The famous scientist and thinker, Charles Darwin, was born on February 12, 1809 in England. As a boy，Charles liked to go for walks in the fields and forests. He enjoyed watching nature，and comparing what he saw with everything he had read in science books. He also liked collecting very much. He collected many things: birds，eggs，stones and leaves.

At sixteen Darwin was sent to Edinburgh University to become a doctor. But he was interested in the history of nature.

Then he was sent to study in Cambridge University. There he studied until 1831.

Some time later he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His teacher advised him to go. So when the Beagle left England in December, 1831, Darwin was on it.

The trip lasted almost five years. Darwin saw many new plants and animals. He collected all kinds of plants.

In 1842 Darwin went to live in Kent，and there he continued his studies of change in nature. Darwin understood that plants and animals are not always the same，and that they really change.

By 1859 Darwin had finished his famous book The Origin of Species.

In 1871 Darwin wrote ano ther important book The Theory of Evolution.

Darwin continued his studies in science until he died in 1882.

    In Los Angeles, a waiter served a group of teens. The waiter remembered his experience as a young high school prudent. So he made sure the teens had a pleasant experience at the restaurant. The waiter made sure of it.

    After serving all the teens doing a great job, he was left a tip（小费）,only $3.28. That was hardly enough to buy a drink at Roebucks.

    The waiter went home. And he felt hatred for the students who did not know the value of hard work. They looked down on people like him. Or so he thought.

    After several days, the waiter forgot about it. His life went on as usual. But ten days later, he received a letter from the teens.

    “About a week and a half ago, on October 7, my three friends and I came to eat at this restaurant as our own homecoming celebration. It was an exciting experience for us to be here alone, and it was all new to us. And you were the best waiter we could ask for. You were kind, helpful, and didn't treat us like babies! So I want to say thank you for making our 'groan-up' experience so amazing and fun.

    “I would also like to say sorry on behalf of(代表) my group. Since we were new to all of this, reasonable(合乎情理)，but we had completely forgotten(and didn't know, to be honest) what a tip even was, let alone how much to give. So we emptied our pockets, and all our money added up to $3.28.

    “Having no idea of how small this really was, we left. Later, we realized our mistake and felt terrible. We knew we had to make it right.

    “So together with this letter, you will find the correct 18% tip + extra for simply being amazing. Thank you for your help and patience and also thank you for making our night fun. Thank you!”

    Once upon a time, there was a tree which wanted to become a treasure box. One day, a farmer cut it down and sold it to a carpenter(木匠). The tree was happy because he thought the carpenter would make it into a treasure box.

    To its surprise, the carpenter made it into a feed box for animals. The tree felt very disappointed because that was not its dream. Several years later, the feed box was thrown away. Someone picked it up and placed it into an old temple. The tree forgot its dream little by little.

    One day, a couple came to the temple. The woman gave birth to a baby boy. There wasn't a bed in the temple. So they placed the baby in the feed box. They loved him and regarded him as their treasure. The tree suddenly realized that it became a real "treasure box" at that time.

    Sometimes you may think your dream will not come true. Don't forget your dream. It may be realized in another new way.

    There once lived a rich businessman who had a lazy son. The businessman wanted his son to realize the value of labor.

    One day, he told his son, "Today, I want you to earn something. If you fail, you won't have your meal tonight."

    The boy didn't want to find a job, so he asked his mother for help. She gave him a gold coin. In the evening, when the father asked his son what he had earned, the son showed him the gold coin. The father then asked him to throw it into the well (水井). The son did as he was told.

    The father guessed that the gold was from the boy's mother. The next day, he sent his wife to her parents' home and asked his son to earn something. Since no one helped him, the son had to go to the market to look for a job. A shopkeeper told him that he would pay him a coin if he carried heavy tools for him. The son accepted. As he returned home and gave the coin to his father, he was asked to throw it into the well. The boy cried, "Dad! My body is aching. I'm tired. How are you asking me to throw my hard-carned coin into a well?"

    The businessman smiled. He told his son that one feels pain only when the fruits of labor are wasted. The son realized the value of hard work. He promised not to be lazy any more.

I have invented robots which improve the work of cars. My love of making things began when I was a kid. I really became 1 about inventing after I learned about Thomas Edison.

In Grade Four, we 2 a project by our teacher in class. We had to write to a company and learn about the products. I chose the Thomas A. Edison Company. Soon after,3 company sent me a book about the life of Thomas Edison. 4 excited I was!I enjoyed reading and re- reading about his inventions. I like the recorded sound and the electric light best.

My dad 5 my interest in inventing and encouraged me. He showed me 6 I could turn my ideas into plans and then into new things. Once, I surprised 7 witha model plane I made. Later, we found a similar model plane 8 a store. I learned that different 9 often invent similar things. I also learned that not all great ideas work. Failure is a common part of the inventing.

My dad is always looking for a better way 10 a simple job. His guiding hands, together with my interest in inventing has led me to become an engineer and inventor. Of course, I also thank Thomas Edison. He is my hero.

① Arat Montoya, 36, lives in West Linn, a city in the US. He is from a family of bakers. But he doesn't like making bread. When his father asked him to follow the family tradition, Montoya said, "I'm sorry, Dad. I love dogs. " he said. 

②Montoya spent a few years working at a dog club. After the club closed, Montoya started to offer(提 供) a doggie day care service(服务). He has a" Doggie School Bus" and he works as the driver. The bus runs five days a week and the service is $30 per(每一) dog each day. 

③Montoya's service is pretty nice. Every morning at about 7 a. m. , he drives the school bus to the owners'(主人) houses to pick up the dogs and takes them to" school"—a farm. The dogs are full of excitement because" go to school" means they can play all day. They can run around and play with each other at" school". When" school" finishes, Montoya takes the dogs back home. He also sends some videos and pictures to show the dogs'" school" life to the dogs' owners. 

④ It shows that the doggie day care service is a great business(生意) idea. Montoya loves taking care of those dogs. And the dogs love going to" school". The most important is that the dogs' owners speak highly of Montoya and his business. All of them are happy about this doggie day care service. 

⑤Now, more than 300 owners ask Montoya to take care of their dogs. "I'm the happiest man in the world, " Montoya said. " Doing what I like truly makes me happy. "
