2018年10月20日中国大陆雅思考区雅思A类笔试真题回忆+答案汇总 回忆1： 听力 s1 保险理赔吧 s2 在阳台种菜 s3 学生教授讨论修马路 s4 澳大利亚 海豚 阅读：衣服材料，语言考古，桥梁检测技术 回忆2： 小作文柱图，对三个医院不同方面满意的调查结果。 大作文，maintain museums to the public越来越贵，有啥解决的办法么，（政府，公司和个人） 回忆3: 大作文给博物馆funding最好的办法，给了三个例子，business，government，individuals，小作文柱状图 回忆4： 阅读： P1讲的是一个人发明了一种检验桥梁损伤的机器。 P2讲的是用来做衣服的复合纤维，也属于科技类的。 P3讲的是1980年一个人提出了本土英语语言学的研究并把它分了不同的group，社会上很多这方面研究的学者对他的这个报告有很多的质疑。然后每个学者都从不同的角度和历史讲了自己的观点 回忆5： 阅读 第一篇：桥梁检测技术 （Keep a watchful eye on the bridges ） 文章大意：关于如何利用技术来鉴定桥梁的损坏程度。文章涉及到10年来桥梁的状况, 以及LA大学的研究成果，如何利用声纳来检测桥梁的损坏程度， 他们新发明的装置如何安装，如何测量等, 及对未来发展的美好展望 原文： A Most road and rail bridges are only inspected visually, if at all. Every few months, engineers have to clamber over the structure in an attempt to find problems before the bridge shows obvious signs of damage. Technologies developed at Los Alamos National Laboratory, New Mexico, and Texas A&M University may replace these surveys with microwave sensors that constantly monitor the condition of bridges.
B “The device uses microwaves to measure the distance between the sensor and the bridge, much like radar does,” says Albert Migliori, a Los Alamos physicist “Any load on the bridge – such as traffic induces displacements, which change that distance as the bridge moves up and down.” By monitoring these movements over several minutes, the researchers can find out how the bridge resonates. Changes in its behaviour can give an early warning of damage.
C The Interstate 40 bridge over the Rio Grande river in Albuquerque provided the researchers with a rare opportunity to text their ideas. Chuck Farrar, an engineer at Los Alamos, explains: “The New Mexico authorities decided to raze this bridge and replace it. We were able to mount instruments on it, test it under various load conditions and even inflict damage just before it was demolished.” In the 1960s and 1970s, 2500 similar bridges were built in the US. They have two steel girders supporting the load in each section. Highway experts know that this design is “fracture critical” because a failure in either girder would cause the bridge to fail.
D After setting up the microwave dish on the ground below the bridge, the Los Alamos team installed conventional accelerometers at several points along the span to measure its motion. They then tested the bridge while traffic roared across it and while subjecting it to pounding from a “shaker”, which delivered precise punches to a specific point on the road.
E “We then created damage that we hoped would simulate fatigue cracks that can occur in steel girders,” says Farrar. They first cut a slot about 60 centimetres long in the middle of one girder. They then extended the cut until it reached the bottom of the girder and finally they cut across the flange – the bottom of the girder’s “I” shape.
F The initial, crude analysis of the bridge’s behaviour, based on the frequency at which the bridge resonates, did not indicate that anything was wrong until the flange was damaged. But later the data were reanalysed with algorithms that took into account changes in the mode shapes of the structure – shapes that the structure takes on when excited at a particular frequency. These more sophisticated algorithms, which were developed by Norris Stubbs at Texas A&M University, successfully identified and located the damage caused by the initial cut.
G “When any structure vibrates, the energy is distributed throughout with some points not moving, while others vibrate strongly at various frequencies,” says Stubbs. “My algorithms use pattern recognition to detect changes in the distribution of this energy.” NASA already uses Stubbs’ method to check the behaviour of the body flap that slows space shuttles down after they land.
H A commercial system based on the Los Alamos hardware is now available, complete with the Stubbs algorithms, from the Quatro Corporation in Albuquerque for about $100,000. Tim Darling, another Los Alamos physicist working on the microwave interferometer with Migliori, says that as the electronics become cheaper, a microwave inspection system will eventually be applied to most large bridges in the US. “In a decade I would like to see a battery or solar-powered package mounted under each bridge, scanning it every day to detect changes,” he says.

2018年10月13日雅思考试总体反馈：2018年10月13日听力命中三部分旧题，命中大小作文、命中阅读至少两篇、命中口语大部分真题原题，10月13日雅思听说读写全面大中，A类G类全面开花！（考生回忆不够齐全，待补充，还在不断更新中…）祝贺IRP会员将出现不少雅思高分人才！总体反馈请复制链接进入
特别提醒：雅思考试20多年来，有非常严格的规律性和出题思路。全世界有6大考区，而只有一个剑桥考试中心几个人在出题，每个考区一周平均要出一份考卷，一个月出24份考卷，考官如何保证达到难度一样呢，如何保证新题难度、准确度和评价机制公平呢，所以只能是20年来的题库旧题目的有效组合，新题不能超出5-10%,每份雅思卷子都是95%-99%以上旧题原题真题。多年雅思考官和专家Edward老师非常熟悉雅思出题规律和听说读写题库出题组合卷子的秘诀，IRP资料因此而诞生！具体请阅读http://bbs.ieltstofelglobal.com/thread-32-1-1.html
