Joe Biggs was a butcher(卖肉者). His shop was in a village in one of the most beautiful parts of the south of England, and he worked in the shop for many years while his father was there. Then, when his father reached the age of 65, he stopped working in the shop, and Joe was alone in it, so he had to work harder.
Joe worked for five and a half days a week. His shop shut at one o’clock on Thursday, and it was shut the whole of Sunday. Saturdays were the busiest days.
Most of Joe’s meat came to his shop from the nearest town, but sometimes he got up earlier than usual in the morning and drove to the city to choose meat. It was cheaper there.
Joe had a big refrigerator(电冰箱) in his shop, but he tried not to buy too much meat at a time, and to sell it before he bought more.
One Thursday a woman came into the shop at five minutes to one. “I’m sorry I’m late,” she said, “but some people just called me. They say they will come to dinner tonight, and I need some more meat.”
Joe had only one piece of good meat left in the shop. He sold all the others earlier in the day. He took the piece out and said to the woman, “This is ￡6.50.”
“That piece is too small,” the woman answered. “Do you have a bigger piece?”
Joe went into the room behind his shop, opened the refrigerator, put the meat into it, took it out again and shut the door of the refrigerator with a lot of noise. Then he brought the piece of meat back to the woman and said. “ This piece is bigger and more expensive. It’s ￡8.75.”“Good,” said the woman with a smile. “Give me both of them, please.”
71)Why did Joe have to work harder now?
A. Because there were more butcher’s shops in the village.
B. Because more people came to his shop.
C. Because he now worked for more days.
D. Because his father stopped working with him.
72)When did Joe usually buy his meat?
A. In the morning.
B. On Thursday afternoon.
C. On Saturday.
D. On Sunday.
73)Where did Joe usually buy his meat?
A. From the farmers.
B. At the village market.
C. At the nearby town.
D. At the big city
74)Why didn’t Joe have much meat in his shop?
A. He had many customers that day.
B. He forgot to go to buy some meat.
C. He had no place to keep the meat.
D. He didn’t buy enough meat.
75)What did Joe take from his refrigerator?
A. A bigger piece of meat.
B. A cheaper piece of meat.
C. A more expensive piece of meat.
D. The same piece of meat.

The longest crocodile people have ever caught died on February 10, 2013 in a crocodile park in Philippines. The monster called Lolong was 20 feet 3 inches long and weighed 1,057 kilos when people caught it.
Before people found Lolong, they thought the longest crocodile was one named “Cassius”which lived in Australia.
Australia kept it in a crocodile park. Cassius was 17 feet 11.75 inches long and weighed 970 kilos. People think Lolong was dangerous. They believed that it was the reason for the disappearances of a girl in 2009 and later a fisherman in 2011 and some cows in the far-away village in Philippines. It took three weeks to find the dangerous crocodile and around 100 people to bring it onto land.
The reason of Lolong’s death is not yet clear. Some think it was because of the cold weather, others say it was because Lolong ate some bad food. People also found a rope in Lolong’s stomach after its death and they think that’s why the animal ate so little and stopped eating at the end of its life. Scientists believe that huge crocodiles like Lolong live up to 100 years. Lolong was 7 when it died.
The crocodile park will keep Lolong’s body on display(展览) as Lolong was the star of its crocodile show and brought thousands of tourists to the park.
76)The crocodile name Lolong was ______ than the one named Cassius.
A.heavier
B.lighter
C.shorter
D.taller
77) People believed that Lolong once killed__________.
A.about 100 people
B.about 100 cows
C.a girl, her parents and their cows
D.a girl, a fisherman and some cows
78)People found Lolong_______ before they caught it.
A.on land
B.on the grass
C.in the forest
D.in water
79) Which of the following is not mentioned(提到) as a possible reason for Lolong’s death?
A. The cold weather.
B. The rope in its stomach.
C. The large number of the tourists.
D. Eating bad food.
80)Which of these is true?
A. People can’t see Lolong’s body any more.

“I would rather have cheese than any other food,”he said. “Bring me more cheese!”His cooks make him many different kinds of cheese. The king ate a lot every day and kept a lot in his palace.

A题设计一个交通环岛 在许多城市和社区都建立有交通环岛，既有多条行车道的大型环岛（例如巴黎的凯旋门和曼谷的胜利纪念碑路口），又有一至两条行车道的小型环岛。有些环岛在进入口设有“停车”标志或者让行标志，其目的是给已驶入环岛的车辆提供行车优先权；而在一些环岛的进入口的逆向一侧设立的让行标志是为了向即将驶入环岛的车辆提供行车优先权；还有一些环岛会在入口处设立交通灯（红灯会禁止车辆右转）；也可能会有其他的设计方案。 这一设计的目的在于利用一个模型来决定如何最优地控制环岛内部，周围以及外部的交通流。该设计的目的在于可利用模型做出最佳的方案选择以及分析影响选择的众多因素。解决方案中需要包括一个不超过两页纸，双倍行距打印的技术摘要，它可以指导交通工程师利用你们模型对任何特殊的环岛进行适当的流量控制。该模型可以总结出在何种情况之下运用哪一种交通控制法为最优。当考虑使用红绿灯的时候，给出一个绿灯的时长的控制方法（根据每日具体时间以及其他因素进行协调）。找一些特殊案例，展示你的模型的实用性。 标题：一个环来控制一切:优化交通圈。 安德里亚?利维亚伦 安德烈娅?利维 拉塞尔?梅里克 哈维姆德学院 顾问:苏珊 摘要 我们的目的是利用车辆动力学考虑在圆形交叉路口的道路情况。我们主要根据进入圆形道路的速度决定最好的方式来控制车流量。我们假设在一个车道通过圆形道路循环，这样交通输入量能够被调节。（也就是，不会有优先的交通输入量） 对于我们的模型，可改变的参数是排队等候进入的速率，进入圆形道路的速率（服务速率），这个圆形道路最大的容量和离开这个道路的速率。我们使用带有队列和交通圈的隔室模型作为隔间。来自外界的车辆首先进行排队等候，然后进入圆环交叉路口，最后离开到外界。我们把服务速率和离开速率作为在圆环交叉路口的车辆数量参考。 另外，我们利用计算机来拟态一个可见表示，发生在不同情形下的圆环交叉路口。允许我们检验不同的情况，例如不平等的交通流量由于不同的队列，一些十字路口比其他车辆有一个更高的概率。这个拟态模仿实施栩栩如生，例如如何当前面是空道路时进行加速，而当前面有其他车辆时进行减速。大多数情况下，我们发现：一个高服务效率能够保持交通顺畅的最佳方式，这意味着对于进入交通的效率是最有效的。然而，当交通变得拥堵时，较低的服务率更好的适应了交通，这指示应该使用一个红绿灯。所以，在不同时间段，依靠预测中的交通流量，一个信号灯应该被安装进行循环实现。

介绍 今年的焦点问题是如何实现质量和数量的平衡。 在质量方面，尽可能使热量均匀地分布。目标是降低或避免矩形烤盘四个边角发生热量聚集的情况。所以解决热量均匀分布这方面的问题，使用圆形烤盘是最佳的选择。 在数量方面，应该使烤盘充分的占据烤箱的空间。所以我们的目的是使用尽可能多的烤盘来充分占据烤箱的空间，此时矩形烤盘是最佳选择。对于这方面的问题的解决，就要考虑烤盘在烤箱水平截面上所占的比率。 在这个评论中，我们首先描述判断步骤，然后再讨论队伍对于三个问题的求解。下一个话题就是论文的灵敏度和假设，紧随其后讨论确定一个给定方法的优势和劣势。最后，我们简短的讨论一下参考和引用之间的区别。 过程 第一轮的判别被称为“分流轮”。这些初始轮的主要思想是确定论文应被给予更详细的考虑。每篇论文应该至少阅读两次。在阅读一篇论文的时候，评审的主要问题是论文是否包含所有必要的成分,使它成为一个候选人最详细的阅读。在这些初始轮中，评审的时间是有限制的，所以我们要尽量让每一篇论文得到一个好的评判。如果一篇论文解决了所有的问题，就会让评审觉得你的模型建立是合理的。然后评审可能会认为你的论文是值得注意的。有些论文在初轮评审中可能会得到不太理想的评论。 特别值得注意的是，一篇好的摘要应该要对问题进行简要概述，另外，论文的概述和方法，队员之间应该互相讨论，并且具体的结果应该在某种程度上被阐述或者表达出来。在早期的几轮中，一些小细节能够有突出的表现，包括目录，它更便于评委看论文，同时在看论文的时候可能会有更高的期待。 问题求解也很重要。 最后，方法和结果要清晰简明的表达是至关重要的。 另外，在每个部分的开始，应该对那个部分进行一个概述。 在竞赛中，建模的过程是很重要的，同时也包括结论的表达。如果结果没有确切和充分的表达，那么再好的模型和再大努力也是没有用的。 最后的回合 最后一轮阅读的第一轮开始于评委会会议。在这个会议中，评委将进行讨论，他们会分享他们各自认为的问题的关键方面。然后每个评委阅读大量的论文。这些论文来自以前判断轮中平均分配的，论文的分数是各种各样从低到高排列的。 这些论文检查结束之后，评委们又聚到一起讨论，讨论他们认为一篇好的论文应该包括什么。评委们都知道团队们要在限制的时间里完成比赛，这额外的步骤的目的是补偿队伍的局限性和限制强迫队里的成员。 一旦评委同意了一套最低标准，最后回合开始。每一篇论文都被阅读很多次。随着回合的进展，论文的数量逐渐减少，条目越来越多地受到审查.。此外，投入每一篇论文的时间持续上升，在最后一轮，论文仍然是给予最高水平的关注。评审花在论文上的时间增加了，多个评委可以同时阅读同一份论文的复印件.。到了这个时候，论文通常保持优秀的摘要和良好的书面。然后，评委完全集中在建模过程和数学完整性的论文上。 问题 今年的问题可以归结于三个不同的问题。 第一个问题是确定一个给定形状的布朗尼烤盘的热分布情况。

2019MCM Problem A:A Hot Youbot Background:Thermal Analysis,using finite element techniques,is carried out as a steady-state or transient analysis.Conductive heat transfer is handled directly by finite element techniques; conduction occurs in a solid due to temperature differences.However,radiation heat transfer analysis may require additional particle-tracking or ray-tracing techniques to approximate the radiant energy arriving at a given surface. The material is assumed to be a magnesium alloy and to have a thermal conductivity of52W/m?K. Material properties were taken from"Thermal Conductivity of Magnesium Alloys".Since the model is in inches you can use symunit to rewrite the value in inches.Now you need remove the units to obtain the value for the thermal properties.Unless overwritten,all of the side faces are set to have a natural convection coefficient of25W/m2?K representing heat transfer to an ambient air temperature of288.15K(25℃).Convert and calculate the convection coefficient to W/inch2?K to be consistent with the model dimensions. Explore different material selections for the robotic https://www.doczj.com/doc/2c13040475.html,pute the change in max body temperature as a function of increasing thermal conductivity.Before begining calculate the expected run time from the previous run time.Run the models using a parfor loop to speed up the simulation by parallelizing the iterations across Parallel Computing Toolbox workers.If you do not have the Parallel Toolbox change parfor to for. Problem: Part I:Develop a mathematical model for the heat transfer among the gripper pivot.In the youBot,the gripper pivot sits underneath the electronics board and is exposed to the heat coming off the circut board.Here you will create the pde model,import the STL file of the gripper pivot, and plot it.Create and visualize a tetrahedral mesh of the component with a maximum value of 0.09inches.Measure the x,y and z dimensions of the mesh. Part II:The bottom face is given a fixed temperature assuming that the rest of the robotic arm acts as a heat sink.The top face and inner hole is arbitrarily given a heat flux to represent the heat off the circuit board.Solve the model and calculate the max and bulk body temperatures and time how long the solve https://www.doczj.com/doc/2c13040475.html,pute the max temperature in K and rewrite that to℃and F,then plot the distribution of temperature of the gripper pivot in3D. Part III:Develop a mathematical model for predicting the relationship between thermal conductivity and max temperature for this geometry and material.Assume the robotic arm shuts off at a max temperature of311K,find the associated allowable heat transfer coefficient for the alloy.Which materials are appropriate for being made into the the gripper pivot? Part IV:Prepare a short(1to2pages)synopsis of your results suitable for publication as a short note in IEEE Communications Magazine. Your submission should consist of: ●One-page Summary Sheet, ●Two-page synopsis,
E题解法思路，2018年美赛题 采用气候统计模型 此题容易获奖，只要在网上收集世界各国的GDP，人口，气温，降水，粮食产量等数据，建立统计回归模型，就能解决下面的几个问题。 任务1：开发一个模型来确定一个国家的脆弱性，同时测量气候变化的影响。您的模型应该识别一个状态是脆弱的、脆弱的还是稳定的。它还应查明气候变化如何通过直接手段或间接影响脆弱性，因为它影响其他因素和指标。 解法思路，采用气候脆弱性统计模型 任务2：选择的前10名最脆弱国家的脆弱状态指标确定（https://www.doczj.com/doc/2c13040475.html,/fsi/data/）和确定了气候变化可能对国家的脆弱性增加。使用你的模型来显示，如果没有这些影响，状态可能会更脆弱。 解法思路，采用最脆弱气候统计模型 任务3：把你的模型运用到另一个不在前10位的状态来衡量它的脆弱性，看看气候变化会以什么方式以及何时促使它变得更脆弱。确定任何明确的指标。你如何定义一个临界点并预测一个国家什么时候能到达它？解法思路，采用脆弱气候统计模型 任务4：用你的模型说明哪些国家驱动的干预措施可以减轻气候变化的风险，防止一个国家成为脆弱的国家。解释人类干预的效果并预测该国干预的总成本。 解法思路，采用干预气候统计模型 任务5：您的模型将在较小的“国家”（如城市）或更大的“国家”（如大洲）上工作吗？如果没有，您将如何修改您的模型？ 解法思路，采用局部气候统计模型 2018 ICM 问题E：气候变化如何影响区域不稳定？ 气候变化的影响，包括增加的干旱、冰川萎缩、动植物范围的变化以及海平面的上升，已经开始实现，并因地区而异。政府间气候变化专门委员会指出，气候变化的净破坏成本可能是显著的。许多这些影响将改变人类的生活方式，并有可能导致社会和政府结构的削弱和崩溃。因此，不稳定的政府，可能导致脆弱的国家。 脆弱的国家是国家政府不能或不愿意为其人民提供基本必需品的地方。就这个问题而言，“国家”指的是一个主权国家或国家。作为一个脆弱的国家，增加了一个国家人口遭受自然灾害、减少耕地、不可预测的天气和气温升高等气候冲击的脆弱性。不可持续的环保措施，迁移，和资源短缺，这是常见的在发展中国家，可能进一步加剧，国弱治理（施瓦兹和兰达尔，2003；gleditsch特性，并buhaug，2013）。可以说，叙利亚和也门的干旱进一步加剧了已经脆弱的国家。环境压力本身并不一定引发暴力冲突，但有证据表明，当它与薄弱的治理和社会分裂相结合时，它能引发暴力冲突。这种融合可以提高暴力的恶性循环，通常沿潜在的民族和政治分歧（krakowka，Heimel，和加尔加诺2012）。 您的任务如下： 任务1：开发一个模型来确定一个国家的脆弱性，同时测量气候变化的影响。您的模型应该识别一个状态是脆弱的、脆弱的还是稳定的。它还应查明气候变化如何通过直接手段或间接影响脆弱性，因为它影响其他因素和指标。
