作文一
I think the greatest invention of the last century was the airplane. The invention of the airplane has brought the distance around the world closer. As long as you get on the plane, you can travel around the world, even tens of thousands of kilometers away, and you can reach it in a few hours. On December 7, 1903, the plane invented by the Wright brothers rushed into the sky. The Wright brothers invented the world's first airplane, the Flying One. During the Wright brothers' test flight, the pilot one successfully flew four times, with a flight duration of 97 seconds and a flight distance of 441 meters. Although this number is not worth mentioning now, it is an epoch-making flight, which represents the arrival of the era of human flight.Since then, aircraft technology has made rapid progress, bringing the dream of flying to heaven since ancient times. The airplane has also become an indispensable tool for modern civilization. It has profoundly changed and affected people's lives and opened the history of people's conquest of the blue sky.
Apirin, I think it is the greatest invention of the 20th century. Aspirin is just a small pill, but it is a good medicine for relieving heat and pain. Since its invention, it has appeared all over the world. This pill means that the pain that has plagued mankind for many centuries has found a way to relieve it. For example, headache and toothache can be well treated, so that patients do not have to worry about being too painful to rest well after illness.
So far, aspirin has been used for hundreds of years, and has become one of the three classic drugs in the history of medicine. Up to now, it is still the most widely used antipyretic, analgesic and antiinflammatory drug in the world, and also the standard preparation for comparing and evaluating other drugs. It has antithrombotic effect in vivo. It can inhibit the release of platelets and inhibit platelet aggregation, which is related to the reduction of TXA2 production. It is clinically used to prevent the attack of cardiovascular and cerebrovascular diseases.
I think the greatest invention of the last century was penicillin, the killer of infectious diseases. Its appearance saved the lives of tens of millions of people. Since ancient times, infectious diseases have been one of people's "natural enemies". In ancient times, when science and technology were not developed, once infectious diseases were encountered, it meant death. Several generations of medical experts have made unremitting efforts for the prevention and treatment of infectious diseases. Later, some studies showed that bacteria were the culprits leading to the large-scale spread of infectious diseases, so people tried every possible way to find ways to eliminate infectious disease bacteria until penicillin was discovered, ending an era when infectious diseases were almost untreatable.Penicillin is a major invention, from an accidental discovery to a wide range of applications that can benefit mankind. The discovery and mass production of penicillin saved the lives of millions of patients with pneumonia, meningitis, abscesses and sepsis, and saved many patients in time. The emergence of penicillin made a sensation in the world at that time. In recognition of this contribution to the benefit of mankind, Fleming, Chane and Flory jointly won the Nobel Prize in Medicine and Physiology in 1945.
