Dear Admission Committee:
Miss Pan Bei requested a letter of recommendation from me to support her application for graduate program at your university. As her teacher, I am pleased to comply with her request.
I first got to know Miss Pan when she enrolled at university and I was the assistant director of her class at that time. Being a professor for several years, I noticed that due to the lack of self-learning ability, it is really challenging for students, even those performing excellent in senior school, to keep up with the college speed. However, as a diligent girl without any solid background in Computer Science before college, she adapted quickly to the especially competitive environment in our department. At the end of the first year, she earned the 5th rank in her class, while ranking 1st among the girls. I was fairly impressed by her self-learning technique and exceptional efforts. Hence, I believe, goal-oriented, not afraid of inchoateness and with persistence, she has the quality to make achievements.
What distinguished her among her classmates, I think, was that she went far beyond acquiring excellent scores in the exams and instead got her range of knowledge enlarged. In spring, 2006, Miss Pan took the course I taught named Algebraic Structures and Combinatorial Mathematics. This inquisitive and assiduous young woman was sometimes the last to leave after my class, raising novel questions related to the subject. I found that she understood the knowledge in depth and detail. Furthermore, I still remember during the spring vocation in May, due to the break-down of my mail box, I missed her mails to discussing some questions. But the following week during the course time, she asked me directly. Her zeal for knowledge and the spirit to explore answers really leave me a deep impression. Finally, she was among the few students who got almost full marks in every test in class which showed her exceeding grasp of every chapter. Thus, I gave her 98/100 for the excellent performance in my course.
In summary, I have every reason to believe that Miss. Pan will make outstanding performance at your university as a graduate. I would appreciate greatly if you give her a favorable consideration. Please feel free to contact me directly if more assistance is needed. Faithfully yours,
Wanling Qu, Professor
Department of Computer Science and technology Peking University

今年的四月四日,我们度过了一个特别的清明节。这天,我们为在疫情中牺牲的同胞们默哀,寄予了无限哀思。作为最为人们熟知的中国传统节日之一,清明节究竟有什么来头?
提及清明节的起源,我们就不得不说起,另外两个今日已逐渐为人们淡忘的节日——上巳节与寒食节。在宋朝之前,这三个同位于三月上旬的节日,是同时存在的。
上巳节一般在农历三月初三,相传是为纪念黄帝诞辰而设置,是中华最古老的节日之一。这一天人们通常会招魂辟邪,因传说柳条可以招魂辟邪,故在上巳节这天,人们会编柳条,折柳枝并随身携带。此外,上巳节能进行的传统活动,还有许许多多,例如在巫师道士的指导下,进行一项称作“祓禊”的活动。甚至,据说就连汉武帝都在上巳节当天求过子。正因习俗活动众多,官方钦定的上巳节,受到了众多百姓的喜爱。
而寒食节的起源,则伴随着一个传说。传说春秋时期,因晋国内乱,公子重耳,即后来的晋文公,流亡乡野。与其同行者中,有一个人名叫介子推。一天,重耳病倒,但因钱财几乎用尽,没有食物可以供其养病,无奈之下,介子推一咬牙,割下了自己大腿上一块肉,熬了一锅肉汤,献给重耳。重耳后来知道真相后,感动非常。后来重耳成功即位,称晋文公,他赏赐了几乎所有流亡时期的随行者,却偏偏忘记了介子推。后经人进谏后,晋文公忙去寻找介子推,然而介子推已带着老母亲隐居山中,不愿出山了。《异苑》中这样记载:“介子推不出,晋文公焚林求之,终抱木而死。公抚木哀嗟,伐树制屐,每怀割股之恩……视屐曰:‘悲乎足下!’”晋文公放山火逼介子推出山,却不幸烧死了介子推。晋文公后悔非常,为纪念介子推,他下令,一段时间内,所有人不准用火,只可食冷饭,故称“寒食节”。寒食节这天,人们通常扫墓上坟。
最初的“清明”,其实并非一个节日,而是一个节气,出现在冬至后一百零八天。清明能成为一个节日,其原因有很大一部分是其紧随在距冬至一百零五天的寒食节之后。在寒食节,人们进行了严肃的祭祖活动,恰好清明就为人们提供了出门踏青郊游的欢乐时光。
不过,虽然清明成了一个节日,但人们仍然偏爱活动丰富的上巳节。直到一个富足且百姓生活安定幸福的朝代——唐代诞生了。
在唐朝,清明这天踏青郊游,成了几乎为所有百姓所热爱的一项习俗。而且不但人们在这天加入了大量娱乐活动,朝廷还确立了一个为期七天的“小长假”,这让清明节为百姓着喜爱的程度,甚至一举赶上上巳节。
到了宋代,人们推崇“理学”,也就是“存天理,灭人欲”,朱熹就是一位著名的理学家。理学家们认为,上巳节的一些习俗是“伤风败俗”的,于是上巳节便渐渐没落。取而代之的,是寒食与清明的组合,这时的清明,还没有现在扫墓等习俗。
后来,因寒食节只有单一沉闷的祭祖功能,清明脱离了寒食,成为了一个娱乐性节日,在宋代成为了最受欢迎的节日。
到了明清时期,上巳节与寒食节基本消失,于是清明节融其自身的踏青,寒食节的扫墓,上巳节的插柳于一身,成为了现在,我们所熟知的清明节的雏形。
而到了今天,清明节更演变出了新的民族色彩——缅怀先烈,纪念英雄。这是我们,对先辈们流传下来的传统节日的一次传承与升华。四月四日的默哀便是一个极佳的例子。它证明了中华民族的凝聚力,见证了华夏人民对历史精粹的发扬,更标志着国人将一个个人的节日,上升到了民族集体的层面。这可以作为我们传承东方古典文化的一个楷模。
清明节这样的传统节日们,每一个都蕴藏着深厚的文化与时间的积淀。迈入二十一世纪二十年代的我们,不仅要传承祖辈们的优良文化,更要对其加以顺应时势的改良优化,让古老的中华文明继续保持着蓬勃的生命力!
在二十四个节气中,既是节气又是节日的只有清明(冬至在历史上也是一个节日,但现在各地大多不再过此节)。清明节的名称与此时天气物侯的特点有关。西汉时期的《淮南子·天文训》中说:“春分后十五日,斗指乙,则清明风至。”“清明风”即清爽明净之风。《岁时百问》则说“万物生长此时,皆清洁而明净。故谓之清明。”虽然作为节日的清明在唐朝才形成,但作为时序标志的清明节气早已被古人所认识,汉代已有了明确的记载。
二十四节气是中国古代天文学家和民众在生活和生产实践中总结出来的气候规律,比较适宜地反映了一年四季气温、物候、降雨等方面的变化,对人们依时安排农耕、蚕桑等活动有不可或缺的指导意义。到了清明,气温变暖,降雨增多,正是春耕春种的大好时节。所以清明对于古代农业生产而言是一个重要的节气。农谚说“清明前后,点瓜种豆”、“植树造林,莫过清明”,正是说的这个道理。东汉崔寔《四民月令》记载:“清明节,命蚕妾,治蚕室······”说的是这时开始准备养蚕。其中的“清明节”还只是一个节气,不是节日。
此外,清明时处早春三月,春光明媚,万物复苏,气候宜人而到处生机勃勃,是春游和郊外娱乐的好时光,所以清明前后自然成为人们乐于到户外、郊野嬉游的的好时光。
清明节主要指节日而不是节气,但是清明节气在时间和天气物侯特点上为清明节俗的形成提供了重要条件,该节气应看作清明节的源流之一。
Dear Sir/Madam:
As a teacher at xxxx school, I am writing to provide you a recommendation for Miss/Mr.xx so as to help you assess her/his application for acceptance into your program and consideration for financial aid.
Considered a promising student with originality and sophistication in her/his thinking, (she/he was asked, in the spring semester of 2008, to develop a subsystem of a DBMS project for her B.S.thesis, for which I was the chief leader. T
his subsystem was designed to manage the information of materials in NO.1 Foundry Plant of Dongfeng Auto Works.To do the job, she/he read many books about software engineering and took some courses in Database Principles and Management. Keenly aware that the design of a DBMS decides the quality of the whole software system, she did her/his utmost from the beginning of the project.(参加过什么活动. From analyzing users requirements to designing the whole system, from the detailed designing to the final programming, she was very level-headed and full of innovation every step of the way. Taking full advantage of her ability and creativity, she firmly focused herself on her objective and gnored all distractions. She successfully reached her goal. In the final software testing, only a few bugs were found in her subsystem. My appreciation of her talelent was thus confirmed.Miss is a very personable woman, friendly and helpful, and she has always been a team player in her work.
