普通儿童的词汇量有多少？
一般来说，孩子在 20 个月左右就会开始使用他们的第一个单词，到 3 岁时，他们通常会有大约 1000 到 1200 个单词。
Around the age of 4, they usually have between 1500 and 1600 words, and this vocabulary increases as the child learns more words.
It is worth noting that the size of the vocabulary can vary greatly from child to child and can be influenced by many factors, such as the way they communicate with their parents, the books they read, the television they watch or the frequency of social interactions.
