     This Thursday, across the US, kids are skipping school (缺课) and going to work with their parents.

They'll be making copies, sending faxes (传真) and sweeping floors. This is because April 28 is Take Our

Sons and Daughters to Work Day all over the US. This holiday shows kids what it means to be a grown-up

in the working world.

      I still remember when this day started, I was very happy. Not only did I have the chance to miss school,

but I also got to sit in my dad's taxi all day long and we would go to a restaurant for lunch.

     But after only 20 minutes of driving around the city. I was very bored. I couldn't read my book in the car

as I would get carsick(晕车)and my dad didn't like to turn on the radio. I got hot and uncomfortable. people

wouldn't get into his taxi because they thought he already had a passenger: me-so nothing happened. It seemed

years before we went out for lunch. I actually started to miss school.

     While the point of the day is to give kids a chance to experience real-life jobs and give them an idea of the

possibilities (可能性) for their futures, I got something completely different from the day. I learned to

appreciate (重视) school. Where else do you get to play with your friends, do science experiments, read great

books and write stories all in one day?

     Just as you'll have to learn to love your job later in life, learn to love school now. If you don't already, try

spending the day at work with your dad.
