A locksmith's apprentice

The old locksmith has repaired locks countless times in his life, and his skills are superb and his fees are reasonable, which is deeply respected by people.

The old locksmith is old. In order not to lose his skill, he chose two young people and prepared to pass on his skill to them.

After a period of time, both young people learned a lot of skills. But only one of them can get the true biography, so the old locksmith decided to give them an exam.

The old locksmith has prepared two safes for two apprentices to open. Whoever spends a short time will win. As a result, it took the first apprentice less than 10 minutes to open the safe, and the second apprentice took half an hour. Everyone thinks that the first apprentice will win.

The old locksmith asked his apprentice, "What's in the safe?" The big disciple's eyes lit up: "Master, there is a lot of money in it, all of which are hundred-dollar bills." Asked the second disciple the same question, the second disciple hesitated for a long time and said, "Master, I didn't see anything in it. No sooner had you asked me to unlock the lock than I opened it. "

The old locksmith was very happy and solemnly declared his second apprentice as his official heir. The master and the apprentice refused to accept it, and everyone was puzzled. The old locksmith said with a smile: "No matter what industry you do, you must keep your word, especially in our line, you must have a higher professional ethics. I accepted my apprentice and trained him to be a skilled locksmith. He must have a lock in his heart and nothing else, turning a blind eye to money. Otherwise, selfish and greedy, it is easy to go to the door or open the safe to withdraw money, and ultimately only harm others and themselves. Everyone who repairs locks must have a lock that cannot be opened. "

1. Read the article and fill in the blanks.

After unlocking the lock, the locksmith asked the two apprentices what their expressions were: the first apprentice showed him _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _. (2 points)

Meeting of mothers, parents and teachers

The first time I attended the parent-teacher conference, the kindergarten teacher said, "Your son has ADHD and can't sit on the bench for three minutes. You'd better take him to the hospital. " On the way home, the son asked her what the teacher said. Her nose hurts, and she almost cried. Because of the 30 children in the class, only he performed worst: only the teacher showed disdain for him. However, she told her son. "The teacher praised you and said that the baby couldn't sit on the bench for a minute. You can sit for three minutes now. Other mothers are envious of their mothers, thinking that only the baby has improved in the class.

That night, her son ate two bowls of rice for the first time and didn't let her feed him.

My son is in primary school. At the parent-teacher meeting, the teacher said, "There are 50 students in the class, and your son got the 49th place in the math exam. We suspect that he is a little mentally retarded. You'd better take him to the hospital for examination. "

On the way back, she shed tears. However, when she got home, she said to her son sitting at the table, "The teacher is full of confidence in you. He said you weren't a stupid kid. As long as you put your heart into it, you will surpass your deskmate. This time, your deskmate ranked 2 1. "

When she said this, she found her son's dim eyes suddenly filled with light, and his depressed face suddenly stretched out. She even found that her son was so docile that she was surprised, as if he had grown up a lot. When I went to school the next day, I went earlier than usual.

The child went to junior high school and held another parent-teacher meeting. She sat in her son's seat, waiting for the teacher to call his name, because at every parent-teacher meeting, her son's name was always called to the ranks of poor students. However, this time it was beyond her expectation, and I didn't hear it until the end. She is not used to it. When I left, I asked the teacher. The teacher told her, "According to your son's current grades, it is a bit dangerous to enter a key high school."

She walked out of the school gate happily and found her son waiting for her. On the way, she touched her son's shoulder and felt an indescribable sweetness in her heart. She told her son, "The class teacher is very satisfied with you. He said that as long as you work hard, you will hopefully be admitted to a key high school. "

Graduated from high school; On the day when the first batch of university admission notices were issued, the school asked her son to go to school. She had a hunch that her son was admitted to Tsinghua, because when she applied, she told her son that she believed he could be admitted to this school.

When her son came back from school, he handed her an express mail with the seal of Tsinghua University Admissions Office. Suddenly, he turned and ran into his room and burst into tears. I cried and said, "Mom, I always knew I was not a smart boy, but you ..."

At this time, she was mixed with sorrow and joy, and could no longer hold back the tears that had condensed in her heart for more than ten years, letting it hit the envelope in her hand.
