Question

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.”

1.Miss Gogers was teaching her class_________.

3.Tom thought that electricity was _________.

A. slower than sound waves

B. faster than sound waves

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

【解析】

試題分析：本文講述了Miss Gogers想測試自己所教物理中聲音學(xué)生掌握的情況。結(jié)果Kate和Tom給出了不同的答案，Tom的說法是正確的。

1. 細(xì)節(jié)題。根據(jù)文章第一段第二句前一半Last month she explained to one of her classes about sound可知她正在教學(xué)上學(xué)習(xí)物理中的聲音。故D正確。

2. 推理題。根據(jù)第一段第二句后一半she decided to test them to see how successful she had been in her explanation可知她要測試她教得怎么樣，也就是學(xué)生是否掌握了她所教內(nèi)容。故C正確。

3.B 細(xì)節(jié)題。根據(jù)第二段第二句Because electricity travels faster than sound waves.”可知Tom認(rèn)為電比聲音傳播更快。故B正確。

4.A 推理題。根據(jù)文章最后一段“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.” 可知Kate認(rèn)為是時(shí)差的問題，而不是電傳播速度的問題。故A正確。

5.A 常識題。電話里的聲音傳播速度比聲音傳播速度快是因?yàn)殡姶挪ǖ乃俣雀�快，而不是時(shí)差的問題。所以Tom的看法是正確的。故A正確。
