2009年专升本(大学语文)真题试卷(题后含答案及解析)题型有:1. 选择题 5. 古文阅读6. 现代文阅读7. 作文选择题在每小题给出的4个选项中,只有一项是符合要求的。

1.茅盾《香市》一文采用的主要写作手法是A.夹叙夹议B.情景交融C.寓情于景D.今昔对比正确答案:D解析:茅盾《香市》一文共分两部分,分别写“香市”的昔盛今衰的场面和气氛。

昔日的“香市”是农民为祈神赐福、借佛游春而自发组织的,农民和儿童是这狂欢节的主角。

昔日民间的“香市”到处洋溢着欢快的节日气氛。

而“革命”后,重兴“香市”是由小商人发起的,呈现出萧条、冷清的景象。

这是本文总体上的对比,是《香市》一文主要的写作手法。

文章通过“香市”昔盛今衰的现象,反映了20世纪30年代中国江南农村、市镇面貌的变化,揭示了大革命以后帝国主义经济侵略、军阀反动势力深入农村和小商人转嫁危机所造成的中国农村自然经济日益凋敝的现实,展示了旧中国由封建自然经济向半封建半殖民地经济的转变,并没有给农村经济带来发展,反而加剧了农民的贫困和破产这一悲剧。

因此正确选项为D项。

除了今昔对比之外,文章中还有场面对比、气氛对比、节日内容的对比等各方面的层层对比,建议考生在复习时全面掌握。

[错误防范] 文章在写作上还将“理”与“情”、“议论”与“具象”互相融合,使作品形式精巧简练,立意深刻、蕴藉丰富。

因此前三项选项也比较切合《香市》的写作手法,但是注意,这些都是次要的写作手法,并不是主要写作手法。

因此此题的关键在于熟悉文章,总览全文,宏观把握,避免误选其他选项。

2.契诃夫《苦恼》中老车夫姚纳的苦恼是A.风雪交加中拉不到乘客B.小马没有食物C.儿子突然病故D.无处诉说丧子之痛正确答案:D解析:《苦恼》是一篇反映劳动人民内心痛苦的抒情心理小说。

小说描写了一个鳏居多年,又刚刚失去爱子的马车夫姚纳,想找人诉说一下丧子的悲痛,但却屡次遭到周围人的冷眼、蔑视和辱骂,后因找不到倾诉的对象,只得向自己的老马诉说内心的哀痛与苦恼,揭示了社会底层“小人物”的贫穷和得不到关心又无处诉说的悲惨处境。

硬件系统是计算机系统的实体,主要由五大部分组成:运算器、控制器、存储器、输入设备和输出设备。

软件系统主要是指让计算机完成各种任务所需的程序,包括系统软件和应用软件两大类。

2.参考答案:任务是在软件投入生产性运行之前,尽可能多地发现软件中的错误。

与测试的区别:测试是为了发现软件中的错误,而调试是诊断并改正错误。

3.参考答案:RAM是随机存储器。

断电后的内容全部丢失,既可以读又可以写,速度比Cache 慢,可分为静态RAM(SRAM)和动态RAM(DRAM)两种。

ROM是只读存储器。

计算机运行时其内容只能读出而不能写入。

数据不易丢失,即使计算机断电后ROM存储单元的内容依然保存。

只读存储器一般存储计算机系统中固定的程序和数据,如引导程序、监控程序等。

4.参考答案:按计算机机型分,可分为微型计算机操作系统、小型计算机操作系统和大型计算机操作系统;按用户数目,可分为单用户操作系统和多用户操作系统;按处理方式,可分为批处理系统、分时操作系统、实时操作系统、网络操作系统和多媒体操作系统;按处理语言,可分为英文操作系统、中文操作系统、日文操作系统等;按用户操作界面,可分为字符型操作系统和图形操作系统。

Do not allow yourself to become distracted by non-vital activities. Always bear in mind the emergency action—Assess, Make Safe, Give Emergency Aid, and Get Help.Your approach should be brisk(快的), but calm and controlled, so that you can quickly take in as much information as possible. Your priorities are to identify any risks to yourself, to the casualties(伤亡人员), and to any other people around, then to access the resources available to you and the kind of help you may need.State that you have first-aid skills when offering your help. If there are no doctors, nurses, or more experienced people present, calmly take charge. First ask yourself these questions: Is there any continuing danger? Is anyone's life in immediate danger? Are there any other people who can help? Do I need specialist help?The conditions that caused the accident may still present further danger. Remember that you must put your own safety first. You can't help others ifyou become a casualty yourself.Often, very simple measures, such as turning off an electric switch, are enough to make the area safe. Sometimes more complicated procedures are required. Never put yourself and the casualties at further risk by attempting to do too much; be aware of your limitationsIn order to act effectively during an emergency, you are advised to _____()A.ask for help from a hospitalB.seek an expert's adviceC.turn to the police for helpD.follow a clear plan46.47.____47.Which of the following is NOT mentioned as a sign that your job is doing harm to your health()A.Aches or pains for reasons unknownck of interest in activitiesC.Failing rememberingD.Eating too much48.Which of the following statements is NOT true()A.Children’s resistance to illness is directly proportional to their poor nutritional statusB.The well-nourished tend to recover quickly when they are illC.The poorly-nourished are most likely to be the victims of infections and diseasesD.The cycle indicates that illness can turn the poor nutritional condition for the worse49.The best title of this passage can be_______()A.Effect of EducationB.Dependence on EnvironmentC.IntelligenceD.Surroundings50.44.____()51.Which of the following is the author's suggestion()A.Open the gift immediately in front of the giverB.Wrap the gift carefullyC.Express the appreciation for the gift you receiveD.Buying a present card to avoid the trouble in shopping52.What can we learn about the Health and Retirement Study()A.It has been carried out by the National Institute on Aging for about 20 yearsB.The study surveys the Americans of all agesC.The two economists have done enough research in this fieldD.The two economists administer memory tests to many old people every two years53.What is Career Consulting()A.It is a company offering jobs for peopleB.It is a movie played by Charles ChaplinC.It is a plant making hunting toolsD.It is a business company helping people find jobs六、作文题(1题)54.Directions: For this part, you are supposed to write a composition on the topic: Hazards of High Altitude Throwing.
