1 . 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.

The first time I saw Suzy Khan, I knew I had to help her. She was really small for her age of 12. The boy in my class often joked about her and laughed their heads off. She would open a book, pretending to read, with tears dropping
All I knew was that she was an orphan (孤儿) from Africa. She

6 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?

9 . A Few Tips for Self-Acceptance
We all want it… to accept and love ourselves. But at times it seems too difficult and too far out of reach.
●
●Forgive yourself for mistakes that you have made. We are often ashamed of our shortcomings, our mistakes and our failures.
●Recognize all of your strengths. Write them down in a journal. Begin to train your brain to look at strength before weakness. List all of your accomplishments and achievements. You have a job, earned your degree, and you got out of bed today.
●Now that you’ve listed your strengths, list your imperfections. Turn the page in your journal. Put into words why you feel unworthy, why you don’t feel good enough. Now, read these words back to yourself.
A.Feeling upset again? |
B.Where do you start? |
C.Nothing is too small to celebrate. |
D.Remember, you are only human. |
E.Set an intention for self-acceptance. |
F.Stop comparing yourself with others. |
G.When does the comparison game start? |
10 . I have a special place in my heart for libraries. I have for as long as I can remember. I was always an enthusiastic reader, sometimes reading up to three books a day as a child. Stories were like air to me and while other kids played ball or went to parties, I lived out adventures through the books I checked out from the library.
My first job was working at the Ukiah Library when I was 16 years old .It was a dream job and I did everything from shelving books to reading to the children for story time.
As I grew older and became a mother, the library took on a new place and an added meaning in my life. I had several children and books were our main source(来源) of entertainment. It was a big deal for us to load up and go to the local library, where my kids could pick out books to read or books they wanted me to read to them.
I always read ,using different voices ,as though I were acting out the stories with my voice and they loved it !It was a special time to bond with my children and it filled them with the wonderment of books .
Now, I see my children taking their children to the library and I love that the excitement of going to the library lives on form generation to generation.
As a novelist, I’ve found a new relationship with libraries. I encourage readers to go to their local library when they can’t afford to purchase a book. I see libraries as a safe haven(避风港) for readers and writers, a bridge that helps put together a reader with a book. Libraries, in their own way, help fight book piracy(盗版行为) and 1 think all writers should support libraries in a significant way when they can. Encourage readers to use the library. Share library announcements on your social media. Frequent them and talk about them when you can.
1. Which word best describes the author’s relationship with books as a child?A.Cooperative. | B.Uneasy. | C.Inseparable. | D.Casual. |
A.Pleasure from working in the library. |
B.Joy of reading passed on in the family. |
C.Wonderment from acting out the stories. |

C.Support libraries. | D.Purchase her novels. |
