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 de signed 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。

Unit 2 RobotsⅠ.阅读理解It is not only praise or punishment that determines a child's level of confidence.There are some other important ways we shape our kids—particularly by giving instructions and commands in a negative or positive choice of words.For example，we can say to a child “Don't run into traffic！” or “Stay on the footpath close to me.” In using the latter，you will be helping your kids to think and act positively，and to feel competent in a wide range of situations，because they know what to do，and aren't scaring themselves about what not to do.Why does such a small thing make a difference？It is all in the way the human mind works.What we think，we automatically rehearse (预演)．For example，if someone offered you a million dollars not to think of a blue monkey for two minutes，you wouldn't be able to do it.When a child is told “Don't fall off the tree，” he will think of two things: “don't” and “fall off the tree”．That is，he will automatically create the picture of falling off the tree in his mind.A child who is vividly imagining falling off the tree is much more likely to fall off.So it is far better to use “Hold on to the tree carefully.”Clear and positive instructions help kids to understand the right way to do things.Kids do not always know how to be safe，or how to react to the warning of the danger in negative words.So parents should make their commands positive.“Sam，hold on firm to the side of the boat.” is much more useful than “Don't you dare to fall out of the boat？” or worse still “How do you think I'll feel if you drown？” The changes are small but the difference is obvious.Children learn how to guide and organize themselves from the way we guide them with our words，so it pays to be positive.1．Positive choice of words helps kids to__________.A．do things carefullyB．build up their confidenceC．improve their imaginationD．learn in different situations2．What can we infer from Paragraph 2?A．A child will act on what is instructed.B．One can't help imagining what is heard.C．A child will fall off the tree when told not to.D．One won't think of a blue monkey when given money.3．Which of the following commands helps kids to be safe?A．Fasten your seat belt.B．Don't play by the lake.C．How do you think I'll feel if you get hurt?D．Don't you dare to walk through the red light?4．The main idea of the passage is that__________.A．praise makes kids confidentB．right instructions keep kids safeC．clear commands make kids differentD．choice of words can make a difference答案：[解题导语]本文主要论证了积极正面的话语更能有效地告诉孩子应该做什么，从而培养孩子的自信。

Unit 2 RobotsⅠ.阅读理解AEach 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(无人机) can follow hiking trails(小路) without a pilot’s assistance.This could allo w 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 recognize what constitutes a trail.Camera images,however,can be very difficult for a computerto interpret,study leader Alessandro Giusti notes.So he and his team used photos of 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 of the centre.A hike r 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 kilometre s 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 computer 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 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 it did in the lab,Giusti admits.That’s because the d rone’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 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 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 computer .A.did as well as the peopleB.did a lot better than

Knightscope.He says,“These robot security guards will change the world.Our planet has seven billion people on it.It’s going to quickly get t o nine billion people.The security equipment that we have globally is just not going to develop that fast.The company’s Autonomous Data Machines can become the eye s and ears of law enforcement (执行).”“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 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.S ome people may become 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 theUS.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 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 Becoming More PopularB.Robots Contribute a Lot to

Unit 2 Robots(60分钟81分)Part A一、阅读理解(共8小题;每一小题2分,总分为16分)AMost people agree that honesty is a good thing.But does Mother Nature agree?Animals can’t talk,but can they lie in other ways?Can they lie with their bodies and behaviors?Animal experts may not call it lying,but they do agree that many animals,from birds to chimpanzees,behave dishonestly to fool other animals.Why?Dishonesty often helps them survive.Many kinds of birds are very successful at fooling other animals.For example,a bird called the plover sometimes pretends to be hurt in order to protect its young.When a predator(猎食动物)gets close to its nest,the plover leads the predator away from the nest.How?It pretends to have a broken wing.The predator follows the “hurt〞 adult,leaving the baby birds safe in the nest.Another kind of bird,the scrub jay,buries its food so it always has something to eat.Scrub jays are also thieves.They watch where others bury their food and steal it.But clever scrub jays seem to know when a thief is watching them.So they go back later,unbury the food,and bury it again somewhere else.Birds called cuckoos have found a way to have babies without doing much work.How?They don’t make nests.Instead,they get into other birds’ nests secretly.Then they lay their eggs and fly away.When the baby birds come out,their adoptive parents feed them.Chimpanzees,or chimps,can also be sneaky.After a fight,the losing chimp will give its hand to the other.When the winning chimp puts out its hand,too,the chimps are friendly again.But an animal expert once saw a losing chimp take the winner’s hand and start fighting again.Chimps are sneaky in other ways,too.When chimps find food that they love,such as bananas,it is natural for them to cry out.Then other chimps come running.But some clever chimps learn to cry very softly when they find food.That way,other chimps don’t hear them,and they don’t need to share their food.As is mentioned above,animals behave dishonestly for survival.Is it OK to lie for us human?(2015·福建永安质检)1.The writer uses the three questions at the beginning of the passage to .A.ask the readers to answer the questionsB.draw the readers’ attention to the topicC.seek answers to the questionsD.show he is at a loss about the questions2.Which of the following is not an example of animal’s dishonest behaviors?A.The plover pretended to have a broken wing to protect its baby birds.B.A scrub jay dug out its buried food and reburied it somewhere else.C.The adoptive parents feed their baby birds of cuckoos.D.A losing chimp starts fi ghting again after taking the winner’s hand.3.The underlined word “sneaky〞 in Paragraph 5 most probably means .A.selfishB.friendlyC.entertainingD.dishonest4.What is the common reaction of most chimps when they find their favorite food?A.They let out a loud cry.B.They cry in a very low voice.C.They hide their food immediately.D.They share their food with other chimps.【文章大意】本文是说明文。
