When the Normans built their first simple wooden castles in England，they built them on the top of small hills.The first permanent castles were made of stone and built with thick walls.The main building was usually surrounded by walls which overlooked the moat (护城河)．

     The entrance to the castle was usually over a drawbridge (吊桥) leading to the main gatehouse.The drawbridge could be raised or lowered and an iron grille (栅栏) could be lowered to shut off the entrance to the gatehouse.

     As time went on，the castle builders became more advanced in their techniques.Instead of building a strong central building and surrounding it with walls of lesser strength，they thought out the idea of surrounding a central area with huge walls which could contain all the main rooms of the castle.These walls usually had many towers and these towers were really a series of main buildings along the castle walls.In building these castles they used hill sites whenever possible in order to give the castle a better position.Because the outside world was shut off by a barrier or curtain of defences，they are called “curtain wall” castles.

     With the passing of time there was less need to build strong castles and nobles built manor (庄园) houses.These manor houses often had battlements and iron grilles，but they were built more for comfort and included many of the conveniences and luxuries of the large houses which were being built in the towns.

     Unfortunately，many English castles were damaged or destroyed completely during the Civil Wars of the 1600s.

    One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

    Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.

    Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.

    Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!

    ______ — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!

    A few days ago my wife sent me out to buy something. When I came home, I handed her a paper bag and said, "Here are the apples you wanted." She looked in the bag, and then she looked at me. "I told you," she said slowly, "to buy some eggs."

    I felt worried about my absent-mindedness (心不在焉，健忘) , so I went to see a doctor. He was a very kind man. "I have seen many people like you. It's nothing to worry about," he said. "If you know you are absent-minded, you are all right. But if you do not know you're absent-minded, you may be really in trouble."

    "Many famous people were absent-minded," the doctor told me. "Thomas Edison was standing in line one day to pay his taxes. When he arrived at the window, he found that he had forgotten his own name. He had to ask the man who was behind him to tell him who he was."

    I felt much better and got up to leave. "Thank you, doctor," I said. "How much do I have to pay you?"

    "Ten dollars for the check-up," the doctor said.

    "But doctor, I did not have a check-up!"

    For a moment the doctor looked puzzled. Then he said, "Oh, yes, it was the patient before you who had a check-up. How absent-minded I am!"

    As I was thinking about language learning the other day, the image of baking bread came into my mind. I compared some of the exercises and drills that we put ourselves through in order to learn a language to the various ingredients that go into baking a loaf of fresh bread.

    Real language learning takes place in human relationships. No one sits down and eats a cup of flour, even if he is hungry and in a hurry. You don't become bilingual（双语的）by learning lists of vocabulary. You don't become a speaker of a language by memorizing verb conjugations（动词的词形变化）and agreement rules. You become bilingual by entering a community that uses that other language as its primary means of communication.

    I am not suggesting that we can make bread without ingredients. Flour is necessary, as are yeast, salt, water and other ingredients. Vocabulary is part of any language and will have to be learned. Grammatical rules exist in every language and cannot be ignored. But merely combining the appropriate ingredients in the recommended proportions does not result in bread. At best, you only end up with a ball of dough（面团）.

    In order to get bread, you have to apply heat to the dough. And in language learning, that heat comes from the community. Anyone who has learned a second language has experienced that heat. It creeps up your neck when you ask the babysitter, “Have you already been eaten?” when you meant to say, “Have you already eaten?” When you try to say something quite innocent and the whole room bursts into laughter, you are experiencing the heat that turns raw dough into good bread.

    Remember the old saying, “If you can't stand the heat, get out of the kitchen”? This is where language learning often breaks down because we find the heat uncomfortable and we stop the baking process. In other words, we can't stand the heat, so we get out of the kitchen.

    However, the language learner who stays in the kitchen—in the heat—until the combined ingredients are thoroughly transformed will enjoy the richness of a quality loaf of bread. He said that he did not “get out of the kitchen” at the critical moment when the oven seemed too hot. The dedicated language learner knows that becoming bilingual cannot be achieved without the heat!

    Japanese technology giant Toshiba has built a huge "clean" factory farm where it is growing various types of lettuce (莴苣) leaves without sunlight or soil for sale in its new healthcare business.

    Located in a disused 21,000­square­foot electronics factory in Yokosuka, Toshiba announces to have created a perfect "bacteria­free" environment where it will grow three million bags of lettuce a year.

    Completely cut off from conditions outside the temperature controlled tank, lettuce inspectors wear full body suits while making notes on the quality and growth of the leaves on their iPads in order to prevent the air around the plants becoming contaminated.

    Each plant is given man­made lighting to trick it into believing it is exposed to sunlight, while vitamin and nutrients are put directly into its roots, meaning the lettuce does not need soil.

    Toshiba's new high­tech farm may produce the world's highest quality lettuce. The final product will be free of any form of bacteria or insect life before being placed into sealed (密封的) bags, which should ensure the product has a longer shelf life than other lettuces.

    The gardening technique aims to have a bacteria amount of no more than 1/1000th­much lower than that found in normal gardening soil.

    Toshiba aims to harvest three million bags of leaf lettuce, baby leaf greens, cabbages and other kinds of vegetables every year­with each bag likely to cost people £1.

    The most important thing in organic vegetables, the lettuce requires no pesticides (杀虫剂) but is expected to have a similar shelf to plants that have been heavily treated with chemicals.

    The lettuce factory is no marketing trick by Toshiba, however. Instead it represents the company's latest attempt to expand its technology­led business.

    There are already plans for the technology giant to build similar factories around the world over the coming years and it will also be selling the high tech equipment that allows factories to produce similar products of exceptionally high quality.

    Children aged 5 and under can have their faces painted for FREE by Mr. Garcia's third-grade art class.

    No fair would be complete without food. We will be selling hot dogs, ice cream, roasted nuts, and cotton candy at our booths. For those of you who love to bake, why not enter our new apple pie contest? Just bring your pie to the pie table on the morning of the fair. At 1 p. m., our judges, Coach Carter and math teacher, Mrs. Adams, will choose a winner.
