Donald was not very good at math.

He could¹ not understand the teacher's explanations².

Even³ when the teacher explained⁴ something a second time, Donald still could not understand it.

"Never mind," Donald told himself⁵. "I'm quite good at other subjects. I'll cheat⁶ in the math exam⁷, then I won't be in trouble⁸." "I'll sit next to the boy who's best at math, he thought⁹, "and copy¹⁰ down his answers."The day of the exam came¹², and Donald sat¹³ next to Brian Smith, who always was at the top of the class in math.

Donald carefully¹⁴ copied¹⁵ Brian's answers on to his own¹¹ exam paper. At the end of the exam, the teacher collected the papers¹⁶ and graded them.

Then she said¹⁷, "Well, boys and girls, I've decided¹⁹ to give a prize²⁰ to the student who got²¹ the highest grade. It's difficult for me to decide¹⁸ who to give the prize to, however²², because two students, Donald and Brian, got the same grade.

"Let them share²³ it," one of the other students said.

"I've thought about that," the teacher said, "but I've decided to give the prize to Brian."Donald was angry when he heard this.

He stood²⁴ up and said, "That's not fair²⁵. I got the same grade as Brian. ""That's true," the teacher said. "However, Brian's answer to Question 18 was 'I don't know'. Yours was 'Neither²⁶ do I'."多纳尔德数学不太好。

他听不懂老师的讲解。

即使解释第二遍，他也听不懂。

“不要紧，”多纳尔德安慰自己，“我别的科目很好。我要在数学考试中作弊，那么我就不会有麻烦了。”

“我将坐在数学最好的同学旁边，”他想，“并抄下他的答案。”

考试那一天到来了，多纳尔德坐在布思·史密斯的旁边。

布恩是班里数学学得最好的学生。

多纳尔德仔细地把布恩的答案抄下来。

考试结束后，老师把卷子收上去，开始判分。

判完后，她说：“好，同学们，我已决定给得最高分的同学奖励。然而我不知该奖励哪一个，因为两个学生，多纳尔德和布恩，都得了一样的分数。”

“让他们两个都得奖励吧，”一个学生说。

“我想过这样办，”老师说，“但我打算奖励布恩。”

多纳尔德听到这话非常生气。

他站起来说：“这不公平。我和他得的分数是一样的。”

“是这样的，”老师说，“然而，布恩的第18题的答案是‘我不知道’。你的是‘我也不知道’。”
