In ancient times, there were highway expository readings.

Self-sufficient human bio-energy power generation ① With the depletion of coal, oil and other resources, the environment is deteriorating day by day. In order to develop new energy, some scientists have turned their research topics to the field of human bioenergy, and the use of human bioenergy to generate electricity has achieved initial results. There are some chemicals in the human body, which produce chemical energy when they react. For example, during metabolism, glucose reacts with oxygen molecules to release energy. With a little use, this energy can be converted into electric energy. According to this principle, scientists began to study human biological batteries. According to experts, the electrode of human biological battery is made of two carbon fibers with a length of 2 cm and a diameter of about 1/7000 nm. The outer layer of each carbon fiber is also coated with polymer, and glucose oxidase is used as a catalyst. The function of polymer is to connect carbon fiber and glucose oxidase into a circuit, and glucose oxidase is used to accelerate the chemical reaction between glucose and oxygen molecules. The working temperature of this kind of human biological battery is 37℃, and the pH value is 7.2, which is very close to the temperature and pH value of human blood. The energy it generates can drive a small sensor to monitor diabetes. ④ There are other forms of human biomass power generation. When a person is sitting or standing, it will constantly produce gravitational potential energy. At this time, if a special gravity converter can be used, this energy can be converted into electrical energy. An American company buried the power generation device in a crowded public place with a row of pedals outside. When pedestrians walk on the board, their weight presses on the board, making the rocker connected with the pedal move in the other direction, thus driving the central shaft to rotate and starting the generator connected with it. ⑤ In addition, the heat energy in human biological energy can also be utilized. People emit a lot of heat energy every day, and it is spread by radiation. Generally, an adult weighing 50 kilograms releases about 2500 kilocalories a day and night. A thermal battery made of human thermal energy can convert human thermal energy into electric energy. This kind of thermoelectric battery is so delicate that it can work as long as it is put in the pocket of clothes. It can play the role of power supply, supplying power to hearing AIDS, pocket TV sets, micro generators and so on. It can be described as self-generating and self-use. 6. Human energy can be said to be inexhaustible, and there is no pollution. We all have such amazing energy. Make full use of it to save energy for our society. I hope this new energy can benefit more and more people. (selected from The Mystery of Energy Science has been changed) 1. What kinds of power generation methods using human biological energy are introduced in the text? (3 points) _ Example 2. What is the scientific principle of developing human biological batteries? (3 points) _ _ Example 3. What is the function of adding the word "about" in the third paragraph of the selected text? (2 points) _ _ Example 4. What is the interpretation method used in the fourth paragraph of the selected text? What's the role? (3 points) Example 5. Please draw up a literary propaganda term from the perspective of "salvation". (4 points) 1, 1. [Answer] Using chemical energy to generate electricity; Utilize gravitational potential energy to generate electricity; Utilize thermal energy to generate electricity. [Analysis] This question examines the ability to extract important information from the text. These three sentences are also the central sentences of these three natural paragraphs respectively. 2. [Answer] There are some chemicals in the human body, and when they react, they will produce chemical energy. With a little use, this energy can be converted into electric energy. [Analysis] To solve this kind of problem, we must first analyze the stem, seize the key words, and find its paragraphs in the text. For example, the keyword "human biological battery" appears in the second paragraph of the selected text, so the required answer can be summarized from the sentence in the second paragraph. [Answer] The word "about" indicates the estimated value. The number is uncertain (the specific answer is better), which reflects the accuracy of the explanation language. [Analysis] This question examines the accuracy of the explanation language. As far as the situation introduced in this paper is concerned, the word "about" used to express the estimation can better reflect the accuracy of the explanation language, because this kind of carbon fiber is too thin to be measured accurately. 4. [Answer] Example; Specifically, gravitational potential energy can be converted into electrical energy by using a special gravity converter. [Analysis] Explain the method and its function, which is a common knowledge point in reading scientific and technological texts. Pay attention to the accuracy of noun terms. "Example" cannot be written as "column". 5. [Answer] For example, the slogan beside the faucet: Please don't make me cry! [Analysis] The slogan put forward must be the theme of "saving", such as saving water, electricity and solar terms, but also rich in literary talent, not too straightforward.
