㈡ 中学生英语关于科技的演讲稿 急求
同学们：
当你们看着可爱的动画片，玩着迷人的电脑游戏，坐上快速的列车，接听着越洋电话的时候，……你可曾意识到科学的力量，科学不仅改变了这个世界，也改变了我们的生活，科学就在我们身边。
翻开20世纪的壮丽篇章，我们发现人类在这百年中不仅经历了血与火的洗礼，更创造了无数科学奇迹。19世纪法国著名科幻小说家凡尔纳的虚构，当时让人不可思议，他所幻想的登月旅行、飞机、远射程炮等，在20世纪都一一成为现实。在21世纪的今天，高科技更是无处不在。
作为跨世纪的一代，我们又该以怎样的姿态去适应新世纪，担起新世纪的重担呢？ 科学技术的日新月异，使得科学不只为尖端技术服务，也越来越多地渗透到我们的日常生活之中，这就需要正处于青少年时代的我们热爱科学，学习科学。参加科技“五小”比赛、阅读科技书籍，使我明白了许多道理。精密的机器人，不用燃料的汽车，虚拟的足球赛，高科技信息的传送等等，一个个生动有趣的现象，激起了我探索科学的愿望。
我们每个人都要学习科学，传播文明，在享受新生活的同时，更要创造新生活，如今，科技产品的更新换代不断加快，可视电视、电脑上网、心脏起搏器，已经不算新鲜了。从1901年发明的真空吸尘器，到人造地球卫星、载人宇宙飞船，科技在不同领域里显示出了强大的力量。电子产业、通讯技术的日益普及，纳米技术、超导材料的广泛应用，不久的一天，也许就在你的餐桌上，会出现像太空青椒、人造牛排等生物工程食品。学习科学技术，不仅仅是为了成为科学家，也是为了能适应生活，更为了能成为新世纪的主人，担起新世纪，为国家建设，为人类文明做出贡献。
新中国成立以来，我国的科技发展突飞猛进，人工合成胰岛素、断手再植、杂交水稻、爆炸原子弹和氢弹、发射人造卫星和飞船等等，这些令世人瞩目的科技成就，大大缩短了我国和先进国家的科学技术的差距，为我国的现代化建设注入了活力。邓小平爷爷说“科学技术是第一生产力”，的确如此，科学为我们祖国的腾飞插上了翅膀。毛泽东主席曾对青年说，世界是你们的，也是我们的，但归根结底是你们的。这句话，饱含了长辈们对我们的殷切期望。如果说长辈们用辛勤的劳动建设了20世纪的祖国，那么，我们就应该以知识、以科学担起新世纪的重担。
同学们，我们正处于成长发育阶段，学习科学，让我们从小做起。我们要努力学好各种文化课，因为这是一切学习的基础；同时，对各种适合我们小学生看的科普书籍、报刊，最好在课余多阅读一些；还应该积极动手搞各种科学小实验、小制作，写科学小论文等，培养对科学的兴趣。长此下去，我们一定能够热爱科学，拥有丰富的科学知识。 人类的智慧是无限的，无论是美国的挑战者号爆炸，还是全球计算机病毒的升级，从来都不能阻止人类的科技进步。“知识就是力量”，培根这句脍炙人口的格言不知激励了多少渴求知识的人。如今，让我们也用它来勉励自己，做一个热爱科学的新一代，担起新世纪的重任，为我们祖国的明天，谱写出更加辉煌的诗篇！
谢谢大家。
When you look the lovable animated cartoon, plays is in a stew human's computer games, rides the fast train, is answering transoceanic telephone time, ......Not only your might once realize the science the strength, the science changed this world, also changed our life, the science side us.
Opens for the 20th century the grand chapters, not only we discovered the humanity to experience the blood and the fire baptism in these hundred years, has created the innumerable scientific miracles. 19th century France famous science fiction writer of fiction Verne fictionalizing, at that time let the human be inconceivable, he fantasized moon landing travel, the airplane, the long-range gun and so on, all 11 became the reality in the 20th century. In the 21st century today, the high tech is ubiquitous.
As cross-century one generation, how posture should we adapt the new century by, the load get up the new century heavy burden? Not only science and technology changing with each new day, causes the science to serve for the most advanced technique, also more and more many seeps to ring ours daily life, this needs us who is in the young people time to deeply love the science, the study science. Participation science and technology “five small” competition, reading science and technology books, caused me to understand many truths. The precise robot, does not use the fuel the automobile, the hypothesized soccer game, high tech information transmission and so on, each one vivid interesting phenomena, aroused me to explore the science the desire.
Our each people all want to study the science, the dissemination civilization, while enjoys the new life, must create the new life, now, the technical proct renewal speeds up unceasingly, the visible television, the computer surfer, the pacemaker, already did not calculate was fresh. Vacuum cleaner invented which from 1901, to the artificial earth satellite, carried the human spaceship, the science and technology demonstrates the formidable strength in the different domain. Electronic instry, communication technology daily popularization, nanotechnology, superconctivity material widespread application, soon one day, perhaps in yours dinner table, can appear likely bio-engineering foods and so on outer space green pepper, man-made beefsteak. Studies the science and technology, is not merely in order to become the scientist, also is for can adapt the life, more has been able to become the new century the master, the load gets up the new century, is the national construction, makes the contribution for the human culture.
Since new China had been established, our country's technical development progresses by leaps and bounds, the synthesized insulin, finishes a job plants, the hybrid rice again, explodes atomic bomb and hydrogen bomb, launch satellite and airship and so on, these technical achievement which focuses attention on the common people, reced our country and the advanced countries science and technology disparity greatly, has poured into the vigor for our country's modernization. Grandpa Deng Xiaoping said “the science and technology is the first proctive forces”, indeed so, the science has inserted the wing for our motherland soaring. Chairman Mao Zedong once said to the youth that, the world was you, also is we, but is your in the final analysis. This speech, has been full of the elders to our earnest expectation. If the elders have constructed the 20th century motherlands with the instrious work, that, we should by the knowledge, get up the new century heavy burden by the scientific load.
Schoolmates, we are being at the growth developmental stage, the study science, lets us start since childhood. We must learn each kind of literacy class diligently, because this is all study foundation; At the same time, to each kind the popular science books, the publication which suits our elementary student to look, should better read some in the after school; Also should begin to do each science small experiment, the small manufacture positively, writes the science small paper and so on, raises to the science interest. Long this gets down, we can certainly deeply love the science, has the rich scientific knowledge. Humanity's wisdom is infinite, regardless of is US's Challenger number detonation, the whole world computer virus' promotion, always all cannot prevent humanity's advance in technology. “The knowledge is the strength”, Bacon this sentence enjoys great popularity the maxim did not know had driven how many earnestly seeks the knowledge human. Now, lets us also use it to encourage oneself, makes one to deeply love the science the new generation, the load gets up the new century heavy responsibility, for our motherland tomorrow, will compose a more magnificent poem!
Thanks everybody.

科技丰富生活初中英语作文 篇3
The development of modern technology has made peoples life more complexso people should choose to have a simple and easy life without using technology.To what extent do you agree or disagree?
Give reasons for your answer and include relevant examples from your knowledge or experience.
The advancement of modern technology is making peoples life more comfortable and at the same time less human.To those who enjoy the benefits of technologythere is no better time to be alive than nowbut to others life has been increasingly complex and stressful.The issue is whether such new technological machines as computers and the Internet would be our servants forever or eventually could become our masters.
All kinds of inventions made possible by technology are designed to be the slaves of human beingsif human beings are not to be slaved by machines.Once upon a timewe were plain peoplebut that was before we began having relationships with technological systems.By getting involved with computerized machineswe could not help changing the way we live and the way we workfor better or for worse It can be realized that life is more complex because much of modern technology is not born to meet primary human needsand many "unnecessary" inventions are procing negative effects on a living style that used to be relatively simple.Thusthere is an overwhelming feeling of complexity in the sense that machines act like humans and humans act like machines.Now that "intelligent" machines such as robots are widely applied to take the place of human beings because they are capable of doing many useful jobsalthough making many people jobless.Those who cannot work with computers are disadvantaged and therefore helpless while the traditional skills and simple ways of life are fading awaynever to return again.现代科技的发展使人们的生活更加复杂，人们应该选择一种简单而不使用技术的生活，你在多大程度上同意或不同意?
给出你的答案的原因，并从你的知识或经验包括相关的例子。
现代信息技术的发展使人们的生活更舒适，同时减少人力。对那些喜欢技术的好处，有没有更好的时间比现在还活着，但是别人的生活已经越来越复杂和紧张。问题是，电脑和互联网这样的新技术设备将我们的仆人永远或最终能成为我们的主人。
各种各样的发明成为可能的技术设计是人类的奴隶，如果人类不被奴役的机器，曾几何时，我们是普通人，但那是在我们开始有技术系统之间的关系。通过参与计算机的机器，我们不能改变我们的我们的工作和生活方式，或好或坏的可以实现的，生活是更复杂的因为许多现代科技并不是生来要满足主人的需要，许多“不必要”的发明是产生在生活方式使用的是相对简单的负面影响。因此，这是一种无法抗拒的复杂的感觉，机器像人类的感觉像马中国现在的“智能”的机器如机器人，是因为他们有能力做了许多有益的工作，广泛应用于取代人类，虽然使许多人失业。那些不能用电脑工作都处于弱势，因此无奈而传统技能和简单的生活方式都消失了，再也回不来了再次。

㈥ 科技英语阅读4The invention of the incandescent (白炽的) light bulb by
a,b,b,c,d,1,科技英语阅读4
The invention of the incandescent (白炽的) light bulb by Thomas Edison in 1879 created a demand for a cheap,readily available (可利用的) fuel with which to generate large amounts of electric power.Coal seemed to fit the bill,and it fueled (供以燃料) the earliest power stations (which were set up at the end of the nineteenth century by Edison himself).As more power plants (发电物枣厂) were constructed throughout the country,the reliance (依靠) on coal increased.Since the First World War,coal-fired power plants have accounted for about half of the electricity proced in the United States each year.In 1986 such plants had a bined capacity (产量) of 289 000 megawatts and consumed (消耗散陵) 83 percent of the nearly 900 million tons of coal mined in the country that year.Given (考虑到冲蚂戚) the uncertainty in the future growth of nuclear power and in the supply of oil and natural gas,coal-fired power plants could well provide up to 70 percent of the electric power in the United States by the end of the century.
Yet,in spite of the face that coal has long been a source of electricity and may remain one for many years (coal represents about 80 percent of the United States fossil-fuel reserves,it has actually never been the most desirable fossil fuel for power plants.Coal contains less energy per unit of weight than natural gas or oil; it is difficult to transport,and it is associated with a host of environmental issues among them acid rain.Since the late 1960s problems of emission (散发) control and waste disposal have sharply reced the appeal of coal-fired power plants.The cost of ameliorating (改进) these environmental problems,along with the rising cost of building a facility (设备) as large and plex as a coal-fired power plant,has also made such plants less attractive from a purely economic perspective (观点).
Changes in the technological base of coal-fired power plants could restore (恢复) their attractiveness,however.Whereas some of these changes are evolutionary (进化的) and are intended mainly to increase the proctivity of existing plants,pletely new technologies for burning coal cleanly are also being developed.
31.What is the main idea of the passage?
a.Coal-fired plants are an important source of electricity in the United States and are likely to remain so.
b.Generating electricity from coal is paratively recent in the United States.
c.Coal is a more economical fuel than either oil or nuclear power.
d.Coal is a safer and more dependable fossil fuel than oil or gas.
32.Edison’s electric light bulb is mentioned in the passage because it .
a.replaced gas as a light source
b.increased the need for electrical power
c.was safer than any other method of lighting
d.could work only with electricity generated from coal
33.It can be inferred from the passage that coal became the principal source (主要的来源) of electricity in the United States because it .
a.required no plicated machinery (复杂的机械)
b.was paratively (相对的)plentiful and inexpensive
c.was easy to transport
d.burned efficiently
34.In the author’s opinion,the importance of coal-generated electricity could increase in the future for which of the following reasons?
a.The possible substitutes (代替物) are too dangerous.
b.The cost of changing to other fuels is uncertain
c.The future availability (可用性) of other fuels is uncertain.
d.Other fuels present too manyenvironmental problems.
35.According to the passage,which of the following is one of the goals of the new technology in coal-fired plants?
a.To adapt (使适应) ,the plants to other kinds of fuel.
b.To rece the cost of building more plants.
c.To lengthen the lives of plants already in use.
d.To make the plants already in use more proctive.
㈦ 如何培养学生英语科技文阅读能力
培养学生英语科技文阅读能力：
1．词汇表“八到”记忆法
这是中学生使用最多的方法之一，即将生词表和人的器官相结合：眼里看到、心里想到、手里写到、嘴里拿到、耳朵听到、（结合实物还可以）鼻子嗅到、舌头尝到、手指触到。学生在记忆时不要偷懒，一定要边记边比划，把各个器官充分调动起来。这种方法使学生把目标词汇与自己的大脑神经联系，易记忆深刻，印象持久。
2．分类记忆法
即分析单词的形态，将所要记得单词根据其义、形、音进行分类。例如，按音标的拼读规则记忆单词，按词性变化记忆单词，按同音记忆单词，教师还可教给学生关于英语词根和词缀的知识等；通过词根加前缀或后缀可派生出新的单词，将两个或更多的词放在一起，可合成新的单词。
3．联想记忆法
苏联著名心理学家巴甫洛夫指出：“记忆要依靠联想，而联想则是新旧正式建立联系的产物。”美国心理学家威廉·詹姆士也说：“记忆的秘诀就是根据我们想记住的各种材料来进行各种各样的联想，而这些联想就成了各种资料的钓钩，万一资料沉没脑海，我们就可以通过联想这样的钓钩将资料钩出来。”充分运用发散思维展开自己的想象力，使所要记忆的英语单词，生动、形象和具体化，使生词与熟词之间建立一种联系，从而达到以旧带新，快速记忆的目的。

Some scientists say that animals in the ocean are increasingly threatened(威胁)by noise pollution caused by human beings..
The noise that affects（影响） sea creatures comes from a number of human activities. It is caused mainly by instrial underwater explosions（爆炸）, ocean drilling, and ship engines. Such noises are added to natural sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分贝 measured in water are different those measure on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibels level of one hundred and ninety-five would have the same effect.
Some scientists have proposed（提议）setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales（鲸鱼）.
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals. The research team found that powerful underwater explosion were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosion had caused their ears to bleed（流血）and become infected（感染）.
Many researchers whose work depends on ocean sounds object to(反对) to a limit of one hundred and twenty decibels. They say such a limit would mean an end to important instrial and scientific research.

根据生物某些特征的存在来确定其它因素的现象，叫生物的指示现象，或指示作用。它们具有指示意义的某些特征，称为指示特征(包括形态的、生理的、生物化学的等)。有气候指示特征的(如热带植物、寒带植物)；有水指示现象的(人们在干旱地区常借助植物来找水源)；有土壤指示现象的(铁芒箕是强酸性土壤的指示植物，碱蓬指示碱性土壤)；有地质指示现象的(湖北省黄石市就有一种草能指示地下有铜和铁矿)；还有些植物对环境污染有指示作用，如矮牵牛花。 生物的指示作用表明，各个自然地理要素之间处于紧密相互联系、相互依赖的关系之中。掌握了它们之间有规律的联系，就有可能利用一个要素的特征去认识另一个要素的存在。 从理论上讲，地球上最初产生地壳，之后形成大气圈、水圈，最后出现植被、土壤和动物界。因而，愈是年老的(即先产生的)要素对其它年青的(即后产生的)要素影响愈大；愈是年青的的要素对其它年老的要素依赖性愈大。正是这些独立性最小而依赖性最大的要素具有最大指示意义。所以，后出现的植物对其它要素的影响具有很大的表现能力。 地球上的生命界可以划分成不同的层次或组织水平。从大分子有机物开始直到生物圈，复杂程度逐级增加。当从一个层次过渡到另一个较高层次时，生命组织便会出现前一级所不具有的新性质和特征。 生物存在于地理环境之中的，它们在个体发育的全部过程中，经常不断地与环境间进行着物质与能量的交换。它从环境中取得必需的能源和营养物质，建造自己的躯体，同时又把不需要的代谢产物排放到外界环境中，以此维持其正常的生命活动和种族的繁续。因此，任何生物有机体都不能脱离环境而生存。环境控制和塑造着生物的生理过程、形态构造和地理分布。 在环境对生物发生影响的同时，生物有机体，特别是它们的群体也对环境产生相当明显的改造作用。针叶林下土壤的酸度往往比同一地区阔叶林下的要高些。湖泊中浮游生物大量繁殖时，导致水体透明度下降，从而改变水中的光照条件。从更长远的时间尺度看，生物还参与岩石的风化，地形的改变和土壤的形成，以及某些岩石和矿床的建造。水土流失可以用植物来防治，流动的沙丘可以用乔木、灌木和草本植物来固定。 在环境中对生物的生命活动起直接作用的那些环境要素叫做生态因素，如日光、热、水、风、矿物盐类和其他生物等。地形、海拔高度等则属于间接起作用的因素，它们通过改变气候、土壤等条件而对生物产生影响。 各个生态因素并不是孤立地、单独地对生物发生作用，而是共同综合在一起对生物产生影响，一个生态因素不管它对生物的生存有多么重要，也只能在有其他因素的适当配合下才能发挥其作用。 生物或其群体具体居住地段的所有生态因素的总体叫做生境。由于地表各地气候、土壤、岩性和地形等条件不同，形成极其多种多样的生境类型，这正是地球上生物种类和其群体类型复杂多变的主要原因之一。 地球上各种生态因素的变动幅度非常广阔，每种生物所能适应的范围却有一定的限度。如果当一个或几个生态因素的量或质低于或高于生物所能忍受的临界限时，不管其他因素是否适合，生物的生长发育和繁殖都会受到影响，甚至引起死亡。这样的生态因素称作限制因素，它是最易阻挠和限制生物生存的因素。限制因素随时间地点而变，也因生物种类而异。在干旱和半干旱地区，水分条件往往是植物生存的限制因素。在严重污染的水域中，有毒的污染物常常是水生生物生存的限制因素。在研究环境对生物的生态作用时，既要注意生态因素的综合作用，又要找出在一定条件下影响生物生存的限制因素，为采取相应管理措施提供科学依据。 生物在其生存过程中，对生态因素的忍耐不仅有一个生态上限和下限，同时在它的耐性限度内还有一个比较小的生态上的最适范围，在这里生物生长发育得最好。在自然界，生物种并非经常处于其最适生境条件下，因为生物间的相互作用和外界自然条件的变化，妨碍生物去利用最适宜的环境。不同的生物种对生态因素和环境的适应能力有差异。一般来说，对环境适应能力较强种类，其分布范围较广。
