I. General explanation
The examination paper closely follows the teaching materials and examination instructions, and starts with the familiar basic knowledge of the candidates, and examines the students' mathematical rational thinking ability and understanding of the essence of mathematics from multiple angles and levels. Based on the foundation, it is easy before it is difficult, with moderate difficulty, emphasizing application, being impartial and unfamiliar, and achieving the purpose of "testing the foundation, ability and quality". The knowledge content involved in the examination paper is within the scope of the examination syllabus, covering almost all the important contents of the knowledge learned in high school, which embodies the principle of "focusing on mastering key knowledge".
1. Return to the textbook and pay attention to the foundation.
The test paper follows the principle of taking basic knowledge as the main body, especially most of the knowledge points in the test instructions are involved. Among them, the application questions are based on the 70th anniversary of the victory of the Anti-Japanese War, and patriotism education is infiltrated into the test questions, so that students can feel the educational value of mathematics. The design of these problems has returned to the textbook and middle school teaching practice, which is very operational.
2. Set the difficulty and discrimination of the topic appropriately.
The 12, 16 and 2 1 of multiple-choice questions are comprehensive and difficult. Students should not only have strong ability to analyze and solve problems, but also have solid and profound basic mathematics skills, and also master the necessary mathematical ideas and methods, otherwise it will be difficult to complete them in a limited time.
3. Reasonable layout, comprehensive examination, focusing on mathematical methods and ideas.
In the multiple-choice questions, fill-in-the-blank questions, analytical questions and three-choice questions, the test paper repeatedly examines the key contents of high school mathematics. Including functions, trigonometric functions, series, solid geometry, probability statistics, analytic geometry, derivatives and other big problems. These questions are based on knowledge and ability, so that mathematical thinking methods and mathematical thinking methods run through the whole answering process.
The third chapter of biological composition: Tang Hejian's composition
After 2 1 year's research, Professor Guo, an expert from China Academy of Sciences, combined oat bran, mulberry leaves and onion cell walls by using bio-core techniques such as cell wall breaking-enzymolysis-chain breaking-molecular shearing, and cut out small molecular fragments with various physiological functions, resulting in new OS factors (OSins) which are beneficial to islet cell sensitization and cell repair and β -glucan which can be fully absorbed by human body. As a kind of green and pure natural special diet, it provides safer and more efficient dietotherapy intervention for people with diabetes and hypertension.
Cell wall of oat bran, mulberry leaf and onion
Natural hypoglycemic substance in oat bran-β -glucan
Oat (AnudeL), also known as naked oat, is one of the high-quality coarse cereals unique to alpine regions in China, mainly distributed in Shanxi, Hebei, Gansu and other places in Inner Mongolia. Shinohara flour, as a food for treating diabetes, has been widely spread among the people for a long time.
Oat bran: crude fat, crude protein, amino acids, dietary fiber, β-glucan and other major nutrients. The molecular structure and size of oat bran were changed by molecular shearing technology to extract high content of total β -glucan from oat bran.
The principle of mulberry leaves regulating blood sugar
The earliest Chinese medicine book Shennong Herbal Classic called mulberry leaves "immortal leaves". Chinese medicine has used mulberry leaves as Chinese medicine to treat "diabetes" (that is, diabetes in modern medicine) since ancient times.
The ancient Japanese book Drinking Tea for Health also records that mulberry leaves have the effect of improving "drinking water disease" (that is, diabetes in modern medicine). Research data at home and abroad confirm that the main hypoglycemic components in mulberry leaves are alkaloids and polysaccharides, which can improve glucose tolerance and prevent hyperglycemia and diabetes. It can promote insulin secretion, enhance insulin function and effectively regulate blood sugar.
The hypoglycemic principle of mulberry leaves is realized through two ways:
First, alkaloid DNJ( 1- deoxynojirimycin) inhibits disaccharide (sucrose and maltose) catabolic enzyme activity, thus inhibiting the absorption of disaccharide in small intestine and reducing the peak blood sugar after diet;
Secondly, the alkaloids cytisine and polysaccharide in mulberry leaves promote the secretion of insulin by β cells, and the polyhydroxy noranisodamine isolated from mulberry leaves has a strong inhibitory effect on glycosidase.
Quercetin in mulberry leaves can increase myocardial contractility and cardiac output, dilate coronary vessels and improve myocardial circulation.
Ф-aminobutyric acid, rutin and quercetin can lower blood pressure.
Ф-aminobutyric acid (GABA) is a neurotransmitter, which can promote the metabolism of brain tissue and restore the function of brain cells. At the same time, it can improve cerebral blood flow, enhance the activity of angiotensin converting enzyme ⅰ, and promote the decline of blood pressure.
Hypolipidemic and hypoglycemic effects of onion
Onion has the effects of warming middle warmer, regulating qi and promoting digestion. In Europe and America, onions are called "the queen of vegetables". There is an anti-blood sugar compound in onion, which is similar to the commonly used oral hypoglycemic drug "tolbutamide". It has a pungent smell, which can improve the level of insulin in blood, lower blood sugar and inhibit the increase of cholesterol caused by high-fat diet. Onion, the only known prostaglandin A, is a strong vasodilator, which can dilate blood vessels, reduce blood viscosity, increase coronary blood flow and reduce and prevent thrombosis. The lipid-lowering effect is more obvious than antonym, and it is better for patients with arteriosclerosis diabetes.
5 degrees sugar control means doing what you say.
Small molecular fragments obtained by molecular shearing and various OS factors with physiological functions can produce omni-directional, efficient and safe 5-degree sugar control in human body.
1, containing a large number of small molecular linear oligosaccharide fragments. It can intervene the metabolic function of human body disorder, so as to achieve the overall effect of dietary intervention on chronic diseases. These small molecular linear oligosaccharides are made by experts from Chinese Academy of Sciences using unique biological small molecule technologies such as wall breaking, enzymolysis, chain breaking and molecular shearing. These small oligosaccharide fragments directly regulate the gene expression relationship between DNA and RNA in cells. (This is the functional intervention of the product. Core components, core technologies)
2. This product contains various dietary fibers (soluble and insoluble) and β-glucan.
3. The product is also rich in mineral trace elements, such as potassium, calcium, iron, zinc, magnesium, manganese and selenium. And rich unsaturated fatty acids: linolenic acid and linoleic acid (softening blood vessels, preventing and treating cardiovascular and cerebrovascular diseases).
4. The products enter the intestine and produce a large number of short-chain fatty acids through secondary metabolism. Such as butyric acid, propionic acid, etc. Butyric acid can directly promote the differentiation and apoptosis of cancer cells, and has a good role in preventing tumors (dietary fiber anti-cancer video). Propionic acid can regulate the dysplasia of liver glycogen, which is beneficial to regulate blood sugar.
5. Control complications: blood pressure regulates OS factors and regulates blood pressure; Breaking dietary fiber can relieve constipation and detoxify, control weight, regulate triglycerides and prevent complications.
Effect of sugar on healthy functional diet
1, gastrointestinal tract: 1-3 days, 80% of people defecate more frequently, with a large amount, smelly and black, frequent exhaust times, smelly and so on (fast discharge, toxic accumulation). 1-3 days later, the stool of the sparse people gradually took shape. At the same time, about 10% people have symptoms similar to constipation. Less than 10% people have no obvious intestinal reaction. The above three kinds of intestines
Tao reaction shows different States because of its different intestinal metabolic functions. After 1-2 weeks, people who have these reactions gradually return to a new normal intestinal state, showing that the stool is tangible, soft and bright, and the stool is 1-2 times a day, smooth and fast. A few people reach normal state within 2-4 weeks. (Drink plenty of water when taking functional meals)
Stomach reaction: satiety, a few people have slight acid reflux, which can judge the function of the stomach. The viscous dietary fiber of this product has protective effect on gastric ulcer.
2, blood sugar. 1-3 months, and the effective rate is over 60%. A, delay gastric emptying, so that the sugar in the stomach slowly enters the intestine, which plays the role of peak clipping and valley filling. B, enter the intestine
The high-sugar, high-protein, high-fat and high-toxin parts of Dao are absorbed and excreted by this product (fast excretion). C, small molecular linear oligosaccharide fragments regulate and repair the gene expression relationship of islet β cells, and play a role in repairing islet β cells. D, regulating and repairing the gene expression relationship of insulin receptor cells: liver cells, fat cells and muscle cells through small molecular linear oligosaccharide fragments, and improving the sensitivity of insulin receptor. E, in the intestinal and hepatic circulation, this product forcibly takes away bile acid, which plays a role in regulating blood sugar. F, secondary metabolism forms short-chain fatty acid-propionic acid, which regulates liver glycogen heterogenesis. So as to achieve the function of regulating blood sugar. G, high potassium and low sodium, weight control, blood pressure control, cholesterol control and triglyceride control can all promote blood sugar metabolism (the importance of this role is clearly pointed out in the international diabetes guidelines).
3. Blood pressure: 1-3 months, and the effective rate is over 60%.
4. Blood lipid: 1-3 months, and the effective rate is over 65%.
5, weight loss, weight control: 1-3 months, abdominal fat decreased significantly (2 packs a day).
