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