We don’t know if either story is true, but they are both interesting.The first explanation is based on the fact that President Jackson had very little education. In fact, he had difficulty reading and writing. When important papers came to Jackson, he tried to read them and then had his assistants explain what they said. If he approved of a paper, he would write “all correct” on it. The problem was that he didn’t know how to spell, so what he really wrote was “ol korekt”. After a while, he shortened that term to “OK”.The second explanation is based on the place where President Van Buren was born, Kinderhook, New Y ork. V an Buren’s friends organized a club to help him become President. They called the club the Old Kinderhook Club, and anyone who supported V an Buren wa s called “OK”.11. The author ____C______.A. believes both of the storiesB. doesn’t believe a word of the storiesC. is not sure whether the stories are trueD.is telling the stories just for fun12. According to the passage, President Jackson ______D____.A. couldn’t draw up any documents at allB. didn’t like to read important papers by himselfC. often had his assistants sign documents for himD. wasn’t good at reading, writing or spelling13. According to the first story, the term “OK” ______C_____.A. was approved of by President JacksonB. was the title of some official documentsC. was first used by President JacksonD. was an old way to spell “all correct”14. According to the second story, the term “OK” _____D_____.A. was the short way to say “Old Kinderhook Club”B. meant the place where President V an Buren was bornC. was the name of V an Buren’s clubD. was used to call V an Bur en’s supporters in the election15. According to the second story, the term “OK” was first used _____B____.A.by V an BurenB.in a presidential electionC.to organize the Old Kinderhook ClubD.by the members of the “Old Kinderhook Club”Passage TwoNormally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice.For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes（施加）a constant（持续不断的）pressure and strain （负担）of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The student organizations are effective in ensuring that the students observe university regulations. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.16. Normally an American university student would attend ___A_____ courses for a degree.A.36B.20C.12D.1517. According to the first paragraph an American student is allowed _____B____.A.to live in a different universityB.to take a particular course in a different universityC.to live at home and drive to classesD.to get two degrees from two different universities18. American university students are usually under pressure of work because ___A______.A. their academic performance will affect their future careerB. they are heavily involved in student affairsC. they have to observe university disciplineD. they want to run for positions of authority19. Some students are enthusiastic for positions in student organizations probably because ____C____.A. they hate the constant pressure and strain of their studyB. they will then be able to stay longer in the universityC. such positions may help them get better jobsD. such positions are usually well paid20. The student organizations seem to be effective in _____B____.A. dealing with the academic affairs of the universityB. ensuring that the students observe university regulationsC. evaluating students’ performanc e by bringing them before a courtD. keeping up the students’ e nthusiasm for social activities三．词汇语法（每小题2.5分，满25分）21.

《运筹学》学习方法一、课程性质和任务《运筹学》课程是网络教育考试的一门必修课。

这门课程的主要特点是数量分析与计算机操作。

设立本门课程的目的：通过本课程的学习使学员充分认识到运筹就在自己身边，它是经营管理和决策过程中不可缺少的组成部分，是经济管理中定量分析的基础，对合理管理和正确决策起着相当重要的作用。

同时，能应用运筹学的理论与方法解决经济管理中的实践，并辅助决策。

二、课程学习的基本要求运筹学是一门实践性很强的学科，因此，运筹学的学习主要通过实践练习来逐步提高对基本理论的掌握，因此在学习了基本理论后，一定要拿起笔做些自我练习。

由于网络教育这种新的学习形式下，实现面对面的交流是不可能的，所以大家在有问题时要多多到论坛上说出来，以便大家共同讨论、共同进步。

下面提出几点建议：1、网络教育的优势在于省时、省力，便于大家灵活安排学习计划。

劣势是不便与老师、同学直接交流。

所以，参加网络学习的同学要有一定的自学能力，主要是通过制订计划，按步骤完成计划来提高知识水平。

2、制定学习时间表并坚持执行，每天坚持拿出一定时间来上网学习，对于网络教学来说，如果上网时间都不能满足，是很难达到教学效果的。

3、增加网上的交流，这包括和老师、同学的交流，网上的资源是丰富的，所以我们应充分利用这一优势，使我们在有限的时间内学到更多的知识。

4、在学习基本理论后，尽力找些容易做的题目，亲自操作一下，这便于掌握刚刚学到的方法。

5、考前串讲对考试是十分主要的噢，一定要参加并认真听。

平时的作业也要认真完成，这样你才有可能拿到好成绩。

希望大家多多沟通联系，以弥补网络教育的不足。

希望与大家成为好同学、好朋友。

三、课程内容和掌握程度《运筹学》主要围绕运筹学建模思想主题，逐步讲述各种建模思想以及相关常用方法。

这门课程的内容大体可分为六个部分。

第一章绪论第一节运筹学简史一、运筹学的产生二、运筹学发展三、运筹学经典案例第二节运筹学的概念和特征一、运筹学的概念二、运筹学的基本原则三、运筹学的特征第三节运筹学的工作步骤第四节运筹学的应用第五节运筹学的展望三、实践（上机）环节内容和基本要求（有实验或上机内容的才写）自学安排：对应各知识点内容与上机要求结合教材预习和复习第二章运筹学模型一、学习要求通过本章的学习，要求学生能根据实际问题建立运筹学模型。
