参考词汇：开拓视野 widen one’s vision 语言障碍language barrier
Attending schools abroad has many advantages. Firstly, by looking at our own country from outside, we can widen our vision and broaden our minds. Secondly, we can visit famous scenic spots and make friends with the local people. Thirdly, we can use the foreign language in our daily life so that our ability in the second language may be improved quickly.
However, there are also some disadvantages in attending a foreign school. The most serious problem is the language barrier. Most students do not have adequate knowledge of the language spoken there. On arriving there, they find it difficult to understand what the teachers are saying. Furthermore, the cost of living is much higher than that in our country, so most students have to find part-time jobs to support themselves. Faced with these difficulties, many students find themselves unable to pay full attention to their studies and learn little.
On the whole, it is a good thing to study abroad. However, one must not lose sight of the disadvantages.
