  17. Using Digital Technologies to Succeed in Your Career - Computer Based Professions Software engineers Design and develop new programming applications Computer scientists Use computers to help with the software design process Science and Mathematics Scientists are using computers to analyze string theory equations

  18. Business and Communications Most businesses succeed in using technology to increase revenues or reduce costs In factories Computers are being used to design and manufacture products, using Computer-assisted design (CAD) and Computer-assisted manufacturing (CAM)

  19. Science and Mathematics Scientists are using computers to Analyze string theory equations Forecast weather Hunt for hurricanes Analyze the environmental impact of forest fires, Make detailed maps using geographic information systems (GISs)

  20. Engineering Engineers use computers In design and operations To monitor and control petroleum refinery operations To make sure that sophisticated refinery towers and systems are efficiently and safely operating To make complex thermodynamics, power consumption, and circuits and signal

  21. Sports Computers Have been used in all aspects of sports, nutrition/营养/, and exercise Used to design football equipment that reduces the chance of permanent paralysis or brain damage Can be used to analyze diet and nutrition for athletes /运动员/

  22. Medicine and Health Care Electronic health records (EHRs) Can improve health care Can reduce health care costs by billions of dollars annually Medical informatics An area of medicine involved with storing medical records in a digital format on a national database

  23. Criminology, Law Enforcement, and Security Computers Used extensively in criminology, law enforcement, and security Provide crime fighters with invaluable information on criminals, stolen vehicles, and missing persons Can be used to capture facial thermograms

  25. Information Security Information security refers to the protection of information systems and the information they manage against unauthorized access, use, manipulation, or destruction, and against the denial of service to authorized users. Hackeran individual who subverts computer security without authorization.

  26. Information technology The (especially computerised or electronic) technology related to the gathering, recording and communication of information Applied computer systems - both hardware and software, and often including networking and telecommunications, usually in the context of a business or other enterprise 27

  27. Why study IT? IT has changed the ways in which we communicate and reach decisions IT has changed the way in which work is done, which brings benefits but also imposes strains IT has created its own job-markets – using IT and making IT We need to think a bit about what all this IT is doing, and where it’s leading us 28

  28. The future of IT The development of products (devices and systems) and concepts (ideas and procedures) The application of these products and concepts to specific areas of human activity 29

  29. Information systems “A set of interrelated /相关的/components that sense/检测/, communicate, analyse, and display information for the purpose of enhancing our perceptions/认知/, understanding, control, and creative ability“(Laudon, Information technology and society, 1996) Analysing Output Sensing &communicating Input Processing Output 30

  30. Data and Files Data - symbols that represent people, events, things and ideas Computers store data in digital format as a series of 1s and 0s. Each 1 or 0 is called a bit Eight bits is called a byte 31

  31. A named collection of data that exists on a storage medium A data file contains data such as the text for a document An executable file contains the programs or instructions that tell a computer how to perform a specific task A filename extension indicates a file’s contents .exe or .EXE .gif or .GIF What is a file? examples 32

  32. 科技英语的特点 一、复杂长句多 科技文章要求叙述准确，推理谨严，因此一句话里包含三四个甚至五六个分句的，并不少见。译成汉语时，必须按照汉语习惯破成适当数目的分句，才能条理清楚，避免洋腔洋调。这种复杂长句居科技英语难点之首，要学会运用语法分析方法来加以解剖，以便以短代长，化难为易。例如： Factories will not buy machines unless they believe that the machine will produce goods that they are able to sell to consumers at a price that will cover all cost. 这是由一个主句和四个从句组成的复杂长句，只有进行必要的语法分析，才能正确理解和翻译。现试译如下： 除非相信那些机器造出的产品卖给消费者的价格足够支付所有成本，否则厂家是不会买那些机器的。 节译：要不相信那些机器造出的产品售价够本，厂家是不会买的。 后一句只用了24个字，比前句40个字节约用字40%，而对原句的基本内容无损。可见，只要吃透原文的结构和内涵，翻译时再在汉语上反复推敲提炼，复杂的英语长句，也是容易驾驭的。

  33. 科技英语的特点 二、被动语态多 英语使用被动语态大大多于汉语，如莎翁名剧《罗密欧与朱丽叶》中的一句就两次用了被动语态： Juliet was torn between desire to keep Romeo near her and fear for his life, should his presence be detected. 朱丽叶精神上受到折磨，既渴望和罗密欧形影不离，又担心罗密欧万一让人发现，难免有性命之忧。 科技英语更是如此，有三分之一以上用被动语态。如： No work can be done without energy.

  34. 科技英语的特点 三、非谓语动词多 英语每个简单句中，只能用一个谓语动词，如果读到几个动作，就必须选出主要动作当谓语，而将其余动作用非谓语动词形式，才能符合英语语法要求。 非谓语动词有三种：动名词、分词（包括现在分词和过去分词）和不定式。例如： 要成为一个名符其实的内行，需要学到老。 这句中，有“成为”、“需要”和“学”三个表示动作的词，译成英语后为： To be a true professional requires lifelong learning. 可以看出，选好“需要”（require）作为谓语，其余两个动作：“成为”用不定式形式 to be，而“学”用动名词形式learning，这样才能符合英语语法要求。

  35. 科技英语的特点 四、词性转换多 英语单词有不少是多性词，即既是名词，又可用作动词、形容词、介词或副词，字形无殊，功能各异，含义也各不相同，如不仔细观察，必致谬误。例如, light 名词：(启发)in (the)light of由于，根据； (光)high light(s) 强光，精华；(灯)safety light 安全指示灯 形容词：(轻)light industry 轻工业； (明亮)light room 明亮的房间； (淡)light blue 淡蓝色； (薄)light coating 薄涂层 动词： （点燃）light up the lamp 点灯 副词： （轻快）travel light 轻装旅行 （容易）light come, light go 来得容易去得快 诸如此类的词性转换，在科技英语中屡见不鲜，几乎每个技术名词都可转换为同义的形容词。词性转换增加了英语的灵活性和表现力，读者必须从上下文判明用词在句中是何种词性，而且含义如何，才能对全句得到正确无误的理解。
