职称英语阅读理解译文理工类A级手机增加交通行人死亡手机在路上有多种多样的危险。

两个新的研究表明，不管开车还是步行时打手机，都会增加行人、司机和乘客死亡的危险，所以该研究建议严厉限制行人和司机使用手机。

这是一项第一整理为罗格斯大学纽瓦克分校的经济学教授Peter D.Loeb 的新研究成果，它把手机的意外致命的影响和大量手机使用数量了解起来，表明目前由于手机所引起的死亡数目有所增加，而在此之间的一段时间里，手机事实上能够帮助降低行人和交通致命率。

但研究发现，当手机使用人数达到1亿这个临界数量时，手机降低交通致命率的作用就消失了。

这些研究涉及到从1975年到2002年间的手机使用和机动车辆事故之间的关系，也涉及包括车速、酒精消耗、安全带的使用和行驶的里数等其它方面。

这些研究表明甚至当考虑比如速度、酒精消耗和安全带的使用这些因素时，二者之间的关联也是真实存在的。

在目前，Loeb和他的合著者决定手机的使用"在行人安全上有严重的反作用"并且"手机的使用数量已经超过了临界数量也增加了机动车辆的致命性。

"在20世纪80年代末和90年代的一段时间，在手机使用数量达到大爆炸之前，手机的使用确实在交通事故中起到过"保护生命的作用"。

"当发生交通意外时，手机使用者能够快速地打电话寻求医疗帮助，这种快速的医学求救反应确实能在一定时间内减少一定数量的事故死亡"，Loeb假设。

但是，在20世纪80年代当手机开始被使用时并不是这样，在那时手机在行人、司机和乘客间造成了"致命的效果。

"在早些日子里，那时有不到一百万部手机，致命率增加了，Loeb说，因为司机和行人或许在那时还在适应怎样使用它们，还没有足够的手机能够在事故中呼叫帮助，他解释说。

这"保护生命的效果"是在20世纪90年代当大数量的手机被使用的时候出现的，越来越多的手机在事故之后拨打911求助，这就降低了致命率，Loeb 解释说。

Of the categories, he found most6 were used by both sets of dolphins7 -- but eight were only heard from the Irish dolphins."We are building up a catalogue of the different whistle types they use and trying to associate them with behaviour like foraging, resting, socialising and the communications of groups with calves," project leader Simon Berrow said. "Essentially we are building up what is like a dictionary of words they use or sounds they make."Berrow, a marine biologist, said the dolphins' clicks are used to find their way around and locate prey. The whistles are communications. "They do a whole range of other sounds likebarks, groans and a kind of gunshot," he said. "The gunshot is an intense pulse of sound. Sperm whales use it to stun their prey."When I first heard it I was surprised as I thought sperm whales were the only species who used it. We can speculate the dolphins are using it for the same reason as the sperm whales," Berrow said.References8 in local legend indicate there have been dolphins in the Shannon estuary for generations and they may even have been resident there as far back as the 6th century9.They are regularly seen by passengers on the Shannon ferry and an estimated 25,000 tourists every year take special sightseeing tours on local boats to visit them.词汇：Irish adj. 爱尔兰的 socialise v. 社交，交往dolphin n.海豚bottle-nose dolphin 宽吻海豚 sperm whale 巨头鲸click n. 咔哒声，喀嚓声estuary n. 河口，江口vocalisation n. 发声shed n. 小屋，棚digitalise v. 使数字化whistle n. 啸声forage v. 搜寻(食物) prey n. 被捕食的动物gunshot n. 射击声groan n. 呻吟，叹息pulse n. 脉冲stun v. 击昏注释:1.

今年的职称英语考试新增了文章，也出现了一个很有趣的现象，理工卫生综合的新增文章都是补全短文，都是新增了5篇文章，而且内容也一样。

了“Common Questions about Dreams”这篇补全短文，这是综合C,理工C以及卫生C的新增文章，供大家学习。

Common Questions about DreamsDoes everyone dream?Yes. Research shows that we all dream. We have our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep, the brain is very active. The eyes move quickly back and forth1 under the lids, and the large muscles of the body are relaxed. REM sleep ours every 90-100 minutes, three to four times a night, and it lasts longer as the night goes on. 1 We dream at other times during the night, too, but those dreams are less vivid.Do people remember their dreams?A few people remember their dreams. However, most people forget nearly everything that happened during the night —dreams, thoughts, and the short periods of time when they were awake. 2 It seems that the memory of the dream is not totally lost, but for some reason it is very hard to bring itback2. If you want to remember your dream，the best thing to do is to write it down as soon as you wake up.Are dreams in color?Most dreams are in color. However, people may not be aware of it for two reasons ：They don’t usually remember the d etails of their dreams, or they don’t notice the color because it is such a natural part of our lives. 3Do dreams have meaning?Scientists continue to debate this issue.3 4 Some people use dreams to help them learn more about their feelings, thoughts, behavior, motives, and values. Others find that dreams can help them solve problems. It’s also true that artists, writers, and scientists often get creative ideas from dreams.How can I learn to understand my dreams?The most important thing to remember is that your dreams are personal. The people, actions, and situations in your dreams reflect your experience, your thoughts, and your feelings. Some dream experts believe that there are certain types of dreams that many people have，even if they e from different cultures or time periods. Usually, however, the same dream will have different meanings for different people. For example, an elephant in a dream may mean one thing to a zookeeper and something very different to a child whosefavorite toy is a stuffed elephant. 5 Then look for links between your dreams and what is happening in your daily life. If you think hard and you are patient, perhaps the meaning of your dreams will bee clearer to you.词汇：vivid /'vivid/ adj. 清晰的，生动的，逼真的lid /lid/ n. 眼睑(=eyelid)motive /m?utiv/n. 动机stuffed /st?ft/adj. 填充的，塞满了的注释：1. back and forth：来回地，反复地。

2018年职称英语考试理工类B级练习阅读理解（2）职称英语理工BInvisibility RingScientists can"t yet make an invisibility cloak1 like the one that Harry Potter2 uses.But,for the first time,they’ve constructed a simple cloaking device that makes itself and somethingplaced inside it invisible to microwaves.When a person "sees" an object,his or her eye senses many different waves of visiblelight as they bounce off the object.The eye and brain then work together to organize thesesensations and reconstruct the object"s original shape. So,to make an object invisible,scientists have to keep waves from bouncing off it.And they have to make sure the objectcasts no shadow.Otherwise,the absence of reflected light on one side would give the obiectaway.Invisibility isn"t possible yet with waves of light that the human eye can see.But it is nowpossible with microwaves.Like visible light,microwaves are a form of radiant energy.Theyare part of the electromagic spectrum,which also includes radiowaves,infrared light,ultraviolet rays,X rays,and gamma rays.The wavelengths of microwaves are shorter thanthose of radio waves but longer than those of visible light.The scientists" new "invisibility device" is the size of a drink coaster and shaped like aring.The ring is made of a special material with unusual ability.When microwaves strike thering,very few bounce off it.Instead,they pass through the ring,which bends the waves allthe way around until they reach the opposite side.The waves then return to their originalpaths.To a detector set up to receive microwaves on the other side of the ring,it looks as if thewaves never changed their paths as if there were no object in the way！ So,the ring is effectively invisible.When the researchers put a small cdpper loop inside the ring,it,too,is nearly invisible. However,the cloaking device and anything inside it do cast a pale shadow.And the deviceworks only for microwaves,not for visible light or any kind of electromagic radiation.So,Harry Potter"s invisibility cloak doesn’t have any real petition yet.词汇：invisibility/invizE5biliti/n.看不见,无形spectrum/5spektrEm/n.光谱cloak/klEuk/斗篷,披风 infrared/5infrE5red/adj.红外线的microwave/5maikrEuweiv/n.微波 ultraviolet ray 紫外线reconstruct/5ri：kEn5strQkt/v.重建 gamma ray 伽马射线radiant/5reidjEnt/adj.辐射的 wavelength/5weivleNW/n.波长electromagic/IlektrEJ5mA^nItIk/adj.电磁的coaster/5kEustE （r）/n.托盘,垫子练习：1.Harry Potter is mentioned in the passage,because scientistsAcan now make an invisible cloak of the same kind as he uses.Btry to make an invisible cloak of the same kind as he uses.Ctry to invent a device Similar in idea to the invisible cloak he uses.Dknow that it is possible to make an invisible cloak of the same kind.2.What is true of microwaves？ATheir wavelengths are shorter than those of visible light.

*第三十四篇Batteries Built by VirusesWhat do chicken pox，the common cold, the flu，and AIDS have in common? They’re all disease caused by viruses，tiny microorganisms that can pass from person to person．It's no wonder1 that when most people think about viruses, finding ways to steer clear of2 viruses is what's on people's minds．b5E2RGbCAPNot everyone runs from the tiny disease carriers, though3．In Cambridge, Massachusetts4, scientists have discovered that some viruses can be helpful in an unusual way．They are putting viruses to work, teaching them tobuild some of the world's smallest rechargeable batteries．p1EanqFDPwViruses and batteries may seem like an unusual pair，but they're not so strange for engineer Angela Belcher，who first came up with5 the idea．At the Massachusetts Institute of Technology (MIT> in Cambridge, she and her collaborators bring together different areas of science in new ways．In the case of the virus-built batteries, the scientists combine what they know about biology, technology and production techniques．DXDiTa9E3dBelcher's team includes Paula Hammond，who helps put together the tiny batteries, and Yet-Ming Chiang，an expert on how to store energy in the form of a battery．“We’re working on things we traditionally don’t associate with nature．” says Hammond．RTCrpUDGiTMany batteries are already pretty small．You can hold A．C and D batteries6 in your hand．The coin—like batteries that power watches are often smaller than a penny．However，every year，new electronic devices like personal music players or cell phones get smaller than the year before．As these devices shrink, ordinary batteries won't be small enough to fit inside．5PCzVD7HxAThe ideal battery will store a lot of energy in a small package．Right now，Belcher's model battery，a metallic disk completely built by viruses，looks like a regular watch battery．But inside，its components are very small—so tiny you can only see them with a powerful microscope．jLBHrnAILgHow small are these battery parts? To get some idea of the size，pluck one hair from your head．Place your hair on a piece of white paper and try to see how wide your hair is—pretty thin，right?

阅读判断：第11篇：Bill Gates: Unleashing Your Creativity（A级）I've always been an optimist and I suppose it is rooted in my belief that the power of creativity and intelligence can make the word a better place.For as long as I can remember, I've loved learning new things and solving problems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a clunky old teletype machine and it could barely do anything compared to the computers we have today. But it changed my life.When my friend Paul Allen and I started Microsoft 30 years ago, we had a vision of "a computer on every desk and in every home", which probably sounded a little too optimistic at a time when most computers were the size of refrigerators. But we believed that personal computers would change the world. And they have.And after 30 years, I'm still as inspired by computers as I was back in seventh grade.I believe that computers are the most incredible tool we can use to feed our curiosity and inventiveness -- to help us solve problems that even the smartest people couldn't solve on their own.Computers have transformed how we learn, giving kids everywhere a window into all of the world's knowledge. They're helping us build communities around the things we care about and to stay close to the people who are important to us, no matter where they are.Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it "tap-dancing to Work". My job at Microsoft is as challenging as ever, but what makes me "tap-danceing to work" is when we show people something new, like a computer that can recognize your handwriting or your speech, or one that can store a lifetime's worth of photos, and they say, "I didn't know you could do that with a PC5 !"But for all the cool things that a person can do with a PC, there are lots of other ways we can put our creativity and intelligence to work to improve our world6. There are still far too many people in the world whose most basic needs go unmet7. Every year, for example, millions of people die from diseases that are easy to prevent or treat in the developed world.I believe that my own good fortune brings with it a responsibility to give back to the world. My wife, Melinda, and I have committed to improving health and education in a way that can help as many people as possible.As a father, I believe that the death of a child in Africa is no less poignant or tragic than9 the death of a child anywhere else, and that it doesn't take much to make an immense difference in these children's lives.I'm still very much an optimist, and I believe that progress on even the world's toughest problems is possible -- and it's happening every day. We're seeing new drugs for deadly diseases, new diagnostic tools, and new attention paid to the health problems in the developing world.I'm excited by the possibilities I see for medicine, for education and, of course, for technology. And I believe that through our natural inventiveness, creativity and willingness to solve tough problems, we're going to make some amazing achievements in all these areas in my lifetime.比尔·盖茨：发挥你的创造力我一直是个乐观主义者，我想这是因为我深信创造力和智慧能使世界变得更美好。

第六篇不要太在意睡眠我们每个人的大脑里都有一个像我们床边的闹钟一样的生物钟。

人脑里的生物钟24小时走一圈，这一圈也就是一次完整的昼夜节律，正是这个节律决定了我们吃饭、睡觉和起床的时间。

青春期时，人的生物钟在定时方面会发生变化，生物钟会提前。

这时，青少年会比以前睡得晚，所以当你妈妈告诉你该睡觉时，你的生物钟可能会让你多推迟几小时，并且电脑或电视光线可能会导致你熬夜到更晚。

生物钟的这种变化对青少年说是正常的，但熬夜到太晚会打乱你生物钟与昼夜时间循环之间的平衡，这样就会带来一些问题，例如：早晨很难按时起床。

位于美国罗得州布郎大学睡眠方面的研究员Mary Carskadon说：“当青少年睡眠不足时会打不起精神，这将影响到他们心情、学习和思考问题的状态。

”其实生物钟与闹钟一样，也是可调的，事实上，生物钟每天都在进行着自我调节，其方式就是通过你眼睛接收到光线的变化。

很早之前，科学家就知道了昼夜光线强弱的变化对生物钟调节起到了重要的作用，长久以来，研究者们认为眼睛所接受到的平衡生物钟的光信号同样作用于人类的视觉系统。

但最近几年的研究发现，人类眼睛有两个感光系统，一个是视觉系统，而另一个是感知昼夜的系统。

第十九篇石墨烯的超强力量当今重大科学技术均以“微型”来呈现，新手机和个人电脑每年都在变得更小，这就意味着电子设备要求内部零件更小，工程师们正在寻求制造这些零件的方法，他们逐渐把目光投向了石墨烯——一种由碳元素构成的超薄材料。

这种材料将改变电子设备的未来。

今年的诺贝尔物理学奖颁发给了来自英国曼切斯特大学的Andre Geim和Kostya Novoselov，以表彰他们对石墨烯的发现。

Novoselov说：“石墨烯不仅小，而且它是世界上所能找到的最薄材料。

”他把它称作“神奇材料”。

石墨烯极薄，25 000片石墨烯叠放在一起才与一张普通白纸一样厚。

如果把一片石墨烯放在手指上，你根本就不会发现，因为你没办法看到它。

碳是宇宙中最多的一种元素，已知的生命体中都含有碳。

职称英语理工类英语阅读理解TV Shows and Long Bus TripsThe beginning of the ride is fortable and somewhat exciting, even if youve traveled that way before. Usually some things have changed---new houses, new buildings, sometimes even a new road. The bus driver has a style of driving and its fun to try to figure it out the first houror so. If the driver is particularly reckless or daring,the ride can be as thrilling as a suspense story. Will the driver pass the truck in time? Will the driver move intothe right or the left-hand lane? After a while, of course, the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But youve got to be careful of what kindof food you eat. Too much salty food can make you verythirsty between stops.1.
