Bill doesn't do well in Maths. He always looks for excuses(借口)not to have Maths lessons. When he sneezes(打喷嚏),he asks his mother to write a note saying he has a cold. When he has a headache,he asks his mother to take him to the hospital. He spends more time at home than he does at school.
This Tuesday afternoon,Bill takes a bus home. His father is surprised. "You come home early," his father says. "Is school over now?" "No,Dad," Bill says. "School isn't over. I just come home early." "How do you do that?" his father asks him.
"I tell my Maths teacher that I have a new baby brother and I have to come home and help you."
"But your mother has twins," his father says,"a boy and a girl. You have a baby brother and a baby sister."
"Yes. I know,Dad," Bill says. "I'm saving up(储存)my baby sister for next week's Maths lessons."
