听力原文：M: So Rebecca, what did you do for spring break? W: I went to southern California. I was in Los Angeles and San Diego. Oh, and I stopped in San Juan Capistrano. That's south of Los Angeles and north of San Diego. I happened to be there just about the time the swallows returned. M: Oh, I've heard about that—they always return on the same day, don't they? W: That's right, on March 19th. And they always fly away on the same day, October 23rd. In the meantime, they migrate over 7,000 miles to get to their winter home. M: Seven thousand miles—imagine! And always coming back on the same day! W: Yes, except for one year, a long time ago-they were delayed for a day by a storm at sea. M: You sure were lucky to be there on the one day of the year when the swallows return. W: Well, I wasn't there exactly on that day. I got to town a couple of days latex—but I did see the parade celebrating the swallows' return. M: They have a parade? The people there must really like those swallows. W: Sure—they bring lots of tourists to town, and besides, the swallows eat insects, including mosquitoes. Where is the town of San Juan Capistrano?
