     A man has a cat. He likes her very much. At mealtime the cat sits at the

table with him. The man eats with a knife and a fork, but the cat eats from her own plate. Sometimes, when she finishes her dish, her master(主人)will give her a bit of his food. He likes sharing his meal with her. One day the cat is not at the table at mealtime.

     "Ah! Where is my cat?" asks the man. His wife says, "Can't you eat

without her?"

     So the meal begins without the cat. Before lunch is over, the cat rushes

into the room and jumps into the chair quickly. She has two mice in her

mouth, and before anyone can stop her, she drops(扔下) one into her own

plate, and the other into her master's plate.

     "Dear me!" cries the woman, "A mouse is in your plate!"

     "Hush(安静)!" says her husband. "This shows that she is a nice cat. She

knows what friendship is. She wishes me to share her dinner as I often share(分享) mine with her."
