給大家看一些2013年test your vocabulary網站的調查數據:
Most adult native test-takers range from 20,000–35,000 words
Average native test-takers of age 8 already know 10,000 words
Average native test-takers of age 4 already know 5,000 words
Adult native test-takers learn almost 1 new word a day until middle age
我們需要了解的信息是:
8歲英美兒童的平均詞匯量是1萬詞(包括聽力詞匯)
4歲英美兒童的平均詞匯量是5000詞(都是聽力詞匯)
再看一些數據:
Native adult vocabulary size appears to be principally determined by reading habits between ages 4 and 15
For native vocabulary growth, reading fiction specifically is just as important as reading in general
Native test-taker children who read "lots" learn 4 new words a day
Native test-taker children who read "somewhat" learn 2.5 new words a day
Native test-taker children who read "not much" learn 1.5 new words a day
從這些數據中,我們了解到的信息是:
在4-15歲時的閱讀量與成年人詞匯量具有最大的關系
看圖:
閱讀量大的孩子11歲已經知道18000詞
13歲兩萬詞
