No one can deny that English is now a global language especially in this internationalization. Most people around the world know and speak English everyday. English is spoken as the first language in many countries and used in various aspects of life such as: economy, culture, politic, finance, etc. In diplomatic relation among nations in the world, English is primary language. Therefore, it is easy to understand why most economical, cultural, financial associations have English name; also why all enterprises, companies require their employees’ foreign languages especially English. Hence, teaching and studying English are very necessary. And the reality solves this. English becomes one of main subjects in almost schools in the world. So does it in Vietnam. English has become one of compulsory subjects in all schools at different levels from primary schools, secondary schools to universities. It is not surprised if when a farmer can say “hello” or “thank you” to a foreigner. It means that we not only actively study English but also automatically absorb it.
