一:英文科普短文
The Internet is a giant network of computers located all over the world that communicate with each other. The Internet is an international collection of computer networks` that all understand a standard system of addresses and commands, connected together through backbone systems. It was started in 1969, when the U.S. Department of Defence established a nationwide network to connect a handful of universities and contractors. The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disaster by providing multiple path between users. People on the ARPNET (as this nationwide network was originally called) quickly discovered that they could exchange messages and conduct electronic "conferences" with distant colleagues for purposes that had nothing to do with the military industrial complex. If somebody else had something interesting stored on their computer, it was a simple matter to obtain a copy (assuming the owner did not protect it). Over the years, additional networks joined which added access to more and more computers. The first international connections, to Norway and England, were added in 1973. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say exactly how many users "On the Net". The Internet is the largest repository of infor......余下全文>>
二:科普小短文里面的举例子的句
楼主你好
以下都是科学小品中的举例子
1、科学家提出许多设想,例如,在火星或者月球上建造移民基地。
2、苏州园林在每一个角落都注意图画美,比如在阶砌旁栽几丛书带草。
3、例如菊花,萎谢之前微呈红色,表示它这时也含有少量的花青素了。
4、电脑的确可以节约时间提高工效,比如说,玩翻纸牌游戏的时候你根本就用不着洗牌。

6、我国曾经发现过一头近四万公斤重的鲸,约十七米长,一条舌头就有十几头大肥猪那么重。
7、水面假如成河道模样,往往安排桥梁。假如安排两座以上的桥梁,那就一座一个样,决不雷同。
8、很多物质的颜色取决于它自身的成分,就拿长江来说吧,它的水中含大量泥沙,所以是黄色的。
9、中国的茶叶的种类有很多,比如绿茶、红茶、青茶(乌龙茶)、白茶、黄茶、黑茶、药茶、花茶等。
10、如大丽花,原产墨西哥,只有八个红色花瓣。人工栽培的历史仅二三百年,却已有上千种形状,颜色不同的品种。
11、有一种号称“海中之虎”的虎鲸,常常好几十头结成一群,围住一头三十多吨重的长须鲸,几个小时就能把它吃光。
12、鲸要是张开嘴,人站在它的嘴里,举起手来还摸不到它的上腭;四个人围着桌子坐在它的嘴里看书,还显得很宽敞。
13、20世纪,电视、程控电话、因特网以及民航飞机、高速火车、远洋船舶等,日益把人类居住的星球变成联系紧密的“地球村”。
14、感恩节,感恩常在,选一份真诚的礼物,熟悉的人,可以根据各自的爱好,比如一本书,一张CD,不熟悉的人,可以送上一束鲜花。
15、在困难面前,我们不能退缩,只能挺身而进,执着努力。像李时珍和霍金一样,只有经历风雨,才能看见彩虹,才有可能看到黎明前的曙光。
16、为了给混噩的世人敲响警钟,联合国在大力推行全球生物多样性保护行动的同时,特地将年“六五”世界环境日的主题定为“为了地球的生命”。
17、我国的石拱桥几乎到处都有。这些桥大小不一,形式多样,有许多是惊人的杰作。其中最着名的当推河北省赵县的赵州桥,还有北京丰台区的卢沟桥。
18、正如张丽君说过:“畏惧才是真正的怜惜与恭敬。”一个理智的人,过分大胆无畏,有时只是暴虎冯河,我们应当明白:有所畏惧,收获的将会是柳暗花明的结果。

21、身体是实践的施行者,灵魂是思考的场所。身体与灵魂是人类生存所不可或缺的一部分。实践与思考同样是相互作用,相互促进,他们就如那撑起人字的一撇一捺,一个也不能少。
22、世上有很多东西是可以挽回的,比如良知,比如体重。但不可挽回的东西更多,譬如旧梦,譬如岁月,譬如对一个人的感觉。放弃一个很爱你的人并不痛苦,放弃一个你很爱的人才是痛苦。
23、万千事物无一具有两面性。正所谓水能载舟,亦能覆舟。这正如人生之路上的绊脚石一样,总是阻挡着你的去路。然而,众多的“绊脚石”聚在一起时,便成了人生路上的铺路石了,奠定走向未来的道路。
24、陶渊明的一生选择的是站立。虽然自己的生活穷困潦倒,但为了避开官场的污浊,他不为五斗米折腰,选择了归隐田园。于是,便有了“采菊东篱下,悠然见南山”的自由和“晨兴理荒废,带月荷锄归”的闲适。

Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old.
不久之前,许多人认为婴儿的基本需求是食物和保持温暖干燥.人们以为婴儿只有到了五六个月大的时候才会开始学东西.
Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to identify which experiences can influence healthy development in human beings.
然鼎,美国的医生声称婴儿在他们出生的头几天便开始学习.肯尼迪施莱佛国立儿童健康和人类发展机构是联邦政府代理机构,他的目标是鉴别那些能影响人类健康发展的经验.
Research scientists at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings

我们的水球
有人说,我们的地球应当叫水球。这是有一定道理的,因为我们生活的这个星球有水,而且71%的表面积被水占着。在宇航员看来,地球是一个蓝色的球,十分璀灿,太阳系家庭中独一无二。地球拥有的水量非常巨大,总量为13.86亿立方千米。其中,96.5%在海洋里;1.76%在冰川、冻土、雪盖中,是固体状态;1.7%在地下;余下的,分散在湖泊、江河、大气和生物体中。因此可以说,从天空到地下,从陆地到海洋,到处都是水的世界。
惊天动地的水循环 ,全世界的水是一个有联系的整体。海水在阳光的照射下,不断蒸发,水汽弥漫在海洋上空;一部分水汽被气流带到陆地上空,遇冷就凝结成细小的水滴,变成云,降落到地面就是雨或雪;雨雪水落地后,有的流到洼坑里,有的渗入地下,有的流入小沟,汇进江河,奔向海洋。无数小水滴就是这样一刻不停地在世界上旅游。水循环保证了人类淡水的供应。知道水的循环以后,你就能解释:云的故乡在哪里?为什么江河里日日夜夜总是川流不息?为什么千万年来那么多江河水流进海洋,而海洋不见满溢出来?
淡水在哪能里 地球上的水,尽管数量巨大,而能直接被储们生产和生活利用的,却少得可怜。首先,海水又咸又苦,不能饮用,不能浇地,也难以用于工业。其次,淡水只占总水量的2.6%左右,其中的绝大部分(占99%),被冻结在远离人类的南北两级和冻土中,无法利用,只有不到1%的淡水,它们散布在湖泊里、江河中和地底下。与全世界总水体比较起来,淡水量真如九牛一毛。
Our water polo
Someone said, our earth should call water polo. This is a reason, because of our lives, and our planet is water surface area by water 71% takes. The astronauts opinion, the earth is a blue ball, very resplendent in the family, the solar system is unique. Earth has very great volume of water, total 13.86 billion cubic kilometers. Among them, 96.5% in the sea, The frozen earth, snow in glaciers, cover, is a solid state; 1.7% in underground, The remaining, scattered in the lakes, rivers, atmosphere and organisms. Therefore we can say that from the sky to the ground, from land to sea, the water is all over the world.
Earthshaking, the world's water circulation water is a contact of the whole. Seawater in sunshine, constantly evaporation, steamy over the sea, Part of water vapor was brought to land, air over they get cooler condenses into s......余下全文>>
