今天晚上妈妈特别忙，又要打扫卫生又要折叠衣服。我大声地说：“我宣布：我要帮妈妈叠衣服了！”妈妈听了，高兴地说：“好，真是个好孩子。”说完，我就开始行动。
My mother is very busy this evening. She has to clean and fold her clothes. I said loudly, "I announced: I'm going to fold my mother's clothes!" Mom listened and said happily, "OK, what a good kid." With that, I began to act.
我拿起一块红领巾，红领巾是三角形的，该怎么折呢？我想了想：数学课上不是教过对称轴吗？我照这个做，一定没错。我先找到红领巾的对称轴，沿着中心线对折，变成了两层三角形。我把它其中的两个角向内折，折成了一个长方形，红领巾终于折好了。
I picked up a red scarf, the red scarf is triangular, how to fold it? I thought about it: didn't symmetry axis be taught in math class? I must be right to do it. First, I found the symmetry axis of the red scarf, folded it in half along the center line, and turned it into a two-layer triangle. I folded two of its corners inward into a rectangle, and finally the red scarf was folded.
我又拿起一件衣服，先把两只袖子往中间折，变成一个长方形，又把衣服的下摆往上折，成了一个小长方形。就这样，一件衣服又被我折好了。剩下的袜子就更简单了，我飞快地动起手来。
I picked up another dress, first folded the two sleeves in the middle, and turned it into a rectangle, then folded the hem of the dress up, and turned it into a small rectangle. In this way, a piece of clothes was folded by me. The rest of the socks are simpler, and I'm moving quickly.
不一会儿，我就全部折完了，妈妈看完我折的衣服，连声说：“真是个勤劳的好孩子！”
After a while, I finished folding all my clothes. My mother read my clothes and said, "what a hard-working boy!"
