阅读古诗《观沧海》，完成小题。
                                                                                                观沧海
                                                                                                  曹操
                                                                                       东临碣石，以观沧海。

                                                                                       水何澹澹，山岛竦峙。

                                                                                       树木丛生，百草丰茂。

                                                                                       秋风萧瑟，洪波涌起。

                                                                                       日月之行，若出其中；

                                                                                       星汉灿烂，若出其里。

                                                                                       幸甚至哉，歌以咏志。
