Task： Motorized flight is the greatest invention in the history. No other inventions exerts greater impact. do you agree or disagree.

　　New scientific inventions have dramatically changed the way people live. Motorized flight is one of the key inventions in the history of technology. However， as far as I am concerned， the impact of motorized flight can be not considered the greatest among all inventions.

　　Apart from the motorized flight， other inventions have contributed enormously to our everyday life as well. Especially since the “industrial revolution” took place， our lives have been made much more convenient by inventions such as trains ， computers and internet. Each invention has its different functions and works in different fields. As a result， it is hard to compare that which one exerts greater impact. Even a pair of chopsticks has impacted for almost 5000 years on the habit how people eat in China.

　　In addition， we should not only focus on the motorized flight itself to announce that it is the most important invention. Admittedly， it made the dream of human being become true， which people had been dreaming for so long to fly in the sky. From thunder and lightning to the electrical light， from the invention of the wheel to the car，and of course， without the invention of the screw； nail； hammer and motor， there will be no airplane.

　　In conclusion， the steps of inventing new products will never stop in our fast-developing society. Without suggesting all the inventions are equally good， I think we should not ignore other small inventions as well， because every invention can be our friends and support our way of life.
