五、阅读理解(20 分)
A
Miss Green taught Physics in a London school. Last month she explained to one of her classes about sound,and she decided to test them to see how well 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 Green,because electricity travels faster than sound waves.”
“That's very good,” Miss Green answered. But then one of the girls put up her hand. Miss Green said,“Yes,Betty?”
“I don't think so,” Betty said. “Your sister would hear you earlier because when it's eleven o'clock here,it's six o'clock in Washington.”
( )1. Miss Green was teaching the class ______.
A. to her sound
B. about sound
C. about electricity
D. about telephone
( )2. She wanted to know ______.
A. whether her students could tell which was faster,electricity or sound waves
B. whether her students could hear from 20 metres away
C. whether she could call her sister in Washington
D. whether her sister could hear her in Washington
( )3. The cleverest boy thought that ______.
A. the students would hear Miss Green earlier

答案： 【解析】：
这是一道英语阅读理解题，主要考查学生对文章内容的理解和信息提取能力。文章讲述了格林老师在一所伦敦学校教物理，她给学生讲解了声音的知识后，想测试学生掌握得如何，于是提出了一个问题，询问学生她和远在华盛顿的姐姐通电话时，在20米外街道另一边的学生和姐姐谁会更早听到她说话及原因。题目围绕文章内容设置了三个选择题。
对于第一题，需要从文章中找出格林老师正在教学生关于什么的内容；第二题要明确格林老师想知道什么；第三题要找出最聪明的男孩的想法。
【答案】：
1. B。根据文中“Last month she explained to one of her classes about sound”可知，格林老师正在给学生讲解关于声音的知识，所以选B。
2. A。从格林老师提出的问题“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?”可知，她想知道学生是否能判断出电和声波哪个更快，所以选A。
3. C。由文中“The cleverest boy at once answered,‘Your sister,Miss Green,because electricity travels faster than sound waves.’”可知，最聪明的男孩认为声波比电慢，也就是电比声波快，C选项“sound waves were slower than electricity”符合他的想法，所以选C。
