Переведите текст (не через переводчик)

language is the means of communication. The most common way of expressing an idea for people is to say л out loud, language enables people to understand each other. At the same moment language can be a major barrier to understanding because there are thousands of different languages on our planet. From the earliest time, with the development of trade and exchange of ideas and techniques people saw the necessity of learning foreign languages.
A language that is used as a means of communication by people of different nations is called international, international language helps people of different nations understand each other.
it should be said that not all the languages had equal importance in different centuries in the world Preference was given to that one which country was more powerful at that time. In the 15lfl and 16 centuries Spain was in the vanguard of European and world expansion and the Spanish language could be heard in the far reaches of our planet. French became the dominant language of the Western world in the 17 and 19th centuries. In the 19th century French was the official language of our country Since childhood Russian aristocrats were learning French. For example Pushkin wrote his first poem in French Russian was spoken only by common people. In the first half of the 20th century, during the period between two World Wars, English started gradually to replace French as the international language
The transition from French to English as the international language was relatively easy because in many countries of the world people already knew English by that time. The British Empire brought English not only in North America, but in Australia, Africa and India, as well. The leadership of English in the modern world can be explained by numerous factors. Over 300 million people who live in Great Britain, Australia, New Zealand and the USA speak English as a native language. English is one of the official languages in the Irish Republic, Canada, the South African Republic. It is also the second official language used in the former British and US colonies. English is one of the official languages of the United Nations Organisation. It is the language of literature, education, modern music, international tourism.
The dominance of English in the contemporary world is explained by the appearance of lots of people who want to /earn English not for pleasure or prestige but because English has become the key to international scientific, technological and commercial innovations of today.
The problem of learning languages is very important today. Foreign languages are socially demanded especially at the present time when the progress in science and technology has led to the explosion of cnowledge. English is needed as the main and the most efficient means of information exchange. Young »eople around the world need English to use the Internet, communicate, understand films, songs, read ooks and magazines in the original.
issia is integrating into the world community and the problem of learning English for the purpose of mmunication is especially urgent today. In Russia people learn English to be able to exchange the ?sr information in science, technology, commerce and tourism.
