Choose the best answer and mark your answer on the Answer Sheet.Passage OneSometimes a race is not enough. Sometimes a runner just wants to go further. That‘s what happened to Dennis Martin and Brooke Curran.Martin, 68, a retired detective form New York City, took up running after his first wife died. Curran, 46, a philanthropist (慈善家) from Alexandria, started running to get out of the house and collect her thoughts. Both she and Martin got good at running but felt the desire to do more. ―The more I trained, the better I got,‖ Curran said,‖but I would cross the finish line with no sense of accomplishment.‖Eventually , they worked up to running marathons (马拉松) (and longer races) in other countries, on other countries. Now both have achieved a notable -and increasingly less rate- milestone; running the 26.2-mile race on all seven continents.They are part of a phenomenon that has grown out of the running culture in the past two decades, at the intersection of athleticism and leisure: ―runcations,‖ which combine distance running with travel to exotic places.There trips, as expensive as they are physically challenging, are a growing and competitive market in the travel industry.―In the beginning, running was enough,‖ said Steen Albrechtsen, a press manager. The classic marathon wasthe ultimate goal, then came the super marathons, like London and New York. But when 90,000 people a year can take that challenge, it is no longer exciting and adventurous .Hence, the search for new adventures began.‖―No one could ever have imagined that running would become the lifestyle activity that it is today,‖saidThom Gilligan, founder and president of Boston-based Marathon Tours and Travel. Gilligan, who has been in business since 1979, is partly responsible for the seven-continent phenomenon.It started with a casual talk to an interviewer about his company offering trips to every continent except Antarctica. And then in 1995, Marathon fours hosted its first Antarctica Marathon on King George Island. Off the tip of the Antarctic Peninsula; 160 runners got to the starting line of a dirt-and ice-trail route via a Russian icebreaker through the Drake Passage.21. At the beginning, Martin took up running just to .A. meet requirements of his jobB. win a running raceC. join in a philanthropic activityD. get away from his sadness22. Martin and Curran are mentioned as good examples of .A. winners in the 26.2-mile race on all seven continentsB. people who enjoy long running as a lifestyle activityC. running racers satisfied with their own performanceD. old people who live an active life after retirement23. A new trend in the travel industry is the development of .A. challenging runcationsB. professional racesC. Antarctica travel marketD. expensive tours24. The classic marathon no longer satisfies some people because .A. it does not provide enough challengeB. it may be tough and dangerousC. it involves too fierce a competitionD. it has attracted too many people25. The first Antarctica Marathon on King George Island indicates that .A. international cooperation is a must to such an eventB. runcations are expensive and physically challengingC. Marathon Tours is a leader of the travel industryD. adventurous running has become increasingly popularPassage TwoBefore the 1970s, college students were treated as children. So many colleges ran in loco parentis system. ―Inloc o parentis‖is a Latin term meaning ―in the place of a parent.‖It describes when someone else acceptsresponsibility to act in the interests of a child.This idea developed long ago in British common law to define the responsibility of teachers toward their students. For years, American courts upheld in loco parentis in cases such as Gott versus Berea College in 1913.Gott owned a restaurant off campus. Berea threatened to expel students who ate at places not owned by the school. The Kentucky high court decided that in loco parentis justified that rule.In loco parentis meant that male and female college students usually had to live in separate buildings. Women had to be back at their dorms by ten or eleven on school nights.But in the 1960s, students began to protest rules and restrictions like these. At the same time, courts began to support students who were being punished for political and social dissent.In 1960, Alabama State College expelled six students who took part in a civil rights demonstration. They sued the school and won. After that it became harder and harder to defend in loco parentis.At that time, students were not considered adults until 21. Then, in 1971, the 24th amendment to the Constitution set the voting age at eighteen. So in loco parentis no longer really applied.Slowly, colleges began to treat students not as children, but as adults. Students came to be seen as consumers of educational services.Gary Dickstein, an assistant vice president at Wright State University in Dayton, Ohio, says in loco parentis is not really gone. It just looks different. Today‘s parents, he says, are often heavily involved in students‘lives. Theyare known as ―helicopter parents.‖They always seem to hover over their children. Gary Dickstein says these parents are likely to question decisions, especially about safety issues and grades. They want to make sure their financial investment is not being wasted.26. Before the 1970s, many colleges ran in loco parentis system because .A. they could take the place of the students‘parentsB. parents asked them to do it for the interests of their childrenC. this was a tradition established by British collegesD. college students were regarded as too young to be treated as adults27. Who won the case of Gott versus Berea College in 1913?A. Berea College.B. Gott.C. It was a win-win case.D. The students.28. The word ―dissent‖(Para.5) probably means ―‖.A. extreme behaviorsB. violation of lawsC. strong disagreementD. Wrong doings29. In 1960,the court ruled that Alabama State CollegeA. had no right to expel the studentsB. was justified to have expelled the studentsC. shouldn‘t interfere with students‘ daily lifeD. should support civil rights demonstrations30. According to Gary Dickstein, today‘s―helicopter parents_____A. don‘t set their hearts at rest with college administratorsB. keep a watchful eye on their children‘s life and studyC. care less about their children‘s education than beforeD. have different opinions on their children‘s educationPassage ThreeWe tend to think of plants as the furniture of the natural world. They don‘t move they don‘t make sounds; they don‘t seem to respond to anything –at least not very quickly. But as is often the case, our human view of the world misses quite a lot. Plants talk to each other all the time. And the language is chemical.Over the years scientists have reported that different types of plants, from trees to tomatoes, release compounds into the air to help neighboring plants. These chemical warnings all have the same purpose—to spread information about one plant‘s disease so other plants can defend themselves. But exactly how plants receive and act on many of these signals is still mysterious.In this week‘s Proceedings of the National Academy of Sciences, researchers in Japan offer some explanations. They have identified one chemical message and traced it all the way from release to action.The scientists looked at tomato plants infested (侵害) by common pest, the cutworm caterpillar (毛虫). To start out, they grew plants in two plastic compartments connected by a tube. One plant was infested and placed upwind and the others were uninfested and placed downwind. The downwind plants were later exposed to the cutworm caterpillar. The results showed that plants that had previously been near sick neighbors were able to defend themselves better against the caterpillar.The researchers also studied leaves from exposed and unexposed plants. They found one compound showed up more often in the exposed plants. The substance is called Hex Vic. When the scientists fed Hex Vic to cutworms, it knocked down their survival rate by 17%. The scientists identified the source of Hex Vic, and sprayed it lightly over healthy plants. Those plants were then able to start producing the caterpillar-killing Hex Vic. Researchers confirmed that uninfested plants have to build their own weapon to fight off bugs and diseases. How do they know when to play defense? They are warned first by their friendly plant neighbors.It is a complex tale, and it may be happening in more plant species than tomatoes. It may also be happening with more chemical signals that are still unknown to us. For now though, we know that plants not only communicate, they look out for one another.31. What does the author try to emphasize Paragraph 1?A. How plants communicate is still a mystery.B. Enough attention has been paid to plant talk.C. Plants are the furniture of the natural world.D. Plants can communicate with each other.32. According to Paragraph2, what remains unknown is ______A. how plats receive and handle the signals from their neighborsB. why plants spread chemical information to their neighborC. how many types of plants release compounds into the airD. whether plants send chemical warnings to their neighbors33. The tomato plants in the experiment were ______A. placed separately but connected through airB. expose to different kinds of pestsC. exposed to the pest at the same timeD. placed together in a closed compartment34. The experiment shows that the infested plant helps its neighbors by ______A. making more Hex Vic to attract the pestB. releasing Hex Vic into the air to warn themC. letting them know how to produce Hex VicD. producing enough Hex Vic to kill the pest35.What may be the best title for the passage?A. Survival of PlantsB. Plant WorldC. Talking PlantsD. Plant Bug KillerPassage FourVancouver is the best place to live in the Americas; according to a quality-of-life ranking published earlier this month .The city regularly tops such indexes as its clean air, spacious homes and weekend possibilities of sailing and skiing. But its status as a liveable city is threatened by worsening congestion (拥挤). Over the next three decades, another 1 million residents are expected to live in the Greater Vancouver region, adding more cars, bicycles and lorries to roads that arc already struggling to serve the existing 2.3 million residents.A proposal by Vancouver‘s may orseeks to prevent the worsening conditions. Upgrades would be made to2,300 kilometres of road lanes, as well as bus routes and cycle paths. Four hundred new buses would join the fleet of 1,830. There would be more trains and more ―sea bus‖ferry crossing s between Vancouver and its wealthynorthern suburbs. To get all that, residents must vote to accept an increase in sales tax, from 7% to 7.5%. Polls suggest they will vote no.Everyone agrees that a more efficient transport system is needed. Confined by mountains to the north, the United States to the south and the Pacific Ocean to the west, Vancouver has spread in the only direction where there is still land, into the Fraser Valley, which just a few decades ago was mostly farmland. The road is often overcrowded.Yet commuters‘suspicion of local bureaucrats may exceed their dislike of congestion. TransLink, which runs public transport in the region, is unloved by taxpayers. Passengers blame it when Skytrain, the light-rail system, comes to a standstill because of mechanical or electrical faults, as happened twice in one week last summer, leaving commuters stuck in carriages with nothing to do but expressing their anger on Twitter. That sort of thing has made voters less willing to pay the C$7.5 billion in capital spending that the ten-year trafficupgrade would involve.Despite the complaints, Vancouver‘s transport system is a decent, well-integrated one on which to build,reckons Todd Litman, a transport consultant who has worked for TransLink. ―These upgrades are all-important ifVancouver wants to maintain its reputation for being a destination others want to go to.‖He says.36. The biggest problem threatening Vancouver as a liveable city is .A. increasing congestionB. climate changeC. shortage of landD. lack of money37. The upgrade proposal by Vancouver‘s mayor may be turned down by residents because .A. they do not want more people to move inB. they are reluctant to move to new placesC. upgrades would take away their living spaceD. upgrades would add to their financial burdens38. The only direction for Vancouver to further expand is towards .A. the eastB. the westC. the southD. the north39. TransLink is mentioned (Para.4) as an example of .A. world famous transport companiesB. local residents‘complaints about the bureaucratsC. local effort to improve public transportD. worsening traffic congestion40. According to Todd Litman, the upgrade proposal .A. will solve the traffic problemB. will benefit local economyC. satisfies the transport companyD. deserves public supportSection BDirections: In this section, you are required to read one quoted blog and the comments on it. The blog and comments are followed by questions or unfinished statements, each with four suggested answers A, B, C and D Choose the best answer and mark your answer on the Answer Sheet.Towards the end of the 1990s, more than a decade and a half Diet Coke was first introduced, sale of Coca Cola‘s best-selling low caloric drink appeared to slow down.However, in the decade that followed, diet sodas grew by more than 30 percent. In 2009, sales pushed above $8.5 billion for the first time. But America‘s thirst for Diet Coke is running dry a gain-and this time it could be forgood.The diet soda slowdown isn‘t merely an American thing- it‘s also happening worldwide. But the future of dietcolas is particularly cloudy in the United States.Low calorie sodas are fighting a hard battle against not one but two trends among American consumers. The first is that overall soda consumption has been on the decline since before 2000. Diet sodas, though they might come sugar- and calorie-free, are still sodas, something Americans are proving less and less interested in drinking.The second, and perhaps more significant trend, is a growing mistrust of artificial sweeteners(甜味剂). ―Consumers‘attitudes towards sweeteners have really changed.‖said Howard Telford, an industry analyst.―There‘s a very nega tive perception about artificial sweeteners. The industry is still trying to get its head around this.‖Comment 1Add me to the number of people addicted to diet colas who quit drinking soda altogether. I honestly think soda is addictive and I‘m happy not to be drinking it anymore.Comment 2Perhaps the slowdown has something more to do with the skyrocketing cost of soft drinks.Comment 3I LOVE diet drinks! Am I unhealthy? Who knows? I guarantee I have a better physique than most 43-year-old men.Comment4This is a silly and shallow piece。

EDA期末试卷及答案
EDA期末试卷及答案B.综合的输出是一个网表,包括逻辑门和它们之间的连接关系;C.综合的目的是将高层次的抽象设计转化为低层次的逻辑电路;D.综合只能在设计输入完成后进行,不能在设计实现和实际设计检验阶段进行。
一、填空题1.EDA技术的发展可分为MOS时代、CMOS时代和ASIC三个阶段。
2.EDA设计流程包括设计输入、设计实现、实际设计检验和下载编程四个步骤。
3.EDA设计输入主要包括图形输入、HDL文本输入和状态机输入。
4.时序仿真是在设计输入完成之后,选择具体器件并完成布局、布线之后进行的时序关系仿真,因此又称为功能仿真。
5.VHDL的数据对象包括变量、常量和信号,它们是用来存放各种类型数据的。
6.设计结束后必须进行仿真,以检查设计文件的正确性。
7.EDA方式设计实现的电路设计文件最终可以编程下载到FPGA和CPLD芯片中,完成硬件设计和验证。
8.MAX+PLUS的文本文件类型是“.vhd”。
9.在PC上利用VHDL进行项目设计时,不允许在根目录下进行,必须在根目录为设计建立一个工程目录(即文件夹)。
10.VHDL源程序的文件名应与实体名相同,否则无法通过编译。
二、选择题:11.在EDA工具中,能完成在目标系统器件上布局布线软件称为“适配器”。
12.执行MAX+PLUSⅡ的“TimingAnalyzer”命令可以精确分析设计电路输入与输出波形间的延时量。
13.VHDL常用的库是“XXX”。
14.“PROCESS语句”既是并行语句又是串行语句。
15.在VHDL中,用语句“clock’EVENT AND clock=’0’”表示clock的下降沿。
16.IP核在EDA技术和开发中具有十分重要的地位;提供用VHDL等硬件描述语言描述的功能块,但不涉及实现该功能块的具体电路的IP核为“胖IP”。
17.综合是EDA设计流程的关键步骤,在下面对综合的描述中,“综合只能在设计输入完成后进行,不能在设计实现和实际设计检验阶段进行”是错误的。
