最近,我们家正在装修新房子，瓷砖铺好，接下来该美缝了，妈妈看着横七竖八的一条条缝，犯了难，缝一共有多长?该买多少材料啊?
Recently, our family is decorating a new house. The tiles are paved. Next, it's time for beautiful sewing. My mother looked at the horizontal and vertical seams and made difficulties. How long are the seams? How many materials should I buy?
爸爸说:"刘宏梁,你都四年级了,快帮妈妈想想办法，算算有多少米?"
Dad said, "Liu Hongliang, you are in grade four. Help your mother find a way to calculate how many meters there are?"
这能算出来吗?我一时摸不着头脑,心想妈妈都解决不了的问题,我怎么能解决?
Can this be calculated? I couldn't figure it out for a moment. I thought, how can I solve the problem that my mother can't solve?
"一条缝、一条缝的量，然后把长度加起来?"我试着提出方案。
"The amount of a seam, a seam, and then add up the length?" I tried to come up with a plan.
"不好，这样的方法太笨，根本无法实现，就算费了九牛二虎之力，也不一定能算得清楚。"爸爸否定了我的想法。
"No, this method is too stupid to realize. Even if it takes nine cattle and two tigers, it may not be clear." Dad denied my idea.
"你再想想，缝与瓷砖有什么关系?"爸爸提醒到。
"Think again, what does sewing have to do with ceramic tiles?" Dad reminded me.
我立即跑到厨房，仔细地观看，发现每条缝都是由两块瓷砖的边缘对接而成，这样，缝的长度不就是瓷砖周长的一半吗?如果我知道了每块瓷砖的周长和数量不就能算出缝长了吗?
I immediately ran to the kitchen and looked carefully. I found that each seam was formed by the butt joint of the edges of two ceramic tiles. In this way, the length of the seam is not half of the circumference of the ceramic tile? If I know the perimeter and quantity of each tile, can't I calculate the seam length?
我马上把我的想法告诉爸爸："只要量出每块瓷砖的长和宽，再数出瓷砖的数量，我就能算出来了。"
I immediately told my father my idea: "as long as I measure the length and width of each tile and count the number of tiles, I can calculate it."
爸爸点点头，说："这个想法很不错，可是你确定数瓷砖数量是一件很容易的事?"
Dad nodded and said, "it's a good idea, but it's easy for you to count the number of tiles?"
我看看满墙满地的瓷砖，无奈地摇摇头。正当我灰心失望的时候，我忽然想到，算瓷砖数量不是我上学期刚学过的吗?假如我知道铺瓷砖的面积不就能算出来吗?我顿时感觉柳岸花明又一村。
I looked at the tiles all over the wall and shook my head helplessly. Just when I was discouraged and disappointed, I suddenly thought, didn't I just learn to calculate the number of ceramic tiles last semester? If I know the area of tiles, can't I calculate it? I suddenly felt that Liuan Huaming was another village.
我赶紧跟爸爸说："快来给我一起量墙和地面长和宽，我算出总面积就能算出数量啦。"
I quickly told my father, "come and measure the length and width of the wall and ground together. I can calculate the quantity by calculating the total area."
"哈哈哈，你要的尺寸设计师早就帮我们量好了，到装修图纸上去找一找。"
"Hahaha, the size designer you want has already measured it for us. Go to the decoration drawings to find it."
果真，设计图上长宽高、瓷砖的规格都很清楚，我赶紧拿起纸笔，算面积、算数量、算周长，厨房、卫生间、阳台，不算不知道，一算吓一跳，足足有500米长。
Indeed, the length, width and height of the design drawing and the specifications of the ceramic tiles are very clear. I quickly picked up the paper and pen to calculate the area, quantity and perimeter. I don't know about the kitchen, bathroom and balcony. It's 500 meters long.
"妈妈的世界难题被我破解了!"我迫不及待的把这个消息告诉了妈妈。
"Mom's world problem has been solved by me!" I couldn't wait to tell my mother the news.
妈妈亲了亲我的额头，高兴地说："我的儿子真棒!"
My mother kissed my forehead and said happily, "my son is great!"
我的心里甭提有多高兴了。原来学数学这么有用，和我们的生活联系这么紧密，我一定要加倍努力地学好数学。
Not to mention how happy I am. It turns out that learning mathematics is so useful and closely related to our life. I must redouble my efforts to learn mathematics well.
