In movies and plays, music has an added function1: it not only moves people but also can shock people. Is it true that an ordinary musical instrument can be so powerful?   Our eardrums can withstand sound within 20 to 80 decibels. Once sound exceeds this limit2, even beautiful music will become ear-splitting noise3 and harm health. A strong blast of high sound can twist and break a solid iron sheet. ____1____   The noise from a plane's engine is over 140 decibels. However, the sound of a flute is at most a few decibels. ____2____ It has been proven that people who have worked in an environment with a high sound intensity for a long time suffer varying degrees of heart disease or altered brain waves.   In movies, sometimes the hero can produce a sound that ordinary people can't hear and only those who have the same ability can feel. In nature, there is actually sound that is beyond our hearing. In physics, the sound that exceeds 20,000 Hz is called ultrasonic. ____3____ It does no harm to health.   Sound less than 20 Hz is called infrasonic waves. When we move, the air will vibrate. ____4____ As the frequency of infrasonic waves is close to that of people's internal organs, infrasonic wave may cause resonance in human bodies. As a result, people's vision may weaken and internal organs4 may rupture. However, whether an infrasonic wave can be used as a weapon depends on its intensity5. If its intensity is very low, it won’t damage internal organs or a person's health. ____5____ When wind blows at a force of 3 or 4 over the sea6, it will produce infrasonic waves of several decibels. Only typhoons can produce infrasonic waves of over 100 decibels. At present, scientists can only produce infrasonic weapons in the lab with the help of advanced scientific tools and powerful electric power.   词汇:   eardrum / ' dr m / n.耳膜   infrasonic / , nfr 's n k / adj.次声的   twist / tw st / v.使卷曲,使扭曲   flute / flu t / n.长笛   Hz = hertz n.赫兹   ultrasonic / ltr 's n k / adj.超声波的;n.超声波   withstand / w 'st nd / v.抵挡,经受住   decibel / 'des bel / n.分贝   resonance / 'rez n ns / n.共振   rupture / 'r pt / n.破裂;v.破裂   typhoon / ta 'fu n / n.台风   注释:   1.an added function :另加的一种功能   2.Once sound exceeds this limit:一旦声音超过了这个界限。once是时间状语从句的连词。如:   Once you have learned how to swim, you will love this sport.   一旦你学会了游泳,你会爱上这一运动的。   3.ekr-splitting noise:震耳欲聋的噪声   4.As the frequency of infrasonic waves is close to that of people’s internal organs:由于次声波的频率接近于人体内部器官的频率。that指代前面的frequency。   5.However, whether an infrasonic wave can be used as a Weapon depends on its intensity:但是,次声波能否用作武器取决于次声波的强度。whether an infrasonic wave can be used as a weapon是从句,用作句子的主语。   6.When wind blows at a force of 3 or 4over the sea:当海面上吹起3 ~4级风的时候   练习:   A High sound of 150 decibels can kill a healthy rat.   B The vibration of air can produce infrasonic waves.   C We cannot play high-pitched music with ordinary musical instruments.   D If the intensity of infrasonic wave exceeds 160 decibels, it is extremely harmful.   E Dolphins, whales and bats can make such high-frequency sound.   F Therefore, the sound of ordinary musical instruments cannot harm your health.   2014年职称英语教材理工补全短文   第五篇:The Magic of Sound   答案与题解:   1.A 本段要说明,音量超过80分贝,即使是美妙的音乐,对人体也有害。“空1”前面的句子说:一阵高分贝的强烈的冲击波能使一块铁板扭曲和破裂。“空1”的句子应该与高分贝的声音的危害性有关。选项A的“High sound of 150 decibels can kill a healthy rat”是高分贝声音的危害性的又一个例子。从“空1”位置上隐去的句子必是此句。A是答案。   2.F “空2”前面的句子说,长笛发出的声音强度最多只有几个分贝。选项F提到乐器,和“空2”前面的句子的长笛有联系。再看内容,F的句子是对上一句意思的概括,因此是答案。   3.E “空3”前的句子说超过2万赫兹的声音称为超声波。“空3”后的句子说超声波对人体无害。位于这两个句子之间的“空3”的内容应该与超声波有关。选项E说海豚、鲸鱼和蝙蝠能发出这种高频率的声音。从内容上看,选项E与上下文意思连贯,因此是答案。   4.B “空4”前面的两个句子是”Sound less than 20 Hz is called infrasonic waves. When we move, the air will vibrate”,主题是infrasonic waves。选项B的句子中,有vibration,air和infrasonic waves,它们与上述两个句子的用词重复,说明内容联系十分紧密,而且意思连贯,所以B是答案。   5.D “空5”前面的句子说:如果次声波的强度低,不会伤害人的内部器官或影响人的健康。与上述意思有联系的句子出现在选项D。选项D说:如果次声波的强度超过160分贝,就极为有害。两个句子连在一起,构成一个完整的论述,所以D是答案。   发布“2014年职称英语《理工C》阅读理解原文 ”,更多关于2014职称英语考试答案、职称英语考试真题,请访问网!   特别说明:原文来自教材概括大意第四篇   第四篇:Compact Disks   1 If someone says to you your music CDs don't really hold any music on them, and they only have numbers recorded on them, you may not believe it. In fact, he is right in that sound is actually recorded onto the CDs as special numbers — a digital code.1 The code is pressed onto the CD as bumps on a long spiral track almost five kilometers long. These bumps are an average of 0.5 microns wide.   2 A small laser beam shines onto the bumps as the CD turns. The light is reflected back to a receiver that records how the laser light bounces back. This lets the CD player2 turn the reflected light back into the original code. This means you can hear the original code as music.   3 Digital codes are used with many technologies. E-mail needs these kinds of code numbers. Space probes communicate with their ground station on earth using digital codes. Bar codes are read as digital codes in computer systems. Digital communications with cell phones need digital codes. Weather radios also tune into specific signals using these codes.   4 There are many types of compact disks. One format is called CD-RWs. They can be recorded on and re-recorded onas you would do with a floppy disk3. Another format is the CD-ROM. The technology for recording on these disks is different from other CDs. These CDs have a dye layer that the CD writer can darken or leave clear. The clear and dark spots are the digital code. CD-ROM stands for Compact Disc — Read Only Memory4. This disk is like a "super" floppy disk that can hold lots of information. One CD-ROM can hold the same amount of data as 500 floppy disks. Information is permanently recorded onto it. Computer games and other programs are considered to be CD-ROMs.   5 CDs were first sold to the public in 1982 These CDs still play well and sound fine. Current CDs are expected to last between 70 to 200 years. Of course, you can make sure your CDs last a long time by taking care of them.   6 Science keeps on developing. It may not be many more years before a completely new technology is invented5 and introduced to the public for music recording. In the meantime, there is no doubt you will continue to enjoy listening to your favorite music on CDs6 and playing your favorite computer games on CD-ROMs.   词汇:   bump / b mp/ n.隆块,隆起   spiral / ’spa r l / adj.螺旋形的   probe / pr b/n.探测器   floppy / ’fl p / adj.松软的   floppy disk软盘   format / ’f :m t/ n.格式   dye / da / n.染色   permanently / ’p :m n ntl / adv.永久地   注释:   1.... he is right in that sound is actually recorded onto the CDs as special numbers – a digital code:他说的对,因为实际上声音以特殊的数字形式,即数码,刻录在CD碟片上。in that是“因为”,如:Water is essential in that without it all living things would die.水是基本要素,因为没有水,所有生物都要死亡。   2.CD player:CD播放机   3.as you would do with a floppy disk:就像你使用软磁盘一样   4.CD-ROM stands for Compact Disc – Read Only Memory:CD-ROM是Compact Disc – Read Only Memory这五个词首字母组成的缩写词。   5.It may not be many more years before a completely new technology is invented:过不了几年,说不定又会发明一种全新的技术。many more years是“再过许多年”。   6.“there is no doubt you will continue to enjoy listening to your favorite music on CDs”语法上可以理解为“there is no doubtyou will continue to enjoy listening to your favorite music on CDs”。   练习:   A Digital Code Has Wide Applications   B Floppy Disks Are Outdated   C CDs Are Durable   D CD's Working Principle Is Explained   E. CD-RWs Play Better Than CD-ROMs   F. CDs Are of Many Formats   1. Paragraphs l 2 ________   2.Paragraph 3 ________   3.Paragraph 4 ________   4.Paragraph 5 ________   5.One advantage of CD-RWs is that they can ________ like floppy disks.   6.The author predicts it will not ________ before a new technology is invented for music recording.   7.The laser beam-emitting device and the receiver are considered to ________ of a CD player.   8. Space probes could not ________ without using digital codes.   A shine on bumps   B take many more years   C be the key parts   D restore the original code   E be written on and rewritten on   F keen contact with their ground station efficiently   2014年职称英语教材理工类概括大意与完成句子   第四篇:Compact Disks   答案与题解:   1.D 第一、二段介绍了CD的工作原理。声音以数码的形式刻录到CD碟片上。要想听声音,就得用CD放音机,CD机用激光照射CD,接收器接收和分析从CD反射回来的激光波,还原为原来的数码,再转换为原来的声音。所以,D是答案。   2.A 第三段第一句“Digital codes are used with many technologies.”是主题句。本段其他句子提供例证,即应用领域。作者列举了五个领域:电邮、航天通讯、条码、手机和天气预报。选项A的“Digital code has wide applications”与主题句的意思完全吻合,所以是答案。   3.F 第四段第一句“There are many types of compact disks.”是主题句。本段其他句子列举了两种常用的CD格式:—种是CD-RW,另一种是CD-ROM。选项F的“CDs are of many formats”概括了本段的大意,是答案。   4.C 第五段说的是CD碟片经久耐用,1982年上市的CD碟片至今还能使用,其音质依旧。现在上市的CD,更加耐用,如果使用得当,其寿命可达70 ~ 200年。选项C用了durable予以概括是很恰当的,所以,C是答案。   5.E 第四段中出现CD-RW这个词,介绍了They can be recorded on and re-recorded on。这就是选E的依据。   6.B 第六段能找到与答案有关的句子,即It may not be many more years before a completely new technology is invented and introduced to the public for music recording.   7.C 第二段说到在CD机上还原数码时依靠的是激光发射装置和接收器。由此我们可以推论出激光发射和接收器是CD机的主要部件。所以C是答案。   8.F 第三段第三句“Space probes communicate with their ground station on earth using digital codes.”是选F的依据。
