Most people are afraid of bees. Anyone who’s been stung by one quickly learns to avoid bees whenever possible. I learned that lesson when, as a child, I ran into a beehive. Dozens of bees attacked, stinging me all over my body. It was a painful incident, but I was lucky. Those bees weren’t Africanized, or “killer” bees.
Killer bees are extremely aggressive(攻击的). When they become upset, they attack. And just about anything like noises, shiny objects, dark clothes can all cause killer bees to attack. When one killer bee stings a victim, it gives off a chemical. Other bees smell this and go into attack mode. The whole hive will aggressively attack the unfortunate victim. Killer bees will also run their victims for up to a quarter of a mile. Some victims have tried to keep away from the bees by jumping into water. But killer bees will wait for them to come up and then continue their attack.
Killer bees can be found in South America and the southern
The new Africanized bees actually decreased honey production and were very aggressive. Scientists tried to separate the bees, but some of them escaped and began rapidly spreading north. Since then, killer bees have been causing damage to humans, animals and the American honey industry. Over the years, these aggressive killer bees have caused nearly 10,000 people to die.

Farming was once the chief way of life in nearly every country. People cannot live without food, and nearly all their food comes from crops and animals raised on farms. Not many people farm for a living any more, but farming remains the most important work in the world.
Before the nineteenth century, the typical American family lived on a small farm. They raised pigs, cattle, sheep, chickens, and planted corn, fruits, garden vegetables, and wheat. Everyone worked long and hard, but the results were often poor. Families barely harvested enough food for themselves. This situation began to change during the last half of the 1800's and it changed remarkably(明显地) in the next century.
Scientific methods and labor-saving machinery have made farming increasingly productive. The development of improved plant varieties and fertilizers has helped double and even triple the production of some major crops. More scientific animal care and animal raising have helped increase the amount of meat and products that animals produce. At the same time, the use of tractors and other modern farm equipment has sharply reduced the need for farm labor.
As farming has become less important as a way of life in the United States, it has become more important as a source which offers materials to industry. Today's successful farmers are experts not just in agriculture but also in accounting, marketing, and finance. Farms that are not run in a similar way have great difficulty surviving.
