The speaker points out that the discovery or progress, in other words, can be gained only through mistakes. I fundamentally agree with this assertion, primarily because it accords with common sense and our personal day experience. The speaker fairly summarize the  relevant relationship between the mistakes and discovery simply saying, no mistakes no dicovery or progress, which has been widely accepted in the field of scientific research and even reinforced.

  Generally no one can escape from making mistakes. Mistakes accompany us through all our lives because there is nobody born with prophet’s gift that could enable us to avoid making mistakes. Taking a close observation through (the) history, even the most successful and bright people, who may more smart than you and me, also make innumerable mistakes before they success. However, they are not afriad of making mistakes and become better learners in face of them. As we all known, Faraday, the father of electromagnetism, had had hundreds of thousands times of failures before finally success in producting the first generator. His successful examples indicates enfronting the mistakes bring about progress and discovery. However, mistakes are not always bring the discovery and progress to the end, sometimes failure would be come into our life. Namely if one person cannot summarize the lapsus from the failture or errors, he or she could not be successful in the following process.

 People can learn a great deal from their own mistakes because of the simple reason that after experiencing a big frustration, the bitter memory will be craved in one’s mind and remind him or her of never repeating the same mistake again.

The Second world War is a tremendous mistake that happened in human history. The Jews were crudely killed by the NAZi, Japan killes(killed) almost 300,000 Chinese people in Nanjing,1937. How can we account the inhumanities during the War that lasting almost 8 years? However, it is lucky to see, after the War, the globle maintain the peace for 60 years, as the huaman realized the peaceful circumstance is essential  for ecnomic and culture development.

Another benefit we get from our mistakes is that we discover the limit of currrent method of dealing with problems and probe into a new alternative one. In this way, through mistakes we can approuch/approach  the right solution of them, in other words, the previous errors adjust the direction to where would be going to and success in the breeding of great success. Many scientists begin a study by finding out what others have made on a particular problem. The greatest inventor Thomas Edision finally success in finding the fit material of light bulb is a provable evidence. He found out what mistakes have been appeared, thereby avoiding unnecessary repeates. After 1000 times the bulb was burn. Moreover, 6000 times of failing shootings work out our famous football player, Beckham.

We make significant discovery and progress not only through mistakes made by ourselves but also through analyzing the mistakes in other people lives and avoid the same ones. Thus, the most important is we should learn the attitude towards the mistakes from the famous and successful people, which will encourage us to probe in ourselves.

  In sum, the speaker asserts that it is through mistakes that discovery or progress are made. In fact, our personal growth as individuals, as well as progress in science and other areas, are based on so called mistakes.
