We live in a global village that requires a language with a genuinely global status as a means of communication. During the twentieth century, English has clearly emerged as the lingua franca owing to both past British political imperialism and the more recent superpower status of the United States. Further contributing to world domination of the English language is the fact that the computer and Internet sprang from the US. Whether you like it or not, you are destined to learn English at least to some extent in order to live in this global village. For the last two decades, one of the most mistaken ideas a number of Korean English teachers have had is that speaking and listening are the primary forms of language, while reading and writing are secondary. In fact, reading is regarded as a skill of much consequence to us since it provides us with access to a huge quantity of information on the Internet, of which at least 80% is written in English. Writing, too, deserves a great deal of attention because we are increasingly called upon to use standard English expressions. As diligent learners of English, we had better not forget the place accorded to language not only as a medium for exchange and constructing information but as a tool for thinking. So we should try to think in English to the point where we have thinking-in-English as a habit, thereby leading to increased familiarity with the language. Such familiarity entails, above all, possessing a command of English.
