Arthur Lih of Massapequa sold his first LifeVac, a device to help save people’s life, to a fire department about 18 months ago, when the Jericho Fire Department purchased 21 of the devices. Now about 10 Long Island fire departments have purchased Lih’s invention, which is designed to draw foreign objects from the throats of choking victims when procedures such as the Heimlich Maneuver (海姆立克急救法) don’t work. He has sold about 5,000 LifeVac devices in the United States and abroad since the device went on the market in August 2014.
The Freeport Fire Department is one of Lih’s clients. It bought about 25 LifeVac devices to put on trucks, as well as in chiefs’ vehicles, said Ray Maguire, the department’s executive director. “It’s an extra tool in the toolbox,” Maguire said. “I’d be surprised if anyone who sees it doesn’t purchase it. It’s that tool you may only need once, but it’s the tool you really want in case you need it. It’s affordable. I have it in my car. I have one at home, too.”
Dr. Lee Smith at Northwell Health said that if a choking victim can’t breathe, he or she becomes a candidate for the Heimlich. If the Heimlich doesn’t work, the victim would probably lose consciousness because of a lack of oxygen.
A challenge for any new medical device is convincing potential users that it works and is safe. In tests, the LifeVac successfully removed an obstruction (阻塞物) from the throat of a dead human body on the first try 49 out of 50 times, according to an August research article in the American Journal of Emergency Medicine.
Lih invented the product in his garage, inspired after he went with a friend to a hospital while the friend’s mother was going through tests. The friend said the last time he was there, a 7-year-old child had choked to death on a grape.

【推荐2】Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn't exist. That changed because of a man named Joseph Merlin. Merlin's work was making musical instruments. In his spare time he liked to play the violin. Joseph Merlin was a man of ideas and dreams. People called him a dreamer.
One day Merlin received an invitation to attend a fancy dress ball. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make a grand entrance at the party. He had an idea. He thought he would get a lot of attention if he could skate into the room.
Merlin tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.
On the night of the party Merlin rolled into the room playing his violin. Everyone was astonished to see him. There was just one problem. Merlin had no way to stop his roller skates. He rolled on and on. Suddenly, he ran into a huge mirror that was hanging on the wall. Down fell the mirror, breaking to pieces. Nobody forgot Merlin's grand entrance for a long time!

【推荐3】For anyone coming of age (成年) in the last 60 years, Lego has been a long-standing friend. The tiny plastic bricks that fit together have provided great pleasure for generations.
In 1932, Christiansen founded the construction toy company the Lego Group. By 1949, his company began producing tiny plastic building bricks that children seemed to love. Nine years later, the Lego bricks took shape. Lego also kept pace with technology. Through the 1980s, Lego sets began to include electric lights and sound-making equipment. But by 2003, Lego nearly went broke (破产) as the firm dealt with changing play habits. Kids were more interested in playing video games and surfing the Internet than playing with Lego bricks.
The company took quick action. Within 10 years, Lego achieved great success. It was mainly because of Lego’s Future Lab. The lab was made up of 50 or so researchers, scientists and designers. Their job was to invent new play experiences for children. To that end, the company joined hands with universities and others in the hope of finding out what kids wanted. And the effort finally paid off.
“From the youngest builders to adults, we have a Lego solution for every builder of any age, building skill and interest for any play occasion,” Amanda Madore, senior manager at Lego Systems Inc, said. “We focus on what the brand means to children—both physically and digitally—and we continue to serve their needs, so we believe our business potential is as limitless as our play material.”
Although Lego bricks have always been fun to play with, research has shown they can be central to a child’s education and cognitive acuity (认知敏锐度). Specifically, Lego bricks are an important tool that can help children with autism (自闭症). Research has found that children with autism become more social and communicative while playing with the bricks in group settings. Part of the reason is that Lego requires children to communicate, set rules, make decisions and work with others. In this sense, Lego bricks are hard to replace.

【推荐1】The announcement that Indhu Rubasingham is to be the artist director of the Royal National Theatre (NT) in 2025 has been met with cheers, within the industry and without.
Workmates at the Kiln theatre in Brent, where Rubasingham has been director since 2012, describe her as inspiring, risk-taking and tough. Rufus Norris has called her “an exceptional artist who I respect and admire hugely”.
Rubasingham may be the NT’s female artistic director and the first person of colour in the role, but her own achievements contribute to her position. From a theatre with just 292 seats, she has commissioned (委托) and created productions of international quality. There has been Florian Zeller’s trilogy The father, The Mother and the Son and her production of Zadie Smith’s The Wife of Willesden. A recent success is Ryan Calais Cameron’s civil rights story Retrograde.
Rubasingham is not new to National Theatre: as Norris says, “it’s a place she knows well, having directed successfully in each of the three theatres”. However, it’s a big leap from the 292 seats of the Kiln to the challenges of NT, with 2,450 seats, plus outreach, educational and digital programs. All this has to be done against the worst financial (金融的) situations since the NT was founded in 1963．Today, any director of a national arts organization in the UK faces a hard time, with the financial black hole left by the pandemic (疫情).
Rubasingham, however, is all about the artists: the play-writers and actors and many other creative talents who make her theatre what it is. That’s the special talent she brings to this position. She herself has described it as “the best job in the world”.
1. What can we learn about Rubasingham from the first two paragraphs?| A．She is envied by Rufus Norris. |
| B．She is welcomed to take the position. |
| C．She doesn’t get along with workmates. |
| D．She has moved from the Kiln to the NT. |
| A．To praise her success in directing. |
| B．To promote her works internationally. |
| C．To introduce her understanding of art. |
| D．To show her relationship with play-writers. |
| A．The pandemic. | B．Little experience. |

【推荐2】Do you have bright ideas? Ideas for inventions that change society or, at least, make life easier for somebody? Perhaps we all do sometimes but we don’t often make the idea come true. Recently, in Britain, there was a competition called British Designers for Tomorrow. The competition encouraged young people to carry out their bright ideas. There were two groups in the contest: Group One was for school children over 16. And there were eleven prize-winners altogether.
Neil Hunt, one of the prize-winners, was called “Sunshine Superman”. It’s important when people study the weather to be able to record sunshine. We need to know how many hours of sunshine we have and how strong it is. Most sunshine records only record direct sunlight. Neil’s is accurate and this is very important for research into way of using its power.
You can do so much with animated cartoon. Look at Simon West’s idea for animated road signs. He uses pictures which appear to move as you go nearer to or farther from them. This isn’t a new idea. But it is new to use these pictures on road signs. “We found that people were likely to see moving signs,” said Simon. So now, you can really see rocks falling, trains moving, horses running or car falling over the edge of a cliff. Quite a warning!
The ideas in the competition were so inventive that we are surprised that British industry doesn’t ask more school children for suggestions. Perhaps this will be the start of “pupil power”!

【推荐3】An 89-year-old man from the American state of Rhode Island has reached a goal he spent 20 years working toward and nearly a lifetime thinking about. He earned his doctorate (博士学位), and became a physicist.
Steiner values this degree because it is what he always wanted. "But I made it, and this was the most gratifying point in my life, to finish it," he told The Associated Press.
As a young person, Steiner wanted to become a physicist after reading about Albert Einstein and Max Planck. But after World War II, his mother and uncle advised him that studying medicine would be a better choice. He earned his medical degree from the University of Vienna in 1955 and moved to the United States soon after. In the U.S., he had a successful career studying blood and blood conditions, or hematology(血液学). He was a full professor and led the hematology department at Brown's medical school from 1985 to 1994.
Steiner helped establish a research program in hematology at the University of North Carolina. He directed that program until he retired from medicine in 2000 and returned to Rhode Island.
Steiner found medical research pleasing, but it was not quite the same as his interest in physics.
At age 70, he started taking undergraduate classes at Brown. By 2007, he had earned enough credits (学分)to join the doctoral program.
Physics professor Brad Marston was surprised when Steiner entered his quantum mechanics(量子力学) class. Marston had taught graduate students in their 40s, but never in their 70s. But the professor soon realized how serious Steiner was about the subject and how hard he worked.
Marston became Steiner's adviser for his dissertation(学位论文).
"He has written many papers in medical science, more papers than I've written in physics. He already had a scientific way of thinking that younger students have to develop," Marston said. "One thing that's really true about Manfred is he perseveres(坚持)."
Steiner defended his dissertation in September after recovering from a serious medical condition.
Steiner now hopes to help the professors he befriended during his studies with their research.
After the university published a story about Steiner on its website, people across the U.S. contacted him to ask for advice on how to go after their dreams later in life.
He said his advice is: Do what you love to do.

【推荐1】Summer is the swimming season. As fun as a swimming pool can be, it’s also a major safety risk if you don’t take the proper measures. Here are some tips for a safe swimming season.
Have supervisors (监护人) to watch over the safety.
Keep a variety of floating devices in and around the pool like a life jacket plus pool noodles or a paddle board. That helps when accidents happen.
Supervisors should also learn basic CPR. It only takes three steps, which is easy to learn. However, it saves life in the “golden four minutes” right after accidents happen.
Another risk is a condition called “dry drowning”. This happens after a near-drowning event in which water gets into someone’s lungs.
| A．Drowning can happen in an instant |
| B．Drowning isn’t the only danger with pools |
| C．Pool owners should be sure to have a fence around their pool |
| D．When someone is drowning, they should call for help as quickly as possible |
| E．A drowning person having something to grab can get out of the pool quickly |
| F．That means the airway is closed off and can’t provide someone with enough oxygen |
| G．If children or inexperienced swimmers are in the pool, it’s very important to have close supervision |
【推荐2】IT’S IMPORTANT TO KEEP your kit accessible because you never know when you’ll need it. In fact, statistics indicate that more medically reported injuries happen at home than in public places, at the work place and on the road combined. To ensure you are adequately prepared for any emergency, here are the essential basics.
● Buy the Right Container
Your first-aid items should be kept in a waterproof bag or an airtight container with clear sections that allow you to quickly see what’s inside.
●
It’s essential to regularly review and refill your first-aid kit contents to ensure that it is adequately stocked and all supplies are in good condition. Check the expiration(过期) dates of all medications and promptly replace any that have expired.
● Get Some Training
There’s no better way to prepare yourself for emergencies than by taking a course.
● Know When to Get Help
| A．Check Expiration Dates |
| B．Keep Your Kit Up-to-Date |
| C．Any cut longer than 1 inch will need stitches. |
| D．Consider engaging in practical training for better emergency skills. |
| E．Organizations like the RedCross offer weekend basic first aid certifications. |
| F．Also, make sure that you have enough supplies for any potential emergencies. |
| G．That way you won’t have to dig around or dump things out of the kit to find what you need. |
【推荐3】When You Get a Cut …
Your skin’s most important job is to keep out the billions of harmful bacteria that swarm over every surface. Any wound that penetrates the dermis (真皮) layer and causes bleeding will allow bacteria to get in, so we have evolved a precisely coordinated mechanism to seal up the gap as quickly as possible. The healing process uses extra collagen (胶原) protein for the repair, so the new skin is actually stronger than before. This shows as a visible scar.
|
|
|
| 1. HAEMOSTASIS (止血) When the skin is cut, blood vessels contract and platelets (血小板) release fibrin proteins (纤维蛋白) that tangle together to form a clot (血凝块) and seal the wound. | 2. INFLAMMATION Next, the blood vessels expand again to allow white blood cells to flock to the wound site. These attack any bacteria that got past the clot. | 3. PROLIFERATION After a few days, fibroblast cells (成纤维细胞) arrive and produce collagen. This protein acts like a scaffold (脚手架), while the dermis cells reproduce to close up the wound. |
|
|
|
| 1. KEEP IT CLEAN Wash the open cut to prevent bacteria getting trapped inside. Don’t use disinfectant (消毒剂) because this will kill your own cells that are trying to repair the wound. | 2. SEAL IT A plaster keeps dirt out and helps the clot form. If the wound is still bleeding after 10 minutes with a plaster on, you may need stitches (缝针). | 3. SCARRING The skin continually rebuilds the collagen matrix (基质) for up to a year after the cut. This scar tissue will fade slightly for another year after that. |
| A．collagen protein | B．dermis cells | C．fibrin proteins | D．blood vessels |
a. clot
b. collagen
c. white cells
d. platelets
e. dermis cells
| A．bdace | B．daceb | C．dacbe | D．bedac |
| A．Disinfectant should be applied right after the cut. |
| B．White blood cells will reproduce to close up the wound. |
| C．Once a clot is formed, there are no bacteria inside. |
| D．Stitches are needed when a plaster fails to stop the bleeding. |
