【文章內容簡介】 9。Your sister will be here in less than an hour and we must be at the station to meet her. We are late already.39。 As she walked away, I followed her out of the fair. Lesson61 Trouble with the Hubble 哈勃望遠鏡的困境In future, astronauts will be required to descend from a spaceship while it is still in space and to return to it. The ability to do this will be necessary in future flights to distant planets. Scientists are now trying to discover if this is possible. The spaceship Astra which left the earth a short time ago, will be travelling three hundred miles into space. At a certain point, the Astra will stop for a short time and an astronaut will attempt to leave the stationary spaceship and then return to it. We shall not know whether the experiment has been successful until we have received a radio message. The first message is expected to arrive at 7 o39。clock this evening. By that time, the Astra will have been flying through space for seventeen hours and will have circled the earth a great many times. When the first radio messages have been received, the results of the trip will be announced immediately.Lesson62 After the fire 大火之后Firemen had been fighting the forest fire for nearly three weeks before they could get it under control. A short time before, great trees had covered the countryside for miles around. Now, smoke still rose up from the warm前 言太陽能產品分兩大類：太陽能光電產品和太陽能光熱產品，而太陽能熱水器是太陽能光熱產品中的一種，也是目前太陽能產品中技術最成熟 、應用最廣泛的一種，具有環(huán)保節(jié)能和安全方便的特點。針對你單位燃氣費年耗費較高，想利用太陽能熱水器節(jié)省一些能源耗費，但又擔心太陽能熱水器不穩(wěn)定，不能保障上萬學生都有熱水使用這一問題，本文先從太陽能技術參數(shù)（產水量、產水溫度、樓面負載），太陽能熱水系統(tǒng)的防凍技術，太陽能熱水系統(tǒng)的輔助加熱設備（即太陽能熱水與常規(guī)加熱設備的切換）幾方面闡述，希望能夠讓各位了解太陽能中央熱水系統(tǒng)完全能保障上萬人都有熱水使用；接著從太陽能熱水器的社會效益、經濟效益、投資及回報率、太陽能的運行費用及維護費用幾方面闡述，希望能夠讓各位了解太陽能熱水系統(tǒng)應該并且值得投資。再闡述選擇太陽能熱水系統(tǒng)的幾個要素希望能夠讓各位了解如何選擇太陽能熱水系統(tǒng)，最后簡介我們公司、公司系列產品并附部分客戶名錄及客戶的評價，希望能夠讓各位初步了解我們公司是你們單位值得長期合作的伙伴，并進一步參觀考察我們公司。不敢期望以上目的全部達到，對于您能夠在百忙中抽出寶貴時間來詳閱本文，在此我表示誠摯的謝意﹗五星太陽能公司 張輝2003年12月5日目 錄一、太陽能熱水器技術參數(shù)二、太陽能中央熱水系統(tǒng)的防凍 三、太陽能中央熱水系統(tǒng)及輔助加熱設備 四、太陽能熱水器的社會效益 五、太陽能熱水器的經濟效益六、太陽能熱水器的投資及回報率七、太陽能系統(tǒng)的運行費用及維護費用八、太陽能熱水系統(tǒng)的選擇太陽能集熱器選擇運行方式的選擇輔助加熱設備的選擇回水系統(tǒng)的選擇配套節(jié)水設施的選擇——IC卡節(jié)水收費系統(tǒng)合作廠家的選擇九、五星太陽能公司簡介十、五星太陽能公司系列產品附錄五星太陽能公司部分客戶名錄附錄武漢理工大學在“湖北高等院校太陽能中央熱水系統(tǒng)現(xiàn)場會”的發(fā)言附錄客戶反饋意見24while she was having a piic at the edge of a forest with her children and tried to steal her handbag. In the struggle, the strap broke and, with the bag in their possession, both men started running through the trees. Mrs Sterling got so angry that she ran after them. She was soon out of breath, but she continued to run. When she caught up with them, she saw that they had sat down and were going through the contents of the bag, so she ran straight at them. The men got such a fright that they dropped the bag and ran away. 39。The strap needs mending,39。 said Mrs Sterling later, 39。but they did not steal anything.39。Lesson45 A clear conscience 問心無愧The whole village soon learnt that a large sum of money had been lost. Sam Benton, the local butcher, had lost his wallet while taking his savings to the postoffice. Sam was sure that the wallet must have been found by one of the villagers, but it was not returned to him. Three months passed, and then one morning, Sam found his wallet outside his front door. It had been wrapped up in newspaper and it contained half the money he had lost, together with a note which said: 39。A thief, yes, 39。but only 5o per cent a thief!39。 Two months later, some more money was sent to Sam with another note:39。 Only 25 per cent a thief now!39。 In time, all Sam39。s money was paid back in this way. The last note said:39。 I am 100 per cent honest now!39。lesson46 Expensive and unfortable 既昂貴又受罪When a plane from London arrived at Sydney airport, workers began to unload a number of wooden boxes which contained clothing. No one could account for the fact that one of the boxes was extremely heavy. It suddenly occurred to one of the workers to open up the box. He was astonished at what he found. A man was lying in the box on top of a pile of woollen goods. He was so surprised at being discovered that he did not even try to run away. After he was arrested, the man admitted hiding in the box before the plane left London. He had had a long and unfortable trip, for he had been confined to the wooden box for over ten hours. The man was ordered to pay amp。345 for the cost of the trip. The normal price of a ticket is amp。230 !Lesson47 A thirsty ghost 嗜酒的鬼魂A public house which was recently bought by Mr Ian Thompson is up for sale. Mr Thompson is going to sell it because it is haunted. He told me that he could not go to sleep one night because he heard a strange noise ing from the bar. The next morning, he found that the doors had been blocked by chairs and the furniture had been moved. Though Mr Thompson had turned the lights off before he went to bed, they were on in the morning. He also said that he had found five empty whisky bottles which the ghost must have drunk the night before. When I suggested that some villagers must have e in for a free drink, Mr Thompson shook his head. The villagers have told him that they will not accept the inn even if he gives it away. Lesson48 Did you want to tell me something? 你想對我說什么嗎？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 cottonwool. He knew I collected birds39。 eggs 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 cottonwool from my mouth, I was able to tell him that he had pulled out the wrong tooth.
