Hi Jun Xie, Yeh Kayleigh's answer makes sense. None is better anyways. They are almost the same with some differences when it comes to vocabulary and expressions,while characterized by distinguishable accents. Even as she mentioned in England you will not find a standard British English . So you just decide to learn the one that appeals to you and you would be able to comprehend the other accents. If you happened to live in the States you might pick up their accent and modes of expression after a while ,if in England , Australia or New Zea land the same is likely to happen. So 加油 whatever you go for ;)

BRITISH ENGLISH :D Only joking! It really depends on what you want to do with your English. For example, if you use English for work and your company has important contracts in America, it will be better that you learn American English because it will be easier to tune in to their accent and vice versa. Better still would be to have a variety of teachers with a variety of accents. For example, if you go to live in London you may find it difficult to understand some people anyway, because we have so many different nationalities, each with their own unique accent. Indian English, South African English, Australian English, American English, Scottish English, Irish English... Also there is a lot of variety within each accent - for example the Californian dialect/accent is very different from the Texas dialect/accent etc. At my school, we have mainly Brasilians teaching English, an American and myself (British). The American girl and I often ask each other questions about words we haven't heard before (for example, we don't have "street luge" in England and I didn't know what it was!). Very interesting! But if you have a mixture of teachers, you will maximise your vocabulary and be used to speaking to anyone :)

Hi Jun Xie. It is up to the individual whether you like to study American or British English. Also it depends on the availability of native English speaking teachers in your area and what course your teacher is following. Here's a good site that has listings for both dialects: http://www.uta.fi/FAST/US1/REF/usgbdiff.html#b2a
