　　The Magic of Sound

　　Music is one of the most beautiful forms of artistic expressions ever invented. 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 car-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 organs4, infrasonic wave may cause resonance in human bodies. As a result, people’s vision may weaken and internal organs 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 /5IEdrQm/ n.耳膜 withstand /wiT5stAnd/ v.抵挡，经受住 infrasonic /7infrE5sCnik/ adj.次声(波)的 decibel /5desibel/ n.分贝 twist /twist/ v.使卷曲，使扭曲 resonance /5rezEnEns/ n.共振 flute /flu:t/ n.长笛 rupture /5rQptFE(r)/ n.破裂 v.(使)破裂 Hz = hertz n. 赫兹 typhoon /tai5fu:n/ n.台风ultrasonic /5QltrE5sCnik/ adj.超声波的 n.超声波 注释：

　　1. an added function：另加的一种功能

　　2. Once sound exceeds this limit：一旦声音越过了这个界限。 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. ear-splitting noise：震耳欲聋的噪音

　　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 4 over 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.

　　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昀多只有几个分贝。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。 F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 (“The vibration of air can produce infrasonic waves.”)的句子中，有 vibration， air有和 infrasonic waves，它们与上述两句子的用词重复，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。
