Choose the best answer from the four choices marked A, B, C, and D. If you don't have much money, what are some cheap ways to travel? In fact, there are a few "almost free" ways to travel. One is to drive a car for a car-moving company. When people move from one part of the country to another, they often need to move their cars, but they don't want to drive them themselves. They pay a car-moving company to do this for them. Some of these companies hire people to drive the cars. The drivers usually have to make a deposit (押金)and pay for petrol, but this is a great way to travel if you can find a car going your way. A bigger problem is how to get back home! How about a free plane ride? If you can fly with almost no advance notice, you can be a courier (信差)for a mailing company. A courier delivers mail in a hurry. The company may buy you a round-trip plane ticket if you deliver a package for them. There are even companies that need to make large mailings internationally. Because it's so expensive to send international mail, these companies pay for someone to fly overseas with boxes of letters for their offices or customers in other countries. The way to travel "completely free" by air is ____.
