㈡ 中學生英語關於科技的演講稿 急求
同學們:
當你們看著可愛的動畫片,玩著迷人的電腦游戲,坐上快速的列車,接聽著越洋電話的時候,……你可曾意識到科學的力量,科學不僅改變了這個世界,也改變了我們的生活,科學就在我們身邊。
翻開20世紀的壯麗篇章,我們發現人類在這百年中不僅經歷了血與火的洗禮,更創造了無數科學奇跡。19世紀法國著名科幻小說家凡爾納的虛構,當時讓人不可思議,他所幻想的登月旅行、飛機、遠射程炮等,在20世紀都一一成為現實。在21世紀的今天,高科技更是無處不在。
作為跨世紀的一代,我們又該以怎樣的姿態去適應新世紀,擔起新世紀的重擔呢? 科學技術的日新月異,使得科學不只為尖端技術服務,也越來越多地滲透到我們的日常生活之中,這就需要正處於青少年時代的我們熱愛科學,學習科學。參加科技「五小」比賽、閱讀科技書籍,使我明白了許多道理。精密的機器人,不用燃料的汽車,虛擬的足球賽,高科技信息的傳送等等,一個個生動有趣的現象,激起了我探索科學的願望。
我們每個人都要學習科學,傳播文明,在享受新生活的同時,更要創造新生活,如今,科技產品的更新換代不斷加快,可視電視、電腦上網、心臟起搏器,已經不算新鮮了。從1901年發明的真空吸塵器,到人造地球衛星、載人宇宙飛船,科技在不同領域里顯示出了強大的力量。電子產業、通訊技術的日益普及,納米技術、超導材料的廣泛應用,不久的一天,也許就在你的餐桌上,會出現像太空青椒、人造牛排等生物工程食品。學習科學技術,不僅僅是為了成為科學家,也是為了能適應生活,更為了能成為新世紀的主人,擔起新世紀,為國家建設,為人類文明做出貢獻。
新中國成立以來,我國的科技發展突飛猛進,人工合成胰島素、斷手再植、雜交水稻、爆炸原子彈和氫彈、發射人造衛星和飛船等等,這些令世人矚目的科技成就,大大縮短了我國和先進國家的科學技術的差距,為我國的現代化建設注入了活力。鄧小平爺爺說「科學技術是第一生產力」,的確如此,科學為我們祖國的騰飛插上了翅膀。毛澤東主席曾對青年說,世界是你們的,也是我們的,但歸根結底是你們的。這句話,飽含了長輩們對我們的殷切期望。如果說長輩們用辛勤的勞動建設了20世紀的祖國,那麼,我們就應該以知識、以科學擔起新世紀的重擔。
同學們,我們正處於成長發育階段,學習科學,讓我們從小做起。我們要努力學好各種文化課,因為這是一切學習的基礎;同時,對各種適合我們小學生看的科普書籍、報刊,最好在課余多閱讀一些;還應該積極動手搞各種科學小實驗、小製作,寫科學小論文等,培養對科學的興趣。長此下去,我們一定能夠熱愛科學,擁有豐富的科學知識。 人類的智慧是無限的,無論是美國的挑戰者號爆炸,還是全球計算機病毒的升級,從來都不能阻止人類的科技進步。「知識就是力量」,培根這句膾炙人口的格言不知激勵了多少渴求知識的人。如今,讓我們也用它來勉勵自己,做一個熱愛科學的新一代,擔起新世紀的重任,為我們祖國的明天,譜寫出更加輝煌的詩篇!
謝謝大家。
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.

科技豐富生活初中英語作文 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.現代科技的發展使人們的生活更加復雜,人們應該選擇一種簡單而不使用技術的生活,你在多大程度上同意或不同意?
給出你的答案的原因,並從你的知識或經驗包括相關的例子。
現代信息技術的發展使人們的生活更舒適,同時減少人力。對那些喜歡技術的好處,有沒有更好的時間比現在還活著,但是別人的生活已經越來越復雜和緊張。問題是,電腦和互聯網這樣的新技術設備將我們的僕人永遠或最終能成為我們的主人。
各種各樣的發明成為可能的技術設計是人類的奴隸,如果人類不被奴役的機器,曾幾何時,我們是普通人,但那是在我們開始有技術系統之間的關系。通過參與計算機的機器,我們不能改變我們的我們的工作和生活方式,或好或壞的可以實現的,生活是更復雜的因為許多現代科技並不是生來要滿足主人的需要,許多「不必要」的發明是產生在生活方式使用的是相對簡單的負面影響。因此,這是一種無法抗拒的復雜的感覺,機器像人類的感覺像馬中國現在的「智能」的機器如機器人,是因為他們有能力做了許多有益的工作,廣泛應用於取代人類,雖然使許多人失業。那些不能用電腦工作都處於弱勢,因此無奈而傳統技能和簡單的生活方式都消失了,再也回不來了再次。
㈤ 科技英語閱讀7內容太長了 到8里接著看吧
【1節】有兩個主要的事情,使飛機工程困難;必須盡一切組成部分可靠的,可能和需要建立的一切輕如可能。事實上,飛機是在空中,不能停止,如果任何事情都會發生錯誤,這使得或許是生死存亡,其性能絕對可靠。鑒於某些權力的發動機,因此,一定燃料消耗,有一個實際的限制,總重量的飛機可以飛。在體重盡可能通緝燃料,無線電導航儀器,乘客座位,或貨物的房間,當然,乘客或貨物本身。因此,結構的飛機將作為體積小,重量輕的安全性和效率將允許。設計者必須計算出的正常負荷,每個部分將難以承受。這個專家稱為''強調人' 。他考慮到任何不尋常的強調,可能是把一部分作為一個防範錯誤的製造,意外損壞等。男子應力的計算去設計的一部分,他必須一樣強烈的應力男子說,如果必要的。一個或兩個樣品的測試總是證明他們是強烈的設計意圖。每個單獨的部分進行測試,然後整個裝配,例如,一個完整的機翼,並最終整個飛機。當一種新型的飛機正在取得,通常只有一個頭三個提出將飛行。兩名將被摧毀在地面上的結構試驗。第三是將測試空氣中。【2節】兩種地面強度試驗進行。首先是尋找抗負荷的翅膀,尾巴等直至他們達到其最大負荷和崩潰。其他測試是疲勞強度。相對較小的載荷應用數千次。每個可以及在什麼樣的結構可以作為一個單一的負荷,但許多重復可能導致崩潰。一位從這個試驗是這樣做的客艙。這是充滿空氣在高壓力,高超低空飛行,完全淹沒在一個大罐的水,而測試正在進行中。周圍的水無法從機艙爆裂像一個炸彈,如果有一個失敗。當飛機已通過所有的測試可以得到政府的單機適航證,沒有這一點,是非法的飛行,除了飛行試驗。製作可靠的工作部件是困難的,因為決策的結構足夠強大。飛行控制,電氣設備,防火措施等。不僅必須重量輕,而且必須在高海拔地方的溫度可能低於冰點和熱空氣的一個機場在熱帶地區。【翻譯的還不錯吧!】
㈥ 科技英語閱讀4The invention of the incandescent (白熾的) light bulb by
a,b,b,c,d,1,科技英語閱讀4
The invention of the incandescent (白熾的) 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 (發電物棗廠) 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 (產量) 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 (考慮到沖螞戚) 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 (散發) control and waste disposal have sharply reced the appeal of coal-fired power plants.The cost of ameliorating (改進) these environmental problems,along with the rising cost of building a facility (設備) as large and plex as a coal-fired power plant,has also made such plants less attractive from a purely economic perspective (觀點).
Changes in the technological base of coal-fired power plants could restore (恢復) their attractiveness,however.Whereas some of these changes are evolutionary (進化的) 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 (主要的來源) of electricity in the United States because it .
a.required no plicated machinery (復雜的機械)
b.was paratively (相對的)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 (使適應) ,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 如何培養學生英語科技文閱讀能力
培養學生英語科技文閱讀能力:
1.詞彙表「八到」記憶法
這是中學生使用最多的方法之一,即將生詞表和人的器官相結合:眼裡看到、心裡想到、手裡寫到、嘴裡拿到、耳朵聽到、(結合實物還可以)鼻子嗅到、舌頭嘗到、手指觸到。學生在記憶時不要偷懶,一定要邊記邊比劃,把各個器官充分調動起來。這種方法使學生把目標詞彙與自己的大腦神經聯系,易記憶深刻,印象持久。
2.分類記憶法
即分析單詞的形態,將所要記得單詞根據其義、形、音進行分類。例如,按音標的拼讀規則記憶單詞,按詞性變化記憶單詞,按同音記憶單詞,教師還可教給學生關於英語詞根和詞綴的知識等;通過詞根加前綴或後綴可派生出新的單詞,將兩個或更多的詞放在一起,可合成新的單詞。
3.聯想記憶法
蘇聯著名心理學家巴甫洛夫指出:「記憶要依靠聯想,而聯想則是新舊正式建立聯系的產物。」美國心理學家威廉·詹姆士也說:「記憶的秘訣就是根據我們想記住的各種材料來進行各種各樣的聯想,而這些聯想就成了各種資料的釣鉤,萬一資料沉沒腦海,我們就可以通過聯想這樣的釣鉤將資料鉤出來。」充分運用發散思維展開自己的想像力,使所要記憶的英語單詞,生動、形象和具體化,使生詞與熟詞之間建立一種聯系,從而達到以舊帶新,快速記憶的目的。

根據生物某些特徵的存在來確定其它因素的現象,叫生物的指示現象,或指示作用。它們具有指示意義的某些特徵,稱為指示特徵(包括形態的、生理的、生物化學的等)。有氣候指示特徵的(如熱帶植物、寒帶植物);有水指示現象的(人們在乾旱地區常藉助植物來找水源);有土壤指示現象的(鐵芒箕是強酸性土壤的指示植物,鹼蓬指示鹼性土壤);有地質指示現象的(湖北省黃石市就有一種草能指示地下有銅和鐵礦);還有些植物對環境污染有指示作用,如矮牽牛花。 生物的指示作用表明,各個自然地理要素之間處於緊密相互聯系、相互依賴的關系之中。掌握了它們之間有規律的聯系,就有可能利用一個要素的特徵去認識另一個要素的存在。 從理論上講,地球上最初產生地殼,之後形成大氣圈、水圈,最後出現植被、土壤和動物界。因而,愈是年老的(即先產生的)要素對其它年青的(即後產生的)要素影響愈大;愈是年青的的要素對其它年老的要素依賴性愈大。正是這些獨立性最小而依賴性最大的要素具有最大指示意義。所以,後出現的植物對其它要素的影響具有很大的表現能力。 地球上的生命界可以劃分成不同的層次或組織水平。從大分子有機物開始直到生物圈,復雜程度逐級增加。當從一個層次過渡到另一個較高層次時,生命組織便會出現前一級所不具有的新性質和特徵。 生物存在於地理環境之中的,它們在個體發育的全部過程中,經常不斷地與環境間進行著物質與能量的交換。它從環境中取得必需的能源和營養物質,建造自己的軀體,同時又把不需要的代謝產物排放到外界環境中,以此維持其正常的生命活動和種族的繁續。因此,任何生物有機體都不能脫離環境而生存。環境控制和塑造著生物的生理過程、形態構造和地理分布。 在環境對生物發生影響的同時,生物有機體,特別是它們的群體也對環境產生相當明顯的改造作用。針葉林下土壤的酸度往往比同一地區闊葉林下的要高些。湖泊中浮游生物大量繁殖時,導致水體透明度下降,從而改變水中的光照條件。從更長遠的時間尺度看,生物還參與岩石的風化,地形的改變和土壤的形成,以及某些岩石和礦床的建造。水土流失可以用植物來防治,流動的沙丘可以用喬木、灌木和草本植物來固定。 在環境中對生物的生命活動起直接作用的那些環境要素叫做生態因素,如日光、熱、水、風、礦物鹽類和其他生物等。地形、海拔高度等則屬於間接起作用的因素,它們通過改變氣候、土壤等條件而對生物產生影響。 各個生態因素並不是孤立地、單獨地對生物發生作用,而是共同綜合在一起對生物產生影響,一個生態因素不管它對生物的生存有多麼重要,也只能在有其他因素的適當配合下才能發揮其作用。 生物或其群體具體居住地段的所有生態因素的總體叫做生境。由於地表各地氣候、土壤、岩性和地形等條件不同,形成極其多種多樣的生境類型,這正是地球上生物種類和其群體類型復雜多變的主要原因之一。 地球上各種生態因素的變動幅度非常廣闊,每種生物所能適應的范圍卻有一定的限度。如果當一個或幾個生態因素的量或質低於或高於生物所能忍受的臨界限時,不管其他因素是否適合,生物的生長發育和繁殖都會受到影響,甚至引起死亡。這樣的生態因素稱作限制因素,它是最易阻撓和限制生物生存的因素。限制因素隨時間地點而變,也因生物種類而異。在乾旱和半乾旱地區,水分條件往往是植物生存的限制因素。在嚴重污染的水域中,有毒的污染物常常是水生生物生存的限制因素。在研究環境對生物的生態作用時,既要注意生態因素的綜合作用,又要找出在一定條件下影響生物生存的限制因素,為採取相應管理措施提供科學依據。 生物在其生存過程中,對生態因素的忍耐不僅有一個生態上限和下限,同時在它的耐性限度內還有一個比較小的生態上的最適范圍,在這里生物生長發育得最好。在自然界,生物種並非經常處於其最適生境條件下,因為生物間的相互作用和外界自然條件的變化,妨礙生物去利用最適宜的環境。不同的生物種對生態因素和環境的適應能力有差異。一般來說,對環境適應能力較強種類,其分布范圍較廣。
