First, solid basic knowledge mainly depends on listening to the teacher carefully in class;

Second: rich experience in doing problems mainly depends on doing more homework and exercises after class;

Third: active thinking change, mainly thinking about the problems encountered, changing the way of thinking and doing problems, and reading more books to exercise thinking;

Fourth, to improve reading comprehension, many points are lost because of not correctly understanding the topic, so to improve reading comprehension depends mainly on solid language.
