"铅笔的使用技巧：如何延长其使用寿命"
Firstly, grasp the pencil correctly by placing it in the center of your palm and gently holding it with your thumb, index, and middle fingers. This can maintain stability and balance while writing, reducing writing errors caused by hand tremors. Secondly, apply moderate force during writing. Excessive force can accelerate the wear of the lead and affect the writing experience and service life of the pencil. Therefore, it is necessary to grasp the appropriate force to maintain smooth writing. Thirdly, regularly check if the tip of the pencil is sharp. If it becomes blunt, use a pencil sharpener to keep it sharp. This can improve writing quality and prolong the service life of the pencil. Fourthly, avoid frequently twirling the pencil while writing as this habit can accelerate the wear on its surface and affect both its appearance and writing experience. Lastly, properly store your pencils by avoiding placing them in damp or direct sunlight as this can cause the barrel to become damp or deformed. Additionally, avoid mixing pencils with other sharp objects to prevent the tip from being scratched.
