When your school doesn’t have a bus, and you live too far away to walk? How do you go to school?  “Let’s carpool! ”most US middle school students will get that cool idea. Carpooling is a group of people sharing the responsibility(責(zé)任) of driving to school in the morning. There are usually four or five kids in a carpool and their parents take turns driving the kids in their cars.It might be the kids’ first experience with real teamwork. Teamwork is really important in the carpool because nobody wants to make everyone else late. It’s a great lesson in resposibility.

Carpooling is coming into fashion everywhere now. You can find lots of informations of carpooling on the internet. Carpooling is cool! Why?
It’s good for the environment. In today’s culture of everyone needing to try their best to protect our environment, carpooling is one of the best ways. By taking 3 cars off the road, the pollution can be cut a little. Take that over a town, a city, a state, a country and think about how much less pollution is going to be in the air over the course of even one year.
Gas(汽油) now is much more expensive than it used to and if you need to watch the cents(美分), then it’s possible that carpooling could be the answer to your prayers. Even if you have to use your car once a week instead of two, that’s one round trip of gas you’re saving. So carpooling helps you save money.
Carpooling is a great way of getting to know people better. If you’re carpooling grade school kids, then you’ll find that slowly you’ll get to know your child’s peers(同齡人) and friends better. It's a great opportunity to meet people while saving the environment and your money.
