Even if you walk exactly the same route each time - as with a sonnet - the events along the route cannot be imagined to be the same from day to day, as the poet's health, sight, his anticipations, moods, fears, thoughts cannot be the same.
即使你每次都走完全相同的路线——就像一首十四行诗一样——沿途发生的事情也不可能日复一日地一成不变，因为诗人的健康、视力、预期、情绪、恐惧和思想也不可能一成不变。
