    Some children cannot wait to grow up.Because once you become an adult you are free to make your own decisions.More importantly you can do all those things that you cannot do now because you are too young.So the question is 'At what age do you really become an adult？' Well ，people become adults at different ages in different places.

    In Australia the 18th birthday is a very important event for young Australians because it means they can do almost anything they want.They can vote （选举），learn to drive a car ，get married，join the army and even buy their own houses.Even if they can do all these things，most Australians have to wait until their 21st birthday to really celebrate becoming an adult.This is the traditional adult age in Australia and the USA and the UK.

    Even though 21 is the traditional adult age in many English﹣speaking countries the law nowadays is different in each country.In the UK you can join the army at 16 and even get married at 16 if your parents allow.Young people in the UK can learn to drive a car at 17，although they have to wait until they are 18 to vote.

    In China ，you can vote and learn to drive a car when you are 18，but if you want to get married，women have to wait until they are 18 and men until they are 22.Chinese people celebrate important birthdays every 10 years﹣﹣so when young people turn 20，they can expect a big party!

    No matter what age you are，becoming an adult is really about learning how to be independent and responsible（负责任的）.Once you are finally able to take care of yourselves and make your own decisions，then you can say that you are truly all grown﹣ups.
