[解析]
(1)C,细节理解题.由第三段中的"He expects us to be excellent not just on the court but in the classroom"和最后一段中的"unlike the coaches of my youth,this man was interested in how he did off the court.He always made sure I kept up with my studies and was able to be trusted.I can honestly say that on other coach has given me so much advice on how to succeed in basketball,but more importantly,in life"可知,Brian和其他教练的区别在于:其他教练只关注队员们在篮球方面的表现,而Brian还希望他的队员们在学习上也要表现的好.故C选项切题.
(2)D.词义猜测题.由"not putting forth my full potential"可知,作者没有将自己的全部潜力发挥出来,由此可以推知,作者没有倾尽全力,付出的努力不够.故D选项正确.
(3)A.推理判断题.由第三段中的"He didn't expect 100% effort,he expected 200% effort"可知,教练对队员们要求非常严格.由最后一段中的"He always made sure I kept up with my studies and was able to be trusted.I can honestly say that on other coach has given me so much advice on how to succeed in basketball,but more importantly,in life"可知,教练在队员的个人成长方面给队员很大的影响和帮助.故A选项切题.
