Until 10-year-old, the ability of children’s interpretation of irony phenomenon were still developing；（2）Intonation （neutral or stressed） affected the attitude detection and meaning detection of children, but had no effects on language phenomenon detection of children；（3）the children’s cognitive levels of different types of irony were different. There were not noticeable differences between 6-year-old children’s interpretations of two types of irony, but there were striking differences between 8-year-old and 10-year-old children’s interpretations of two types of irony. Compared with ironic compliments, 8-year-old and 10-year-old children could interpret ironic criticisms better.
