1. Talk about the benefits and costs of pursuing a scientific career. 谈论追求科学事业的好处和代价。 I have ever thought about the reason of a scientist pursuing a scientific career. Is it can bring you great wealth? Maybe not. Science is always a quiet, humble, great undertaking. Science is not a word that can be made clear in two or three sentences. Science is a dream. It can be intoxicating and addictive to uncover its secrets. People who pursues science are wise and rational. Their pursuit of science may be their hobby! To start with, for scientists, the pursuit of science can bring many pleasures to their lives. Scientific research is their source of happiness. Next, the discovery of the new mysteries of nature is their greatest encouragement. Last but not least, only by pursuing a scientific career all their life can they maximize their own value. Of course, it’s impossible to cost nothing to reach the truth. For example, the cost of much time will make them tired, and their health may be influenced because of the high-powered job. What’s more, hair loss has also become an intractable problem for many researchers. However, those who regard pursuing the scientific career as the only thing they will do in their life should get the respect from all of us.
