听力原文：M: When did you last go to the seaside? W: Last July. We spent all our days on the beach. M: Did you have a good time there? W: Yes. We swam and dived off the rocks into the sea. We also played game on the sand. M: The summer vacation is coming. Will yon go there this year? W: Fm afraid I won't. My father will go to Guangzhou on business next week. He won't back until September. M: What a pity! How long can you hold your breath under the water? W: I don't know. Perhaps more than one minute. M: That's wonderful. Let us go swimming tomorrow in the river. Is that right? When did the woman go to the seaside for the last time?
