补充资料:《淮中晚泊犊头》

淮中晚泊犊头

苏舜钦

春阴垂野草青青,时有幽花一树明。

晚泊孤舟古祠下,满川风雨看潮生。

这首小诗题为“晚泊犊头”,内容却从日间行船写起,后两句才是停滞不前船过夜的情景。

诗人叙述中所见的景象说:春云布满天空,灰蒙蒙地笼罩着淮河两岸的原野,原野上草色青青,与空中阴云上下相映。这样阴暗的天气、单调的景色,是会叫远行的旅人感到乏味。幸而,岸边不时有一树野花闪现出来,红的,黄的,白的,在眼前豁然一亮,那鲜明的影像便印在你的心田。

阴云,青草,照眼的野花,自然都是白天的景色,但说是船行所见,何以见得呢?这就是“时有幽花一树明”那个“时”字的作用了。时有,就是时时有,不时地有。野花不是飞鸟,不是走兽,怎么能够一会儿一树,一会儿又一树,不时地来到眼前供人欣赏呢?这不就是所谓“移步换形”的现象,表明诗人在乘船看花吗?

天阴得沉,黑得快,又起了风,眼看就会下雨,要赶到前方的码头是不可能的了,诗人决定将船告岸,在一座古庙下抛锚过夜。果然不出所料,这一夜风大雨也大,呼呼的风挟着潇潇的雨,飘酒在河面上,有声有势;河里的水眼见在船底迅猛上上涨,上游的春潮正龙吟虎啸,奔涌而来。诗人呢?诗人早已系舟登岸,稳坐在古庙之中了。这样安安闲闲,静观外面风雨春潮的水上夜景,岂不是很快意的吗?

我们欣赏这首绝句,需要注意抒情主人公和景物之间动静关系的变化。日间船行水上,人在动态之中,岸边的野草幽花是静止的;夜里船泊牧犊头,人是静止的了,风雨潮水却是动荡不息的。这种动中观静,静中观动的艺术构思,使诗人与外界景物始终保持相当的距离,从而显示了一种悠闲、从容、超然物外的心境和风度。
