Scientific experiments can sometimes go wrong and when they do the results may range from thedisastrous to the troubling.One such experiment took place in South America about fifty years ago.Whether its final consequences will cause serious damage or nothing more than a small trouble still remainsto be seen.The story began in 1956 when an American scientist working in Brazil decided to solve the problem ofincreasing the productivity of that country's bees.He imported a very active type of African bee from Tanzania and mated (交配) it with the more easy-going native variety to produce a new kind of bees.Thenew bees worked harder and produced twice as much honey.It seemed that Professor Kerr,for that wasthe scientist's name,had a total success on his hands.Then things began to go wrong.For some reason as yet unseen,but perhaps as a result of something in their environment,the new bees began to develop extremely attacking personalities.They became bad-tempered and easy to be angry,attacked the native bees and drove them from their living places.But worse was to follow.Having taken over the countryside,the new bees,with their dangerous stings(叮),began to attack its neighbours-cats,dogs,horses,chickens and finally man himself.A long period ofterror began that has so far killed a great number of animals and about 150 human beings.This would have been bad enough if the bees had stayed in Brazil.But now they are on the move,heading northwards in countless millions towards Central and North America,and moving at the alarming speed of 200 miles a year.The countries that lie in their path are naturally worried because it looks as ifnothing can be done to stop them.

科学实验有时会出错,当他们这样做的结果可能范围从thedisastrous到令人不安.一个这样的实验在南美洲大约五十年前发生.无论是其最终的后果将造成严重损害或只是一个小麻烦还是remainsto待观察.故事开始于1956年美国科学家在巴西工作的决定来解决这个问题ofincreasing该国的蜜蜂的生产力.他进口了坦桑尼亚的一个非常活跃的类型的非洲蜜蜂和交配（交配）,它与比较随和原生品种,产生了一种新的蜜蜂.最新的神奇蜜蜂加大了工作力度,并产生两倍的蜂蜜.似乎克尔教授,对于亲昵行为科学家的名字,对他的手中取得圆满成功.然后,事情就开始出问题.出于某种原因,迟迟看不见的,但也许作为东西在他们的环境的结果,新的蜜蜂开始发展极为进攻的个性.他们成了脾气暴躁,容易发怒,攻击本土蜜蜂,并从他们的居住地将其驱逐出境.但更糟的还在后面.经考虑过农村,新蜜蜂,用自己的危险蜇伤（叮） ,开始攻击其邻国 - 猫,狗,马,鸡,最后人类自己. ofterror开始了至今已杀死的动物和大约150人的大量长时间的.这已经够糟糕了,如果蜜蜂已经留在巴西.但现在,他们都在前进,在亿万往中美洲和北美洲航向向北,并在200英里一年惊人的速度移动.的谎言在他们的道路的国家自然着急,因为它看起来ifnothing可以做,以阻止他们.
