14（）
A.drill
B.implement
C.exercise
D.apply
参考答案：C
解析：
exercise在题句中用作动词，意思是“施行，运用”，exercise life即“在生活中实行……”，根据句意“要造就一代对生活抱有乐观态度的人，第一步是自己要看到生活中光明的一面”应该选exercise。又如：exercise power/self-control/influence over others“行使权力(运用闩制力对他人产生影响)”。[A]perceive意为“察觉到，注意到，认为”，perceive life意思是“发觉有生命存在”，显然在句中不合乎逻辑；[B]implement“实施，执行”，如：implement policy/protocol“实施一项政策(实现协议)”；[D]apply“应用，运用”，如：apply theory to practice“把理论运用到实际中去”，apply不能接life作宾语，但可以说apply…to life“把……运用到生活中去”。
