"Dr. Ci's Private Lesson: English Verb Phrase Shorthand 420" is based on the verb phrases required to be mastered in the CET-4 and CET-6 examination syllabus (appropriately integrated into the content of the middle school stage and study abroad examination stage to meet the diverse needs of learners from preparation to development), and 350 commonly used ones are selected as learning content. Specifically, we learn 10 phrases in groups every day, and use the scientific "Three-step English Vocabulary Learning Method" throughout the whole process through guessing words to fill in the blanks, memorizing example sentences, and cloze filling. If users persist, they can see immediate language learning results after only one month of intensive training.
