【正确答案】[范文]
   As is shown in the table that the number of students choosing cross-campus elective courses has risen sharply during the seven-year period from 2005 to 2012. The number of students selecting Law, Finance and Business Administration doubled, and the number of students choosing Japanese enjoyed a minor increase from 14 to 23.
   Two reasons could account for it. Firstly, university students are increasingly aware that they should strengthen their competitive advantages. Secondly, with the job market growing more crowded, more students choose some practical courses so as to meet the demands of social development.
   However, there are problems in this aspect. For one thing, there may be a long distance between the universities offering elective courses and the Alma Mater. The tiring journey lays a heavy burden on students' body, thus affects their study. For another, the elective courses are always in the form of lectures, which will hardly develop students' practical abilities.

【答案解析】 这是典型的图表型作文。该图表显示2005到2012年间法学、金融学、工商管理和日语的跨校选修学生人数都有不同程度的增长，其中前三门课程的选修人数均翻了一番还多。可联系大学生就业难问题分析导致此种变化的原因。根据题目要求，文章结构可安排如下：
   第一段简要描述图表：总结趋势、引用数据(数据细节不必面面俱到)。
   第二段分析跨校选修人数发生此种变化的原因：大学生越来越意识到增强自身竞争力的重要性；顺应人才市场的需求，实用性课程备受欢迎。
   第三段分析目前的困难：校间距离太远，长途奔波影响学习效果；跨校选修以授课形式为主，学生在相关领域的实践能力仍然难以得到提高。
