Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That’s every good,” Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. “Yes, Kate.”
“I disagree,” Kate said. “Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.”
【小题1】 Miss Gogers was teaching her class . A．how to telephone 　B．about electricity 　C．about time zone(时区) 　D．about sound【小题2】Miss Gogers raised this question because she wanted to know whether . A．it was easy to phone to Los Angeles 　B．her student could hear her from 75 feet away C．her students had grasped（理解）her lesson .D．sound waves were slower than electricity【小题3】Tom thought that electricity was . A．slower than sound waves　　B．faster than sound waves C．not so fast as sound waves 　　D．as fast as sound waves【小题4】Kate thought Tom was wrong because . A．clocks in Los Angeles showed a different time from those in New York B．electricity was slower than sound waves C．Tom was not good at physics at all D．Tom’s answer had nothing to do with sound waves【小题5】Whose answer do you think is correct according to the law of physics? A．Tom’sB．Kate’sC．Bath A and BD．Neither A nor BD

(答案→)D 解析：【小题1】根据Last month she explained to one of her classes about sound,可知选D【小题1】根据and she decided to test them to see how successful she had been in her explanation.及下文描述，可知她想知道她的学生是否理解了她的课程，故选C【小题1】根据Tom at once answered, “Your brother. Because electricity travels faster than sound waves.”可知选B【小题1】根据“Your brother would hear you earlier because when it’s 11 o’clock here it’s only 8 o’clock in Los Angeles.”可知选A【小题1】仅仅按照物理学原理汤姆的答案是对的，但是考虑实际情况凯特的答案是正确的，故选A
