                                                                                                         《诗经•关雎》
                                                                                关关雎鸠，在河之洲。窈窕淑女，君子好逑。
                                                                                参差荇菜，左右流之。窈窕淑女，寤寐求之。
                                                                                求之不得，寤寐思服。悠哉悠哉，辗转反侧。
                                                                                参差荇菜，左右采之。窈窕淑女，琴瑟友之。
                                                                                参差荇菜，左右芼之。窈窕淑女，钟鼓乐之。
                                                                                                             《诗经•蒹葭》
                                                                                蒹葭苍苍，白露为霜。所谓伊人，在水一方。
                                                                                溯洄从之，道阻且长。溯游从之，宛在水中央。
                                                                                蒹葭萋萋，白露未晞。所谓伊人，在水之湄。
                                                                                溯洄从之，道阻且跻。溯游从之，宛在水中坻。
                                                                                蒹葭采采，白露未已。所谓伊人，在水之涘。
                                                                                溯洄从之，道阻且右。溯游从之，宛在水中沚。
