“smart”　drone(无人机) can follow hiking trails(小路) without a pilot’s assistance.This could allow rescuers to search 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 recognizewhat constitutes a trail.Camera images,however,can be very difficult for a computer to interpret,study leader Alessandro Giusti notes.So he and his team used photosof forest trails to train their drone’s neural network(神经网络).They attached three GoPro cameras to a single headband.One camera pointedstraight forward.The other two were directed 30 degrees to the right and left ofthe centre.A hiker put the package on and then hit the trails in a forested partof 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 trainthe 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 thedrone 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 drone’s training.It flew along the path,constantly adjusting its direction based on theimages coming in through its camera.The drone didn’t perform as well in real-life as it did in the lab,Giustiadmits.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 thedrone looked different,he explains.This confused its neural network.“It’s an exciting use for neural networks,” says Christopher Rasmussen,a computer-vision scientist who was not involved with the

The products displayedat the entrance? Or the soft background music?But have you ever notice the smell? Unless it is bad, the answer is likely to be no. But while a shop’s scent may not be outstanding compared with sights and sounds, itis certainly there. And it is providing to be an increasing powerful tool in encouraging people to purchase.A brand store has become famous for its distinctive scent which floats through thefairly dark hall and out to the entrance, via scent machines. A smell may be attractive but it may not just be used for freshening air. One sports goods company once reported that when it first introduced scent into its stores, customers’　intension to purchase increased by 80 percent.When it comes to the best shopping streets in Pairs, scent is just as important toa brand’s success as the quality of its window displays and goods on sale. That ismainly because shopping is a very different experience to what it used to be.Now the rise of electronic commerce (e-commerce)has opened up famous brands to a wider audience. But while e-shops can use sights and sounds, only bricks-and-mortar shops(实体店)can offer a full experience from the minute customers step through the door tothe moment they leave. Another brand store seeks to be much m ore than a shop, but rather a destination. And scent is just one way to achieve this.Now, a famous store uses complex man-made smell to make sure that the soft scent ofbaby powder floats through the kid department, and coconut scent in the swimsuitsection.

Unit 2 Robots一、阅读理解Captain John Bunch loves to go fishing. In fact, Bunch loves fishing so much that he became a professional fishing guide decades ago and has remained one ever since. There is something, however, that Bunch loves even more. That is his country and the men and women who join the army to protect it. Ever since Bunch met a young soldier in 2005, who wanted to go on a fishing trip before he left the army, the Florida native has offered over 1 200 fishing trips to veterans(退伍军人), with all expenses paid.And Bunch’s efforts to give back to those who have served their nation go even much further. Inspired by that fishing trip 11 years ago, he founded Operation Open Arms, which has since helped nearly 3 400 US troops and given out more than $12 million in direct benefits with his charity.

If you want a little extra security against thieves stealing your bicycle, designer Dennis Siegel has designed a solution. The RFID Bikealarm is attached to the seat on a bicycle and gives off an alarm when it senses movement.“The RFID Bikealarm is meant to be a useful add-on to mechanical bicycle locks because it greatly extends the range of protection with only a few components, ” Siegel explains on his website. “It is low-cost, durable and easy to use. ”The Bikealarm was designed as part of Siegel’s Bachelor’s degree thesis at the University of the Arts Bremen in Germany. The device will scare off any would-be thief the moment he begins to steal the bicycle to which it is attached. It is able to continuously sense the environment to distinguish between specific events, for instance a passing tram/car and a serious theft.Siegel created a working model of an alarm that would sound when it sensed movement, but wasn’t initially sure how it would be best attached to a bicycle. “I decided to mount it to the rails of the seat because it allows for comfortable interaction and the position is less obvious as it looks like a small repair kit, ” he says.Siegel chose to use RFID technology rather than Bluetooth to keep the costs down. Siegel explains that the most difficult aspect of creating the alarm was to get the electronic circuit down to a small enough size.The device runs off a kind of battery that can be charged by USB within 2 hours and lasts for a few days with normal use. As the Bikealarm is only at development stage, Siegel hasn’t signed any agreements to put it on the market.【文章大意】文章介绍了一种新型的防止自行车被盗的报警装置。

Despite being used by 1.34 billion people each year，traveling on the Tube in London can actually be quite lonely.One citizen，however，is trying to change this.“You get on the Tube and it’s completely silent and it’s weird，” says Jonathan Dunne，who has started a worldwide dialogue after giving out badges(徽章) with the words “Tube chat？” last month，encouraging passengers in London to get talking to one another.“I handed out 500 badges during rush hour in a city of 8 million，expecting most of them to be thrown away，but after about 24 hours it completely snowballed，”he says.Dunne and his “Tube chat” campaign have since been reported by media across the world，seeing TV interviews in Sweden, Brazil and the U．K.，as well as countless website，newspaper and magazine appearances.Although Dunne says he’s received mostly positive feedback，not everyone agrees with his idea.Londoner Brian Wilson responded with a campaign of his own，handing out 500 badges with the words “Don’t even think about it” on them. Michael Robinson，24，a student from London，agrees.“Being on the Tube is the only peace and quiet some people get on their journeys to and from work.It doesn’t need to be spoiled by people coming up and chatting to you，” he says.“People assume that I just walk up and talk to strangers, which I don’t，but it’s been a great way to meet people you would never have normally spoken to，”Dunne says.So if you ever end up using public transport in the West, why not say hello to the person next to you？Just make sure to check for a badge first.【解题导语】每年乘坐伦敦地铁的乘客众多，可是人们仍然感到孤独；为此Jonathan Dunne发起了一个旨在鼓励乘客相互交谈的运动，此举引起了世界媒体的关注。

Unit 2 RobotsⅠ.阅读理解A(2017湖北孝感高中9月调研)A Japanese telecom company has released a robot that is said to have emotions. But rather than run it in fear, we’ve welcomed it into our homes: Pepper, the “emotional robot”, sold out within a minute of going on sale.Created by Aldebaran Robotics and Japanese mobile giant SoftBank, Pepper went on sale to the general public in Japan on June 20. “It is the first humanoid(类人的) robot designed to live with humans,” Aldebaran says on its website. Pepper costs about $1,600.And like all good mobile products, there’s a $120 per month data fee, as well as an $80 per month damage insurance fee. According to a news release, Pepper can pick up on human emotions and create its own using a “multi-layer neural(神经的) network.” Pepper’s touch sensors and cameras are said to influence its mood, which is displayed on the tablet-sized screen on its chest.Pepper will sigh when unhappy, and can go around your house recording your family’s daily activity. Aldebaran says Pepper can feel “joy, surprise, anger, doubt and sadness”, but it doesn’t say how strongly it can feel these emotions. What happens when Pepper is having a bad day? Will it, like many humans, become uncooperative? Will it ask for some time alone? What happens if it figures out that its purpose in life is just to engage in small talks? Thankfully, Pepper is only about four feet tall, with roller balls instead of legs, so if it is angry with and even turns on its owners, you’ll be safe if you can make it upstairs.Aldebaran sa ys in reality, they’re probably quite a few decades away from artificial intelligence that could generate real emotions. Aldebaran wasn’t immediately available for comment on when Pepper will be available outside of Japan, but additional sales are scheduled for July after the first 1,000 units sell out. SoftBank currently uses the robots in its stores as greeters, and it plans to offer Pepper to other stores in the future. Hopefully, “boredom” is not an emotion Pepper can feel.1.According to the author, Pepper .A.is very popular among customersB.can not only run but also show fearC.is going to be sold all over the worldD.can deal with many kinds of housework2.How much do you need to pay for Pepper’s data and damage insurance fee each year?A.80 dollars.B.120 dollars.C.1,440 dollars.D.2,400 dollars.3.Pepper’s height and roller balls are mentioned to .A.introduce its appearanceB.tell Pepper won’t get angryC.show that safety isn’t a big issueD.explain robots have strong emotions4.What can we infer from the last paragraph?A.Pepper cannot produce real emotions.B.Pepper can feel joy, surprise and boredom.C.Pepper will be sold in other countries next year.D.Pepper is being used as waiters in some restaurants.BYour house may have an effect on your figure.Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off.You can make your environment work for you instead of against you.Here are some ways to turn your home into part of your diet plan.Open the curtains and turn up the lights.Dark environments are more likely to encourage overeating,for people are often less self-conscious(难为情)when they’re in poorly lit places—and so more likely to eat lots of food.If your home doesn’t have enoug h window light,get more lamps and flood the place with brightness.Mind the colors.Research suggests warm colors fuel our appetites.In one study,people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room.Warm colors like yellow make food appear more appetizing,while cold colors make us feel less hungry.So when it’s time to repaint,go blue.Don’t forget the clock—or the radio.People who eat slowly tend to consume about 70 fewer calories(卡路里)per meal than those who rush through their meals.Begin keeping track of the time,and try to make dinner last at least 30 minutes.And while you’re at it,actually sit down to eat.If you need some help slowing down,turn on relaxing music.It makes you less likely to rush through a meal.Downsize the dishes.Big serving bowls and plates can easily make us fat.We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate.When we choose a large spoon over a smaller one,total intake(摄入)jumps by 14 percent.And we’ll pour about30 percent more liquid into a short,wide glass than a tall,skinny glass.5.The text is especially helpful for those who care about .A.their home comfortsB.their body shapeC.house buyingD.healthy diets6.A home environment in blue can help people .A.digest food betterB.reduce food intakeC.burn more caloriesD.regain their appetites7.What are people advised to do at mealtimes?A.Eat quickly.B.Play fast music.e smaller spoons.D.Turn down the lights.8.What can be a suitable title for the text?A.Is Your House Making You Fat?B.Ways of Serving DinnerC.Effects of Self-ConsciousnessD.Is Your Home Environment Relaxing?Ⅱ.语法填空(2018甘肃会宁一中高三第一次月考)阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。

It’s an annual argument. Do we or do we not go on holiday? My wife says no because we have no savings to save us. I say you only live once and we work hard and what’s the point if you can’t go on holiday. The joy of a recession (不景气) means no argument next year —we just won’t go.Since money is known to be one of the things most likely to bring a relationship to its knees, we should be grateful. For many families the recession means more than not booking a holiday. A YouGov survey of 2,000 people found 22% said they were arguing more with their partners because of concerns about money. A recent research shows arguments about money were especially damaging to couples.Kim Stephenson, an occupational psychologist, believes money may be different things to men and women. ＂People can say the same things about money but have different ideas of what it’s for, ＂ he explains. ＂They’ll say it’s to save, to spend, for security, for freedom, to show someone you love them.＂ He says men are more likely to see money as a way of buying status and of showing their parents that they’ve achieved something.＂The biggest problem is that couples assume each other know what’s going on with their finances, but they don’t. There seems to be more of a taboo (禁忌) about talking about money than about death. But you both need to know what you’re doing, who’s paying what into the joint account and how much you keep separately. In a healthy relationship, you don’t have to agree about money, but you have to talk ab out it.＂1. What does the author say about going on holiday in Paragraph 1?A. It will cost them too much money.B. Few people can afford it without working hard.C. It makes all the hard work worthwhile.D. It is the chief cause of family quarrels.2. According to the text, what does Kim Stephenson believe?A. Money is often a symbol of a person’s status.B. Money means a great deal to both men and women.C. Men and women spend money on different things.D. Men and women view money in different ways.3. The author suggests that couples should________.A. put their money together instead of keeping it separatelyB. discuss money matters to maintain a healthy relationshipC. make efforts to reach agreement on their family budgetsD. avoid arguing about money matters to remain romantic【文章大意】文章通过度假的问题引入话题，男人和女人对钱的看法是不一样的，夫妻应该就钱的问题多进行讨论，这样可以建立健康的关系。

课时作业 32Ⅰ.阅读理解(2019·陕西省榆林市第一中学高三检测)Robots come in many shapes and sizes, but scientists in Zurich, Switzerland, have developed one new robot called Pleurobot, which looks and acts just like a salamander (火蜥蜴)．To create the robot, scientists took hun dreds of X­rays of real salamanders. They studied the images of these animals to see which joints (关节) and muscles the animals use as they move. Then the scientists built the Pleurobot's skeleton to move just like the real thing. This makes the robot's movements incredibly lifelike.According to experts, salamanders were among the first animals to develop a skeleton and nervous system that allowed them to travel on land. “By studying the modern salamander, we have a time window to the ancestors of all vertebrates(脊椎动物), including humans，” Auke Ijspeert, the designer of the robot, told scholastic News Online.Both people and salamanders have a spinal cord (脊髓). An injury to the spinal cord can result in the inability to move. Now, there is no cure for paralysis (瘫痪). Ijspeert hopes that the Pleurobot can help change that. Because these studies could help researchers develop new ways to help people who have been paralyzed by spinal cord injuries.Scientists think that the Pleurobot could also be used for search­and­rescue tasks too dangerous for humans. Because the robot is low to the ground and has a wide range of motion, it could be used to get into dangerous places, like fallen buildings, to look for survivors. Thanks to its waterproof suit, the robotic salamander could even participate in underwater missions.Experts are now working on a smaller, sturdier (harder to break) model of the Pleurobot. They expect this one to be even better suited for getting into small spaces to do dangerous work.这篇文章主要讲了瑞士的科学家发明了一款新的机器人，这款机器人看起来有些像火蜥蜴。

Unit 2 Robots李仕才一、阅读理解Captain John Bunch loves to go fishing. In fact， Bunch loves fishing so much that he became a professional fishing guide decades ago and has remained one ever since. There is something, however， that Bunch loves even more。

That is his country and the men and women who join the army to protect it. Ever since Bunch met a young soldier in 2005, who wanted to go on a fishing trip before he left the army， the Florida native has offered over 1 200 fishing trips to veterans(退伍军人）, with all expenses paid。
