Nowadays , more and more students go to foreign countries to study . many people are spare no effort in applying for going abroad .

About this phenomenon , different people have different points . some people agree with it . first of all , studying abroad is the best way to improve our language . if we want to break away from “ mute English ” , it’s a good method to help you . second , by studying abroad we can better to know foreign countries’ culture . going in a country and we can experience different culture’s charm . last but not least , it’s a good opportunity to travel , make friends with different people and broaden your horizon .

But others disagree with it . in the first few months these students will have a language barrier and hard to go in their society . many students can’t make a good programme when their parents aren’t with them , some of them spend their abroad’ time in vain .

As long as I’m concerned , if we have a chance to study abroad ,we should treasure make full use of it . it will make us be wiser . because of the study’s experience , I believe that our life will also be more beautiful and wonderful .

Truman's insight could well be applied to another,even more venerated Washington figure:the CEO-turned cabinet secretary.
