Examining emotional metaphors in picture books from the perspective of children has positive significance for children's social development and the improvement of picture book quality.Emotional metaphors in picture books include four aspects,i.e.,image metaphor,natural environment metaphor,text metaphor and role metaphor.Children's ability to recognize emotional metaphors in picture books is affected by their age and difficulty of metaphor recognition,and they have an emotional tendency to recognize emotions through emotional metaphors.Based on this,teachers should pointedly carry out emotional metaphor recognition training,and guide children to establish correct perspective of emotion,and picture book creators should design hierarchical emotional metaphors pointedly according to children's age characteristics in teaching activities;help children accumulate experience schemas and adjust the metaphor usage frequency.
