Long long ago, there was no paper in the world. People had to write characters(汉字) in bamboo slips or stones.Then there was a man named Cai Lun who was a Chinese man. He made people use all kinds of things to invent paper. From then on, people can use paper to write on. Paper is a great invention. We always remember the great inventor Cai Lun. Nowadays paper is very useful in our work, study and our life.It really means a lot to human beings

     Maybe everyone likes dogs, and almost everyone likes to read stories about dogs.
　  I have a friend. He has a large police dog named Jack. Police dogs are very clever. Every Sunday afternoon my friend takes Jack for a long walk in the park. Jack likes these long walks very much.
　  One Sunday afternoon a young man came to visit my friend. He stayed a long time. He talked and talked. Soon it was time for my friend to take Jack for his walk. But the visitor still stayed. Jack became very worried. He walked around the room several times and then sat down in front of the visitor and looked at him. But the visitor paid no attention to Jack. He went on talking. At last Jack got angry. He went out of the room and came back a few minutes later. He sat down again in front of the visitor, but this time he took the visitor's hat in his mouth. The visitor saw it and was surprised. He laughed and left.

    There were many plants in a forest. When spring came, a pine tree saw a red rose nearby and said, "What a beautiful flower! I wish I were that lovely. "

    The rose proudly said, "It seems that I am the most beautiful flower in this forest." Then the rose looked at a cactus (仙人掌) and said, "Look at that ugly plant full of thorns（刺）! "

    "What a proud flower!" thought the trees.

    As the days passed, the red rose often looked at the cactus and said bad words about it, like "This plant is useless. How sorry I am to be his neighbor!"

    The cactus never got angry and even tried to advise the rose, saying, "God did not create any form of life without a purpose."

    Spring passed, and the weather became very hot. As there was no rain, the red rose began to wilt（枯萎）.

    One day the rose saw birds put their beaks (喙) into the cactus and then fly away. The red rose asked the pine tree what the birds were doing. The pine tree explained that the birds were getting water from the cactus.

    "The cactus has water?" asked the rose.

    Yes, you can also drink some from it. The birds can bring water to you if you ask the cactus for help. "

    The red rose felt too ashamed to ask for water from the cactus. But finally it did ask for help. The cactus kindly agreed.

    The rose learned a lesson and never judged (评价) anyone by their appearance again.

    Mr. King goes to a dinner party. He is wearing old clothes. He comes into the room. But people in the room don't look at him. They don't ask him to sit at the table.

    Mr. King goes home and puts on his good clothes. He goes back to the party. Everyone in the room stands up and smiles at him. They give him very good food to eat.

    Mr. King takes off his coat, and puts it in the food and says, "Eat, coat!"

    The other people ask, "What are you doing?"

    He answers, "I'm asking my coat to eat the food. When I wear my old clothes, you don't look at me or ask me to sit down. But now you give me very good food. Now I see, you give the food to my clothes, not to me!"

①Almost everyone has a question or two about living in space. What is life really like in space? And what do astronauts do there?

②Astronauts living in space have the same hygiene needs as people do on Earth. They wash their hair, brush their teeth and go to the bathroom as well when they wake up. However, because of micro-gravity (微重力), astronauts take care of themselves in different ways. For example, they use a kind of special tool to wash their hair and use leg restraints (腿部固定装置) to set themselves when they use the washing room. 

③Astronauts eat three meals a day: breakfast, lunch and dinner. Some food can be eaten in the natural form, such as fruit. There are no fridges in space, so space food must be kept in a good way to avoid going bad. 

④Besides morning routine (常规) and eating in space, astronauts also need to do many tasks, such as checking the machines, updating (更新) computer information and so on. At the same time, the control center on Earth sends messages to the astronauts through voice or email to help them in their daily routines. 

⑤What's more, living in space is not just all work and no play. A popular way of relaxation is looking out of the window. And they can also enjoy themselves by watching movies, reading books, playing cards and talking to their families during their free time. 

"I am Peppa Pig. This is my little brother George! This is Mommy Pig and this is Daddy Pig! " Do you know this family? I like them very much. Peppa Pig is from England, and she is four years old. Her favorite thing is to play with her best(最好的) friend Suzy and her brother George. Who's George's best friend? Peppa? No! His best friend is his dinosaur(恐龙). He takes(带着) his dinosaur everywhere. Mommy Pig is beautiful. She cooks for the family. Daddy Pig sometimes cooks for them, too. They often jump in muddy puddles(泥坑) with Peppa and George. They are very happy.
