Vocabulary not only affects reading and writing speed, but also affects listening effectiveness. Linguist Terral believes that as long as they master enough words, foreign language learners can better understand foreign languages ??and express themselves in foreign languages ??even without much grammatical knowledge. Research by American linguist Diller also shows that if we know 25 words, on average we know 23 words on each page; if we know 135 words, the percentage reaches 50; 2500 words is equivalent to 78; 5,000 words corresponds to 86; 10,000 words corresponds to 92. Moreover, linguist Wilkins has a classic saying: "Without grammar, little information can be conveyed, and without vocabulary, nothing can be conveyed." Therefore, students with a larger vocabulary can understand less in their reading comprehension. The more, the greater the accuracy, the faster the writing speed, and the better the listening effect. For the CET-4 and CET-6 exams, the vocabulary required by the syllabus is more than 4,200 and 5,500 respectively, so everyone must be prepared before going to the examination room to ensure that they have sufficient vocabulary reserves.
