1937年秋，作者跟随俄克拉何马州的农民流浪到加利福尼亚。他沿途见到流浪的农民处于绝境，感到非常震动：“有五千户人家快饿死了，不光是挨饿，是快饿死了”，“问题非常尖锐”。这时他觉得他过去写的书是“多么拙劣，多么渺小”。他要描写农民的悲剧，要为他们说话。这是他创作《愤怒的葡萄》的动机。

In the autumn of 1937, the author traveled to California with Oklahoma farmers. Along the way, he saw the vagrant peasants in desperate situation and was shocked: "there are 5000 families dying of hunger, not only starvation, but also starvation", "the problem is very acute". At this time, he felt that the books he had written in the past were "how clumsy, how small". He wants to describe the tragedy of the peasants and speak for them. This is his motivation for the grapes of wrath.<br>
