English is no longer the language of the English alone; it is an international language. It is difficult, sometimes impossible, to do without English. Pilots fly over and land in, many countries. They have to use English everywhere. Officers at the airport and tourist guides at different places must know English to communicate with people. People working at hotels cannot but use English with tourists from different countries. Postmen must know English, for addresses on envelopes from abroad are all written in the language. Telephone operators use English to make or receive calls. Books for mechanics also are mostly in English. Persons going abroad find the language very useful to communicate or study. It is, therefore, necessary that we should learn English.
