阅读下面的诗歌,完成下面问题。

**偶成**戴望舒

如果生命的春天重到,古旧的凝冰都哗哗地解冻,那时我会再看见灿烂的微笑,再听见明朗的呼唤——这些迢遥的梦。这些好东西都决不会消失,

因为一切好东西都永远存在,它们只是像冰一样凝结,而有一天会像花一样重开。 

1945年5月31日下列对这首诗的赏析,不恰当的一项是()

A.诗歌通过抒写“如果生命的春天重到”的“梦”,表达了诗人对光明未来的深情呼唤和对抗战胜利的坚定信念。B.第二句中“古旧的凝冰”喻指中华民族因历史悠久和专制暴政而被凝结、窒息的生命力。C.诗歌第一节写想象中的美好情境,第二节再给出其中道理,这种结构使传达的信念更富说服力和感染力。D.诗歌多次出现“重到”、“再看见”、“再听见”、“重开”等字眼,隐含有生命循环的悲观意味。
