When Bill Gates made his decision to drop out from Harvard, he did not care too much about the result. Gates entered Harvard in 1973, and dropped out two years later when he and Allen started the engine of Microsoft. Many people did not understand why Gates gave up such a good opportunity to study in the worlds’ No.1 university. Now, Microsoft has become the biggest software company in the world and Bill Gates has become one of the richest men in the world.
政治：
Martin Luther King Roosevelt’s New Deal Policy during the Great Depression, among various examples, greatly supports my argument. While Roosevelt had a thorough and long-term understanding of the detrimental effect, which derives from the new regulation and acts on capitalists and the overall market, he hewed to this policy, with great determination, which later brought the revival of American economy. The reason why he was so unswerving is that he was aware that the desirable consequences of this policy would ultimately outstrip the undesirable ones.
If Roosevelt had not subordinated the interest of traditional capitalist and built a contact between the free market economy and the regulation from the government, Americans might still suffer from the terrible effects from the Great Depression in the current day. Granted that Roosevelt implemented many policies under the opposition from the business, we do not dismiss him as acting irresponsibly. On the opposite, we have to celebrate these policies because they finally benefit the country overall as a comprehensive and far-reaching regard. In this way, Roosevelt embodies what an insightful leader may be who achieve a balance between public wish and personal decision.
Although Lincoln has perished in history long ago, we still could see every generation of government official abeting themselves with Lincoln’s prestigious motto“of the people, by the people and for the people.”
文学：
In “Anna Karenina”, Leo Tolstoy successfully created a classical character Anna, whose legendary life is replete with reflections of the nineteenth century of Russia, which based on the author’s authentic and vast knowledge of that period of time. Thus these reflections are reasonable. In addition, what renders this character so distinguishable from others is the unrestrained imagination and enthusiasm. It is not difficult to imagine how less sparkling this work would be if the writer had been less knowledgeable and had poorer imagination.
艺术：
From the prestigious work Last Supper by Da Vinci, one of the greatest painters in the Renaissance period, we can observe the painter’s insightful understanding and professional knowledge of the mid-century European religious. However, it was not until the birth of one of his another work Mona Lisa, which is not only a great reflection of the artist’s imagination, but also stirs the viewer’s illusions, did he reach his peak in the field of art.
