Ⅴ.书面表达
In the 2008 Beijing Olympic Games Chinese athlete Liu Xiang dropped out of the race due to his foot injury，which led to a heated discussion among people across the country.
According to a survey conducted by Sina Website，over 34% of the people think an athlete should quit the race when injured since health is much more important than a gold medal;while nearly 20% of the netizens believe that an injured athlete should hold on to the end instead of giving up halfway.They regard the sports field as a battlefield in which every athlete should fight for the honor of his or her country in spite of any difficulty.
In my opinion，it was a right choice for Liu Xiang to choose to quit the race.For one thing，nothing is more important than health and sports don't mean sacrificing one's health for a gold medal：for another，after Liu Xiang recovers fully，he still has many chances to realize his dream.
