Now many students become crazy about collecting cards of heroes of the Three Kingdoms in my school. After one gets a card, he will share it with his friends. Being addicted to it, many students have changed a lot.

　　Some students even play the cards in class so that they have fallen behind in their study. The card is included as a gift in the bag of some food which costs 1.5 yuan. Therefore, to get these cards, many students try their best to get money, even steal money. Sometimes they would rather not eat breakfast than give up buying the food with that card.

　　It is not long before they collect a lot of cards. Without good care the cards can be stolen easily. Thus, many students fight for the cards, which damage their friendship.

　　So dont be fascinated in collecting cards any longer. Study earnestly and become a good host of the new century!
