    Li Ping and Liu Ying were classmates and they got alone well with each other. Li Ping did very well in the mid-term examination and felt pride of himself, while Liu Ying fail to pass it. However, Liu Ying made up her mind to catch up. She worked hardly at her lessons than ever before. After school Liu Ying would stay behind to ask his teacher some questions. In the evening she should do her homework carefully and went over her lessons. In a result she made great progress. But Li Ping was quite different. Much more of his spare time spent playing basketball or online games. In the final exam, Liu Ying did more better while Li Ping didn't. Now, it was Li Ping which felt sad this time.
