Amanda has been awarded the Star Student for that she did for our class. Last Saturday, Amanda went to downtown and walked from one store to another, looking for the costumes we would wear in the singing contest. While the rest of us are enjoying our leisure time in the cool and comfortably room, she spent the whole afternoon searching and selecting. Finally, she found the right cloth. Deeply moved by his efforts, we tried our best and won first prize in contest.
Amanda is always warm-hearted and care a lot about the class. Besides, she often devotes her spare time to help others. She has set a good example for us. However, she deserves the honor and we should learn from her.
That's all．Thank you for listening!
