科学技术作文篇1
the development of science and technology makes our life more comfortable and convenient.however,scientists have created many problems,which are not easy to be resolved,such as air pollution,the deterioration of environment and the scarcity of natural resources,to which we must some solutions.
modern science and technology render people many advantages.modern telecommunication shortens the distance between people and makes communication much easier.internet is widely used now not only for collection of abundant information but also for correspondence.email,the most effective communication device now,is becoming very popular.besides,telephone and mobile phone make contact more convenient than before.
modern transportation,such as airplanes and high-speed trains make our journey smooth and fast.with the help of modern transportation,people can go everywhere they prefer to.the journey to outer space and other planets is not a dream any more.rockets and space shuttles can help us realize the dream of space travel.
modern medicine prolongs peoples life and relieves patients of sufferings from many diseases.cancer and aids are fatal to peoples health.thanks to the endeavors scientists have made,these diseases become treatable.
however,the process of scientific development also arouses many sever problems to our human beings.internet,though widely used in modern communication,is easy to be destroyed by computer virus.outer space exploration has produced much waste in the space.a tiny metal,a screw,for example can destroy a flying man-made satellite.industrialization is making natural resources become scarce.
confronted with these problems,scientists are seeking prompt and feasible solutions.the development of science and technology bring about both positive and negative effects to us.we must eliminate the positive effects to the least extent.

all kinds of inventions made possible by technology are designed to be the slaves of human beings, if human beings are not to be slaved by machines. once upon a time, we were plain people, but that was before we began having relationships with technological systems.
by getting involved with computerized machines, we could not help changing the way we live and the way we work, for better or for worse it can be realized that life is more complex because much of modern technology is not born to meet primary human needs, and many "unnecessary" inventions are producing negative effects on a living style that used to be relatively simple. thus, there is an overwhelming feeling of complexity in the sense that machines act like humans and humans act like machines.
now that "intelligent" machines such as robots are widely applied to take the place of human beings because they are capable of doing many useful jobs, although making many people jobless. those who cannot work with computers are disadvantaged and therefore helpless while the traditional skills and simple ways of life are fading away, never to return again.
科学技术作文篇3
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.
科学技术作文篇4
今天上午，我和妈妈一起去了中国科技馆，我和妈妈先买了去科技乐园的门票，本来还想买主展厅的门票，可是售票员说:“科技乐园一天可能参观不完。”所以我们没有买主展厅的门票。
我们进了科技乐园后，首先看到了一朵大浪花形的柱子，上面有三个字是“戏水湾”，浪花上面还有一些海洋生物，如：小鱼、海星、海马、小虾......我看见一座好大的房子，上面写着“科技城堡”，我对妈妈说：“我想去科技城堡玩。”妈妈说：“可以，我在下边等你。”于是我去了科技城堡。它的第一层也没什么东西，于是我就上了第二层，第二层有个“深井”，我把眼睛对准深井的小洞，我看见了一个立体的井，里面没有水，还有一个投球的游戏，就是让你把小球投进洞里，球就会从下面出来。在第三层的台阶上，我看到了好多的'自己，因为有两面的镜子，分别在台阶的两侧，它们互相照，就形成了这个样子。第三层有个天文望远镜，我看了看，还真看见了星星，我从三楼一个螺旋滑梯滑了下一楼，吓得我脸都白了，还被电了好几下。我又跑到三楼问了一个叔叔，“叔叔，为什么滑梯也会有静电呢？”叔叔说：“因为这是塑料的，所以会有静电。”我又滑了一次，这一次我把手放在膝盖上，这次没被电着。
我又玩了一个叫“小拖拉机手”的游戏，前面有个屏幕，后面有一个机器，像一个拖拉机一样，它的下面有两个铁片，一个油门一个刹车。这个游戏让我明白了种地有四步：翻地、播种、插秧、收割，还明白了农民伯伯种地有多么地辛苦。
还玩了很多游戏，如：寻找动物、谁是害虫......我们一天才参观完，参观完科技馆后我们高兴的回家了。
科学技术作文篇5
现在是公元2026年，我住在一个科技住宅里。
先看看我家的防盗门吧，它不用钥匙开，只要前来的人敲一下门，它就能自动分辨出那个人是好意还是恶意，然后再决定是否开门。
再看看我的家吧，电视可好看了，它不仅不会损害眼睛，还能防治近视;电视上有一个小小的灯，它不用电，仅仅依靠平日里收集的太阳能就可以维持工作;电视前边是沙发，十分柔软，躺下去就像躺在棉花上一样，而且，它还能自动按摩，解决你一天工作的疲劳;客厅里的灯是仿花做的，共有七个花瓣，这七个花瓣，外形颜色分别是红橙黄绿青蓝紫，射出的光像是光彩夺目的彩虹，但不刺眼。
如果再仔细看看客厅，就会发现客厅一角还有一个怪模怪样的小箱子，这可是我的最新发明，你可以把你的书都放在这个箱子里，看到这里，你一定好奇吧:如果书都放在这箱子里，箱子应该很大，可为什么这么小呢?告诉你吧，这箱子能把装进的书都缩成小方块，书越多，就缩得越小，等到用的时候再恢复到原来的大小。当然，这还不是这个箱子的最大作用，它的最大作用是你一有什么问题，只要按一下箱子上面的按钮，它就知道你想知道什么，然后很快就在屏幕上出现内容，并有一个动人的声音在给你讲述。走进我的卧室，映入眼帘的'是一张床，这个床从外形上看和平常的床差不多，但它的作用却大着呢!床面温度能根据季节的温度变化自动调节，夏天，床面会非常舒爽清凉，冬天，床面会变得十分暖和，不用盖很厚的被子，更不用穿很多的衣服，而且，你躺下后它能自动给你按摩让你很快入睡。它还能自动叫你起床，当你睡觉时想到明天需要什么时间起床，它就会按时提醒你……这就是我20年后的家，一个高科技的现代家居环境。

today, my mother and i visited shanghai science and technology museum. looking from afar, the science and technology museum is like a big ball. only when approaching can we find that the science and technology museum has four floors and a mascot of the world expo, haibao, stands at the gate.
first, we went to the aliens hall on the first floor underground. all the things displayed in the hall are related to aliens. there is an alien lying in the cabinet of a room. there are six fingers, six toes and a big stomach. it seems that there is a child in it. the alien has a big head and a bloody scar on his leg.
then we went to the birds and animals museum on the second floor. we went into a bat cave. there were a group of bats hanging upside down in the cave. as soon as people went in, they made squeaking noises. mother was shaking and screaming with fear. i'm not afraid at all. i told my mother that it was made by imitating real animals.
then, we went to the animal world again. the staff said that these were all specimens. look, that leopard is biting a fawn, running, making it lifelike. it's so lifelike!
finally we went to the robot hall, where there are all kinds of robots. the most interested robot will sit in front of the piano and pretend to play. it will play whatever song you sing. i really admire it!
this visit opened my eyes. i must study hard and strive to be a scientist when i grow up.
科学技术作文篇7
经过我几十年的研究，我发明了一种神奇的回收桶，以前的回收桶只是一个摆设，扔垃圾的人依然我行我素，照扔不误。
我发明的回收桶有许多神奇的功能，不信？听我慢慢说。
这个回收桶非常拟人化，脸方方的，眼睛、鼻子、耳朵一个不少，还有一张张得很大的嘴，怪吓人的，这是给不讲公德的人看的。放心它不会伤害你的。它的身体是圆柱体的，屁股上有一个洞。它的双手和双腿有细有长，走起来非常灵活。
白天，它在没事的时候用手指的缝吸收空气中有毒的气体，在体内过滤，生成新鲜的氧气排放出来。汽车发出烦人的噪音，回收桶会用鼻子吸收噪音，放出优美的音乐，这优美的音乐可以使人神清气爽。一位病人走来了，在纸上写下自己得了什么病，把纸放进回收桶里，“叮咚”，一盒药从回收桶的`屁股了“拉”了出来。什么药都有，所以什么病都能治好。病人拿着药高高兴兴的走了。看，来了一个小孩儿，回收桶的嘴很高，就算小孩跳起来也扔不进去，怎么办呢？只听“吱”的一声，回收桶降低了高度，这个小朋友把垃圾扔了进去，蹦蹦跳跳地走了。
这种回收桶还会在大街上巡视，看见有谁乱扔垃圾，第一次会严厉的制止，并把那个人记在本子上。一年后如果没有被回收桶发现乱扔垃圾所有的记录就会取消；如果一年内又被发现了乱扔垃圾，回收桶会把那个人带到警察局接受处罚。
回收桶不光白天很忙，晚上也很忙，如果它发现前边又能一堆垃圾，就会用吸尘器把垃圾吸到一个大盒子了然后送到垃圾回收站，如果前面有一片污水，它会用鼻子把水吸到体内过滤一下然后再把清水倒进河里。‘
我发明的神奇回收桶不错吧？我一定把它大量投入生产，让人类的环境变得更美丽！
科学技术作文篇8
我们身边有许多科学现象，平时只要留心观察，就一定能发现它们。一天，我在厨房帮阿姨做饭时，突然一个空盒子从架子上滚落下来，正好掉在一半凸面向上的蛋壳上。我想蛋壳肯定碎了，不料它却完好无损。我非常疑惑，蛋壳不是很脆弱的吗？怎么这次连一条裂纹也没有呢？我决定要自己弄清楚。
我做了个实验：把蛋壳凸面向上放在桌上，让铅笔对准蛋壳，在离蛋壳5至10厘米的空中自然落下，蛋壳完好无损；再把蛋壳反过来，凹面向上，下面垫个小杯子后重复原来的过程，蛋壳就被轻而易举地戳破了。
这是怎么一回事呢？我在图书馆查找资料，终于找到了答案：凸曲面能把外来的力沿着曲面均匀地分散开，使它能受得住较大的压力。蛋壳之所以坚固，完全是因为它的`形状是凸出的。各种穹顶和拱门之所以很坚固，也是由于同样的道理。电灯泡看起来好像很脆弱，实际上却极坚固。这同蛋壳的道理一样。直径10厘米的灯泡所受的压力，在75千克以上，相当于一个成年人的体重。
而在一个夏天的中午，我热得口干舌燥，心想：“要是有杯冰水喝就好了，厨房里应该有水。”走进厨房，果然不出我所料，桌子上放着满满一壶水。我高兴极了，马上把水倒进杯子。一股热气冒出杯口，原来，这是壶开水！
怎样才能让开水迅速凉下来呢？无知的我把水放进冰箱，心想：“待会儿就能喝到冰水了。”
过了几秒钟，只听“砰”地一声，水沿着冰箱缝徐徐流出。我被吓了一大跳，迅速打开冰箱门，冰箱里的水泼洒下来，杯子碎片劈哩啪啦落了一地。我顿时愣住了，好好的杯子怎么会爆呢？通过查阅资料，我知道了杯子爆炸的原因，是热胀冷缩的原理：因为杯子里装的开水使杯子内部受热膨胀，冰箱里的温度又使杯子外部受冷收缩，就这样，杯子内部不断膨胀，外部还是凉的，迟迟不膨胀，杯子就爆了。
我们身边还有更多能够扩展知识面的科学现象，你们发现了几个？
