名师解析
感觉这个话题还是有很多可说的，但是有个一个问题是，如果不记得发明人怎么办呢?其实，这个时候，就应该把视线前移，想想那些根本没人知道发明人的发明，比如人工取火，车轮等等，是不是问题反而好说了一点呢?
高分范文
I would like to pick the “Light Bulb” as one such invention that has very positively influenced the human race. This single invention of science has uplifted the human race towards prosperity and the modern world. Just to think of a world without any lights in the dark! 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.
Light bulb is a marvelous invention. People of all ages have benefited from it greatly. However, nowadays we are so habituated with the electricity and light bulbs that we might have ignored that it is a life-changing invention. But think about living your life for a few days without the bulbs and then you would realise the true importance of this single invention. Besides, 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.

某网评定的几个改变世界的发明
plow(犁)：入选理由
No one knows who invented the plow, or exactly when it came to be. It probably developed independently in a number of regions, and there is evidence of its use in prehistoric eras. Prior to the plow, humans were subsistence farmers or hunter/gatherers. Their lives were devoted solely to finding enough food to survive from one season to the next. Growing food added some stability to life, but doing it by hand was labor intensive and took a long time. The plow changed all that.
wheel(轮子)：入选理由
The wheel made the transportation of goods much faster and more efficient, especially when affixed to horse-drawn chariots and carts. However, if it had been used only for transportation, the wheel wouldn't have been as much of a world-changer as it was. In fact, a lack of quality roads limited its usefulness in this regard for thousands of years.
A wheel can be used for a lot of things other than sticking them on a cart to carry grain, though. Tens of thousands of other inventions require wheels to function, from water wheels that power mills to gears and cogs that allowed even ancient cultures to create complex machines. Cranks and pulleys need wheels to work. A huge amount of modern technology still depends on the wheel, like centrifuges used in chemistry and medical research, electric motors and combustion engines, jet engines, power plants and countless others.
printing press(印刷术)：入选理由
The printing press allowed enormous quantities of information to be recorded and spread throughout the world. Books had previously been items only the extremely rich could afford, but mass production brought the price down tremendously. The printing press is probably responsible for many other inventions, but in a more subtle way than the wheel. The diffusion of knowledge it created gave billions of humans the education they needed to create their own inventions in the centuries since.
