Li Yan was awarding the title of “Star Student of the Week” because what she did for our class. On the hot afternoon of last Saturday, Li Yan went to downtown and walked from one store to other, looking for the clothes we would wear in the singing contest. While the rest of us were enjoying our leisure times in cool rooms, she spends the whole afternoon searching for the right clothes. Deeply moved by her, we tried our best and won first prize in the contest. Li Yan is always warm-hearted and care a lot about the class. Beside, she often devotes her spare time to help others. She has set the good example for us.
