Here is some more scenario,
English for News and Information
English is commonly used as a medium for the communication of information and news. Three quarters of all telex messages and telegrams are sent in English. Eighty percent of computer data are processed and stored in English. Much satellite communication is carried in English. Five thousand newspapers, more than half of the newspapers published in the world, are published in English. Even in many countries where English is a minority language, there is at least one newspaper in English. In India alone, there are three thousand magazines published in English. In many countries, television news is broadcast in English. Because of the power of television, demonstrators in every country use signs printed in English for the benefit of the international press.
English for Business, Diplomacy, and the Professions
English is a major language of international business, diplomacy, and science and the professions. It is the language that an Iranian businessman and a Japanese businessman are likely to use to communicate. Important commodities such as silver, tin, and hard currency are traded in English. English is also an official language, or the official language, of many international organizations, including the United Nations and many professional organizations. It is frequently the language of international conferences, and it is the language of international athletics. Throughout the world, many professional papers are published in English. Even papers that are published in other languages often have abstracts in English.
English for Entertainment
Popular culture has also played an important part in spreading English. American and British popular music are heard all over the world. American movies are seen in almost every country. Books in English are available even in countries where few people actually use English. One reason that students give for learning English is to understand these songs, movies and books.
English is also very important for international travel. Much of the information countries disseminate about themselves outside of their borders is in English. English is spoken in large hotels and tourist attractions, at airports, and in shops that tourists frequent. There are newspapers printed in English, and TV news is available in English. Tours are almost always available in English. Even in countries where few people speak English on the street, people who work with tourists generally speak English. In some countries even drivers of buses or streetcars and sellers at newsstands speak English well.
Other Uses of English
In many former British colonies, English is still used in government and as a medium of communication among people who do not have another language in common. In some cases, it is a neutral language that is used to avoid giving any one indigenous language too much prestige. English is often used in India, because it is neutral. It is the language of government. People who speak English have a certain status in society. It is used for books, music and dance. In Singapore, English is a second language, but it is necessary for daily life. Many companies there use English. In addition, sixteen countries in Africa have retained English as the language of government. Now standard English is taught in schools in those countries, because it is necessary for careers.
English is also studied as a foreign language in countries where it is not generally used as a medium of communication. In China, English language lessons are popular TV programs. Two hundred fifty million Chinese--more than the population of the US--are learning English on TV. English is usually the first or most commonly taught foreign language in many countries, and people understand it a little at least.
Conclusion
As we have seen, English is a widespread and important language in the world today. It is used for everything from international academic conferences to news reports to popular music lyrics. It is used not only for communication between native speakers and nonnative speakers of English but between nonnative speakers. Even though it does not have the greatest number of speakers in the world, it is the most widely used language in the world, and it will be used by more people in the future.
