First of all, the cost of studying abroad is expensive.

首先，出国留学的费用是昂贵的。

Specifically, these people have to spend a lot of money on tuition and living expenses, which not everyone can afford.

具体来说，这些人不得不花费一大笔钱在学岩昌大费和生活费上，而这并不是每个人都负担得起的。

In addition, for those students who lack the ability to live independently, studying abroad is a great challenge.

此外，对于那些缺乏独立生活能力的粗竖学生来说，出国留学是一个巨大迅和的挑战。

If they can't take good care of themselves, their academic achievements will be affected to a great extent.

如果他们不能照顾好自己，他们的学习成绩将在很大程度上受到影响。

Last but not least, studying abroad may have a negative impact on students' psychology.

最后但并非最不重要，出国留学可能会对学生的心理产生负面影响。

With the rapid development of society, we have entered an era of information explosion. In order to acquire more knowledge, more and more people decide to further their study abroad. Studying abroad brings about many advantages. It widen students’ knowledge and horizons, and meanwhile cultivates their independence and personalities.

Firstly, students can learn advanced knowledge and experience abroad. Since the reform and the policy of opening to the outside world, China has strengthened cooperation with many companies. As a result, the scientific and technological level has been improved very rapidly. However, compared with the developed countries in the world, we still have a very long way to go. Studying abroad provides opportunities to students, who can learn advanced knowledge and management experience, so as to enhance the scientific level in our country.

Secondly, studying abroad can cultivate students’ ability to live independently and their characters. Students have to deal with many problems when they study abroad. They have to learn how to be accustomed to a new environment and how to get along with the teachers and classmates. During their study, they can acquire some interpersonal skills.

Finally, studying abroad can provide a good language environment to students and make it easy to pick up a language. Foreign language is a tool employed to communicate with each other. It can remove language barrier and make international cooperation much easier.

However, “Every coin has its two sides”. Studying abroad also brings about many disadvantages. Firstly, students will be confronted with so many psychological problems. They often feel lonely and helpless in a new environment. Furthermore, the tuition is very high, which is a very heavy financial burden to the average people.

To sum up, the advantages of studying abroad outweigh the disadvantages greatly. We encourage students to study abroad. When they accomplish their curriculum, they can make more contributions to the construction of our society.
