Seeing with Sound

According to a British news report,some blind people may finally get a chance to “see”. 1.Dr. Peter Meijer,a scientist at Philips Research Laboratories in the Netherlands,has developed a new system called the vOICe.The three middle letters in vOICe stand for “Oh,I see.” Meijer’s groundbreaking technology may change the lives of visually impaired people all over the world.

A wearable setup of vOICe system consists of a head-mounted camera,stereo headphones and a notebook PC. The system translates visual images from a camera into complex sounds.2.

The program is based on the theory that people can hear certain sounds and learn to translate them into meaningful mental images. Everything has its own unique sound.3.The height of an object or person could be determined by pitch(音调).And a built-in color identifier speaks out color names when it is turned on. What the vOICe users have to learn is which sound goes with which object. Meijer says that he is counting on the brain’s ability to adapt.

4.Within two weeks,most people who experiment with the vOICe system are able to identify objects such as walls and doors. They are also able to identify certain situations,including whether the lights in a room are on or off. 5.Meijer thinks that translating will eventually become automatic for many users of the vOICe,bringing a form of vision to them for the very first time.

A. Brighter areas sound louder than darker areas.

B. It then sends these sounds to a person through headphones.

C. However, they are not learning to see with their eyes;they are learning to see with their ears.

D. The vOICe system is aiming to treat blindness by translating images from a camera into audio signals.

E. Meijer supposes that the brain is interested in the information “content”,but not the information “carrier”.

F. To evaluate the new system’s effectiveness, a number of visually impaired people were chosen to test the v0ICe.

G. Over time, some users have even learned to “watch” television or “recognize” the outlines of buildings as they walk.

I am an English dictionary. I can still remember the day my ex-owner bought me. He had stood in front of the shelf for around half an hour before finally picking me. Originally, he chose my neighbor. But because she had some ink on the cover, he put her down and chose me instead.

I may sound arrogant (傲慢的) . But please forgive me. I am so proud of my vocabulary. With 100,000 entries and 300,000 examples, I think no scholar can be more knowledgeable than me. My only weakness is that I can’t speak. But that is not my fault. I was not designed to speak in the first place. My ex-owner was supposed to read the phonetic symbols (音标) clearly printed beside each word, which were also my selling point. I should have been respected but have ended up lying next to a piece of used toilet paper inside the rubbish bin.

It is all because of the electronic dictionary. He is the bad guy because he takes advantage of my one weakness. And I just don’t understand why he can be so slim. He also has about 100,000entries but 450,000 examples! But I know this was not the reason why my ex-owner was attracted, for he was not a very diligent (勤奋的) student and seldom read the examples listed. The main reason was that the bad guy had so many games in him. My ex-owner always pretended to be working hard while actually he was playing games.

My ex-owner put me on his bookshelf because of my awesome English name “Advanced English Dictionary”. He wanted people to think that he was an advanced learner. I wanted to tell him that it would be better if he hid the comic books standing next to me. But, you know, I can’t speak. I stood there for years. I was so bored. So I talked to the comic book next to me. Under normal circumstances, I wouldn’t have talked to him because I was educated and he was not. But who else could I choose? He told me that my ex-owner had read him once only and then put him there. I was upset because he had never read me from page one to page 1,000. Was I not a better book than the comic book? I wanted to challenge his honesty but before I did so, he was thrown away.

I give up. My pages are absorbing waste water. There is no way people will use me again. Suddenly, I want to talk to the comic book. Would he talk to me if we met?

1.Why does the dictionary think that the electronic dictionary is the “bad guy”?

A. I t contains more words and examples.

B. It can actually pronounce the words.

C. It has a smaller size.

D. It has many games.

2.The dictionary thinks that its ex-owner put it on the bookshelf because he ______.

A. thought that it could match the comic books

B. wanted his friends to study English

C. just wanted to show off

D. had to use it sometimes

3.What was the dictionary’s attitude toward the comic book standing next to it?

A. It wanted to make friends with him.

B. It respected him.

C. It envied him.

D. It hated him.

4. Which of the following is the best title for the text?

A. A Dictionary Is Replaced with an Electronic One

B. Students Seldom Use Dictionaries

How to Improve Eyesight Naturally

Eyes are important for everybody. You must take care and try everything in your hand to keep them in good condition. Here are some of the tips to improve your eyesight naturally.

1. Strain is known to be a factor in many health conditions and eyestrain(眼疲劳) is no exception. Try meditation, yoga or other methods of stress relief to improve your vision and overall health.

Sit upright in a comfortable chair. 2. Cup your hands so that there is no pressure on your eyes. Let your fingers rest across your forehead. There should be no light entering your eyes. Palming(手掌按摩)should be done for a period of 5 to 10 minutes to start. Palming should be relaxing. It may help to do palming in a darkened room.

3. It will unpleasantly affect your eyesight, which affects the eyes by producing a larger amount of insulin (胰岛素) in the blood. Therefore you shouldn’t be having much fruit juice or something that contains a lot of sugar.

Blink as fast as you can for a few seconds then close your eyes tightly, open and repeat. Do this exercise 3 to 4 times daily.

Foods that are high in fiber, vitamin C, D and beta carotene as well as other vitamins and minerals can help improve your vision. Here are a few foods that can be beneficial to good vision: carrots, eggs, blueberries, spinach, kale, grapes, and fresh garlic.
