Miss Alice taught physics in a London school.Last month she was explaining to one of her classes
about sound,and she wanted to test them to see how successful she had been in her work.
She said to them,“Now,I have a sister in Washington.If I was calling her on the telephone,and at the same time you were 20 metres away,and listened to me from the other side of the street,who would hear what I said earlier,my sister or you and why?”
The cleverest boy at once answered,“Your sister,Miss Alice,because electricity travels faster than sound waves.”
“That’s very good,” Miss Alice answered,but then one of the girls put up her hand,and Miss Alice said,“Yes?Betty?” “I disagree.” Betty said,“Your sister could hear you earlier because when it’s eleven o’clock here,it’s only six o’clock in Washington.”
爱丽丝小姐教物理在伦敦上学.上个月,她解释给他的学生关于声音的(知识),她想测试来看看他在工作上如何成功.
她说,“现在,我在华盛顿的一个妹妹.如果我给她打了电话,并在同一时间,你20米远,听我从街的另一边,谁会听我前面所说的,(我的姐姐或你),为什么?“
最聪明的男孩立刻回答,“你的妹妹,爱丽丝小姐,因为电流比声波的传递速度快.”
“很好,”爱丽丝小姐说,然后一个女孩举起了手,爱丽丝小姐说,“是吗?贝蒂?“我不同意.”贝蒂说,“你的妹妹听到你早些时候,因为这里是十一点,这是华盛顿只有六点.”
