Studying Abroad

In recent years, studying abroad has been popular. Tens of thousands of Chinese students have gone to foreign countries to study. Many people are trying their best to apply to go abroad.

There are many advantages in attending schools abroad. First, students who have studies abroad can act as mediators between people of different cultures. Second, we can learn much more advanced knowledge of science and technology from foreign countries. Third, we can learn foreign languages more quickly.

However, there are some disadvantages. Most of the students are too young to live alone without any living experience. Besides, being far away from their home country, they may feel lonely and homesick. Of course the costs are much higher there than at home.

In my opinion advantages are more than disadvantages. So it is a good idea to attend schools abroad.
