“Liquefaction” Key to Much of Japanese Earthquake DamageThe massive subduction zone earthquake in Japan caused a significant level of soil “liquefaction” that has surprised researchers with its 51 severity, a new analysis shows.“We’ve seen localized examples of soil liquefaction as extreme as this before, but the distance and 52 of damage in Japan were unusually severe,” said Scott Ashford, a professor of geotechnical engineering at Oregon State University. “Entire structures were tilted and sinking into the sediments,” Ashford said. “The shifts in soil des troyed water, drain and gas pipelines, crippling the utilities and infrastructure these communities need to 53 . We saw some places that sank as much as four feet.”Some degree of soil liquefaction is common in almost any major earthquake. It’s a phenome non in which soils soaked with water, particularly recent sediments or sand, can lose much of their 54 and flow during an earthquake. This can allow structures to shift or sink or 55 .But most earthquakes are much 56 than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this.“With such a long-lasting earthquake, we saw 57 structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes,” he said. “And it was clear that younger sediments, and especially areas built on 58 filled ground, are much more vulnerable.”The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil 59 and better prepare for it in the future. Ashford said it was critical for the team to collect the information quickly, 60 damage was removed in the recovery efforts.“There’s no doubt that we’ll learn things from what happened in Japan that will help us to reduce risks in other similar 61 ,” Ashford said. “Future construction in some places may make more use of techniques known to reduce liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns.”Ashford pointed out that northern California have younger soils vulnerable to liquefaction-on the coast, near river deposits or in areas with filled ground. The “young” sediments, in geologic terms, may be those 62 within the past 10, 000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities.Anything 63 a river and old flood plains is a suspect, and the Oregon Department of Transportation has already concluded that 1, 100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have beenreinforced to 64 collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction 65 helped prevent many buildings from collapse-even as they tilted and sank into the ground.51.A. internal B. different C. difficult D. widespread52.A. volume B. length C. extent D. width53.A. function B. repair C. build D. remove54.A. durability B. strength C. ability D. property55.A. ascend B. compact C. collapse D. recover56.A. shorter B. longer C. simpler D. stranger57.A. when B. what C. how D. which58.A. occasionally B. frequently C. specially D. recently59.A. development B. phenomenon C. formation D. composition60.A. unless B. until C. after D. before61.A. findings B. locations C. events D. sources62.A. delivered B. deposited C. destroyed D. detached63.A. near B. from C. inside D. over64.A. prevent B. accelerate C. predict D. detect65.A. styles B. sites C. costs D. standards参考答案：51-65 DCABC ACDBD CBAAD。

职称英语等级理工类(A级)试题考试试题答案及题解4第二篇A Phone That Knows You’re BusyIt’s a modern problem：you’re too busy to be disturbed by incessant(连续不断的)phone calls so you turn your cellphone off .But if you don’t remember to turn it back on when you’re less busy．you could miss some important calls if only the phone knew when it was wise to interrupt you，you wouldn’t have to turn it off at all. Instead，it could let calls through when you are not too busyA bunch of behavior sensors(传感器)and a clever piece of software could do just that，by analyzing your behavior to determine if it’s a good time to interrupt you．If built into a phone，the system may decide you’re too busy and ask the caller to leave a message or ring back later．James Fogarty and Scott Hudson at Camegie Mellon University in Pennsylvania based their system oil tiny microphones，cameras and touch sensors that reveal body language and activity．First they had to study different behaviors to find out which ones stongly predict whether your mind is interrupted.The potential“busyness”signals they focused on included whether the office doors were left open or closed，the time of day，if other people were with the person in question，how close they were to each other, and whether or not the computer was in use．The sensors monitored these and many other factors while four subjects were at work . At random intervals，the subjects rated how interruptible they were on a scale ranging from“highly interruptible’’to“highly not—interruptible” . Their ratin gs were then correlated with the various behaviors . “It is a shotgun(随意的)approach：we used all the indicators we could think of and then let statistics find out which wereimportant，” says Hudson.The model showed that using the keyboard，and talking on a landline or to someone else in the office correlated most strongly with how interruptible the subjects judged themselves to be．Interestingly，the computer was actually better than people at predicting when someone was too busy to be interrupted . The computer got it right 82 per cent of the time，humans 77 per cent．Fogarty speculates that this might be because people doing the interrupting are inevitably biased towards delivering their message，whereas computers don’t care．The first application for Hudson and Fogarty’s system is likely to be in an instant messaging system，followed by office phones and cellphones．“There is no technological roadblock(障碍) to it being deployed in a couple of years，” says Hudson36 A big problem facing people today is thatA they must tolerate phone disturbances or miss important calls．B they must turn off their phones to keep their homes quiet．C they have to switch from a desktop phone to a cellphone．D they are too busy to make phone calls．37 The behavior sensor and software system built in a phoneA could help store messages．B could send messages instantlyC could tell when it is wise to interrupt you．D could identify important phone calls．38 Scientists at Carnegie Menon University tried to find outA why office doors were often 1eft open．B when it was a good time to turn off the computer．C what questions office workers were bothered with．D which behaviors could tell whether a person was busy39 During the experiment，the subjects were askedA to control the sensors and the camera．B to rate the degrees to which they could be interrupted．C to compare their behaviors with others’.D to analyze all the indicators of interruption．40 The computer performed better than people in the study becauseA the computer worked harder．B the computer was not busyC people tended to be biased．D people were not good at statistics．。

They may use 2 currencies, but these countries, and probably all countries, still have one thing in common1： Germs on the banknotes.Scientists have been studying the germs on money for well over2 100 years. At the turn of the 20th 3 , some researchers began to suspect that germs living on money could spread disease.Most studies of germy money have looked at the germs on the currency 4 one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5 .Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6 from 10 nations. The scientists studied 1,280 banknotes in total; all came from places where people buy food, like supermarkets street vendors and cafes, 7 those businesses often rely on cash.Overall, the Australian dollars hosted the fewest live bacteria ---- no more than 10 per square centimeter. Chineseyuan had the most ---- about 100 per square centimeter. Most of the germs on money probably would not cause harm.Wh at we call “paper” money usually isn't made from paper. The U. S. dollar, for example, is printed on fabric that is mostly 8 .Different countries may use different 9 to print their money. Some of the currencies studied by Vriesekoop and his 10 such as the American dollar were made from cotton. Others were made from polymers.The three 11 with the lowest numbers of bacteria were all printed on polymers. They included the Australian dollar, the New Zealand dollar and some Mexican pesos.The other currencies were printed on fabric made 12 of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13 have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand how germs live on money-----and whether or not we need to be concerned. Vnesekoop is now starting a study that will 14 the amounts of time bacteria can stay alive on different types of bills.Whatever Vriesekoop finds, the fact remains： Paper money harbors germs We should wash our 15 after touching it; after all5, you never know where your money 's been.

2020职称英语考试《理工类》A级完形填空专项模拟题(4)Earth's Inner CoreScientists have long struggled to understand what lies at the planet's center. Direct observation of its center is impossible, so researchers must (1) to other evidence.In 1889, a German scientist detected a severe earthquakein Japan. Geophysicists concluded that shock waves (2) jolts (晃动) from one side of Earth through the center to the other side. Then in 1936, Danish geophysicist Inge Lehmann studied the waves' (3) to determine that within Earth's core ofmolten (熔化了的) iron lies a solid inner core - but (4) that core was made of eluded (难倒) her. Other geophysicistsquickly determined that Lehmann's inner core was composed mostly (5) iron. Since then, Lehmann's discovery has (6) conventional Earth science.But now scientists are challenging traditional theorywith new and radical (7). For example, Earth's center could actually contain an "inner core within the inner core," claim Ishii and colleague Adam Dziewonski.Analyzing hundreds of thousands of earthquake wave (8), they maintain that the inner core has at its heart a tiny, even more solid sphere (球体). This sphere "may be the oldest fossil (9) from the formation of Earth," says Dziewonski.Dziewonski and Ishii speculate that shortly (10) Earth formed around 4.8 billion years ago, a giant asteroid (小行星)smashed into the young planet and nearly melted it. ButEarth's center didn't quite melt; it (11) mass as the planet cooled. The core within a core may be the kernel (核心) that endured. "Its presence could change our basic ideas about the (12) of the planet," Dziewonski says.Dziewonski's idea is tame (温和的) compared to the (13) theories of independent geophysicist J. Marvin Herndon.Earth's inner core is made not of iron, he claims, but a (14) of nickel and silicon. Herndon has a truly revolutionary notion： Within the nickel silicide (硅化物) inner core is also an "inner" inner core - an 8 km-wide ball of the element uranium. Uranium is radioactive. Herndon thinks the uranium releases heat energy as its atoms (15) fission-split and crash into one another in a chain reaction. In other words, we may live on top of a gigantic, "natural" nuclear power plant.1 A try B leave C turn D point2 A create B receive C feel D overcome3 A work B solution C job D patterns4 A whether B what C why D how5 A from B within C of D to6 A followed B dominated C restored D opposed7 A ideas B demands C phenomena D movements8 A things B acts C methods D records9 A taken B benefited C left D kept10 A after B before C since D when11 A expanded B modified C gained D melted12 A size B origin C structure D shape13 A radical B traditional C classical D conventional14 A system B copy C model D compound15 A charge B last C experience D show参考答案：1.
