Science helped mankind in innumerable ways. The scientific inventions have brought about many changes in our lives. The civilizations of the world have progressed by leap and bounds.

    It has helped us in countless ways to make our everyday life comfortable. For travelling or transportation we have many types of vehicles.We need not walk on foot or travel by slow moving bullock carts. Today we have scooters , cars , buses , trains , aeroplanes to take from one place to another.

    The invention of electricity has helped us in many ways. Today nights are not dark , winters are not so cold and summers are not so hot. We use bulbs or tube lights to illuminate our house , room heaters to keep us warm and cooler and AC's to drive away heat during summer days. The invention of T.V. sets has helped us in getting news , entertainment , live telecasts of distant events around the world. We need not go out of our houses to witness those events. Means of communication have vastly improved. Today news travels faster than before. There are E-mails , couriers , telephones , telexes which provide us instant messages. A person sitting in India on telephone can talk to his relative sitting in America or any other part of the world.

    Communication satellites moving in their orbits above the earth's atmosphere can forecast weather reports ,cyclones ,tidal changes in the sea etc. much in advance . These forecasts helps us to reduce the disasters likely to take place.

    We have developed instruments to help us in agriculture ,irrigation , generating electricity , building dams , curing many fatal diseases. Man's life span has been increased with the advancement of the medical science.

    Science has helped us in building multi-stored buildings and elevators helps us to reach even the top floors within no time and that to without straining our legs.

    Computers and internet system help mankind in information technology to a great extent.Today life without science is unthinkable.

    To conclude we can say that science is the magical genie of today. It can do wonders for us if it is used carefully.

    科学以无数的方式帮助着人类。科学发明为我们的生活带来了许许多多的改变。世界的文明因科学而产生飞跃式的进步。

    科学让我们生活的方方面面变得更加舒适。我们可以用多种多样的交通工具来完成我们的旅行和运输。

    我们无须徒步或者坐牛车旅行。今天我们可以通过摩托车、小汽车、公交车、火车、飞机来完成从一个地方到另一个地方的旅行。电的发明也在方方面面帮助着我们。

    今天，夜晚不再黑暗无光，冬天不再寒冷，夏天也不再炎热。我们用灯泡或日光灯来照亮房屋，用暖气取温，用制冷机和蓄电池来驱赶夏日的炎热。电视机的发明帮助我们获取发生在世界各地的新闻、娱乐和电视直播，而无须我们走出房子去目击这些事情的发生。

    今天，人们的交流方式有了很大的进步，新闻比以前传播得更快。

    我们可以通过电子邮件、快递、电话以及电报来获取远方的消息。一个在印度的人可以通过电话与远在美国或者世界任何一个角落的亲戚交谈。在大气层上方轨道中运行的通讯卫星可以为我们预报天气、飓风以及海洋中潮水的变化等等。更进一步讲，这些预报可以帮助我们减少即将发生的灾害。

    人们发明了各种工具来帮助我们进行农业耕种、灌溉、发电、建设水坝以及治疗许多致命的疾病。

    人类的寿命由于医学科学的进步而得以延长。科学帮助我们建造多层建筑，而电梯帮助我们在短时间内达到楼顶而无需劳累双脚。

    电脑和互联网系统帮助人类大大延伸了信息技术的范畴。今天的生活如果没有科学将无法想象。

    总之，我们可以说科学是今天的魔法精灵。如果能够认真加以利用，它将为我们创造奇迹。
