     It is sometimes said that English is English and that there are no differences between different kinds of

English, but this is not the case. American English is in general quite different from UK English. The main

differences relate to the use of certain words and to spelling. American English is much more phonetic(与发音近似的)than UK English and in American English a 'z' or a 'c' is often used where an 's' would be

used in British English.

     Words can vary in different types of English as well. An "estate agent" in UK English is someone who

works in "real estate" in American English. British people talk of "rubbish" while the Americans call this

"garbage". The UK people have "bins", but the Americans have "dumpsters".

     The differences between these ways of using English make translating works into English a difficult

business. There are translation tools available on the Internet, but these can often translate words in a very direct way and the end result is a sentence that has lost its meaning.

    The best way of translating any written piece of work into the English language is to first decide what

kind of English you want the piece to be translated into. For example, if it is for a British market, then use

the UK English. For the best result, always use some kind of spelling and grammar checker so you can

make sure that you are using the proper terms, spelling and vocabulary.
