Today, Bian Xiao invited Liu Dongxu, a senior student who graduated from Hengshui and is currently studying in Tsinghua University, to share with you how to review and prepare for the exam efficiently in the face of the changes in the syllabus of the 20 17 college entrance examination!
How to break through the three subjects of materialization and biology
Physics article
The improvement of physical difficulty is a foregone conclusion.
There is a sentence in the latest syllabus of 20 17: "Further refine the examination requirements of understanding, reasoning, analysis and synthesis, applying mathematics to solve physical problems and experimental ability, and add examples."
Don't think this is nonsense, it's a euphemism for everyone: the topics we didn't want to see in the past, involving the summation of infinitesimal elements, experimental design, periodicity of magnetic field, all kinds of wonderful choices without discipline, and big problems with more complicated processes, will be fierce! In the future, the country is determined to get rid of the embarrassing situation of "comprehensive score =1/kloc-0+chemistry+biology-any random number between 0 and 5". But at the same time, there are a lot of examples in the latest syllabus, which become our valuable review resources.
Reading more examples, understanding examples and studying examples are important steps to return to textbooks and outlines. All the proposition principles of college entrance examination are "from textbooks, higher than textbooks", so we should pay more attention to textbooks when reviewing, so as to achieve the effect of one being ten.
Meanwhile, think more. Don't flinch from these so-called questions, just jump at the sight. In review, we will see, do and make mistakes in a large number of questions. Never skip the wrong question with a sentence "I won't take the exam anyway", but think more about why I think the question is difficult and why I am wrong. The difficulty of physics is that it is easy to make mistakes. We never lack the amount of practice (provided that we are not lazy), so it is more important to reflect and organize after practice. If you pay attention to reflection, you will soon realize that this question wants you to jump into that pit, then your thinking will not be wrong, and the rest, the details will determine success or failure.
Elective courses 3-5 are required, and elective courses 3-3 are required.
Adding momentum to the physics test paper will undoubtedly increase the difficulty of mechanics. But in the first class, we saw a lot of comprehensive problems of momentum and energy, so we just need to keep a normal mind while maintaining basic training (in the past, many required questions involved momentum just because its embarrassing position needed more explanation, but now it is more natural to transition). The momentum is not difficult, but careful analysis is the key. Of course, the degree of attention must come up! !
Elective course 3-3, Thermodynamics, made its debut, which was ignored because of its relative independence. However, his requirements for computing power are general, and many difficult concepts are not required in the college entrance examination. Just like when I was studying 3-4, I followed the teacher closely in class, and they wouldn't miss the key points! Among them, the most important thing is the nature of gas and its related transformation, but it is only a quantitative expression of a little knowledge we have come into contact with in chemistry class. As long as you keep a pious heart for physics, 3-3 is not afraid.
In short, the difficulty of physics has increased, but as long as we don't lazy to do problems, correct mistakes without discount, keep thinking and keep confidence, physics is still our dish!
Chemical articles
It's not important to delete elective course 3-2 ... It was really useless. Do you really dare to choose 3-2 in the completely blank college entrance examination room? Please tell me the percentage of China apatite in the world output! )
The beauty of chemistry (keng) and chemistry (die) lies in that there are many subdivided knowledge points, and there are many irregular numbers in the calculation part, which also requires certain experimental ability. Unlike physics, which requires a lot of practice and summary, chemistry mainly follows the teacher in class, plus patiently sorting out textbooks and other knowledge. Grasping the foundation is victory. For the calculation, everyone must not panic. Computing ability is omnipotent. Everyone who is dominated by a large number of mathematical and physical problems every day must have problems that cannot be calculated. Just be patient, patient, patient! Victory belongs to you!
Biological articles
Elective course 3 added PCR. Elective courses are generally concentrated on one textbook, and generally three books are selected. After the reform, the contents of "two choices one" and "three choices one" have been reduced, but the characteristics of "two choices one" mainly by memorization remain unchanged. Just take it somewhere else.
Choose 3 plus PCR, which is a difficult point to understand, and rote learning can't solve it. It is suggested to draw more pictures, summarize more and sort out the process in the notebook.
Biology is not difficult, and there won't be too many controversial points in the exam, so we should always turn over the textbooks and dig carefully. There is no harm in remembering more and memorizing more. Classroom is particularly important, so we should firmly grasp the mainstream and let the teacher's ideas correct you or ignore or entangle you. Our goal is to make creatures contribute the most points in the shortest time!
Examination skills of comprehensive science examination
The comprehensive test is probably the one that needs the test-taking skills most among the four courses in the college entrance examination. And the test-taking skills * * *.
About rhythm control
Personally, I prefer the "sequential flow" method, that is, to do it in the order of the test papers, because it can avoid being trapped when a subject is too difficult, and at the same time, I can accurately control the time every time (for example, it takes 38-42 minutes for me to do 2 1 0/0 minutes for the physics finale, and 10 minutes for the chemistry three major questions.
Setting the time node in this way is of great benefit-comprehensive management is a marathon, and setting the "punch point" can refine the goal and complete it step by step, which is more likely to reach the finish line smoothly. If you spend a lot more time than usual in this section (> 4 minutes), then I suggest skipping it directly (if it is a multiple-choice physics question, just choose an insurance one and get 3 points).
Some students will do multiple-choice questions for nearly 1 hour, and the final total score is often unsatisfactory. Because any standardized test depends on the total score obtained in a limited time, even if the final question is perfect and simple, it is still not an expert. After all, the questions 1 and 2 1 are equivalent to 6 points at the time of admission. Without any 6 points, it is possible to miss the ideal university, but the 6 points of 2 1 topic are even more difficult.
Grasp the rhythm of comprehensive management, that is, regardless of self-test or exam, we should give up decisively, don't be greedy for questions (that is, the wisdom of "overall awareness", that is, "willing to give up"), mark the skipped questions or questions that are not sure about the answers, and remind ourselves to do a complete test before making up the questions (focus on the answers after finishing). Sometimes you can use the time left after finishing to "save" the questions you skipped before, which will often make you suddenly enlightened.
About inspection
In my opinion, comprehensive management is also the most important test (the essence is to test the details). After practicing about 10 sets of papers, everyone will be able to spare 5- 10 minutes from the almost endless examination (some students even more). And the time of inspection is extremely important! ! ! The efficiency of grading even exceeds that of doing problems. I am generally "blank questions > multiple-choice exams > the foothold of big questions > chemical equations > chemical formula writing >: look at the overall situation." This list is my best test-taking skill. )
The first thing to check is to skip the unfinished questions or multiple-choice questions before. As for which one should be given priority, it depends on the specific situation and personal decision. I believe that every student has had an embarrassing situation like choosing B and D on the answer sheet, and the comprehensive multiple-choice question is especially wrong (6 points for one question! ) So it is necessary to check it again.
If the score of the empty question is not very high, let it be, and it is king to ensure that all the scores of the multiple-choice question with 126 are obtained. Then there is the "foothold of the big question", that is, pay attention to whether the foothold of your answer is required by the topic. For example, if the topic asks about the electric field intensity rather than the size of the electric field intensity, then your answer must be both the size and the direction; For example, the title requirement is ">" or "
In the last minute or two, browse the whole volume and immediately correct any obvious mistakes. For example, typos (such as the word "hammer" in spindle), such as CH3- 3 written as 2 in organic chemistry. All this work has been done, and I think non-technical mistakes can be avoided to the greatest extent. (Richard) The contest between masters is not how many points they can get, but who makes fewer mistakes. "Details determine success or failure. The college entrance examination is an examination for selecting talents. If these details are not refined, how can we choose you to take on a big job in the future? "
About brushing questions
Before you brush, you must know what your purpose is. Senior three's time is precious, and it is difficult to find out all the 2.5h hours, so we must not waste them. The function of heald winding is never used to practice the finale or a specific plate, it must be used to brush proficiency. (I will mention it later when I practice the finale).
I suggest adding another set to the regular Saturday afternoon grade exam (I usually do it by myself on Wednesday night, so that my hands will not be born after practicing once every three or four days), because I must be proficient in management exams, that is, I must be familiar with the style of test papers, grasp the rhythm, check skills and so on. More importantly, I will "dawdle"-during this 2.5h hours, I will exercise myself to concentrate on the examination paper in front of me.
More importantly, once you decide to do a whole set of sorting, you can't give up halfway (so let yourself feel at ease before making a set of papers), try to "imitate" the college entrance examination environment (for example, only allow yourself to use an 8-inch white draft paper), be strict with yourself, and never waste a second doing the questions until the last minute. I started to make my own test papers in advance from September of 15, and added one set every week, week after week (New Year's Day is the same) until the college entrance examination. Plus the school's, there should be 80 or 90 sets of papers made by myself.
Again, brushing sets of papers is the structure of practicing papers, and the improvement of core ability lies in the plate training of single subject (for example, I bought two or three sets of comprehensive papers to disassemble the plates for brushing physical finale, comprehensive multiple-choice questions, chemical experiment questions and chemical process questions, so as not to waste time).
About mentality
This point was also mentioned in the previous article. Comprehensive management (as well as other subjects) must not panic. Training so much at ordinary times also makes you really go to the examination room. If you lose this score, you lose. It's the same with someone else to fill it in. Comprehensive management is to "grab" 300 points in 2.5h hours, not to be petty, to take care of the overall situation and maximize the score. The above are some suggestions I want to say about the mentality of taking the exam.
It should be pointed out that you should never think that comprehensive management depends on these things. In the final analysis, the real improvement depends on the hard power of science and engineering students in three subjects. Only by reviewing these three subjects in a down-to-earth manner can we make great progress, otherwise it can only be "puffiness"
