Thehistoric fire of London was a serious example of the damage firecan cause. Finally, however, this disaster also positivelyaffected the city.In 1666, the Great Fire of London burned out of control forthree days, destroying most of the central district of the city. The disaster caused a huge amount of damage—around seventy thousand people lost their homes. At the time, there were only about eighty thousand living in the city. There are no accurate records of how many people died in the fire because the worst damage happened in poorneighborhoods. Unfortunately, the government didn’t record the deaths of poor people in those early times.When the fire happened, people in London were already struggling to survive a large plague(瘟疫) outbreak that had begun in 1665. London’s housing troubles were a major cause of the problem. At the time, much of central London consisted of closely packed and poorly made wooden buildings. This created an unhealthy environment because germs travelled freely from home to home. In addition, the buildings were on narrow, dirty streets where people threw their garbage. Rats were attracted by the garbage, and they brought fleas(跳蚤)—the carriers of the plague. Once people caught the plague from flea bites，the disease spread rapidly throughout the city especially in the cramped central district. It was in these terrible conditions that the Great Fire raged through London.Despite the damage, the fire had a positive effect because it destroyed the old, poorly made wooden buildings. It also killed most of the rats and fleas, which slowed the spread of the plague. After the fire, the government rebuilt the damaged areas. Whenever possible, they used brick or stone. Thus, the new houses were much more solid and more difficult for rats to enter. Widened streets and improved garbage collection also helped to stop the disease from spreading from person to person because there was simply more room to walk.【解题导语】本文是一篇说明文。
