议论文
议论文是通过对某种现象或观点的评述，要求作者通过摆事实、讲道理、辩是非 确定其观点的正确或错误。同时必须做到逻辑严密，结构清晰，语言精炼。议论文的写作往往从正反两方面来论述，且都有其约定俗成的议论模式，即从“主题句—正面议论—反面议论—结论”四大块去营造文章的基本结构。词汇运用多用书面语，少用口头语。在句子间使用连接词，能使文章脉络更加清晰，逻辑关系更加流畅。如： to begin with，on the contrary，also，additionally，furthermore，as well，last but not least，worse still，in short，all in all，as a result，in my opinion，as we all know等等。

Studying abroad
In recent years，studying abroad has been popular.According to the media，besides college students，more and more middle school students are studying abroad.
Studying abroad has its advantages.Students can learn a foreign language better and easily in a situation that can not be found at home.They can broaden their mind and learn a lot more，including advanced technology.People from different cultures can have more chances to learn from each other.
It has disadantages，however.Teenagers are too young to look after themselves.They may feel lonely and homesick，which may have a bad effect on their characters.And the cost is too high.
In my opinion，whether a student should study abroad depends on his or her ability and the family economy.
