这便是期末
——记2018年初期末备考这便是期末了。
期末的氛围来得早，12月过半就有了，从那时起大家开始慌里慌张地做事，匆匆忙忙地赶作业，各式的社团活动与工作也大都进入了尾声，老师们在讲课时会赶进度，课本一页一页刷刷地翻，爱学习的与不爱学习的同学们都被带入了一种紧张的氛围，寒冷变得粘稠。
在这个阶段我们还可以紧张兮兮地玩手机，也时不时约个饭，唱歌，通宵，都是有的，在一个学期的末尾、考试来临之前，算作最后的狂欢。我不知道大家是否尽兴，或者也是姑且开心，竭力的快活虚幻而荡漾，像是无味的烈酒，容易上头，令人晕眩，而醒来又落在熟悉的时光里，平淡，被迫充实。
正儿八经旳期末于我而言是在考试前一两周正式降临了的，以泡图书馆作为标志。为何要泡图书馆？大抵是因为过去一段时间的实践再次证明了宿舍不是复习的好场所，课也一门一门结了，终日里没了一定得做的事，那便去泡图书馆，大家都说，在图书馆学习效率更高，都期末了，你为什么还不去图书馆？
期末的我浸泡在图书馆里，华师的期末也浸泡在图书馆里。我时常想，华师的图书馆似乎只在每年的几个特定时段日日宾客盈门，比如说考前的一周，若是上午八点钟赶不到，便坐不了好的位置，而若是九点钟赶不到，不那么好的位置便也就没有了。什么是好的位置？靠窗，偏僻，有插座为佳。于是要想好好复习，日日得按上早课的时间起床，紧赶慢赶着，在图书馆门口前和来自校园各处的同侪们汇成一股涓涓的人流，然后一齐涌进去，各自落座。
图书馆待我们显然很是不错，它并不分辨谁是熟人，谁是稀客。空调，热水，明亮的光线和即便人多也依然宁静的氛围，这是期末的背景音，也是期末备考的主战场。我想大概会有至少一半的华师学子，在这里写字，背书，半真半假地调侃自己正式开始预习。
图书馆没有上课铃，也没有课间，度量时间的单位从“节”变成了“晌”，在这样长的时间里，不是所有人都是可以埋头苦读奋笔疾书的，尤其是图书馆的稀客们，而我恰巧算得上是稀客之一，不过好在四处都是可以将意识短暂流放的去所。
我在复习的间隙里抬起头喝水，打量视线所及的人群，都是陌生的，也都是熟悉的，不一样的面孔，却都是二十岁左右的脸庞。我看到有人交谈和嬉戏，也看到有人备了咖啡和水果，听到过呼噜，看到过游戏；看到有的位置被放了书，然后终日空着，不知那未曾谋面的主人长相如何。我在复习的间隙里逃到书架中间，这里可以暂时地不见人烟，满满都是有趣的无趣的书籍，可以随手挑选，随处阅读。书架排列地整齐，从一侧看，是非常规整的几何形状，我想，很适合拍照。
期末在图书馆里进入高潮。准备考试是一种氛围，开始考试好像是另一种，尤其是在考试进入最后一周时。这时的我们心情更加激动，却也更加疲惫，战线被拉地如此漫长，我们在一门一门考试科目之间切换，各科的书本和打印纸摊满了桌子，图书馆的楼梯间也都坐了背书的人。像中长跑进入了结尾，宿舍食堂图书馆，看书背书做习题，这是令我们不适的状态，也是我们并不熟悉的，我们好像被自己的努力感动，在心底里期待着几日后的狂欢。我也再没有心情在书架间闲逛，只偶尔抬起头看窗外，白天终日阴沉，夜晚各类的灯光在不远处闪烁。
这个阶段的期末是紧绷的，却也短暂。学生证碳素笔文件袋，一个个考场轮流坐过一遍，期末便戛然而止。图书馆来来往往的人消失了。
这便是期末。
前几日落的雪还未化。

大学语文期末考试题2007 一、请翻译下列古文，两题任选一。（10分） 1、智术之士，必远见而明察，不明察，不能烛私；能法之士，必强毅而劲直，不劲直，不能矫奸。人臣循令而从事，案法而治官，非谓重人也。重人也者，无令而擅为，亏法以利私，耗国以便家，力能得其君，此所为重人也。智术之士明察，听用，且烛重人之阴情；能法之直到劲直，听用，矫重人之奸行。故智术能法之士用，则贵重之臣必在绳之外矣。是智法之士与当涂之人，不可两存之仇也。 2、魏其侯窦婴者，孝文（汉文帝）后从兄子也。孝文时，婴为吴相，病免。孝景（汉景帝）初即位，为詹事。梁孝王者，孝景弟也，其母窦太后爱之。梁孝王朝，因昆弟燕饮。是时上未立太子，酒酣，从容言曰：“千秋之後传梁王。”太后欢。窦婴引卮酒进上，曰：“天下者，高祖天下，父子相传，此汉之约也，上何以得擅传梁王！”太后由此憎窦婴。窦婴亦薄其官，因病免。太后除窦婴门籍，不得入朝请。 孝景三年，吴楚反，上察宗室诸窦，毋如窦婴贤，乃召婴。婴入见，固辞谢病不足任。太后亦惭。於是上曰：“天下方有急，王孙宁可以让邪？”乃拜婴为大将军，赐金千斤。婴乃言袁盎、栾布诸名将贤士在家者进之。

Reading Comprehension (2’X20=40’) Directions: Read the following three passages carefully and do the multiple-choice questions. Passage One Dogs are social animals and without proper training, they will behave like wild animals. They spoil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong things. The key to preventing or treating behavior problem is learning to teach the dog to redirect its normal behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit”, it is showing obedience and respect for you. It is necessary to establish yourself as top dog or leader of the dog pack by using extreme measures. You can teach your dog its subordinate role by teaching it to show submission to you. Most dogs love performing tricks for you pleasantly if they accept that you are in charge. Tainting should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and more safely allowed a greater amount of freedom than an untrained animal. 1. Behavior problems of dogs are believed to _______. A) worsen in modern society B) be just part of their nature C) occur when they go wild D) present at threat to the community 2. The primary purpose of obedience training is to ________. A) enable the dog to regain its normal behavior B) teach the dog to perform clever tricks C) make the dog aware of its owner’s authority D) provide the dog with outlets for its wild behavior 3. Effective communication between a dog and its owner is _______. A) an extreme measure in obedience training B) a good way to teach the dog new tricks C) the foundation for dogs to perform tasks D) essential to solve the dog’s behavior problems 4. Why do pet dogs love performing tricks for their masters? A) To show their willingness to obey. B) To show their affection for their masters. C) To avoid being punished. D) To win leadership of the dog pack. 5. When a dog has received effective obedience training, its owner________. A) will enjoy a better family life. B) can give the dog more freedom C) can give the dog more rewards D) will have more confidence in himself Passage Two: Once upon a time there was a wise man that used to go to the ocean to do his writing. He had a habit of walking on the beach before he began his work. One day he was walking along the shore. As he looked down the beach, he saw a human figure moving like a dancer. He smiled to himself at the thought of someone who would dance on the beach. So he began to walk faster to catch up. As he got closer, he saw that it was a young man and the young man wasn't dancing, but instead he was reaching down to the shore, picking up something and

Is It Better to Buy or Rent? The price of housing has kept increasing in recent years, which causes a big headache for people living in cities. A lot of people cannot afford to own a real estate property, so they choose to rent instead of buying an apartment. This group of people does not want to bear burden of mortgage so that they opt for a practical solution. Renting an apartment makes them have a place to stay and thus they can focus on work as well as personal life. Some other people, however, believe that an apartment owned by themselves makes them feel safe and relieved, so they are willing to sacrifice some other aspects of life to borrow money from the bank to buy an apartment. As far as I am concerned, to buy or to rent is all about it will be better to rent first and wait for the good timing when the price is going down to buy. Topic 2: On Job Hopping It seems that nowadays, very few young people are willing to stay in a job position for long, let alone for the whole life. They change jobs constantly. This results from several factors. Firstly, young people like fresh things, and it is easy for them to be fed up with old routine work. So when they stay in a position for a while,the excitement will fade out. They are quite realistic and not willing to waste time in a job they are not interested in. Thirdly, some young people are not satisfied with current salary, believing they deserve better pay. In my opinion, constant job hopping will not benefit young people in their career development. Every job has its own merits and young people can certainly learn something from it as long as they are patient and wise enough. Every job experience is valuable down the career path and young people shall be able to make the most of it. Topic 3: Online Social Network Modern people will be no stranger to online social network. Facebook, Renren and Kaixin001 are probably the most populous networks among Chinese netizen. In these networks, people interact with each other, be it a stranger or a friend, and have a lot of fun in the virtual world. This phenomenon could be a result of the fast development of the Internet and people's great interest of the virtual world. I think it is a very good new platform for people to keep in touch. But it should not be overused. Firstly, some people are addicted to it, which makes them want to get online 24 hours a day. When people spend too much time on one thing,they will naturally have not enough time for study and for work. Secondly, online social network change people's behavior of interacting with others. In virtual world, you just click the mouse and type in words instead of having a face-to-face talk. This will not benefit people's long term friendship, and even harm their interpersonal relationships in real world.
