M: Hey, Linda! Long time no see! I heard that you’re going on a boat trip this afternoon.
W: Yes, I am, and I can’t wait! I’ve never been up close to a whale before. Do you think we’ll see many whales today? Cindy told me she didn’t see anything last time, so I think it really depends on luck. What would you say?
M: Well, I think we should have better luck, because this is the best time of the year to see whales.
W: [14] Why is winter the best time of the year to see whales?
M: At this time of the year, the whales are heading south from Alaska to warmer water for the winter. Then they’ll return to Alaska before summer.
W: So we can see lots of whales busy traveling at this particular point. By the way, do you know how long the boat trip is? Cindy said it was like quite a long day, and I think it was probably because she didn’t see anything.
M: The boat leaves at one o’clock and returns at about three o’clock. So you may want to get to the fisherman’s wharf before one.
W: Only a two-hour trip?
M: Yes, the whale-watching travel is pretty close to shore, so we don’t need to go out very far in the ocean to see them.
W: I guess two hours is probably enough. I’ve never actually been out on the ocean in a boat, and I’m not really sure I’ll like it. OK, then, I will see you this afternoon!
