Where is that noise coming from? Not sure? Try living with your eyes closed for a few years.
Blind people are better at locating sounds than people who can see, a new study says, without the benefits of vision the ears seem to work much better.
Previous studies have shown that blind people are better than others at reaching out and touching the sources of sounds that are close by. Researchers from the University of Montreal wanted to see if blind people were also better at locating sounds that are far away.
Twenty-three blind people participated in the study. All had been sightless for at least 20 years. Fourteen of them had lost their vision before age 11. the rest went blind after age 16. The experiment also included 10 people who could see but were wearing blind-folds.
In one task, volunteers had to pick the direction of a sound coming from about 3 meters away. When the sound was in front of them or slightly off center in front, both groups performed equally well.
When sounds came from the side or the back, however, the blind group performed much better than the blindfolded group. The participants who had been blind since childhood did slightly better than those who lost their sight later.
Recognizing the locations of distant sounds can be a matter of life-or-death for blind people, say the researchers. Crossing the street, for instance, is much harder when you can’t see the cars coming.
Still, the researchers were surprised by how well the blind participants did, especially those who went blind after age 16. In another experiment, the scientists also found that parts of the brain that normally deal with visual information became active in locating sound in the people who were blind by age 11. These brain parts didn’t show sound-location activity in the other group of blind people or in the sighted people. The scientists now want to learn more about the working of brains of “late-onset” blind people.
The recent study shows blind people are better at telling __________.
A. The sources of loud sounds. B. the locations of distant sounds
C. the direction of sharp sounds D. the distance of a sound in front of them
Which would be a proper title for the passage?
A. A Research on Blind People B. Where is That Noise Coming from?
C. Hearing Better in the Dark D. What If Living Without Your Eyes?
If people were asked to tell the direction of a sound from the side, who would perform best?
A. Those who are blind. B. Those who have gone blind since children.
C. Those who went blind at age 16. D. Those who are blindfolded.
Which of the following is true according to the passage?
A. Whether to be able to locate the sounds can be of vital importance for the blind.
B. All the volunteers in the experiment are sightless.
C. All the participants did equally well when picking sounds from whatever direction.
D. The later people become blind, the better they can perform in telling the direction of sounds.
What do we know about that parts of brain dealing with visual information are active in locating sounds?
A. This happens in almost all the testers.
B. This only occurs in the people who were blind after age 16.
C. It remains nothing new to the scientists any more.
D. It remains a mystery why it is so.
查看习题详情和答案>>How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words.
The power of words, then, lies in their association—the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase.
Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and vulgar.
What is the origin of language?
A. It is unknown.
B. It is a matter that is unclear.
C. It is a question difficult to answer.

Which of the following about a real poet is NOT true?
A. He is less than a master of words.
B. His style is always charming.
C. His poem can move men to tears.
D. He can express his ideas in words that sing like music.
Where does the real power of the words come from?
A. From the words themselves.
B. From their characteristics.
C. From their peculiarity.
D. From their association.
What is the main idea of the passage?
A. The importance of choosing words.
B. Where the real power of words come from.
C. What great writers are like.

查看习题详情和答案>>A week ago, I read When Money Talks, Listen! by Rich Ezzo. It took only about an hour to read, and that included one trip to the coffee maker and about 10 distractions (分心)from Alex, our cat, who thinks he is the center of the universe.
When I first received a copy, I thought it was a get-rich-quick type of publication. There is nothing wrong with that kind of book, but my mind just doesn’t chase after dreams of wealth. I figure that if God ever wants me to be rich, he knows where to find my purse.
When I began reading When Money Talks, Listen!, I was overjoyed to find that Rich Ezzo isn’t money hungry either. He, too, is hungry for things far more important than money.
I absolutely love this e-book. Why did I wait a week to write the review ? simple. I wanted to see if the impact it had on me could keep up. After reading the last word of the e-book, I totally agreed with the subtitle(副标题)which promised to forever change the way we thought about money. I had so many thoughts running around my mind that I had to install a stop light to stop some while others made their way into the picture. I had a mental traffic jam, which only goes to show how slow the traffic usually is.
It has been a week and the impact is the same. I guarantee this is an e-book you’ll want to read. I urge you to visit the author’s website, MysterMoney. Com, and to download the e-book. You won’t
regret it.

查看习题详情和答案>>How should one invest a sum of money in these clays of inflation (通货膨胀)? Left in a bank it will hardly keep its value, however high the interest rate.Only a brave man, or a very rich one, dares to buy and sell on the Stock Market.Today it seems that one of the best ways to protect your savings, and even increase your wealth is to buy beautiful objects from the past.Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.
I sometimes wonder what a being from another planet might report back about our way of life."The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound.It has a face with twelve black marks and two hands.Men can do nothing without its permission, and it fastens its young round people's wrists so that everywhere men go they are still under its control.This creature is the real master of Earth and men are its slaves."
Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time.Certain men were very clever at measuring the time of clay according to the beating of their own hearts.They were made to stand in a fixed place and every hour or so would shout the time.So it seems that the first clocks were human beings.
However, men quickly found more convenient and reliable ways of telling the time.They learned to use the shadows cast by the sun.They marked the hours on candles, used sand in hour- glasses, and invented water-clocks.Indeed, any serious student of antique should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.
Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home.After all, if you are going to be ruled by time, why not invest in an antique clock and perhaps make a future profit?
According to the passage, collecting antique clocks____.
A.can hardly keep the value of your savings
