单选题{{B}}TEXT D{{/B}} One source of a poor self-concept is an inaccurate self-perception. Such unrealistic pictures sometimes come from being overly hard on yourself, believing that you're worse than the facts indicate. By learning to take a realistic view of yourself, it will be possible to see whether you have been selling yourself short. Of course, it would be foolish to deny that you could be a better person than you are, but it's also important to recognize your strengths. An unrealistically poor self-concept can also arise from the inaccurate feedback of others. Perhaps you are in an environment where you receive an excessive number of downer messages, many of which are undeserved, and a minimum of upper messages. We've known many housewives, for example' who have returned to college after many years spent in homemaking, where they received virtually no recognition for their intellectual strengths. It's amazing that these women have the courage to come to college at all, so low are their self-concepts; but come they do, and most are excited to find that they are much brighter and more competent intellectually than they suspected. In the same way, workers with overly critical supervisors, children with cruel "friends", and students with unsupportive teachers all tend to have low self-concepts owing to excessively negative feedback. If you fall into this category, it's important to put the unrealistic evaluations you receive to attention and then to seek out more supportive people who will acknowledge your value as well as point out your shortcomings. Doing so is often a quick and sure boost.

单选题The prefix Mach is used to describe supersonic speed. It was named for Ernst Mach (1838-1916), a Czech-born Austrian physicist, who contributed to the study of sound. When twice the speed of sound, it is Mach 2. When it is near but below the speed of sound, its speed can be designated at less than Mach 1. for example, Mach 90. Mach is defined as "the ratio of the velocity of a rocket or a jet to the velocity of sound in the medium being considered." When a plane passes the sound barrier-flying faster than sound travels' listeners in the area hear thunderclaps, but the pilot of the plane does not hear them. Sound is produced by vibrations of an object and is transmitted by alternate increase and decrease in pressure that radiate outward through a material media of molecules--somewhat like waves spreading out on a pond after a rock has been tossed into it. The frequency of sound is determined by the number of times the vibrating waves undulate per second and is measured in cycles per second. The slower the cycle of waves, the lower the frequency. As frequencies increase, the sound is higher in pitch. Sound is audible to human beings only if the frequency falls within a certain range. The human ear is usually not sensitive to frequencies of fewer than 20 vibrations per second, or more than about 20,000 vibrations per second--although this range varies among individuals. Anything at a pitch higher than the human ear can hear is termed ultrasonic. Intensity, or loudness, is the strength of the pressure of these radiating waves and is measured in decibels. The human ear responds to intensity in a range from zero to 120 decibels. Any sound with pressure over 120 decibels is painful to the human ear. The speed of sound is generally placed at 1088 feet per second at sea level at 32 degrees Fahrenheit. It varies in other temperatures and in different media. Sound travels faster in water than in air, and even faster in iron and steel. It travels a mile in 5 seconds in air, it does a mile under water in 1 second, and it travels through iron in 1/3 second. It travels through ice cold vapor at approximately 4,708 feet per second; ice-cold water, 4,938; granite, 12,960; hardwood, 12,620; brick, 11,960, glass. 16,410 to 19,690; silver, 8,658; gold, 5,717.

单选题 George had stolen some money, but the police had caught him and he had been put in prison. Now his trial was about to begin, and he felt sure that he would be found guilty and sent to prison for a long time. Then he discovered that an old friend of his was one of the members of the jury at his trial. Of course, he did not tell anybody, but he managed to see his friend secretly one day. He said to him," Jim, I know that the jury will find me guilty of having stolen the money. I cannot hope to be found not guilty of taking it -- that would be too much to expect. But I should be grateful to you for the rest of my life if you could persuade the other members of the jury to add a strong recommendation for mercy to their statement that they consider me guilty." "Well, George," answered Jim," I shall certainly try to do what I can for you as an old friend, but of course I cannot promise anything. The other eleven people on the jury look terribly strong-minded to me." George said that he would quite understand if Jim was not able to do anything for him and thanked him warmly for agreeing to help. The trial went on, and at last the time came for the jury to decide whether George was guilty or not. It took them five hours, but in the end they found George guilty, with a strong recommendation for mercy. Of course, George was very pleased, but he did not have a chance to see Jim for some time after the trial. At last, however, Jim visited him in prison, and George thanked him warmly and asked him how he had managed, to persuade the other members of the jury to recommend mercy. "Well, George," Jim answered," as I thought, those eleven men were very difficult to persuade, but I managed in the end by tiring them out. Do you know, those fools had all wanted to find you not guilty!"
