W: Hi. John. I haven’t seen you for a few weeks.
M: Hi. Mary. I’ve been studying a lot for final exams.
W: Well, the term is almost over now.
M: Yeah. My brother is coming for a visit this summer, and we’d like to see some of the country. But traveling is so expensive.
W: Have you thought about camping
W: Camping I’ve never done that !
W: Oh. I think you’ll really like it. You can rent the equipment you need. It’s much cheaper than buying it or staying at a hotel.
M: What a good idea! We can drive until we find a nice spot and just camp wherever we like.
W: Well, not exactly. It’s usually illegal unless you camp in a designated area. But there are many national parks and camp grounds around the country.
M: But that takes all the fun out of it.
W: Not really. Besides, there are almost always conveniences like showers at camp grounds to make it a little easier. It’s a good way to make new friends, too.
M: Sounds great! Here’s my bus. I’ll talk you about this again and get all the details.
A．Students.
B．Teachers.
C．Park employees.
