Donald
was not very good at Maths. He couldn't understand the teacher's explanations. Even
when the teacher explained something a second time, Donald still couldn't
understand it.
"Never
mind," Donald told himself. "I'm quite good at other subjects. I'll
cheat (作弊) in the Maths exam to get
a good grade (分数), and then I won't be in trouble."
"I'll
sit next to the boy who does best in Maths," he thought, "and copy
down his answers."
The
day of the exam came, and Donald sat next to Tommy, who was always at the top
of the class in Maths. Donald carefully copied Tommy's answers onto his own
exam paper. At the end of the exam, the teacher collected the papers and graded
them in time.
Then
she said, "Well, boys and girls, I've decided to give a prize to the
student who got the highest grade. It's difficult for me to decide who I'll
give the prize to, however, because two students, Donald and Tommy, got the
same grade."
"Let
them share it," one of the other students said.
"I've
thought about that," the teacher said," but I've decided to give the
prize to one of them."
The
students were surprised when they heard this. They said, "That's not fair.
They got the same grade."
"That's
true," the teacher said. "However, Tommy's answer to Question 18 was 'I
don't know' while Donald's was 'Neither do I'."
