(PS：killer means that kind of thing or person that you think that would destory your life or drive you crazy. Like time or jealous or an earthquake, or something like that)
范例1：
I treat natural disaster as the biggest killer for the reason that just few seconds would take thousands and hundreds lives away, tear a great number of families apart. That was the biggest
tragedy in the land of living. Human beings to the Earth like what ants to human beings. We cannot hide from the disaster, cannot run away from it, cannot just close our eyes and pretend we haven’t see it. The only way to do is to screw up your courage, and face it, defeat it even sacrifice your life. The situation in ya’an is terrible. But I hope the people who are suffering the grieved could be braver and feel hopeful for the future, because all of us are backing them up.
Procrastination is one of the biggest killers in my life. I tend to delay doing important things until the last moments. Though I may tell myself that under pressure, I can perform more efficiently, I am actually aware that this is not true all the time. Just before the deadline, I am able to hand the work in, but it may not be the best work that I am capable of doing. I realize I need to constantly remind myself that procrastination is an addiction I need to get rid of, one day at a time.
What is the killer in the life? It is a broad idea. It could be tangible like your enemy and it also could be intangible like jealous or other evil things. I just want to focus on the tangible killer in the life. Although the enemy in life makes everyone annoyed, it cannot deny that the enemy impels you to grow. There is a cliché example: the antelope and the wolf lived in the grasslands but the number of the antelope was little because of the wolf. The hunters killed the wolf but they finally found that despite the number of the antelope increased, they were sicker, fatter than before.
In the human society, Lin Dan should thank to his competitor Li Zongwei. The” killer” Li stimulates Lin to exercise oftener and they make a great progress. .” As the Chinese old proverb going: the heroes cherish the heroes. The “killer” is the people who know you the most otherwise he cannot match to do your “enemy”. The way that putting a competitor beside you is an unbend incentive to drive you. So, to thank your enemy and to appreciate him, you should become stronger.
