　　      面对火                                             

　　有的心灵变成一缕缕青烟                                    

　　  细雨一洒就熄了                                         

　　有的心灵在烈火中熔冶                                      

熔冶出了钢铁的气魄                                       

答案

面对火

　　 有的心灵留下一股股焦臭

　　　　清风一吹就散了

　　　　　有的心灵在烈火中锻炼

　　　　锻炼出了黄金的性格

此题考查仿写句子的能力。所给示例为一段诗歌，仿写时除了句式要与原诗的各句保持一致外，更重要的是注意示例中各个诗句之间的关系，以及整段诗歌要表达的主题思想。示例诗段两个“有的心灵”之间构成对比关系，另外整段诗歌表达的是经受火的考验的不同心灵的表现，做题时要注意。
