工夫常负无心人

“工夫不负有心人”，几乎成了公认的真理。不知有多少文人做到“功到垂成”、“攻不十，不易器”。其实，对于古人这句话，只谈“工夫”，不谈“有心”，只谈了真理的一半，人世间，“工夫常负无心人”的事比“工夫不负有心人”的事，甚至还要多。  

“工夫”重要，“有心”、“无心”更重要。传说车和船都是黄帝发明的。我们的这位老祖宗，看见有一种叫“浮蓬”的草，秋后干枯以后，风一吹，在地上滚来滚去，于是发明了车；看见枯木在水面上漂，于是发明了船，而看到浮蓬滚来滚去，看到枯木漂到水上的，何止黄帝一人？为什么发明车船的“专利”属于黄帝？关键就是黄帝是个“有心”人，有人说，黄帝是人民群众的象征，发明车船的是人民群众，即便如此，人民群众有所发明，有所创造，也是那些有心的人。  

学过物理的人都知道，牛顿是发现“万有引力”定律的奠基人，牛顿小时候躺在苹果树下，看见苹果掉下来，于是提出疑问：“苹果为什么落到地上，不向天空飞去呢？”多么简单的问题，看到这种现象，并非牛顿始，为什么别人没有提出这样的问题，看来别人都没有像牛顿那样是个有心人。 

被人称为药圣的李时珍，怎么写出了《本草纲目》这部伟大著作？一因为他是个祖传医生，从父亲手里接过药箱，二因为他是有心人。他看到有个同行给一个癫狂病人开了一服药，其中有一味叫“防葵”，病人吃了很快就死了。另一个同行给身体虚弱的病人用了一味补药叫“黄精”，病人也死了，按古书记载，这些药本来都是不错的，李时珍经过研究，发现人们把防葵和狼毒，黄精和钩吻弄混了，而狼毒和钩吻都是极毒的药，于是决定修订药典。那两位用药致人死命的同行都没有想到这点。看来他俩都不像李时珍那样有心。  

“工夫常负无心人”，让我们记住这句话吧！这样或许可以减少一些劳民伤财的无效劳动，或许可以使我们的科学家、发明家成倍成倍地增加起来。每个人都应该问自己：是不是有心人？

It was two years ago today that the hunting ban came into force, supposedly ending centuries of tradition. However, the law has been an unmitigated failure—not that either side is shouting about it.
It was a nightmare vision that struck fear and loathing into the hearts of millions. When the hunting ban became law, it was said, 16,000 people would lose their jobs, thousands of hounds would be put down, rotting carcasses would litter the countryside, hedgerows would disappear, riders would face on-the-spot fines, law-abiding people from doctors to barristers would be dragged from their horses and carted off to prison, while dog owners would be prosecuted if their mutt caught a rabbit.
These were just some of the claims as desperate countryside campaigners battled to save their sport in the lead—up to the hunting ban, which Labour rammed into law using the Parliament Act on November 18, 2004.
For many, the fears were real. Others exaggerated as they fought an increasingly aggressive anti-hunting lobby which had rejected acres of independent evidence affirming that hunting is the most humane way of killing foxes. In the battle to "fight prejudice, fight the ban", every emotive argument was deployed.
For its part, the anti-hunting brigade extravagantly claimed that the ban would put an end to the rich parading in red jackets. A senior Labour MP, Peter Bradley, admitted in this newspaper that it was, as many suspected, about "class war". He lost his seat shortly afterwards. But people in red coats did not disappear.
In fact, none of the forecasts came true. What did happen was something nobody had predicted: the spectacular revival and growth of hunting with hounds. In short, the hunting ban has been a failure.
Today, on the second anniversary of the ban’s coming into force on February 18, 2005, new figures show that participation in the sport has never been higher. It is so cheerful that two new packs have been formed, something that has not happened for centuries.
They include the seductively named Private Pack, set up by the financier Roddy Fleming in Gloucestershire. It operates on an invitation—only basis, a sort of hunting private members’ club. This can only mean one thing: like it or not, hunting is cool. Young people are taking it up, enticed by the element of rebellion and the mystique of what actually happens as hunts attempt to keep within the law.

By saying "people in red coats did not disappear", the author implied that ______.

A．the upper class won the "war"

B．Bradley deserved his fate

C．the hunting ban did not work

D．the hunting ban was untimely
