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 already.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]◆Where did the author have her breast-enlargement operation?A.In Thailand.B.In America.C.In U.K.[答案]A[单选题]◆Was the author satisfied with the nursing

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 animals and other medical treatments.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]◆Where was the baby duck hatched out?A.In a college biology lab.B.In a back yard.C.In Nova copy Company.[答案]A[单选题]◆What

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 birthdays.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！！◆Roby Mini is the name of_________.A.a robotics companyB.a robotC.a senior citizen living alone[答案]B[单选题]◆Roby Mini is designed to_________.A.help look

ShanghaiC.Robot Gives Help to Older People[答案]C首字母TThere are three kinds of goals:short-term,medium-range and long-term goals.Short-term goals are those that usually deal with current activities,which 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 that________.A.motivate you over the long haulB.keep you engaged on a daily basisC.might be measured for many years[答案]B[单选题]◆The medium-range goals are built upon________.A.belief and successB.the

discouraged.C.Life is a static thing,thus never allowing a long-term goal to limit us.[答案]A首字母WWhen computer servers operate a complex program,they can get very hot.Cooling the servers can be 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.。
