阅读理解 The Queen's English is now sounding less upper-class, a scientific study of the Queen's Christmas broadcasts had found.Researchers have studied each of her messages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received. Jonathan Harrington, a professor at Germany's University of Munich , wanted  to  discover whether accent (口音 ) changes  recorded over the past half century would take place within one person. 'As far as I know,there just is nobody else for whom there is this sort of broadcast records, ' he said. He said  the  noble  way  of  pronouncing  vowels (元音 ) had gradually lost ground as the noble upper-class accent over the past years. 'Her accent sounds slightly less noble than it did 50 years ago. But these are very, very small and slow changes that we don't notice from year to year. ' We may be able to relate it to changes in the social classes, ' he told The Daily Telegraph, a British newspaper. 'In 1952 she would have been heard saying  'that men in the black hat ' . Now it would be ' that man in the black hat ' . Similarly, she would have spoken of ' the  citay ' and  ' dutay ' , rather than ' citee ' and ' dutee '  , and  ' hame '  rather than  'home'. In the 1950s she would have been 'lorst', but by the  1970s  'lost'.' The Queen's broadcast is a personal message to the Commonwealth countries.
