A blind baby is doubly handicapped. Not only is it unable to see, but because it cannot receive the visual stimulus(刺激)from its environment that a sighted child does, it is likely to be slow in intellectual development. Now the ten-month old son of Dr. and Mrs. Dennis Daughters is the subject of an unusual psychological experiment designed to prevent a lag(滞后)in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant(婴儿) Dennis is learning to identify the people and objects in the world around him by means of echoes(回声).
The device is an improvement of the “Sonicguide”, an instrument produced by Telesensory Systems,
Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart or guide dog. As adapted for Dennis, it consists of a battery-powered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic(超声的) pulse that creates an 80 degree cone of sound at 6 feet. Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch(音调) and volume(音量) with the size and distance of the object.
The closer an object is, the lower the pitch, and the larger the object, the louder the signal. Hard surfaces produce a sharp ping, while soft ones send back signals with a slightly fuzzy quality. An object slightly to the right of Denny’s sends back a louder sound to his right ear than to the left. Thus , by simply moving his head right and left and up and down, he can not only locate an object but also get some notion of its shape and size, thanks to the varying qualities of sounds reaching his ears as the cone of ultrasound(超声波) passes its edges. Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on her knee and facing her directly, he receives a strong signal in both ears. By turning his head away, he makes her seem to disappear. “From the first time he wore it,” says Mrs. Daughters, “it was like a light going on in his head.”
What remains to be determined is how well the device will help Dennis cope with his surroundings as he begins to walk and venture further into his environment.
Meanwhile, Telesensory, Inc, is working on the development of sonar(声纳) device with somewhat the same sensitivity as Dennis’s for use by school-age children.Dr. and Mrs. Daughters’ research is directed to ________.
A.helping the blind to see and learn as well as others |
B.benefiting the learning process of blind children |
C.solving blind children’s psychological problems |
D.finding out how children develop intellectually |
Infant Dennis becomes the subject of the experiment most probably because ________.
A.he already lags behind the sighted children |
B.he leads a life as normal as any other children |
C.he is at the early stage of the learning process |
D.he has the aid of a sonar-type electronic device |
What can we learn about infant Dennis’ device?
A.Its first design was designed for blind adults. |
B.Its battery is as small as a half-dollar coin. |
C.It is functionally similar to a sane and guide dog. |
D.It has been improved by Telesensory Systems, Inc. |
In the third paragraph, “its edges” refers to ___________ .
A.the edge of an object |

The number of accidents involving pedestrians (行人) wearing headphones is on the rise , a report suggests, causing fresh warning from road safety groups in Britain .
A US-based study found a total of 116 reports of death or injury to pedestrians wearing headphones between 2004 and 2011 , jumping from 16 in 2005 to 47 in 2011 .
Most victims were men (68%) and under the age of 30 (67%) , with around one in ten of all cases (9%) under the age of 18 .Some 89% of the cases occurred in urban areas and more than half (55%) of the victims were struck by trains .
Eighty-one of the 116 accidents (70%) resulted in the person’s death--- even though a warning was sounded in around a third of the cases .
The study concluded , “ The use of headphone may be a safety risk to pedestrians , especially in environments with moving vehicles(cars) . Further research is needed to determine if and how headphone use threatens pedestrian safety .” British road safety groups warned pedestrians to be careful.
Floor Lieshout , director of Youth For Road Safety , said, “ This study shows once more the importance of using all of our senses while we are near traffic . It is important that we find an attractive way to make youth learn about the risks of wearing headphones in traffic .”
Andrew Howard , who is the head of road safety at the Automobile Association , added that some pedestrians can be “so focused in their own little world they forget the world going on around them”.That can include headphone wearers , Howard said, but also people talking on phones.
However , Howard said that more researches needed to be done.
Earlier studies have shown that people wearing headphones or talking on phones can suffer “inattentional blindness” which makes them isolated (孤立) from the world around them .
Ian Harvey , at the charity Civic Voice , said that “ to defeat isolation and to help build a civic(文明的) society , people need to interact(交往) with each other .
He said , “ A basis for any civilized society is communication--- Surfing the web , listening to MP3s , reading blogs or sending e-mail is not interacting with a person; it’s interacting with a machine.
“If people feel socially isolated , they need to have more face-to-face interactions with other human beings and in time , will begin to feel happier and more connected to the world and place they live in .”What does the text mainly discuss ?
A.Recent research on the risks to pedestrians |
B.Safety problems caused by wearing headphones. |
C.The advantages and disadvantages of headphones |
D.Traffic accidents in the United States |
We can learn from the Us-bases study that _________ .
A.most victims died in the accidents |
B.most accidents were caused by cars |
C.most accidents happened in the countryside |
D.most victims are under eighteen |
Howard will probably agree that ____________ .
A.it is safe if you wear headphones in a proper way |
B.people wearing headphones are more likely to go blind |
C.most people wear headphones because of loneliness |
D.it is dangerous to talk on phones while walking |
What Lan Harvey said shows the importance of ___________ .
A.beating isolation | B.communication between people |
C.building a civilized society | D.new technologies |
A portable lung which could help those with breathing problems lead a normal life is being developed by scientists.
The Swansea University scientists say it could take many years before the device(装置) , the size of a spectacle box (眼镜盒) , is available . Lung patients , who have seen how it would work , have welcomed the research.
Its research suggests that one person in every seven in the UK is affected by lung disease---- this equates to approximately 8 million people. As of 6 March 2009, 217 people were on the waiting list for a lung transplant(移植) according to figures by NHS Blood and Transplant .
Now scientists in Swansea are developing a portable artificial lung which could transform (改观) the lives of patients . Researchers claim that in the long term the device could offer an alternative to lung transplant , giving hope to those who suffer from conditions such as emphysema(肺气肿) and cystic fibrosis.
The device mimics the function of a lung---by getting oxygen into and carbon dioxide out of the blood stream . Professor Bill Johns came up with the idea after his son died of Cystic Fibrosis . It is important that we make something that will help people , who instead of being confined (局限) to a wheelchair with an oxygen bottle , can actually walk around and do things for themselves , he said.
Although the research has been welcomed by leading charities(慈善) , caution has also been voiced over the length of time it will take before a portable lung will become available .
“We have to stress that this is several years away from being used , even in a trial stage,” said Chris Mulholland , head of the British Lung Foundation.
Patient Elizabeth Spence from Swansea has been refused the double lung transplant she needs but remains hopeful that one day the new device could save her . “ My body will reject the lungs , so this possibly could be an answer--- another way of getting new lungs without actually having the transplant,” she said.Which of the following about the portable lung would the author agree?
A.It can help a lot in lung transplants |
B.It was once on display |
C.It works differently from the normal one in the body |
D.It’s just like an oxygen bottle. |
It seems as if _______ really matters before the portable lung is put into use.
A.support | B.money | C.time | D.trial |
What’s the author’s attitude towards the portable lung ?
A.Negative. | B.Doubtful. | C.Curious. | D.Objective. |
Which edition can you probably find the passage ?
A.Science. | B.Culture. | C.Economy. | D.Education. |

What is it that makes a house a home ? A home is a place of companionship with people in it who love each other , who are harmonious and closer inside with one another than they are outside with those in the workplace or with classmates at school . A home is a place of companionship that it’s difficult to leave. In a home there is love , sharing and appreciation , and the members help each other .
I have seen families on the street. But if they live , sleep , talk , and eat together , they are a family, even if they are poorly off. You don’t need a roof to make a home. The truly homeless are some of the rich people who build multi-million-dollar houses and are too busy to live in them . The truly homeless are those who have turned their home into a hotel lobby . The parents work. The children do wrong . They don’t talk and eat together every day . They rarely see each other . The truly homeless people are those with babysitters , caretakers , gardeners and maids. Parents are unaware , too busy making money outside the home that they don’t live in . This is another way of looking at the rich and the homeless . Who is to be pitied ?
Control of the computer and the Internet is also important to make a house into a home. If the computer is on all the time , the house turns into an office, even if everyone is at home . Many homes these days are just offices. Human communication has stopped . The computer eats up the time that one should be giving to others within the home . Using the computer moderately gives us time for gentleness , play and communication , not with a screen , but with a human being.The purpose of the first paragraph is to _____________ .
A.tell us that where there is home there is love |
B.tell us what people think home is |

One of Britain’s bravest women told yesterday how she helped to catch suspected police killer David Bieber --- and was thanked with flowers by the police. It was also said that she could be in line for a share of up to £30,000 reward money .
Vicki Brown , 30 , played a very important role in ending the nationwide manhunt . Vicki , who has worked at the Royal Hotel for four years , told of her terrible experience when she had to steal into Bieber’s bedroom and to watch him secretly. Then she waited alone for three hours while armed police prepared to storm the building.
She said : “ I was very nervous . But when I opened the hotel door and saw 20 armed policemen lined up in the car park I was so glad they were there.”
The alarm had been raised because Vicki became suspicious of the guest who checked in at 8 pm the day before New Year’s Eve with little luggage and wearing sunglasses and a hat pulled down over his face. She said : “ He didn’t seem to want to talk too much and make any eye contact.” Vicki, the only employee on duty , called her boss Margaret , 64 , and husband Stan McKale, 65 , who phoned the police at 11 pm.
Officers from Northumbria Police called Vicki at the hotel in Dunston , Gateshead , at about 11:30 pm to make sure that this was the wanted man . Then they kept in touch by phoning Vicki every 15 minutes.
“ It was about ten to two in the morning when the phone went again and a policeman said ‘ Would you go and make yourself known to the armed officers outside ?’ My heart missed a beat .”
Vicki quietly showed eight armed officers through passages and staircases to the top floor room and handed over the key.
“ I realized that my bedroom window overlooks that part of the hotel , so I went to watch . I could not see into the man’s room , but I could see the passage . The police kept shouting at the man to come out with his hands showing . Then suddenly he must have come out because they shouted for him to lie down while he was handcuffed(带上手铐).”Vicki became suspicious of David Bieber because ____________ .
A.he looked very strange |
