请假条(written request for leave)是常用应用文之一，用于向老师或上级领导等因身体状况不好或因某事请求准假的场合。它包括请病假(note for sick leave)和请事假(leave of absence)。

称呼是dear miss lu，写在左上角。请假条因是向老师或上级请示，一般以dear...,或my dear...,开头。有时可在dear之后，用上mr.或miss等的称呼加上姓氏。有一点要注意，各种称呼后面一般都用逗号。

英文请假条格式

请假条(written request for leave)是英语学习者必须掌握的常用应用文之一，它包括请病假(note for sick leave)和请事假(leave of absence)。请假条是用于向老师或上级领导等因身体状况不好或因某事请求准假的场合。

英文请假条写作需注意三点：

1.英文中请假条的写法和汉语请假条相同，它一般由四部分组成，即时间、称呼、正文和签名。

2.一般而言，可认定请假条是一种简单的书信文体。请假条一般写在纸上，不用信封。其书写格式与书信有很多相似之处，是书信的大大简化。

3.请假条的特点是要求开门见山、内容简短、用词通俗易懂。

【范文例析】

假如你是王立。昨天你和同学们去农场帮助农民们摘苹果，不幸(unluckily)从梯子上摔下来伤了腿，但伤得不重。医生让你在家里好好休息。因此，你向高老师请假两天(ask for leave for two days)。(2002新疆乌鲁木齐中考题)【参考范文】

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 【点评】这是一份采用书信格式写的请假条。日期是September 28, 日期写在正文的右上角。由于请假条的内容大多是当天、近几日因病或因事请假，所以不必写上年份；称呼是Dear Miss Gao，称呼写在左上角。请假条因是向上级请示，一般以Dear...,或My dear...,开头。有时可在Dear之后，用上Mr.或Miss等的称呼加上姓氏。不过，有一点仍要提醒大家，各种称呼后面一般都用逗号。正文谈了一件事：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.简洁明了，用词口语化。写请假条只要把请假的理由和请假时间说清楚即可。有的请假条为了说明其请假事由是真实的，在正文之后另起一行，写上I enclose a doctor''''s certificate.(我附上了医生证明。)；签名为Wang Li。签名(署名)写在右下角，签名(署名)上面一行可以写上Yours, Your student等字样，有时由于写条的人和收条的人彼此一般很熟悉，所以在称呼和签名上比较随便和简单。特别是在签名部分，有时可简单到只写个姓或只写个名就可以了。

第四篇：BS100字英文介绍

B/S模式

一、介绍

B/S模式是一种以Web技术为基础的新型的管理信息系统（简称MIS）系统平台模式。把传统C/S模式中的服务器部分分解为一个数据服务器与一个或多个应用服务器(Web服务器)，从而构成一个三层结构的客户服务器体系。

第一层客户机，它是用户与整个系统的接口。客户的应用程序精简到一个通用的浏览器软件，如Netscape Navigator，微软公司的IE等。浏览器将HTML代码转化成图文并茂的网页。网页还具备一定的交互功能，允许用户在网页提供的申请表上输入信息提交给后台，并提出处理请求。这个后台就是第二层的Web服务器。

第二层Web服务器将启动相应的进程来响应这一请求，并动态生成一串HTML代码，其中嵌入处理的结果，返回给客户机的浏览器。如果客户机提交的请求包括数据的存取，Web服务器还需与数据库服务器协同完成这一处理工作。第三层数据库服务器的任务类似于C/S模式，负责协调不同的Web服务器发出的SQ请求，管理数据库。

二、B/S和C/S的区别

1．硬件环境不同：

C/S 一般建立在专用的网络上，小范围里的网络环境，局域网之间再通过专门服务器提供连接和数据交换服务。

B/S 建立在广域网之上的，不必是专门的网络硬件环境，例如电话上网，租用设备.信息自己管理.有比C/S更强的适应范围，一般只要有操作系统和浏览器就行。

2．对安全要求不同

C/S 一般面向相对固定的用户群，对信息安全的控制能力很强。一般高度机密的信息系统采用C/S 结构适宜。可以通过B/S发布部分可公开信息。

B/S 建立在广域网之上，对安全的控制能力相对弱，可能面向不可知的用户。

3．对程序架构不同

C/S 程序可以更加注重流程，可以对权限多层次校验，对系统运行速度可以较少考虑。

B/S 对安全以及访问速度的多重的考虑，建立在需要更加优化的基础之上.比C/S有更高的要求 B/S结构的程序架构是发展的趋势，从MS的.Net系列的BizTalk 2000 Exchange 2000等，全面支持网络的构件搭建的系统。SUN 和IBM推JavaBean 构件技术等，使 B/S更加成熟.。

4．软件重用不同

C/S 程序可以不可避免的整体性考虑，构件的重用性不如在B/S要求下的构件的重用性好。

B/S 对的多重结构，要求构件相对独立的功能.能够相对较好的重用.就如买来的餐桌可以再利用，而不是做在墙上的石头桌子

5．系统维护不同

C/S 程序由于整体性，必须整体考察，处理出现的问题以及系统升级.升级难.可能是再做一个全新的系统

B/S 构件组成，方面构件个别的更换，实现系统的无缝升级.系统维护开销减到最小.用户从网上自己下载安装就可以实现升级。

6．处理问题不同

C/S 程序可以处理用户面固定，并且在相同区域，安全要求高，需求与操作系统相关.应该都是相同的系统。

B/S 建立在广域网上，面向不同的用户群，分散地域，这是C/S无法作到的。与操作系统平台关系最小。

7．用户接口不同

C/S 多是建立的Window平台上，表现方法有限，对程序员普遍要求较高。B/S 建立在浏览器上，有更加丰富和生动的表现方式与用户交流.并且大部分难度减低，减低开发成本。

8．信息流不同

C/S 程序一般是典型的中央集权的机械式处理，交互性相对低。

B/S 信息流向可变化，B-B B-C B-G等信息、流向的变化，更像交易中心。

三、B/S的优点

1、系统开发、维护、升级方便

每当服务器应用程序升级时，只要在服务器上升级服务应用程序即可，用户计算机上的浏览器软件不需要修改，系统开发和升级维护方便.2、B/S模式具有很强的开放性

在B/S模式下，用户通过通用的浏览器进行访问，系统开放性好。

3、B/S模式的结构易于扩展

由于Web的平台无关性，B/S模式的结构可以任意扩展，可以从包含一台服务器和几个用户的小型系统扩展成为拥有成千上万个用户的大型系统.。

4、用户使用方便

B/S模式的应用软件都是基于Web浏览器的，而Web浏览器的界面是类似的。对于无用户交换功能的页面。用户接触的界面都是一致的，用户使用方便。

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

(1)Convenient to update、maintain and develop System.Whenever a server application upgrades, as long as you can upgrade the service application on the server, the browser software on the user's computer without modification, systems development and upgrading maintenance.2、strong open

In the B/S mode, the user access through a common browser, system openness is good.(2)strong open

In the B / S mode, the user access through a common browser, system openness is good.(3)easy to extend

Because the Web is a platform-independent, structural B/S mode can be arbitrarily extended, can contain from one server and several small systems users have thousands of users expanded into large systems

(4)Easy to use

B/S mode applications are based on a Web browser, and a Web browser interface is similar.For non-users switching pages.User contact interface are the same, the user easy to use.阎晓燕
