Language: 1. Understand and master some basic grammar knowledge, such as part of speech, sentence structure (subject, predicate, object, definite, form and complement) and several types of complex sentences. 2. read books and periodicals extensively to expand your knowledge. Readers, Bowen, short stories, reading and writing monthly, Chinese and foreign masterpieces, and a series of works by writers you admire. Be good at accumulation, not only reading, but also taking notes. Think about similar things in life. 4. Writing style is a person's facade. Buy a copybook and practice your handwriting. The online marking of the college entrance examination, and the beautiful writing problem-solving process displayed on the computer screen will give you a lot of points! Math: 1, further study junior high school related knowledge. For example, factorization of quadratic trinomial, cubic and cubic difference formulas, complete square sum cubic formula, image properties of quadratic function, formula for finding roots of quadratic equation with one variable, Vieta theorem (the relationship between roots and coefficients), plane geometry and so on are all commonly used knowledge in high school learning. If you do this well, you can win the starting point of high school. 2. Strengthen the computing power. Senior high school mathematics requires much higher speed, accuracy and precision than junior high school mathematics, and it is also a kind of ability that the college entrance examination focuses on. It is necessary to improve the computing ability through intensive training. 3. Preview the math textbook for senior one. Have a general understanding of the content to be explained in high school, set is the starting point of the whole high school, and function is the key and difficult chapter in high school, so we should think deeply about the textbook, try to understand the concept from different angles and experience the learning method of the concept; Through after-class exercises and skillful use of theorem formulas, the passive learning method in junior high school is gradually transformed into active learning in senior high school. 4. For students with weak math foundation, they should use their vacation time to make up math, so as to lay the necessary foundation for high school math learning; For students who have advantages in mathematics, we should also pay attention to continue to improve their mathematics literacy, and we should not take it lightly. English: Vacation suggestion: Vacation is a good opportunity to improve your English! Develop several good habits of language learning: 1) The habit of active reading. Make good use of holidays, don't relax English reading, increase reading volume and improve reading speed, otherwise it will be difficult to adapt to English learning in senior high school. The content can be English newspapers or magazines used by middle school students, simple English reading materials, etc. At the same time, make reading notes. 2) The habit of self-testing. You can look at some simple high school exercises in advance to understand the main questions, especially the new questions such as pronunciation, composition correction and written expression. Do a good job in the connection and transition of junior and senior high school knowledge. 3) Summarize the habit of special topics. Summarize and review junior high school knowledge in the form of special topics. Review the past and learn the new. 4) The habit of getting up early and reading aloud. Say it out loud, read it out loud, enjoy yourself and revel in it. 5) The habit of listening to English radio, English songs and watching English programs. 6) The habit of using English at any time and thinking in English. For example, keep an English diary and talk with friends in English. Holiday task: 1. Insist on reading two English articles every day, which can be good articles in junior high school textbooks or 2 or 3 volumes of New Concept English. 2. Persist in reciting an article every day (Book 2 of New Concept English) to enhance English language sense, which is very important in senior high school English learning. 3. Pay attention to make up for the weak foundation of pronunciation and grammar, otherwise it will cause classroom obstacles and seriously affect senior high school English learning. 4. Organize and review the vocabulary learned in junior high school. After school starts, we will organize reading competitions, reading competitions, recitation competitions, vocabulary competitions, calligraphy competitions and so on. Look forward to the wonderful performance of the students! Necessary tools for English learning: Oxford or Longman English-Chinese Advanced Dictionary (electronic dictionary is not allowed), copybook (four lines), and error-sorting book. Physics: 1. Reorganize the knowledge of junior high school physics and summarize the knowledge points and corresponding physical formulas in each chapter. 2. According to the textbook and the physics review materials of Grade Three that I have been saving, I will seriously study the problems of liquid pressure, buoyancy, circuit (especially the characteristics of series-parallel circuit and simplification of circuit) and the knowledge of force analysis, and then review it at least once. I must make this part of the exercise done in grade three clear. (This part of high school no longer talks about basic knowledge, but it is often used, and the college entrance examination is also involved. ) 3. Borrow a math textbook from the first volume of senior high school to learn trigonometric functions independently. This part of knowledge has not been learned in junior high school, but it is often used in the first section of senior high school physics, which is the necessary knowledge to learn senior high school physics well. Borrow the first physics textbook for senior high school to preview and do some exercises after class. Have a general understanding of the concepts and formulas in the textbook. There are some small experiments in the textbook, which we can do by ourselves. We can try to do it ourselves, from which you will feel the mystery of physics. In the first half of senior one, we mainly completed the first four chapters, which is a very critical period for the introduction of physics. Compared with junior high school, the content of physics learning in senior high school has greatly increased in depth and breadth, and the physical phenomena studied are more complicated. When analyzing physical problems, we should not only start with experiments, but also establish physical models to explore problems from many aspects and levels. So we should do a good job of preview. By reading books or searching online, you will find that physics is so closely related to our life, and the physical world is so mysterious, profound and colorful. Dear students, take action, and the road ahead of you will get wider and wider! Chemistry: 1. Reorganize the knowledge learned in junior high school chemistry and summarize the knowledge points in each chapter. 2, access to information, master the laboratory preparation methods and chemical properties of H2, O2 (three methods) and CO2; Summarize the use and safety precautions of commonly used experimental drugs in the laboratory. 3. Skillfully write out all the chemical equations in the first and second volumes of junior high school textbooks, and write them in a book for the school to check. 4. Memorize the symbols and atomic structure diagrams of the first 20 elements; 5. Memorize the valence of common elements and their atomic groups, and combine chemical formulas according to the valence. 6. It is necessary to master the content of the lightest gas in the expansion question of junior high school chemistry on pages 65-67, which needs to be linked with senior high school chemistry. Remember, whatever is in junior high school textbooks, no matter whether the senior high school entrance examination is taken or not, is no longer taught as a new lesson in senior high school. Therefore, the knowledge in junior high school textbooks must be learned, especially the content that is not tested in the senior high school entrance examination. 7. Consult new textbooks online, (PEP) requires 1. Students who can't surf the internet will borrow the first chemistry textbook 1 that graduates must have, preview it and do a lesson after class. In the process of preview, we can take a look at the teaching materials in general, mainly to grasp what high school chemistry is as a whole. If you want to learn chemistry well, the key is to learn chemistry well on the basis of understanding, to be willing to work hard to remember, and to carefully imprint what you have learned in your mind. Experiments are the most attractive in chemistry, full of interest and creativity. We must carefully preview and think about the inquiry experiment of teaching materials. 8. Keep the junior high school textbooks and bring them after school starts. Some knowledge of high school needs to be returned to junior high school textbooks, and so does the college entrance examination. Biology: 1. Review the knowledge in junior high school textbooks and make a good connection with the knowledge in senior high school: ① cell structure ② use of microscope ③ photosynthesis ④ cell respiration 2. Borrow the first textbook of biology required by last class and preview it briefly, especially the knowledge point of "protein" in the second quarter of Chapter 1-compounds. 3. Discuss the experience and good methods of learning biology well with seniors in senior three. Pay more attention to the development of biology when you have time to surf the internet, and some knowledge in high school is closely related to it. Have the opportunity to participate in social practice, get close to nature and gain perceptual knowledge. Politics: we can't wake up without money every day, but you don't necessarily know its development process and issuer; We have seen a wide range of goods in the mall, but you may not be able to sum up its meaning in one sentence; We are all experiencing the impact of the financial crisis, but you may not know its causes, harm and solutions; We can find that the price of a commodity fluctuates in the market, but you may not know the reason; People often say that "shopping malls are like battlefields".

You must have heard of CEO, and you may have thought about becoming CEO, but do you know what qualities you must have? People often say that this government is people-oriented. Do you know what measures they have taken? After the Wenchuan earthquake in Sichuan, the whole country donated money and materials, and the state finance invested tens of billions. Do you know what it will do? Things are unpredictable, and international relations are ups and downs. Can you judge right from wrong? Students, act quickly, we will clear the fog and solve the mystery for you. Interest is the best teacher. I hope you can read more newspapers, pay more attention to the news, pay more attention to and observe the economic, political and cultural phenomena in your life, and ask why, so that you can get started faster and learn better than others. We believe: you must be the best! History: Summer is hot, do you want to swim in the long river of history? Do you want to feel the prosperity of China in ancient times, the weakness of modern times and the rise of modern times? Do you want to appreciate the beauty of omnipotent and eternal romantic figures? ..... High school life is beautiful, and we are willing to open the door of wisdom with you and write a brilliant life. Here, send our little suggestion: 1. Reading junior high school history textbooks lays a solid foundation for senior high school history learning. 2. Understand the difference between junior high school and senior high school history study from the high school students you know, so as to complete the transition from junior high school to senior high school study as soon as possible after school starts. 3. You can watch some TV programs and history books related to the history of China; You can also browse and read some pictures of places of interest and historical anecdotes at home and abroad. To improve your interest in history. Geography: In today's world, global problems such as resource shortage, environmental change, population explosion and unbalanced development are increasingly acute. In order to meet these challenges, we need to learn geography, so as to cultivate the ability to understand and deal with these problems, establish modern concepts such as adapting to local conditions, fostering strengths and avoiding weaknesses, globalization, sustainable development, and harmonious coexistence between man and nature, and acquire the basic ability to deal with some major problems in the future. So before you enter the balance, you should pay attention to: 1, pay attention to life and current politics. Geography is a subject closely related to life. Geography provides explanations and answers for Scientific Outlook on Development, the coordination between man and nature, regional coordination and talent strategy. Pay attention to watching the weather forecast of CCTV every day. Understand weather symbols (such as sunny, cloudy, light rain, heavy rain, thunderstorm, wind direction, wind force, etc.). ); And pay special attention to the development and changes of important weather systems (such as typhoons); Understand the geographical location and weather conditions of the provincial capital. Sort out the places you have been in the summer vacation and get to know the famous mountains and rivers of the motherland.
