one car.
M:That's a good idea.How do you join carpooling?
W:Well,there is a special phone number you can call.You leave
a message with your address and phone number,and then
someone calls you back with the names and phone numbers of
the other people in your area who want to carpool.
M:How do you know so much about this?
W:I called the number for the first time about five years ago.
Carpooling is a great way to go to work.I've already got a
ride for tomorrow.
M:I'm going to do that tomorrow,too.I don't want to be the
driver.
