问题补充：
Donald was not very good at math. He could not understand the teacher’s explanations(解释). Even when the teacher explained something a second time, Donald still could not understand it. “Never mind,” Donald told himself. “I am quite good at other subjects. I will cheat(作弊)in the math exam, then I won’t be in trouble.”
“I will sit next to the boy who is best at math,” he thought, “and copy down his answers.” The day of the exam came, and Donald sat next to Brain Smith, who always was at the top of the class in math. Donald carefully copied Brian’s answers onto his own exam paper. At the end of the exam, the teacher collected the papers and graded(批改)them. Then she said, “well, boys and girls. I have decided to give a prize to the student who got the highest grade. It’s difficult for me to decide who to give the prize to, however, because two students, Donald and Brian, got the same grade.”
“Let them share it,” one of the other students said.
“I thought about that,” the teacher said, “but I decided to give the prize to Brian.” Donald was angry when he heard this. He stood up and said. “That’s not fair. 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 “Neither do I”.

解析：
试题解析：本文大意：唐纳德数学不太好，听不懂老师的解释，老师再讲一次也听不明白。决定考试时作弊。他的邻座是班里数学最好的。唐纳德仔细地把布来恩的答案抄到他自己的考试卷上。考试结束后，唐纳德和布来恩的分数一样，老师决定把奖品给布来恩，唐纳说这不公平，他来布来恩的分数一样。老师说布来恩的第17题答案是“我不知道，”他的是“我也不知道”。
