18．English is the first language of several countries．However，it has many differences．British，American，and south African English are all spoken differently．In many English Language courses，the British and American different are taught．One is not more correct than the other，but there are important differences between the two．
Probably the biggest difference between American and British English is the vocabulary．Different words and expressions are used to talk about the same thing．For example，in the United States，people
throw their garbage into the trash can．In England，people throw their rubbish into the dustbin．In Britian，people take a lift to the fifth floor．In America，people take an elevator．
American and British grammar can be also different．For example，speakers of British English will
ask，what did you do at the weekend，but Americans usually say"on the weekend"．In the United States
people usually say"I have gotten a new car．"，but in the UK，they will say"I have just got a new car．"
The pronunciation in American and British English is also different，and even when the spelling is the
same．The word"tomato"---pronounced"to-mah-to"in British English--is a classic example of this．
Vocabulary，grammar and pronunciation are three ways English is different in different parts of the
world．Learning all this is not easy，so English learners should just know that they are always there．
