The number of test questions was changed from 28 to 27, and the test time and test scores remained unchanged.

For example, the comprehensive geometric problem changed from three last year to two, but the difficulty coefficient remained unchanged.

① Test paper structure

The test questions were reduced from 28 to 27.

The number of questions is changed from 28 to 27, and the 28th question is cancelled, and the score of this question will be allocated to other questions.

The test time and test scores remain unchanged.

This year's exam instructions didn't say what the score ratio was for easy questions, medium questions and difficult questions.

Referring to the example of the problem, the geometric comprehensive problem has changed from three questions last year to two questions, but the difficulty coefficient has not changed.

② Examination content

Adjust 26 knowledge points

1. number: the basic method of rational number addition, subtraction, multiplication and division and simple mixed operation (mainly divided into three steps)? Change to? The addition, subtraction, multiplication, division, multiplication and simple mixed operation of rational numbers (mainly within three steps) was changed from "Understanding the concept of quadratic root and its laws of addition, subtraction, multiplication and division and Divison" to "Understanding the concepts of quadratic root and simplest quadratic root and its laws of addition, subtraction, multiplication and division of cubic root and Divison (under the root number)".

Change "square operation will be used to find the square root and arithmetic square root of some non-negative numbers and cube operation will be used to find the cube root of some numbers" to "square root and cube root of simple numbers, square operation will be used to find the square root and arithmetic square root of integers within 100, and cube operation will be used to find the cube root of integers (corresponding to negative integers) within 100".

2. Formula: delete "similar items", merge the meanings of similar items, and delete the meaning of factorization.

Change "explain the actual background or geometric meaning of some simple algebraic expressions" to "analyze the simple mathematical relationship of specific problems and express them with algebraic expressions", and delete "the connection and difference between factorization and algebraic expression multiplication".

3. Quadratic function: Addition transforms the expression of quadratic function of mathematical coefficient into the form of y=a(X-h)2+k(a≠0) by collocation method.

The expression of quadratic function can be determined according to known conditions; According to the formula to determine the vertex and symmetry axis of quadratic function image (formula does not need to be memorized and deduced) "has been deleted.

4. Quadrilateral: Delete the knowledge about trapezoid.

5. Circle: add the concepts of "equal circle" and "equal arc".

6. Similarity: "Similar polygons, similar triangles's judgment and nature, similar graphics" need to be understood.

Add "parallel lines are divided into segments in proportion, and simple practical problems are solved by similarity."

"Add" the basic properties of proportion, similar polygon and similar ratio, the judgment and properties of similar triangles, and the possibility of using potential to enlarge or reduce a graph ".

Grasp the basic fact: two straight lines are cut by a set of parallel lines, and the corresponding line segments are proportional.

Language: The proportion of classical Chinese has increased.

The Chinese content of the 20 15 senior high school entrance examination is still three parts: accumulation and application, reading and writing, but the specific test sites have changed slightly.

① Accumulation and application

Memorizing ancient poems added 3 pieces.

The "accumulation and application" part of the exam has increased and decreased, and the test sites are more specific: for example, "the order between sentences can be adjusted, and attention should be paid to coordination and cohesion; Pay attention to students' listening and speaking ability, such as test sites 7, 8 and 9 in the description; Pay more attention to the depth, breadth and speed of students' "thinking", such as 1 1, 12,13 in the description; Increase the "self-designed literary activity plan" and pay attention to the examination of students' comprehensive activity ability; The new test center guides students to pay attention to the society and the times, express their views and make suggestions; In the part of memorizing ancient poems, on the basis of the original 37 poems, three poems were added: Chapter II of Mencius, Preface to Sending Ma Sheng to Dongyang, and The First Meeting of Appreciating Lotte in Yangzhou.

Review guide:

For this part of knowledge, candidates should first be based on textbooks and be able to "refine in class".

When reviewing, we should pay attention to: the sound, shape and meaning of words should be closely around eight Chinese books, especially the notes after class and the reading, writing and writing after the book. The sound and shape of words that are easy to make mistakes and confusion should be memorized repeatedly.

For the dictation of ancient poems, candidates should recite the original text.

② Reading comprehension

Five new classical Chinese reading courses were added.

Reading classical Chinese: explain the purpose of emphasizing the inheritance and development of traditional culture and the actual needs of the senior high school entrance examination. Five new titles have been added to the appendix (the book thinking with Zhu Yuan, the biography of Mr. Wu Liu, the story of Ma Shuo, a nuclear ship and the Dragon Bell Team).

Candidates should pay attention to the accurate grasp of key substantive words and the dredge of literary meaning when reading classical Chinese.

Competent candidates can also review through sorting, deeply understand the ideological connotation of classical Chinese, and greatly improve the reading ability of classical Chinese.

Modern Chinese reading: A new point 12 has been added to the notes: "Reading a complicated and discontinuous text composed of various materials can help you understand the meaning of the text and draw meaningful conclusions". The examination center pays attention to the examination of students' thinking ability of "seeking common ground while reserving differences", and requires candidates to have the ability of "integrating, refining and summarizing" and the ability of meditation, exploration and exploration.

Review guide:

For the reading comprehension of modern texts, candidates should carry out speed reading training and in-depth training of independent thinking in unit time, choose famous books as the main reading training materials, and focus on solving the following problems: emphasizing overall perception, grasping the text as a whole, and having a complete understanding of the thoughts and feelings that the author wants to express; Emphasize the dialogue with the text, follow the text and gradually enter the author's spiritual world, to listen, touch, feel, chew and even cook the text; Pay attention to the comprehensiveness of thinking angle; Pay attention to the standardization of the answer statement.

English: The second volume of Grade 9 does not include the examination scope.

Compared with 20 14, the description of English senior high school entrance examination in Harbin has changed greatly. The scope of the examination was narrowed by one book, and five compositions were cancelled in written expression.

① Adjustment of test questions structure

1. Reduce the difficulty and cancel five sentences of composition.

In order to reduce the difficulty, the original reading expression (b) is combined with the written expression, and the score is 20 points; That is, the original five-sentence composition of the senior high school entrance examination is not independently examined, but is incorporated into the "big composition" for combined examination.

Judging from the examples given in the exam instructions, written expression reduces the difficulty.

This example examines practical writing. Judging from this style, it is closer to students' life, has timeliness, helps students solve daily practical problems, and can also properly examine students' comprehensive language use ability.

The design of this question will give students more free space, which is conducive to students' individualized use of English knowledge and skills for ideological exchange.

2. Adjust the original reading expression (a) to a task reading question as the fifth task, and the examination form remains unchanged.

3. The total score of multiple-choice questions remains unchanged, and two grammar questions become two phonetic questions.

② Adjustment of proposition scope

The scope of the examination will cover the first and second volumes of the sixth grade of all EEC junior high school textbooks in urban areas; The first and second volumes of the seventh grade; Compared with last year, the contents of textbooks used in the first volume of Grade 8, the second volume, the first volume of Grade 9 (new edition) and counties (districts) are the same, which reduces the examination scope of one book.

The exam instructions of 20 15 require candidates to master 1736 words, 277 phrases, 14 grammatical items, 10 functional concept items and 2 1 topic items.

Compared with last year, 222 words and 40 phrases were deleted and 60 words and 20 phrases were added.

③ score adjustment

The adjusted test structure and scores are: Volume 1: 20 points for single choice, cloze 10, 20 points for reading comprehension, and 50 points for Volume 1.

Volume 2: Communicative Application 15, Task-based Reading 15, Written Expression 20, Volume 2 ***50.

Chemistry: Fill in the blanks and cancel two questions.

There are two main types of chemistry questions: multiple-choice questions and non-multiple-choice questions. The multiple-choice question is 15, with ***30 points; Non-multiple choice questions contain 8 small questions, with ***40 points.

Compared with the senior high school entrance examination in 20 14, the total score of chemistry examination is 70, but the total number of fill-in-the-blank questions is reduced by 2, from the original 10 to 8, and the physical and chemical comprehensive questions and comprehension questions are cancelled.

This year's comprehensive physical and chemical questions are not separate questions, but may appear in a fill-in-the-blank question, while last year's comprehensive physical and chemical questions were separate questions, and the annual score was about 3 to 4 points.

This year's comprehension question will not be a separate question, but related knowledge points about environmental issues will also be interspersed with one question in a certain question type for examination.

Compared with the past, the scores of some fill-in-the-blank questions will change accordingly, and new questions will appear in combination with the materials in the questions.

Candidates should pay attention to "two notes" in reviewing;

First of all, we should pay attention to the examination of double bases.

The description requires that the test questions focus on the basic knowledge and skills of junior high school chemistry, and the knowledge coverage rate reaches over 85%. Give them due points in key knowledge, and create flexible questions and gradient questions.

Secondly, we should pay attention to comprehensive examination.

The proportion of easy questions, medium questions and difficult questions is 5: 3: 2.

In the explanation, it is required that each test question should have its source in the curriculum standard, teaching materials, test description and question bank, and the questions should be clear and rigorous, and there should be no off-topic, strange questions or complicated calculation questions. The design of test questions is from easy to difficult, and there are certain levels.

Physics: delete 24 "understanding" level requirements

In 20 15, the layered requirement of "understanding" is added to the "two-way detailed list" in the layered requirement of curriculum objectives for senior high school entrance examination in physics.

And "knowledge" is a knowledge goal that is higher than "understanding" but lower than "understanding".

At the same time, a large number of understanding level requirements have been deleted, 24 "understanding" level requirements have been added to the knowledge content ability level requirements, and 24 "understanding" level requirements have also been deleted.

These changes reveal that the knowledge level requirements of the 20 15 physics senior high school entrance examination questions are decreasing, while the knowledge and experience level requirements are increasing, which avoids the misunderstanding that students' usual training questions are cumbersome, eccentric or too difficult, and avoids mechanically copying the provisions, formulas and laws in textbooks, which is conducive to reducing students' heavy academic burden and improving the effectiveness of classroom teaching.

It has important guiding and leading significance for students to master basic scientific knowledge, acquire basic experimental skills, learn basic scientific methods, cultivate scientific inquiry spirit and initially form a scientific world outlook, which meets the requirements of quality education.

Candidates should pay attention to the classroom teaching and training of "double basics" and the application of physics knowledge in life.
