科学技术英语作文 篇1
"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.

科学技术英语作文 篇3
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.

directions: you are allowed 30 minutes to write a composition on the topic science and technology。 you should write at least 120 words and base your composition on the following instructions。
1。 science and technology play an important role in modern。
2。 science and technology are not always a positive force in modern life。
science and technology
science and technology play an important role in people's daily lives。 if you compare the life of people today with that in the past， it is easy to see that science and technology have done a great deal to improve the quality of people's lives。 for example， computers have become our good friends: with the help of computers， people all over the world are able to share whatever information on the net， which shortens the distance between them。 with the invention of radio and tv， people now can stay at home to get themselves informed about both domestic and international news。
but as a coin has two sides， technology can aisc have an negative influence upon people's lives。 now technology crimes are very common。 what's more， the nuclear bomb threatens our human existence。 so i think we must pay enough attention to the misuse of technology。
in spite of its disadvantages， we should admit that technology is very useful， without science and technology， man's life would not be as convenient as today。
