英语100篇精读荟萃? 文件名称: 英语100篇精读荟萃 文件大小:313KB 附件阅读权限 :20 分包下载:共1包 文件格式:doc 共3篇WORD文档 Passage one ( The only way to travel is on foot ) The past ages of man have all been carefully labeled by anthropologists. Descriptions like ‘ Palaeolithic Man’, ‘Neolithic Man’, etc., neatly sum up whole periods. When the time comes for anthropologists to turn their attention to the twentieth century, they will surely choose the label ‘Legless Man’. Histories of the time will go something like this: ‘in the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts and escalators in all large buildings to prevent people from walking. This situation was forced upon earth dwellers of that time because of miles each day. But the surprising thing is that they didn’t use their legs even when they went on holiday. They built cable railways, ski-lifts and roads to the top of every huge mountain. All the beauty spots on earth were marred by the presence of large car parks. ’ The future history books might also record that we were deprived of the use of our eyes. In our hurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird’s-eye view of the world – or even less if the wing of the aircraft happens to get in your way. When you travel by car or train a blurred image of the countryside constantly smears the windows. Car drivers, in particular, are forever obsessed with the urge to go on and on: they never want to stop. Is it the lure of the great motorways, or what? And as for sea travel, it hardly deserves mention. It is perfectly summed up in the words of the old song: ‘I joined the navy to see the world, and what did I see? I saw the sea.’ The typical twentieth-century traveler is the man who always says ‘I’ve been there. ’ You mention the remotest, most evocative place-names in the world like El Dorado, Kabul, Irkutsk and someone is bound to say ‘I’ve been there’ – meaning, ‘I drove through it at 100 miles an hour on the way to somewhere else. ’ When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend all experience; the present ceases to be a reality: you might just as well be dead. The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. He experiences the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels a delicious physical weariness. He knows that sound. Satisfying sleep will be his: the just reward of all true travellers. 1 、 Anthorpologists label nowaday’s men ‘Legless’ because A people forget how to use his legs. B people prefer cars, buses and trains. C lifts and escalators prevent people from walking. D there are a lot of transportation devices. 2 、 Travelling at high speed means A people’s focus on the future. B a pleasure. C satisfying drivers’ great thrill. D a necessity of life. 3 、 Why does the author say ‘we are deprived of the use of our eyes’ ? A People won’t use their eyes. B In traveling at high speed, eyes become useless. C People can’t see anything on his way of travel. D People want to sleep during travelling. 4 、 What is the purpose of the author in writing this passage? A Legs become weaker. B Modern means of transportation make the world a small place. C There is no need to use eyes. D The best way to travel is on foot. 5. What does ‘a bird’s-eye view’ mean? A See view with bird’s eyes. B A bird looks at a beautiful view. C It is a general view from a high position looking down. D A scenic place. 查看更多

夹套内置导热油的暴沸问题? 依照你所描述的状况,因该是导热油和水有混合; 1.能否确认反应釜是否有漏; 2.将新油取出一小份检验其水分含量,导热油里不应有这么多水; 3.煮水温度段是105-150度之间,要缓慢,注意观察排空管的出汽和系统的压力状况; 4.你用的是矿物油,就不要全封闭了,矿物油的的杂质太多了需要不断的排气。 最后再给你一个忠告:电加热系统用矿物油,你要对你的电加热棒多加维护。 讨论qq:525224195查看更多
