But, there's another side.
SARS is a reminder of how fragile (脆弱的)life can be. Suddenly, it's not just the old people who are thinking about death. Everyone now realizes there might not always be a tomorrow.
Li Ping, a Senior 3 student in Taiyuan, Shanxi Province, came into contact(接触)with a suspected(疑似)SARS patient in mid-April. He was told to stay at home for at least two weeks. "Watching TV about more and more SARS patients dying, ! never knew that death could be so close. Life is Valuable and I am going to treasure every single day." he said.
SARS teaches people to be grateful, not only for their own lives, but also for others. Doctors and nurses, for example, have to spend all their time with infected(被感染的)patients. As a result, more than 20 percent of SARS cases in China are medical workers.
Liu Yu, a Senior 2 student of Beijing No. 5 Middle School, wants to be a doctor when he grows up. "Although they certainly know of the dangers, doctors and nurses remain bravely dedicated(致力于)to saving people's lives. I was deeply moved by what they have done. I think they are real heroes." he said.
SARS also teaches sympathy(同情). The past few weeks have been terrible for Chinese people. But there are far worse things than SARS in this world, such as war, earthquakes and murders. Think of the Iraqis, who have been living terrible lives for 20 years. Think of how the Americans felt on 9. 11.
And finally, SARS offers the chance to grow. All different types of people and government officials are joining together to cope with this difficult time. When this passes, China and its people, will have learned great lessons.
The story of Li Ping is given in this passage mainly to ______.
A. tell us the hardship of life
B. tell us the fragility of life
C. tell the cruelty of SARS
D. tell us the joy of life
