紫藤萝瀑布(节选)

    ①从未见过开得这样盛的藤萝,只见一片辉煌的淡紫色,像一条瀑布,从空中垂下,不见其发端,也不见其终极。只是深深浅浅的紫,仿佛在流动,在欢笑,在不停地生长。紫色的大条幅上,泛着点点银光,就像迸溅的水花。仔细看时,才知那是每一朵紫花中的最浅淡的部分,在和阳光互相挑逗。

    ②这里春红已谢,没有赏花的人群,也没有蜂围蝶阵。有的就是这一树闪光的、盛开的藤萝。花朵儿一串挨着一串,一朵接着一朵,彼此推着挤着,好不活泼热闹!

    ③“我在开花!”它们在笑。

    ④“我在开花!”它们嚷嚷。

    ⑤每一穗花都是上面的盛开、下面的待放。颜色便上浅下深,好像那紫色沉淀下来了,沉淀在最嫩最小的花苞里。每一朵盛开的花像一个张满了的小小的帆,帆下带着尖底的舱,船舱鼓鼓的;又像一个忍俊不禁的笑容,就要绽开似的。那里装的是什么仙露琼浆?我凑上去,想摘一朵。

    ⑥但是我没有摘。我没有摘花的习惯。我只是伫立凝望,觉得这一条紫藤萝瀑布不只在我眼前,也在我心上缓缓流过。流着流着,它带走了这些时一直压在我心上的焦虑和悲痛,那时关于生死谜、手足情的。我浸在这繁密的花朵的光辉中,别的一切暂时都不存在,有的只是精神的宁静和生的喜悦。

    ⑦这里除了光彩,还有淡淡的芳香,香气似乎也是浅紫色的,梦幻一般轻轻地笼罩着我。忽然记起十多年前家门外也曾有过一大株紫藤萝,它依傍一株枯槐爬得很高,但花朵从来都稀落,东一穗西一串令仃地挂在树梢,好像在察颜观色,试探什么。后来索性连那稀零的花串也没有了。园中别的紫藤花架也都拆掉,改种了果树。那时的说法是,花和生活腐化有什么必然关系。我曾遗憾地想:这里再看不见藤萝花了。

    ⑧过了之么多年,藤萝又开花了,而且开得这样盛,这样密,紫色的瀑布遮住了粗壮的盘虬卧龙般的枝干,不断地流着,流着,流向人的心底。

    ⑨花和人都会遇到各种各样的不幸,但是生命的长河是无止境的。我抚摸了一下那小小的紫色的花舱,那里满装生命的酒酿,它张满了帆,在这闪光的花的河流上航行。它是万花中的一朵,也正是由每一个一朵,组成了万花灿烂的流动的瀑布。

    ⑩在这浅紫的光辉和浅紫色的芳香中,我不觉加快了脚步。

    Three years ago, when I entered my school for the first time, I was welcomed by students wearing white shirts with a badge (徽章) saying “Prefect” on them, who greeted me with the1“Welcome to Huaxia Middle School”.
