夜.有感

                                                                        冬夜有感——记研究生程序员的学习生涯

                                                                                          一树一影一婆娑，
                                                                                          一年一岁又蹉跎。
                                                                                           莫道春来尚时早，
                                                                                           愿作桑蚕化羽蝶。
