阅读《咬文嚼字》选段，回答问题。

　　有些人根本不了解文字和情感的密切关系，以为更改一两个字不过是要文字顺畅些或是漂亮些。其实更动了文字，就同时更动了思想情感，内容和形式是相随而变的。姑举一个人人皆知的实例。韩愈在月夜里听见贾岛吟诗，有“鸟宿池边树，僧推月下门”两句，劝他把“推”字改成“敲”字。这段文字因缘古今传为美谈，今人要把咬文嚼字的意思说得好听一点，都说“推敲”。古今人也都赞赏“敲”字比“推”字下得好，其实这不仅是文字上的分别，同时也是意境上的分别。“推”固然显得鲁莽一点，但是它表示孤僧步月归寺，门原来是他自己掩的，于今他“推”。他须自掩自推，足见寺里只有他孤零零的一个和尚。在这冷寂的场合，他有兴致出来步月，兴尽而返，独往独来，自在无碍，他也自有一副胸襟气度。“敲”就显得他拘礼些，也就显得寺里有人应门。他仿佛是乘月夜访友，他自己不甘寂寞，那寺里假如不是热闹场合，至少也有一些温暖的人情。比较起来，“敲”的空气没有“推”的那么冷寂。就上句“鸟宿池边树”看来，“推”似乎比“敲”要调和些。“推”可以无声，“敲”就不免剥啄有声。惊起了宿鸟，打破了岑寂，也似乎平添了搅扰。所以我很怀疑韩愈的修改是否真如古今所称赏的那么妥当。究竟哪一种意境是贾岛当时在心里玩索而要表现的，只有他自己知道。如果他想到“推”而下“敲”字，或是想到“敲”而下“推”字，我认为那是不可能的事。所以问题不在“推”字和“敲”字哪一个比较恰当，而在哪一种境界是他当时所要说的而且与全诗调和的。在文字上“推敲”，骨子里实在是在思想情感上“推敲”。

Parents whose children show a special interest in a particular sport feel it very difficult to make a decision about their children’s careers. Should they allow their children to train to become top sports men and women? For many children it means starting school work very young, and going out with friends and other interests have to take a second place. It’s very difficult to explain to a young child why he or she has to train five hours a day, even at the weekend, when most of his or her friends are playing.

Another problem is of course money. In many countries money for training is available from government for the very best young sportsmen and women. If this help can not be given, it means that it is the parents who have to find the time and the money to support their child’s development—and sports clothes, transport to competitions, special equipment, etc. can all be very expensive.  

Many parents are worried that it is dangerous to start serious training in a sport at an early age. Some doctors agree that young muscles may be damaged by training before they are properly developed. Professional trainers, however, believe that it is only by training young that you can reach the top as a successful sports person. It is clear that very few people do reach the top, and both parents and children should be prepared for failure even after many years of training.
