问题补充：
单选题Inthepasttenyears,the________mountainclimber_________alotfromhisownadventurous_______A.experienced; experienced; experienceB.experience; experienced; experiencesC.experienced; has experienced; experiencesD.experience; has experience; experience
答案：
A解析考查experience用法和时态。。Experience作为经验，是不可数名词；作为经历，是可数名词。Experienced形容词：有经验的，经验丰富的；experience动词：体验，经历；in the past ten years常与现在完成时连用。句意：在过去的十年里，那位经验丰富的登山者已经从他自己的冒险经历中体验了很多。故A正确。
