High scores for some junior high school review materials, questions

Hello Introduce an efficient study method to you: list your strengths, weaknesses, and stable subjects!

Qiangke: 30% of the time

Stabilization section: 30% of the time

Weak department: 40% of the time

Because the exam-taking exam is about the total score, you should pay attention to some courses with a large development score!

Learning is a gradual and gradual process, and Chirome should persevere, and also take the initiative to communicate with teachers or classmates.

Thank you for your question, and I wish you the best of luck

For physics and chemistry, to understand sexual memory, it should be that these things have a pattern to follow. For example, in physics, as long as you really understand a problem, you will have a systematic thinking about solving this kind of problem, and as long as you have an idea, there is basically no problem with this problem. As for politics and history, my suggestion is a systematic review.

Each historical event is not independent, they are internally linked. So you should take the chapters as a unit, connect the events and ideas of each chapter, and remember or bury it should be able to do more and more often, you can try it, I used to do this, and the results are not bad, but the learning style also varies from person to person, I hope this method will work for you. Since my English and language are relatively poor, I won't talk about it!

If you see it too late, it's useless.

Chinese: It is recommended that you buy the "Handbook of Basic Chinese Knowledge" published by Xue Jinxing, and then go to the bookstore to pick a book to read and practice, and write a modern and classical Chinese text every day, and your language will reach a new height in the long run.

Mathematics: Now you can do "Double Speed" and "Dial", and you must lay a solid foundation in mathematics for the ninth grade! The review of the high school entrance examination is to buy the compilation of questions from the provinces of last year's high school entrance examination, and now many mock questions on the market are not very formal, which is really misleading!

Although the questions in the high school examination will not be taken again, in the process of doing the high school examination questions for a long time, you will also find out some rules for the questions, such as the calculation of quadratic functions, how to add auxiliary lines of circles, and similar applications, ......You don't even need to count the whole process when you look at the problem (similar to our high school analytic geometry).

English: The same language, because it is a language, it is impossible to go up in the short term. It is recommended that you do a little bit every day in each of "5.3" and "Reading Comprehension and Cloze in the Blanks", and the key is to persevere!

Physical Chemistry: It is highly recommended that you take a look at the "Successful Study Plan" and "Dictionary Point", you can buy "5.3" for the review of the high school entrance examination, or you can buy "Compilation of Test Questions", and the same as mathematics, the high school entrance examination depends on the immediate score, you must learn well!

Other liberal arts: memorize it every day and finish the tutorial book issued by the school.

By the way, maybe many of your classmates now are focusing on the endorsement of liberal arts, but the grades will be very good in a short period of time, but we must take a long-term view! I was among the top 30 in the city in the high school entrance examination because I had a solid science subject in the ninth grade. Don't pin your hopes on the total review, if you think about it in just a few months, you have to review the knowledge for three years, how can it be like a class to give you a detailed review, the teacher will give you a knowledge network, relying on your basic skills.

So, friend, I'm glad you recognize now that you need to review in advance. As for Chinese English, it can be said to be the nirvana of the ultimate PK for honor students! In the end, everyone in the liberal arts is about the same, and the top students in the science are also evenly divided, and at this time, it is the Chinese and English to pull the scores, so don't ignore it.

Because I have just entered my ideal high school, I am really touched by the questions about the high school entrance examination now, and I really want to help my younger students!

I wish you the best of luck in your dream high school, and I hope you will bring me good news next summer!

1. In the third year of junior high school review, you must learn to sort out your own learning situation, based on textbooks, combined with your own notes, test papers, weak links, existing problems, etc., allocate time reasonably, and tackle and implement them little by little in a targeted and specific way. If you don't grasp much content, spend more time, and when reviewing, you should be systematic, don't go east and west, and in the end you don't review anything well.

2. You can learn to master the ability of speed reading and memorization, and improve the efficiency of learning and review. Speed reading and memorization is an efficient learning and review method, and its training principle is to activate the potential of "brain and eye" and cultivate the formation of eye-brain direct reflection reading and learning mode. For the practice of speed reading memory, see "Elite Special Whole Brain Speed Reading Memory Training", practice with software, more than an hour a day, a month's time, you can double the reading speed, memory, comprehension, etc., and finally improve the efficiency of learning and review, and achieve good results.

If your reading and learning efficiency is low, you can practice it well.

3. Learn to integrate knowledge points. Classify the information you need to learn and the knowledge you need to master, and make it into a mind map or knowledge point card, which will make your brain and thinking clear and easy to remember, review, and master. At the same time, learn to connect new knowledge with what you have already learned, and constantly integrate and improve your knowledge system.

This promotes understanding and strengthens memory.

4. Question practice: Problem practice is indispensable, but don't blindly make a mess of yourself by blindly using the tactics of the sea of questions. When doing the questions, resolutely complete them independently, eliminate plagiarism, and eliminate the tactics of the sea of questions.

You will never be able to finish the test questions, but the question types are limited, so you must learn to reflect, categorize, and sort out the corresponding solution ideas. When you encounter the wrong questions (carelessly do it wrong, you can't do it), it is best to collect these wrong questions, and each subject has an independent set of mistakes (the set of mistakes should be classified), and when we review before the exam, they are the key review objects to ensure that there are no more mistakes and points on the same questions.

In the review, you should also learn to summarize in stages, understand your recent learning, and adjust and improve.

I don't know if you're a ** candidate, if you review the paper, the local model and the second model are very good, you can go to the bookstore to buy it or have it online, and the high school entrance examination network is relatively complete. There is also a special volume on it

Go buy one. Bookstores are everywhere.

i.e. proof is required (ab+cd) =(b +d) (a +c ) while (ab+cd) -b +d (a +c ) = (a b +c d +2abcd) - (a b +a d +c d +c b )

2abcd-a²d²-c²b²

2（ad-bc）²

0 So (ab+cd) = (b +d) (a +c ) is proven.

For example, if you have three numbers x, y, z, you have to prove that y is the middle term in the ratio of x, z. Just prove y*y=x*z

For this question,,, because (b 2+d 2)*(a 2+c 2)=a 2*b 2+b 2*c 2+d 2*a 2+c 2*d 2

Because AD=BC , B 2*C 2=A*B*C*D , D 2*A 2=A*B*C*D, so (B 2+D 2)*(A 2+C 2)=A 2*B 2+2*A*B*C*D +C 2*D 2

ab+cd)^2

The original question is proven.

It's easy! Just put pen to paper and come out! First (b+d)(a+c) to get the equation a, then (ab+cd) to get the equation b, using the known ad=bc to compare the ab formula substitution to get a=b

It is known that ab + cd is the middle term of the ratio of b square + d square to a square + c square, i.e. (b square + d square) (ab + cd) = (ab + cd) (a square + c square) equation a square multiplied b square + a square multiplied d by d square + b squared multiplied c square + c squared multiplied d by d square = a square multiplied by b square + abcd + cdab + c squared multiplied d by d squared.

Because ad=bc.

A square multiplied by D square = ABCD = B square multiplied by C square.
