decades linguists have been channeling their energy (-ies) into
creating a language of international communication. Many scientists and
entrepreneurs (business people) wish there were / was a single
universal language in the world. Esperanto is considered to have been
the most successful artificial language. If Esperanto had been
recognized at least in several European countries, it could have long
turned into (become) a language of international communication.
However, for a variety of reasons it didn’t happen (it never happened).
If anyone had said in 1950 that (the) English (language) could become
global, they would have been laughed at. But it’s no small accident
that by the end of the 20th century English had become dominant in
political, economic and cultural life of the countries that had never
depended on (had never been dependent on) Britain economically or
politically. Being at the cutting edge of economic development the USA
couldn’t fail to promote the spread of English all over the world.
Although globalization and the rapid development of communications and
information technologies are turning our planet into a new Babylon, we
are unlikely to speak a universal language in the near future. IV. 1 – b; 2 – c; 3 – d; 4 – c; 5 – a; 6 – b; 7 – b; 8 – b; 9 – b; 10 – a
