听力原文：M: Are you looking forward to your trip to Canada? W: I can't wait to see Canada, but I'm scared stiff of the journey. My husband insists on flying, but I want to sail. Planes make me nervous. M: There's nothing to be frightened of. How many planes fly across the Atlantic every day? W: I've no idea. Hundreds, I suppose. M: And how often do you hear of a crash? ... Once or twice a year? W: Yes, but planes fly so high and fast that once is enough. M: Look, there are more road casualties per day than air deaths per year. Air transport is really safe compared with road transport. W: I'd still prefer to go by sea. Ships may not travel fast but at least you can relax I'd love a trip on a luxury liner like the Queen Elizabeth Ⅱ. M: It's fine if you are a good sailor, but have you ever traveled far in a rough sea? W: No, I've only bean in a boat once. I sailed down the River Thames on a sightseeing tour But in any case I'd rather be sea-sick than dead. (20)
