1, English. I think the most important thing in English is words. If I can't even learn words, how can I continue my study? So you can remember as many words as possible. Also pay attention to the changes of various word forms, and you can try to make sentences yourself. Then there is grammar. Grammar is the rule for you to learn a language, so you can buy a grammar book. You don't have to memorize all the above terms, just look through them when you are free and remember some key sentence patterns. In addition, you can also buy a copy of New Concept English 2 (New Concept 1 is a junior high school, and most of the contents are learned in textbooks), and you should also remember the words of New Concept English 2. The content of the above text is relatively long, so you shouldn't be able to recite the whole text, but you can recite some good sentences, such as complex sentences. In addition, New Concept English 2 has some notes at the back of the text, which are some grammatical points. You can also have a look. In addition, New Concept English Self-study Guide 2 has a detailed analysis of the words in each lesson, such as collocation, sentence making and text content analysis. If you have a weak foundation, you don't have to buy it.

2. Mathematics High school mathematics is very different from junior high school mathematics, and high school mathematics cannot be limited to textbooks. The concepts in the textbook should not only be memorized, but also understood. I can say that 90% of the exercises in the textbook are basic questions, and such questions are hardly tested in the unified examination and college entrance examination. Both the college entrance examination and the college entrance examination come from textbooks, but they are higher than textbooks. If you can't understand a concept, you can't do it. In addition, high school mathematics is closely linked. If a link is broken, it will become a big problem in the future, and it should be consolidated in time. If you have time now, you must understand the concept carefully and do some typical exercises. Don't just look at simple topics and don't do it. If you only look at the topic for a long time and don't do it, your hands will be rusty, and mistakes such as clerical errors will easily occur when you take the same topic in the exam. When school starts, you will find that the math teacher is very fast in class. You have to take two compulsory books in the first semester of senior one, and you can imagine the speed. You don't have the energy to study math for a long time.
