Mr. Johnson worked in a hospital. Three years ago, when he was sixty-eight, he retired. But a lot of people come to ask him to look them over. He's very busy in the daytime and he wants to have a good rest at night.
Half a year ago a young man moved in the room upstairs. At first he was quiet. The old man was satisfied with him. But now he has several friends. They often came to see him in the evening. They talked loudly, sang and danced. Mr Johnson was unhappy, but he didn't say anything.
It was the young man's birthday yesterday. All his friends came at seven in the evening. They drank too much and made a lot of noise. The old man couldn't fall asleep the whole night. This morning, as soon as he got up, he went upstairs and began to knock at the door. The young man opened for him and asked him to come in.
"Did you hear me beat the ceiling(天花板) last night, young man?" asked Mr Johnson.
"It doesn't matter, sir," said the young man, "I don't mind it. It was very noisy in my room, too."

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we're thankful for turned out to be what they are.

1. Most historians hold that the Chinese invented fireworks in the 9^th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.

2. In May of 1886, a law led John Pemberton, a pharmacist(药剂师), to rewrite the formula(配方) for "Pemberton's French Wine Coca", his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated(碳酸) water. His bookkeeper suggested the name Coca-Cola because he thought the two C's would look good together, which is how what we call Coca-Cola, a world-wide drink came into being.

3. During World WarⅡ, scientists at the University of Birmingham invented the magnetron(磁控管)—an important heat-producing part of the microwave oven. While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels(仁), and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.

When kids at Archisha Singh's school in Loudoun County have a birthday, no parents buy them birthday cakes.
Some schools are worried that children might become fat or eat unhealthy food, so they have banned(禁止) cupcakes altogether.
What do kids do? Birthday kids can donate a book. The headmaster of their school will then read it to their class. The headmaster also hands out birthday certificates(证书), special pencils, and makes sure the kids' names are read out in the school's morning news.
Parents can send stickers(贴纸), pencils and other things to students. None of the things can be food. If a child donates jump ropes or other sports equipment, that child may get his or her name on a certificate. It will then be displayed at school.
Archisha really misses cupcakes, especially those her mother used to make for her kindergarten class, but her school's way is fun, too. "I like both ways," she said.
The headmaster says it's important that the school should be not only teaching, but offering healthy choices to kids. "There is a better life without cupcakes. If you eat a cupcake, then it's gone in two seconds, but a book lasts a lifetime. The sports equipment lasts, and the kids can use it day after day."

It's not easy to be an astronaut's (宇航员) son．Everybody expects you to be special or perfect(完美的)．I often wonder how my father ever had a son like me．I mean he's so special and so good at everything he does．Even in middle school he was class president and captain of the football team．
Well，to be honest，I often dream about being some kind of hero or doing something special—like saving a child from a burning building or discovering（发现）a new star．I was daydreaming （做白日梦）at school one morning when my teacher said there would be a Father's Day writing competition for the whole school．"I hope we have a winner right here in my class．"
When I got home，I started to think about what to write．My father is an astronaut．No，I wouldn't start like that．That was the way others saw him．How did I see my father? Hmm．I saw him sitting with me in the dark when I had a terrible dream．I remembered how he hugged （拥抱）me for hours when my dog Spotty was killed by a car．Yes，these were the things I was going to write．To me，he wasn't just a world-famous astronaut．He was my dad．
My parents and l went to school on Thursday night．There were so many people in the big hall! My dad looked at me，and I shrugged(耸肩)．The third prize was announced(宣布) and it was not me．1 was relieved(释然)and disappointed（失望）at the same time．The second prize was announced．It was me．1 went up to the stage and read what I had written，"My father's son"．When I finished，the people stood up and cheered．I saw my father blowing his nose．Tears were running down my mother's face．Dad cleared his throat（喉咙）and put his hand on my shoulder．"Son，this is the proudest（自豪的）moment of my life．"
It was the proudest moment of my life，too. Maybe I'll never be a great hero or win a Nobel Prize，but it was enough just to be my father's son．
