Matters needing attention and guide of Liaoning college entrance examination mathematics answer 1. The relationship between answering questions and time
Generally speaking, if you want to do well in the college entrance examination, you must have solid basic knowledge and a certain amount of practice, supplemented by some problem-solving methods and examination skills. In previous years, many candidates complained that the exam time was not enough, which led to the lack of time to do the questions they could do, and they felt "lacking".
The college entrance examination is about personal ability, which requires candidates not only to do questions, but also to answer them accurately and quickly. Only in this way can they finish within the specified time and get higher scores. Therefore, it is very necessary for most college entrance examination students to develop fast and accurate problem-solving habits and master problem-solving skills skillfully.
Second, the relationship between quickness and accuracy
The word "quasi" is particularly important in the current situation of large amount of questions and tight time. Only "accuracy" can score, and only "accuracy" can save you the time of examination, while "quickness" is the result of usual training, not a problem that can be solved in the examination room. If you are quick, you will only make mistakes in the end. For example, in last year's application problem No.21,it was not difficult to list piecewise analytic functions, but quite a few candidates miscalculated quadratic functions or even linear functions in a hurry. Although the following part of the problem-solving idea is correct and takes time to calculate, there is almost no score, which is inconsistent with the actual level of candidates. Slow down and be more accurate, and you can get a little more points; On the contrary, if you hurry up and make mistakes, you will not get points if you spend time.
Third, the relationship between examination and problem solving
Some candidates do not pay enough attention to the examination of questions, are eager to achieve success, and rush to write, so that they do not fully understand the conditions and requirements of questions. As for how to dig hidden conditions from the problem and stimulate the thinking of solving the problem, it is even more impossible to talk about it, so there are naturally many mistakes in solving the problem. Only by patiently and carefully examining the questions and accurately grasping the key words and quantity in the questions (such as "at least" and "a>0", the range of independent variables, etc. ), and get as much information as possible from it, so as to quickly find the direction to solve the problem.
Fourth, the relationship between "doing" and "scoring"
To turn your problem-solving strategy into a fractional point, it is mainly expressed in accurate and complete mathematical language, which is often ignored by some candidates. Therefore, there are a lot of "yes but no" and "yes but incomplete" situations on the test paper, and the candidates' own evaluation scores are far from the actual scores. For example, many people lost more than 1/3 points because of "jumping questions" in solid geometry argument, and "substituting proof with pictures" in algebraic argument scored poorly because it was not good at accurately transforming "graphic language" into "written language". Another example is the image transformation of trigonometric function in 17 last year. Many candidates are "confident" but not clear, and the points deducted are not a few points. Only by paying attention to the language expression of the problem-solving process can we grade the "can do" questions.
V. Relationship between Difficult Problems and Easy Questions
After you get the test paper, you should read the whole volume. Generally speaking, you should answer in the order from easy to difficult, from simple to complex. The order of examination questions in recent years is not entirely the order of difficulty. For example, it was more difficult to manage 19 than to manage 20 and 2 1 last year. Therefore, we should arrange the time reasonably when answering questions, and don't fight a "protracted war" on a stuck problem, which will take time and won't get points, and the questions we can do will also be delayed. In recent years, mathematics test questions have changed from "one question to many questions", so the answers to the questions have set clear "steps". Wide entrance, easy to start, but difficult to go deep and finally solve. Therefore, seemingly easy questions will also have the level of "biting hands", and seemingly difficult questions will also have points. Therefore, don't be timid when you see the "easy" questions in the exam and the "difficult" questions of new faces. Think calmly and analyze carefully, and you will definitely get the score you deserve.
