月光下的探访

李汉荣

  ①今夜风清露白,月明星稀,宇宙澄澈,月光下的南山显得格外端庄妩媚。斜坡上若有白瀑流泻,那是月辉在茂密的青苹上汇聚、摇曳,安静,又似乎有声有色,斜斜着涌动不已,其实却一动未动,这是层出不穷的天上雪啊!

  ②我爬上斜坡,来到南山顶,是一片平地,青草、野花、荆棘、石头都被整理成一派柔和,蝈蝈弹奏着我熟悉的那种单弦吉他,弹了几万年了吧。这时候曲调好像特别孤羊忧伤,一定是怀念着它新婚远别的情郎。我还听见不知名的虫于在唧唧夜话,说的是生存的焦虑,饥饿的体验,死亡的恐惧,还是月光下的快乐旅行?在人之外,还有多少生命在爱着、挣扎着、劳作着、歌唱着,在用它们自己的方式撰写着种族的史记。我真想向它们问候,看看它们的衣食住行:既然有了这相遇的缘分,我应该对它们提供一点力所能及的帮助,它们那么小,那么脆弱,在这庞大不可测的宇宙里生存是怎样的冒险,是多么不容易啊。然而,常识提醒我,我的探访很可能令它们恐惧.,最大的帮助就是不打扰它们。慈祥的土地和温良的月光会关照这些与世无争的孩子的,这么一想我心里的牵挂和怜悯就释然了。

  ③我继续前行。我看见几只蝴蝶仍在月光里夜航,这小小的宇宙飞船,也在无限地做着短促的飞行,在力所能及的范围内探索存在的底细,花的底细。此刻它们是在研究月光与露水相遇,能否勾兑出宇宙中最可口的绿色饮料?

  ④我来到山顶西侧的边缘,一片树林寂静地守着月色。偶尔传来一声鸟的啼叫,好像只叫了半声,也许忽然想起了作息纪律,怕影响大家的睡眠,就把另外半声叹息咽了回去——我惊叹这小小生灵的伟大自律精神.但我想它的灵魂里一定深藏着我们不能如晓的智慧.想想吧,它们在天空上见过多大的世面啊.它们俯瞰过,超越过多么多么多的事物,它们肯定从大自然的灵魂里获得了某种神秘的灵性。我走进林子,看见一棵橡树上挂着一个鸟巢。我踞起脚尖,发现这是一个空巢,几根树枝一些树叶就是全部的建筑材料,它该是这个世界最简单的居所了,然而就是它庇护了注定要飞上天空的羽毛;那云端里倾洒的歌声,也是在这里反复排练。而此时它空着,空着的鸟巢盛满宁静的夜光,这使它看上去吴像是-个微型的天堂。

  ⑤如果人真有来生,我期望我来生只是一只太阳雀鸟或知更鸟,几粒草籽、几滴露水就是一顿好午餐。然后我用大量时间飞翔和歌唱。我的内脏与灵魂都朴素干净,飞上天空,不弄脏一片云彩,掠过大地,不伤害一片草叶。飞罩了,天黑了,我就回到我树上的窝——我简单的卧室兼书房一一因为在夜深的时候,我也要读书,读这神秘的寂静和仁慈的月光。

Disease, poverty, hate, love-Charles Dickens' stories opened his readers' eyes to the most important themes of his age.Two hundred years on, his stories still speak volumes across the world, proving that Dickens' legacy (遗产) was far greater than just "great literature".

February 7 marks the 200th anniversary of the writer's birthday.To mark this date, BBC writer Alex Hudson listed six things Dickens gave the modern world.Let's take a look at two of them.

A while Christmas

Dickens is described as "the man who invented Christmas" -not the religious festival, but the cultural aspects that we associate with the festive (喜庆的) season today.

In the early 19th century, Christmas was barely worth mentioning, according to critic and writer Leigh Hunt.The committee which ran the Conservative Party even held ordinary business meetings on Christmas Day - unthinkable in the West nowadays, when everyone, but the most necessary workers takes at least three days off.

Many people believe that Dickens' popular depictions(描绘) of the festive period became a blueprint for generations to come.In his classic novel, A Christmas Carol, he not only put forward the idea of snow at Christmas,but also painted a picture of glowing warmth-“home enjoyments, affections and hopes".

In his biography of Dickens, Peter Ackroyd wrote, "Dickens can be said to have almost single-handedly created the modern idea of Christmas."

"Dickensian" poverty

Dickens was one of the first to take an honest look at the underclass and the poor of Victorian (the period during British Queen Victoria's reign from 1837 to 1901) London.

He helped popularize the term "red tape" to describe situations where people in power use needless amounts of bureaucracy (官僚作风) in a way that particularly hurts the weaker and poorer members of society.

"Dickensian" has now become a powerful word for describing an unacceptable level of poverty.In 2009, when the president of the Association of Teachers and Lecturers in the UK wanted to talk about deprivation in some areas, of Britain, she did not use words like "terrible" or "horrific", but rather described it as "life mirroring the times of Dickens".
