【正文】 f Munich, wanted to discover whether accent (口音 ) changers 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 upperclass 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 hears saying ?thet men in the bleck het‘. Now it would be ?that man in the black hat‘. 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. Each Christmas, the 10minute broadcast is put on TV at 3 pm in Britain as many families are recovering from their traditional turkey lunch. (傳統(tǒng)火雞午餐 ).

C Do you know of anyone who uses the truth to deceive (欺騙 )? When someone tells you something that is true, but leaves out important in formation that should be included, he can give you a false picture. For example, some might say, ―I just won a hundred dollars on the lottery (彩票 ). It was great. I took that dollar ticket back to the store and turned it in for on e hundred dollars!‖ This guy‘s a winner, right? Maybe, maybe not. We then discover that he bought $200 worth of tickets, and only on e was a winner. He‘s really a big loser! He didn‘t say anything that was false, but he left out important information on purpose. That‘s called a halftruth. Halftruths are not technically lies, but they are just as dishonest. Some politicians often use this trick. Let‘s say that during Governor Smith‘s last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents(對手 ) says, ―During Governor Smith‘s term, the state lost one million jobs!‖ that‘s true. However, and honest statement would have been, ―During Governor Smith‘s term, the state had a gain of two million jobs.‖ Advertisers(廣告商 ) will sometimes use halftruths. It‘s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, ―Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.‖ It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company. This kind of deception happens too of often. It‘s a sad fact of life: Lies are lies, and sometimes the truth can lie as well. 49. How much did the lottery winner lose? A. One hundred dollars. B.

D Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers. Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present. The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. ―While coughing is not necessarily harmful(有害的 ) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,‖ said Professor Peter Barnes. Ten healthy volunteers(志愿者 ) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers no
