This was the 37 of my job as a music teacher, I thought -- teaching was not for me. Then I had an idea.

The three letters present viewpoints on _______.A. real source of road dangerB. ways to improve road facilitiesC. measures to punish road offencesD. increased awareness of road rulesBIn its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and cartsgot stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."The city planner decided to build an underground drainage (排水) system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.An engineer named Ellis Chesbrough convinced me the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each sectionof roughly 10 jackscrews. At Pullman's signal each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening. Some people like to say that every problem has a solution.But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to cleanthe polluted river.61. The author mentions the joke to show ______.A. horses were fairly useful in ChicagoB. Chicago's streets were extremely muddyC. Chicago was very dangerous in the springD. the Chicago people were particularly humorous62. The city planners were convinced by Ellis Chesbrough to_______.A. get rid of the street dirtB. lower the Chicago RiverC. fight against heavy floodsD. build the pipes above ground63. The underlined word "hoist" in Paragraph 4 means "_______".A. changeB. liftC. repairD. decorate64. What can we conclude about the moving operation of the Tremont Hotel?A. It went on smoothly as intended.B. It interrupted the business of the hotel.C. It involved Pullman turning ten jackscrews.D. It separated the building from its foundation.65. The passage is mainly about the early Chicago's ______.A. popular life styles and their influencesB. environmental disasters and their causesC. engineering problems and their solutionsD. successful businessmen and their achievementsCHave your parents ever inspected your room to see if you cleaned it properly Imagine having your entire houses, garage, and yard inspected at any time -- with no warning. Inspections were a regular part of lighthouse (灯塔) living, and a keeper's reputation depended on results.A few times each year, an inspector arrived to look over the entirelight station. The inspections were supposed to be a surprise, but keeper sometimes had advance notice.Once lighthouses had telephones, keepers would call each other to warn that the inspector was approaching. After boats began flying special flags noting the inspector aboard, the keeper's family made it a game to see who could notice the boat first. As soon as someone spotted the boat, everyone would do last-minute tidying and change into fancyclothes. The keeper then scurried to put on his dress uniform and cap. Children of keepers remember inspectors wearing white gloves to runtheir fingers over door frames and windowsills looking for dust.Despite the serious nature of inspections, they resulted in some funny moments. Betty Byrnes remembered when her mother did not have time to wash all the dishes before an inspection. At the time, people did not have dishwashers in their homes. In an effort to clean up quickly, Mrs. Byrnes tossed all the dishes into a big bread pan, covered them with a cloth and stuck them in the oven. If the inspector opened the oven door, it would look like bread was baking. he never did.One day, Glenn Furst's mother put oil on the kitchen floor just before the inspector entered their house. Like floor wax, the oil made the floors shiny and helped protect the wood. This time, though, she used a little too much oil. When the inspector extended his hand to greet Glenn's mother, he slipped on the freshly oiled surface. "He came across that floor waving his arms like a young bird attempting its first flight," Glenn late wrote. After he steadied himself, he shook Glenn's mother's hand, and the inspection continued as though nothing had happened.66. What does Paragraph I tell us about the inspection at the light station?A. It was carried out once a year.B. It was often announced in advance.C. It was important for the keeper's fame.D. It was focused on the garage and yard.67. The family began making preparations immediately after ______.A. one of the members saw the boatB. a warning call reached the lighthouseC. the keeper put on the dress uniform and capD. the inspector flew special flags in the distance68. Mrs. Byrnes put the dishes in the oven because this would ______.A. result in some funB. speed up washing themC. make her home look tidyD. be a demand from the inspector69. If the inspector had opened the oven door, he would have seen_______.A. an empty panB. many clean dishesC. pieces of baked breadD. a cloth covering something70. The inspector waved his arms ______.A. to try his best to keep steadyB. to show his satisfaction with the floorC. to extend a warm greeting to Glenn's motherD. to express his intention to continue the inspectionPart IV Writing (45 marks)Section A (10 marks)Directions: Read the following passage. Fill in the numbered blanks by using the information from the passageWrite NO MORE THAN THREE WORDS for each answer.Not all print dictionaries are the same, as you will notice when you select one. To make a wise selection, you should know how to distinguish among three kinds of print dictionaries: pocket, desk, and unabridged. You should also know the copyright date of your dictionary, and check is special features.A pocket dictionary is small. Generally, it contains no more than 75000 entries, making it hardly to carry to class and efficient to use. However, a pocket dictionary doesn't contain enough entries to be adequate for college reference homework. In addition, the information about each word in a pocket dictionary is generally limited. A desk dictionary is medium sized, generally containing over 100,000 entries as well as extra features. For college work, you should own a current desk dictionary. An unabridged dictionary is a complete dictionary. Abridged dictionaries, such as pocket and desk dictionaries, are shortened.Because unabridged dictionaries contain nearly all English words, they are large and heavy. They are often used by schools and libraries.If the copyright date of your current dictionary shows that it was published five or more years ago, consider investing in a more recent edition. English is a dynamic language that admits new words and recognizes changes in meaning, spelling, and usage of familiar words. This is reflected in an up-to-date dictionary.In selecting a dictionary, check the features it offers besides vocabulary definitions. Many editions contain signs, symbols and foreign words. Some also contain CD-ROMs and access to special online features.Section B (10 mark.)Directions: Read the following passage. Answer the questions accordingto the information given in the passage.Walk Out of the Comfort Zone and Try New Things For most high school students, free periods are useless. From what I have seen, few do homework, instead many are on their phones and talking, making it impossible for those who actually want to do work to complete any. As a senior next year, I think extra periods should be used to take optional subjects.Our school offers many classes. Now is the time to experiment in different fields of study. We will never know if we are interested or talented in a subject if we don't try it.In my 8th grade, I was told that I had to take an art class as a graduation requirement; so in the 9th grade I took Studio and Art. One of the projects was to build a clay pot, but I built mine incorrectly, so it broke in the kiln (窑). I found out that I have no artisticability at all, and now I know for sure that I do not want to be an artist. However, the class was one of my favorites that year. I was able to try new activities and test my ability.Walk out of our comfort zone and try new things! College is when we should focus on a specific major, but high school is when we have to figure it out.Half of all college students change their major at some point. By doing that hundreds of dollars are wasted on classes that they would have never needed to take. So use our extra periods to find out what we want to do in college. The classes we choose can impact us in future. Taking optional subjects will enrich our mind. It will also show colleges we are diverse students.81. How should we use our extra periods in the author's opinion?(No more than 9 words) (2 marks)________________________________________________________________________82. Why does the author think we should experiment in different fields of study?(No more than 17 words) (2 marks)________________________________________________________________________ 83. Why did the clay pot show the author's lack of artistic ability (No more than 10 words) (3 marks)________________________________________________________________________ 84.According to the author, how will taking optional subjects impact up in the future(No more than 13 words) (3 marks)________________________________________________________________________ Section C (25 marks)Directions: Write an English composition according to the instructions given below.请以老师当众表扬你为话题，用下面所给的句子开头，续写一篇英语短文。

4月末，规模以上工业企业资产总计923307.7亿元，同比增长7.9%；负债合计528664.6亿元，增长6%；所有者权益合计394643.1亿元，增长10.7%。
4月末，规模以上工业企业应收账款103425.1亿元，同比增长8.6%；产成品存货37160.5亿元，增长7%。
1-4月份，规模以上工业企业主营业务收入利润率为5.27%，每百元主营业务收入中的成本为85.9元，每百元资产实现的主营业务收入为108.1元，人均主营业务收入为107.8万元，产成品存货周转天数为15.4天，应收账款平均回收期为37.1天。
4月末，资产负债率为57.3%。
表1 2015年1-4月份规模以上工业企业主要财务指标
应收账款：指企业因销售商品、提供劳务等经营活动所形成的债权，包括应向客户收取的货款、增值税款和为客户代垫的运杂费。
产成品存货：指企业报告期末已经加工生产并完成全部生产过程，可以对外销售的制成产品。
主营业务收入利润率=利润总额÷主营业务收入×100%，单位：%。
每百元主营业务收入中的成本=主营业务成本÷主营业务收入×100，单位：元。
每百元资产实现的主营业务收入=主营业务收入÷平均资产÷累计月数×12×1 00，单位：元。
人均主营业务收入=主营业务收入÷平均用工人数÷累计月数×12，单位：万元/人。
资产负债率=负债合计÷资产总计×100%，单位：%。
产成品存货周转天数=360×平均产成品存货÷主营业务成本×累计月数÷12，单位：天。
应收账款平均回收期=360×平均应收账款÷主营业务收入×累计月数÷12，单位：天。
在各表的利润总额同比增长栏中，标“注”的表示上年同期利润总额为负数，即亏损；数值为正数的表明利润同比增长；数值为负数且大于等于-100%的表明利润同比下降；数值小于-100%的表明由上年同期盈利转为本期亏损；数值为0的表明利润同比持平。
国有控股企业即原来的国有及国有控股企业。
由于规模以上工业企业范围每年发生变化，为保证本年数据与上年可比，计算各项指标同比增长速度和增长量所采用的同期数与本期的企业统计范围相一致，和上年公布的数据存在口径差异。
2、统计范围
规模以上工业企业，即年主营业务收入为2000万元及以上的工业法人单位。
3、调查方法
规模以上工业企业财务状况报表按月进行全面调查（1月份数据免报）。
4、行业分类标准
执行国民经济行业分类标准（GB/T4754-2011），具体请参见http://www. /tjsj/tjbz/hyflbz
5、随着生产经营模式的不断创新，企业经营日趋多元化，按现行会计准则，越来越难以分离并计算主营活动相关的财务数据。
因此，从2015年起，不再按月发布主营活动利润数据，改为年底一次性推算并发布全年数据。
