Sample Essay

Studying abroad has become increasingly common in the last few years, many students and their families clearly consider the experience worth the sacrifices involved. It means one has to give up friendships when he or she moves abroad and often use life savings. Moreover, many governments are willing to invest huge sums of money in sponsoring their young people to study in universities overseas.

However, this trend has drawbacks as well as benefits for those concerned. One potential drawback is that the instruction international students receive may not be relevant to their home contexts. For example, students from developing countries who go to Western countries for teacher training are often taught to use teaching techniques that are suitable for small classes. When they return home they are often expected to teach classes of 40 or 50 students. Hence, what they have been trained to do may not be relevant.

Another potential drawback is the phenomenon of 'brain drain'. Prior to leaving home, they may be fully committed to returning. Nevertheless, students are often at the stage in their lives when they are forming their most important personal and professional relationships. Thus they may choose to remain in the host country on completing their studies.

However, most international students find ways of making the experience work well for themselves and others involved. Most return home, enriched by new friendships made abroad. Furthermore, most find ways of adapting what they have learned to their home context. On balance, the drawbacks do not outweigh the benefits.

在过去的几年中，出国留学变得越来越普遍，许多学生及其家人显然认为值得付出牺牲的经历。这意味着当他或她出国时必须放弃友谊，并经常使用积蓄。此外，许多政府愿意投入巨资赞助他们的年轻人去海外大学学习。

但是，这种趋势既有弊，也给有关方面带来好处。一个潜在的缺点是，国际学生接受的指导可能与他们的家庭环境无关。例如，来自发展中国家的学生到西方国家接受教师培训时，通常被教导使用适合小班教学的教学技术。当他们回到家中时，通常会教40至50名学生的课程。因此，他们的教学模式可能和国内并不相同。

另一个潜在的缺点是“人才外流”现象。在离开家之前，他们可能会完全致力于返回家园。然而，学生处于一个建立自己最重要的个人和专业关系的人生阶段。因此，他们可以选择在完成学业后留在东道国。

但是，大多数国际学生都找到了使体验对自己和其他参与人有效的方法。多数返回家乡，并因在国外结交的新友谊而更加丰富。此外，大多数人找到了使所学内容适应其家庭环境的方法。总而言之，弊端不会超过收益。
