第三篇:资源环境专业英语演讲稿
Good morning everyone,I am from class 3, my name is Su Peida.I am pleased to have a chance to stand of our group to stand here.Today, our team’s topic is “group members also include Lan Liangzhang, Luo Jinqiang, and Lin Xiongzhi.Then I will have a sample introduce about our t Lin xiongzhi and I made the ppt together.Lan liangzhang was in charge of collecting pictures, and Luo jinqiang wrote the speech draft.Now, let’s begin our topic.I will show you From the photos, we will find we are fortunate, because we have a grand country and our GDP is just second to American.Our economy has developed rapidly.Then, I will show you From the first photos, we know, human are become more and more well and perfect, but the resources-environment are become more and more poor and rare.But, do you think what cause it lead to such phenomenon.Maybe you haven’t thanked that.And, I will tell you the truth behind the development of economy.the mid-20th century, the rapid development of industrial and transportation has caused the which harms to human health, effects the growth of plants and animals, damage building materials, and even changes the earth's climate.A survey shows that more than every year caused by air pollution.Secondly, our water pollution question is extremely serious.The widespread around the drinking water security problems are threat to human survival directly.Although a large amount of fund has been put into these years, the effect is not obvious;the overall situation is still deteriorating.Heavy Metal Pollution is the main way of soil pollution.And the heavy metal is from chemical factory.We can see a table.The situation of land desertification and soil erosion is very serious.In addition, the quality of cultivated land in our country down very quickly.At the same time, the excessive use of pesticides has caused serious pollutions of cultivated land, which
directly related to food safety issues of our residents.It is not denied that our economy has developed rapidly, and our GDP is second to America.But from the fact of environment, we can find our economy is just base will have not a place to stay, and even we also disappear.So we call for everyone to remember it, environment is the first, and the economy is second to it.Thank you!

四、课文填空:UNIT13的第一部分(1、Pollution of streams and rivers)PoHution of Streams and Rivers
When sewage is discharged into a freshwater stream,the stream becomes pollution。This does not mean that the oxygen content drop instantaneously。But the potential for oxygen depletion exists wherever there is sewage。The measure of this potential is the BOD, which rises as soon as the sewage goes in。Now follow the water downstream from “Polutionville.” There processes are going on, all at the same time.Process1.The bacteria are feasting on the sewage.because of this action,the amount of sewage in the water is decreasing,so the BOD is going down。
Process2.As the bacteria consume the sewage,they also use dissolved oxygen,so that concentration,too,start to decrease。
Process3.some of the lost oxygen is being replenished from the atmosphere and form photosynthesis by the vegetation in the stream。
For the first 50km or so downstream, the natural ability of the river to recover its oxygen(process3)simple cannot keep up with the feasting bacteria(process2),so the dissolved oxygen concentration goes down。The fish begin to die,but it is not the sewage that is killing them。(In fact,the sewage provides food.)Instead,the fish die from lack of oxygen,beginning when the dissolved oxygen concentration falls below about 4mg per liter,depending on the particular species。
The fish kills start about 15km downstream from the introduction of the raw sewage。In time,as the sewage is used up by bacteria,the BOD goes down(process1),the consumption of oxygen also slows down,and the natural ability of the river to recover(process3)becomes predominant。The river then begins to repurify itself。About 90km downstream the fish begin to survive again,and at about 140km the oxygen content has increased to its former,unpolluted level。
Of course,if additional sewage is discharged before recovery is complete,as shown in the illustration at 160km,the river becomes pollution again。When sources of pollution are closely spaced,pollution becomes practically continuous。Rivers in such a condition,which unfortunately can be found near densely polluted areas all over the world,support no fish,are high in bacterial content(usually includingpathogenic organisms),appear muddily bluegreen from choking algae,and,in extreme cases,stink from putrefaction and fermentation。
第五篇:专业英语
我国经济和科学技术正在高速发展,随着我国机械行业实力的不断提升,中国正在加速产品与设备的更新与改造,我国与其他国家在各技术领域也正在实现进一步的合作,许多企业引进了很多进口设备,大量资料是英文原版的。因此,学生将来在工作岗位上能否读懂这些资料就是摆在面前的一个严峻的问题,特别是在生产实际中碰到现场实际问题的时候,很可能需要查阅原版英文资料或与相关专家用英语交流专业技术来谋取解决途径,所以机械工程专业英语的掌握就变得越来越重要。
一、学习机械专业英语面临的主要问题
1.缺乏足够的重视,认为没必要
许多学生对专业英语重视不够,认为自己以后在工作岗位上一般用不上,学起来又不容易,不想花功夫去学习和加强专业英语方面的能力,即便有专业英语课程也是抱着及格万岁的思想,敷衍了事。其实,随着社会的发展,各种工作岗位对人才的要求越来越高,即使作为一名操作工,也有很大可能要面对纯英文的说明书、加工图纸等专业文献,更无须说将来担任管理和领导岗位对专业英语的需求了。
2专业基础知识不扎实
专业基础不扎实、专业知识的缺乏是专业英语学习和翻译的一大障碍。只有既懂外语又懂专业的人才能适应全面的对外开放,4.无法适应专业英语本身的特点
专业英语一般内容较为枯燥,阐述的是原理概念,结构严谨,不注重文字修饰,重在客观事实;专业词汇多,逻辑性强,理论推导多,有独特的文体形式和表达方式。在学习开始阶段,我感觉很难适应。
二、大学生学好机械专业英语的方法
1.把握专业知识
必须将机械专业知识与英语知识相结合。缺乏专业知识,翻译专业文献就没有了根基,成了无本之末。也许自己在学习过程中就会对翻译出来的东西拿捏不稳,或者自己都不明白,更不能保证对错了。所以,学生必须加强开设本课程前的相关专业知识的学习,为本课程的学习扫清这方面的阻碍,减轻负担。也有学生反映,专业英语学完以后,英语和专业两方面都有所巩固和加强,所以学生要做的仍旧是树立信心,保持良好积极的心态。
2.积累专业词汇和专业术语
在专业英语的学习过程中,学生既要巩固基础词汇,也要学习专业词汇,更要注重基础词汇的习惯用法、含义和在专业英语中的特殊用法、含义,同时,学生还需要在识记专业词汇的同时,掌握一定量的词根、词缀[7]。提高专业英语资料的阅读能力必须扩大词汇量,掌握一定量的专业词汇。如果词汇量掌握得不够,阅读时就会感到生词多,障碍大,不但影响阅读的速度,而且影响理解的程度,从而不能进行有效的阅读,还容易使人产生挫败感。而学生要想扩大词汇量,就必须在阅读的同时进行识记,并扩大阅读范围。
3培养浓厚兴趣
培养对英语的兴趣至关重要。“兴趣是最好的老师”,兴趣是学习英语的巨大动力,有了兴趣,学习就会事半功倍。我们都有这样的经验:喜欢的事,就容易坚持下去;不喜欢的事,是很难坚持下去的。而兴趣不是与生俱来的,需要培养。必须要用正确的态度对待英语学习,用科学的方法指导学习。多让自己去尝试,通过努力让自己体会成功的愉悦。
三、结语
用英语进行专业交流是学习机械工程专业英语的最终目的。由于翻译过程是个创造性的、从生疏到熟练的过程,只有具备刻苦的精神、严肃认真的学习态度和一定的英语水平、专业水平和汉语表达水平,才能充分理解原专业文献的含义,把握原文的想要表述的实质内容,运用种种表达手段和翻译技巧,用准确流畅的符合汉语言习惯的语言生动地再现原文。所以,为把自己培养成为复合型、有发展后劲的高技能人才,大学生必须把握机械工程专业知识,培养专业英语的学习兴趣,积累专业英语学习方法和基础知识,加强英文原始专业文献的阅读,扩大知识面,迅速而切实地提高自己的专业英语的应用能力,为将来更好地适应高素质工作岗位和进一步发展的需要打下良好的基础。
