From pencils and erasers to backpacks and notebooks, these seemingly ordinary items play a crucial role in our learning process. However, the lifespan of these learning tools is often overlooked. Therefore, understanding and mastering the maintenance and care of learning tools is crucial for prolonging their lifespan, improving efficiency, and conserving resources. I. Pencils and Pencil Leads Pencils and pencil leads are one of the most commonly used tools in our learning process. To extend their lifespan, we can take the following measures: 1. Keep the tip clean and sharp to avoid becoming dull. 2. Do not leave unused pencils in damp or direct sunlight as this may cause the lead to break or fade. 3. Remember to cover the end of the pencil with a cap after use to prevent oxidation or dampness. II. Erasers Erasers are cleaning tools commonly used in our learning process. To extend their lifespan, we should note the following: 1. Avoid placing erasers in damp or high-temperature environments to prevent deformation or deterioration. 2. Do not store erasers with other hard objects to avoid scratches or compression on the surface of the eraser. 3. When using an eraser, gently rub to avoid excessive use that may cause cracks or changes in shape. III. Backpacks Backpacks are essential items for our school days, and their lifespan often affects our usage experience. To extend the lifespan of a backpack, we can take the following measures: 1. Regularly clean the backpack to avoid damage from stains and dust.

2. Avoid placing heavy objects or sharp objects in the backpack for an extended period to prevent wear or tears on the backpack.

3. Do not leave the backpack in damp or direct sunlight for long periods to prevent deformation or fading of color. IV. Notebooks Notebooks are important tools for recording knowledge and information. To extend their lifespan, we can do the following: 1. Avoid using notebooks in damp or high-temperature environments to prevent paper deformation or discoloration. 2. Do not scribble on the notebook randomly, keeping it clean and tidy. 3. Organize and categorize notebooks after use to avoid paper creasing or loss.
