(Laying a good vocabulary foundation is the central task. Choose any six-level vocabulary book and make a recitation plan that suits your strength. In terms of new words, there is not much difference between the sixth grade and the senior high school level. However, the sixth-level vocabulary has increased to a certain extent, and the efficiency and strength can be strengthened as appropriate. When memorizing words, it is necessary to specially train the ability of "visual objects". There is no need to deliberately emphasize spelling and compound meaning, as long as you keep flipping through the book or repeating your understanding to strengthen your impression. The most difficult thing about memorizing words is to persist in a short-term repeated cycle. If you can read it for a while, you'll beat your old self.)
