English has become a world language because of its establishment as a mother tongue outside England,in all the continents of the world. This exporting of English began in the seventeenth century,with the first settlements in the United States,assisted by massive immigration in the nineteenth and twentieth centuries,that has given the English language its present standing in the world.

This is something that he cannot bring himself to talk about. “It all went wrong”, he whispers. He was silent for a minute; then recovered. He began to talk more loudly. “Look at me now it makes me angry. And what about the President? He’s been in power for years, and look what he’s done for us. Nothing! I’m still out on the streets and live the life of a tramp.” 39. It would appear that Thomas _________ A. has organized a protest recently. B. takes an interest in important events.
