题型:问答题 简答题 Cloze. The British love to think of themselves as polite, and everyone knows how fond they are of their "pleases" and "thank you". Even the simplest business such as buying a train ticket requires 1 seven or eight of these. Another 2 of our good manners is the queue. New-comers to Britain could be forgiven for thinking that queuing rather than football was the 3 national sport. Finally, of course, motorists generally stop at crossings. But does all this mean that the British should consider themselves more polite than their European neighbours?I think not. Take forms of address (称呼) for example. The average English person- 4 he happens to work in a hotel or department store-would rather die than call a stranger "Sir" or "Madam". Yet in some European countries thisis the most basic of common address. Our 5 "you" for everyone may appear more democratic, but it means that we are forced to seek out complicated ways to express 6 . I am all for returning to the use of "thee" and"thou" (Thee and thou are old-fashioned poetic words for "you"); "you" would be 7 for strangers andprofessional relationships. And of course, the English find touching and other shows of friendship truly terrifying. Have you noticed how the British 8 ever touch? Personally, I find the Latin habit of shaking hands or a friendly kiss quite charming. Try kissing the average English person, and they will either take two steps backwards in horror ; or, if their escape is 9 , you will find your lips touching the back of their head. Now what could be 10 than that?
