参考范文：爱迪生与灯泡

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. 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.

But think about living your life for few days without the bulbs and then you

would realise 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.

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.

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.
