When I was about 12 I had an enemy, a girl who liked to point out my shortcomings. Week by week her list grew: I was skinny, I wasn&39;t a good student, I was boyish, I talked too loud, and so on. I put up with her as long as I could. At last, with great anger, I ran to my father in tears. He listened to my outburst quietly. Then he asked, "Are the things she says true or not?" True? I wanted to know how to strike back. What did truth have to do with it?
"Mary, didn&39;t you ever wonder what you are really like? Well, you now have that girl&39;s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said. " I did as he directed and discovered to my surprise that about half the things were true.
Some of them I couldn&39;t change (like being skinny), but a good number I could and suddenly wanted to change. For the first time in my life I got a fairly clear picture of myself. I brought the list back to Daddy. He refused to take it. "That&39;s just for you," he said.
"You know better than anybody else the truth about yourself, once you hear it. But you&39;ve got to learn to listen, not to close your ears in anger or hurt. When something said about you is true you&39;ll know it. You&39;ll find that it will echo inside you. " Daddy&39;s advice has returned to me at many important moments.

B.He didn't know what the girl's enemy had said.

I am one of the many city people who are always saying that given the choice we would prefer to live in the country away from the dirt and noise of a large city. I have managed to convince myself that if it weren't for my job I would immediately head out for the open spaces and go back to nature in some sleepy village buried in the country. But how realistic is the dream?
Cities can be frightening places. The majority of the population lives in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of flats. Children become aggressive and nervous—cooped up at home all day, with nowhere to play; their mothers feel isolated from the rest of the world. Strangely enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on tire same floor in tower blocks don't even say hello to each other.
Country life, on the other hand, differs from this kind of isolated existence in that a sense of community generally binds the inhabitants of small villages together. People have the advantage of knowing that there is always someone to turn to when they need help. But country life has disadvantages too. While it is true that you may be among friends in a village, it is also true that you are cut off from the exciting and important events that take place in cities. There's little possibility of going to a new show or the latest movie. Shopping becomes a major problem, and for anything slightly out of the ordinary you have to go on an expedition to the nearest large town. The city-dweller who leaves for the country is often oppressed by a sense of unbearable stillness and quietness.
What, then, is the answer? The country has the advantage of peace and quiet, but suffers from the disadvantage of being cut off; the city breeds a feeling of isolation, and constant noise batters the senses. But one of its main advantages is that you are at the centre of things; and that life doesn't come to an end at half past nine at night. Some people have found(or rather bought) a compromise between the two: they have expressed their preference for the "quiet life" by leaving the suburbs and moving to villages within commuting distance of large cities. They generally have about as much sensitivity as the plastic flowers they leave behind—they are polluted with strange ideas about change and improvement which they force on to the unwilling original inhabitants of the village.
What then of my dreams of leaning on a cottage gate and murmuring "morning" to the locals as they pass by? I'm keen on the idea, but you see there's my cat, Toby. I'm not at all sure that he would take to all that fresh air and exercise in the long grass. I mean, can you see him mixing with all those hearty males down the farm? No, he would rather have the electric imitation-coal fire any evening.
One of the disadvantages of living in high-rise buildings is that ______.
A.the parents may become violent and difficult to put up with
B.the residents may not have a good view from their windows
C.the residents may become indifferent to their neighbors
D.the children may become too frustrated to be controlled

The controversial Anglo-French supersonic transport plane, the Concorde, had attracted much attention because it is unusually loud. A late-model jumbo 747, for example, creates 100 or more decibels of sound over an eight-square-kilometer area. The Concorde spreads a 100-decibel-plus blanket of noise over some 140 square kilometers. On takeoff, the Concorde sounds like four F-4 fighter jets taking off at once. Its penetrating, low-frequency rumble makes the Concorde "completely distinctive" from other jets.
What bothers noise experts is that plenty of commonplace machines are just as loud as, or even louder than, the Concorde. A sanitation truck can be noisier, and so can a heavy diesel truck pulling away from a stop sign. One expert who has gone out of his way to dramatize the prevalent offensiveness of the city sound-scale is Dr. Thomas H. Fay, director of speech and hearing at Columbia-Presbyterian Medical Center in New York. Dr. Fay took a sound-meter into a New York City subway and proved that an approaching train can be twice as loud as the Concorde.
Since World War Ⅱ, the number of the high-powered noise-makers, from trucks and motorcycles to air conditioners and sirens has increased almost geometrically. It' s no wonder that in many areas of the country, especially in the suburbs, the average sound level has doubled in 20 years. Noise experts estimate that city noises are increasing a half-decibel a year. They found that in 1971 the quietest parts of Los Angeles--thought to be a relatively quiet city--were louder than the loudest districts of New York in 1937.
This passage mainly talks about ______ .
A.the problem of the supersonic transport plane, the Concorde
B.a comparison between the Concorde and other machines
C.the problem of noise
D.noise in the suburbs
