问题 填空题

一次数学测试,满分为100分.测试分数出来后,同桌的李华和吴珊同学把他俩的分数进行计算,李华说:我俩分数的和是160分,吴珊说:我俩分数的差是60分.那么对于下列两个命题:①俩人的说法都是正确的,②至少有一人说错了.真命题是       (填写序号).

答案

题目分析:根据满分为100分,若两人分数的和是160分,即使让其中一人的得分最高是100,另一人的得分是60,则他们分数的差也不会是60分.所以命题②是正确的.

解:若设李华的说法是真命题,则两个人的分数和为160分,

若其中一人拿100分,另一人拿60分,那么他们的分差最大,为100-60=40分<60分.

因此他们两人之中,肯定有人说谎,故本题的真命题是②.

点评:解决问题的关键是读懂题意,仔细分析两个人的语言特征,能够根据满分100分进行分析判断.

One day when some government officials were rebuilding a house, they found a mouse hole in a corner and used smoke to make the mice inside the hole come out. A while later they saw mice running out, one after another,but they saw two mice didn’t run away immediately. It seemed that one was trying to bite(咬) the tail of the other.

Everyone was puzzled, so they came nearer to take a look. They realized that one of the two mice was blind, and the other was trying to allow the blind mouse to bite his tail in order to pull the blind one with him to run away.

During the meal time, they started to talk about the two mice. One serious American said, “I think the relationship between those two mice was that of king and guard.”

A smart Frenchman said, “I think the relationship between them was that of husband and wife.”

A Japanese said, “I think the relationship between them was that of mother and son.”

At that moment, one Chinese asked, “Why did those two mice have a certain relationship?”

Suddenly, they looked back at the Chinese. The American, the Frenchman and the Japanese who had spoken earlier all lowered (低下) their heads in shame, and didn’t answer.

In fact, the great love is not built on friendship or blood relationship. Instead, it is based on no relationship.
