　　留学对年轻人来说具有很大的吸引力。留学确实是一种崭新的经历，给我们提供了发现新事物的机会。但是我们也必须对可能会面临的问题有所思想准备。由于社会制度、信仰、价值观以及生活方式的不同，我们可能会受到文化震荡的困绕，难以适应新的环境。

　　我们通常要经历四个阶段才能习惯新的地方。这四个阶段是：蜜月阶段，危机阶段，调整阶段以及适应阶段。刚到国外的时候，我们会感到很兴奋，一切事情看起来都很奇妙。可是进入第二阶段以后，开始觉得事情并非原来想的那样好，我们就开始想家，并且有想放弃的危险。不过，只要我们坚持下去，就会克服这种震荡，适应并最终得益于这种新的文化。

　　Studying abroad greatly appeals to young people. It is really a brand-new experience which provides us with the opportunities to discover new things.

On arriving in a foreign country，we may feel very excited，and everything appears wonderful. But when we enter the second stage，we feel that things are not so good as we have expected. We begin to miss our homes and tend to give it up. However，as long as we stick with it，we can overcome this culture shock，be adapted to and finally get benefit from this new culture.
