分两方面看,一方面到国外可以多了解外部世界,开拓自己的视野,丰富自己的阅历,有助于自身成长,可能有利于将来就业；另一方面,去国外学习要花费很多金钱,可能会给家长带来很大负担,而且等毕业后可能由于长期在国外而丧失了很多机会.能用英语表达一下，给我参考As an old saying goes"Each coin has two sides",going abroad to study also has advantages and diaadvantages.On one side,when we study abroad,wo can know more about the world out of our country.We can widen our sight ang enrich our experience,which is helpful to our growth.And we can own advantages in finding work.On the other side,going abroad to study may need a lot of money,which will bring great burden to our parents.What's more,wo may miss so many chances when wo study abroad.这是大致内容，具体的你再加点内容吧，相信你!
