Initial response to language: 49.4% (38/77) of the infants hadresponded to the three factors at 8 months, including "their own name" "don't xx" "where is mom/dad".The proportion rose to 87.5%（35/40）at 15 months, and the infants had responded to all the three factors at16 months. Comprehensible short sentences: at 8 months, infants can understand approximately 7 short sentences, and at 16 months, they can understand 25 short sentences.
