Howdo you turn “dumb” headphones into smart ones? Rutgers engineers have invented a cheap and easy way by transforming headphones into sensors that can be plugged into (插入) smartphones, identify their users monitor their heart rates and perform other services.
Their invention, called HeadFi, is based on a small plug-in headphone adapter that turns a regular headphone into a sensing device (装置). Unlike smart headphones, regular headphones lack sensors. HeadFi would allow users to avoid having to buy a new pairof smart headphones with sensors to enjoy sensing features.
“HeadFi could turn hundreds of millions of existing, regular headphones worldwide into intelligent ones with a simple upgrade (升级),” said Xiaoran Fan, a HeadFi primary inventor.
A Rutgers-led paper on the invention, which results in "earable intelligence", will be formally published in October at MobiCom 2021, the top international conference on mobile computing and mobile and wireless networking. Headphones are among the most popular wearable devices worldwide and they continue to become; more intelligent as new functions appear, such as touch-based gesture control, the paper notes. Such functions usually rely on aiding sensors, such as accelerometers, gyroscopes and microphones that are availableon many smart headphones.
HeadFi turns the two drivers already inside all headphones into a versatile (多功能的) sensor, and it works by connecting headphones to a pairing device, such as a smartphone. It doesn't require adding aiding sensors and avoids changes to headphone hardware or the need to customize headphones, both of which may increase their weight and size. By plugging into HeadFi, a converted headphone can perform sensing tasks and play music at the same time.
The engineers conducted experiments with 53 volunteers using 54 pairs of headphones with prices ranging from $2. 99 to $15 ,000. HeadFi can achieve 97. 2 percent to 99. 5 percent accuracy on user identification, 96.8 percent
to 99. 2 percent on heart rate monitoring and 97. 7 percent to 99. 3 percent on gesture recognition.
4. What does Xiaoran Fan think of HeadFi?
A. Secure to operate.
B. Simple to use.
C. Easy to substitute.
D. Convenient to store.
5. What can we know about HeadFi according to the text?
A. It can't work with headphones alone.
B. It actually functions as a versatile sensor.
C. It makes headphones larger and heavier than usual.
D. It doesn't work when headphones are playing music.
6. The figures are listed in the last paragraph mainly to show_________.
A. the various functions of HeadFi
B. the wide popularity of headphones
C. the great complexity of headphones
D. the excellent performance of HeadFi
7. What can be the best title for the text?
A. How to Use Headphones Appropriately
B. Headphones Can Be Upgraded Instantly
C. How to Make Regular Headphones Intelligent
D. New Uses Have Been Found in Headphones
C
Jon Pedley is making a big change. He is giving up his life as a businessman for a life of helping others. He is trading his beautiful farmhouse in England for life in a mud hut in Uganda, East Africa.
Pedley admits that he has notalways led a very positive life. At times he drank too much and got in trouble with the law. “I’ve always put the pursuit of money in front of everything else. As long as I was all right, I didn’t care who I was hurting, ” says Pedley.
But a visit to Uganda in 2007 gave Pedley a new outlook on life. He was amazed at what he saw and how much the people there appreciated the work he was doing. “I worked there for a few days and these people who have nothing were thanking me by giving me bags of potatoes, which are a fortune for them,” he said.
Now Pedley is selling his business, his $1.5 million farmhouse, and his expensive car — and moving into a hut made of mud and boards in a small Ugandan village. There he will help run an organization that hopes to improve the quality of life for people in the village of Kigazi. He will help to build schoolrooms for children and tanks to hold clean water for villagers. Today, people in Kigazi must walk two miles to a hospital, so Pedley will help to build
doctors’ offices, too.
Pedley’s organization will also work with English teenagers who are in trouble. The teens will be sent to a “camp” in Uganda that Pedley will run. The teens will live in mud huts and help to build water, health, and education facilities for kids in Kigazi, many of whom have lost their parents to poverty or disease. Pedley hopes the teens will see a side of life that might help them turn around their own lives and set them on a new and more positive path.
8. Which of the following best describes Pedley’s life in the past?
A. Negative.
B. Colorful.
C. Independent.
D. Selfish.
9. What will Pedley do in the small Ugandan village?
A. Do business with the local people.
B. Help farmers increase potato output.
C. Assist villagers with construction work.
D. Introduce tools to improve English teaching.
10. Why will Pedley work with English teenagers in trouble?
A. To encourage them to make friends with locals.
B. To inspire them to live a more positive life.
C. To train them to become doctors in the future.
D. To make them learn about different cultures.
11. What is the best title for the text?
A. From millionaire to mud hut
B. A life-changing adventure
C. A rich man becoming homeless
D. More money, more worries
D
Flying someone one-way fromLondontoNew Yorkproduces nearly a ton ofcarbon dioxide or CO2. That's alot of this climate-warming greenhouse gas. But there are ways to cut the climate impact of flying, one of which is to ask planes to surf high-altitude winds every chance they get.
It's not something they've been allowed to do. But that may change—and soon.
Most jets crossing the Atlantic Ocean follow one of several fixed paths that are widely spaced because radar (雷达) had not been able to track aircraft everywhere above the Atlantic. But a new network of satellites could soon change that.
Wells was part of a team inEnglandthat calculated the fastest possible routes for passenger planes. According to them , traveltime a plane takes when flying across theAtlanticvaries with the winds that a plane meets. For instance, eastbound (向东的) flights can get a powerful push. Westbound routes miss that benefit. Faster flights burn less fuel. And less burning gives off fewergreenhouse gases.
The airline industry knows it has a high " carbon footprint." But it takes decades and many billions of dollars
to design, test and fly new planes. Changing a flight path, in contrast, can cut costs and energy right away.
The new study doesn't show how well such wind surfing would work for all planes, in all skies and the world over. Bui it does suggest that making flight routes more flexible could cut both fuel use and CO2in some places.
However, if flight times vary depending on the wind, scheduling connecting flights and managing runways and gates would become more complicated. The researchers would have to work out the best flight paths that take such scheduling issues into consideration. They may also want to see if flying at different altitudes gives a wider choice of flexible routes at the times most people want to fly.
National Air Traffic Services (NATS) which provides air-traffic control for theUnited Kingdomsaid it would temporarily disband its flight-paths system and work to allow airlines to choose flexible routes that would best limit their fuel use.
12. What happens to east bound flights when crossing theAtlantic?
A. They consume more fuel.
B. They use less time and energy.
C. They produce more greenhouse gases.
D. They are against a stronger wind.
13. What should be done to make adopting flexible flight routes possible?
A. Calculating the flight time.
B. Finding the best flight paths.
C. Adjusting the size of jets.
D. Adding more runways and gates.
14. Which word can best replace the underlined word "disband” in the last paragraph?
A. Stop.
B. Copy.
C. Handle.
D. Restore.
15. What can we infer from the text?
A. Planes are producing the most carbon dioxide.
B. New fuel is benefiting airline industries greatly.
C. Carbon footprint is a serious problem in theUK.
D. Surfing the winds can make air travel greener.

My high school life will over, but the coming-of-age ceremony still stays in my mind.
That day we came to school early than usual and gathered in the front of the teaching building. We first went through a red gate made of balloons, that indicated we had become adult. Our parents were invited to be present and sat beside me. After the headmaster made a speech, we were required to exchanging our letters with our parents. As tears roll down our cheeks, we began to hug our parents tightly because we realized they loved us so deep.
The activity reminded us that we were no longer children from then on. We should study even harder to bring about our best qualities.
