科學技術英語作文1

  human life can not continue without science and technology. for many years, human society has developed with the advance of science and technology while the development of science and technology has in turn brought the process to mankind. so the life we are living now is more civilized than that of our fore fathers.

  the development of science and technology have brought about many changes in peoples life. for eample, the invention of television and space rocket have opened a new era for mankind. through the use of tv people can hear the sound and learn the events happening thousands of miles away. owing to the invention of spaceship and rocket, the dream of mans landing on the moon has now come true.

  science and technology also play an important role in our socialist construction. we may say, our socialist construction is just like a skyscraper, while science and technology are its base. without the base, the skyscraper cant be built. therefore, we should try our best to contribute to the development of science and technology so as to provide a more solid base to build our country.

科學技術英語作文2

  "She has this thing where she goes to a movie theater, watching a horror movie and there was a wolf howling in the background.” University of Cambridge zoologist Arik Kershenbaum, talking about his collaborator Holly Root-Gutteridge, a biologist at Syracuse University. She said to herself, ‘Well, that's wrong. That's clearly a European wolf and not a North American wolf like it should be in the scene.'"

  Slight variations in the way we speak allow us to tell whether someone is from Boston or New York just by listening to them. The same turns out to be true for the animals known as canids, which includes wolves, dogs and coyotes. They all howl to communicate—but those howls vary. Canids can tell which howls belong to their known associates and which belong to strangers.

  So Kershenbaum and Root-Gutteridge decided to categorize the howls of different canids around the world. Together with colleagues, they compiled recordings of more than 2,000 canid howls, including European wolves, Mexican wolves, arctic wolves, dingoes, coyotes, golden jackals, domestic dogs, New Guinea singing dogs, and more. A computer program sorted the howls into different types. The study was published in the journal Behavioral Processes. [Arik Kershenbaum et al, Disentangling canid howls across multiple species and subspecies: Structure in a complex communication channel]

  Based on the analysis, canids use 21 different kinds of howls to communicate. If you think of the howls as words, then all canids have the same vocabulary—but each species or sub-species has its own unique dialect. Some words are more common in one dialect, while other words are more common in another dialect and so on. By matching dialect with species and geography, researchers could monitor endangered species, like red wolves, just by listening.

  AK: "Being able to distinguish between the howls of a coyote and the howls of a red wolf opens the possibility for techniques of passive monitoring, passive population monitoring, using acoustics."

  Meanwhile, ranchers have tried to broadcast specific howls to discourage grey wolves from feasting on their livestock, but it's never been successful.

  AK: "Because we don't really know what message we're conveying to the wolves when we play back an arbitrary howl. For all we know, we could be playing back a howl that means come and eat, there's lots of interesting food over here."

  The research could thus finally bring peace to the conflict between ranchers and wolves, by finally speaking to the predators in their own language.

  —Jason G. Goldman

  The Popular Science Knowledge and Science Technology

  科普知識與科學技術

  歷有很多發明,起著很重要的'作用,其中一些改變了世界。依你之見,什么是最重要的發明,并說明原因,也就是它起的作用(不少于三點)。80詞左右。

  The Most Helpful Invention

  There are a lot of inventions in the history. Some of them play an important role in people’s life and some have greatly changed the world.

  In my opinion, I think the most important invention is the car. First, people used to travel by train or by plane. But now, they can go any place by car. Second, when holiday comes, they can visit their family and friends by car. Third, they can also go to many places of interest to enjoy themselves.

  In a word, I do agree that cars are the most important invention.

  Directions: For this part, you are allowed thirty minutes to write a composition on the topic We Need to Broaden Our Knowledge. You should write no less than 120 words and you should base your composition on the outline (given in Chinese) below:

  1、科學技術是社會發展所不可缺少的

  2、社會科學和自然科學相互滲透

  3、現代大學生需要廣博的知識

  We Need to Broaden Our Knowledge

  Knowledge is power, especially scientific and technological knowledge. Science and technology are the motive power of the social development. Without them human society could never have developed from primitive society to modern society. Therefore, to conquer and transform nature, we must master scientific knowledge.

  However, social knowledge is also essential. Without it we can not understand society and don't know the law of the social development. As a result we are unable to tovern society. Therefore, besides scientific knowledge we need to master social science, philosophy, politics, history, aesthetics, etc, so that we can know society from all perspectives and form a correct world outlook.

  To meet new challenges in he 21st century, we university students should lose no time to acquire as much knowledge as possible so that we will become qualified successors of the socialist cause.

  我們需要拓寬知識面

  知識就是力量,尤其是科技知識。科學技術是社會發展的動力。沒有它們,人類社會永遠不可能從原始社會發展到現代社會。因此,要征服和改造自然,就必須掌握科學知識。

  然而,社會知識也是必不可少的。沒有它,我們就無法了解社會,也無法了解社會發展的規律。因此,我們無法支配社會。因此,除了科學知識,我們還需要掌握社會科學、哲學、政治、歷史、美學等,這樣我們才能從各個角度認識社會,形成正確的世界觀。

  迎接21世紀新的'挑戰,我們大學生應該抓緊時間學習盡可能多的知識,成為社會主義事業的合格接班人。

  【參考譯文】

  歷史上有許多發明。他們中的一些人在人們的生活中起著重要的作用,有些人改變了世界。

  在我看來,我認為最重要的`發明是汽車。首先,人們過去乘火車或飛機旅行。但現在,他們可以去任何地方的汽車。第二,當假期來臨時,他們可以開車去拜訪家人和朋友。第三,他們也可以去許多有趣的地方享受自己。

  總之,我同意汽車是最重要的發明。

科學技術英語作文10

  here is a difference between science and technology Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools,techniques, and procedures for implementing the findings of science Progress in science excludes the human factor What scientists discover may shock or anger people--as did Darwin's theory of evolution Unlike science, progress in technology must be our slave and not the reverse.

  We are all familiar with the abuses of technology That promise is a cleaner and healthier worldScience的差異是一種回答理論問題的方法,技術是解決實際問題的方法。必須做科學與發現的事實和觀察的現象之間的關系,性質和與建立理論,為組織這些事實和關系;技術必須與工具,技術,以及執行結果的科學程序。

  另一種科學和技術之間的區別是關乎每個進展。科學進步排除人為因素。科學家,誰試圖理解宇宙和認識與把握的準確性和程度最高的真理,不能留意自己或其他人的喜歡或不喜歡,或對事物的健身流行的想法。科學家們發現,可能觸電或憤怒的人-象達爾文的進化論。但是,即使一個令人不快的真相更可能是有用的,而我們有拒絕相信的選擇!但是,很難如此技術,我們沒有拒絕聽到爆音所產生的超音速飛機飛行的開銷,我們沒有拒絕呼吸污染的空氣期權。與科學技術的進步必須成為我們的.奴隸,而不是相反。該技術的合法的目的是為了peopie -一般人,而不僅僅是一些人,和后代,而不僅僅是那些目前誰希望獲得自己的優勢。

  我們都熟悉技術的濫用。許多人指責技術日益嚴重的污染,資源枯竭,甚至在一般的社會腐敗本身-以至于技術的承諾是模糊了。這個承諾是一個更清潔,更健康的世界。如果明智的科學和技術的應用不會導致一個更美好的世界,還有什么會?
