the scorching sun,with sweat dripping down onto the ground. This allows readers to directly feel the difficulty of farmers work.The lines "No field is left uncultivated throughout the land,Yet farmers still starve to death.deeply reveal that even though farmers work hard to cultivate the land and leave no field idle,they still cannot escape the tragic fate of starving.This shows the poet's deep sympathy for farmers. Criticism of social injustice:Through the contrast between the hard work and the tragic ending of farmers,the poet criticizes the unreasonable social system at that time.Farmers work hard all year round but do not have enough to eat,while those who do not work enjoy the fruits of farmers'labor. Advocacy for cherishing food:The line "Who knows that every grain in the bowl is the result of hard work."frankly and profoundly warns people to cherish every grain of food because they are all exchanged for the hard-working sweat of farmers. This reflects the poet's respect for the fruits of labor and his good intention to guide people to establish the awareness of saving food through poetry. 学案20 Using Language(2) 品篇悟道 Task 1 Lead in Omitted.
