The world is eager to seek prodigies today because talented personality and instinct gifts seemto be viewed to more and more precious and difficult to find today, consequently I agree with the claim that children with special talents should be protected from being oblivious and effected by some other detrimental things from outside before they have the opportunity to perform the talents. But I am not in favor with the proposal that these children should be provided training at an early age to develop their talents.
The chief reason for both the society and their parents to protect such children is that some gifted children in several specific areas, like art and mathematicas, are too valuable and if discovered early and cultivated well, they may initiate an new echo of their field or solve some most difficult problems. Take Mozart as an example, being found with a high talents with music, he started playing music at an age of three, and performed throughout the country in the later years, which tempered his skills remarkably. As a result, he became a milestone of the history of the music. Another illustration is Chinese S player Ding Junhun, who is training for the game from a very early age, about only 10years old,  and now, he is regarded as the first one to introduce and advertise the game in China.
Paying early attention to those children possesses another advantage that all these external attention may act as a catalyst and precipetate their growth as a master, or can scrutinize them from giving  up. The most beneficial function for those who have no economical ability to pursue their gifts is that the attention from the whole societ may solve them such problems. Take the famous popular singer Song Zuying,as an example, she grew up in a remote and impoverished village in Hunan province, her talented singing skills are found to be remarkable but she could not afford to get access to further training, them the mass medium all reported her story, and the music college patron her musical study since she was only about 10 or 11years old. Now she has been one of the most popular singers in China.
On the other hand, early training can also impede some children's regular growth, for it is hard to distinguish from the normal children and those genious. If the children are not interested in the training the parents give to them because they are really not good at the skills, the result can be advers. What happens in China nowadays can be a compelling illustration. Most Chinese parents desire their children to be a music prodigy or a great painter when they grow up, and even have scripted their children's future. Correspondingly, they urged them to accept training on those subjects day after day without weekend and holidays, 3 or 4 hours per day. But how many of them possess the gifts to be a master? As a resul most children are reluctant to approach anything relating the subjects in the rest of their life.
What also makes early training not proper is that they may overstate the talents and make commercial use with the talents, which may damage and even kill the children's talents. Take the "Olympic girl" as an example, Lin Miaoke, who is only 8 years old when she was chosen to be the lucky girl to sing in the opening ceremony in 2008 Olympic Games. After the ceremony, she was paid so much attention and participated in many commercials, performance and even movies, subsequently, her school life ended and then the overuing of her skills brought her detrimental influence, and now she is almost out of people's eyesight.
In summary, I fundamentaly agree that those talented children should be protected but oppose that they should be given such early training for the negative effects that may have in their later life.
