我重新修改过了,请再看看,谢谢~~
With the advance of human history the knowledge that human has accumulated keeps growing with an exponential speed. Accordingly, the perspectives we view the world become much clearer than our ancestors. Nobody will still take the idea that the earth is the center of the universal, which, however, was an unshakable conception among ancient people. However, it is true that we become confused by the complexity and mystery of the knowledge we have gained, even though, of course, those knowledge is invaluable treasure for our all human beings.
From my point of view, the more knowledge we gain the further we will think, during which people may be involved in an unknown world. It is very common for anyone to feel intricate or cryptic when engaged in a new area that we know nothing about. In the past when people neither know nothing about petroleum nor realize to utilize it and even did not care its existence. Now, nevertheless, it is much different. Presently our life strongly depends on the by-products of petroleum such as gasoline, kerosene, rubber and so on. Petroleum, as we all know, is limited, we have to search some kind of substitute for petroleum. Therefore, the whole thing becomes more and more complicated. In other words, people did not have such problem before we made use of petroleum, which makes us feel things become more involutes instead of being accessible with more knowledge. Similar things take place in other realms as well.
In the realm of astronomy, human have made every effort to explore the cosmos long long ago. Until now we have collected a number of information about the constellation so as to have a general idea of the outer space. Furthermore, the astronomers and scientists have put forward some acceptable assumptions to explain the various phenomena of the universal. Take Stephen Hawking as an example, he believes that universal and time have a beginning in the Big Bang, expatiated in his book A Brief History of Time. His theory results in the debate how to prove that the cosmos is expanding continuously. To collect the evidence and information is such a time-consuming and laborious task that the theory is still a perplexing hypothesis.
In the realm of anatomy, how human brain functions is still a mystery for us. In the past anatomy was illegal, which made it impossible for the scientists and doctors to know the conformation of the human body. But now things have changed. The students in medical colleges have the opportunity to anatomize human body in class. However, it is still unaccessible for us to understand the function of the brain, which is an organ with thousands of nerves. In other words, the brain is too intricate for us to comprehend.
Although more and more knowledge makes things tanglesome and occult, we still can utilize the abundant knowledge to serve us. Attaining a number of knowledge, people may understand more about the unknown world and make great progress in some new field. From this point of view, mankind is always going ahead continuously. With gripping the knowledge of atom, we are in control of the nuclear power that can create a numerous amount of power without any pollution. In addition, people may even master nature, which is unbelievable in the past. For example, in order to alter the arid condition, dry ice spread by plain may cause to rain. In the other hand, knowledge should be applied for the sake of human not destroy us. For instance, the ingenious doctor, in the latest movie Spiderman, narrowly spoils the New York city without proper use of his knowledge. Therefore, knowledge, appropriately utilized, may contribute to serve every aspect of our life.
The history of mankind, in my opinion, is actually a history to explore the unknown. Just as a philosopher said (and I paraphrase):" If we compare the known part of the world as the space within a circle, and the unknown part as the space outside it, the more we acquire, the more the unknown part that we can contact." I believe that what really matters is that how knowledge can benefit human being instead of whether it makes things complex or mysterious.
