Vanguard inscription under seventh grade mathematics
From the grade stage:

The first grade is the initial stage of learning adaptation. In primary school, memory is the main part, and listening is the main part. The junior middle school stage is based on understanding and needs to be mastered on the basis of understanding. If students can't complete the transition from primary school to junior high school well, they can't learn well in Grade One and can't keep up with Grade Two.

Freshmen in senior one should preview new lessons, adapt to the learning state of junior high school as soon as possible, and cultivate their own learning habits and methods.

The second day is a critical period of transformation. This year is a watershed between learning well and learning badly. If you learn well in the second grade, you will learn well in the third grade. If you can't keep up the next day, it will be much more difficult to improve on the third day.

Junior two students should strengthen the review of old lessons and the preview of new lessons, and learn new ones through the review of old lessons. They should also effectively check and fill in the knowledge points of the last school year, and focus on cultivating their learning ability on the basis of paying attention to their learning methods and habits.

The third grade is a key turning point. Whether the senior high school entrance examination is good or not largely determines the future direction.

In addition to mastering knowledge points, it is particularly important to consolidate basic knowledge in grade three, especially sprint counseling before the exam.

Generally speaking, this course:

1 read more new words in Chinese, and the basic score is good! Don't read roughly in reading comprehension! Intensive reading! Don't be too hasty when answering questions! Pay attention to the score! Try to answer more with divergent thinking and be organized. The composition should stick to the theme and be good at refining the theme! For example, it takes about three lines to find the main point at the beginning of the narrative. Then divide the paragraphs according to the topic. This is the skill.

Mathematics pays attention to basic knowledge, and exams are inseparable from textbooks. Understand the textbook, exactly. In addition, do more original works. Improve your ability.

3 history and politics should be crazy, and it is best to compare with others!

4 English should be recited crazily! Recite a few more English essays on different topics for reference during the exam.

Second, how can junior high school students improve their math scores? How to improve junior high school mathematics?

(1) interest

It is said that interest is the best teacher, and the most important thing is to be interested in mathematics. If you are tired, you can't keep it.

(2), understanding ability

Mathematics is a science, and understanding ability is very important. Without understanding ability, your math and even all science studies will be very difficult. However, the cultivation of understanding ability is very difficult. You must try to understand some philosophical theories and relatively abstract mathematical models that are difficult for you. The simplest training is also very difficult, so for a moderately difficult question, it is necessary to see that the auxiliary line can reflect its practice within 1 minute. Secondly, we should not only understand what the teacher said, but also try to figure out the specific mental process when the teacher did the problem. This is the basic ability of many people to learn mathematics well.

(3) diligence

I met many students who worked hard but still couldn't learn science well. The dumb thing about the math exam is that it is easy to pass as long as you study hard according to the teacher's requirements, but it is far from enough to get 145 by the teacher's practice. Even poor students still have simple and easy learning methods. Only by mastering the correct methods can we gain something through diligence.

(4) Method

1, geometry

Geometry learning is the most skillful for students at this stage. Let me introduce the trick of learning (solving) geometry problems.

(1), remarks

In geometry class, students should not only learn to take notes and extract blackboard books, but also sort out the basic graphics involved in the teacher's lecture after class. What is a basic graphic? The basic figure is similar to the method of adding common auxiliary lines when we do geometry, except that the basic figure is a complete figure after adding common auxiliary lines. How to filter basic graphics? In fact, it's very simple. Combine the homework of the day, sort out and screen, find out similar auxiliary line addition or similar problem-solving methods, and sort them into the attributes of basic graphics, that is, all the conditions and proof methods that basic graphics can prove. This is a long-term process, but it will make you think hard when solving geometry problems after memorizing basic figures and their attributes, with high accuracy and efficiency.

(2) Steps to solve the problem

First read the topic and express the known conditions on the geometric diagram (preferably on draft paper). Secondly, when doing the proof, show the known conditions and verification conditions on another diagram. At this point, when the topic is relatively simple, you can solve the problem directly, saving time. However, if the topic is complicated and you can't figure it out in 10 minutes, try to combine the two pictures and try to connect the conditions between the two pictures through auxiliary lines until you draw an auxiliary line to prove it.

Choose the right method to do evaluation questions. To solve the area problem, we should skillfully use the properties of basic graphics or directly combine them with known data through graphics similarity, congruence, translation and rotation, and calculate all conditions that can be proved directly or indirectly as much as possible, plus appropriate auxiliary lines. The cultivation of this ability needs a large number of proof questions as the basis for solving problems easily.

2, algebra and rational number, irrational number operation

(1), summary formula

In class notes and homework, sort out the equivalence relations with high occurrence rate and deduce them by yourself.

(2) Memorizing formulas and typical examples

Similar to the endorsement of liberal arts, the effect of understanding memory is better

(3) the method to solve the problem

First, simplify the known relationships and find out all the equivalent relationships that can be found.

Secondly, the connection is sought or proved to be deformed and the equivalence relation is found out.

Using appropriate formulas, backward derivation or ingenious methods to solve or verify, the basic idea is the same as geometry, and it also needs usual accumulation.

3. Other issues

The basic ideas of other questions are basically the same as those of geometry and algebra mentioned above. I believe that after skillfully using the learning method of geometric algebra, students will certainly be able to sum up their own set of thinking modes and achieve good results in the basic learning of mathematics.

(5) Promotion (please implement it on the premise that the Bank has spare capacity.

1, special exercise for senior high school entrance examination

Practice the mid-term exam questions related to the questions you have learned properly, don't rush to achieve success, and read all the lines: the information recommends the Orsay deep-water bomb. Don't think too difficult a problem, just do an example.

2. Synchronous learning of Olympic mathematics

Buy one or two synchronized Olympic math books for self-study, and ask teachers or classmates questions if you don't understand. For most students, you can't study in advance, and you can't ignore the importance of normal homework.

3. Students who have too much spare time can take part in Olympic math classes or competitions as appropriate. Don't ask for awards, but focus on participation.

Third, how to improve junior high school composition? How to write a junior high school composition? How to write a good composition for junior high school students.

(A), the composition should learn to accumulate

The ancient summaries of "Reading thousands of books, writing like a god" and "A clever woman can't cook without rice" illustrate the importance of "accumulation" in writing from both positive and negative aspects. "Usually rely on accumulation, the examination room depends on play", which is the same experience of the students in the examination room.

1. In terms of language, a "glossary" should be established. Vocabulary is the cell of an article. Vocabulary in a broad sense refers not only to the collection of words and phrases, but also to sentences and sentence groups. There are two ways to establish "vocabulary": the first is reading. Usually, you should read books, newspapers and periodicals extensively, take reading notes, extract some beautiful words, sentences and paragraphs from a specific notebook, or make reading cards. The second is life. At ordinary times, we should capture the fresh language in the popular spoken language and write it down in a small notebook or card that we carry with us. Over time, we can say it chapter by chapter and write it beautifully.

2. Strengthen the accumulation of materials. Materials are the flesh and blood of the article. Because many students usually don't pay attention to accumulating materials, they are worried every time they write a composition, or edit or copy it. The solution to this problem is to accumulate materials. Usually, you can take a video camera and tape recorder with you, observe life deeply, actively participate in life, and record your experiences in family life, campus life and social life in time in the form of sketching, keeping a diary and writing observation notes. When recording, we should grasp the details and the characteristics of people, things, things and scenery. The article written in this way is flesh and blood.

3. Strengthen ideological accumulation. Opinion is the soul of an article. The center of the article is not clear, or the thought is not profound, which often shows that the author's thought is superficial. Therefore, it is necessary to establish a "think tank". There are two ways: first, be thoughtful. "One more miss, one more gain." Think deeply at ordinary times and ask "why", "what" and "how" when something happens. So you can see the essence through the phenomenon. It is also necessary to record the "sparks" of thinking and the conclusions of thinking at any time. The second is compilation, that is, extracting famous sayings and aphorisms.

In short, the composition should be accumulated, and the three writing warehouses of vocabulary, material and thought should be regularly counted, sorted and classified to continuously enrich and expand.

(2) Learn to observe before writing a good composition.

Mr. Lu Xun emphasized two points when answering the question of "how to write good articles" for young artists: one is to read more books, and the other is to practice more. Here, "seeing more" means observing more. This shows that in order to write a good article and master skillful writing skills, it is necessary to observe more and learn to observe, and observation is the necessary premise and foundation of writing.

Russian novelist Chekhov earnestly warned beginners: "A writer must train himself to be a keen observer and never give up! -It is a habit to exercise your own observation, as if it were second nature. " It takes time to hone observation into habit and second nature, which is very useful and remarkable.

Pay attention to the people, events, sights and things around you, and hunt for the materials needed in the composition: be interested in some seemingly insignificant but meaningful things, and pay attention to the cause, process and result of things; You should pay attention to how the plants in the campus flower beds change their colors all year round, and learn to get to the bottom of it and find out the ins and outs of these changes; You should go out, enter the society, meet more people, observe their words and deeds, think about some things, and integrate into your own thoughts at any time. This is the process of observation, and the following points should be paid attention to in the process of observation:

1, observation should never be limited to "eyes". Broadly speaking, more practical observation refers to mobilizing all the five senses of people: listening with ears, feeling with the body and, more importantly, thinking with the mind, so that the observation will be more delicate and profound.

2. Pay attention to the use of "bad writing" in the observation process. As the saying goes, a good memory is better than bad writing. Many students see a lot and think a lot every day, but they are not good at writing it down at any time, which will waste the observed materials and a lot of valuable things.

3, observation should pay special attention to perseverance. Don't make "brain fever". Three minutes of heat is not conducive to writing a good composition. You should observe life and think about every day in your life, so that you can write wonderful articles.

Learning to observe plays a great role in laying the foundation and promoting a good composition. Without observation, you often find it difficult to write. May you learn to observe, constantly cultivate and improve your ability to observe, and make great progress in your writing practice.

(3), Italian high, Wen Sheng.

Intention is to establish the center and intention of the article. So what problems should the article pay attention to when expounding ideas?

1, the idea should be correct.

Correctness is the first meaning of the article. The so-called correctness is to ensure that the feelings and thoughts of the article are correct, in line with the nature and laws of objective things, in line with China's basic political principles, in line with people's basic moral requirements, and can give people positive inspiration.

2. Be single-minded.

"The problem of composition is more expensive than being single. Specialization is fine, and dispersion is stupid. " No matter how complicated things are, the main idea cannot be dispersed. An article should explain both this problem and that point of view, and it is ambiguous to ramble. In fact, if you want to cover everything, it is definitely not in place. Moreover, an article can only have one center. Instead of "biting off more than one can chew", it is better to concentrate on expressing a center with pen and ink. Even if we express the center through several things, we should stick to the center, keep the same goal, pay attention to the combination of materials and centers, and let all the forces contained in materials point to the center.

3, the idea should be novel

The article is the most taboo to echo others' opinions, and the novel angle is the core of composition innovation. The novelty of the idea requires jumping out of the old box and not following the advanced thinking, habitual thinking or the original psychological formula, but examining the alternative content contained in the topic from a unique perspective to avoid what others often write and what others have not written. Even if the same writing object can always be cut in from multiple angles, as long as we break the mindset, stand at the height of the times, avoid "vulgarity" and seek "difference", think from multiple angles and sides, or associate, expand, analogize or reverse, and build your most beautiful rainbow in the colorful sky.

4. Be profound.

Profound conception means that the established theme is not the superficial truth that people are familiar with, but to look at the essence through the phenomenon and dig deeper meaning.

5, the idea should be clever

In limited words, if you want to express profound thoughts, you can only see the world from a grain of sand, reproduce the whole picture of life from one branch and one leaf, and describe and think about society and life from one drop, one fragment, one moment and one phenomenon, that is, you should focus on the big picture and put pen to paper in a small place, but you can see great dullness from a small angle.

(4) How to write a good article about things

How to write a good article? Please remember the following five points:

1, indicating the source.

Introducing the history of the article in one or two sentences at the beginning of the article naturally leads to the following.

Step 2 describe it in detail

Through color and modeling, the shape of the article is accurately outlined, and the characteristics are written, giving people a distinct feeling. Use some appropriate rhetorical devices to develop a reasonable imagination. Give it emotion, and it will make things on paper come alive.

3, dynamic and static combination

Write the static shape characteristics first, and then write its dynamics. This will add some interest and the articles written will be more vivid.

4. Interpretation function

Each item has its own unique function. Generally speaking, this kind of article should explain the function of the article at the end, which will highlight the characteristics of the article.

5, into the feelings

Between the lines, it is necessary to reveal the author's love and cherish for the things described, which will enhance the appeal of the article.

Fourth, how to improve junior high school English?

For students with different grades in senior, middle and junior grades, the measures are different.

For students with high scores, the content of the textbook is simple and has been mastered, and they are often in a state of "not enough to eat". You can consider learning new concepts and other extracurricular content. Because there are often super-class contents in exams, a clever bird must fly first in order to remain invincible. Personally, I think that if children have enough self-control, they can buy books, tapes or CDs to teach themselves, which can save a sum of money. )

For students with average grades, the content of the textbook seems incomprehensible. They could recite it at that time, but they soon forgot it. On the one hand, we should increase the intensity of reciting, on the other hand, we can consider buying supporting exercises to improve our ability to do problems. When we do it, we don't look at the answers. After we finish writing, we should use red pen to correct it, and we won't ask the teacher in time. It is best to have two sets of questions in one unit. There are too few ordinary sets and too many four sets. )

For students with low marks, textbooks are like gobbledygook, and they often can't understand the meaning of Chinese. They can't read, recite and certainly don't understand. It is suggested to buy a teaching material supporting tape, read it first, then read it aloud, then recite it. If you can read and recite, your grades will naturally be by going up one flight of stairs. You can use an ordinary tape recorder or a repeater. The point reading machine is expensive and not very practical. It's easy to use a computer or a computer with Internet access. What kind of PDA is completely useless, and the role in this child's hand is often an advanced game machine. )
