First of all, there are the following methods for words. The first is the frequency of strengthening memory, which means memorizing a few words in the morning and reading them again every few hours. In short, the memory interval within a day should not be too long, otherwise your hard-earned memory will fade with time. The second is to make up jingles according to your own understanding. For example, good morning is a dog touching you ... the third one. I suggest you memorize words in different categories and form a meaning group. For example, great importance means very, very much ... which is very beneficial to your writing. When writing, don't write some low-level words, but write high-level words, such as great importance, many of which are complicated or handy.
Secondly, it is grammar. To learn grammar, we must first understand what is subject-predicate object complement, what is copula, and what is direct object and indirect object, which are the basis of learning grammar. Grammar is a house, subject and predicate are sand bricks.
Finally, I suggest that when you read newspapers or do exercises, you will find good sentences and good vocabulary. You should copy them down. In the long run, your composition will improve. It should be noted that this improvement process may be slow, but in the end, you can get good results. I can guarantee that the previous 25-point composition is at the level of 2 1-23, relying on my mastery and accumulation of grammar. My personal understanding is that when your grammar is basically correct, your composition should win by vocabulary, because at this level, everyone's grammar is similar, nothing has changed, the only thing that has changed is your vocabulary! For example, many people use a lot when they think of "a lot", but don't forget many A's; Handsome; Huge, countless; Many people write expert when they think of "expert", but few people think of specialist. Many people write "good at" when they think of the word "good at", but they don't know that there is a higher expression: good at or good at ... master and mediocrity are reflected in these subtle differences.
I do it my way. From the post-90s generation of senior one to the college entrance examination 129.
I hope it helps you.
