Lesson 1 A private conversation 私人谈话 Last week I went to the theatre. I had a very good seat.  The play was very interesting. I did not enjoy it.  A young man and a young woman were sitting behind me. They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily.  ' It's none of your business,' the young man said rudely. 'This is a private conversation!'.Lesson 2 Breakfast or lunch? 早餐还是午餐？ It was Sunday. I never get up early on Sundays. I sometimes stay in bed until lunch time.Last Sunday I got up very late. I looked out of the window. It was dark outside. 'What a day!' I thought. 'It's raining again.' Just then, the telephone rang. It was my aunt Lucy.' I've just arrived by train,' she said. 'I'm coming to see you.' 'But I'm still having breakfast,' I said.'What are you doing ?' she asked. ' I'm having breakfast,' I repeated.'Dear me,' she said. 'Do you always get up so late ? It's one o'clock!''Lesson 3 Please send me a card 请给我寄一张明信片 Postcards always spoil my holidays. Last summer, I went to Italy. I visited museums and sat in public gardens. A friendly waiter taught me a few words of  Italian. 'Then he lent me a book. I read a few lines, but I did not understand a word. Every day I thought about postcards. My holidays passed quickly, but I did not send any cards to my friends. On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card !Lesson 4 An exciting trip 激动人心的旅行I have just received a letter from my brother, Tim. He is in Australia. He has been there for six months. Tim is an engineer. He is working for a big firm and he has already visited a great number of different places in Australia. He has just bought an Australian car and has gone to Alice Springs, a small town in the centre of Australia. He will soon visit Darwin. From there, he will fly to Perth.  My brother has never been abroad before, so he is finding this trip very exciting.Lesson 5 No wrong numbers 无错号之虞 Mr James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private telephone service.Lesson 6 Percy Buttons 珀西·巴顿斯I have just moved to a house in Bridge Street. Yesterday a beggar knocked at my door. He asked me for a meal and a glass of beer. In return for this, the beggar stood on his head and sang songs. I gave him a meal. He ate the food and drank the beer. Then he put a piece of cheese in his pocket and went away. Later a neighbour told me about him. Everybody knows him. His name is Percy Buttons. He calls at every house in the street once a month and always asks for a meal and a glass of beer.   Lesson 7 Too late 为时太晚  The plane was late and detectives were waiting at the airport all morning. They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds. When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. Two men took the parcel off the plane and carried it into the Customs House. While two detectives were keeping guard at the door, two others opened  the parcel. To their surprise, the precious parcel was full of stones and sand!   Lesson 8 The best and the worst 最好的和最差的 Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the garden competition too, and I always win a little prize for the worst garden in the town!   Lesson 9 A cold welcome 冷遇 On Wednesday evening, we went to the Town Hall. It was the last day of the year and a large crowd of people had gathered under the Town Hall clock. It would strike twelve in twenty minutes' time. Fifteen minutes passed and then, at five to twelve, the clock stopped. The big minute hand did not move. We waited and waited, but nothing happened. Suddenly someone shouted, 'It's two minutes past twelve! The clock has stopped!' I looked at my watch. It was true. The big clock refused to welcome the New Year. At that moment everybody began to laugh and sing.   Lesson 10 Not for jazz 不适于演奏爵士乐 We have an old musical instrument. It is called a clavichord(翼琴). It was made in Germany in 1681. Our clavichord is kept in the living-room. It has belong to our family for a long time. The instrument was bought by my grandfather many years ago. Recently it was damaged by a visitor. She tried to play jazz on it! She struck the keys too hard and two of the strings were broken. My father was shocked. Now we are not allowed to touch it. It is being repaired by a friend of my father's.   Lesson 11 One good turn deserves another 礼尚往来 I was having dinner at a restaurant when Harry Steele came in. Harry worked in a lawyer's office years ago, but he is now working at a bank. He gets a good salary, but he always borrows money from his friends and never pays it back. Harry saw me and came and sat at the same table. He has never borrowed money from me. While he was eating, I asked him to lend me &2. To my surprise, he gave me the money immediately. 'I have never borrowed any money from you,' Harry said, 'so now you can pay for my dinner!'   Lesson 12 Goodbye and good luck 再见，一路顺风 Our ncighbour, Captain Charles Alison, will sail from Portsmouth tomorrow. We shall meet him at the harbour early in the morning. He will be in his small boat, Topsail.Tapsail is a famous little boat. It has sailed across the Atlantic many times. Captain Alison will set out at eight o'clock so we shall have plenty of time. We shall see his boat and then we shall say good-bye to him. He will be away for two months. We are very proud of him. He will take part in an important race across the Atlantic.   Lesson 13 The Greenwood Boys 绿林少年 The Greenwood Boys are a group of popular singers. At present, they are visiting all parts of the country. They will be arriving here tomorrow. They will be coming by train and most of the young people in the town will be meeting them at the station. Tomorrow evening they will be singing at the Workers' Club. The Greenwood Boys will be staying for five days. During this time, they will give five performances. As usual, the police will have a difficult time. They will be trying to keep order. It is always the same on these occasions.   Lesson 14 Do you speak English? 你会讲英语吗？ I had an amusing experience last year.  After I had left a small village in the south of France, I drove on to the next town. On the way, a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all. Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said, very slowly, 'Do you speak English?' As I soon learnt, he was English himself!   Lesson 15 Good news 佳音  The secretary told me that Mr. Harmsworth would see me. I felt very nervous when. I went into his office. He did not look up from his desk when I entered. After I had sat down, he said that business was very bad. He told me that the firm could not afford to pay such large salaries. Twenty people had already left. I knew that my turn had come. 'Mr. Harmsworth,' I said in a weak voice. 'Don't interrupt,' he Said. Then he smiled and told me I would receive an extra &100 a year!   Lesson 16 A polite request 彬彬有礼的要求 If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:' Sir, we welcome you to our city. This is a "No Parking" area. You will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it!   Lesson 17 Always young 青年常驻 My aunt Jennifer is an actress. She must be at least thirty-five years old. In spite of this, she often appears on the stage as a young girl. Jennifer will have to take part in a new play soon. This time, she will be a girl of seventeen. In the play, she must appear in a bright red dress and long black stockings. Last year in another play, she had to wear short socks and a bright, orange-coloured dress. If anyone ever asked her how old she is, she always answers, 'My dear, it must be terrible to be grown up!'   lesson18 He often does this! 他经常干这种事！ After I had had lunch at a village inn, I looked for my bag. I had left it on a chair beside the door and now it wasn't there ! As I was looking for it, the inn-keeper came in. 'Did you have a good meal ?' he asked. 'Yes, thank you,' I answered, 'but I can't pay the bill. I haven't got my bag.' The inn-keeper smiled and immediately went out. In a few minutes he returned with my bag and gave it back to me. 'I'm very sorry,' he said ' My dog had taken it into the garden. He often does this.'   Lesson19 Sold out 票已售完 'The play may begin at any moment,' I said.   'It may have begun already,' Susan answered. 'I hurried to the ticket-office. 'May I have two tickets please ?' I asked. 'I'm sorry, we've sold out,' the girl said. 'What a pity!' Susan exclaimed. Just then, a man hurried to the ticket-office. 'Can I return these two tickets?' he asked. 'Certainly,' the girl said. 'Could I have those two tickets please ?' I asked. 'Certainly, 'the girl said, 'but they are for next Wednesday's performance. 'I might as well have them,' I said sadly.   Lesson20 One man in a boat 独坐孤舟 Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all !   Lesson21 Mad or not? 是不是疯了？ Aeroplanes are slowly driving me mad. I live near an airport and passing planes can be heard night and day. The airport was built during the war, but for some reason it could not be used then. Last year, however, it came into use. Over a hundred people must have been driven away from their homes by the noise. I am one of the few people left. Sometimes I think this house will be knocked down by a passing plane. I have been offered a large sum of money to go away, but I am determined to stay here. Everybody says I must be mad and they are probably right   Lesson22 A glass envelope 玻璃信封 My daughter, Jane, never dreamed of receiving a letter from a girl of her own age in Holland. Last year, we were travelling across the Channel and Jane put a piece of paper with her name and address on it into a bottle. She threw the bottle into the sea. She never thought of it again, but ten months later, she received a letter from a girl in Holland. Both girls write to each other regularly now. However, they have decided to use the post-office. Letters will cost a litt1e more, but they will certainly travel faster.    Lesson23 A new house 新居 I had a letter from my sister yesterday. She lives in Nigeria. In her letter, she said that she would come to England next year. If she comes, she will get a surprise. We are now  living in a beautiful new house in the country. Work on it had begun before my sister left. The house was completed
