大家说说看自己的单字量有多大? 回复 2# huazai1984 it is very easy to know how many words you have. take a dictionary, for instance, oxford with 50,000 words inside. then pick 100 words randomly. if you know 20 words, you know 20x(50,000/100) = 10,000 english words. this is a rough figure depending on your sampling. the more your sampling is, the more accurate the figure is. try it and you will know. 查看更多
