When the teacher came to the podium, he said, "I'm disappointed. Why? Because there was no 100 in this exam, and many people failed. And there will be a lot of 100 before the exam, because you and I have made a lot of efforts, but? ."

Hearing this, we all bowed our heads like children who did something wrong and silently thought: This exam is not difficult, but why didn't we take the exam 100?

The teacher seemed to see through our minds, so he took out his test paper and threw it on the projection cloth, and began to speak. We all listened attentively to the teacher and said, "1. If the drop of 5 meters is marked as -5 meters, then the rise of 4 meters is marked as-()? Of course, it is recorded as +4 meters. But why don't you bring your unit? "

Hearing this, my hanging heart finally fell down, because the teacher specially told me to take the unit before the exam. During the exam, I saw that there was no unit behind the brackets, so I added the unit.

At this time, the teacher continued to talk until the fifth question was that my face turned from sunny to cloudy.

"According to which figure is this problem solved?" "1.2." The students answered in unison. Then the teacher found out that the first bracket was equal to 12.5 by using the method that the inner product was equal to the outer product. The second bracket is 80 and the third bracket is 4. When the teacher said the score in the next bracket, I regretted hitting my head, because I made a mistake. The known number can be put in the bracket of that score. Especially after listening to it, I regret it.

Later, due to the problem that the computer can't display it, the teacher is going to hand out the test paper. "Wu Manru 93+ 10, Chen Shuting 79." The teachers looked at it one by one, but without my test paper, my heart was pounding, just then the teacher said; My heart slowly calmed down after "Gao Longlong 92".

Get the test paper, go back to your seat, and find that the group should not be wrong, for example; It is wrong to calculate the number of the second sub-question patiently. When drawing the fourth sub-question of the application problem, I forgot to bring the scale and the topic. You know these are all necessary readings every day! Why did you forget to bring your examination paper? While I was reflecting, the bell rang, but I think how short this class is!

After passing this exam, I understand: don't underestimate those ordinary and simple topics, or you will regret it!
