【正文】 garettes and cigars. They made no effort to hide their amusement whenever I produced a packet of sweets from my pocket. After seven days of this I went to a party. Everybody around me was smoking and I felt extremely unfortable. When my old friend Brian urged me to accept a cigarette, it was more than I could bear. I took one guiltily, lit it and smoked with satisfaction. My wife was delighted that things had returned to normal once more. Anyway, as Brian pointed out, it is the easiest thing in the world to give up smoking. He himself has done it lots of times! I used to travel by air a great deal when I was a boy. My parents, used to live in South America and I used to fly there from Europe in the holidays. An airhostess would take charge of me and I never had an unpleasant experience. I am used to travelling by air and only on one occasion have I ever felt frightened. After taking off, we were flying low over the city and slowly gaining height, when the plane suddenly turned round and flew back to the airport. While we were waiting to land, an airhostess told us to keep calm and to get off the plane quietly as soon as it had touched down. Everybody on board was worried and we were curious to find out what had happened. Later we learnt that there was a very important person on board. The police had been told that a bomb had been planted on the plane. After we had landed, the plane was searched thoroughly. Fortunately, nothing was found and five hours later we were able to take off again. The Crystal Palace 水晶宮s steam hammer. Though in those days, travelling was not as easy as it is today, steam boats carried thousands of visitors across the Channel from Europe. On arriving in England, they were taken to the Crystal Palace by train. There were six million visitors in all, and the profits from the exhibition were used to build museums and colleges. Later, the Crystal Palace was moved to South London. It remained one of the most famous buildings in the world until it was burnt down in 1936.When he had killed the guard, the prisoner of war quickly dragged him into the bushes. Working rapidly in the darkness, he soon changed into the dead man39。Lesson82 Monster or fish? 是妖還是魚?monsters39。 are washed to the shore, but they are rarely caught out at sea. Some time ago, however, a peculiar fish was caught near Madagascar. A small fishingboat was carried miles out to sea by the powerful fish as it pulled on the line. Realizing that this was no ordinary fish, the fisherman made every effort not to damage it in any way. When it was eventually brought to shore, it was found to be over thirteen feet long. It had a head like a horse, big blue eyes, shining silver skin, and a bright red tail, The fish, which has since been sent to a museum where it is being examined by a scientist, is called an oarfish. Such creatures have rarely been seen alive by man as they live at a depth of six hundred feet.The former Prime Minister, Mr Wentworth Lane, was defeated in the recent elections. He is now retiring from political life and has gone abroad. My friend, Crawley, has always been a fanatical opponent of Mr Lane39。s house. When he asked if Mr Lane lived there, the policeman on duty told him that since his defeat, the exPrime Minister had gone abroad. On the following day, Crawley went to the house again. The same policeman was just walking slowly past the entrance, when Crawley asked the same question. Though a little suspicious this time, the policeman gave him the same answer. The day after, Crawley went to the house once more and asked exactly the same question. This time, the policeman lost his temper.39。 he shouted, 39。 39。 answered Crawley,39。 Busmen have decided to go on strike next week. The strike is due to begin on Tuesday. No one knows how long it will last. The busmen have stated that the strike will continue until general agreement is reached about pay and working conditions. Most people believe that the strike will last for at least a week. Many owners of private cars are going to offer 39。 to people on their way to work. This will relieve pressure on the trains to some extent. Meanwhile, a number of university students have volunteered to drive buses while the strike lasts. All the young men are expert drivers, but before they drive any of the buses, they will have to pass a special test. The students are going to take the test in two days39。Lesson85 Never too old to learn 活到老學(xué)到老s home. We shall all remember Mr Page for his patience and understanding and for the kindly encouragement he gave us when we went so unwillingly to school. A great many former pupils will be attending a farewell dinner in his honour next Thursday. It is a curious coincidence that the day before his retirement, Mr Page will have been teaching for a total of forty years. After he has retired, he will devote himself to gardening. For him, this will be an entirely new hobby. But this does not matter, for, as he has often remarked, one is never too old to learn. As the man tried to swing the speedboat round, the steeringwheel came away in his hands. He waved desperately to his panion, who had been waterskiing for the last fifteen minutes. Both men had hardly had time to realize what was happening when they were thrown violent1y into the sea. The speedboat had struck a buoy, but it continued to move very quickly across the water. Both men had just begun to swim towards the shore. when they noticed with dismay that the2可行性分析2010年4月25日目錄一、概況二、建設(shè)規(guī)模及廠址的選擇三、產(chǎn)品方案四、原料來源五、工藝流程六、三廢治理和環(huán)境保護七、投資估算八、銷售收入、生產(chǎn)成本及損益測算一、 概況全球陸基鎳儲量約為12000萬噸,其中40%為硫化礦,60%為氧化礦(紅土礦),硫化礦主要分布在俄羅斯、加拿大和中國,總量約5000萬噸,目前鎳產(chǎn)量的60%來自硫化礦。紅土礦資源的特點:1)資源豐富,埋藏淺,易勘探,均為露天開采,采礦成本低。 3)紅土礦產(chǎn)于熱帶、亞熱帶、大多瀕臨海洋,交通運輸方便。目前國外的許多知名鎳生產(chǎn)企業(yè)都已涉足紅土礦開發(fā),部分已取得了實質(zhì)性進展。由于硫化鎳可供開發(fā)資源的明顯減少,世界未來十年鎳產(chǎn)量的增加將主要來源于紅土型鎳礦資源的開發(fā),而紅土型鎳礦資源開發(fā)中,濕
