A 300-word survey report and two small papers.
Middle school students are in adolescence with physical and mental development. They are enthusiastic, lively, curious and curious. In the process of learning, they are not satisfied with reading in class, but are eager to broaden their horizons and expand their knowledge from a wider range of channels to deepen their understanding of what they have learned in class. Extracurricular reading is the best way, a further extension and supplement of in-class reading, and plays a role in strengthening and promoting in-class reading. However, at present, the extracurricular reading situation of middle school students is not optimistic, and there are many shortcomings or misunderstandings, which need to be paid enough attention to. First, the analysis of extracurricular reading is relatively compact. In order to cope with the entrance examination, under the pressure of schools and parents, they turn around textbooks or teaching AIDS all day and drill into various homework, exercises or test papers all day. In fact, they spend little time reading after class. According to a survey, less than 1 5% can read extracurricular books every day, and less than 30% can read them for half an hour. Second, the deviation of extracurricular reading tendency If we exclude other factors and start from our own hobbies, then we will find that middle school students' reading interests are rich and diverse. Most of them like science fiction, prose, comics and fairy tales. But some students only pay attention to martial arts and romance novels. In particular, there is also a form of online romance novels, which fascinates people around. Boys prefer martial arts, while girls prefer Taiwan Province love novels and fashion magazines. Recently, some other books or "pocket books" have appeared in the book market. Their contents are vulgar and boring, even full of pornography and violence. Many students soon became addicted to reading, thinking it was the trend and fashion, leaving books in the school library and renting them outside. And many famous works at home and abroad, like Yesterday's Yellow Flower, are no longer very popular. For middle school students, these masterpieces seem to be very difficult, too difficult and not well understood. More students just regard reading famous books as homework assigned by teachers. Third, I didn't take good reading notes. A large number of middle school students have this experience. When arguing with others, you have to quote classics, but you have to dig your heart out, which is extremely embarrassing. This situation is widespread, mainly because I didn't make good reading notes. When they read, they don't use their brains or hands, and they are too lazy to write reading notes. They just read it, and then they don't know what to say. As the saying goes, a good memory is not as good as bad writing. Now 78% of middle school students can't do this, and they haven't mastered this correct reading method, just staying at a glance. Mathematics Paper 1 What is Mathematics? Some people say it's hazy fog, others say it's tangled thread. However, I think mathematics still has its so-called mystery. For example, our so-called equations and geometry all have their origins. Through the study of the chapter of comparison and proportion, I have benefited a lot. In the sense of 3. 1 ratio, I found that in fact, some things can't just look at the surface without paying attention to the actual connotation. Let's talk about shooting again. When I didn't learn to compete just now, I often made mistakes in the shooting percentage of athletes. Now that I have learned, I won't make any more mistakes on this issue. When watching the basketball game, I can help calculate the basketball player's shooting percentage and learn to use it. Every time my mother goes to the bank, she can also use book knowledge flexibly to help her calculate the bank's interest rate and deposit method. In the shopping mall, some clothes on the counter said they were on sale. I don't have to ask my aunt at the counter how much it costs anymore. Now I can calculate the discount price independently, and at the same time I have given myself a protection order to avoid the misjudgment of the shopping mall. Since I learned this, my life has been improved. I am no longer the little girl who only asks questions everywhere. Math helps me a lot. Although sometimes I am a little confused about mathematics, more often I feel happy and satisfied from it. At the same time, mathematics has become an indispensable course in my life. Now I want to learn more math knowledge and solve more oncoming problems! Example 2 of Math Paper 1: Things are unknown today, three, three, two, five, five, three, seven, seven, two, and the number of things is the least. To solve this problem, we can first calculate the data that meets all the conditions. Add it up again: the data that meets the condition of seven divided by seven divided by two is 3×5×2=30, the data that meets the condition of five divided by three is 3×7×3=63, and the data that meets the condition of three divided by two is 5×7×3=35. Finally add up: (30+63+35)-3× 5× 7 =. At this time, we find that * * * has two "3", two "5" and two "7" in the comprehensive formula, so it must be a common multiple of "3", "5" and "7", and multiply it by "2" and "3" at the same time to make the number meet three conditions. Because the minimum number is needed, the product of the multiplication of these three numbers should be subtracted. Example 2: There are thousands of people today, but divide by 2 1, divide by 5 2, divide by 7 3 and divide by 9 4. What's this number? ★ You can add several numbers that meet various conditions, and you can get the correct answer ★ This is an indefinite equation problem with 1, and the answer may not be unique [Solution] According to the prompt, we can calculate four numbers that meet the requirements in turn: the number that meets the condition of "remainder divided by 2 1" is 5× 7× 9 = 31. Please note that the number that meets the condition of "remainder divided by 7 3" must be multiplied by "2", "5", "7" and "9" mentioned in the title. For example, the number satisfying the condition of "remainder divided by 7" is 2. So we have to multiply 90 by other natural numbers until it meets the condition: 2× 5× 9× 6× 3 = 1620, and then we can get numbers that meet the other two conditions: 2× 7× 9× 2 = 252; The number satisfying the condition of "remainder divided by 9" is 2× 5× 7× 4× 4 = 1 120. Finally, don't forget to add up these figures: 315+1620+252+165438+. A: This number is 787 or 157. The above algorithm is actually based on the method in Sun Tzu's Art of War in ancient China, which is very ingenious and simple. We can also use this method to calculate this kind of problems in the future.
