专业英语写作Chapter 3 Exercise for essay writing

Exercises1. Study the following topic statements from different essays on the topic of the status of women in Hon, an imaginary country. Which method of organization (time order, exemplification, cause and effect or comparison and contrast) does each one indicate? How many paragraphs will the body of each essay probably contain?1) Although the status of women in Hon has improved remarkably in recent years, it is still very low when compared to the status of women in the countries of the Western world.2) Beginning in World War II and continuing through the period of economic boom, the status of women in Hon has changed remarkably.3) The status of women in Hon has improved remarkably in recent years in the areas of economic independence, political rights, educational opportunities, and social status.4) The status of women in Hon has changed remarkably in recent years due to increased educational opportunities and changes in the country’s law.2. Complete the following topic statements by adding subtopics to them.1) The basic causes of poverty are ____________________________________.2) A teacher must have the following qualities: __________________________.3) Technology is changing our lives in three important areas: _______________.4) Women generally live longer than men for two main reasons: _____________.5) The purpose of this report is to ______________________________________.3. Choose one of the following topics and write an opening paragraph. Be sure to include a topic statement in your paragraph.1) Choosing a career2) Space exploration3) Losing a job4) Pollution and the environment5) Violence on TV4. Write a concluding paragraph for the following opening paragraph. Follow these two steps:1) Summarize the main points or paraphrase the topic statement. Be sure to introduce the conclusion with a transition.2) Add your comments.The busy schedules that most adults face from day to day have created a rising health problem in the modern world. Stress affects almost everyone, from the highly pressured executive to the busy homemaker or student. It can cause a variety of physical disorders, ranging from headaches to stomach ulcers and even alcoholism. Stress, like a common cold, is a problem that can’t be cured; however, it can be controlled. A person can learn to control stress by setting realistic goles, enjoying a hobby and/ or physical exercise, and by maintaining a good, warm relationship with family and friends.Keys1.1) The topic statement indicates that the method of organization should be“comparison and contrast”. Examples of their low status in two or more areas compared with that of women in western societies should be given in this part. So, the body part of this essay will probably contain two or three paragraphs.2) The topic statement indicates that the method of organization should be “timeorder/chronological order”. The introduction of their status during World War II and the period of economic boom will be provided in this part. So, the body part of this essay will probably contain two paragraphs.3) The topic statement indicates that the method of organization should be“exemplification”. The description of women’s status in Hon in the areas of economic independence, political rights, educational opportunities, and social status will be written in this part. So, the body part of this essay will probably contain four paragraphs.4) The topic statement indicates that the method of organization should be “cause andeffect”. Two reasons will be given concerning the improvement in women’ s status.So, the body part of this essay will probably contain two paragraphs.2.1) The basic causes of poverty are lack of knowledge, poor health, laziness (or: overpopulation,low income, big family, natural disaster, geographic location, etc.)2) A teacher must have the following qualities: rich/profound knowledge, patience, humor,willingness to help students, well-prepared lessons,etc.3)Technology is changing our lives in three important areas: ways of communication,convenience in travel, medical care service.4)Women generally live longer than men for two main reasons: less pressure, fewer bad habitsthan men (or: endurance which helps to good health).5)The purpose of this report is to reveal the effect of distance education on lives and choices ofcourses and subjects in distance education.3.1) Choosing a career(1)Now people in growing number are coming to realize that choosing a proper career is one of the most important things in people’s life. If you don’t choose an appropriate career for yourself, you may be depressed, unhappy and lose confidence. Your decision for careercan be decided by your educational background, your interest and the prospect of the trade you are going to enter.•Method of organization: exemplification•Number of paragraphs: three(2)Almost every young person will face the problem of choosing a career sooner or later. What aspects should you consider for your career choice? Personal interest, individual ability, salary level and the prospect of the company you will enter are all very important.•Method of organization: Exemplification (Illustration)•Number of paragraph: Four(3)With the development of our society and the change of our conventional thought, we have more standards to choose a good career nowadays than ever before in the areas of kinds of job, situations of employment and personal interests.•Method of organization: Comparison and contrast/Exemplification•Number of paragraphs: three(4)There’re no certain standards for a person to choose his career, because there’re too many factors which have to be considered. In my opinion, the most important factors are: prospect of the job, location and working-condition.•Number of paragraphs: three•Method of organization: Exemplification (illustration)2)Space exploration:During the last ten years, China makes lots of efforts in space exploration and makes a long-step progress, but when compared with western countries, China will have a long way to go to catch up with some developed countries.•Method of organization: Comparison and contrast•Number of paragraphs: two3)Losing a jobWhat will you do when you lose your job? Of course, different people have different ideas. Optimistic people treat/regard it as a new start while the pessimistic people think it theend of the world.•Method of organization: Comparison and contrast•Number of paragraphs: two4)Pollution and Environment(1)Nowadays, more and more people have realized that the pollution of the environment has been very severe. In some areas you may see a lot of wastes, and also you may see polluted rivers. There are many causes of the pollution of the environment, such as the purpose of earning more money, overpopulation, and lack of advanced waste-disposal techniques.Method of organization: cause and effectNumber of paragraphs: three(2)In recent years, the issue of pollution and the environment has been brought to public attention, it has already become a global problem. Personally, I think there are three causes of environment pollution: industrial arbitrary drainage, lack of human awareness and ineffective government control.Method of organization: Cause and effectNumber of paragraphs: three5)Violence on TV(1)TV, a product of modern technology, plays an important role in our modern lives. In spare time, watching TV is a common way for people to relax and get fun. However, violence on TV, which appears more and more often, should be responsible for the increasing rate of young offenders.Method of organization: Cause and EffectNumber of paragraphs: One or more(2)Over the last decades of years, as a new technology, TV has been becoming as much a part as food in people’s lives, especially for young people. They are absorbed in violent programs which have bad influence on their psychologies and behaviors. (Exemplification; possibly 2 paragraphs)(3)Young people have been exposed to violent TV programs of different degrees from cartoon to violent stories while they have been growing up.(Chronologically, 1 or more)(4)Violence on TV is criticized by sociologists because of its bad influence on children.(Cause and effect, 1 or more)(5)Compared with violence on books, violence on TV has greater influence on young people.(Comparison and contrast, one or more)4.(1)In conclusion, although stress is very popular /may happen to everybody/is a commonly seen feeling, it can be controlled/avoided/prevented/lessened/turned,etc. Doing sth. with proper aims, taking regular sports, getting along well with others can help to get rid of stress. So, in my opinion, if we follow these instructions, we will certainly free ourselves from stress and be in good health both physically and mentally/spiritually.(2)In conclusion, although the busy schedules can make almost everyone suffer from stress, a person can release the stress by sports, by entertainment, and by doing something that is his favorite. In my opinion, health is the most important thing. If a person wants to keep healthy, he must make stress least. In his spare time, he can do anything he likes, and make himself have a good mood. If he does so, stress can’t affect his health badly.。

Zhang Ning: Well, there might many causes for system crash. One of them is software. The simplest operation like installing and uninstalling might cause a crash in system. Problems within the system may also do that, so you have to be very careful when deleting DLL files, modifying Windows registry, or upgrading the operating system. Another cause is the hardware problem. Have you tried backing up the files? It would be a great help in system restoration when the problem doesn’t lie in the hardware. Cheng Hong: The service personnel installed a ghost program for me when I bought the computer. Will I lose the data in my hard disk if it is restored? Qian Liang: Not except the data on C: drive, where files on your desktop or in My Documents are stored. You may move them into other locations with a bootable disk or under DOS if there are any. Cheng Hong: There are a lot of learning materials in My Documents and on the desktop. Would you please help me transfer them? It might save me the trouble of calling for customer services, and what’s more important, I’d learn a lot from you. Qian Liang: No problem.

Real-time operating system (RTOS)
Real-time operating systems are used to control machinery, scientific instruments and industrial systems. Little user-interface capability, and no end-user utilities, since the system will be a "sealed box" when delivered for use. A very important part of an RTOS is managing the resources of the computer so that a particular operation executes in precisely the same amount of time, every time it occurs.

Introduction
Programming languages vary greatly in their sophistication and in their degree of versatility. Some programming languages are written to address a particular kind of computing problem or for use on a particular model of computer system. For instance, programming languages such as FORTRAN and COBOL were written to solve certain general types of programming problems-FORTRAN for scientific applications, and COBOL for business applications.Although these languages were designed to address specific categories of computer problems, they are highly portable, meaning that they may be used to program many types of computers. 编程语言在复杂度和功能性上有很大的不同。 一些编程语言为一个 特殊种类计算的问题或为在计算机系统一个特殊模型使用。 例如,编程 语言FORTRAN和COBOL用于解决某些类型的编程问题,其中,FORTRAN语言 用于科学计算,而 COBOL语言用于解决一般商业应用问题。虽然这些语 言被设计成解决一定类型的计算问题,但他们是非常灵活的,也就说他 们可以被用于解决许多类型的计算。

Other languages, such as machine languages, are designed to be used by on specific model of computer system, or even by one specific computer in certain research applications. The most commonly used programming languages are highly portable and can be used to effectively solve diverse types of computing problems. Languages like C, PASCAL, and BASIC fall into this category. 其他语言,例如机器语言,在计算机系统具体模型被使用,甚 至由一台具体计算机在某些研究应用领域内使用。 最常用的编程语 言,像C、PSACAL、BASIC语言,是非常灵活的,可以有效地解决各 种类型的计算问题。

1.Machine Languages In machine languages, instructions are written as sequences 1s and 0s, called bits, that a computer can understand directly. An instruction in machine language generally tells the computer four things (1) where to find one or two numbers or simple pieces of data in the main computer memory (Random Access Memory, or RAM), (2) a simple operation to perform, such as adding the two numbers together, (3) where in the main memory to put the result of this simple operation, and (4) where to find the next instruction to perform. 在机器语言中,指令是由一些被称为比特的0和1序列组成,它们 是能够被计算机直接理解的。在机器语言中,通常一条指令要告诉计算 机四件事情:(1)到内存的什么地方去取一个或两个数据,或者一个简 单的数据块(2)一个简单的数据操作,例如将两个数相加(3)这个简 单的操作的结果放到内存的什么位置(4)到哪里去找要执行的下一个指 令。

Introduction
Programming languages, in computer science, are the artificial languages used to write a sequence of instructions (a computer program)that can be run by a computer. Similar to natural languages, such as English, programming languages have a vocabulary, grammar, and syntax, However, natural languages are not suited for programming computers because they are ambiguous, meaning that their vocabulary and grammatical structure may be interpreted in multiple ways. The languages used to program computers must have simple logical structures, and the rules for their grammar, spelling, and punctuation must be precise. 编程语言,在计算机科学中,是一种人工语言用于编写可以由计算 机负责操行的指令序列(即计算机程序)。 类似自然语言,例如英语, 编程语言有词汇,语法,并且句法,然而,自然语言并不适用于计算机 编程,因为他们是模棱两可的,也就是说他们的词汇量和语法结构可能 有多种解释方式。被用于计算机编程的语言必须有简单的逻辑结构,并 且他们的语法、拼写和标点的规则一定是精确的。

Language Types
Programming languages can be classified as either low-level languages or high –level languages. Low-level programming languages, or machine languages, are the most directly by a computer. Machine languages differ depending on the manufacturer and model of computer. High-level languages are programming languages that must first be translated into a machine language before they can be understood and processed by a computer. Examples of High-level languages are C,C++,PASCAL, and FORTRAN. Assembly languages are intermediate languages that are very close to machine languages and do not have the level of linguistic sophistication exhibited by other high-level languages, but must still be translated into machine language. 编程语言可以分为低级语言和高级语言。低级语言,或者说机器语 言,是最贴近计算机的语言。机器语言依赖于计算机制造商和计算机模 型。 高级语言是在他们可以由计算机理解和处理之前必须首先翻译成 机器语言的编程语言。 高级语言的例子有:C、C++、PASCAL和FORTRAN。 汇编语言是非常接近机器语言的中间语言,没有其他高级语言的复杂语 法,但是必须仍然翻译成机器语言。
