Lesson 48 Did you want to tell me something? 你想对我说什么吗? Why did the writer become very worried? Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. I tried to say something, but my mouth was full of cotton wool. He knew I collected match boxes and asked me whether my collection was growing. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. When the dentist at last removed the cotton wool from my mouth, I was able to tell him that he had pulled out the wrong tooth. 参考译文 牙科医生们总是在你无法作出回答的时候向你提出问题。我的牙科医生刚刚给我拔掉了一颗牙,叫我休息一会儿。我想说点什么,但我嘴里塞满了药棉。他知道我收集火柴盒,于是问我收藏的米柴盒是否在增加。接着他又问我的兄弟近来如何,问我是否喜欢伦敦的新工作。作为对这些问题的回答,我不是点头,就是发出奇怪的声音。与此同时,我的舌头正在忙着寻找刚拔掉的那颗牙的伤口。我突然非常着急起来,但却什么也说不出来。当那位牙医最后将药棉从我嘴中取出时,我总算有可能告诉他,他拔错了牙。 一、New words and expressions 生词和短语 pull 1) v. 拔(草,瓶塞,钉子等),拔掉,拉开 例: I spent a whole day pulling weeds. 我花一整天时间来拔草。 pull out a nail 拔出钉子 pull out a stopper 拔出塞子 have the decayed tooth pulled out请(牙医)拔掉蛀牙 pull out the wrong tooth 拔错了牙 eg.

When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously. However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar. The hunt for the puma began in a small village where a woman picking blackberries saw 'a large cat' only five yards away from her. It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered(adj.被困得走投无路的). The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening. Wherever it went, it left behind it a trail of dead deer and small animals like rabbits. Paw prints were seen in a number of places and puma fur was found clinging to bushes. Several people

新概念第三册课文翻译及学习笔记:Lesson58 【课文】 The old lady was glad to be back at the block of flats where she lived. Her shopping had tired her and her basket had grown heavier with every step of the way home. In the lift her thoughts were on lunch and a good rest; but when she got out at her own floor, both were forgotten in her sudden discovery that her front door was open. She was thinking that she must reprimand her home help the next morning for such a monstrous piece of negligence, when she remembered that she had gone shopping after the home help had left and she knew that she had turned both keys in their locks, She walked slowly into the hall and at once noticed that all the room doors were open, yet following her regular practice she had shut them before going out. Looking into the drawing room, she saw a scene of confusion over by her writing desk. It was as clear as daylight then that burglars had forced an entry during her absence. Her first impulse was to go round all the rooms looking for the thieves, but then she decided that at her age it might be more prudent to have someone with her, so she went to fetch the porter from his basement. By this time her legs were beginning to tremble, so she sat down and accepted a cup of very strong tea, while he telephoned the police. Then, her composure regained, she was ready to set off with the porter's assistance to search for any intruders who might still be lurking in her flat. They went through the rooms, being careful to touch nothing, as they did not want to hinder the police in their search for fingerprints. The chaos was inconceivable. She had

新概念第三册课文翻译及学习笔记:Lesson3 【课文】 Listen to the tape then answer the question below. 听录音,然后回答以下问题。 How did the archaeologists know that the statue was a goddess? Some time ago, an interesting discovery was made by archaeologists on the Aegean island of Kea. An American team explored a temple which stands in an ancient city on the promontory of Ayia Irini. The city at one time must have been prosperous, for it enjoyed a high level of civilization. Houses -- often three storeys high -- were built of stone. They had large rooms with beautifully decorated walls. The city was even equipped with a drainage system, for a great many clay pipes were found beneath the narrow streets. The temple which the archaeologists explored was used as a place of worship from the fifteenth century B.C. until Roman times. In the most sacred room of temple, clay fragments of fifteen statues were found. Each of these represented a goddess and had, at one time, been painted. The body of one statue was found among remains dating from the fifteenth century B.C. Its missing head happened to be among remains of the fifth century B.C. This head must have been found in Classical times and carefully preserved. It was very old and precious even then. When the archaeologists reconstructed the fragments, they were amazed to find that the goddess turned out to be a very modern-looking woman. She stood three feet high and her hands rested on her hips. She was wearing a full-length skirt which swept

Smash-and-grab 砸橱窗抢劫 The expensive shops in a famous arcade near Piccadilly were just opening. At this time of the morning, the arcade was almost empty. Mr Taylor, the owner of a jewellery shop was admiring a new window display. Two of his assistants had been working busily since 8 o'clock and had only just finished. Diamond necklaces and rings had been beautifully arranged on a background of black velvet. After gazing at the display for several minutes, Mr Taylor went back into his shop. The silence was suddenly broken when a large car, with its headlights on and its horn blaring, roared down the arcade. It came to a stop outside the jeweler's. One man stayed at the wheel while two others with black stockings over their faces jumped out and smashed the window of the shop with iron bars. While this was going on, Mr Taylor was upstairs. He and his staff began throwing furniture out of the window. Chairs and tables went flying into the arcade. One of the thieves was struck by a heavy statue, but he was too busy helping himself to diamonds to notice any pain. The raid was all over in three minutes, for the men scrambled back into the car and it moved off at a fantastic speed. Just as it was leaving, Mr Taylor rushed out and ran after it throwing ashtrays and vases, but it was impossible to stop the thieves. They had got away with thousands of pounds worth of diamonds.

Wherever it went, it left behind it a trail of dead deer and small animals like rabbits. Paw prints were seen in a number of places and puma fur was found clinging to bushes. Several people complained of 'cat-like noises' at night and a businessman on a fishing trip saw the puma up a tree. The experts were now fully convinced that the animal was a puma, but where had it come from ? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape. The hunt went on for several weeks, but the puma was not caught. It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside. 美洲狮是一种体形似猫的大动物,产于美洲。当伦敦动物园接到报告说,在伦敦以南45英里处发现一只美洲狮时,这些报告并没有受到重视。可是,随着证据越来越多,动物园的专家们感到有必要进行一番调查,因为凡是声称见到过美洲狮的人们所描述的情况竟是出奇地相似。 搜寻美洲狮的工作是从一座小村庄开始的。那里的一位妇女在采摘黑莓时的看见“一只大猫”,离她仅5码远,她刚看见它,它就立刻逃走了。专家证实,美洲狮非被逼得走投无路,是决不会伤人的。事实上搜寻工作很困难,因为常常是早晨在甲地发现那只美洲狮,晚上却在20英里外的乙地发现它的踪迹。无论它走哪儿,一路上总会留下一串死鹿及死兔子之类的小动物,在许多地方看见爪印,灌木丛中发现了粘在上面的美洲狮毛。有人抱怨说夜里听见“像猫一样的叫声”;一位商人去钓鱼,看见那只美洲狮在树上。专家们如今已经完全肯定那只动物就是美洲狮,但它是从哪儿来的呢?由于全国动物园没有一家报告丢了美洲狮,因此那只美洲狮一定是某位私人收藏豢养的,不知怎么设法逃出来了。搜寻工作进行了好几个星期,但始终未能逮住那只美洲狮。想到在宁静的乡村里有一头危险的野兽继续逍遥流窜,真令人担心。 Lesson 2 Thirteen equals one Our vicar is always raising money for one cause or another, but he has never managed to get enough money to have the church clock repaired. The big clock which used to strike the hours day and night was damaged many years ago and has been silent ever since. ' One night, however, our vicar woke up with a start: the clock was striking the hours! Looking at his watch, he saw that it was one o'clock, but the bell struck thirteen times before it stopped. Armed with a torch, the vicar went up into the clock tower to see what was going on. In the torchlight, he caught sight of a figure whom he immediately recognized as Bill Wilkins, our local grocer. 'Whatever are you doing up here Bill ?' asked the vicar in surprise. ' I'm trying to repair the bell,' answered Bill.' I've been coming up here night after night for weeks now. You see, I was hoping to give you a surprise.' 'You certainly did give me a surprise!' said the vicar. 'You've probably woken up everyone in the village as well. Still, I'm glad the bell is working again.' 'That's the trouble, vicar,' answered Bill. 'It's working all right, but I'm afraid that at one o'clock it will strike thirteen times and there's nothing I can do about it.' 'We'll get used to that Bill,' said the vicar. 'Thirteen is not as good as one but it's better than nothing. Now let's go downstairs and have a cup of tea.' 我们教区的牧师总是为各种各样的事筹集资金。但始终未能筹足资金把教堂的钟修好。教堂的钟很大,以前不分昼夜打点报时,但很多年前遭到毁坏,从此便无声无息了。 一天夜里,我们的牧师突然被惊醒了,大钟又在“打点”报时了!他一看表,才1点钟,可是那钟一边敲了13下才停。牧师拿着一
