Although air travel comes with jet lag, delays and awful food, it offers a brief digital detox—a precious few hours away from the wave of emails, messages and app announcements. But not anymore, In flight Wi-Fi is getting faster and cheaper, and is an increasingly common offering on budget and flagship airlines.
But how does in-flight Wi-Fi actually work? To simplify, there are two ways for an internet signal to reach your device when you’re up in the clouds. The first is via ground based mobile broadband towers, which send signals up to the aircraft’s antennas (天线). As you travel into different sections of airspace, the plane automatically connects to signals from the nearest tower, so there is (in theory at least) no interruption to your Internet. But if you’re passing over large areas of water or particularly remote zones, connectivity can be an issue.
The second method uses satellite technology. Planes connect to satellites in space (35,000 km above the planet), which send and receive signals via receivers and transmitters. Information is transmitted to and from your smart phone via an antenna on the top of the aircraft. These are the same satellites that are used in television signals and weather forecasting. Information is passed between the ground and the plane via the satellite.
All of that technology is expensive. The costs are usually passed on to customers. Over half of the world’s aircraft will be equipped with in-flight Wi-Fi within the next few years. It is set to become a billion-dollar industry by 2020. In the near future you’ll need to find a better excuse than “Sorry I missed your message—I was on a plane”.
1.What sends signals up to the aircraft’s antennas?
A.Internet companies. B.Ground-based receivers.
C.Budget and flagship airlines. D.Ground-based mobile broadband towers.
2.Who will pay for the in-flight Wi-Fi technology in the end?
A.Aircraft passengers. B.Satellite company.
C.Broadband towers. D.The local government.
3.What can we infer about in-flight Wi-Fi from the last paragraph?
A.It serves every customer. B.It has a bright future.
C.It develops very slow. D.It’s a high-tech industry.
4.What is the best title for the text?
A.How to Use In-flight Wi-Fi? B.Why Only Some Airlines Have In-flight Wi-Fi?
C.Why Is In-flight Wi-Fi Expensive? D.How Wi-Fi Works on a Plane?

Do you like air travel with a service dog? Air travel makes some people very nervous. The crowds, the noise and flying itself can cause unease. But there are classes people can take to help them defeat their fear of flying. And, let me introduce similar training for service dogs that suffer the same problem
Service dogs almost never leave the side of the people they care for. You will see them working on buses, trains and other public transport systems. But the busy environment found at an airport can trouble even the best trained working dog.
People with disabilities depend on their dogs. They want the animals to safely guide them through security areas. They also need the dogs to remain calm on duty on the plane, even when the flying is not smooth. This takes special training. The Air Hollywood K9 Flight School is one place where such help can be found.
The school has a piece of equipment that provides the sights, sounds and even the feel of an airplane in flight. It is called a flight simulator, which was built for filming airplane scenes in movies.
Sandy Alexander has a disability that requires his two-year-old dog, Doc, to be always at his side. Mr. Alexander took the dog to the flight school to get him ready for plane trips. He says Doc did not like the bumpy part of the flight simulation( 模拟).
Dog trainer Mary Segall is with Canine Companions for Independence. It provides dogs for people with disabilities. Ms Segall says successful training is based on a simple rule: preparation.
" Dogs need to be exposed gradually and repetitively to stimulation, to the environment, to loud noises, to sounds and to other dogs so that when this experience happens to them on a daily basis, they are able to act in a way that they're used to acting and that they don't get excitable."
Dog owners who attended the training at Air Hollywood K9 Flight School say they now feel much more at ease about future flight. Their dogs also seem ready for take-off.
1.How does the author introduce the topic of the text?
A. By asking a question. B. By introducing a novel.
C. By comparing fear of flying. D. By giving an example.
2.Why is Sandy Alexander's example given in Paragraph 5?
A. Because he likes dogs.
B. Because his dog is clever.
C. Because he will play a role in a film.
D. Because the author wants to develop the following paragraphs.
3.From the last paragraph we can draw a conclusion that ________.
A. the training is very easy
B. service dogs don't like flying with their owners
C. service dogs adapt themselves to the stimulation slowly.
D. dog owners are satisfied with training

When Cherry Watson travelled on a recent flight from New York to Washington and noticed an “awful tension” in the cabin, she first thought it was caused by typical bad-tempered passengers. But as the flight neared its end, it became obvious that something was very wrong.
A teenage boy with Down Syndrome (唐氏综合症) who was traveling with his family had become upset and would not return to his seat, regardless of the cabin crew’s warnings over the loudspeaker that it was almost time to land. The pilot was forced to circle above the airport, delaying the landing and angering people on the already tense flight.
“If it was a cartoon,” remembered Watson, “there would have been smoke coming out of people’s ears.”
The boy’s elderly parents and adult brothers and sisters tried to persuade him to get off the floor and back into his seat, but in vain.Watson, who used to be a teacher, stood up and quickly headed to the back of the plane.
She found the boy in the passage between rows of seats, lying on his belly, and lay down on her stomach to face him. She began chatting calmly with him, asking his name, his favorite book, and his favorite characters. He told her he felt sick and she tried to comfort him.
Minutes later, he allowed her to hold his hand, and then together they got properly back into airplane seats. Watson asked for sick bags, and held them as the boy threw up several times, including on her. As she helped him clean up, she repeatedly told him everything would be okay and that they’d get through it together.
After the plane was finally able to land, no one was impatient to step off the flight as one might expect. Instead, calmed passengers—obviously following Watson’s amazing example—allowed the boy and his family to depart first, smiling at them as they passed. His parents tearfully thanked Watson for what she had done, and a doctor sitting nearby also let her know he had even taken notes on her expert way of handling the situation.
1.The landing was delayed because _____.
A. the plane was out of control.
B. the pilot was forced to change the destination
C. a family ignored the warnings
D. a boy refused to sit in his seat
2.Watson successfully handled the “awful tension” by _____.
A. fighting against unfair treatment
B. calling on other passengers to join her
C. asking an experienced doctor to help
D. communicating with the boy
3.What changed the angry passengers’ attitude at last?
A. Watson’s efforts. B. The plane’s safe landing.
C. The crew’s behavior. D. The boy’s improvement.
4.Which of the following words can best describe Watson?
A. Patient and ambitious. B. Kind and cool-headed.
C. Wise and cooperative. D. Generous and cautious.
5.What can be inferred from the passage?
A. Watson was not a teacher when taking the plane.
B. Smoke came out of passengers’ ears.
C. The boy could not speak because of Down Syndrome.
D. The passengers were out of patience when the plane landed.

Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil(不存在), many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne(升空的).
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
Choose larger aircraft
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply(遵守)with much stricter regulations and are tested more regularly to make sure they still comply. Also, in t he unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
Pay attention to the pre-flight safety briefing
The information may seem repetitious(重复的), but it's worth listening to the flight attendants. And even if you’ve flown before, it doesn’t mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence(气流).
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it’s important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.
1.Whom is the passage meant for?
A. Pilots. B. Flight attendants. C. Passengers. D. Airlines.
2.The underlined word “those” in the second tip refers to”______” .
A. smaller planes B. passengers C. larger aircrafts D. safety records
3.What does the author really mean by saying “Cabin crew always tells you this, but it’s important.” In the 5th tip?
A. Many people don’t pay enough attention to fastening their seat belt.
B. All passengers are glad to accept the crew’s advice.
C. The crew are very responsible.
D. There is no need to remind people to fasten their seat belt.
4.Which of the following is not true according to the passage?
A. Larger planes have more safety checks and are safer.
B. Take-offs are safer on non-stop flights than landings.
C. Every aircraft is different, so the safety procedures may be different.
D. Seat belts should be worn to protect against turbulence.
5.The best title of the passage should be”_____”.
A. The safest way to travel B. Air safety tips
C. Non-stop routes D. How to fly a plane

Get the flu shot (疫苗)

Sony has a new device for anyone who's ever wished they could carry their air conditioner on hot summer days.
Called Reon Pocket, the small, lightweight machine slides into the upper back pocket of a specially designed T-shirt. Controlled with a smart phone app, it's capable of heating or cooling the wearer via the Peltier effect, a thermodynamic (热力学) principle widely used in refrigeration.
The Reon Pocket comes out of Sony’ s startup acceleration program, and Sony is currently crowdfunding (众筹) the device. Supporters can choose from a few different packages, if they want multiple T-shirts for instance, but a basic one including the device and one shirt costs ¥14, 080. There's a catch, though: Sony only has plans to release the Reon Pocket in Japan at present.
The target audience is mostly businessmen who have to wear a suit in the summer, though the company says it will judge its wider relevance based on the crowdfunding results. Right now, though, the T-shirts available come in men's sizes, small, medium, or large.
The device is not really for all- day use so much as moving between air-conditioned or heated areas, such as travelling to work. The battery takes around two hours to charge and lasts about 90 minutes.
In a blog post from Sony's startup accelerator, Yoichi Ito, a project leader on Reon Pocket, said his team started thinking of ways to combine technology with fashion. Reon Pocket was the result. Japanese buyers looking to battle the record heat this summer will have to wait, though. If the crowdfunding is successful, deliveries of the device are scheduled to begin in July 2020.
1.Which of the following can be used to describe the new device?
A.Portable. B.Widely- used. C.Plain. D.Energy- saving.
2.What does the underlined word “packages” in Paragraph 3 refer to?
A.Sets of T-shirts. B.Sets of programs. C.Sets of services. D.Sets of items.
3.What can we infer about the new device from the passage?
A.Only businessmen can have free access to it. B.The fundraising affects its popularization.
C.Its special design makes it sell well in Japan. D.It can be rechargeable with a long life battery.
4.What's the author's purpose of writing the text?
A.To popularize modern conveniences. B.To combine technology and fashion.
C.To introduce a new electric device. D.To raise money for a good cause.
