A story happened when the telegraph（电报）was the fastest method of long-distance communication. One day, a young man went to an interview for a job as a Morse code operator（莫尔斯电码报务员）.

 Answering the ad in the newspaper, he went to the office address. When he arrived, he walked into a large, busy office filled with noise, including the sound of the telegraph. An office worker asked him to wait until he was called to go into the inner office. Seven other people were already in the waiting area for the interview. The young man sat down and waited with them. After a few minutes, the young man stood up, crossed the room to the door of the inner office, and walked right in. Naturally the other people wondered what was going on.   They were sure that the young man made a mistake and would be refused.

 A few minutes later, however, the boss came out of the inner office with the young man and said to the other people,“Gentlemen,thank you very much for coming, but the young man has got the job.”

The other people were surprised, and one of them said, “Wait a minute. I don't understand. He was the last to come in, and we never even got a chance to be interviewed. Yet he got the job. That's not fair!”

 The boss said, "I'm sorry, but all the time you've been sitting here, the telegraph has been sending out the following message in Mores code: "If you understand this message, then come right in. The job is yours." None of you heard it or understood it. This young man did. The job is this.

    Little Peter is a boy of nine. He began to go to school when he was six, and now he is in Grade Three. He lives not far from the school, but he is often late for class. He likes watching TV in the evening and goes to bed late, so he can't get up on time in the morning.

    This term, Mrs. Black, Peter's aunt, teaches music in Peter's school. She is strict（严格的）with Peter and often tells the boy to obey the school rules and come to school on time. Yesterday morning, Peter got up late. When he hurried(赶紧) to school, it was a quarter past eight. His aunt was waiting for him at the school gate.

    "You are ten minutes late for the first class, Peter," Mrs. Black said angrily. "Why are you often late for class?" "Every time, when I get to the street corner(街道拐角), I always see a guidepost(路标). It says SCHOOL—GO SLOWLY!"

    Mr. Smith is our Chinese teacher. He always asks the same student to answer his questions because he doesn't look at the students at all. Yesterday he questioned Dick three times. Dick was very angry. After class Dick asked me, "What shall I do?" I told (告诉) him a good idea. Now we are having a Chinese class. Mr Smith wants one of us to read the text. "Dick, please read the text." "Dick isn't here today." Dick stands up and says. "Oh, I see, you read it, please."
