【答案解析】[范文]
   
   Sitting exams to grab various qualification has become heated in current society.
   Juniors and seniors in college are often found on campus with thick textbooks under their arms or off campus taking exam preparation classes. And now the trend even seems to have influenced sophomores and freshmen.
   Taking a closer look at this fervor, we will find that people are crazy about certificates with different purposes. At least they fall into two categories: those who know exactly what they want and how they can get it, and those who obtain a lot of certificates in a variety of fields simply because they believe more certificates are better than none, or because their classmates all attend those exams. While the latter follow suit, the former perceive crystal clear that qualification certificates, which represent one's practical skills in a certain realm, are highly valued in job interviews, especially when they are hunting for a job that needs exactly that skill represented.
   In my view, both of them might achieve some success for they indeed both strive for an extra goal besides getting a university degree, but the former would probably taste the sweetness of success much sooner than the latter.
