篇1：中国近代科学技术落后的原因与未来科学技术发展展望

中国近代科学技术落后的原因与未来科学技术发展展望

中国是古代世界科学活动中心,然而,近现代世界科学活动的中心转移到了西方国家,中国近代科学技术落后了,笔者认为资本主义生产对科技的需求促进了科技的发展,而在中国漫长的封建社会缺乏这种需求,这是中国近代科技落后的外因;中国古代科技体系结构不合理,科技长期处于经验层次,重视实用技术,轻视理论的`提升,这是中国近代科技落后的内因.展望未来,世界科学活动中心能否再次转移到中国.

篇2：中国近代科学技术落后原因分析

中国近代科学技术落后原因分析

近代,长期领先于世界的中国科学技术却落伍了.造成近代中国科学技术落后的原因主要有以下几点:一是超稳定的封建专制统治对思想的钳制严重阻碍了科学技术的`发展;二是根深蒂固的小农经济和近代资本主义难产是导致我国近代科学技术落后的根本原因;三是中国传统文化的基本特征及其固有缺陷不利于产生近代科学技术;四是近代落后的教育与继续推行的科举制度使科技人才空前缺乏,严重地阻碍了近代科学技术的发展.

篇4：科学技术发展英语作文

科学技术发展英语作文

“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.
