**从小事做起：如何正确使用卷笔刀并保养学习用品** 一、正确使用卷笔刀

1. 准备阶段：首先，确保卷笔刀的刀片是干净且锋利的。如果刀片已经变钝，应及时更换新的刀片。 2. 安装铅笔：将铅笔插入卷笔刀的入口处，注意插入的深度，确保铅笔被夹紧但不至于太紧。 3. 开始削笔：轻轻旋转铅笔，让刀片均匀地削去铅笔的外层。切记不要用力过猛，以免刀片卡住或损坏。 4. 结束削笔：当铅笔削到合适的长度时，轻轻拔出铅笔，注意不要让木屑飞溅。 二、保养学习用品 1. 卷笔刀的保养：每次使用完卷笔刀后，应及时清理内部的木屑。可以用小刷子或吹气的方式清理。同时，定期检查刀片是否需要磨利或更换。 2. 铅笔的保养：铅笔使用后，应将铅笔头插回铅笔盒中，避免其滚动或被污染。如果铅笔头断了，可以用卷笔刀重新削尖。 3. 其他学习用品的保养：如书本、文具盒等，要定期清洁，避免受潮或弄脏。书本不要折叠或弯曲放置，保持平整。文具盒内要定期整理，确保各种文具的整洁和有序。 **How to Properly Use a Pencil Sharpener and Maintain Learning Supplies**

I. Proper Use of Pencil Sharpener

1. Preparation: Ensure that the blade of the pencil sharpener is clean and sharp. If the blade is dull, replace it with a new one promptly. 2. Inserting the Pencil: Insert the pencil into the entry of the sharpener, taking care of the depth to ensure that the pencil is held tightly but not too tightly. 3. Sharpening the Pencil: Rotate the pencil gently to allow the blade to evenly shave off the outer layer of the pencil. Remember not to apply too much force, as this may cause the blade to jam or become damaged. 4. End of Sharpening: When the pencil is sharpened to the desired length, gently pull out the pencil, taking care not to let wood shavings fly around.

II. Maintenance of Learning Supplies 1. Pencil Sharpener Maintenance: After each use, clean out the wood shavings inside the sharpener using a small brush or by blowing them out. Also, regularly check if the blade needs to be sharpened or replaced. 2. Pencil Care: After use, place the pencil back in its box to avoid rolling or contamination. If the tip breaks, use the pencil sharpener to resharpen it. 3. Maintenance of Other Learning Supplies: Such as books, pencil cases, etc., should be cleaned regularly to avoid dampness or dirtiness. Books should not be folded or bent, but kept flat. The contents of the pencil case should be organized regularly to ensure cleanliness and orderliness of various writing instruments.
