Kids usually have a pretty good idea of what they want to be in the future.But they don\'t have right and clear ideas about their dream jobs. Scientists do some tests on hundreds of kids between the ages of 5 and 12.The results(结果)are interesting.Here is an example. Danielle and Francisco are both 7 years old.They live in Newark,America.And they are both in the second grade.When Danielle grows up,she wants to be a dancer.She thinks she can only earn(挣得,赚得)$505 a year.Francisco wants to be a cook.He thinks he can earn more than $500,000 a year. These show that kids have no idea how much money they can get from these jobs.Other results also show that kids don\'t know what they need to do to get their dream jobs.Some kids even want to be superheroes(超级英雄)when they grow up.But people can only find this job in movies and TV programs.
