TRUE except that _ according to the passage.（分数：1.00）A.stronger materials will be developed to withstand serious earthquakesB

32、.seismic engineering has been greatly improved in the past yearsC.it won t be long before earthquakes can be predicted accuratelyD.something unpredictable may still happen beyond the expectations of the seismologistBPassage 2/BWhen Jules Verne wrote Journey to the Center of the Earth in 1864, there

33、were many conflicting theories about the nature of the Earth s interior. Some geologists thought that it contained a highly compressed ball of incandescent gas, while others suspected that it consisted of separate shells, each made of different materials. Today well over a century later, there is li

34、ttle direct evidence of what lies beneath our feet. Most of our knowledge of the Earth s interior comes not from mines or boreholes, but from the study of seismic waves-powerful pulses of energy released by earthquakes.The way that seismic waves travel shows that the Earth s interior is far from uni

35、form. The continents and the seabed are formed by the crust-a thin sphere of relatively light, solid rock. Beneath the crust lies the mantle, a different layer that extends approximately halfway to the Earth s center. There the rock is the subject of a battle between increasing heat and growing pres

36、sure.In its high levels, the mantle is relatively cool; at greater depths, high temperatures make the rock behave more like a liquid than a solid. Deeper still, the pressure is even more intense, preventing the rock from melting in spite of a higher temperature.Beyond a depth of around 2,900 kilomet

37、ers, a great change takes place and the mantle gives way to the core. Some seismic waves cannot pass through the core and others are bent by it. From this and other evidence, geologists conclude that the outer core is probably liquid, with a solid center. It is almost certainly made of iron, mixed w

38、ith smaller amounts of other elements such as nickel.The conditions in the Earth s core make it a far more alien world than space. Its solid iron heart is subjected to unimaginable pressure and has a temperature of about 9,000F. Although scientists can speculate about its nature, neither humans nor

39、machines will ever be able to visit it.（分数：5.00）(1).What is today s richest source of information about the Earth s interior for geologists?（分数：1.00）A.Journey to the Center of the Earth, the book written by Jules Verne.B.Conflicting theories about the nature of the Earth s interior.C.The study of Se

40、ismic waves-powerful pulses of energy released by earthquakes.D.The theories that there is little direct evidence of what lies beneath our feet.(2).The word “There“, the first word in the last sentence of paragraph 2 refers to which of the following?（分数：1.00）A.A layer beneath the crust that extends

41、halfway to the Earth.B.A thin sphere of relatively light, solid rock with high temperature.C.The continents and the crust that are with both heat and pressure.D.Earth s center where the rock is the subject of battle between heat and pressure.(3).Which of the following is a primary characteristic of

42、the Earth s mantle?（分数：1.00）A.Light, solid rock.B.Uniformity of composition.C.Dramatically increasing pressure.D.Compressed, incandescent gas.(4).The phrase “gives way to“ in the paragraph 4 is closest in meaning to _ .（分数：1.00）A.runs alongB.turns intoC.rubs againstD.floats on(5).Why does the author

43、 state in the last paragraph that the Earth s core is “more alien“ than space?（分数：1.00）A.Government funds are not available to study the Earth s core.B.Scientists aren t interested in the characteristic of the Earth s core.C.It is impossible to go to the Earth s core to do research.D.The Earth s cor

44、e is made of elements that are dangerous to humans.BPassage 3/BMost scientists blame people, at least in part, for global warming. Now, some researchers say people may be partly to blame for the cooling of Antarctica as well.While average global temperatures have risen about one degree Fahrenheit ov

45、er the past century, Antarctica over all appears to have cooled slightly in the past few decades. That has been puzzling, because the polar regions are thought to be more sensitive to warming trends than the rest of the globe. Even more puzzling, a small portion of Antarctica-the peninsula that stre

46、tches north toward South America-defies the cooling trend. It has been warming very rapidly, about five degrees over the past 50 years, 10 times the global average.Writing in today s issue of the journal Science, Dr. David Thompson, a professor of atmospheric science at Colorado State University, an

47、d Dr. Susan Solomon, a senior scientist at the National Oceanic and Atmospheric Administration in Boulder, Colo., argue that the ozone hole, which has opened up each spring over Antarctica in recent years, may help explain both contradictory trends.A vortex of winds continually blows around Antarcti

48、ca, tending to trap cold air at the South Pole. In the new paper, Dr. Thompson and Dr. Solomon show that the winds have strengthened in the past few decades, keeping the cold air even more confined. The peninsula, which lies outside the wind vortex, escapes the cooling effect, the scientists said. They say the ozone hole may be the cause of the stronger
