Text: WHO’S KILLING BRAZIL’S STREET CHILDREN?

Kids under 18 in Brazil…..........in numbers not found anywhere in the world apart from countries openly at war. Last year’s estimated 1.000 child killing actually represented an improvement: the average annual figure for the previous three years was more than 1.500. Brazilian’s horror has inspired the biggest surge of social activism since the 1970’s. But the killings continue. Wellington Barbosa never had a chance. The 14-year-old street kid was walking down a busy Rio de Janeiro avenue with his half-sister and her boyfriend one recent afternoon when a man with a green shirt shot to kill him.

Text: Several decades ago I absolutely detested grammar, English, and related subjects. As priorities go, this was at the very bottom of the list of subjects and, as one would expect, my grades reflected this preference. In later years, however, circumstances led me throughout 49 of our states and much of Western Europe. This exposure to various cultures, traditions, and languages has brought about a much greater appreciation of our languages and its evolution. I have almost become obsessed with this subject now and have collected quite a few texts on language and etymology, to say nothing of hundreds of articles clipped from papers and periodicals. The piece by Wen Smith, "It's Only Me", which appeared in the Sept./Oct. issue, is the type of article that turns me on, and it immediately became a piece of my collection. The author's excellent approach to the proper use of just a few words, enhanced by the artwork, almost makes this a classic work by itself. I hope that this will become the first of many such articles, for it can only serve to increase the interest and understanding of our rich linguistic heritage for thousands of your readers.
