提高英文科技论文阅读水平重要性

1、提高英文科技论文阅读水平重要性摘 要 提高英文科技论文阅读水平有助于提高科学 技术的创新水平。本文结合科技英语教学中的实例分析了多 种语法衔接和词汇衔接方法，利用多种衔接方法提高英文科 技论文阅读水平。关键词英文科技论文 语法衔接词汇衔接中图分类号：h319.3文献标识码：a科学技术是第一生产力，科学技术的创新离不开科技论 文。通常人们将科技会议论文和科技期刊论文统称为科技论 文。科技论文按写作语言的不同可分为中文科技论文和外文 科技论文。外文科技论文以英文科技论文为主。英文科技论 文比中文科技论文的数量多。众多的科研成果以英文科技论 文形式发表，因此很有必要提高英文科技论文的阅读水平。科技论

2、文与科普文章不同。科普文章是写给公众看的， 它具有一定的文学性和艺术性。科技论文是写给同行专家看 的，它具有很强的逻辑性。科技论文的逻辑性在文字上表现 为句子之间的衔接十分紧密，因此掌握句子之间的各种衔接 方法有助于提高英文科技论文的阅读水平。1语法衔接语法衔接包括省略、替代、照应和连接等多种方法，这些方法有助于增强英文科技论文的逻辑性和连贯性。(1) computers exist in a wide range of sizes and power. (2) the smallest are embedded within the circuitry of appliances, such

3、 as televisions and wrist watches.句(2)中the smallest后面省略了在上文句(1)中 已经出现的computerso采用省略的衔接方法避免了在句(2) 中重复出现computers,突出了句(2)中的新信息“the smallestw ,使得句子之间更加紧凑。(3) laptop computers and pcs are typically used in businesses and at home to communicate on computer networks, for word processing, to track finance

4、s, and to play games.(4) they have large amounts of internal memory to store hundreds of programs and documents.(5) in 1975, gates and paul allen collaborated on the first version of the basic programming language(6) this led to the formation of microsoft in albuquerque, new mexico, in the same year

5、句(4)用人称代词they指上文句(3)中的laptop computers and pcs,用人称代词起到照应的作用。句(6) 用指示代词 this 指前面 in 1975, gates and paul allen collabora ted on the firs t version of the basic programming language整个句子所表达的意思，用指示代词 起到照应的作用。这种照应的衔接方法使得科技论文更加简 洁，表达的意思更加清晰。(7) a laser used with the erbium-doped fiber can then be triggere

6、d without first having to convert weakened light pulses into electrical signals(8) as a resuit, with no intervening optical / electronic conversions to slow down transmissions, fibers can carry more information in the form of higher speed signals.句(8)中的as a result表示句(7)与句(8)之间 是一种因果关系。还有一些过渡性的词语可以表示

7、转折、时 间、条件和因果等逻辑关系。掌握起衔接作用的过渡性词语, 有助于把握科技论文的内在逻辑。2词汇衔接为了进一步增强英文科技论文的逻辑性和连贯性。英文 科技论文除了应用语法衔接的方法，还大量使用词汇衔接的 方法。词汇衔接包括重复、同义、反义、上下义等多种方法。(9) the secret to perfect timing is to make an extra satellite measurement.(10) if three perfect measurements can locate apoint in 3-dimensiona.l space,then four imperf

8、ect measurements can do the same thing.句(9)中出现了 measurement (单数形式)，句(10) 中又重复出现了 measurements (复数形式)，这种词汇重复 方法不但使得两个句子更加紧密，而且突出了论文要表达的 重要信息(measurement)o(11) if everything were perfect (i.e. if our receiver s clocks were perfect) then all of our satellite ranges would intersect at a single point (wh
