Passage 49Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we are often able to know where most words come from. Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers are called hamburgers, especially when they are not made with ham About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces of beef, they asked the Germans what it was. The Germans did not understand the question and answered, "We come from Hamburg." One of these Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburg ate. Then he put them between two pieces of bread and started selling them. Such bread came to be called "hamburgers". Today, "hamburgers" are sold in many countries around the world. Whether this story is true or not, it certainly is very interesting. Knowing why any word has a certain meaning is interesting, too. The explanation, for most English words, can be found in any large English dictionary. According to the author, English is______.
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. Which of the following statements is NOT true

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？
