I'll answer the question of my friends that why do I always use English either in Twitter or in blog even in daily life. Personally I think that English is the world's most important languange, why do I say that ?
First, English is international languange right. It's spoken by many people all over the world, either as a first or second languange. Second, English is often used in many activities both formal and informal. English is also the key, which open the doors to scientific and technical knowledge, which is needed for the economic and political development of many countries in the world. Third, English is a top requirement of those seeking jobs. Applicant who master eithert active or passive English are more favorable than those who don't.
From the facts above, it's obvious that everybody needs to learn English to greet the global era.
