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.

    They were a happy family: four daughters all in the same school in different grades. The youngest, Janice, who was in my class, seemed to be glued （粘）to her mother's skirts. The three older girls took the bus to school every morning, but Janice was always driven to school by her mother.

    One Friday, Janice's mother asked for a talk with me. She said in a soft voice, "My husband is going to Europe on business for two weeks, and he insists that I go with him. I have tried to explain over and over that Janice needs me here. But he thinks that she will be fine without me so I have no choice; I have to go. I have told the babysitter to drive her every morning. Will you please give Janice special attention and help her? I want to be sure everything goes well for her." I told her that we would make every effort to support Janice. I even volunteered to meet Janice at her car so she would see a familiar face. As a mother myself, I'd like to help. Janice's mother thanked me for our understanding.

    On Monday morning, expecting a tearful, anxious child, I planned a special program of fun and games. I waited outside to greet Janice, but just then the bus arrived and not three, but four girls got off. Janice skipped along joyfully, saying "goodbye" to her sisters as she ran with two friends into the classroom. I walked slowly into the classroom and called Janice over to ask how the bus ride went. Impatiently she said, "Oh, I always want to take the bus with the other kids, but Mother needs to be with me. You see there won't be any more babies, so I have to be a baby a little longer. While she is away, I'll just ride the bus every day. I am five, you know.

    Temples have existed for thousands of years. They are the proof of cultures and civilization that existed many years ago.

    Gobekli Tepe, Turkey

    Located on a hilltop in southwestern Turkey where it snows a lot in winter, the Gobekli Tepe is considered the world's oldest temple. It is nearly 11,000 years old. There are carvings on the rock statues, mainly of lions, foxes, snakes, cranes and wild ducks, as well as scenes of people hunting. Because heavy snow makes it hard to get to the top of the hill, visitors are not recommended to go there in winters.

    White Temple, Thailand

    Immediately upon entering White Temple, you will realize this contemporary, unconventional temple stands out, even in a country dotted with temples. The White Temple is incredibly different and unique in its architecture, art and design. In fact, it is designed in a very modern way. This temple is all white. It is very hot in summer in Thailand, so going to White Temple in other three seasons is a wise choice.

    Sagrada Familia, Spain

    This symbolic Barcelona building is famously unfinished. It is said to be finished by 2026, but no body believes it. However, visitors believe its incompleteness is part of its charm, which sets it apart from other temples in the world. You will have to wait in a long line if you visit Sagrada Familia in summer holiday. Visitors are not that many in spring and winter.

    Kinkaku-ji, Japan

    This temple is absolutely the most popular one in Japan. Whether you visit during the fall when there are red leaves against the golden wall, in winter when the gold is topped with pure white snow, in spring with cherry blossoms, or in summer allowing you to smell the earthy smell after rain – there is never a bad time to visit this beautiful temple.

    My sister Alice and I have been trying to get people to stop dropping cigarette (香烟)butts(烟头)for seven years. One day, we were walking in our hometown and saw hundreds of cigarette butts on the ground. They made the town look so ugly that we decided to start a group to make people dropping butts. We called it "No Butts About It".

    At first, we drew pictures with "The Earth is not your ashtray(烟灰缸)"written on them. We put the pictures around our hometown—in parks, by beaches, and along roads. We wanted to make people understand that dropping butts hurts the environment. Most smokers don't think that dropping butts hurts the Earth. But it does, and all rubbish does!

    Later, we wrote to companies and asked them for money to help us. We used the money to buy ashtrays to give to smokers. We wanted smokers to carry the ashtrays with them so they didn't have to drop butts.

    At the moment, we are trying to get cigarette companies to put an ashtray in each pack of cigarettes. Some companies want to do it. Many people have started to join our group since it began. Today there are 45 other "No Butts About It" groups in America.

    Now there even groups in England, Australia, and India! Many newspapers have written about my sister and me over the last seven years. And we have won many prizes for what we do. But we are not interested in prizes. We just want to make the Earth a better and cleaner place for animals, plants and people.

    One day, it will be.

We have met, but just not in person.I work in the bank and I usually do my work over the phone and computer.This lady is a borrower of my bank，one of the people I serve.We have had several conversations about her borrowings.She is neither a woman that is of my mother's age, nor a grand－motherly type of client (客户), because men or women of that age are always very loving and they remind me what I should do.This woman is of my age.

We have never met in person.She lives in New Jersey and I live in California.Her borrowings turned out great, and I didn't worry even a little bit.To be honest, I think I just worked normally to finish my service.But every couple of months, she would email me a little note, telling me how I made a difference to her life, and how thankful she was for what I had done.I never expected that.

I have a busy and stressful job.Every day, I meet many people and I offer the same service to them.I also keep a working relationship with many.No one has done that for me.I don't think I have done something different or helped her much.She just used her time and the most shining part in her heart to send me emails.I saw the beauty inside her.

Everyone can be tired and lonely right now.The same is true of the woman.Take a moment in your day to do one little nice thing for somebody，even if it's for someone you do not know.You can make a little difference to their life and also to yours.It feels good to say I feel a little love today and that I find myself showing it to somebody else.
