One day while driving from my home to work. I noticed a car in front of me had a wobbly(不稳定的) wheel. It was clear that the wheel had been changed recently and had not been fixed correctly. On a slow road this would not show much of a problem but I knew a highway was coming soon. There the traffic would move much faster and the driver would be in danger as the wheel could come off at that speed.

    I was driving a large jeep at the time and the car in front was a small one driven by a young lady on her own. So as I tried to flash(闪) my lights and wave her to pullover,  I was worried that she wouldn't pull over on the road side when she found in her mirror a single man chasing(追) her down in a jeep and waving for her to pull over.

    Thankfully. she trusted more in the good nature of people and pulled over where I could explain the problem. She said the wheel was changed only the night before and that she would pull into the nearest garage(修车间) where the repairman had tools to fix the wheel correctly.

    My belief is that the act of kindness was hers and not mine. How so? Well, it was she who chose to believe in the possibility that people are good over the belief that bad things would come from being waved over to the side of the road by strangers.

    I am glad I was able to wave her down in time and so a serious accident might have been avoided. But I am even happier that she believed in a stranger.

    My mother is a teacher. On weekdays, she gives lessons at school and on Saturdays she works in clubs. On Sundays, she is still busy.

On Sunday morning, mum gets up at six. She cooks breakfast for us first. And then it's time for cleaning. After that, she has breakfast with father and me. At 9, she goes to buy food for lunch in the supermarket. She can have a short rest after lunch. In the afternoon, mum doesn't go out. She helps me with my lessons. She does some reading, too.

    Mother watches TV at about 7 when she finishes (完成) the housework. But at that time she is always tired and falls asleep (睡着) in the sofa sometimes.

    Mark Twain left school when he was twelve. He had little school education. In spite of this, he became the most famous writer of his time. He made millions of dollars by writing. His real name was Samuel Langhorne Clemens, but he is better known all over the world as Mark Twain, his penname.

    Mark Twain was born in 1835 and he was not a healthy baby. In fact, he was not expected to live through the first winter. But with his mother's care, he managed to survive. As a boy, he caused much trouble for his parents. He used to play jokes on all his friends and neighbors. He didn't like to go to school, and he often ran away from home. He always went in the direction of the nearby Mississippi. He was nearly drowned nine times.

    After his father's death, Mark Twain began to work for a printer, who only provided him with food and clothing. Then, he worked as a printer, a river-boat pilot and later joined the army. But shortly after that he became a miner. During this period, he started to write short stories. Afterwards he became a full time writer.

    In 1870, Mark Twain got married. In the years that followed he wrote many books including Tom Sawyer in 1876, and Huckleberry Finn in 1884, which made him famous, and brought him great fortune.

    Unfortunately, Mark Twain got into debts in bad investments(投资) and he had to write large numbers of stories to pay these debts. In 1904, his wife died, and then three of his children passed away.

    At the age of 70, his hair was completely white. He bought many white suits and neckties. He wore nothing but white from head to foot until his death on April 21, 1910.

    Treasure hunts have excited people's imagination for hundreds of years both in real life and in books such as Robert Louis Stevenson's Treasure Island. Kit Williams, a modern writer, had the idea of combining the real excitement of a treasure hunt with clues found in a book when he wrote a children's story, Masquerade, in 1979. The book was about a hare, and a month before it came out Williams buried(埋) a gold hare in a park in Bedfordshire. The book contained a large number of clues to help readers find the hare, but Williams put in a lot of "red herrings", or false clues, to mislead them.

    Ken Roberts, the man who found the hare, had been looking for it for nearly two years. Although he had been searching in the wrong area most of the time, he found it by logic(逻辑), not by luck. His success came from the fact that he had gained an important clue at the start. He had realized that the words: "One of Six to Eight" under the first picture in the book connected the hare in some way to Katherine of Aragon, the first of Henry VⅢ's six wives. Even here, however, Williams had succeeded in miss leading him. Ken knew that Katherine of Aragon had died at Kimbolton in Cambridgeshire in 1536 and thought that Williams had buried the hare there. He had been digging there for over a year before a new idea came to him. He found out that Kit Williams had spent his childhood near Ampthill, in Bedfordshire, and thought that he must have buried the hare in a place he knew well, but he still could not see the connection with Katherine of Aragon, until one day he saw two stone crosses in Ampthill Park and learnt that they had been build in her honor in 1773.

    Even then his search had not come to an end. It was only after he had spent several nights digging around the cross that be decided to write to Kit Williams to find out if he was wasting his time there. Williams encouraged him to continue, and on February 24th 1982, he found the treasure. It was worth £3000 in the beginning, but the excitement it had caused since its burial made it much more valuable.

    It is a fine Sunday morning. Ann and her mother are on a big bus. There are many people on it. Some of them come from America, and some come from England and Canada. They are going to the Great Wall.

    There are only two Chinese on the bus. One is the woman. She is driving the bus. The other is a young man. He is their guide and can speak English very well. Now he is talking with an American girl. Other people are listening to them. They are very interested in the Great Wall. They want to see it very much.
