while Dad slept:“You stand outside the door and play lookout(放哨)while I go, and I'll stand outside the door and play lookout while you go.” I had terrible pictures in my mind:“Honey, where are the kids?” “What?! Oh, Gosh...I thought they were being awfully quiet.” We were never actually left behind in a strange city, but we weren't about to take any chances. On the fourth or fifth night, we had trouble finding a hotel with a vacancy. After driving in vain for some time, Mom suddenly got a great idea:Why didn't we find a house with a likely-looking backyard and ask if we could set up tent there? David and I became nervous. To our great relief, Dad turned down the idea. Mom never could understand our objections(反对). If a strange family showed up on her front doorstep, Mom would have been delighted. She thinks everyone in the world is as nice as she is. We finally found a vacancy in the next town. 注意: 1.所续写短文的词数应为150左右; 2.至少使用5个短文中标有下划线的关键词语; 3.续写部分分为两段,每段的开头语已为你写好; 4.续写完成后,请用下划线标出你所使用的关键词语。
