题目

Miss Gorgers 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 very good," Miss Gorgers answered, but then one of the girls raised her hand, and Miss Gorgers 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." (1)Miss Gorgers was teaching her class . A.how to telephone B.about electricity C.about time zone（时区） D.about sound (2)Miss Gorgers asked 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）herlesson. D.sound waves were slower than electricity. (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. (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. (5)Whose answer do you think is correct according to the law of physics? A.Tom's B.Kate's C.Both A and B D.Neither A nor B

Miss Gorgers 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.

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 very good," Miss Gorgers answered, but then one of the girls raised her hand, and Miss Gorgers 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."

解析

本题为阅读理解题，考查学生对文章细节的理解和逻辑推理能力。文章围绕物理课上关于声音传播的讨论展开，需结合声音传播速度和时区差异两个知识点分析人物观点。解题关键在于：

  1. 明确问题核心：Miss Gorgers提问的目的是测试学生是否理解声音传播的相关知识。
  2. 区分观点差异：Tom的回答基于物理原理（电速快于声速），Kate的回答引入时区差异，需判断其逻辑是否合理。
  3. 物理常识应用：根据实际物理规律判断最终正确答案。

第（1）题

问题：Miss Gorgers在教什么？
解析：文章首句明确提到“Miss Gorgers taught physics... explained to one of her classes about sound”，因此答案为D. about sound。

第（2）题

问题：Miss Gorgers提问的目的是什么？
解析：文中说明“she decided to test them to see how successful she had been in her explanation”，即测试学生是否理解课程内容，答案为C. her students had grasped her lesson。

第（3）题

问题：Tom认为电与声波的速度关系如何？
解析：Tom回答“Because electricity travels faster than sound waves”，直接对应选项B. faster than sound waves。

第（4）题

问题：Kate反对Tom的理由是什么？
解析：Kate指出“when it's 11 o'clock here it's only 8 o'clock in Los Angeles”，即两地时区不同，答案为A. clocks in Los Angeles showed a different time from those in New York。

第（5）题

问题：根据物理规律，谁的答案正确？
解析：

  • Tom的逻辑正确：电话信号通过电传输，速度远快于空气中传播的声波，因此哥哥会先听到。
  • Kate的反驳不成立：时区差异影响的是“时间显示”，但电话信号和声波传播本身不受时区影响，因此Kate的理由与问题无关。
    综上，Tom的答案正确，选A. Tom's。
