　　科學(xué)技術(shù)英語作文篇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.

　　"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, thats wrong. Thats 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 its never been successful.

　　AK: "Because we dont really know what message were 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, theres 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.

　　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.

　　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.

　　Buckyball Traps Single Water Molecule

　　The carbon molecule known as a buckyball, a member of the fullerene family, can act as a cage for a variety of other chemicals. And now researchers have used one to trap a single molecule of water. The work appears in the journal Science.

　　[Kei Kurotobi and Yasujiro Murata, A Single Molecule of Water Encapsulated in Fullerene C60]

　　Placing a molecule that's essential to life within a spherically symmetrical one could let researchers learn more about each.

　　Water molecules stick together, because they carry a slight charge on each end. As the positive pole of one H2O attracts the negative pole of another, the molecules cling tightly together. You can't separate a single water molecule from its fellows with a tiny pair of tweezers, so isolating it in a carbon cage may reveal new secrets about the intrinsic nature of a lone H2O.

　　What about the cage itself? Researchers already know that buckyballs refuse to dissolve in water, sometimes even floating like miniature beach balls. But what happens when the water is within? Putting polar molecules inside buckyballs may influence the chemical behavior of their outsides, and create new molecules with unique properties. Not to mention making our understanding even…fuller.

　　Many years ago, when scientists tried to make a robot to do some human work, they could never thought about how far the robot could go. Today, some scientists even predict that the wisdom of robot will surpass human being and take place of us. In the science fiction movies, the directors have explored the consciousness of intelligent machines, who showed how these machines controlled people at last. The directors warned people that they may lose the dominant position in the future. Recently, a robot was given the citizenship and it became the first robot to be treated as human being. The public was shocked, but when they saw the robot could communicate with human beings and question about matters, they felt scared. Maybe in the future, the robot will replace us in many aspects.

　　Today, with the fast development of science and technology, the artificial intelligence has gone much further than people can imagine, such as the robot. Now the first robot is admitted to be a citizen, which scares so many people. Many scientists had predicted that someday robots would replace human being not only in physical work, but also in minds. How terrible it would be. It is said that scientists saw two robots discussing by creating a new language, then they decided to turn down the machine and made them stop working. They knew clearly the danger may happen in the future. Most people have thought about self-consciousness that robot may have some day, but scientists still have a lot of passion in searching the robots. They want to complete everything. But no one can make sure what they can bring for human being.
