American linguist Diller's research shows that if you know 25 words, you will know an average of 23% words per page. If you know the word 135, the percentage will reach 50%; 2500 words is equivalent to 78%; 5000 words corresponds to 86%; 10000 is equivalent to 92%.

Therefore, the more words students master, the more they can understand in reading comprehension, and the greater the correct rate.
