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(音調(diào)).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 was difficult to coordinate(協(xié)調(diào)) our ---his halting(蹣跚),mine impatient-- -and because of that, we didn’t much as we went along. But as we started out, he always said, “you set the pace. I will try to you.”

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血壓) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A study by Karen Allen of the State University of New York measured stress (緊張) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算術(shù)) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed around pets, says Allen, who thinks it may be because pets don't judge.

A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

1.What does the text mainly discuss?

A．Pets’ value in medical research.

B．How pets help people calm down.

C．People's opinions of keeping pets.

D．What pets bring to their owners.

2.We learn from the text that a person with heart disease has a better chance of getting

well if ．

A．he has a pet companion

B．he has less stress of work

C．he often does mental arithmetic

D．he is taken care of by his family

3.According to Allen, why did the people do better with pets around when doing stressful tasks?

A．They have lower blood pressure.

B．They become more patient.

C．They are less nervous.

D．They are in higher spirits.

4.The research mentioned in the last paragraph reports that ．

A．people with dogs did more exercise

B．dogs lost the same weight as people did

C．dogs liked exercise much more than people did

D．people without dogs found the program unhelpful
