【正确答案】[范文]
   
   Over the past decade, an increasing number of people have been in a hot pursuit of all sorts of certificates through taking countless exams.
   When asked, they would claim a wide variety of purposes. An overwhelming majority of college students take certain exams such as CET because their peers do so or their colleges require so. If they don't have such a certificate, they will be on the disadvantageous side. Some newly-graduated degree holders seek some career-related certificates in hopes of getting more job opportunities. But there are people who are crazy for any certificate that is in fashion just for its own sake.
   In my point of view, to some extent, certificates can reflect a person's basic quality in relevant fields, but it doesn't mean the more certificates one holds, the abler he or she is. It is particularly insensible to plunge into the certificate craze. As one's energy is limited, it is more advisable to focus on one's own specialty and get adequate qualifications in it first.
