structuralambiguity例子Structural Ambiguity ExamplesIntroduction:Structural ambiguity refers to a linguistic phenomenon where a sentence or phrase can have multiple interpretations due to its ambiguous structure. In this article, we will explore several examples of structural ambiguity and discuss their implications in language and communication.1. The Flying Planes:Consider the sentence: "The flying planes are dangerous." This sentence can have two possible interpretations:- Interpration 1: The planes that are flying are dangerous.- Interpretation 2: The planes themselves are airborne and capable of flying, which poses a danger.This ambiguity arises due to the structural ambiguity of the phrase "The flying planes," which can be read as a noun phrase modifying "dangerous" or as a subject-verb combination.2. Visiting Relatives:In the sentence "Visiting relatives can be exhausting," there is ambiguity in the interpretation of "visiting relatives":- Interpretation 1: The act of visiting one's relatives can be exhausting.- Interpretation 2: The relatives who are visiting can be exhausting.The structure of the phrase "visiting relatives" allows for both a gerund interpretation (the activity of visiting) and a noun phrase interpretation (the relatives who are visiting).3. The Dog Bit Tim:Consider the sentence "The dog bit Tim." This sentence is structurally ambiguous and can be understood in two ways:- Interpretation 1: The dog bit a person named Tim.- Interpretation 2: A dog named Tim bit someone.The ambiguity arises from the lack of specificity in the sentence's structure, as it does not clarify whether "Tim" refers to the subject or object of the sentence.4. Time Flies Like an Arrow:The phrase "Time flies like an arrow" demonstrates structural ambiguity due to its use of the word "like":- Interpretation 1: Time passes quickly, similar to how an arrow travels swiftly.- Interpretation 2: Time enjoys an arrow in the same manner as an insect would enjoy a flower.This ambiguity arises from the different senses of "like" (as a comparative or as enjoyment) and how it interacts with the sentence structure.5. The Man Saw the Boy with Binoculars:In the sentence "The man saw the boy with binoculars," there are two possible interpretations:- Interpretation 1: The man used binoculars to see the boy.- Interpretation 2: The man saw the boy, who was holding binoculars.This ambiguity arises because the phrase "with binoculars" can either modify "the boy" or "saw," leading to different meanings depending on the interpretation.Conclusion:Structural ambiguity in language can lead to various interpretations, causing confusion and miscommunication. The examples provided highlight how sentence structure and ambiguous phrases can create multiple meanings. Understanding structural ambiguity is crucial for effective communication, as it allows us to recognize potential ambiguities and clarify our intended message. By being aware of these linguistic complexities, we can strive for clearer and more precise communication.。

有关于狼的英文谚语范文1:In many cultures, the wolf is a symbol of power, loyalty, and courage. There are also many famous English proverbs related to wolves. Let's take a look at some of them.1. "A wolf in sheep's clothing." This means someone who pretends to be harmless or friendly but is actually dangerous or deceitful. The phrase originates from a fable in which a wolf puts on a sheepskin to deceive a flock of sheep.2. "To throw someone to the wolves." This means to abandon someone to face a difficult or dangerous situation alone. The phrase comes from the way wolves and other predators hunt, often isolating one of their prey before attacking it.3. "Cry wolf." This means to call for help or attention when it is not really needed, thereby making it less likely that people will believe you when you really are in danger. The phrase comes from a fable in which a boy repeatedly cries "wolf" to trick the villagers into coming to his aid, but when a real wolf appears and he cries for help, no one believes him.4. "Wolf pack." This refers to a group of people (or animals) who work together in a coordinated and often ruthless manner, like a group of wolves hunting their prey.In conclusion, wolves are fascinating creatures that have inspired a variety of English proverbs and expressions. Whether you see themas symbols of strength and loyalty or as dangerous predators, their presence in our collective imagination is undeniable.要点分析:写作重点:介绍了有关于狼的英文谚语,并分别解释了它们的含义和来源。

危险英语短语Dangerous English PhrasesThe English language is a rich and diverse means of communication, with a vast array of words and expressions that can convey a wide range of emotions, ideas, and perspectives. However, within this linguistic tapestry, there are certain phrases that can be considered "dangerous" – words or combinations of words that, if used carelessly or without proper understanding, can have unintended and potentially harmful consequences.One such phrase that falls into this category is "I don't care." This seemingly innocuous statement can be interpreted in various ways, depending on the context and the tone in which it is delivered. In some instances, it may be a genuine expression of indifference or a lack of concern for a particular issue. However, when used in the context of a personal relationship or a sensitive situation, it can be perceived as a dismissive or hurtful response, potentially damaging the trust and connection between individuals.Another potentially dangerous phrase is "I'm just joking." While humor and lightheartedness can be valuable in building relationshipsand diffusing tense situations, the use of this phrase can sometimes be a way to mask hurtful or insensitive comments. It can be a means of deflecting responsibility for one's words and actions, and it can leave the recipient feeling invalidated or disrespected.The phrase "I'm sorry, but..." is another example of a dangerous English expression. The initial apology may seem sincere, but the addition of the word "but" often undermines the sentiment and can be interpreted as a way of shifting blame or justifying one's actions. This can be particularly problematic in situations where a genuine apology and accountability are necessary for healing and reconciliation.The use of the word "always" or "never" in certain contexts can also be considered a dangerous phrase. Statements like "You always do that" or "You never listen to me" can be perceived as absolutes that fail to acknowledge the nuances and complexities of human behavior and relationships. Such sweeping generalizations can lead to feelings of frustration, defensiveness, and a breakdown in communication.Another phrase that can be hazardous is "I was just being honest." While honesty is a valuable and admirable quality, it can sometimes be used as a cover for insensitive or hurtful comments. The use of this phrase can suggest that the speaker is more concerned with their own need to express their views than with the impact theirwords may have on the recipient.The phrase "I didn't mean it that way" is another example of a dangerous English expression. When used in response to a perceived offense or misunderstanding, it can come across as a dismissal of the other person's feelings and an attempt to shift the responsibility for the impact of one's words.Finally, the phrase "I'm not racist, but..." is a particularly problematic and dangerous expression. The use of this phrase often precedes a statement that is, in fact, racist or discriminatory in nature. It can be a way of attempting to legitimize or justify prejudiced views, while simultaneously denying or minimizing the harm they can cause.In conclusion, the English language is a powerful tool for communication, but it is also one that must be wielded with care and consideration. Phrases that may seem innocuous or even well-intentioned can, in fact, be dangerous when used without proper understanding or sensitivity. By being mindful of the potential impact of our words and choosing our language carefully, we can foster more meaningful and constructive dialogues, build stronger relationships, and contribute to a more inclusive and compassionate society.。

第三大题阅读理解选择题首字母AAccording to experts,the advantage of modified food is that it helps in preventing the occurrence of allergies and also has along shelf life.However,a major portion of the population is against the consumption of genetically modified food and is concerned about its disadvantages.If you are also confused about the consumption of genetically modified food,read through the pros and cons given below and decide for yourself.Advantages of Genetically Modified Foods●One of the most prominent advantages of genetically modified food is that it helps in controlling the occurrence of certain diseases.Certain foods cause allergy to people.Their genetic modification alters the DNA system of these foods,thereby making them non-allergic.●Another major advantage of such type of foods is that they grow faster than their traditionally grown counterparts.As a result,there is greater productivity and more food.●A person need not bother about any additional costs,such as buying chemicals and pesticides,when it comes to genetically engineered food.The food is naturally pest-resistant.●Farming these foods can be a great way to fight world hunger.Since these crops grow faster or more effectively,increased production would help countries wherein crops may not normally prosper because of less than desirable environmental conditions.●The increased shelf life of these food products helps in reducing the quantity of rotten food.Disadvantages of Genetically Modified Foods●The biggest disadvantage of genetically modified food is that they have harmful effects on the human body.The consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics.●Chances of developing cancer are high in people who regularly consume engineered food.●Since it is an unnatural way of producing foods,there is an increased health hazard such as allergens,transfer of antibiotic resistance markers and unknown effects.●Since the production of engineered food involves infusing animal genes in the crops and tampering with nature,it might not be good for consumption in the long run.特别提醒:本题共5个小题,需要拉动答题框右边的滚动条使5个试题显示出来做答!![单选题]◆How does

about breast enlargement in Thailand.Anyone who is not sure about breast enlargement should read this story first.Firstly,I was amazed at the level of care I received at the Thailand private hospital.It was like being in a luxury hotel.The nursing staffs were also better than those who I have ever met in all my years in America.Not only were they professional,but kinder and more patient than Western nurses.The hospital food was excellent,so I was able to choose from a large and varied Menu.In my private room,there was cable T.V.,a fridge,a phone,and impressive views of Bangkok(曼谷).My Translator was able to communicate with me,and the plastic surgeons arranged the whole operation without me lifting a finger.The operation cost me a third of the price of the U.K.With the low cost of the air tickets and a holiday,it worked out at about half UK’s price,because the cost in Thailand is so cheap.Combining a plastic surgery with a holiday in an amazing place is an unforgettable experience.From the moment I arrived in Bangkok airport,I felt relaxed and welcomed by the Plastic Surgery&Holiday team,it made me feel that I had friends here

you think3D printing is only good for making flimsy paperweights.then you’re pretty much right.However.a group of audacious Dutch architects have already begun3D printing an entire canal house in Amsterdam.Is the first3D printed house a gimmick?Definitely!Is it an experiment that pushes the possibilities for3D printing technology and architecture?Maybel3D Print Canal House is the brainchild of DUS Architects.“KamerMaker’.Dutch for’room maker”,is their giant printer built inside a shipping container.Just a few weeks ago,KamerMaker began printing plastic furniture and walls at an empty canal-side lot in northern Amsterdam.Smaller versions of the unusual honeycomb walls have been tested on normal desktop printers,and everyone just needed to scale it up.Well,if only it were that easy.The printer did not always manage to spread the plastic evenly,making some of the ribs of the honeycomb structure of the block uneven.reported ARN(Australian Radio Network,to the surprise of no one who has used a 3D printer.But the architects remain optimistic.The first few printed blocks are meant to be test pieces as they improve the process.It takes about a week to print a3-meter high block right now.The project’s leader hopes to eventually get that down to two hours and finish the first of12rooms in a year.and the entire house in less than3years. Ultimately,3D Print Canal House is an architectural research project,one that is very much being conducted in the public eye:you can actually buy tickets to visit the construction site for2、50Euros.The top floors will become more omate.for example.as newer techniques are incorporated.They’ll explore the possibilities of3D printing.like the honeycomb walls or an entire room recycled.redesigned,and built anew.Nobody’s going to move into a3D printed house soon,but,if any on ever does.something might be learned from this experiment by the canal.特别提醒:本题共5个小题,需要拉动答题框右边的滚动条使5个试题显示出来做答!![单选题]◆What have the Dutch architects begun to use the3D printer to do according to the passage?A.To make heavy paperweights.B.To print the unusual

out the horrible black smoke.What are you going to do about it?In our modem days,too many people depend on their cars to get to work or to drop off their children to school.However,is it safe to have an increasing number of cars on our roads?Research shows that cars create serious pollution.Exhaust from all combustion engines produce harmful effects on the health of both car users and all innocent walkers.Cities have become islands of toxic chemicals from the unrestrained use of vehicles burning fossil fuels.The harmful health effects of car exhaust are pervasive and difficult to measure.For example,people with asthma would suffer with attacks due to the pollution.The world wild life also suffers from the cars’toxic emissions.No matter how much manufacturers try to make cars environmentally friendly it will damage our earth in one way or another.Additionally cars are too dangerous for our community.Careless drivers put themselves and others in danger.Cars are critical to walkers especially to children if the driver is not looking on the road or somehow distracted Have you known someone whose toes or feet have been run over by cars while crossing the street?Lastly.cars create social problems,which could lead to poor health.A few drivers suffer“Road Rage”and put themselves.loved ones and others in a threatening situation.Some cars create disturbing noises,which disturbs people living near highways,freeways,etc.not to get enough sleep.People depend on their cars so much that they forgot to exercise their bodies and end up being obese or having a heart problem.As a result of the excessive number of cars on our roads,everyone’s life is in danger.In order to create an environmentally friendly and safe world,it is necessary for each country to limit the permits in number to control regional air pollution.Second,car manufacturers should try to improve the efficiency of vehicles,such as finding solutions to emissions of combustion engines,developing new power sources such as new fuels,natural gas.Third,try to improve efficiency of traffic by setting up dedicated bus lanes and giving priority to car-pools and vehicles with3or more passengers.Besides,traffic can be scheduled;for example,commercial traffic atnight;large companies can shift working hours and decentralize administrative operations.特别提醒:本题共5个小题,需要拉动答题框右边的滚动条使5个试题显示出来做答!![单选题]◆Exhaust from cars is________.A.harmlessB.pollutiveC.not serious[答案]B[单选题]◆In the author’s view,it is________to make cars be friendly to

proper operation to cut off that bad foot.Months after the healing process,engineers at Nova copy Company produced a3D printed model that would be used to create a prosthetic(修复的)foot for the duck.Considering that ABS plastics were not flexible enough for this type of exercise,the Nova copy company made a three-dimension ally modeled foot made of silicone,with the hope to create a permanent prosthesis(假肢)for the duck.It took just13hours to produce.This3D prosthesis demonstrated the3D technologies can be used not only for human application,but also in foreign subjects such as

by robotics company Shanghai PT Info,the brightly colored robot,which costs 5,000yuan($790),was launched on Aug14to help entertain and monitor elderly people.In Shanghai last year,the number of registered residents at least60years old was4million.That was nearly30 percent of the population.By2018,the figure is projected to rise to5million.With many living alone,robots such as Roby Mini can help playa crucial role in caring for the elderly.“It will change the way people interact with digital products,”Hong says.Founded in May,Shanghai PT Info had already done the groundwork.In fact,the research team spent three years developing the speech recognition system before the firm was officially launched.With360-degree wheels hidden under its body,Roby Mini can follow a person through face recognition and strike up a conversation,tell jokes or provide information.The robot also works as a computer terminal,supplying weather information,ordering groceries online and even booking taxis.Roby Mini can be connected to other gadgets as well,such as smart wristbands or magnetic devices on doors.Roby Mini can also connect an elderly owner to a doctor through its high-definition screen.Already Shanghai PT Info is talking to three community hospitals in Shanghai’s Min hang district.Since the robot is linked to the Internet,it can support long-distance audio and video calls.Mass production started this month and Shanghai PT Info plans to manufacture200,000units this year.But the future is not easy for Shanghai PT Info.Earlier this year,Flying wings Intelligent Robot Technology(Shanghai)introduced a machine with sensors that will ring an alarm when an elderly person falls down.Tianjin Shangjiu Sheng yuan Technology Group also developed a robot for seniors in2014.Owners can turn on the lights and air-conditioning units by pressing buttons on the machine.It can also remind elderly owners to take pills,and inform them of hospital checkups and family

we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possibly months.It should be remembered that just as a building is no stronger than its foundation,our long-term goals cannot amount to very much without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed.The intermediate goals build on the foundation of the short-term goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed.As you complete each step,you will enforce the belief in your ability to grow and succeed.And as your list of completion dates grows,your motivation and desire will increase.Long-term goals may be related to our dreams of the future.They might cover five years or more.Life is not a static thing.We should never allow a long-term goal to limit us or our course of action.特别提醒:本题共5个小题,需要拉动答题框右边的滚动条使5个试题显示出来做答!![单选题]◆Short-term goals are the ones

costly.So researchers asked what would happen if the heat created by the servers could be captured and used?Data centers of large Internet companies such as Google and Microsoft have thousands of computer servers.As these servers process information,they create large amounts of heat,so they need huge cooling systems,These systems send the heat into the air.The Dutch company Nerdalize thinks paying for electrieity to operate the servers and then paying again to cool them is a waste of energy.So it developed a device called the e-Radiator.It is a computer server that also works as a heating source.Boaz Leupe is the chief executive officer of Nerdalize,He says the e-Radiator saves money because companies don’t have to pay to cool their servers.“The kilowatt(千瓦)hour you are using is used twice-once to heat the home and once to compute the client’s task without the cooling overhead.”He says five homeowners in the Netherlands are testing the heating device in their homes.“We reimburse the electricity the server uses,and that we can do because of the computer clients on the other side,and,in that way,homeowners actually get heating for free,and computer users don’t have to pay for the overhead of the data center.”Jan Visser is one of the participants in the year-long experiment.He says the amount of heat produced by the e-Radiator into room depends on the work being done by the computer server.He says it can not be used as theprimary source of heat.But he is ready to try it.He says if it provides enough warmth,he will be able to use his home’s heating system less,which will save him money.Nerdalize says e-Radiators create heat temperatures of up to55℃.It says the devices could save users up to$440in heating costs a year.特别提醒:本题共5个小题,需要拉动答题框右边的滚动条使5个试题显示出来做答!![单选题]◆Why did researchers ask what would happen if the heat created by the servers could be captured and used?A.Because computers can get very hot.puter

HomesC.Hot Computers Could Be Used for Free[答案]AWHY BUILD A SPACE ELEVATOR?The space elevator will reduce the cost of getting from Earth to space.It will also allow us to take very large payloads into space very easily,very safely.Because of that,we can build cities on the moon.We can build space stations.We can build large solar arrays in space to collect energy from the sun and beam it down to Earth.WHY NOT JUST USE ROCKETS INSTEAD?Rockets are very expensive.The shuttle costs S10,000a pound to put a payload into low-Earth orbit,and if you want to go to the moon or Mars,it’s hundreds of thousands of dollars per pound or more.Rockets are also very limited in the amount of payload they can carry.and they’re risky.With a space elevator,the cost is a fraction of that-it may go down to100th or1,000th of current costs-and there are no rocket engines that might explode.WHAT WOULD IT BE LIKE TO RIDE THE ELEVATOR?You’d go to an ocean platform,you’d climb into a module,and you’d feel it start moving.You’d see the Earth fall away.In just a half hour or so,you’d pass up through the clouds,and you’d start to see the curve of the horizon.Another half an hour to an hour later,you’d basically be in space.You’d see stars,even in the middle of the day.Eventually you’d be weightless.It’d be a very smooth ride:there wouldn’t be any shaking.ARE THERE POTENTIAL DRAWBACKS TO OPENING SPACE THIS WAY?Everything we do has the potential for creating some bad.If we mine an asteroid,the asteroid’s going to look ugly.just like a mine here.But I think the benefits of opening up space far outweigh the damage that we can see-benefits in terms of gaining energy from space to replace oil.additional capabilities in telecommunications. manufacturing in space.additional real estate and exploration.特别提醒:本题共5个小题,需要拉动答题框右边的滚动条使5个试题显示出来做答!![单选题]◆If a space elevator is built,what can’t be built by us?A.Cities on the moon.B.Space stations.C.Skyscrapers in space.D.Expressways in

alone?How would you like to climb into a robotic car and eat breakfast with the kids while you’re all driven to school and work?These scenarios may sound like science fiction,but experts say they’re a lot closer to becoming reality than you probably think.Brown University roboticist Chad Jenkins expects a near-term robot revolution that will echo the computing revolution of recent decades.And he says it will be driven by enabling robots to learn more like humans do-by watching others demonstrate behaviors and by asking questions.。

危险与机遇并存的英语"Danger and opportunity coexist" is a common saying in English. This phrase highlights how a situation that may seem dangerous or risky can also present opportunities for growth and advancement. It offers encouragement to individuals to take calculated risks and embrace challenges, even in the face of adversity.In the business world, for example, market volatility and financial uncertainties can pose potential dangers to a company's success. However, these same conditions can also create opportunities for businesses to innovate, adapt, and pivot in response to changing market demands and emerging trends.Similarly, in personal development, challenges and obstacles can be viewed as opportunities for growth and self-improvement. The difficulties that one experiences in life can result in greater strength, resilience, and wisdom, helping individuals to navigate future challenges with greater ease and confidence.Overall, the phrase "danger and opportunity coexist" reminds us that every challenge comes with the potential for growth and advancement. By embracing risk and uncertainty, we can seize opportunities that might not otherwise be available and experience personal and professional success.。
