答案：
A. Mo Yan’s years of effort was well deserved
B. his folks back at home were on top of the world.
C. the current network evaluation is full of envy and jealousy
(答案→)D. Mo Yan felt that his years of effort paid off
解析：考查句子结构：逗号前面是现在分词的完成式，说明句子的主语和分词的逻辑主语是一致的，be awarded的主语是Mo Yan，A是莫言的多年努力，B是家乡的人，C是现在的网络评价，都不对，句意：被授予诺贝尔文学奖后，莫言觉得他多年的努力没有白费。选D。
