Personal feeling
Multiple choice questions: 12457 are all given points, 3.6.8.9.10 If you look carefully, it is not a problem to get full marks.
Fill in the blanks: Everything is simple. Question 14 puts a reasoning problem in a difficult position. Problem 15 inequality Cauchy inequality can avoid choosing b or c.
Big problem: 16 is a trigonometric function of soy sauce, which is simple. 17 You have guessed the textbook example before the exam. You can ask the reduction to absurdity for the second time.
18 As long as you see the space vector, seconds kill is not a problem, it is very simple. Question 19 If you look closely, it should be almost the same.
Question 20 has a parabola. I didn't expect it, but it's not difficult. The second problem is the pure special point problem. First, set a nonexistent slope, find a special point, and then prove that it is constant (1, 0), and the amount of calculation is not large.
Question 2 1 is the most difficult, even if it is done here. Tangent zero inequality.
After the college entrance examination, many people are asking me, is the college entrance examination difficult this year?
On the afternoon of June 7, just after the exam, I went to the forum to post and see the students' various confidences. From all kinds of spit I have seen, my intuitive feeling is that this year's test questions in Shaanxi should not be simple.
After I got the real question for the first time, I scanned it roughly, and there was nothing strange in the whole paper. All the contents of this exam are reviewed by the teacher for the students. So many people are asking me how many points I got in the college entrance examination this year. This question is really difficult to answer and it doesn't make much sense. If you talk too much, you feel like you're bragging. If you talk too little, you don't look good. Touching my conscience, I said all the questions in the exam. As long as the foundation is solid and the real level is played, it is easy to get high marks.
Generally speaking, this year's college entrance examination in Shaanxi Province has the following characteristics:
1, infatuation does not change the gameplay, and all methods belong to the textbook.
20 10 Sichuan college entrance examination put forward a question to prove the sum and difference formula of trigonometric function. Inspired by the proposition group of Shaanxi college entrance examination, this question type is carried forward, and narrative is proved to be a special dish of candidates. 20 1 1 year, describes and proves the cosine theorem. Like a lightning bolt, it splits the examinee's eyes and tears off all their hair, saying that they can't play like this, but Shaanxi plays like this. 20 12, the appearance of the three perpendicular theorems surprised many students and teachers. Before the entrance examination of 20 13, many teachers and students guessed that the proposers in Shaanxi would be infatuated, so the trigonometric function passed, the solid geometry was finished, and then the probability, analytic geometry and derivative all came to the finale, and the only chance to prove the similarity fell in the section of sequence. In the last volume of the exam, Mr. Xin Daoheng narrated the arts and sciences respectively, and proved the summation formula of arithmetic progression and equidistant sequence. I smiled when I saw the same question on the real paper. It was infatuation. According to this logic, analytic geometry will be generated at 20 14! Formally, describe and prove the topic once a year; In essence, it is a return to the understanding of what mathematics is. Therefore, in the future, senior one students must pay attention to the teacher's explanation of basic theorem reasoning when studying. This is more valuable than solving problems with theorems. The review direction of senior two students is also very clear. Returning to textbooks and laying a solid foundation are the basic prerequisites for high marks.
2, given the conditions of hide-and-seek, she still hides half a face behind her guitar from us.
20 13 many topics in Shaanxi arts and sciences mathematics have this feature. If the known conditions are not generous enough, you always need to think twice. Just this once, cut off a group of miserable people. Some topics are small synthesis, involving many small knowledge points, much like the style of ten sets of questions before the new road exam. A small problem, such as 6.8. 10, is very painful for science candidates. The last question of this year's arts and sciences involves the inverse function and other major issues. An exponential function is given in the title, and the following knowledge points involve the tangent equation of its inverse function. When explaining exponential function and logarithmic function to students, I said that these two functions are very similar in many characteristics. Like a pair of brothers, we might as well call it a brother function. But many brothers finally turned against each other for various reasons, so professional mathematics called these two functions reciprocal functions. The knowledge of this topic is relatively simple, but it has not been tested in recent years. Some teachers talk about this topic directly, which leads to many children suddenly stunned when they see this topic. I can't dig out this known condition, and I can't feel it. This kind of small comprehensive problem is linked by one link, and any link will be hurt if it goes wrong. Therefore, we must have the ability to solve the mystery.
There is a great difference between liberal arts and mathematics, and boys and girls are divided into two worlds.
Compared with 20 12, there are eight small questions and two big questions in arts and sciences this year, while there are only three small questions in arts and sciences mathematics, and the difference between arts and sciences is more obvious.
Science mathematics needs to master more knowledge points than liberal arts, such as binomial theorem, permutation and combination, discrete random variables, definite integral, space vector and so on. Because it covers all aspects, there are many comprehensive problems in science and mathematics. Secondly, there may be fish escaping from the net every year. Last year, the topic of plane vector in science was basically gone, so when I discussed it with my classmates before the exam, I guessed that this year's vector would be combined with trigonometric function to form a big problem, and sure enough. This year, science mathematics is missing definite integral again. According to this logical relationship, candidates next year should be careful. Although definite integral is marginal knowledge in high school science mathematics, its lethality cannot be underestimated.
Compared with the 20 12 college entrance examination questions, the characteristics of this year's proposition are obviously more differentiated. This year's proposition style is particularly beneficial to children with good academic performance and solid foundation. Good grades this year are expected to get higher scores in mathematics. As a result, as soon as the results came out, everyone was 123, and everyone who had not passed the exam in peacetime tasted hundreds. When it comes to last year's Shaanxi college entrance examination mathematics, experts are in tears. The same thing happened in this year's Shaanxi College Entrance Examination. There is a statistical inference that gender variables have obvious correlation with English and math scores. Generally speaking, girls will be better at language subjects, such as English; Boys will be better at tools, such as math. In the one-to-one example, most girls make up math and more make up English. This year, according to a senior teacher, NMET English belongs to the happy type, and 130 is not a dream. For girls with good English, this is definitely the feeling of pouring cold water down. This further illustrates the short board effect, and it is necessary to improve the comprehensive strength, especially the weak links.
Year after year, the questions are similar and the years are different. In the past four years, the style of proposition has gradually formed and the level of proposition has become higher and higher. As long as the knowledge points are solid, the preparation is sufficient, the test results are good, and the ideal shines into reality. I hope Xin Daoheng will accompany you through this glorious time!
