　　Killer bees started in Brazil（巴西）in 195A scientist in St. Paulo（圣保罗）wanted bees to make more honey（蜂蜜）.So he put forty-six African bees with some Brazilian bees. The bees bred（繁殖）and made a new kind of bees. But the new bees were a mistake. They didn't want to make more honey. They wanted to attack. Then, by accident（偶然的）, twenty-six African bees escaped and bred with the Brazilian bees outside.

　　Scientists could not control（控制）the problem. The bees increased fast. They went from Brazil to Venezuela（委内瑞拉）. Then they went to Central America. Now they are in North America. They travel about 390 miles a year. Each group of bees grows four times a year. This means one million new groups every five years.

　　Why are people afraid of killer bees? People are afraid for two reasons. First, the bees sting（叮）many more times than usual bees. Killer bees can sting sixty times a minute nonstop（中途不停地）for two hours. Second, killer bees attack in groups. Four hundred bee stings can kill a person.

　　Already several hundred people are dead. Now killer bees are in Texas（德克萨斯）. In a few years they will reach all over the United States. People can do nothing but wait.
