D
In the USA, many children need a carpool. A carpool is right for children who live far away from school and have no chance to take school buses.
Parents are often busy and they don't have enough time to take their children to school in a car every day. So they think of a new idea. They use a carpool. That means a group of students share a car to school. There are usually four or five kids in a carpool. Their parents take turns(轮流) taking the kids to school in their cars.
Getting to school in a carpool is useful for parents and students. Students can get to school easily if they choose to go in a carpool. And it can help their parents save(节省) a lot of money.
Teamwork is really important in the carpool because no one wants to make the others late for class. If you sit in the car and wait for a classmate for a long
time, you may get a little angry(生气). But your carpool friends might feel the same way when you keep them waiting.
It's a great lesson in responsibility(责任) that you learn before school ever starts—in the carpool.
