听力原文：W: Just a few reminders are necessary before you climb in. First, make sure you are properly grounded at the shore. M: What do you mean by that? W: I mean your canoe should be secure enough so that the moment you get in it, it doesn't float away on you. M: But you wouldn't want it to be too grounded, would you? Otherwise, it's a lot of work to push it from the shore. W: Right, so try to have it parked securely enough that a simple shove from your paddle is all it takes to get you offshore. M: What if the currents keep pushing you back to shore, after you've pushed off? W: In that case, you may wish to 'go with the flow' and let it glide you along the edges until you come across an area where you can push towards the center. M: OK, got it. So, can we get in and get going? I am dying to try out an Eskimo roll. W: All right, but there are still some other tips I have to remind you of. For example, do you remember what you should never do when you're pushing off? M: Yeah, I remember. Never lean forward. Always lean away from the shore. Let's just get out there so I can practice my Eskimo roll. W: Come on Stan, as they say--walk before you run. M: See you on the other side of the shore. W: OK. Good luck! M: Thank you again! (1)
