每一缕阳光都该照耀到新生命

张鸿勋

  ①那天早上发生了日食,我看到了现场直播,也看到了媒体铺天盖地的报道和宣传。五百年一遇,很多人都说太幸运了,太震撼了,有的甚至说,太值了。尤其是重见天日的那一刻,感觉看到了极大的奇迹。 

  ②我问朋友:日食是什么?很多种答案,有一位朋友回答:是影子,是月亮的影子。我再问:一个影子,人们为什么会那么欣喜若狂呢?答:是感觉到一种重见天日的欣喜。

  ③人们通常认为一些很不寻常的事情才是奇迹,其实每时每刻都有和日食一样的所谓的奇迹发生,而每一缕新阳光照耀到的都应该是新的生命,因为那是新的当下。

       ④说到阳光,我想起了第一次下矿井,那是印象非常深刻的经历,在极为寂静的井下500米处,头上的矿灯照射出隐约灯光,周围异常安静,只有近处岩层渗出的地下水发出的“叮咚,叮咚”的声音,掺杂着远处隐约传来的掘煤的爆破声。

       ⑤那个矿井和后来我去过的其他矿井不同,煤层质量虽然很好,但是非常薄,是斜带型分布,最窄的地方只有70厘米高,上下都是岩层,进去之后必须趴下来手脚并用地爬行。我们爬进了矿工俗称的“掌子面”,也就是工作区。一线矿工在这里把小型爆炸后崩落的煤块向外搬运。我第一次体验了矿工是怎样工作的,也趴在地上比划了两下,发现这是一种常人难以想象的工作方式和工作环境,他们像是地层深处的蚯蚓。

       ⑥我们实在待不下去的时候,准备上来,钻入上下有铁板、周围一圈铁栅栏的吊笼,这就是电梯了,除了没有楼层显示以外,电梯速度很均匀,嘎吱作响,500米,相当于一百多层楼宇的封闭电梯,手抓着吊笼上冰冷的螺纹钢,所有人都鸦雀无声。当吊笼从地面升起的刹那,刺眼的阳光洒在我们每一张黧黑的脸上,我们全眯起眼睛,眼泪流下来。走出吊笼,我在台阶上静默良久。现在想来,那个时候的感动,应该和看到日食没有什么不同,再重复一次:每一缕阳光都应该照耀到新的生命,因为那是新的当下。

        ⑦如果我们还有解不开的烦恼,去体验吧:如果你觉得自己郁闷得要自杀,带点好吃的去一次儿童医院的白血病病房;如果你觉得自己病得比较重,带点玩具去看看脑瘫的孩子;如果你痛失了亲人,去看看地震灾区人们的生活;如果你觉得学业或者工作不堪重负,下一次矿井吧。说多少劝解的话都没有意义,真的,请体验一次:请暂时把你认为不可解决的烦恼扔开,去一趟,我保证你会把烦恼彻底抛开,拍拍灰尘嘲笑自己。

       ⑧因为,这是我曾经的体验。(摘自2010年《青年文摘》,有改动)

A

It is natural that young people are often uncomfortable when they are with their parents. They say that their parents don't understand them. They often think that their parents are out of touch with modem ways; that they are too serious and too strict with their children; and that they seldom give their children a free hand.

It is true that parents often find it difficult to win their children's trust and they tend to forget how they themselves felt when young.

For example, young people like to act on the spot without much thinking. It is one of their ways to show that they have grown up and they can face any difficult situation. Older people worry more easily. Most of them plan things ahead, at least in the back of their minds, and do not like their plans to be upset by something unexpected.

When you want your parents to let you do something, you will have better success, if you ask before you really start doing it.

Young people often make their parents angry with their choices in clothes, in entertainment and in music. But they do not mean to cause any trouble—— it is just that they feel cut off from the older people's world, into which they have not yet been accepted. That's why young people want to make a new culture of their own. And if their parents do not like their music or entertainment or clothes or their ways of speech, this will make the young people extremely happy.

Sometimes you are so proud of yourself that you do not want your parents to say "yes" to what you do. All you want is to be left alone and do what you like. It is natural enough, after being a child for so many years, when you were completely under your parents' control.

If you plan to control your life, you'd better win your parents over and try to get them to understand you. If your parents see that you have a high sense of responsibility, they will certainly give you the right to do what you want to do.
