There were three main ways for primary school students to look up words: 1. ** Pronunciation Sequence Search Method **: - [Usage: It is suitable for situations where you know the pronunciation but not the font.] - Method: First determine the sound order (the first letter of the syllable, must be capitalized) and syllable, find the sound order in the "Chinese Pinyin Syllable Index", then find the syllable, and find the word in the text according to the page number after the syllable. For example, if you wanted to look up the word "good" and knew that it was pronounced "hāo", you first had to determine the sound order "H". Then, in the "Hanyu Pinyin Syllable Index", you would find the page number corresponding to the syllable "hāo" below "H". Then, you would go to the page number in the main text to find the word "good". - [Note: You must read the pronunciation accurately, understand the initial and final of the word accurately, and master the writing of the letters.] 2. ** Division Leader Search Method **: - [Usage: It is suitable for situations where you know the shape of the word but not its pronunciation.] - Method: First determine the radical, count the number of strokes of the radical, find the page number of the radical in the "radical catalog", find the radical according to the page number in the "index table", count the number of strokes of the character except the radical, and find the character according to this, and search in the text according to the page number after the character. For example, to look up the word "tree", he first determined that the radical was "wood" and counted the number of strokes of the word "wood" to be four strokes. Then, he found the page number corresponding to the "wood" part in the "radical catalog", and then found the "wood" part in the "index table". Then, he counted the number of strokes of the word "tree" excluding the "wood" part, found the position of the word "tree" in the "index table", and finally searched in the text according to the page number behind it. - Deciding the rules of the division leader: - For words with a left-right structure, if both the left and right parts were the first division, the left side would usually be checked. - For characters with an upper and lower structure, if both the upper and lower parts were the division heads, they would usually be checked at the top. - For characters with internal and external structures, if both the internal and external parts were part of the head, the outer frame would usually be checked. - A character made up of two or more intersecting parts. The middle seat and the parts attached to the middle seat are both the first division. - On the frame of the word formation room were the words of "division" and "combination"."Division" and "combination" were the first parts of the word, and "combination" was the side of the word. - For characters that were arranged in the shape of "Tian", the head was usually at the corner of the character. Sometimes, the parts at several corners were all the heads. The head could be checked according to the order of writing. - In pictophonetic characters, sometimes both the side of the form and the side of the sound are the radical. Generally, the side of the form is checked. When there were more than one division leader in the same position, the general principle was to "check more, not less." 3. ** Counting strokes to check characters **: - [Usage: It is suitable for single-character characters and characters with unclear radical. All single-character characters can be used as the radical and searched by the radical searching method.] - Method: Count the total number of strokes of the character, find the corresponding page number of the character in the Index of Strokes of Difficult Characters, and find the character according to the page number in the text. For example, the word "concave" was a single-character character. The number of strokes counted was five strokes. In the "Index of Difficult to Search Character Strokes", find the page number corresponding to the five strokes, and then find the word "concave" in the text. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The table tennis racket grip was divided into the horizontal grip and the penhold grip: ** 1. Horizontal Grip Technique ** 1. ** Basic Grip Method ** - Open your palm naturally and don't hold the racket tightly. The middle finger, ring finger, and little finger naturally held the racket handle, and the edge of the racket was facing the tiger's mouth; the thumb was on the front of the racket, and gently stuck to the middle finger; the index finger naturally straightened and placed diagonally on the back of the racket. - When taking a natural shot, the front 2/3 of the palm was attached to the handle, and the back 1/3 could be empty or suspended, which was convenient for changing the shape of the racket when holding it. The side of the thumb was placed at the junction of the front handle and the board, the index finger was placed at the back of the board, and the position of the entire hand was at the middle front of the handle. 2. ** Adjusts in different hitting situations ** - [When serving: You can lean your hand forward a little and grab the board more with your fingers. This way, you can control the board more accurately and transfer your power.] - [When in a stalemate: Move your palm back a little, but not too far back. It's not easy to control the force accurately if you move too far back.] - When attacking the ball with the forehand, the thumb should move back slightly, and the index finger should move forward to support the back of the board to suppress the racket shape. - When attacking the ball with a backhand, the thumb needs to be pressed forward, and the index finger needs to be retracted from the back to press the board. 3. ** Avoiding wrong grip ** - It was best to avoid holding the handle with all your hands like holding a stick. This kind of grip could not control the power transmission and the placement of the board. - Don't hold the racket too tightly. That is, the index finger, thumb, and middle finger can almost grasp the surface of the racket or even half of it. Although it is stable, it is difficult to control the power transmission and the change of the shape of the racket. - It was not advisable to hold the racket shallowly, that is, to hold the root of the racket handle loosely. This would make it easy to throw the racket out, and the strength transmission was very demanding. The wrist and fingers were too flexible, and the strength was easy to dissipate. ** 2. Penhold Grip ** 1. ** Basic Grip Method ** - His thumb pressed against the surface of the board and at the same time, he leaned against the handle. His index finger naturally bent to circle the handle, and the three fingers behind naturally bent to overlap and stick to the back. The middle finger was mainly stuck to the back, and the other two fingers were close to the bottom of the middle finger. This way, the three points controlled the board, which could stabilize the board and flexibly change the board. 2. ** Adjusts in different hitting situations ** - ** When holding the racket with the forehand **: The thumb needs to press hard on the racket face to control the inclined surface of the plate. The index finger cannot be placed casually and needs to hook the racket handle. When pulling the ball with the forehand, pay attention to the rotation of the racket head at the moment of contact with the ball. The index finger must be stuck in a good position. - ** Backhand grip (push block)**: The thumb needs to be loosened, and at the same time, the surface of the racket is erected. The thumb presses the middle or back of the racket handle, and the index finger hooks the root of the racket handle. At the same time, the joint of the index finger presses the surface of the racket. The direction of the force is opposite to the direction of the thumb, giving the racket a forward force. - ** Backhand grip (penhold horizontal hit)**: The index finger should hook the handle and exert force. The thumb is only an auxiliary control plate type and does not exert force. The three fingers on the back can be fully opened to support the bottom plate, but they do not need to be completely straight. They can be half-bent. This way, when the backhand penhold horizontal hit, it is easy to make the racket surface rotate instantly and increase the instantaneous friction force against the ball. 3. ** Avoiding wrong grip ** - It was better to avoid using the fingers to hold the racket, which was too "flexible". Although this grip had an advantage when rubbing the ball and serving, it would be weak and the racket would shake when attacking the ball with both hands. - Don't hold the racket deeply. When you hold the racket deeply, the back three fingers are completely stretched out on the back. Other than the complete transmission of force when pulling the ball, the other movements will be very awkward, especially the backhand push block, which almost becomes a blind spot. - A grip that avoided problems with finger force, such as the grip commonly used by amateur fans with the thumb pressing on the board and the index finger sticking to the side or even the back of the racket, most of the balls could not be put into place with this grip.

If primary school students discover a mountain fire, they should immediately take the following measures: 1. ** To ensure your own safety **: Primary school students should quickly stay away from the mountain fire area and avoid getting close to the fire source because the mountain fire spreads quickly and is dangerous. 2. ** Don't put out the fire yourself **: The scale of the mountain fire is usually large. Primary school students don't have enough ability and experience to put out the fire. Don't try to put out the fire alone to avoid life-threatening situations. 3. ** Report in time **: Report the situation of the mountain fire to nearby adults (such as parents, teachers, local residents, etc.) as soon as possible, and inform them of the approximate location of the mountain fire and the size of the fire. If there are no adults around, you can call the local emergency number (such as the forest fire number, etc.) to call the police. 4. ** Follow instructions **: If firefighters or related rescue personnel arrive at the scene, follow their instructions, stay away from the danger zone, and do not interfere with the rescue work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
