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.

A 10-year-old boy decided to study judo (柔道), although he had lost his left arm in a car accident.

　　The boy began lessons with an old Japanese judo teacher, Mr. Tanaka. The boy was doing well, but his teacher had taught him only one move in three months of training.

　　“Mr. Tanaka,” the boy finally asked, “shouldn’t I be learning more moves？”

　　“This is the only move you know, but this is the only move you’ll ever need to know,” his teacher replied.

　　Several months later, Mr. Tanaka took the boy to his first tournament (锦标赛). The boy won his first three matches, using his one move to win. The boy was now in the finals, and was amazed by his own success.

　　This time, his opponent (对手) was bigger, stronger, and more experienced. The referee (裁判) wanted to stop the match.

　　“No,” the teacher insisted, “let him continue.” Soon, his opponent lowered his guard. At that moment the boy used his move to pin (钉住) him. The boy won the match and became the champion.

　　On the way home, the boy and his teacher reviewed every match. Then the boy asked what was really in his mind.

　　“Mr. Tanaka, how did I win the tournament with only one move？”

　　“You won for two reasons,” his teacher answered. “First, you’ve almost mastered one of the most difficult throws in all of judo. And second, the only defense (防守) for that move is for your opponent to catch your left arm.”

　　The boy’s biggest weakness had become his biggest strength (优点).
