Joe was not a good student. He tried hard, but he was not clever enough to understand everything that he was supposed to learn. In fact, whenever Joe had examinations in the past, he had become so nervous that he could not even remember the little he had learned in class. He would sit there, holding his pen tight and scratching his head while other students were busily writing their answers.
Then the time came for the final examination, and Joe spent sleepless nights trying to remember everything he had been taught that year, so that when he went into the examination hall, he was tired and unhappy.
The examination papers were handed out, and Joe looked quickly at his copy. The first question was as difficult as he had feared. He read it through several times, and then slowly began to write, but nothing seemed to come easily. Soon he began to sweat, and the drops fell on the paper.
To try to gain the teacher's sympathy, he drew rings round the drops with his pen and wrote 'MY SWEAT' under them.
The examination finished, and Joe met his friends in the entrance to the hall. They had found the examination easy, they said. "Of course they would!" Joe thought bitterly.
A few weeks later the students' examination papers were returned to them with their grades. Joe's friends had all passed, but Joe's grade was 'E', which meant that he had failed.
Then, when he looked at his paper more carefully, he saw that there were some more marks of water on it, and under them the teacher had written 'MY TEARS.'
長いですが、よろしくお願い致します。

ありがとうございます。 「歌」の場合でも「打った」のほうがいいでしょうか。
