Trev, Paul and Wei discuss how to get from New Orleans to Orlando Trev: I think we should fly. It's the fastest option. Wei: But if we fly, we'll miss out on the landscape. Trev: Airplanes are out, then. We've already rented a car. How about hitchhiking? Wei: That sounds dangerous. I'll pass. Trev: The only other options are the train or a bus. Wei: I'd like to see what an American bus is like. Trev: They're not as nice as trains. Wei: But Greyhound is famous. Let's take it. Trev: OK. Let's go find a computer to buy e-tickets.

1）当let后只有一个单音节动词，变被动语态时，可用不带to 的不定式。 They let the strange go.---> The strange was let go.
