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 or 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, “spotsound” creates a circle of sound in on 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.

“They tell me that you’d like to make a statue(塑像) of me-is that correct, Miss Vinnie Ream?”
The deep, gentle voice helped calm the nervous girl. Asking a favor of the President of the United States was no casual matter, especially for a seventeen-year-old girl.
“Yes, sir,” she replied, her dark eyes meeting his. “I wouldn’t have duo ask you, but my teacher, Mr. Mills, says I am ready. I plan to make it in an admirable manner. “
President Lincoln smiled. “Painters, sculptors-they’ve all tried to make the best of this ordinary face, but I’m afraid there’s not much hope. What did you have in mind, Miss Ream? A bust(半身像)?”
Before Vinnie could say yes, the President hurried on, a shade of apology in his voice.
“Of course-I shouldn’t have asked. A full-length pose would be much too big a project for a young woman your size. “
Vinnie’s face turned red. She realized she looked like a child, with her tiny figure. “Small does not mean weak, sir,” she defended herself. “I was born in the country of Wisconsin. I’ve driven teams of horses and carried water. Making a full-length clay(粘土) figure would not exhaust my strength-and that is what I intend to do!”
The President’s eyes, brightened at her show of spirit. “Sorry, madam, I have underestimated you as I didn’t know your background.”
But his smile faded as he rubbed his beard with bony fingers, in thought. “Miss Ream,” he sighed, “I’d like to let you do it, but as you know, we are in the middle of a war. How could I possibly take the time to pose for a sculpture now? I hardly have a minute to myself.”
Vinnie glanced around and noted the size of his office. “I work quickly,” she said. Her voice was soft but confident as she pointed to the corner near the windows. “If I were to bring my clay here and work for three hours every afternoon, I could complete most of the project while you are at your desk.”
The President seemed to consider her idea seriously. He got up and shook Vinnie’s hand warmly, “I’ve heard that you are a talented young woman, and I have found you charming and intelligent as well. I cannot make my decision immediately, but you will hear from me soon.”
The very next day, Vinnie received an invitation from the President.
1.What gave Vinnie confidence to make her request of President Lincoln?
A.Her aggressive personality.
B.Mr. Mills’s encouraging remark.
C.President Lincoln’s gentle voice.

How to Use a Modern Public Library
Has it been a while since your last visit to a public library? If so, you may be surprised to learn that libraries have changed for the better. It’s been years since they were dusty little rooms with books. They have transformed themselves into places where you can develop your love of knowledge meet interesting people, or find out how to start a business.
Check out a book. While libraries still loan out(出借)books, you’ll find it easier to get a copy of whatever you’re looking for, thanks to a cooperative network of area libraries. Via such networks, libraries share their books with each other through the use of delivery vehicles. Once the book you’ve requested is delivered to the nearest branch, they will inform you by e-mail, so you can pick it up.
Check out other items. The library is now a multimedia zone, loaded with information in many formats(载体形式). You can borrow movies on DVDs, music on CDs, and popular magazines. Some libraries even loan out toys and games. If a popular magazine you want isn’t offered and the library keeps a list of such requests, they may bring it in when enough interest is shown.
Join targeted reading groups. Libraries will often hold reading-group sessions targeted to various age groups. Perhaps you’d like to learn a language or improve your English. The library may sponsor a language group you could join. If you have difficulties reading, ask about special reading opportunities. Your library might be able to accommodate you. And you might find it relaxing to bring your small kid to a half-hour Story Time while you sit quietly in a corner with a good book.
Start a business using the help of your local library. If you want to have a business of your own, your local library can become a launch space for it. In library books and computers, you can find information on starting a business. Many libraries will help you with locally supplied information about business management shared through chambers of commerce(商会)and government agencies, and they will offer printing, faxing and database services you need.
