138"Only through mistakes can there be discovery or progress."

是寂寞UID: 2680526

这段我的论点是：Discovery and progress are always born in mistakes，想让大家帮我评改下这段。 写完这段之后自己先改了下，但是总觉得很怪~用词、语法啊就感觉不自然；还有论证展开自己觉得太长了，这段本来想用两个例子一个是诺贝尔，另外一个是永动机，但一个例子就用了100多词，不知道怎么样写能既精简又显得每个例子都充分展开了。

Discovery and progress are always born in mistakes. When it comes to the advancement of science, this saying is used to witness the rough road that leads to scientists’ hard-won success. For instance, Alfred Nobel, an outstanding chemist and the establisher of Nobel Prize, had experienced dramatic numbers of failure before his epochal invention came up. Once when he conducted an experiment on the characteristic of nitroglycerin, an unexpected explosive happened which killed his younger brother and four other partners. Nevertheless, Nobel was not frustrated with the deadly mistake and went on his research. Several years later, Nobel finally achieved his goal and invented what he called dynamite which to a great extent changed the history of human beings. Without so many fiascos, shall we say, Nobel could not make such significant progress in the process of his invention. Therefore, it is obvious that mistakes give rise to the discovery and progress.
