题目内容
某市拟建一工业项目，年生产能力为500万吨某产品。同类型年产400万吨的已建项目设备投资额为800万元，且该已建项目中建筑、安装及其他工程费用占设备费的百分比分别为40%、15%、10%，相应的综合调价系数分别为1.08、1.1、1.01。公司董事会决定：资本金投资占60%，负债(贷款)投资占40%，建设期为3年。建设期投资安排为：第一年投资额为30%，第二年投资额为40%，第三年投资额为30%；其中第一年贷款资金占贷款总额的30%，第二年占40%，第三年占30%。该项目在实施过程中，为了确定其预算造价，某分部分项工程在现行定额中无此项目，也不符合定额换算条件。经测算与分析：①人工消耗：基本用工14.5工日/10m2，其他用工占总用工的12%；②材料消耗：650kg/10m2，损耗率为1.8%；③机械消耗：5台班/10m2；④预算价格：人工工日单价22元/工日，主材费用18.5元/kg，其他材料费9.5元/10m2，机械台班单价250元/台班。 1．一个建设项目的投资估算造价是由哪些投资构成的？2．已知生产能力指数n=0.7，综合调价系数f=1.15，则该项目的设备投资额为多少万元？3．拟建项目的总投资额为多少万元？4．建设期的贷款利息为多少万元已知贷款利率为10%。5．涨价预算费为多少万元已知建设期内年平均价格上涨3.3%。6．实施过程中某分项工程的补充定额单价为多少元？

Passage 41 Three men got to the Dover Railway Station a few minutes after nine o’clock one evening. They asked a guard, "What time is the next train for London" The guard said, "You’ve just missed one. A train goes every hour. The next one is at ten o’clock." "That’s all right," they said. "We’ll go and have a drink." So off they went to a bar. A minute or two after ten o’clock they came running and asked the guard. "Has the train gone" "Yes," the guard said. "It went at ten, and I told you. The next one is at eleven o’clock." "That’s all right," they said again. "We’ll go and have another drink." So they went back to the bar. They missed the eleven o’clock train in the same way. Then the guard said, "No, the next train is the last one. If you miss that train, you won’t get to London tonight." (41) Twelve o’clock came, and the last train was just starting out when the three of them came out of the bar running as fast as they could. Two of them got on the train just as it was leaving but the third one didn’t run fast enough, and the train went out leaving him behind. He stood there looking at the train and laughing, as if to miss a train was the best joke in the world. The guard went up to him and said, "I told you that this was the last train. Why didn’t you come earlier" The man kept laughing until tears came into his eyes. Then he caught hold of the guard and said, "Did you see the two men get into the train and leave me here" "Yes, I did." "Well, I was the only one to leave for London. They were here only to see me off!" The three men missed the train______.
Passage 39 Many people have difficulty in studying mathematics. Sometimes their difficulty stems from the psychological idea that they are "not good at math". (39) It has been demonstrated that many times that it is often this idea that is causing their problems rather than any lack of skill in mathematics. The best way to deal with this problem is to tell yourself that math involves using the same numbers you have been using all your life and that you know them as well as anyone else. Then set your mind to learning how they are used in the particular part of mathematics you are studying. Many schools offer "math anxiety" courses which are designed to help people overcome their fear of math. Another problem many people encounter is that in mathematics, unlike some other subjects you may have studied, the material has a very important sequence or order. If you do not understand a section of mathematics text, it is no use going on to the next section. Many sections of math books are based on information presented earlier, so it is essential that you understand a section before going on to the next. Sometimes students in mathematics courses do not read the written material in the text but assume that the instructor will tell them what they need to know. This can cause them serious problems, since many instructors assume that students have read the text before coming to class. The written sections of mathematics textbooks contain much valuable information. "Math anxiety" courses are designed to help you______.
Passage 48 Do you find that getting up in the morning is so difficult that it’s painful This might be called laziness, but Dr. Newman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labor through your work, you may say that you are "hot". That’s true. The time of day when you feel the most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: "Get up, John! You will be late for work again!" The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. (48) Much family quarreling ends when husbands and wives realize what these energy cycles mean, and what cycle each member of the family has. You can’t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Newman believes. Maybe you’re sleepy in the evening but feel that you must stay up late anyway. Counteract (对抗) your cycle bit by bit by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won’t change your cycle, but you’ll get up energetically and work better at your low point. Try to save your energy. Get up with an easily yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do usual work in the afternoon and save tasks requiring more energy for your sharper hours. If a person finds getting up early a problem, most probably______.
Passage 42 Some countries have large numbers of earthquakes. Japan is one of them. Others do not have many; for example, there are few earthquakes in Britain. There is often a great noise during an earthquake. The earth shakes. Houses fall down. Railway lines are broken. Sometimes many people are killed in an earthquake. Earthquakes often happen near volcanoes, but this is not always true. The centers of some are under the sea. The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast is shaken and great waves appear. These waves travel long distances and rush over the land when they reach it. (42) They are strong enough to break down houses and other buildings; sometimes they break more buildings than the earthquake itself. What kind of buildings stands up best in an earthquake A building with concrete walls is perhaps the best. A steel frame will make it even stronger. The frame holds the different parts together, and the walls do not easily fall. There is less chance of fire because concrete and steel do not burn. This kind of building is the safest. Which of the following shows that an earthquake happens
