“1+1什么时候不等于2?”这是赵本山小品中的一句话.大家知道,艺术的源泉是生活.1980年代,笔者就曾亲身经历过这样一个场面:语文老师与一位自认有一点儿小文采的数学老师斗嘴.引来众人围观.几个回合下来,语文老师没占多少便宜.情急之下,他提出了一个“无赖”话题:“1+1什么时候不等于2?”数学老师想了一想,这个问题还真不好回答,数学老师从来都是教学生1+1=2,1+2=3,哪见过1+1≠2呢?其实,这只是语文老师玩的一个逆向思维的小把戏.他看到数学老师答不出来,便说:“只有在算错的情况下1+1才不等于2嘛,我看你连小学一年级的数学也教不了!”众围观者纷纷赞叹:语文老师是不简单啊……同学们,遇到类似问题,你会怎样回答?当然,我们可能会说一滴水加一滴水还是一滴水,等等.而数学老师如果能够灵活运用自己的专业知识,还是可以圆满回答出这个问题的:“我的可敬的语文老师,1+1=10,1+2=10,1+3=10……你懂吗?”
“1 + 1 when is not equal to 2? ” This is a quote from Zhao Benshan sketches.As we all know, the source of art is life.In the 1980s, I had experienced such a scene: the language teacher and a self Admitted that a little bit of writing math teacher bickering. Attracted crowd onlookers .A few rounds down, language teacher did not account for how much cheaper .In rush, he put forward a “rogue” topic: “1 +1 when Not equal to 2? ”Mathematics teacher thought for a moment, this problem is really bad answer, math teacher has always been teaching students 1 +1 = 2,1 +2 = 3, which have seen 1 + 1 ≠ 2? In fact, this is only a small language teacher to play a reverse thinking trick.He saw the math teacher can not answer, he said: “Only in the wrong case 1 + 1 is not equal to 2 Well, I think you even primary Grade mathematics can not teach! ”“ People onlookers have praised: the language teacher is not easy ah ... ... Students, encountered a similar problem, how would you answer? Of course, we may say a drop of water plus a drop of water or a drop of water , Etc. And if the math teacher is able to flexibly use his or her expertise, it is still possible to answer this question satisfactorily: ”My respectable Language teacher, 1 + 1 = 2 = 10,1 + 10,1 + 3 = 10 ...... you understand me?
