     Nick is twenty-three and works in a middle school. Two and a half years ago he was ill in hospital and

there he knew a beautiful nurse named Rita. The girl took good care of him and he made friends with her.

They loved each other. About six months later they married.

     Nick likes reading. When he comes home, he always reads some newspaper or books. Rita begins to

cook in the kitchen. And when the meat is roasted (烤), she always tells her husband to cut it in two. Then

they begin to have supper together. After supper they go out for a walk, or they go to the cinema. And they

enjoy themselves. 

    One day Nick planted trees with his students. They climbed up a mountain and worked hard. When he

got home, he felt hungry. His wife roasted a piece of chicken that evening and told him to cut it. This time

he chose a bigger piece of chicken for himself and gave her the smaller one.

     "I remember, dear," Rita said with a smile. "When we married, you always gave me the bigger part. Why

do you give me the smaller one now?"

     Nick felt shy and didn't know what to say. He thought for a while and said, "You cook better now than

before."
