Chinese are very generous when it comes to educating their children. Not caring about the  money, parents often send their children to the best schools or even abroad to England, the United States and Australia. They also want their children to take extra-course activities where they will either learn a musical instrument(乐器) or ballet, or other classes which will give them a head in life. The Chinese believe that the more expensive an education is, the better it is. So parents will spend an unreasonable amount of money on education. Even poor couples will buy a computer for their son or daughter. However, what most parents fail to see is that the best early education they can give their children is usually very cheap.

Parents can see that their children are very skilled in some areas while poor in others. What most parents fail to realize though, is that today's children are short of self-respect and self-confidence.

The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills that they need to be confident, happy and clever.

Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework. Teaching a child to cook will improve many of the skills that he will need later in life. Cooking requires patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and finish his job successfully step by step. His result, a well-cooked dinner, will give him much satisfaction and lots of self-confidence.

Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse(激发) his interest. He will spend hours looking at them, trying to fix them; your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.

月 光

①翻开唐诗宋词，翻开元曲，几乎满篇月光，中国古代文人，鲜有不写月光的。月光历世照着我们，总是那样如期的圆，如期的缺，那样的清辉，那样的如水。

②只是近些年来，我见得它少了，模糊了。它缓缓隐退于我的生活，数月，经年，没有看到它在窗前升起。它曾是那样皓皓满天，现在它怎么了，我已很难见到它。然而，我知道它仍在，仍存在于天空，存在于我内心的某一角落，却已是锈迹斑斑。

③是夜，我好像听到了它在微弱地喊我，我的身体感觉到了它，我的心感觉到了它，它用无声的嗓音喊我，用盈盈泪光喊我，用不存在的小手触摸我。我缓步登上楼阁晾台，向天空望去，可它在哪呀？前面一栋黑糊糊的大楼，遮住了半个天空，我看不到它。

④我脱下便衣，换上西装，蹬上皮鞋，妻问我何去，我无法对她说。下得楼来，直奔市区的紫荆山公园，因那里地势相对开阔，建筑物又少，接近自然。我穿过车流如水的金水大道，那些没有烧透的汽油味与尘土味，混合在一起，在空气中飘浮迷漫。霓虹灯在辨认着各色人脸，彩色探照灯，把商业大楼照得通体辉煌。在一人造小山上，我看到了它，它在东边群楼的缝隙中，左冲右突，艰难地上升。它怎么了？竟有些黯淡，也小了许多，全然不像旧时月。我看到它的脸，有不易察觉的愁容和倦意，它病了吗？那么无力、微弱、无奈，像老人被无边喑哑所围绕。它淡淡地照着我，照着我身边的假山，沉睡的石头，无语的松柏，用它的残缺唤醒着我体内的残缺。多年了，月光渐去渐远，我一直生活在没有月光的生活中，那无边的琐碎、烦恼、不安，遮蔽了它。谁能说没有月光的生活不是一种残缺。

⑤我童年的月光，可不是这个样子。

⑥彼时，月光是明亮、洁净的，一尘不染，尚带有原野上植物那丝丝的甜味。在南阳盆地腹地，一个小村庄中，木格子窗内，煤油灯结着浅浅灯花，我和李白、杜甫、陆游等我所敬仰的诗人先贤，频频相会在一本本发黄的书里。他们的诗句让我迷醉、颤抖。每每抬头，向窗外望去，满院皆是月光，那月光像水，似银，从高空流淌下来，在地上铺厚厚的一层，把方方正正的小院子撑满。枣树叶子一明一暗，像无数闪动着的小眼睛。蛐蛐在墙角处鸣叫，青蛙在村边此起彼伏。它们在疯长着，使这些月光更亮，更有力。村西就是终年流淌着的涧河，水草浮动，鱼虾成群，清澈见底。此时正无声地把大片大片的月光，运向不知道的远方。我的母亲和邻居家的三婶，坐在院中纳鞋底，她们很长时间不说一句话，月光带着高天的凉意和香气，游走在她们中间，她们便成了月光的雕像。此时，月光已融入了我的身体，融入了我的生命，它照在土地上，因此也就变成土地；它照在村舍上，因此也就成了村舍。后来，无论我到何处，在有月亮的晚上，我总要留意向天上看去，月亮就成了我的一个情结。只是我很纳闷，为何再也看不到故乡那样明亮、干净的月光了。我所看到的月光，总像是掺了某种不洁的杂质，某种病态。这是为什么呢，莫非若古人所说：月是故乡明。有一次回乡，我故意选择了有月光的日子，目的是看月，寻找往昔失去的月光。奇怪的是，故乡的月光也同样含有杂质和病态。一次，我把这种对于月亮的感觉说给一位朋友听，他说他也有同样的感觉，说罢，二人相对无言，心中都有着深深的失落。

⑦一个人，要深入月光，首先要成为月光，才能感受月光，月光需要人的配合与栽种，才能够长出更为繁茂的月光。只是现代人已没有这种心境，无法深入到月光的内部。

⑧何处才能找到我幼时的月光？
