第三篇：初一英语教案(人教版)Unit2

Unit 2

Nice to meet you!

一、教学目标与要求

通过本单元教学，使学生初步学会日常交际中表示“介绍”（Introduction)"的一些简单用语，并要求学生尽可能在交际场合中使用。继续学习打招呼的常用语句。学习英语字母O~Z的读音与书写形式。学会字母歌。能背诵、默写字母表（含大小写）。

二、教学重点与难点

1、日常介绍用语（2、英语字母O~Z。

三、课时安排

本单元共4课时，每课1课时。

S1:Hello!I'm Jim Green.S2:Hello!I'm Kate Green.叫其他几个学生，分别用I'm„，进行自我介绍。

3、教师叫起一个学生（他或她的真实姓名，教师要知道），然后用他（或她）的真实姓名提问：T：Hello!Are you XXX? 让大家猜一猜这句话的意思。帮助这个同学回答：

S：Yes,I am.教师可板书Yes,I am.让大家猜一猜其含义。

再叫另一位同学，这个学生的真实姓名教师也要知道。但故意问错： T:Hello!Are you XXX? 帮助这个学生回答：

S:No,I'm not.重复刚才的步骤，并对黑板上的答案进行讲解。其中am在肯定回答中不能缩写，因为是强调。在否定回答中可以缩写。关于 am的缩写，学生只是了解一下，能听懂，能说出就可以了。

４、放录音，学生先听，后跟读。反复两至三遍。然后叫起几个学生进行单个练习：

T:Hello!Are you XXX?（用真实姓名）S1:Yes ,I am.T:Hello!Are you XXX?（非真实姓名）S2:No,I'm not.I'm XXX.也可以把学生分成３人一组，进行练习。

５、复习所学过的字母。教师出示卡片，同时问：What's this? 要求学生用It's„回答。教字母O~T,方法同前。q这个字母的读音可能会引起一些麻烦，教师可给予特别注意。６、拿出事先准备好的小黑板，辅导这几个字母的书写格式。示范、操练步骤同前。７、布置作业

１）练习朗读所学日常用语；２）抄写字母O~T,熟练朗读A~T，并能背诵下来；３）练习册 T:Good morning(afternoon)S1:Good morning(afternoon).T:My name is XXX.What's your name? S2:My name is XXX.换一个学生： T:Hello!S2:Hello!T:Are you XXX? S2:Yes, I am.T:How are you ? S2:I'm fine,thank you.And you? T:I'm fime,too.Thank you.在进行以上操练时，注意操练形式的多样性。既要有集体操练，又要有个人或小组之间的操练。在初级阶段，学生往往容易适应进行“应答”式的操练，即教师先用英语与学生打招呼，学生进行呼应。为使学生能主动、自觉地运用所学英语去进行“交际”，教师可从现在起，开始培养学生这方面的能力，并激发学生用英语进行交际的欲望。从本课起，教师可进行以下带有明显启发式的操练：

请两个学生到前面来，教师把他们分为Ａ、Ｂ角色，然后用汉语介绍一下情景：

Ｔ：现在是早上，你们两个人在路上相遇了，甲（Ａ）先说什么？乙（Ｂ）怎么应答？这样，启发学生进行以下对话：

S1:Good morning.S2:Good morning.T:同学们从各个小学来到这里，有很多新同学要结识，如果你想询问某一个同学的名字。应该怎样问呢？

启发学生进行以下对话：

S1：Hello!My name is XXX.What's your name? S2:My name is XXX.到目前为止所学过的对话，教师都可以用这种为学生设计一个情景的方式，启发学生主动运用所学英语进行交际。这种作法要坚持下去，学生的交际能力会在这样的操练中，有效地提高；在很多学生中存在的只能被动地去附合、呼应教师的现象，也会在很大程度上有所改变。

2、复习“1~5”数词的说法，教“6~8”这几个数词的读音（学生能听懂、分辨即可）。

3、请两位同学到前面，教师用汉语向全班交待，他们中一个扮演Jim,另一人扮演韩美美。教师转向扮演Jim的同学：

T:Hello, Jim.S1:Hello,Mr(Ms)XXX（教师的Family Name）.T:(Pointing to S2)This is Han Meimei.(Pointing to S1)Han Meimei ,this is Jim.启发全班同学：这时应说什么？之后教师给出答案：Nice to meet you.解释这句话的意思，并说明答语出是

4、放录音。S2:Hello,Li Lei.S1:Jim,this is Han Meimei.Han Meimei,this is Jim.S3:Hello,Jim!Nice to meet you.S2:Hello,Han Meimei!Nice to meet you.S3:How are you? S2:Fine,thank you.And you ? S3:I'm OK.教师可将全班分为3大组（例如，每两行为一大组），每大组分别扮演一个角色，与在前面表演的同学进行同步会话。

如果时间允许，可再叫几名同学到前面来表演；或就近将学生分为三人一组进行练习。教师可到学生中间听一听，对有困难的同学提供帮助。

6、复习A~T，方法同前；教U~Z，具体步骤可参考前面的方法。

7、布置作业

1）练习朗读本课日常用语，并能用This is „的句型，向别人进行介绍；2）抄写本课中所学字母，要求会背诵字母表。

四、交际用语

1.This is Wei Hua.Wei Hua,this is Jim.这是卫华。卫华，这是吉姆。This is „是用来进行介绍的句式。如果是自我介绍，可以说：

Let me introduce myself.My name is „我来自我介绍一下，我叫„„ 一般当听完对方的介绍后，要主动说： Nice to see you!很高兴见到你！

2、Nice to meet you!见到你很高兴！

这是一种问候用语，一般在双方刚认识后讲这句话，表示很高兴结识对方。答语是：见到你我也很高兴！此外，当两位熟人或朋友见面，也可用Nice to meet/see you.或Nice to seee you again。表示问候。

nice的词义除表示“令人愉快的”以外，还有“漂亮的，好的”等意思。例如：That's a

nice boy.那是个好孩子。It's a nice car.那辆汽车真漂亮。

课本核对。

4、翻到彩色插图 a)T:Good morning(afternoon).S:„ b)T:Hello!Are you„?

S:„ c)T:What's your name? S:„ d)T:How are you? S:„

Software Knowledge

3.1 Data Structures 3.2 Operating System 3.3 Programming Languages 3.4 Software Engineering

3.5 Software Testing and Maintenance

3.2 Operating System • The purpose of an operating system is to provide an environment in which a user may execute programs.• Operating systems exist because they are a reasonable way to solve the problem of creating a usable computing system.• The primary goal of an operating system is convenience for the user.• A secondary goal is efficient operation of the computer system.Resource Management

• The operating system provides the means for the proper use of these resources in the operation of the computer system.• We can view an operating system as a resource allocates.• The operating system sets up the order in which programs are processed, and defines the sequence in which particular jobs are executed

教师: 游彦 计算机专业英语

第3章 Software knowledge

• I/O Management

• To facilitate execution of I/O operations, most operating systems have a standard set of control instructions to handle the processing of all input and output instructions.• These standard instructions, referred to as the input/output control system(IOCS), are an integral part of most operating systems.• The controlling software calls on the IOCS software to actually complete the I/O operation.Classification of Operating Systems

• A single-user operating system expects to deal with one set of input devices—those that can be controlled by one user at a time.• A multi-user operating system is designed to deal with input, output, and processing requests from many users-all at the same time.• A network operating system provides communications and routing services that allow computers to share data, programs and peripheral devices.• A multitasking operating system provides process and memory management services that allow two or more programs to run simultaneously.• All modern operating systems are multitasking and can run several processes simultaneously.教师: 游彦 计算机专业英语

第3章 Software knowledge

• A desktop operating system is one that is designed for a personal computer—either a desktop or notebook computer.•

3.3 Programming Languages • A programming language or computer language is a standardized communication technique for expressing instructions to a computer.• A language enables a programmer to precisely specify what data a computer will act upon, how these data will be stored/transmitted, and what actions to take under various circumstances of cases.• Programming languages are important tools for helping software engineers write better programs faster.Procedural programming and Object-oriented programming • Procedural programming involves using your knowledge of a programming language to create computer memory locations that can hold values and writing a series of steps or operations that manipulate those values.• A single procedural program often contains hundreds of variable and thousands of procedure calls.• Object-oriented programming is an extension of procedural programming in which you take a slightly different approach to writing computer programs.教师: 游彦 计算机专业英语

第3章 Software knowledge

• Writing object-oriented programs involves both creating objects and creating applications that use those objects.Machine Language

• An executable program is a sequence of extremely simple instructions known as machine code.• Machine code instructions are binary—that is, sequences of bits(0s and 1s).• Because these numbers are not understood easily by humans, computer instructions usually are not written in machine code.Assembly Language

• Assembly language uses commands that are easier for programmers to understand than are machine-language commands.• Each machine language instruction has an equivalent command in assembly language.• Assembly language is sometimes inserted into a high-level language program to carry out specific hardware tasks or to speed up a high-level program.High-Level Languages

• If the computer could translate convenient symbols into basic operations, why couldn’t it also perform other clerical coding functions? • A high-level programming language is a means of writing down, in

教师: 游彦 计算机专业英语

第3章 Software knowledge

formal terms, the steps that must be performed to process a given set of data in a uniquely defined way.• The high-level languages are often oriented toward a particular class of processing problems.Compiler and Interpreter

• A complier is a program that translates source code into object code.• Every high-level programming language comes with a compiler.• Because compilers translate source code into object code, which is unique for each type of computer, many compilers are available for the same language.• An interpreter translates high-level instructions into an intermediate form, which it then executes.• The advantage of an interpreter, however, is that it does not need to go through the compilation stage during which machine instructions are generated.•

3.4 Software Engineering • Software engineering is the application of tools, methods, and disciplines to produce and maintain an automated solution to a real-world problem.• Software engineering first emerged as a popular term in the title of

教师: 游彦 计算机专业英语

第3章 Software knowledge

a 1968 NATO conference held in Garmisch, Germany.• A large-scale software projects spans a considerable period of time.A number of distinct phases can be identified over this period of time.Together, these make up what is known as the “software life cycle”.The software life cycle

• Requirements definition: The requirements of the software are established and specified.• Design: A design is developed from an analysis of the requirements.• Implementation: The design is coded in a particular programming language on a particular machine.• Testing: The implemented system is tested to see that it meets the specified requirements.• Operation and maintenance: The system is installed and used.Errors found must be repaired.Requirements definition • The first phase, requirements definition, refers to the period during which the requirements of the system desired, that is, it’s functional characteristics and operational details, are specified.• The input to this phase is the stated(often rather loosely stated)needs for the software.教师: 游彦 计算机专业英语

第3章 Software knowledge

• Typically, a “requirements document” is the output of this phase, a set of precisely stated properties or constraints that the final product must satisfy.• As with any of the phases, it is important that errors not be allowed to move into subsequent phases.Design • The second phase, design, is predominantly creative, while some would argue that creativity is inherent and cannot be trained or improved, it can certainly be enhanced by the use of good procedures and tools.• The input to this phase is a(debugged and validated)requirements document: the output is a design expressed in some appropriate form(for example, pseudo-code).• Each requirement in the requirements document must have a corresponding design fragment to meet it.Implementation • The third phase, implementation, is the actual coding of the design developed in the second phase.• The lure of this phase is strong, and many a foolhardy programmer has been drawn to it before adequately laying the groundwork in the first two phases.• As a result, requirements are incompletely understood and the

教师: 游彦 计算机专业英语

第3章 Software knowledge

design is flawed.• The implementation proceeds blindly, and many problems arise as a result.Testing

• The fourth phase, testing, is concerned with demonstrating the correctness of the implemented program.Inevitably some testing is performed as part of the previous two phases as well.• Any experienced programmer mentally tests each line as it is produced and mentally simulates the execution of any module prior to any formal testing stage.• A “successful” test run means only that no errors were uncovered with the particular circumstances tested;it says nothing about other circumstances.• In theory, the only way that testing can show that a program is correct is if all possible cases are tried(known as an exhaustive test), a situation technically impossible for even the simplest programs.Program maintenance

• The fifth phase is program maintenance phase.Student programmers, unfortunately, rarely become involved in this phase.• Its importance in the real world, however, cannot be overemphasized, since the cost of maintaining a widely used

教师: 游彦 计算机专业英语

第3章 Software knowledge

program can match or exceed the cost of developing it.• Unlike hardware maintenance, software maintenance deals not with repair of deteriorated components, but with repair of design defects, which may include the provision of added functions to meet new needs.教师: 游彦
