One day a professor entered the classroom and told the students they would have an 1 right away. Then the professor 2 the paper. But the students were confused (疑惑) because there was 3 but just a black dot in the center of the paper. The professor noticed their 4 and told them, "I want you to write about what you see there." 5 the students were still confused, they started writing. At the end of the class, the professor took all the answer sheets and started reading the answers in front of the students. All of them 6 the black dot and tried to explain its position and something like that. After the professor finished reading, the whole class was 7 . The students were all worried they would fail the exam.
The professor began to explain, "Don't worry. I am not going to give you grades for this. I just want you to 8 about something. Here everybody focused on the black dot instead of the white paper. It is the same as what we do in our lives. The white paper is just like our whole life and the black dot is the 9 we face every day. We just care too much about things like a lack of money for beautiful clothes, but we 10 see that these problems are very small compared to our whole life. We should remember that there are more valuable things in life."
We all live only once. So we should pay more attention to the truly valuable things.
