Describe an important invention that you think has positively influenced the human race.
You should say:
What the invention is
Who invented it
What changes it brought
and explain how it has positively influenced the human race.
It is really tough to pick one particular scientific invention that had positively influenced human race as there are possibly hundreds and thousands of such inventions. I would like to pick the ‘Light Bulb’ as one such invention that has very positively influenced the human race.
很难选出一项对人类有积极影响的科学发明，因为这样的发明可能有成百上千种。我想选择“灯泡”作为一个这样的发明已经非常积极地影响了人类。
This single invention of science has uplifted the human race towards prosperity and the modern world. Think about the world without any lights in the dark and we would have been no different than living in a cave. The great scientist Thomas Edison is credited to invent the light bulb and till then many improvements have been done to it.
The bulb is the main source of illumination and light at night time when the Sun is hiding at the opposite side of the world. We are so habituated with the electricity and light bulbs that we might wonder if it is a life-changing invention or not.
科学的这一单一发明促进了人类走向繁荣和现代世界。想想在黑暗中没有灯光的世界，我们和生活在洞穴里没什么区别。伟大的科学家托马斯·爱迪生发明了电灯泡，在此之前，人们对它做了许多改进。
But think about living your life for few days without the bulbs and then you would realize the true importance of this single invention. Some may argue that fuel powered lighting system could have been alternative to it, but the reality is that that would have been too expensive and could not have been an easy source for lighting the houses,Think about the other living beings other than human; they mostly get back to their living place in the evening and except some nocturnal animals and birds, most of them stay at their living place till the morning.
但是如果你想过几天没有灯泡的生活，你就会意识到这一发明的真正重要性。有些人可能会说，燃料照明系统可以替代它，但现实是，那太贵了，不可能成为照明房屋的简单来源，想想人类以外的其他生物;它们大多在晚上回到它们的栖息地，除了一些夜行性的动物和鸟类，它们大多数呆在它们的栖息地直到早上。
They rarely do anything at night and that’s because they are afraid of the dark and have no vision to see at night. As the human, we could have some lighting system if we did not know how to illuminate the light bulb but that would not have been so widespread without the invention of the light bulb. Scientific inventions are interrelated and one invention or theory inspired and accelerates the invention of other important inventions.
他们很少在晚上做任何事情，那是因为他们害怕黑暗，在晚上看不到东西。作为人类，如果我们不知道如何点亮灯泡，我们可能会有一些照明系统，但如果没有灯泡的发明，那就不会如此普遍。科学发明是相互关联的，一项发明或理论激发并加速了其他重要发明的发明。
The Light bulb is one such invention that has inspired the invention and research of other inventions. This is the single invention that has made us free from being active only at day time when the sun is there.
灯泡就是这样一种发明，它启发了其他发明的发明和研究。这是唯一的一项发明，它使我们在只有太阳存在的白天不活动。
