Bob and I live in the same building. His room is on the tenth floor, and mine, the ninth. He is kind but careless.

    One day Bob and his friends went to an island for traveling. On the island, they swam, fished and had a picnic. They enjoyed themselves very much. Three days later, they decided to come back by boat. On the way, their boat hit a rock and soon went down. They were all in danger. Luckily, all of them were out of danger with a villager's help. At that time, Bob was quite hungry and tired, so he hoped to get home as soon as possible.

    When he got to the building, it was already midnight. As the lift(电梯）didn't work, Bob had to go upstairs on foot. He stopped by my door and took out his key to open it. Of course, he could not open the door. He tried it again and again, but failed. He became angry and shouted. " What's wrong , my god?" The noise woke me up. I opened the door. I understood at once what was happening and said," You are wrong. It's my room, Bob!"

    "Oh, no, Mike!" Bob shouted, "It's my room. You have opened the door by mistake!"

    Do you like eating chocolate chip cookie？Thanks to Ruth Wakefield, they were invented by accident in 1930.

    Ruth and her husband owned a restaurant called the Toll House. As manager and cook, Ruth kept very busy. One day in 1930, she was making some chocolate butter cookies．It was required that she should melt chocolate into the dough (面团)．However, she found that she had run out of baker's chocolate. So she had to break some semi­sweet chocolate (半甜巧克力) into small pieces and added them to the dough. She hoped these pieces of chocolate to melt.

    After the cookies were baked (烤), to her surprise, the chocolate had not melted into the dough, and her cookies were not chocolate butter cookies. They smelt delicious. They tasted sweet and crispy．

    They were named Toll House cookies after Ruth's restaurant and are the most popular cookies in America today. About seven billion chocolate chip cookies are eaten every year, and nearly half the cookies baked in American homes are chocolate chip cookies.

    Jason Queally is one of the fastest men in the world on bicycle. But do you really call the thing in the picture a bicycle? Well, yes, Jason's human-powered machine. With its two wheels, is, of course, a bicycle.

Every year, a very important human powered bicycle is held in Nevada, USA. The speed of a bike is measured (测定) for only 200-metres, but players take more than a kilometer to get their bikes going fast. Jason Queally's fastest speed for the 200metre race was 103.5 kilometers an hour.

    At this year's race, Jason failed to reach the finishing line. He was speeding along at about 70 kilometers an hour when he began to lose control of his bike. When he tried to slow down, it began to smoke. Soon the inside of his bike was filled with smoke. He couldn't see, and he couldn't breathe. At 70 kilometers an hour, a crash could be very serious. Jason was frightened, but he managed to stop the bike safely. He would repair his bicycle and try again another time to be the world's fastest man on a bike. Better luck next time, Jason.

    Maybe you're surprised that these bikes go so quickly, but is it useful? It could be. Cars are becoming more and more popular, and they are very safe, comfortable and easy to drive, but they also pollute the air in our cities. Scientists and engineers are learning from fast racing bikes how to make human-powered vehicles that might be useful for daily travel.

    When I just moved to Los Angeles（洛杉矶）, I didn't have a car.{#blank#}1{#/blank#}, but I wanted to prove（证明）them wrong.

    I asked my neighbor, Mrs. White, to take me to the bus station in the center of the city, so I could try taking the bus home.{#blank#}2{#/blank#}. When I got there, I went inside and got a bus timetable（时刻表）. I looked at the map and worked out that I needed to take three buses to get home.

    I bought the tickets and went outside to wait at the bus stop for the Number 8 bus. {#blank#}3{#/blank#}. I gave my ticket to the bus driver and took a seat. At the right stop I got off. {#blank#}4{#/blank#}. I waited and waited. A man was also waiting for the same bus. He said that it wasn't unusual for the bus to be late. Half an hour later, it finally came. To make the matter worse, the third bus broke down halfway and the driver had to fix it. {#blank#}5{#/blank#}. So when I finally got home, I was very tired. Maybe getting a car in Los Angeles wasn't such a bad idea!
