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.

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。

完形填空
Animal’s “Sixth Sense”
A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa. Wild animals, 1 , seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that1 they possess a “sixth sense” for 2 , experts said.
Sri Lankan wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island’s coast clearly 3 wild beasts, with no dead animals found.
“No elephants arc dead, not 4 a dead rabbit. I think animals can 5 disaster. They have a sixth sense. They know when things are happening,” H. D. Ratnayake, deputy director of Sri Lanka’s Wildlife Department, said about one month after the tsunami attack. The 6 washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka’s biggest wildlife 7 and home to hundreds of wild elephants and several leopards.
“There has been a lot of 8 evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven,” said Matthew van Lierop, an animal behavior 9 at Johannesburg Zoo. “There have been no_10_ studies because you can’t really test it in a lab or field setting2,” he told Reuters. Other authorities concurred with this 11 . “Wildlife seem to be able to pick up certain 12 , especially birds … there are many reports of birds
detecting impending disasters,” said Clive Walker, who has written several books on African wildlife. Animals 13 rely on the known senses such as smell or hearing to avoid danger slid as predators. The notion of an animal “sixth sense” — or 14 other mythical power is an enduring one3 which the
evidence on Sri Lanka’s ravaged coast is likely to add to. The Romans saw owls 15 omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special power or attributes.

答案与题解 :
1. B 第一句说的是海啸造成了巨大的人员伤亡，第二句说的是动物能逃脱海啸的袭击。两句意思相反，所以要用 however以承接上文。
2. C上文说的是：海啸是一种自然灾害，所以“ sixth sense”范围只能是 disasters，不能是 shelters，foods或 water。
3. A 本句继续在对比海啸造成的人员伤亡和动物能逃脱海啸这一现象。答案应该是选项 A (missed)。其他三个选项的词义与上下文都不相配。
4. D从上下文判断，本句的意思应该是：没有大象死亡，甚至连一只野兔或兔子也没有死。“甚至”的英语词是 even。
5. D 全文说的是动物的第六感觉，而 feel(触觉)，see，hear都属于前五个感觉，所以不是正确答案。
6. A 本句说的是海的巨浪将洪水带到离海岸远达 2英里的地方。正确答案应该是 waves。
7. C 从上下文判断，本句的意思应该是： Yala国家公园是斯里兰卡野生动物昀大的保护区，而 birthplaces(出生地)、playground (操场)和 storage(储存)都与上下文表达的意思接不上，因此不是答案。 reserve的意思是“保护区”不是“储备”或“保留”。因此，选项 C是答案。
8. B 下一句说，这些迹象 (evidence)并没有被证实。因此，这些迹象不可能是 scientific的。而 experimental和 chemical的词义与上下文不配合，因此也不是答案。只有 apparent(明显的)与上下文的意思相配。 apparent的迹象还需得到科学的验证。
9. A 在动物园里工作并发表对动物行为的专业性见解的人一定是老师学者 (specialist)。其他的三个选项都不合适。
10. B本段的第一句是说明为什么 evidence没有得到科学验证。原因是科学家无法在实验室或野外进行特定的实验，以验证动物预见灾难的第六感觉。理解了上下文的意思，就知道选 specific是昀合适的。其他三个选项的词义与上下文不符合， additional，especial和 exceptional分别是“额外的”、“特别的”和“例外的”的意思。
11. C concurred with(同意)支配的宾语应该是 view，opinion，judgment这一类词。前面句子说的是某位科学家指出无法验证动物预见灾难的第六感觉的困难所在，其他老师也同意这一看法，所以选 assessment是正确的。
12. D 本句说提动物特别是鸟有捕捉灾难来临前某些征兆的能力。 route (路线)、behavior (行为)和 principle (原则)与上述意思相去甚远，只有 phenomenon是答案。
13. D 根据常识判断，动物是要信赖味觉、听觉等逃避食肉动物的攻击。 Unwillingly(不情愿地)、 occasionally (偶尔)、doubtfully(怀疑地)与上述意思有悖，只有 certainly是合适选项。
14. A 从本句的意思判断，应该是“某种神奇的能力”，所以要选 some。
15. B本句的意思是“将…看成”，而英语的用词是 see … as，所以要选 as。
