2013英语四级作文流行病
Epidemics
Epidemics are rampant throughout the whole human history, and they have caused the most devastating impacts on us. Each year, numerous epidemics break out on earth and they have such characteristics as fast spreading and infectious.
Epidemics are harmful in many ways. For one thing, it will make people and animals seriously ill or dead, which is a great loss to the country. For example, the outbreak of SARS once killed lots of people and brought great economic loss to the whole country. For another, there is no cure for many kinds of epidemic diseases. Once we are infected by one of them, it is difficult to be cured.
To avoid the outbreak of some kind of epidemics as possible as we can, we should first change some unhealthy habits or customs. For example, meals served individually should be encouraged, which would reduce the possibility of the spread of germs. On the other hand, the government should learn how to deal with emergencies when an epidemic broke out. I believe as long as we treat and prevent epidemics in the right way, we will finally conquer them.
