听力原文： Our family is trying to decide where to go for a vacation this summer. Our son Tom wants to go to Yellow Stone Park again to see the bears. We did that last summer and what an experience it was! When we got there, we put up our tent and went to explore. As we returned, we heard our daughter Susie cry out and then we saw a bear enter our tent, Tom wanted his father to chase him away. His father said; "No, it's dangerous to chase a bear. And don't let him chase you." Susie said: "What shall we do？" "Maybe we ought to climb a tree." Tom said: "No, we've got to get him out of there. He might go to sleep in our tent." "Maybe we could make him leave if we put some honey outside for him to eat." Susie suggested. Then I said: "How are you going to get the honey？ It's in the tent," We watched the bear enter the tent and heard him upset everything inside. "It's foolish for us to try to catch hire." Said my husband. "Leave him alone and wait for him to come out." We waited but the bear stayed inside. We had to sleep in the car.
