wilderness.Search and rescue efforts can involve 20 or more people.But a new “smart” drone(無人機(jī)) can follow hiking trails(小路) without a pilots assistance.This could allow rescuers to search more efficiently.Scientists outfitted a craft with a single camera.As the drones “eye”,the camera pointed forwards.But having an eye wasnt enough.The drone also needed a “brain” to understand what it was seeing.And that brain would have to recognize what constitutes a trail.Camera images,however,can be very difficult for a puter to interpret,study leader Alessandro Giusti notes.So he and his team used photos of forest trails to train their drones neural network(神經(jīng)網(wǎng)絡(luò)).They attached three GoPro cameras to a single headband.One camera pointed straight forward.The other two were directed 30 degrees to the right and left of the centre.A hiker put the package on and then hit the trails in a forested part of Switzerland.Over several weeks,the cameras recorded a total of 8 hours of video covering 7 kilometres of trails.The researchers then divided the video into individual still images to train the neural network.The network learned to identify what a trail looked like.The team then tested the program with unused images from the video.The puter did a slightly better job than the people had in correctly classifying the images.This meant the drone was ready to navigate the real world on its own.Giusti and his team took their now “smart” device to a forest with trails that had not been used in the drones training.It flew along the path,constantly adjusting its direction based on the images ing in through its camera.The drone didnt perform as well in real-life as it did in the lab,Giusti admits.Thats because the drones camera took lower-quality images than the cameras that had been used to train it.As a result,the images being taken by the drone looked different,he explains.This confused its neural network.“Its an exciting use for neural networks,” says Christopher Rasmussen,a puter-vision scientist who was not involved with the study.“However,the problems faced in the experiments show that there are still some important issues to be worked out.”1.The “smart” drone has been created in order to help .A.find travelers who get lostB.ensure the safety of travelersC.deliver necessities to travelersD.show travelers the way to a place2.While being tested to classify the images in the lab,the puter .A.did as well as the peopleB.did a lot better than the peopleC.did much worse than the peopleD.did a little better than the people3.Why didnt the drone perform well in the forest?A.The light in the forest was very poor.B.The trees or bushes covered the trails.C.The drone couldnt fly very low there.D.The pictures taken were of poor quality.4.What is Christopher Rasmussens attitude towards the results of the experiments?A.Critical.B.Doubtful.C.Objective.D.Optimistic.B(2016石家莊調(diào)研檢測)Shopping centres,stadiums and universities may soon have a new tool to help fight crime.A California pany called Knightscope says its robots can predict and prevent crime.Knightscope says the goal is to reduce crime by half in areas the robots guard.William Santana Li is the chief executive officer of Knightscope.He says,“These robot security guards will change the world.Our planet has seven billion people on it.Its going to quickly get to nine billion people.The security equipment that we have globally is just not going to develop that fast.The panys Autonomous Data Machines can bee the eyes and ears of law enforcement (執(zhí)行).”“You want it to be machines plus humans.Let the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work,so its always working all together.”The machines are one and a half meters tall and weigh 136 kilograms.They do not carry weapons but they have day-and-night time video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.Some people may bee concerned about their privacy,especially in connection with the video recordings.Some people may worry that such recordings will appear on the Internet.Eugene Volokh,a law professor at the University of California,says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.William Santana Li says there is a long waiting list for the robots in the US.Workers in the pany are working overtime to meet the demands of the market.At least 25 other countries are also interested in these robotic security guards.5.What can this new tool do for humans?A.Make strategic decisions.B.Keep watching day and night.C.Carry heavy weapons.D.Stop crime autonomously.6.Why are people worried?A.Their privacy may be let out.B.The robots are very expensive.C.Robots will replace humans.D.They will be out of work soon.7.Which of the following can be the best title of the text?A.Robots Are Being More PopularB.Robots Contribute a Lot to the WorldC.Robots Are in Great Demand NowD.Security Robots Could Help Cut CrimeCFrom young kids to fitness lovers，to those looking for a laugh，or to families

prehensive statement that indicates health and wealth are linked to each other?People nowadays think the statement means when a person is healthy,he is capable of producing wealth.2 As a result,he/she wont be able to earn ine for an independent living.This explanation is partially true but the deep meaning of this claim can be understood by the words of the great ancient Roman poet Virgil:“The greatest wealth is health.”What Mr.Virgil tried to show is that the greatest wealth is health,not money or worldly items.There is nothing more valuable in life than having good health.Nowadays people are influenced by wealth improperly that they dont even bother about their health,the greatest wealth.3 A person with poor health is unable to enjoy the pleasures of life.Therefore,we should keep our health in the best way.4 For example,spending time in a natural environment and drinking enough water.Physical exercise is also necessary as it keeps a person smart and healthy.Eating a balanced diet keeps people away from different illnesses and diseases.It is said that:“Early to bed and early to rise,makes a man healthy,wealthy and wise.”Abandon unhealthy habits because they harm internal parts of our body.5 One should always remember,living a healthy life can be the greatest gift of life.A.Some people are so poor,and all they have is money.B.It refers to the abundance of money and worldly items.C.A simple preference that means health is superior to wealth?D.They dont realize that without health there is no real happiness.E.On the contrary,if one is not healthy,he/she cannot work productively.F.Always be optimistic and cheerful because:“Laughter is the best medicine.”G.There are lots of methods and practices through which a person can stay healthy.書面表達(dá)(2016鄭州第二次質(zhì)量預(yù)測)假設(shè)你校學(xué)生會(huì)定于4月10日組織一次高三學(xué)生的登山活動(dòng),請(qǐng)根據(jù)下面表格內(nèi)容,以學(xué)生會(huì)的名義用英語寫一則通知,歡迎同學(xué)們積極參加。目的鍛煉身體,放松心情地點(diǎn)邙山內(nèi)容與要求1.早上7:20在校門口乘公交車出發(fā),下午7:00返回;2.上午登山,中午在山頂野餐,下午分組自由活動(dòng);3.拍照、記錄,之后參加校攝影展或征文比賽。溫馨提示1.自帶午餐和飲用水;2.4月5日前到學(xué)生會(huì)報(bào)名。注意:1.詞數(shù)100左右;2.可以適當(dāng)增加細(xì)節(jié),以使行文連貫;3.通知的格式已為你寫好,不計(jì)入總詞數(shù)。參考詞匯:邙山Mangshan
