About nine O'clock one evening in May, my roommate Li Ming was lying in bed, trembling with cold and having a cough.His head was aching so intensely that he kept groaning. His forehead felt very hot. We took his temperature. It was 38.5℃.
Without hesitation, I dialed "120". It wasn't long before an ambulance arrived. One roommate brought a blanket for him. Another supported him in the ambulance. Our teacher insisted on giving him some money.
Is he a suspedted SARS patient? Who can tell ? But we did't retreat. When the savage SARS was spreading, people showed fearless spirit regardless of dangers to their own health.This kind of care between persons is the very kind giving, unselfish and priceless devotion or sacrifice.And it is just because of this care that we can have warm families, a happy life and a beautiful world.
