ones attitude consists of the drive, the commitment and the desire to achieve their goals. if one has strong beliefs about the goals that he can achieve and he displays good attitudes towards it, it would be no surprise to anyone that he will be able to achieve his goals.start believing in yourself that you can achieve your goals and with the right positive attitude, you will definitely be able to create the miracle (奇迹) that you have always dreamt of.语篇解读：坚定的信念和积极的态度对于一个人成功有巨大作用。1the author gives the example of michael phelps mainly to show _.apeople often succeed when they are wellknownbpeoples success comes from their strong beliefscnotable people have their own styles of livingdwe usually look up to the successful person解析：选b。细节理解题。根据文章第一段第二句可知
