Lists can be either **arrays**, where elements are stored in contiguous memory locations, or **linked lists**, where each element contains a reference (or link) to the next element in the sequence. Lists are versatile and can be used to **implement various data structures**, including stacks and queues, but unlike these structures, lists do not restrict the insertion and removal of elements to specific locations.
+ - **Queue**: A linear structure following a First In, First Out (**FIFO**) order. Elements are added at one end and removed from the other, like a line of people.
+ - **Heap**: A **tree-based** structure where each node is ordered according to a **comparison** property (e.g., in a max heap, each parent node is greater than its children). Used in priority queues and heap sort.
+ - **Stack**: A linear structure following a Last In, First Out (**LIFO**) order. Elements are added and removed from the same end, like a stack of plates.

+# 动机信 (Motivation Letter)
+
+原文地址:https://fine-seed-211.notion.site/Motivation-Letter-69b629f48b2344c7be7379ed84d403d2?pvs=4
+
+## 0. 引言
+
+本文将讲解留学申请中的动机信,英文 Motivation Letter 或 Letter of Motivation。
+
+本文主要分为五节:
+
+1. 第一节:解释动机信的含义。本节首先会展示三个申请项目对于动机信的要求,随后我将根据我的申请经验来总结动机信的格式和内容。如果你对“动机信”一词毫无了解,那么本节可以帮助你对“动机信”建立一个基础且正确的印象。
+2. 第二节:解释动机信的内容和格式。本节将沿用第一部分的总结,逐段讲述注意事项和撰写思路。
+3. 第三节:本人动机信案例讲解。本节我会使用我的一封动机信成稿作为案例,逐句讲解我的全文构思、撰写思路,以及其中琐碎的的写作技巧;并且我会尽量将这种思路总结为一种较为通用的模板,以便大家参考。
+4. 第四节:多个项目的动机信。申请多个项目时并不需要为每个项目都写一封动机信,而是基于一个通稿,根据项目具体内容修改其中一两段。本节我将使用我的两封动机信,讲解我根据两个项目的差异而对动机信的修改内容和修改思路。
+5. 第五节:该思路的其他应用。虽然本文讲述的是动机信写作思路,但是其适用性远不止“动机信”这一个文书;其他常见文书和奇奇怪怪的文笔材料也可以套用。
+
+本文的特点是:
+
+- 大量使用举例论证,每个例子都来自项目官网且注明出处以验证正确性。
+- 所有写作思路不止于空话套话,而是给出非常具体、能够复现的思路,努力让任何读者走一遍流程后能找到自己的写作内容。
+- 在较为重要的写作节点中设置保底文案,即俗称“万金油”。即使你跟着我的思路走一遍后依然未能自发产出内容,依然能参考该保底文案撰写初稿。
+- 使用我本人的一封动机信成稿作为案例进行讲解,既能佐证思路的可行性,也放出了成稿文本供大家参考。
+- 将我的动机信修改为通用模板,并将可下载文件放置于文末。你可以参考这篇模板撰写初稿,应该会比完全从零开始写简单一些。
+
+注意:
+从我的角度出发,在撰写动机信之前,我浏览了许多动机信写作经验帖、观看了B站诸多讲解视频、还向同校学长要了他们的撰写范本。经过整合信息和深入思考,我形成了现在的写作思路。对我个人而言,我认为我写的动机信比我看过的任何讲解都更出色。
+然而,从你的角度来看,我的写作经验只是你搜罗的众多经验帖中的一个。请不要把本文当作动机信的唯一写作标准,也不要直接照搬本文提供的模板,因为该模板一定也会被其他人参考。建议你再广泛搜索资料后,综合考虑,去选择、去拼接、去创造一种属于你的写作思路。如果经过考量后,你依然认为我的这篇经验帖最佳,那将是我的荣幸。
+
+## 1. 什么是动机信
+
+让我们先来看几个项目给出的动机信内容要求:
+
+1. University of Helsinki, Master’s Programme in Computer Science;
+ 赫尔辛基大学,计算机科学硕士项目。
+
+ URL:https://opintopolku.fi/konfo/en/hakukohde/1.2.246.562.20.00000000000000036106/valintaperuste
+
+
+
+
+

+ >
+
+ 注:此处提及的分值为芬兰留学制度的打分制,与动机信无关,故不详述。
+
+2. Aalto University, Master of Science in Computer Science;
+
+ 阿尔托大学,计算机科学理学硕士项目。
+
+ URL:https://www.aalto.fi/en/study-options/computer-science-computer-communication-and-information-sciences-master-of-science-technology
+
+
+
+
+
+
+ 原文:
+
+ > Based on your application documents (transcript of records, CV, other supporting documents), reflect on your
+ >
+ > - relevant experience and achievements,
+ > - expectations and motivation for MSc studies majoring in Computer Science at Aalto University including which study track of the major you tentatively wish to follow, and
+ > - future career aspirations and how MSc studies in Computer Science contribute to them.
+ >
+ > The motivation letter should be written in English. The recommended length is one page (font size 11 pt).
+ >
+
+ 翻译:
+
+ > 根据您的申请材料(成绩单、简历、其他证明文件),反映您的
+ >
+ > - 相关经历和成就、
+ > - 对在阿尔托大学主修计算机科学理学硕士项目的期望和动机,包括您暂定的主修方向,以及
+ > - 未来的职业抱负,以及计算机科学理学硕士项目如何有助于实现这些抱负。
+ >
+ > 动机信应使用英语书写。建议长度为一页(字体大小为 11 磅)。
+
+3. KTH Royal Institute of Technology, master’s programme in Computer Science;
+
+ 皇家理工学院,计算机科学硕士项目。
+
+ URL:https://www.kth.se/en/studies/master/computer-science/entry-requirements-computer-science-1.419975
+
+
+
+
+
+
+ 原文:
+
+ > The letter of motivation explains why you have chosen this programme at KTH, what you hope to gain from it and how your interests and skills will help you succeed in your studies. Include an autobiography with the development and relevance of your academic and professional pursuits, extra-curricular activities and related experiences. KTH does not require a standard template, but it must be in English and less than 500 words. If you apply to multiple programmes that require a letter of motivation, you should submit one for each and state which programme each letter applies to at the top of the page.
+ >
+
+ 翻译:
+
+ > 在动机信中说明您为什么选择 KTH 的这一项目,您希望从该课程中获得什么,以及您的兴趣和技能将如何帮助您成功完成学业。在动机信中还应包括一份自传,介绍您的学术和专业追求、课外活动及相关经历的发展和相关性。瑞典皇家理工学院不要求标准模板,但它必须为英文,字数不超过500字。如果您申请的多个专业都需要动机信,您应为每个专业提交一封动机信,并在页面顶部注明每封动机信适用于哪个专业。
+ >
+
+从上述三个项目的要求不难看出,虽然各学校项目对于动机信的文本描述有所差别,但是其本质内容几乎相同。
+
+笼统而言,动机信是一封信;内容需要包含以下信息(不分先后顺序):
+
+- 简单的自我介绍
+- 你的相关经历和成就
+- 为什么选择该大学、为什么选择该项目
+- 你的经历和技能如何帮助你在项目中取得成功
+- 期望从项目中获得什么
+- 未来的职业方向、该项目如何帮助你实现该目标
+
+格式方面,几乎所有项目都会说“无固定格式要求”“不需要标准化模板”等,但一般约定俗成以下两条限制:
+
+- 书信格式
+- 包含在一页 A4 纸内
+
+以上我对“动机信”的总结,可以满足绝大部分项目的要求,你可以以此为参照撰写初稿。但各项目难免有所差异,如果项目的动机信要求与上述条目不符,那么这些条目就需要遵从项目的要求,而项目未提及的部分依然可以参考我的总结。
+
+例如荷兰的埃因霍温大学(Eindhoven University of Technology, TU/e)对于动机信的要求中有提到:
+
+- with a maximum of two A4 pages
+- 最多两张 A4 纸
+
+
+
+
+
+ 来源:TU/e申请系统,需要注册登录后才能看到,故无固定URL
+
+
+
+那么在撰写该项目的动机信时,就可以在某些部分酌情多写一点、多提一些项目经历,让动机信内容保持在两页 A4 纸内而不是一页。
+
+## 2. 如何撰写动机信
+
+由于动机信的格式讲解起来较为简单,因此本节先讲解格式,再讲解内容。
+
+### 2.1 动机信格式
+
+#### 2.1.1 书信格式
+
+动机信的书信格式并不需要特别复杂,只需要让审阅者一眼看出即可。我采用的格式如下:
+
+开头:以下二选一
+
+- To whom it may concern,
+- To Admission Office,
+
+结尾:
+
+Yours sincerely,
+Yuhang Lin
+
+
+
+除去动机信内容本身外,部分项目还可能要求你在顶部或底部加一些额外文本,如第一部分提到的 KTH 便要求:
+
+> If you apply to multiple programmes … you should … state which programme each letter applies to at the top of the page.
+>
+
+> 如果你申请多个项目…你应该…在页面顶部注明每封动机信适用于哪个项目。
+>
+
+
+
+3. 就业市场、人生帮助
+
+ 结尾句需要将硕士生涯的计划与职业目标联系起来,说明你这样规划硕士生涯,就是为了实现你的职业目标,也就是高考作文中的“升华主题”。
+
+ 构思此处时需要将视角再提高一层,从整个就业市场甚至是人生的角度去思考,并尽量让“就业市场”“人生”这些宏观表达出现在句子中。例如“能增强我在就业市场中的竞争力”“能让我朝着人生理想更进一步”等等。努力夸大事实、怎么听着厉害怎么来。
+
+
+#### 2.2.5 结尾
+
+纯套话,直接把下面这段拿去用:
+
+Thank you for considering my application. I look forward to the possibility of contributing to and learning from your distinguished program.
+
+## 3. 本人动机信案例讲解
+
+本小节,我将使用我为阿尔托大学的软件与服务工程硕士项目 ([Aalto University, MSc Software and Service Engineering](https://www.aalto.fi/en/study-options/software-and-service-engineering-computer-communication-and-information-sciences-master-of-science)) 撰写的动机信作为案例,逐段讲解写作思路。我会先讲解我在撰写时的心路历程,然后将这封动机信比较通用的文本总结成一个模板,供大家参考。只要你遵循与我相同的步骤,至少能写出一封不差的动机信初稿。
+
+为了更好的传达写作思路,本小节将以图片为载体叙述段落架构和文本,请耐心阅读所有图片内容;一些额外细节和构思依然使用文字表述。
+
+整封动机信中固定文字如下,无论给哪个申请项目写动机信,这些固定文本都不需要变动:
+
+
