An apprenticeship is a form of on-the-job training that combines workplace experience and classroom learning. It can last anywhere from one to six years, but four years is typical for most. An apprentice spends the majority of the time in a workplace environment learning the practical skills of a career from a journeyman--someone who has done the job for many years. The rest of the apprentice's time is spent in a classroom environment learning the theoretical skills the career requires. Being an apprentice is a full-time undertaking.

One of the advantages of apprenticeship is that it does not cost apprentices anything. The companies that hire them pay for school. What's more, it offers apprentices an "earn while you learn" opportunity. They usually start out at half the pay of a journeyman, and the pay increases gradually as they move further along in the job and studies. Near the end of the apprenticeship, their wages are usually 90 percent of what a journeyman would receive. Apprenticeship also pays off for employers. It can offer employers a pool of well-trained workers to draw from.

Despite the advantages, apprentices are usually required to work during the day and attend classes at night, which leaves little time for anything else. Sometimes, they might be laid off(下岗) if business for the employers is slow.

Once they have completed the apprenticeship and become journeymen, they receive a nationally recognized and portable certification and their pay also increases again. Some journeymen continue employment with the companies they apprenticed with; others go onto different companies or become self-employed contractors.

围棋的价值和地位是在与传统礼教观念斗争中确立起来的。围棋作为反映和体现人们心灵自由的智力博弈活动，在很长一段时间里，被认为不符合传统伦理观念。后来，人们逐步认识到这些观念都是不对的。从东汉中后期到魏晋时期，人们开始从生命意义上认识围棋的价值，就把围棋作为自觉的艺术追求和精神宣寄的工具，并把它纳入儒士必备的艺技。围棋的价值和地位是从正反两方面的社会实践对比中确立起来的。人们在围棋活动的实践中逐渐认识到，围棋本身具有娱乐、教育、竞技、交际等功能。弈棋活动的负面作用不能归咎于围棋本身，而是人们自己对“度”的把握不好造成的。
根据这段文字，下列对围棋的认识不正确的一项是______。

A．围棋是能够反映和体现人们心灵自由的一项智力博弈活动，曾经长期被认为不符合传统伦理观念
B．当人们从生命意义上认识到围棋的价值，把它作为自觉的艺术追求后，围棋就成为儒士必备的艺技
C．围棋的价值和地位是在与传统礼教观念的斗争中，在正反两方面的社会实践的对比中确立起来的
D．围棋活动产生的一些负面作用是因为人们自己没把握好“度”造成的，不能归咎于围棋本身
