关于丁尼生的诗 《break break break》的几个问题1.Why does the poet describe the stones as "cold"and "gray"?2.What effect do the joyful scenes in the second stanza bring to the whole poem?3.Whose is the "voice that is still"?以下是全文"Break,Break,Break"Break,break,break,On thy cold gray stones,O Sea!And I would that my tongue could utterThe thoughts that arise in me.O well for the fisherman's boy,That he shouts with his sister at play!O well for the sailor lad,That he sings in his boat on the bay!And the stately ships go onTo their haven under the hill:But O for the touch of a vanish'd hand,And the sound of a voice that is still!Break,break,break,At the foot of thy crags,O Sea!But the tender grace of a day that is deadWill never come back to me.
