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

以“惊、险、奇”著称于世的司马台长城，位于密云县古北口镇境内，距北京市区120公里，是我国惟一保留明代原貌的古建筑遗址。它南靠白龙潭风景区，西邻金山岭长城，东靠云岫谷游猎区，是集旅游观光、科教、探险、温泉疗养、休闲度假为一体的旅游佳地。
司马台长城全长19公里，敌楼35座，始建于明洪武初年。司马台长城惊险奇特，横卧于山峰之巅，并在陡峭的山峰间架起一座天梯，倾斜度达85°，有百米之长，天梯两侧皆为深渊，而天梯的石阶窄小，仅为一砖之宽，任何人想轻松地通过这里都将不会是一件容易的事。整段长城构思精巧，结构新颖，形态各异，集万里长城所有特点于一处，形成了一段“奇妙的长城”。望京楼是司马台长城中的最高点。著名长城专家罗哲文教授指出，“长城是中国建筑之最，而司马台长城是中国长城之最”。
这里东观“雾灵积雪”，西望“蟠龙卧虎”，北看“燕山叠翠”，南瞧“水库明珠”，大好河山尽收眼底。位于陡峭如削的危崖之上，有一道通天的石梯，只容一人攀登。
司马台长城还建造了登城隐形索道、游览峡谷索桥等设施，并有一年一度的司马台长城登山赛和司马台国际滑翔节、文化节。在这里，您可以鸳鸯湖上泛舟、游泳、垂钓，还可以山寨野味烧烤等。
天梯高耸入云端，天桥悬挂云海间。
婷婷玉立仙女楼，不登望京真遗憾。

万里长城是世界古代建筑的奇迹。早在春秋时期，楚国就修筑了长数百千米的非封闭性城墙，叫作方城。战国时，燕、赵、魏、韩、秦等都在边界筑起了长城。秦始皇统一天下后，把燕、赵、秦原有的北方长城连接起来，筑成西起临洮东至辽东的长城，长万余里。今山西大同北部，甘肃岷县城西等地均有秦长城遗址。
西汉沿河西走廊一带向西增筑朔方长城和河西长城，经玉门关延伸到今新疆境内，以保护河西走廊。北魏时西部柔然人满为患，又兴筑长城以防柔然人南侵。北齐也多次修筑长城。隋代为防御突厥、吐谷浑，数度修筑长城。明朝建立后，大将徐达曾18次在居庸关修筑长城。明长城西起甘肃嘉峪关，东至鸭绿江，这就是今天我们见到的万里长城。
明长城主体是城墙。山西东面至山海关一段，断面下宽上狭，平均底宽6米，高逾6.5米，外砌整齐条石和特大城砖，内部夯土。城墙顶部用三、四层砖铺砌，最上一层是方砖，用石灰勾缝，十分平正坚实，连野草也难以生根，平均宽5米，可容5马
并骑10人并进。墙顶两侧还砌有砖墙，内侧砌成约高1.5米的矮墙，外侧砌成约高1.5米的垛墙，每一垛牙上面有了望孔，下面有一射击眼。城墙上有排水沟、吐水嘴等设施，在关口和险要的地方还设有凸出的罗城。
修筑长城的工程浩大，筑长城所用土方如所来筑一道厚1米、高5米的墙，可绕地球一周有余。筑长城一般就地取材，大型城砖和石灰是就地烧制的。在高山峻岭，则开采石料，用石砌筑。在沙漠中，用红柳枝条和芦苇与砂石层层相间铺砌，可砌到6.5米以上。在黄土地区，大都取土垒筑，在重要地段的城墙一般用砖砌和条石镶砌
