67.阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。Last summer, we moved into a beautiful house where sunlight flooded the kitchen every morning. The only downside was the backyard: behind tall, messy bushes lay an old pond, dry and smelly."Let's bring it back to life!"I suggested. My parents smiled and agreed.It became our family's summer project. We cleaned out the mud and lined the edge with pretty stones. At the garden shop, I chose cattails and water lilies. "They float like little umbrellas,"Mum said."Yes,"I replied proudly, and they keep the water cool and clean."Then came the best part: two tiny goldfish — Spotty and Sparkly.I also asked about a pond heater. I'd read that if the pond froze solid in winter, the fish would run out of oxygen. They needed a small hole in the ice to breathe, which a heater could keep open. But they were sold out. As we left, I noticed a poster listing clever ideas to prevent ice from sealing (封住) the pond — for example, keeping the water moving, since flowing water doesn't freeze easily. I thought we'd get a heater long before winter, so I didn't think much of them.Soon, baby fish appeared! Frogs and butterflies often visited too. Our pond felt like a living ecosystem.Then one evening, the weather report warned of an early freeze — colder and sooner than usual. My stomach dropped. We still didn't have a heater! Dad immediately ordered one online. "It'll arrive before the ice forms,"he promised.Early the next morning, I woke to a world covered in white. I threw on my coat and ran to the pond. It was frozen with clear ice — no open water! Yet I could still see the fish moving slowly beneath.I rushed back inside. Dad had already called the delivery company, but they said it wouldn't arrive today because of the icy roads. "The fish can only last half a day without fresh air!"I cried."Let's think of something new,"Mum said.注意：(1)续写词数应为150左右；(2)请按如下格式在答题卡的相应位置作答。
