Mr. Johnson was an excellent maths teacher. His students would never ____1____ their first class he gave them. He always wrote the numbers 2 and 4 on the blackboard in the first class to his ____2____ students, and asked them, “What is the answer?”
Whenever he asked this question, some of his students said 6 was the ____3____. Some others thought that 2 was more proper and some of them ____4____ 8 as the answer. Moreover, there were still others who were just ____5____ on their seats without a word.
While the students were discussing what the answer was, Mr. Johnson always ____6____ their reply patiently. Finally, he sighed (叹气) and said, “Your ____7____ is useless because none of you focused your attention on the point: What ____8____ the question is asked about. Did I ask you to do anything about the two ____9____? Were they asked to be added, subtracted (减) or to do some other calculations (计算)? If you don’t know the question exactly, how can you give a ____10____ answer?”
So let that be a lesson to all of us: It is important to know what the question is before we try to find out the key.
