With that, the old cob set his wings for a dive(俯冲). Aiming directly at the big window, with his neck held straight, he was ready for the crash. He drove quickly and hit the window at full speed. The glass broke with a sudden, loud noise, setting off the alarm bell as well. The whole music store shook, and musical instruments fell onto the floor. The salesgirl screamed in panic, not knowing what was going on. (65 words)
The cob felt a serious pain. It was a piece of broken glass that cut into his left wing. But he was in such a hurry that not a single second could be spared for the wound. He grasped the trumpet, turned sharply in the air, flew out through the hole in the window and over the roofs of Billings city. “Stop! Thief!” As he flew higher, he heard people shouting below.

【解析】
【分析】
本篇书面表达是读后续写。通过阅读所给文章可知，本文讲述了一只雄天鹅向Billings市飞去，去寻找一个小号；它脑子里充满了各种各样的烦恼，以前从来没有去找过小号，它也没有钱。黄昏时分，它到达了目的地，经过一番寻找，它发现了一个小号，它勇敢地向小号冲了过去。
【详解】续写部分分为两段，第一段开头是：说完，老雄天鹅张开翅膀准备俯冲，所以本段应该写老天鹅向有小号的商店俯冲过去，速度很快，撞到了商店的玻璃上，商店的警报响了，女售货员不知所措。第二段开头是：雄天鹅感到一阵剧痛。本段应该写雄天鹅为何疼痛，它顾不上疼痛，抓住小号朝天空飞去，有人喊抓小偷，雄天鹅顾不上这些了，它眼睛里闪烁着幸福的光芒。因为它最后成功了!
续写时要求使用5个以上短文中标有下划线的关键词语增加了写作难度，我们要熟悉所给划线词语，恰当的时候加以运用。最后还要注意所续写短文的词数应为150左右；续写完成后，请用下划线标出你所使用的关键词语。按要求完成写作任务。
