【正确答案】[范文]
   For many university graduates, it is usually the case that they need to find a job after graduation though starting a career is challenging. And I think the most significant challenges posed to them are as follows.
   The first challenge is the fierce competition graduates have to face in the job market. As China has witnessed a growing number of university graduates every year, the job market is flooded with candidates looking for jobs. New graduates must outperform their competitors to seize employment opportunities. The second challenge is the transition from student to employee, which may turn out to be a difficult adjustment. When a graduate begins to work, he needs to take more initiative to complete tasks, make plans and explore new fields. And the effort he takes is closely related to how others evaluate his work.
   To sum up, graduates will face numerous challenges when starting a career. Among all challenges, the rat race and the transition of social roles are the most tough ones.

【答案解析】 题目要求考生就“毕业后开启职业生涯的挑战”写一篇短文。根据题目要求，文章内容可安排如下：
   第一段：介绍大学毕业生求职背景，引出职场挑战这一话题。
   第二段：主体部分，说明毕业生进入职场的两大挑战。第一个挑战是求职竞争激烈；第二个挑战是从学生到职员的角色转变。每个挑战后用一两句话具体解释，用以支持论点。
   第三段：总结全文。
   尽管开启职业生涯充满挑战，但很多大学毕业生往往都需要在毕业后找一份工作。在我看来，他们将面临以下重大挑战。
   第一个挑战是毕业生面临就业市场的激烈竞争。中国每年大学毕业生的数量一直在上升，求职者充斥就业市场。刚毕业的学生必须表现得比其他人优秀，才能得到就业的机会。第二个挑战是从学生到员工的转变，这样的调整可能并不容易。毕业生参加工作后，需要更加主动完成任务，制定计划并探索新的领域。他所付出的努力与其他人给予的工作评价密切相关。
   总而言之，我认为毕业生在开始职业生涯时将会面临无数的挑战。在所有挑战中，最艰巨的要数激烈的竞争和社会角色的转变。
