天空飞的是什么？是飞机，不是，那是什么？                                                                                                                                                                那是一滴泪。                                                                                                                                                                                                自从忧伤在心里飘荡的那一刻起，泪就想飞翔 。                                                                                                                                                   为什么要飞翔？                                                                                                                                                                                唯有飞翔才能获得更多的自由，才能散去无尽的忧伤。
