鼓励青年去学习科学的英语作文
Science change life
Science always develops with human progress, and human life also changes with the progress of science. Forty years ago, my parents watched black and white TV, water to a far away to pick, cooking to rise on the stove, travel to go a long way. Now, we watch the LCD TV, to use water, just twist the tap gently, just press the button when cooking, travel when you just wave, you can step on a taxi, to where you want to go.
Before, night lighting is a troublesome thing, later, Edison invented the electric light, solved this problem, from then on, people can live at night like the day; before, with foreign friends communication, is almost impossible thing, since the Internet, let also become a reality. It can be said that the progress in science has changed human life.
The previous light gun used light-emitting diodes, not only cost electricity, but also short service life and low brightness; and the current energy-saving lamps, with the same light energy output of ordinary light bulbs, can save a lot of lighting energy and cost. Previously, power generation required a lot of coal, which would not only waste resources, but also pollute the environment; but now, using light energy,
wind energy and water power generation not only solves the waste of resources but also protects the environment. In the past, we needed a lot of procedures, but now the modern production mode not only shortens the production time, but also reduces the waste of manpower, and the production of clothing is more beautiful and generous. In the past of TV, the video tube is not only power consumption, large volume and definition is not high, and now the LCD TV not only thin body, environmental protection and energy saving but also high image definition.
It used to take about three months to walk from Kunming to Beijing, but now it only takes three hours to get there by plane. Tuberculosis was once an incurable disease, but now it has become a common infectious disease as medical technology advances.
It can be seen that the progress of science is inseparable from the development of human beings, and science makes human life more convenient. Now people's life has been inseparable from science, so we should make reasonable use of science and develop science to make the world a better place. Therefore, science changes life, and life promotes scientific development. In order to make our life more beautiful, please all of you
present here together with me, from today on, to strive for the progress of mankind!
科学改变生活
科学总是随着人类进步而发展,而人类的生活也随着科学进步而改变。
四十年前,我的父母看的是黑白电视,用水要到很远的地方去挑,煮饭要在灶台上升火,出游要走很远的路。
现在,我们看的是液晶电视,要用水时,只需轻轻扭开水龙头;做饭时只要轻按电钮即可,出游时你只需招手,便可踏上出租车,去到想去的地方。
以前,晚上照明是件麻烦的事,后来,爱迪生发明了电灯,解决了这个问题,从此,人们晚上也可以像白天一样生活;以前,与国外的朋友交流,几乎是件不可能做到的事情,自从有了互联网,让也成为了现实。
可以说,科学的进步改变了人类的生活。
以前的灯炮用的是发光二极管,不但费电,而且使用寿命短,亮度低;而现在的节能灯,在达到同样光能输出的前提下,只需耗费普通灯泡用电量的1/5至1/4,就可以节约大量的照明电能和费用。
以前发电需要大量的煤炭,不仅浪费资源,而且污染环境;而现在采用光能、风能、水利发电,不仅解决了资源浪费而且还保护环境。
以前我们做一件衣服,需要很多的工序,而现在采用现代化的生产方式,不仅缩短了生产时间,而且减少了人力的浪费,并且生产出来的服装更加美观大方。
以前的电视用的是显像管不仅耗电、体积大而且清晰度也不高,而现在的液晶电视不仅机身轻薄、环保节能还图像清晰度高。
以前,从昆明去北京,走路大约需要三个月,而现在乘坐飞机,只需要三个小时就可以到了。
以前,肺结核是不治之症,而现在随着医疗技术的进步,它已经成为了一种普通传染病。
可见科学的进步与人类的发展密不可分,科学使人类的生活更加便捷。
现在人们的生活已经离不开科学,所以我们要合理的利用科学、发展科学,使世界变得更加美好。
所以说,科学改变生活,生活又推动科学发展。
为了使我们的生活更加美好,请在座的各位与我一起,从今天开始,为人类的进步努力奋斗吧!。
