学案(三) 高考语篇的价值发掘——提升学科素养
2020·天津7月高考·阅读理解C篇——对接课标主题：科技发展与信息技术创新，科学精神，信息安全
For people who are interested in sound, the field of sound technology is definitely making noise. In the past, sound engineers worked in the back rooms of recording studios, but many of today's sound professionals are sharing their knowledge and experience with professionals in other fields to create new products based on the phenomenon we call sound.
Sound can be used as a weapon. Imagine that a police officer is chasing a thief. The thief tries to escape. And the officer can't let him get away. He pulls out a special device, points it at the suspect, and switches it on. The thief drops to the ground. This new weapon is called a Long Range Acoustic Device (LRAD, 远程定向声波发射器). It produces a deafening sound so painful that it temporarily disables a person. The noise from the LRAD is directed like a ray of light and travels only into the ears of that person, but it is not deadly.
For those who hunger for some peace and quiet, sound can now create silence. Let's say you are at the airport, and the little boy on the seat next to you is humming (哼唱) a short commercial song. He hums it over and over again, and you are about to go crazy. Thanks to the Silence Machine, a British invention, you can get rid of the sound without upsetting the boy or his parents. One may wonder how the Silence Machine works. Well, it functions by analyzing the waves of the incoming sound and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply turn the machine on, point it at the target, and your peace and quiet comes back.
Directed sound is a new technology that allows companies to use sound in much the same way spotlights (聚光灯) are used in the theater. A spotlight lights up only one section of a stage; similarly, a “spotsound” creates a circle of sound in one targeted area. This can be useful for businesses such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer a choice of music along with the various food choices on the menu, allowing customers more control over the atmosphere in which they are dining. Directed sound is also beginning to appear in shopping centers and even at homes.
?好题不厌百回做，每做一次都有新发现
语篇解读：本文是一篇说明文。文章主要介绍了有关声音技术领域的三项发明LRAD(远程定向声波发射器)、Silence Machine(静音机)和Directed sound(定向音响技术)。
1．What could be inferred from Paragraph 2 about the effect of the LRAD
A．It causes temporary hearing loss.
B．It slows down a running man.
C．It makes it easy to identify a suspect.
D．It keeps the suspect from hurting others.
解析：细节理解题。根据第二段倒数第二句可知，远程定向声波发射器会发出一种震耳欲聋的声音，这种声音让人非常痛苦，会使人暂时残疾。由此可知，这种暂时残疾就是暂时性失聪，所以选择A项。
答案：A
2．The Silence Machine is a device specially designed to .
A．silence the people around you
B．remove the sound of commercials
C．block the incoming sound waves
D．stop unwanted sound from affecting you
解析：细节理解题。根据第三段中的“Thanks to the Silence Machine ... comes back.”可知， Silence Machine 能避免不必要的声音影响你，所以选择D项。
答案：D
3．What feature do spotsounds and spotlights share
A．They travel in circles.
B．They clear the atmosphere.
C．They can be transformed into energy.
D．They can be directed onto a specific area.
解析：细节理解题。根据最后一段中的“A spotlight lights ... in one targeted area.”可知， spotsound 和 spotlight 的共同点是它们可以被引导到一个特定的区域，所以选择D项。
答案：D
4．Directed sound can be used for .
A．creative designs of restaurant menus
B．ideal sound effects on the theater stage
C．different choices of music for businesses
D．strict control over any suspicious customer
解析：细节理解题。根据最后一段中的“Restaurants can offer a choice ...they are dining.”可知，Directed sound 可以用于商业为顾客提供不同的音乐，所以选择C项。
答案：C
5．What does the passage focus on
A．How professionals invented sound products.
B．Inventions in the field of sound technology.
C．The growing interest in the study of sound.
D．How sound engineers work in their studios.
解析：主旨大意题。作者在第一段中提出“声音技术”，并在第二、三、四段中介绍了声音技术领域的三种发明。由此可知，文章主要关注的是声音技术领域的发明，所以选择B项。
答案：B
