When do you think you are an adult ? Maybe different 1have different ideas.
Now let's see what some American teenagers(青少年)say .
Sam: In 2idea ,you are an adult at the  3of 18. That's when you can vote(投票)。You can help to 4who rules(统治)the whole country .That's also a grown-up does! My grandfather couldn't vote 5he was 21.They changed（改变） it to 18 in 1971.
Jenny：I don't 6 it's hard to say . I can drive a car at 16, can't I ?When you have a driver's licence , you can 7it to people to tell them your age for all kinds of things .8  sixteen must be the age when you change from a 9person to an adult.Because you can tell others you are not a 10 any more .
Suzie : Well , I think there is 11 wrong with American laws for when young people can12 things . I can vote at 18 and drive at 16. So you would think 18 is a grown-up, 1316 isn't .But then I can't drink wine（酒）until I'm 21 ! If I'm14  an adult at 18, how can people stop me from 15 a cup of beer in a bar ?
