Mr Zhang has a big wallet, but he does not always bring much money with him when he goes out. He likes going shopping, but he seldom buys things for himself. Today is his little daughter's birthday. He wants to buy something for her as a birthday present, so he goes into a shopping mall. He looks here and there, and wants to buy all the nice things he sees for his daughter. But he knows that he cannot buy everything. His little daughter is good at singing and likes music, but she does not know how to use a CD player. A computer is very useful, but she is too young to use a computer. Finally, Mr Zhang sees two lovely teddy bears and decides(决定)to buy them. He gives the teddy bears to his little daughter and she is very happy. She says her father is the best father in the world.
