Example 2：Scientists explore the unknown field of science passionately（热情地）and persistently（坚持不懈地）which leads to the improvement of our society. So they always gain the respect and admiration of people around. A good scientist is not only a man of considerable intellect but also a person who is hard-working, devoted（专心致志的）and persistent.

Most successful scientists say that there is no golden path but a bumpy road leading to their success. That is hard work. They persist（坚持）in their exploration in science and perform their experiments over and over again no matter how boring they are and how many times they have failed.

When good scientists get down to（开始）their work, they devote themselves into it entirely and hardly waste any time. Some of them even forget to have meals and sleep. They work efficiently, which leads to better quality of work.

In addition, persistence is necessary for success. If we study or work day and night, but nothing achieved, we may be restless（焦躁不安的）and want to give up. So we may say that a scientist can achieve nothing if he doesn't have the spirit of persistence.

All in all, good scientists have many great qualities and they never give up easily.

Brief Comment: Example 1的回答比较简单，重点分析了科学家所具备的三个素质，即好奇心、决心和耐力等，成功需要1%的灵感和99%的汗水; Example 2的回答比较深刻，且用词丰富得当。科学的道路是不平坦的，因此每一位科学家都是辛勤耕作，用汗水浇开了胜利之花。
