Jenny and Henry were born on the same day and they look the same. Their father has a taxi and is 
busy all the time. He goes out early in the morning 
but comes back when his children go to bed. He gets
a lot of money but he has no time to concern himself with (关心) their studies.
The two children study in the same class. Jenny works hard at her lessons, but her brother likes
nothing but playing. He is not good at writing compositions.
One day Mrs. Cook told her class to write a composition "My Mother". After supper Jenny wrote
one in her exercise-book and then went to help her mother to do some housework. But Henry went to
play football. When night fell, he came back to watch TV until a TV play was over. And he took off his
clothes and went to bed, he remembered the compositi
on and had to go to the sitting-room again. But he
didn't know how to write it. He thought hard and hard and at last he found a way. He found Jenny's
schoolbag and brought out her exercise-book and copied her composition.
