1、1、When Gitanjali Rao shared how she likes “finding solutions to real problems”, it was hard to imagine this dynamic 11-year-old girl could settle a problem that has escaped scientists for years.In just three months, Rao came up with a device(装置)that can replace the costly and lengthy tests currently
2、 used to reliably determine lead(铅) levels in our fresh water. Inspired by the current litigation (诉讼)in Flint, Michigan, a case of water pollution from 2014 to 2015, Rao designed a new testing system that resulted in her being named Americas Top Young Scientist for 2017.Rao had been following the w
3、ater problem for about two years. She was amazed by the number of people affected by lead pollution in water and wanted to do something to change this. Gitanjali spent months trying to convince local high schools and colleges to give her lab time to continue her experiment. At home, Gitanjali worked
4、 on her project in the “science room” she asked her parents to create for her. Rao has created a device that uses three parts: a cartridge, a Bluetooth reader and an app. To put it simply, the cartridge contains carbon nanotubes(纳米管) that react to lead. This reaction is then registered by the Blueto
5、oth reader, which sends a signal to a mobile app that can tell you immediately if your water is safe to drink.Rao appropriately named the device Tethys after the Greek goddess of fresh water, and is hoping to make a little improvement to get the device on the market. While we may not be aware of any
6、 lead pollution present in our aging pipelines, lead poisoning can cause delays in physical and mental development. With Rao believing that the “purpose of science is to make a difference”, her incredible invention could make a difference to millions of people in the United States.1.What do we know

11、y decreases.Thats the conclusion of a study that put roughly 400 college students to task solving challenging word puzzles. When they were about halfway through, the researchers allowed most of the students to take a break either using their phones, using a computer or reading a print circular. Othe
12、r students were told to just keep on working without any sort of break.The results showed that the students who took a break with their phones were the worst performers of all the groups. They took 19% longer to finish the tasks and they solved 22% fewer word-problems than all the other groups combi
13、ned. In fact, the cell-phone groups efficiency and processing speed was about the same as the group that took no break. The reason offered by the researchers isnt merely because digital devices are inherently engaging(迷人的), but becauseour smartphones are attention gates into so many other attention-
14、catching areas, each pulling our mental energy in different directions.This research stresses that we ignored the energy reduction from using our smartphones, and that we were over-confident about what our brains can handle.We also overlooked the emotional connection wed developed with our phones.It

But recent experiments are proving that autonomous vehicles also have the potential to improve the quality of life for millions of Americans underserved by traditional modes of transportation, such as the elderly and disabled, so long as lawmakers make smart policies tha
20、t pave the way for innovation.A retirement community in San Jose, Calif. , which has been transformed by a small fleet of driverless taxis, shows the potential of self-driving cars to transform peoples lives. Built by a tech start-up called Voyage, the modified Ford Fusions are currently limited to
21、a two-mile road, but residents are already having the benefits of these autonomous vehicles, which allow them to participate in social activities they would otherwise be unable to enjoy simply because they could not get to them.When the trial run finally expands to 15 miles of road, these residentsw
22、hose average age is 76will also have a convenient and reliable new way to appointments. As these cars continue to serve residents there, it is easy to understand why California is moving to simplify regulations for the industry.In Michigan, forward-thinking policies have the potential to unlock othe
23、r hidden benefits of autonomous vehicles, especially for those with physical disabilities. The Michigan Disability Rights Coalition has strongly advocated for the development of this technology, saying that it could give people with disabilities greater opportunities in the workforce and enable them
24、 to lead more fulfilling, independent lives.Many recognize that autonomous vehicles will be the future of transportation, but it is too often overlooked that this future cannot arrive fast enough for millions of Americans who are forced to depend on others for day-to-day travel. The policymakers sho

28、overlooked despite technology advances.4、 A 27-year-old inventor, Joco Paulo Lammoglia, has come up with a new device named the AIRE mask, which is capable of converting the wind energy provided by the wearers breath into electrical energy. This means breathing has become a source of renewable energ
29、y. The inspiration for the invention came from his watching children blowing on pinwheels(玩具风车). The device is worn like a mask equipped with tiny wind turbines(涡轮机) and it can work its magic even while people are sleeping, jogging or hanging around,since energy is created from ones breath. The prin
30、ciple of this AIRE mask is simple. The invention uses the wind flow created by breathing and changes it into energy that can charge mobile phones and iPods. Simply put this mask connected to your mobile phone on your face. The rest takes place naturally through your breath that provides power to run
31、 turbines which produce electricity. Lammoglia explained how useful he hopes the AIRE will become. He said, I hope to bring the concept into production and reduce the carbon footprint. It can be used indoors or outdoors, while youre sleeping, walking,running or even reading books. Apart from saving
32、energy and contributing to the environmental protection, it also encourages thepractice of physical exercise. This is an entirely all-time renewable energy source. Its energy is available 24 hours a day, seven days a week. Lammoglia explained why he thought the AIRE was so useful, saying, Though man
33、y of our modern devices offer benefits, they tend to consume a high amount of electrical energy. This may cause environmental problems, especially if the energy used by these devices is obtained from non-renewable energy sources. The AIRE mask will be the future cheaper energy source of charging mob
34、ile phones. It would save energy and allow people to never have to worry about their phone dying unless they stop breathing.1.The underlined word “converting” (Para. 1 ) is closest in meaning to _.A.chargingB.convincingC.exchangingD.transforming2.Lammoglia would most probably agree that the AIRE mas

It harvests all the person knows your password. Whats more, this device needs no batteries. It harvests all the energy it
38、 needs from the action of your typing. Besides, the keyboard is also self-cleaning and the keys are free of damage from water, oil and dirt.The keys of the new keyboard are made of the same inexpensive plastic that might be found on any other standard keyboard. But instead of being smooth, the keys
39、have millions of tiny plastic nanowires(纳米线)on their surface area to every key, increasing the effective contact area between the plastics and fingers. This ensures that theres enough power to run the keyboard as someone types.Liming Dai, a scientist, did not work on the new keyboard, but he thinks
40、the design could be important in getting better performance from a variety of devices. “It could also be applied to a touch screen, for instance,” Dai says. “Then smartphones and notepads could harvest energy from the action of someone typing or drawing.”“Future work might make the keyboard even mor

45、ed an electric car into a mobile laboratory named “DriveLAB” in order to understand the challenges faced by older drivers and to discover where the key stress points are.Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to
46、 them becoming more isolated(隔绝) and inactive.Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life.These include custom-made navigation(导航) tools, night vision systems and intelli
47、gent speed adaptations. Phil Blythe explains: “For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.”But we all have to accept that as we get old
48、er our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to.Dr Amy Guo, the leading researcher on the older driver study, explains,
49、 The Drive LAB is helping us to understand what the key points and difficulties are for older drivers and how we might use technology to address these problems.For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they s
50、truggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. Were looking at the benefits of systems which control their speed as a way of preventing that.We hope that our work will help with technological solutions(解决方案) to ensure that older

One of the most widely used location(位置)services is Google
54、 Maps. When someone uses Google Maps, information about times and locations are recorded and stored.Google also uses tracking tools with other services. Weather apps, for example,are designed to identify a users location to provide local weather information. Even some Google Internet searches can re
55、sult in the collection of information about exactly where a person was when the search was made.Google says it collects the data to improve users localized experiences. But such practices have also raised privacy concerns. Privacy activists have called on Google and other major technology companies
56、to make it easier for users to turn off location services if they do not want to be tracked. In some ways, Google is clear about asking permission to use location information. For instance, Google Maps will seek approval from a user to give the app access to locations. If a user agrees to let Google
57、 collect location information over time, Google Maps will show this history in a timeline that shows the personas daily movements.Google also has a Location Historysetting. The company says any user can turn off Location History at any time. And when Location History is turned off for a users accoun
58、t, it is turned off for all equipment linked to that Google account. But the AP (Associated Press) found this does not appear to be true, finding that Google continued to save location history even if a user had turned off Location History.Google states users can stop the saving of all location mark
59、ers by turning off another setting, however, which is not clearly identified as being connected to location tracking. The setting is called Web and App Activityn. It stores different kinds of information from Google apps and websites to a users Google account.1.Why does the author mention Weather ap
60、ps?A.To stress Google sendees are widely used.B.To show many apps can track a users location.C.To prove Google collects users data illegally.D.To advise people to stop using them.2.What is the voice from the privacy activists?A.Users should use the Internet less.B.Google should stop tracking users.C

63、e bike at home may keep you in physical shape, but it can get pretty boring after a while. Aaron Puzey had been on his exercise bike for half an hour a day for years when he decided to look for a way to make it a bit more fun.With virtual reality technology widely available nowadays, all he needed t
64、o do was find a way of applying it to his needs. So he set out to build an app for the Samsung Galaxy Gear VR headset(头戴式视图器) which would allow him to hook it up to Google Street view and make it seem like hes cycling through different real-life locations.Building the app to download the 3D data fro
65、m Street View and make it viewable in the VR headset was the toughest part of his project. Other than that, all he needed to do was tape a Bluetooth monitor to his exercise bike. Although the quality of the images sometimes leaves a lot to be desired, leaving complex scenes like trees looking like a
66、 mess, Aaron has been having a lot of fun on his journey.Aarons project is obviously no substitute(替代品) for real outdoor cycling as it lacks things like the wind blowing in your face or the pain of battling an uphill climb, but it has given him a goal, as well as the chance to take in the beauty of
67、places he might have otherwise never seen. It definitely beats staring at a wall or at the TV for 30 minutes, anyway.Obviously, Aarons set up the officially allows him to ride a bike anywhere around the world. He says he has always wanted to see Japan, so once his ride comes to an end, he plans to s

You may have entered one out of curiosity,or y
71、ou may think it is just another piece of useless technology. Whatever your opinion,VR,or virtual (虚拟的)reality, is going to become a big part of our lives very soon.2016 saw the introduction of many fancy products in the world of VR,including Microsofts HoloLens and Samsungs Gear VR. All of them offe
72、r an exciting look at the new realities and opportunities that VR brings. These,however, are the early days of a technology that is expected to go from strength to strength. And 2017 looks like it is going to be the year in which VR technology really takes off.For a start, using VR will become more
73、normal in 2017. Microsoft and Intel have already discussed their plans for simpler and less expensive VR headsets.The idea of VR will stop being a sci-fi (science fiction) idea, and instead it will turn into an industry of real products used as ways to show off imagination, said Andrew, a designer a
74、t US VR company, Survios. It is also expected that VR products will play a part in more common and real-life fields like fashion and film. For example, to enjoy the atmosphere and energy of the front row experience at a fashion show,fans will no longer have to go along in the flesh. Instead people w
75、ill be able to enjoy the experience by just wearing a VR headset at home.You can also expect VR mirrors and fitting rooms sooner rather than later. This is an especially good opportunity for brands looking to offer very personalized experiences, said Roy De Young from US-based marketing agency, PMX.

But besides business people there are many other people who are interested in getting one. Students are very interested in the latest technology. So you cannot keep Apple iPad awa
79、y from students.The question is: Should they buy an Apple iPad?Apple iPad has many features that would work for students, which means that students do not have to carry books for reference. They can use e-books because Apple iPad has a big screen that makes reading a pleasure. You can even write on
80、iPad. So it works as an all-in-one tool that is so light that it can be put in any backpack. The battery life of Apple iPad is around 10 hours, which is clearly a good point for students. The touch screen is big and iPad does not create any noise while it is working. In a word, Apple iPad does have
81、some features that would do good to students.However, students might have to slow down their work because Apple iPad struggles when it comes to doing many tasks at the same time. It would create a problem if the student has to take down notes quickly while the iPad does not allow him/her to work wel
82、l. Another thing that students might not be happy with is that there is no keyboard.Though iPad has an on-screen keyboard, it might not be as useful as a real keyboard. Apple iPad has no USB port(端口)or SD card slot (插卡槽), which means students will not be able to share information quickly among thems
83、elves.Therefore, I dont think its necessary for students to buy an iPad. It may not work as well as they expect. They can buy a netbook for their study. It would work better for them.1.What is the author mainly talking about?A.Who should buy an Apple iPad.B.What an Apple iPad can do for students.C.W

But it will be more famous for making your next ho
86、liday come more quickly. The space agency is working on a new plane, which could solve the problems of supersonic(超音速的) flight and vastly increase the speed of journeys abroad. If successful, the plane would be able to fly between New York and London in just three hours. And it would reduce the time
87、 spent flying other journeys by a half, since it could be used more broadly. Until now, the problem with such planes has been the sonic boom(声爆), made famous by the original Concorde. That happens when a plane reaches supersonic speeds. It is a thunderous noise that upsets people on the ground- dist
88、urbing animals and even causing physical problems to materials and houses underneath. It was that effect that led Congress to ban such planes from being used over the US land, a decision that in turn was responsible for Concordes failing to be commercially used. In view of the problem, the space age
89、ncy has developed a new technology and tried it out in wind tunnels, and now believes that it could be put to commercial use. That plane will fly as high as 55,000 feet- far higher than normal planes-and make a sound of only 60 decibels. Thats far less than 90 decibels thrown out by normal planes, a

94、ography is not making us dumber. It is shifting the way our minds work, refocusing our attention.Alixandra Barasch, a cognitive(认知的) scientist at New York University, has run similar studies at Stanford, where participants either take photos or dont take photos while on a museum tour. When instructe
95、d to take photos of an exhibit, her participants were more likely to remember visual aspects of their experience (the art and other things they saw) than if they didnt take photos. But theres a trade-off : The participants taking photos were less likely to remember information they heard.Photos are
96、increasing visual memories. Barasch says, but it doesnt come without a cost. And that cost is our attention. If we are so focused on photos and visuals, we are more likely to ignore other things around us. And what gets ignored does not get remembered.The lesson here is that were probably limiting o

When we look back on those photos, they do serve as memory cues, but theyre not necessarily reminding us of the whole story. They were taken merely by our eyes. What
98、were other senses doing then? says Linda Henkel, a psychologist from Fairfield University.Baraschs research finds evidence that smartphones are changing what we notice they are redirecting or refocusing our attention.

These lap
102、tops connect people to their workplace. In the United States today, laptops also connect students to their classrooms. Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the colle
103、ge will receive a laptop. The laptops are part of a $ 10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. Besides, they will be able to use e-mail to “speak” with their teachers, their classmates, and their families. Howev
104、er, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the treesanywhere at all!Because of the many changes in computer technology, laptop use in higher educati
105、on, such as colleges and universities，is workable(可行的）.As laptops become more powerful, they become more similar to desktop computers. Also, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher education officials are studying how

109、early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replie
110、s, “No, thanks. Ive got a good horse under me.” The city planners decided to build an underground drainage(排水) system, but there simply wasnt enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city. An engin
111、eer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the citys streets by as much as 12 feet. This of course created a new problem: dirt practically buried the first floors of every building in
112、 Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level.
