6、illed 9. themselves 10. at Ⅰ.閱讀理解 A Each year,hikers and mountain bikers get lost or injured in the wilderness.Search and rescue efforts can involve 20 or more people.But a new “smart” drone(無(wú)人機(jī)) can follow hiking trails(小路) without a pilot’s assistance.This could allow rescuers to search

7、 more efficiently. Scientists outfitted a craft with a single camera.As the drone’s “eye”,the camera pointed forwards.But having an eye wasn’t 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,howeve

8、r,can be very difficult for a computer to interpret,study leader Alessandro Giusti notes.So he and his team used photos of forest trails to train their drone’s 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 directe

9、d 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 ima

10、ges 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 computer did a slightly better job than the people had in correctly classifying the images.This meant the drone was ready to navigate the re

11、al 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 drone’s training.It flew along the path,constantly adjusting its direction based on the images coming in through its camera. The drone didn’t perform as well in real-life as i

12、t did in the lab,Giusti admits.That’s because the drone’s 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. “It’s an exciting use for neural networks,” says

13、Christopher Rasmussen,a computer-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 lost B.ensure

18、have globally is just not going to develop that fast.The company’s Autonomous Data Machines can become 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 w

19、ork,so it’s 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 become conce

20、rned 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 st

21、ate 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 company 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 t

When it comes to the best shopping streets in Pairs, scent is just as important to a brand’s success as the quality of its window displays and goods on sale.
