Similar technology could greatly reduce broken hips (髋部) resulting from a fall, something most seniors fear.Dr Robert Buckman and his startup company, ActiveProtective in Allentown, Pennsylvania, has developed a promising solution, a wearable airbag that can protect hip bones in the event of a fall. The idea was the result of Dr Buckmans years as a doctor at Temple University. He noticed how many elderly people were being brought into hospitals with broken hips due to falls, and how they often never completely recovered from the injuries. He started to ask what he could do for these people, and that was when he started trying to figure out whether there was a way of helping people who were at the highest risk of falling and suffering these kinds of injuries.The device is worn much like a regular belt, but on the outside of the clothing, it includes sensors that monitor the movement of hips. If the device detects that the person is falling, an airbag opens before the person hits the ground, cushioning the fall. When the wearer hits the ground, the bag reduces the force to the hip bones by 90 percent, enough to avoid the majority of hip injuries.With one out of every three people aged 65 and older suffering serious falls each year, ActiveProtective has a big market for its wearable device. It also has the potential to sizably reduce hiprelated health care expenses: Hip injuries among the elderly cost the US health care system in 2012 $ 30 billion, which doesnt include the longterm care expenses associated with the high percentage of patients that can no longer live independently.篇章导读：本文是一篇说明文。文章介绍了可穿戴安全气囊的发明缘由、工作原理以及可能带来的影响。1What is the purpose of the ActiveProtectives airbag?ATo avoid hip injuries among seniors.BTo protect seniors from car accidents.CTo help seniors with their daily nursing.DTo help doctors deal with serious injuries.答案：A细节理解题。根据第一段中的“Similar technology could greatly reduce broken hips (髋部) resulting from a fall, something most seniors fear.”和第二段中的“a wearable airbag that can protect hip bones in the event of a fall”可知，the ActiveProtectives airbag的目的是避免老年人髋部受伤，故选A。2What inspired Dr Robert Buckman to make the device?AA report on seniors health.BA serious fall he experienced.CHis work experiences as a doctor.DSuggestions of seniors at Temple University.答案：C细节理解题。根据第二段中的“He noticed how many elderly people were being brought into hospitals with broken hips due to falls, and how they often never completely recovered from the injuries. He started to ask what he could do for these people”可知，当医生时的所见促使Dr Robert Buckman制造这个装置，故选C。3How does the device mainly work?ABy reducing the effects of falling.BBy speeding up bone recovery.CBy predicting road conditions.DBy preventing people from falling.答案：A推理判断题。根据第三段中的“If the device detects that the person is falling, an airbag opens before the person hits the ground, cushioning the fall. When the wearer hits the ground, the bag reduces the force to the hip bones by 90 percent, enough to avoid the majority of hip injuries.”可知，这个装置在人将要摔倒在地的那一刻，安全气囊自动打开，以减弱身体撞击地面的强度；当穿戴者撞击地面时，安全气囊将髋骨受的冲击力降低了90%，这足以避免大部分的髋部受伤，故选A。4What does the author think of the ActiveProtectives airbag?AIt still needs improving.BIt has a promising future.CIt may encourage seniors to do exercise.DIt may increase Americas expenses on seniors.答案：B推理判断题。根据最后一段中的“ActiveProtective has a big market for its wearable device. It also has the potential to sizably reduce hiprelated health care expenses”可推知，这个装置前景很好，故选B项。BIn many sports, physical contact is part of the game. But when athletes hit their heads, the hit can cause concussions (脑震荡) .Concussions have long been a concern for professional athletes, but theyve become more common among young players too. Between 2001 and 2009, the number of kids under 19 visiting doctors for concussions each year increased by 62 percent.Engineers are developing new helmets (头盔), and new rules are limiting physical contact in some sports. But are these efforts enough to protect kids brains?Concussions can happen during many types of activities. But sports like football and soccer are especially risky. When you run or jump, your body is moving at an increased speed. A sudden hit causes you to move faster in a different direction.“Its like when youre on a bus and it makes a sudden stop，” says Dr Kevin Crutchfield, an expert at a sports concussion center in Baltimore, Maryland. “You hit the inside of the bus.”This hit damages the brain. It affects the way the brain functions. So some sports require athletes to wear helmets. Helmets help reduce the force of a hit. The hard outer shell spreads the force over a larger area. Inside a helmet, a plastic or airfilled lining also helps soften the blow.Steve Rowson is an engineer at Virginia Tech. In his lab, he tests how helmets hold up against different types of hits. No helmet can prevent concussions completely, says Rowson. But hes found that when wearing a newer football helmet, the players head doesnt gain speed as much after a hit. That lowers the risk of concussions.Many youth sports teams have set limits on physical contact to reduce the risk of concussions. In soccer, most concussions happen as a result of headersshots or passes made with the head. Thats why many people think kids shouldnt head the ball until high school.These efforts should help, says Crutchfield. But the best way to prevent longterm brain injuries, he says, is to stop playing immediately if you suffer concussion. “Protect yourself today so you can play again tomorrow.”篇章导读：本文是一篇说明文。青少年在运动中因头部撞击导致脑震荡的比例在逐年增高，工程师、医生和教练正采取措施预防脑震荡的发生。5Concussions among young players .Aare rare before 2001Bseem extremely worryingCcause kids to lose interest in sportsDare mostly caused by wearing no helmets答案：B推理判断题。由第二段中的“more common”和“each year increased by 62 percent”可知，青少年因体育运动导致脑震荡的情况越来越严重，令人担忧。6The author mentions the sudden stop of the bus to .Astress its dangerous to ride busesBshow human brains are easily damagedCgive a better explanation of concussionsDremind people to wear helmets while playing sports答案：C推理判断题。作者在第五段中提到公共汽车急刹车时人们会受到撞击，将之与人们在运动时发生脑震荡的情况相比较，使这一概念更容易被理解。7What does Steve Rowson think of the newer football helmets?AThey vary a lot in size.BThey work better than the old ones.CThey slow down the players running speed.DThey allow the players to move their heads more freely.答案：B细节理解题。由倒数第三段中的“But hes found that . lowers the risk of concussions.”可知，新款头盔效果更好些，可以更好地保护运动员的头部免受伤害。8Dr Crutchfield suggests that after receiving a concussion, young players should .Anever head the ballBavoid dangerous sportsCplay other kinds of sportsDstop playing the sport for a while答案：D细节理解题。由最后一段中的“stop playing immediately if you suffer concussion”可知，Crutchfield建议年轻的运动员在运动中发生脑震荡时，一定要及时停止运动，这样才能避免给大脑造成长期的损伤，才有利于今后更好地进行这项运动。.语法填空David will never forget what happened to him the day before yesterday.
