灾难(disasters)

　　when it comes to disasters, quite a lot of people believe they will come across sudden disasters in their life. to begin with, natural disasters like earthquakes, flood and draught occur now and then; in addition, diseases like sars, cancer and tumor will attack people unexpectedly; last but not the least, car accidents, plane crashes can’t be ignored as part of disasters.

　　why there are so many disasters? the reasons may go as follows: on one hand, some mysteries about nature are beyond our control and understanding; on another hand, people are careless and can’t foresee what will happen beforehand.

　　from what has been discussed above, i may safely draw the conclusion that disasters can’t be avoided now, but with more knowledge about nature, we’ll certainly reduce the loss brought by them to the smallest degree, so the prospect we are looking forward to will be both bright and encouraging.
