Secondly, we have to learn to cooperate and compete. Last year, when SARS was spreading rapidly in China, scientists all over the world cooperated with each other and prevented the disease from spreading in a short period of time. At the same time, they were also competing against each other to see who could conquer the disease first. By cooperating and competing, the world develops day by day. Therefore, we, the younger generation, must know how to cooperate and compete.
