請假條(written request for leave)是常用應用文之一，用于向老師或上級領導等因身體狀況不好或因某事請求準假的場合。它包括請病假(note for sick leave)和請事假(leave of absence)。

稱呼是dear miss lu，寫在左上角。請假條因是向老師或上級請示，一般以dear...,或my dear...,開頭。有時可在dear之后，用上mr.或miss等的稱呼加上姓氏。有一點要注意，各種稱呼后面一般都用逗號。

署名為wang lei。署名寫在右下角，署名上面一行可以寫上yours, your student等字樣。

英文請假條格式

請假條(written request for leave)是英語學習者必須掌握的常用應用文之一，它包括請病假(note for sick leave)和請事假(leave of absence)。請假條是用于向老師或上級領導等因身體狀況不好或因某事請求準假的場合。

英文請假條寫作需注意三點：

1.英文中請假條的寫法和漢語請假條相同，它一般由四部分組成，即時間、稱呼、正文和簽名。

2.一般而言，可認定請假條是一種簡單的書信文體。請假條一般寫在紙上，不用信封。其書寫格式與書信有很多相似之處，是書信的大大簡化。

3.請假條的特點是要求開門見山、內容簡短、用詞通俗易懂。

【范文例析】

假如你是王立。昨天你和同學們去農場幫助農民們摘蘋果，不幸(unluckily)從梯子上摔下來傷了腿，但傷得不重。醫生讓你在家里好好休息。因此，你向高老師請假兩天(ask for leave for two days)。(2002新疆烏魯木齊中考題)【參考范文】

Sep.28 Dear Miss Gao, I''''m sorry I can''''t go to school today.I helped the farmers pick apples with my classmates on the farm yesterday.Unluckily, I fell off the ladder and hurt my leg, but I wasn''''t badly hurt.The doctor asked me to stay in bed and have a good rest.So I ask for leave for two days.Wang Li 【點評】這是一份采用書信格式寫的請假條。日期是September 28, 日期寫在正文的右上角。由于請假條的內容大多是當天、近幾日因病或因事請假，所以不必寫上年份；稱呼是Dear Miss Gao，稱呼寫在左上角。請假條因是向上級請示，一般以Dear...,或My dear...,開頭。有時可在Dear之后，用上Mr.或Miss等的稱呼加上姓氏。不過，有一點仍要提醒大家，各種稱呼后面一般都用逗號。正文談了一件事：I fell off the ladder and hurt my leg, but I wasn''''t badly hurt.I can''''t come to school.I ask for leave for two days.簡潔明了，用詞口語化。寫請假條只要把請假的理由和請假時間說清楚即可。有的請假條為了說明其請假事由是真實的，在正文之后另起一行，寫上I enclose a doctor''''s certificate.(我附上了醫生證明。)；簽名為Wang Li。簽名(署名)寫在右下角，簽名(署名)上面一行可以寫上Yours, Your student等字樣，有時由于寫條的人和收條的人彼此一般很熟悉，所以在稱呼和簽名上比較隨便和簡單。特別是在簽名部分，有時可簡單到只寫個姓或只寫個名就可以了。

第四篇：BS100字英文介紹

B/S模式

一、介紹

B/S模式是一種以Web技術為基礎的新型的管理信息系統（簡稱MIS）系統平臺模式。把傳統C/S模式中的服務器部分分解為一個數據服務器與一個或多個應用服務器(Web服務器)，從而構成一個三層結構的客戶服務器體系。

第一層客戶機，它是用戶與整個系統的接口?？蛻舻膽贸绦蚓喌揭粋€通用的瀏覽器軟件，如Netscape Navigator，微軟公司的IE等。瀏覽器將HTML代碼轉化成圖文并茂的網頁。網頁還具備一定的交互功能，允許用戶在網頁提供的申請表上輸入信息提交給后臺，并提出處理請求。這個后臺就是第二層的Web服務器。

第二層Web服務器將啟動相應的進程來響應這一請求，并動態生成一串HTML代碼，其中嵌入處理的結果，返回給客戶機的瀏覽器。如果客戶機提交的請求包括數據的存取，Web服務器還需與數據庫服務器協同完成這一處理工作。第三層數據庫服務器的任務類似于C/S模式，負責協調不同的Web服務器發出的SQ請求，管理數據庫。

二、B/S和C/S的區別

1．硬件環境不同：

C/S 一般建立在專用的網絡上，小范圍里的網絡環境，局域網之間再通過專門服務器提供連接和數據交換服務。

B/S 建立在廣域網之上的，不必是專門的網絡硬件環境，例如電話上網，租用設備.信息自己管理.有比C/S更強的適應范圍，一般只要有操作系統和瀏覽器就行。

2．對安全要求不同

C/S 一般面向相對固定的用戶群，對信息安全的控制能力很強。一般高度機密的信息系統采用C/S 結構適宜?？梢酝ㄟ^B/S發布部分可公開信息。

B/S 建立在廣域網之上，對安全的控制能力相對弱，可能面向不可知的用戶。

3．對程序架構不同

C/S 程序可以更加注重流程，可以對權限多層次校驗，對系統運行速度可以較少考慮。

B/S 對安全以及訪問速度的多重的考慮，建立在需要更加優化的基礎之上.比C/S有更高的要求 B/S結構的程序架構是發展的趨勢，從MS的.Net系列的BizTalk 2000 Exchange 2000等，全面支持網絡的構件搭建的系統。SUN 和IBM推JavaBean 構件技術等，使 B/S更加成熟.。

4．軟件重用不同

C/S 程序可以不可避免的整體性考慮，構件的重用性不如在B/S要求下的構件的重用性好。

B/S 對的多重結構，要求構件相對獨立的功能.能夠相對較好的重用.就如買來的餐桌可以再利用，而不是做在墻上的石頭桌子

5．系統維護不同

C/S 程序由于整體性，必須整體考察，處理出現的問題以及系統升級.升級難.可能是再做一個全新的系統

B/S 構件組成，方面構件個別的更換，實現系統的無縫升級.系統維護開銷減到最小.用戶從網上自己下載安裝就可以實現升級。

6．處理問題不同

C/S 程序可以處理用戶面固定，并且在相同區域，安全要求高，需求與操作系統相關.應該都是相同的系統。

B/S 建立在廣域網上，面向不同的用戶群，分散地域，這是C/S無法作到的。與操作系統平臺關系最小。

7．用戶接口不同

C/S 多是建立的Window平臺上，表現方法有限，對程序員普遍要求較高。B/S 建立在瀏覽器上，有更加豐富和生動的表現方式與用戶交流.并且大部分難度減低，減低開發成本。

8．信息流不同

C/S 程序一般是典型的中央集權的機械式處理，交互性相對低。

B/S 信息流向可變化，B-B B-C B-G等信息、流向的變化，更像交易中心。

三、B/S的優點

1、系統開發、維護、升級方便

每當服務器應用程序升級時，只要在服務器上升級服務應用程序即可，用戶計算機上的瀏覽器軟件不需要修改，系統開發和升級維護方便.2、B/S模式具有很強的開放性

在B/S模式下，用戶通過通用的瀏覽器進行訪問，系統開放性好。

3、B/S模式的結構易于擴展

由于Web的平臺無關性，B/S模式的結構可以任意擴展，可以從包含一臺服務器和幾個用戶的小型系統擴展成為擁有成千上萬個用戶的大型系統.。

4、用戶使用方便

B/S模式的應用軟件都是基于Web瀏覽器的，而Web瀏覽器的界面是類似的。對于無用戶交換功能的頁面。用戶接觸的界面都是一致的，用戶使用方便。

TopicofB / S structure

Ⅰ.Introduction

B/S is a new pattern information managementsystem(MIS)of platform model , which is based of Web skill and break up the server part of traditional C/S model into a data server and no less than one application server(web server),so that become client system with three structures.The first tier client, it is the interface between the user and the system.Streamline client application to a generic browser software such as Netscape Navigator, Microsoft's IE and so on.Browser HTML code into the illustrated pages.Site also has some interactive features that allow the user to enter information presented to provide background on the web application form and make processing the request.The second layer is the background Web server.The second layer of the Web server will initiate the process to respond to this request, and dynamically generate a bunch of HTML code, the result of which is embedded processing, returned to the client browser.If the request submitted by the client includes a data access, Web server, and database server needs to complete the collaborative processing.The third layer is the database server tasks similar to C/S mode, responsible for coordinating the SQ different Web server sends requests, manage the database.Ⅱ Difference between B / S and C/S

(1)Hardware environment

C/S is generally built on a dedicated network, a small range in the network environment, then provide connectivity and data exchange services between the LAN via a dedicated server.B/S builds on the wide area network, the network does not have to be a dedicated hardware environment, such as telephone access, leased equipment.Information they manage.Than the C/S stronger adaptation, generally as long as the operating systems and browsers on the line.(2)Safety requirements

Relatively fixed C/S is generally user-oriented group of information security controls are strong.Generally highly confidential information systems using C/S structure appropriate.It can publish public information through B/S.B / S based on the wide area network, the security control is relatively weak, the user may for unknown.(3)Program Structure

C/S programs can pay more attention to the process, you can check on the multi-level privileges on the system speed can be less consideration.B/S for security and access speed of multiple considerations, the need to establish more optimal basis.Has higher requirements B/S structure of the application architecture is the development trend of the ratio C/S, from the MS.Net Series the BizTalk 2000 Exchange 2000, a comprehensive support network components to build a system.SUN and IBM push JavaBean component technology, so that B/S is more mature.(4)Software reuse

C/S integrity of the program can be considered unavoidable, reusable component reuse is not as good in B/S requirements under the member.B/S multiple structure, requiring relatively independent functional components.Reuse can be relatively good.Would like to buy a table can be reused, rather than doing a table in a stone wall

(5)System Maintenance

C/S program due to the holistic, whole investigation must deal with the problems and system upgrades.Upgrade difficult.Probably do a new system

B/S component composition, replacement of individual aspects of components, to achieve a seamless system upgrade system maintenance overhead is minimized.Users from the Internet to download the installation can be upgraded.(6)Deal with the problem

C/S can handle fixed user plane, and in the same area, security requirements, and operating system-related needs.Should all be the same system.B/S based WAN, for different user groups, geographic dispersion, which is theC/S can not be done.Relationship with minimum operating system platform.(7)User Interface

C/S Multi-Window platform is built on the limited performance of the method, programmers generally higher.B/S based on the browser, there are more rich and vivid expressions and user communication, And most difficult to reduce, reduce development costs.(8)Information flow

C/S program is usually a typical centralized mechanical handling, relatively low interactivity.B/S flow of information can change, change BB BC BG and other information flows, like trading center.Ⅲ AdvantageofB / S
