我来了

严辰

                                                                                                      我来了，

                                                                                                      像一只大雁，

                                                                                                      带着热情的歌唱，

                                                                                                      从荒凉无边的沙漠，

                                                                                                      穿过万里长空，

                                                                                                      来到伙伴们生动活跃的队伍里。

                                                                                                      我来了，

                                                                                                     像山谷里流出的

                                                                                                      一支清冷的泉水，

                                                                                                      跳过岩石，冲过堤坝，

                                                                                                      经过小河，经过大江，

                                                                                                     奔流到广阔的

                                                                                                     波涛汹涌的海洋。

                                                                                                     我来了，

                                                                                                     像一个飘泊的流浪人，

                                                                                                     跨过饥寒的道路，

                                                                                                     跨过被迫害的道路，

                                                                                                     跨过侮辱和残暴

                                                                                                     所铺成的艰险的道路，

                                                                                                     含着一把辛酸泪投进了慈母的怀抱……

                                                                                                     我来了，

                                                                                                     带着长久的相思，

                                                                                                     长久的爱慕。

                                                                                                     我来了，

                                                                                                     带着默默的骄傲，

                                                                                                     和发自心底的

                                                                                                     不可遏止的欢笑……

                                                                                                     我来了！
