English grammar is filled with numerous rules, and memorizing them alone often leads to quick forgetting. Select classic sentences with clear grammatical structures. First, analyze the sentence patterns to understand how grammar points are applied, then imitate and create your own sentences using the same structures. For example, when learning the attributive clause, analyze “This is the book that I bought yesterday.”, and then write sentences like “She is the girl who won the first prize.”. Through extensive imitation exercises, you can become more proficient in using grammar.
