我们要学科学、爱科学,把科学展示出来。但怎样才能做到呢?科学家告诉我们,好奇心是人的天性中最重要的方面之一,也是激发探索科学奥妙的主要动机;而最能满足这种强烈欲望的方法是要勇于问为什么,勇于尝试、创新,勇于推翻前人的话、结论,而最终得到的就是自己的成果。例如,伽利略,哥白尼等人,他们不顾来自各方面的压力和反对,勇敢地指出前人错误的论点。通过亲身实践,做实验,证明了自己的观点是正确的,换来的是自己的成功。
一般人在对“科学”这个词的理解,可能理解为“人类已经找到的代表现实的真理知识内容”(具体的科学知识)或“科学真理的理论”(科学理论体系),也可能是“如何找到并区别称为科学知识及科学理论的方法”(科学方法和科学精神),在后者中,可能也包含科学哲学。事实上,科学的存在和发展中一个永恒的问题是标准与创新的矛盾。一方面,科学知识的出现必然形成相关的评判正误的标准,另一方面,科学知识出现的过程就是对原有标准突破过程,因此也必然受到原有标准的限制或压制。
四年级 一个有趣发现作文、手抄报样式 跪求,急需!!!
竹山县政府办消息[网络通讯员 陈太平]近日,在竹山县黄龙滩库区居住20多年的楼台乡农民陈同庆喜迁新居后,正忙着给嫁接的冬枣除草、施肥。与他一样,该县黄龙滩库区千余移民迁出库区,靠发展绿色产业闯富路。
黄龙滩水库始建于上世纪七十年代,因库区生态环境恶劣,地质滑坡垮塌严重,库区移民缺乏基本的生存和发展空间。为缓解黄龙滩库区移民对生态环境的压力,该县在鲍竹路等公路沿线新建移民小区,并补助600多万元扶持他们易地搬迁建房。
竹山近6万农户散居在山区,其中部分农户分布在库区、自然保护区或偏远的高山地带。由于农村群众传统的耕作方式和落后的生活方式的影响,对当地的生态环境造成极大破坏,导致森林植被减少,水土大量流失,水质受到污染。为此,该县确立了实施生态移民工程,将分布在库区、自然保护区和偏远山区的农户逐步迁出,从根本上解决生态退化和农民生活贫困两难的矛盾。
为保护迁出地的生态环境,该县出台生态移民奖励政策,鼓励农民异地搬迁。柳林乡地处堵河源自然保护区,是国家南水北调中线工程的重要水源区。该乡从去年起每年举行一次生态保护大会,并从财政收入中拿出10万元设立生态移民奖励基金,鼓励农民迁出保护区。目前,位于堵河源核心保护区的民主、墨池和龙石坪等4个村18户农民先后下山定居。
这些需要搬迁的农户大多数家庭贫困,为此该县把生态移民与扶贫开发、移民新村建设与新农村建设有机结合,整合资源扶持移民发展绿色产业、建设生态经济庭院,确保移民迁得出、稳得住、能发展。圣水茶场在该县秦古镇大观山茶叶基地建起两座花园式小区,无偿提供给得胜、大庙等乡镇偏远山区迁来的32户移民居住。此外,茶场还为移民扶持种苗和化肥,并将1200亩茶园以承包种植的方式分散给农户经营。移民高瑞聪种植50亩茶园,年收入达6万元。
目前,该县已实施生态移民1万多人,有效缓解了迁出地的生态压力,也带动了移民开发区的生态建设。到今年初,该县已累计实施退耕还林面积27.3万亩,新建林特产业基地3万亩,森林覆盖率提高了12.8%。生态环境改善推动了该县生态水电大县建设进程,全县水电总装机达10万千瓦,仅柳林乡境内20多条河流已开发大小水电站18座,年售电收入3000多万元,昔日的“穷山恶水”变成了“金山银水”。在北部楼台和西部宝丰、溢水等乡镇移民安置点,多数移民户用上了沼气、太阳能等新型能源,建成沼气生态农业庭院,依靠发展冬枣、茶叶、蔬菜等绿色产业走上了致富路。

四年级英语手抄报内容
英语的寓言啊:The Ant and the Dove
An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning.
A Dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her.
The Ant climbed onto it and floated in safety to the bank. Shortly afterwards a bird catcher came and stood under the tree, and laid his lime-twigs for the Dove, which sat in the branches. The Ant, perceiving his design, stung him in the foot. In pain the bird catcher threw down the twigs, and the noise made the Dove take wing.

英语小故事: The one-eyed doe
A doe had lost one of her eyes, and could not see anyone approaching her from one side.
In order to avoid any danger, she always ate on a high cliff near the sea, and looked at the land with her good eye when she was eating.
By this means she could see whenever the hunters approached her on land.
But one hunter found out that she was blind in one eye. He rowed a boat under the cliff, and shot her from the sea.
译文: 一只眼睛的母鹿
有头瞎了一只眼睛的母鹿,没有办法看到从瞎了的那只眼的方向靠近她的东西。
为了躲避危险,她总是在海边的一处高崖上吃草。在她吃东西的时候,她用那只好的眼睛注视着陆地。
用这种方法,她防备来自陆地上的猎人的袭击。
但是一个猎人发现她的一只眼睛是瞎的,就划着船从海上将她射杀了。
英语作文: A Trip
I went hiking to a mountain with my friends last summer. It was a good trip at the beginning but something unexpected happened on the half way. One of my friends suddenly felt a terrible pain in his stomach and he couldn't move any further. Nobody knew what to do. One girl tried to call her mum with her mobile phone but there was no signal in the mountain area. Luckily we brought a tent with us. We put it up and let him rest in it. He took some medicine. Then he drank some water, and ate some food. After a while, he felt much better and we walked on. We all enjoyed ourselves on the top of the mountain.
