航空维修系统工程试卷2009-A(答案)

航空维修系统工程试卷A（答案） 一、填空题（每空1分，共27分）把答案写在横线上的空白处。 1．春秋战国时代的《孙子兵法》是一部闪烁着军事系统思想的不朽著作。 2．耗散结构的概念是比利时布鲁塞尔学派领导人普利高津教授于1969年提出来的。 3．早期的维修体制一般只有两级，即一个由一名机械师所负责的地勤机组和一个修理厂。 4．所谓系统，泛指根据某种性质联系在一起的要素的集合。 5．系统要素的联结关系有单向联结和双向联结两种形式。 6．所谓不良结构，也称软系统，是一种偏于社会，机理不甚清楚的生物型系统，很难用数学模型来表示，往往只能用半定量、半定性甚至只能用定性的方法来研究。 7．航空维修是保持和恢复航空技术装备可靠性，发挥装备最佳战术、技术性能所采取的一切措施的总称，它是一个复杂的动态过程。 8．管理过程与技术过程最佳的有机的辩证统一，是科学维修的基本特征，通过抓管理过程去适应技术过程，促使技术过程不断发展，维修的质量和效率才能得到提高。 9．维修实践表明，在同样的条件下，维修能动性发挥得如何，所产生的维修效果也截然不同。 10．模型实质上是一种精简工具，它通过对客观实体系统的形态特征、要素联结的方式、行为变化规律等的模仿，使系统由实体转变为一种抽象表述，从而达到研究系统的目的。 11．模拟方法的发展过程，大致经历了直观模仿、模拟试验和功能模拟三个阶段。 12．系统模型具有预测性、经济性和安全性的特点。 13．人的行为的产发，与人拥有各种各样的需要是分不开的。 14．维修系统工程的任务之一就是合理地安排和使用人力资源，发挥维修人员的最大潜能，提高维修工作的效率和质量。 15．人的情绪、体力和智力等在一个月左右的时间里也有周期性的变化，这些较长期的变化叫生物节律。 16．一个系统从建立到完善，一般要经过可行性论证、方案设计、系统建立、系统运行、系统评价和系统优化几个阶段。 17．现代维修已成为一个复杂的系统，因而系统的优化，必须进行全局性的综合研究，全局问题是维修系统目标依据之所在。 18．维修差错的本质就是维修行为偏差，即维修活动中发生与维修目标的要求相背离的行为。 19．现代航空维修是以可靠性为中心思想的维修，可靠性信息是一种质量信息，它对维修系统的管理起着独特的作用。 20．所谓MIS的质量应该是指所运行的MIS对其全部的功能目标满足程度及其运

《英语教学法》期末考试A卷 BB

▆ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ▆ 《英语教学法》 试卷 共2页（第 1 页） 答案务必写在答题纸上，否则不得分，超出黑色边框区域的答案无效！ ▆ 《英语教学法》期末考试A 卷 开卷 考试时间90分钟，答题卡作答 姓名： 专业： 学号： 学习中心： 缺考标记，考生禁填！ □ 成绩： 一、名词解释（答案务必写在答题纸上，40分） 1. 教学资源 答：教学资源是为教学的有效开展提供的素材等各种可被利用的条件，通常包括教材、案例、影视、图片、课件等，也包括教师资源、教具、基础设施等，广义也应该涉及到教育政策等内容。 2. 英语写作策略 答：是学生学习英语和培养语言能力的主要内容,教师应充分利用教材内容,由浅入深,由简到繁,指导学生进行多种形式的写作训练. 3. 教学设计 答：是根据课程标准的要求和教学对象的特点，将教学诸要素有序安排，确定合适的教学方案的设想和计划。一般包括教学目标、教学重难点、教学方法、教学步骤与时间分配等环节。 4. 发现式教学法 答：亦称假设法和探究法，这是一种基于问题学习的教学方法，是指教师在学生学习概念和原理时，不是将学习的内容直接提供给学生，而是向学生提供一种问题情境，只是给学生一些事实（例）和问题，让学生积极思考，独立探究，自行发现并掌握相应的原理和结论的一种方法。 二、论述题（答案务必写在答题纸上，30分） 1. PWP 教学过程的本质特征是什么？ 答：英语阅读教学中的PWP 过程指的是将整个学习过程分为学习前（pre-learning ）、学习中（while-learning ）和学习后（post-learning ）三个阶段。PWP 模式简洁实用,对促进教师的＂教＂与学生的＂学＂有很大作用。关键是在新课标下如何运用 PWP 来整合课程内容资源,使阅读教学简约高效。 2. 英语教学中如何进行教材的整合。请举例说明。 答：人教版《普通高中课程标准实验教科书》中每一个模块的每个单元都围绕一个主要话题开展听、说、读、写活动，各个部分的教学目标明确，不分课次和顺序，方便教师根据教学的实际情况灵活使用教材。在实际教学中，教师可以充分抓住教材的话题功能这一特点，对教材进行适当的整合，以学生以往的学习经验和知识为基础，恰到好处地对教学目标进行调试，对教学方法进行设计，从而使学生获得更大的学业进步。教材整合有利于教师因材施教，提高学生的学习效率，体现学生为主体、教师为主导的课堂教学方式，同时还可以开发教学资源，使教学具有灵活性、开放性和拓展性，方便学生更好地发挥潜能，提高教师的课程意识和专业素养，从而提高整体教学效果。 1文献综述 在知网查询了相关资料发现：董艳丽在英语教学设计中如何整合教材中，主要讲述了英语较教材模块之间的整合以及教材整合的原则;周金妹在教材整合在初中英语教学中的运用中提出，教材英语教学内容、学生学情相整合;林华英在整合英语教材，提高教学实效中，从宏观上提出了教材整合的策略;梁银碧在整合教材给学生轻松英语课堂中提出从学生的角度进行教材的整合。笔者认为，教材整合不单单是单元模块间的整合，还应该是一学期的教材整合，学年与学年间教材的整合，还应考虑小学、初中、高中教材的衔接性问题，并根据地区间差异进行教材整合。 2教材整合 2.1教材整合概念的提出 在2011年义务教育英语课程标准中提出教材整合的概念，其指出：“教材是实现教学目标的重要材料和手段，教师要善于根据教学的需要，对教材加以适当的取舍和调整。” 2.2教材整合的必要性 教材整合可以提高学生的学习效率。兴趣是最好的老师，如果在教学过程中教师只按照教材内容的顺序传授知识不进行相关补充，很可能会导致学生丧失学习兴趣，并影响学生学习的主观能动性。教师合理地对教材进行调整、扩展 、重新组合，在调动学 生兴趣的前提下，挖掘教材深层次的的内涵，这样会激发学生学习兴趣，并且有效提高学生的学习效率和学习的积极性。 教材整合可以帮助学生形成一套英语学习体系。在传统教学中，教师注重知识的传授，并不注重学生的创造性思维的发展和逻辑思维能力的培养，如果在教学过程中教师对教材进行整体把握，重难点分明，可能训练学生的逻辑思维能力，并生成由易到难，由简入繁的学习体系。 教材整合有利于激发学生学习的主动性。我们的教学活动的中心就是学生，学生是学习的主体，以学生的需求、兴趣、爱好进行重组教材并在教学过程中了解学生的需要，学习中困惑点，以此来扩展调整教材可以让学生投入到课堂中来，提高学生学习的主动性，让每个学生都有所收获，使学生得到全面的发展，对英语学习充满激情和活力。 2.3教材整合的主要策略 分析教材，找到本套教材的重难点，列出框架体系。教师在拿到教材之后首先应根据课程标准对教材进行分析，找出本学期教学的重难点。如人教版七年级上册英语课本，本册英语教材只涉及浅显的语言知识点，与学生的生活息息相关。因此，教师在教学过程中要重视学生的学习能力和培养学生逻辑思维能力和学习习惯，此外还应根据学生的真实生活进行教学，培养学生对英语的学习兴趣。 适当的补充或延伸。我们处于信息网络时代，要善于运用网络资源，对教材资源进行补充和延伸。例如在必修3 unit1 Festivals in the world ，在本单元导入之前可以在网上查阅世界各地的节日传统，让学生了解更多的西方文化知识，扩大他们的知识层面，达到英语教学的效果。 适当的删减或替换。对于教材中不太适合的内容，在进行教学设计时要依据学生的认知规律，进行替换和删减。如果全部照搬教材，学生会产生畏惧或厌倦的情绪，因此教师在备课时应经过严密思考，在不影响基本教学的情况下，替换和删减不符合学生的生活实际的内容。如在讲授冠词a/an 的用法时，如果只讲授语法必然会很枯燥，因此我们在对教学内容进行整合时，可以对教材
