Linguist TERREL 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. (I seem to have seen countless scenes of elementary school students throwing grammar books angrily) But!! Linguist WILKINS has a classic saying: "Without grammar, you can only convey very little (note that it is very little) information, but without vocabulary, there is nothing." It can't be conveyed either," according to research by American linguist Diller.

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; 5000 words Volume corresponds to 86; 10,000 words corresponds to 92.

\So, students with a larger vocabulary can understand more parts in reading comprehension, and their accuracy will be greater. For the CET-4 and CET-6 exams, the vocabulary required by the syllabus is 4,500 and 6,000 respectively. Considering that the shady teacher wants to frame everyone's psychology, you must prepare enough vocabulary before going to the examination room.

The main task of memorizing words is to solve three types of words, nouns, verbs, and adjectives. But nouns can actually be described. The operation method is: functional descriptors and attribute words. For example: the correct term for "gunpowder" in Level 6 translation is gunpowder. But if you didn’t get a score before the exam, don’t worry. It can be described as blasting (explosive function) powder (property is powder). In reading comprehension, if you encounter a word you don't know, just understand it as something like that and continue reading. Moreover, in reading comprehension, unknown nouns can help with positioning.
