What does the phrase “Fields of Gazing Grain” symbolize?
【正确答案】：

IT SYMBOLIZE THE MATURE PERIOD.

【题目解析】：引文选自艾米丽迪金森的《因为我不能停步等待死神》。诗中的“strove”暗示着年少时的活力，充满对童年时的热爱，所以“School”指的是上学时候的青少年时代。“gazing”（若有所思，带有感情的注视），暗示着对盛年的收获倍感珍惜，“the Fields of Gazing Grain”本意为一望无际的麦田，在这里可以引申成成熟，收获的季节，所以代表的是盛年时代。“the Setting Sun”本意指落日，在这里象征着老年时代。
