One billion people trying to conjugate verbs. One billion people trying to understand the difference between much and many. Yes, that's right, one billion people trying to learn English.
This is because English has become the most important language in the world. 1.5 billion people already speak the language in addition to the 1 billion that are learning it.
Most major world organizations and functions are administered in English, including the United Nations, Olympics, and others. Most international business is in English, and the language is often used between people form different nations. English is the international language. As the world becomes smaller there will soon be no way to avoid English. So why not learn it now?
