     Many English learners have difficulty deciding what kind of English accent they want to have. A US

accent, perhaps modeled on the way a Hollywood star speaks? Or maybe you want to imitate (模仿) the

British accent of a BBC news reader?

     Young British people find the US accent attractive while young US people like a British accent. Especially

when the person speaking is of the opposite sex! Let's listen to what they have to say. Stephen Yang, 17, from

London, UK A US accent is cute, especially when a girl speaks it. Whether it's Jessia Alba speaking or the

girl- next-door, the way US girls speak has a sweet tingle that is really sassy (时髦). A girl from Texas recently moved into our neighborhood. Her Texan twang (鼻音) had all the boys here on their knees within seconds of

meeting her.

      To me, accents reflect the attitudes, characteristics and lifestyles of the people. Jennifer Sun, 16, from

New Jersey, US From watching English actors like Daniel Radcliffe, my friends and I have developed a soft

spot for British men. Some are attracted to the qualities of English males, while others admire their sense of

style.

     Everyone, however, agrees that the most appealing aspect of an English man is his accent. For example,

many American girls watch Harry Potter movies over and over again just to listen to the actors speak. The

English accent seems almost like art.
