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_________.

A. how to telephone

B. about electricity

C. about time zone(时区)

D. about sound

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 her lesson

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

Answer

1.D

2.C

3.B

4.A

5.A

【解析】

试题分析：本文讲述了Miss Gogers想测试自己所教物理中声音学生掌握的情况。结果Kate和Tom给出了不同的答案，Tom的说法是正确的。

1. 细节题。根据文章第一段第二句前一半Last month she explained to one of her classes about sound可知她正在教学上学习物理中的声音。故D正确。

2. 推理题。根据第一段第二句后一半she decided to test them to see how successful she had been in her explanation可知她要测试她教得怎么样，也就是学生是否掌握了她所教内容。故C正确。

3.B 细节题。根据第二段第二句Because electricity travels faster than sound waves.”可知Tom认为电比声音传播更快。故B正确。

4.A 推理题。根据文章最后一段“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认为是时差的问题，而不是电传播速度的问题。故A正确。

5.A 常识题。电话里的声音传播速度比声音传播速度快是因为电磁波的速度更快，而不是时差的问题。所以Tom的看法是正确的。故A正确。
