There is an unusual holiday in the US that falls on the fourth Thursday of April every year．It is very different from Christmas，Thanks giving，or other well-known holidays．It is called Take Our Daughters and Sons to Work Day．This holiday is meant to be educational as well as fun．The ideais simple，andthenamesaysital．It is a day for working parents to show their kids what they do all day．
Although this holiday doesn’t seem very complex（复杂的），it has meaningful purposes．There are manygood reasons why a child should know what his or her parents do at work．For one thing，it is hard for children to understand the life of an adult when all they know is school．Therefore，this holiday helps children learn what it means to have a job．It also helps them learn about the differences and similarities between their world and the grown-up world．When young people know more about their parents’lives，they can form stronger parent-child relationships．This alone is worth a day of celebration．
