Learning English language.

To my mind today English is the language of the world.
In a new millennium English inevitably will be a language of the world. More than 600 million people speak English as their first or second language.
Over 350 million people speak it as a mother tongue. The native speakers of English live in Great Britain, the United States of America, Australia and New Zealand.
English is the major international language for communication in such areas as science, technology, business and mass entertainment English is one of the official languages of different political organizations.
It is the language of the literature, education, modem music, international tourism.
As for me learning a foreign language is not an easy thing. It is a long and slow process that takes a lot of time and patience. After college I am going to continue my education and I understand that to know English is absolutely necessary for every educated person, for every good specialist of a new millennium
When learning a foreign language you learn the culture and history of the native speakers. A lot of my friends and me like English and use it for communication. English helps us with listening to music, reading, watching TV, exploring Internet
I am sure that English will be popular and necessary in a new millennium and will open new horizons and opportunities for us.
