Ever since I was a child, my mouth has caused me trouble. I'm not a bad person; I have a 1 time learning when to keep my mouth closed.

    My mom has told me again and again, "Robert, your constant bad words are hurting me. If you 2 to be this rude, you will get into big trouble."

    It's been a problem at school several times too when teachers have told me something I didn't want to hear. I used to feel it was my duty(职责) to 3 myself.

    One day in English class I began working on my homework until I heard a classmate 4 behind me. It was Nathaniel, who liked doing that as usual.

    At first, I said very 5, "Nathaniel, would you please be quiet?"

    However, Nathaniel continued talking to himself. I quickly 6 "Nathaniel, shut up(闭嘴)!"

    For the next five minutes, we threw hurtful(伤感情的) words back and forth at each other.

    "At least I don't have an ugly lazy eye like you!" I shouted.

    I knew this would make him 7. It would hurt his feelings and shut him up.

    What I said filled him with anger. He tried to 8 over my seat and catch me as he shouted, "That's it! That's it!"

    9 at his reaction(反应), I sat back in my seat. I had never seen Nathaniel act like this before.

    Later on, we were taken to the principal's office. There, Mr. Black, our English teacher, told us to 10 the matter. It wasn't until then that I finally found that 11 I hurt someone physically(身体上), the wounds eventually heal(愈合). But when I hurt them with my 12, sometimes the pain (痛苦) never goes away.

    At the end of the discussion, I said 13 to Nathaniel.

    When I went back to my room, I spent some time praying(祈祷). I began to 14 how often what I said hurt others. But I believe that as I keep praying and asking God to help me, he'll tell me when to keep my 15 closed.

They had dreamed that their son could get a good1and live a better life. However, to Johnnie, school lessons seemed like a wall that was impossible to go through.

    One day when he was in Grade 11, Johnnie went2the school psychologist's(心 理学家的) office to ask for help.

    "Johnnie, I've been studying your marks of all the tests at school. I've made a3study of them," said the psychologist.

    "I've been trying hard," Johnnie was about to4.

    The psychologist put his hand on the boy's shoulder, "People have different kinds of talents, Johnnie. There are painters who are5able to learn math, and engineers who can't sing on key. Some day you will find6you are good at, and when you do, you will make your parents and all of us very7you."

    Johnnie didn't go to university. He found a job working in the gardens around the town. Soon8amazing happened. His customers began to notice that Johnie had what they called a" green thumb" The plants he9grew, and the roses blossomed(开花). People started to accept his10for gardening， because he had an eye for color and light.

That afternoon as soon as he got the permission(许可), he started the work,12he couldn't afford all the tools or the plants that were13. People gave him young trees, rose-bushes, benches and many other things. Before long, it had become a beautiful little14.
