One night, a little before nine o'clock, Dr Johnson was answering a telephone call. He was asked to go and give an operation to a very sick boy at once. The boy was in a small hospital in Glens Falls, sixty miles away from Dr Johnson's city - Albany. The boy had hurt himself in a traffic accident. His wife was in danger, but his family was so poor that they could not pay the doctor anything. After he heard all this, Dr Johnson was driving carefully. He thought that he could get to the hospital before 12 o'clock. A few minutes later, the doctor's car had to stop for a red light at a crossing. Suddenly a man in an old black coat opened the door of the car and got in. "Drive on", he said. "I've got a gun ." "I'm a doctor," said Johnson, "I'm on my way to a hospital to operate on a very sick..." "Don't talk," said the man in the old black coat, "Just drive." A mile out of the town he ordered the doctor to stop the car and get out. Then the man drove on down the road. The doctor stood for a moment in the snow. After half an hour, Dr Johnson found a telephone and called a taxi. At the railway station he learned that the next train to Glens Falls would not leave until 12 o'clock. It was after two o'clock in the morning when the doctor arrived at the hospital in Glens Falls. Miss Clarke, a nurse, was waiting for him. "I did my best," said Dr Johnson. Miss Clarke said, "The boy died an hour ago." They walked into the waiting room. There sat the man in the old black coat, with his head in his hands. "Mr. Shute," said Miss Clarke to the man, "this is Dr Johnson. He had come all the way from Albany to try to save your boy." The man in black would feel _ in the end. A) happy and pleased B) regretful and sad C) worried and angry D) tired and hungry

*Question*
A blind baby is doubly handicapped. Not only is it unable to see, but because it cannot receive the visual stimulus 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 in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant Dennis is learning to identify the people and objects in the world around him by means of echoes . 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 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 and volume 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 passes _ . 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... 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
