For the current high school teaching, teachers need to master grammar knowledge and a certain vocabulary (about 6000), as well as the study of college entrance examinations over the years. The charm of teachers' lectures and the ability to communicate with students are very important. The vocabulary of CET-6 is about 5000, so you only need to know it, and there is no further requirement.
If you are studying teaching resources, I suggest you know the tenses of the three clauses and verbs first. When the vocabulary is insufficient, you can only recite TEM-4, and when you have enough time, you can only recite TEM-8. It is a good thing to constantly enrich yourself. Then brush the real questions over the years, whether it's Chinese or painting, the real questions are enough. There is no need to do simulation questions, and it is very important to analyze which test sites have learned.
