Millions of people across the world have pets. Maybe you have one and maybe some of your friends do too. A pet can be special friend, and you may think of him or her as a member of the family. A pet can play with you or just be with you when you don't feel like  (talk).

     (unlucky), pets can't stay with  (we) forever. Like all living things, they will die. Sometimes a pet dies because he or she is too old. Sometimes a pet dies  an accident. Sometimes a pet gets too sick  (live) longer. Even when an animal doctor helps, there are some problems mat just can't  (solve).

    It's a sad thing to know a pet dies. You probably feel lonely  it seems like you lose a friend. You may even feel mad at the vet (兽医) for not being able to make your pet  (well) than it was. Maybe you feel sorry when you remember the fact that sometimes you weren't kind to your pet.

    To some children, it may seem like nobody  (understand) what they are feeling. Someone may say to a girl, "You can get another cat." But she knows she will never have a cat just like the dead one.
