介绍身体器官的作文
《我的神奇身体器官》
嘿，大家好呀！今天我来给你们讲讲我身体里那些超有意思的器官。
先来说说我的眼睛吧。
我的眼睛那可是相当厉害的，就说有一次我在街上走，老远就看到一个卖冰淇淋的小车，那花花绿绿的冰淇淋一下子就吸引住了我，我眼睛直勾勾地盯着，然后就不由自主地走过去了，哈哈，没办法，谁让眼睛这么敏锐呢，一下子就发现了好吃的。
还有我的耳朵呢，有一回我正在房间里写作业，突然听到外面传来很细微的“喵喵”声，我心里想：这不会是有小猫咪吧？我赶紧竖起耳朵仔细听，真的是小猫咪的声音呢，然后我就顺着声音找过去，果然看到一只超可爱的小猫咪在角落里。
再讲讲我的嘴巴呀，这嘴巴可太能说了，有一次和朋友们聊天，我那是滔滔不绝，从白天说到黑夜，把朋友们都逗得哈哈大笑，他们都说我这嘴巴呀，就像机关枪似的，停不下来。
我的鼻子也很厉害哦，有次我路过一家面包店，那香喷喷的味道一下子就钻进了我的鼻子，哎呀呀，我顺着那味道就走进去了，然后买了好多好吃的面包。
最后说说我的手吧，有一次我看到一个魔方，就想挑战一下自己能不能把它还原，然后我的手就开始不停地摆弄，嘿，还真让我给还原成功了呢！
这就是我身体里这些有趣又神奇的器官呀，它们每天都陪着我，让我的生活变得丰富多彩呢！希望它们能一直这么厉害下去，哈哈！。

那么你知道一篇好的作文该怎么写吗？以下是精心的三年级我发现了什么的秘密作文（精选4篇），希望能够帮助到大家。
我发现了星期五的秘密，每一个星期五，我去补习班的路上总是堵车。
我一直以为星期五晚上六点半就不会堵车了，但美好的想法总是被现实击碎。
有一次，我推迟到六点半上课，所以出门晚了点，结果一路堵到底！真烦！害得我都迟到了。
我在教室里可以看到马路上的各种情况，马路上的车子密密麻麻，就像成千上万只小蚂蚁似的，一辆辆仿佛都挨在一起了，如果你不仔细看，休想看到马路和地面。
有时在拐弯的时候，车子就像一条正在蠕动的毛毛虫，“毛毛虫”有时会少几个节，有时又会多几个节。
有一回也是星期五，我和爸爸妈妈自己开车去旅行，本来前面好好的，可是不一会儿我们上高速了，同时也堵起了车。
一直到吃晚餐的时候，我们还没有下高速，一家人的肚子早已空空如也。
下一次，我一定要带点粮食再出来。
鸡吃石子，也许我们经常见到。
可是它为什么要吃石子呢？这个秘密终于被我发现了。
有一天，我和表弟在院子里玩又见到公鸡东啄西挖，居然津津有味地吃起石粒来真奇怪。
对于鸡来说，稻谷和麦粒等，算得上是山珍海味了为什么还要吃石子呢？这个问题表弟也不明白。
爸爸告诉我，鸡的胃是很巩固的.，而胃的内部那么是一层黄色的皱皮鸡没有牙齿．我问爸爸：“那大一点的食物鸡怎么吃呢？”爸爸又说：“自己找鸡吃石粒的原因吧。
”“表姐我们还是查一查《十万个为什么》吧！”表弟在一旁说。
“好主意”。
我们翻开《十万个为什么》。
问题终于解决了。
原来，鸡和别的鸟不一样它没有牙齿，必须借助石子来磨碎胃里的食物。
石子就起到了这样的消化食物的作用。
石子在鸡胃的挪动下与食物挤啊，磨啊。
最后变成了浆糊。

介绍我的身体英文作文三年级上册全文共6篇示例，供读者参考篇1My Amazing Body!Hi everyone! Today I want to tell you all about my amazing body. Our bodies are so cool and can do so many incredible things. I hope you'll have fun learning about my body along with me!Let's start at the top with my head. My head is where my brain is located. My brain is like a super computer that controls everything I do. It lets me think, learn, remember things, and makes decisions. My brain gets messages from the rest of my body through my nerves. The nerves are like little messengers that carry information back and forth.On my head, I also have my face with my eyes, nose, mouth, and ears. My eyes let me see all the colors, shapes, and movements around me. My nose lets me smell delicious treats like freshly baked cookies or beautiful flowers. With my mouth, I can speak, eat yummy food, and smile big. And my ears let mehear all the sounds, like my favorite music or my friends laughing and playing.Under my head is my neck, which connects to my body trunk. My neck lets me move my head around and look in different directions. My body trunk has my chest, tummy, and back areas. Inside my trunk is where many of my vital organs are found that keep me alive and healthy.In my chest area, I have my heart, which is a very hardworking muscle. My heart beats around 100,000 times per day, pumping blood all throughout my body. The blood provides oxygen and nutrients to every tiny part of me. I also have lungs in my chest that allow me to breathe in air and get that oxygen for my blood.In my tummy area, I have my stomach and intestines where I digest the food I eat. The food gets broken down so my body can absorb the vitamins, minerals, proteins, and other nutrients it needs for energy and growth. I even have a liver that helps filter out toxins to keep my body clean on the inside.Attached to my body trunk are my two arms with hands, and my two legs with feet. My arms and legs let me move around, play sports, dance, write, draw pictures, and do so many fun activities. My hands have fingers that can grab, grip, and pickthings up. My legs have feet with toes that let me walk, run, jump, and skip. My bones give my body structure and let me stand up straight and tall.I have over 200 bones in my body that are all connected together with joints. My bones are covered with muscles that let me bend and move in all directions. My muscles are very strong but can also get stronger if I exercise and take good care of my body.Under my skin on the outside of my body, there is super cool stuff on the inside that keeps me alive and healthy. I have a heart that beats, lungs that breathe, a brain that thinks, a stomach that digests, and so much more. Our bodies really are incredible, amazing machines!I'm so thankful for my healthy body that lets me learn, play, explore the world around me, and live life to the fullest. Even though everyone's body is a little different, we're all wonderfully made. I hope you learned some new things about your awesome body today too! Let's give our bodies a big thank you for everything they do for us.篇2My Amazing Body!Hi, my name is Sam and I'm going to tell you all about the incredible body that I live in! Our bodies are so amazing and do so many cool things. Let me start by telling you about the parts on the outside that you can see.The HeadAt the top is my head, which holds my amazing brain to help me think and learn. My brain is kind of like a computer that controls everything I do. At the front of my head is my face with my eyes to see, my nose to smell, my mouth to eat and talk, and my ears to hear. I use my eyes to read books, watch TV, and play games. My nose lets me smell wonderful things like freshly baked cookies or beautiful flowers. With my mouth I can eat yummy foods like pizza and ice cream, and I can talk to my family and friends. My ears let me listen to music, birds singing, and what my teacher says in class.Arms and HandsConnected to my head are my arms which end in my hands and fingers. I use my arms to hug my parents, play catch, climb trees, and so much more. My hands are very useful to write, draw pictures, brush my teeth, and pick things up. My fingers help me type on a computer, button my shirt, and are great for pointing at things.Legs and FeetBelow my belly is where my legs start, all the way down to my feet and toes. My legs are very strong and let me run, jump, kick a ball, and dance. My feet are at the bottom and allow me to walk, skip, and hop around. My toes help me keep my balance and grip the ground. I'm very thankful for my legs and feet to get me places!Now I'll tell you about some important parts inside my body that you can't see.The HeartIn the middle of my chest is my heart. It beats lub-dub,lub-dub all day and night to pump blood all around my body. The blood carries oxygen and nutrients to give my body energy to breathe, move, and grow. My heart is a little bigger than my fist and works very hard for me. I should take good care of it by exercising and eating healthy foods.The LungsAnother big part inside me are my lungs. They are kind of like balloons that fill up with air when I breathe in, and deflate when I breathe out. The lungs take that air and put oxygen into my blood, and take out the bad carbon dioxide. Isn't that cool?My lungs keep me alive by getting oxygen to the rest of my body.I should try not to smoke or breathe polluted air so my lungs stay healthy.The StomachAfter I eat foods like sandwiches, fruit, or a big plate of spaghetti, it all goes into my stomach to get digested. My stomach is kind of like a blender that mashes up and dissolves all the food. Then it sends the good nutrients to my intestines to go into my blood and feed my body. But it gets rid of the waste that my body doesn't need. I have to be sure to eat good foods with fruits, vegetables, and protein to keep my stomach happy.The Bones and MusclesFinally, I can't forget about my bones and muscles! I have lots of bones all over my body that make up my skeleton and give me structure and strength. That way I don't just flop around like a blob of jelly! My muscles are connected to the bones and are kind of like stretchy rubber bands. When my muscles pull, it allows me to bend my arms, walk with my legs, chew with my mouth, and pretty much move anywhere. By exercising and eating right, I can build strong bones and big muscles.Well, that's an introduction to my amazing body and some of the most important parts that make me able to live, move, and grow. I have an incredible body that does so many things for me every single day without me even thinking about it. I need to be sure to take care of it by eating nutritious foods, exercising, getting enough sleep, and making healthy choices. Our bodies are the coolest things ever!篇3My Amazing BodyHi everyone! Today I want to tell you all about the amazing body that I live in. Our bodies are so cool and can do so many incredible things. Let me start by introducing you to the outside of my body.My skin covers my entire body and protects me. It's kind of like a cozy blanket that keeps my insides safe. My skin feels pretty soft, except for some rough spots on my feet and elbows. I have tiny hairs all over that help keep me warm. Under my skin, I have muscles that let me run, jump, dance, and move. My muscles are kind of stretchy and squishy.I have a head at the top with a face. My face has eyes for seeing, a nose for smelling, ears for hearing, and a mouth foreating and talking. I use my eyes to see colors, shapes, and the amazing world around me. My nose lets me smell delicious foods like chocolate chip cookies fresh from the oven. With my ears, I can hear birds singing, people laughing, and music playing.My mouth has teeth for chewing food and a tongue for tasting. I love tasting sweet treats and Mom's yummy home cooking. I also use my mouth to talk, tell jokes, and read out loud. At the top of my head, I have hair growing. My hair can be all different styles like braids, ponytails, or just hanging loose.My body has two arms with hands at the end. I use my arms to reach, throw, hug, and do so many things. My hands have fingers and a thumb that let me grab, hold, write, type, and more.I also have two legs with feet at the end for standing, walking, running, and jumping. My feet have toes that help me balance and grip the ground.Now let me tell you about what's inside my body. It's pretty amazing in there! My brain is at the top, protected by my skull. My brain is like a super computer that lets me think, learn, remember, and solve problems. Everything I see, hear, smell, and experience gets sent to my brain.My heart is a very important muscle that pumps blood all through my body. I can feel it beating in my chest. The blood travels through tubes called arteries and veins, kind of like the roads that cars drive on. My blood keeps all my organs healthy by giving them air and nutrients.Inside my body, I have other cool organs too like my lungs for breathing air, a stomach for digesting food, kidneys and a bladder for making urine, and intestines that help digest my food.I even have a spine running down my back that connects to my brain and lets me bend and move.Bodies are just so fascinating! We are like little worlds with cities (organs) and transportation systems (blood vessels) all connected and working together. Our bodies do an incredible number of things every second without us even thinking about it. We can see, hear, smell, taste, move, and so much more - all thanks to our amazing bodies.I'm so grateful for my body and all the awesome things it can do. I try to take great care of it by eating healthy foods, exercising, getting enough sleep, and staying safe. Our bodies are pretty much miraculous when you think about it. Aren't you glad you have one?That's my introduction to these incredible bodies we live in. Maybe you learned some new things or maybe it reminded you how marvelous our bodies truly are. Just think, while you were reading this, your brain was processing the words, your heart was pumping, your lungs were breathing, and so much more - all without you doing anything! How cool is that? Our bodies are hard at work 24/7, no days off. Let's be sure to appreciate them!篇4My Amazing BodyHi there! My name is Jamie and I'm going to tell you all about my awesome body. Our bodies are so cool and they can do so many amazing things. I'm going to describe the different parts and what they do for us. Get ready to learn some fun facts!Let's start at the top with the head. The head is kind of like the control center of the body. It's where we have our brain which is super important. The brain is like a computer that controls everything we do. It helps us think, learn, remember things, and even controls when we blink our eyes or breathe. The brain is protected by the skull which is really hard bone. I'm glad the skull keeps my brain safe!Our head also has the face with the eyes, nose, mouth, and ears. The eyes are probably my favorite part because they let me see all the colors, shapes, and cool things around me. The nose lets me smell delicious foods, flowers, and other scents. The mouth has our tongue and teeth for chewing food and talking. And the ears let us hear sounds, music, and when people are talking to us.Below the head is the neck which connects to the body trunk. The trunk has the chest area where we find the heart and lungs. The heart is a muscle that pumps blood all throughout the body. The blood carries oxygen and nutrients that all our cells need. The lungs are kind of like bellows that bring air in and out of our body. The lungs take that air and put oxygen into our blood.My trunk also has the belly area with the stomach and intestines. The stomach is a stretchy sac that holds the food we eat and starts breaking it down with stomach acids. Then the intestines continue digesting the food so we can absorb nutrients and get energy. The belly button is a cool reminder of when we were tiny babies growing inside our moms!The trunk connects to the upper and lower limbs. The upper limbs are the arms with shoulders, elbows, wrists, and hands. We use our arms and hands to do so many things - throw a ball,open doors, pet animals, clap, wave hello, and tons more. The hands have fingers and an opposable thumb which helps us grip and grab objects. I'm really grateful for my hands!Then we have the lower limbs which are the legs with hips, knees, ankles, and feet. Our leg muscles are super strong for running, jumping, kicking, and getting around. The feet have toes and arches which help us balance and walk upright instead of on all fours. Our toes grip the ground and the arches act like little springs as we step. Pretty neat!Did you know our body is covered with skin from head to toe? The skin protects the inside of our body from germs and stuff. It also has nerves that let us feel warmth, cold, pain, and other sensations. Plus the skin has sweat glands to help cool us down when we're hot. Under the skin we have bones, muscles, blood vessels, and other cool parts working together as a team.There are so many other fascinating parts of the body like the liver, kidneys, immune system, reproductive system, and more. But I think you get the idea of how amazing our bodies truly are. We're like living machines with all these parts doing important jobs to keep us alive and healthy. I'm going to take great care of my body by eating good foods, exercising, and treating it with respect. Our bodies are pretty awesome!篇5My Amazing BodyHi there! I'm going to tell you all about my awesome body today. Our bodies are really cool and let us do so many amazing things. I hope you'll learn some new stuff!Let's start at the top with my head.

After I chew up food in my mouth, it goes down my throat and into my stomach to keep digesting. My stomach and intestines are part of my digestive system that breaks down food so my body can use it as energy and nutrients.I have two arms with hands at the end. My arms and hands let me do so many cool things like writing, throwing a baseball, petting my dog, or giving someone a hug. I have muscles andbones in my arms that make them strong and let me move them around.My legs are pretty important too! They let me walk, run, jump, dance, and skip around wherever I want to go.

身体的秘密半命题作文
身体的秘密半命题作文从小到大，我一直觉得自己的身体里藏着许多秘密。
而在这些秘密中，最让我又爱又恨的，莫过于我那敏感又任性的肠胃。
说起我这肠胃啊，那可真是有一箩筐的故事。
小时候，我就特别贪吃，什么糖果、薯片、冰淇淋，只要是能放进嘴里的，我都来者不拒。
记得有一次过年，家里买了好多好吃的，有巧克力、瓜子、花生，还有各种水果。
我就像掉进了美食的天堂，嘴巴一刻也没停。
先是吃了好几块巧克力，那香甜丝滑的口感让我欲罢不能。
接着又抓了一把瓜子，嗑得那叫一个欢快，瓜子仁的香味在嘴里弥漫开来。
然后又看到了红彤彤的苹果，咬上一口，清脆多汁，别提多满足了。
可没过多久，我的肠胃就开始抗议了。
肚子里一阵翻江倒海，咕噜咕噜地响个不停。
紧接着，一阵剧痛袭来，疼得我直冒冷汗。
我捂着肚子，在床上滚来滚去，嘴里不停地哼哼着：“哎呀，疼死我了，我的肚子要炸了！”爸妈看到我这样，着急得不行，赶紧带我去了医院。
医生一番检查后，严肃地说：“这孩子吃太多乱七八糟的东西了，肠胃消化不了，以后可不能这么贪吃了！”我可怜巴巴地点点头，心里暗暗发誓，以后一定要管住自己的嘴。
然而，誓言总是很容易被打破。
随着年龄的增长，我的胃口越来越好，对美食的热爱更是有增无减。
上了中学后，学校门口有各种各样的小吃摊，什么烤串、麻辣烫、煎饼果子，每天放学都散发着诱人的香气。
我总是忍不住去买上一份，边走边吃。
有一次，我看到一家新开的烤串店，生意特别火爆。
那一串串烤得滋滋冒油的羊肉串，散发着迷人的孜然香味，一下子就把我的魂勾走了。
我毫不犹豫地买了十串，大口大口地吃了起来。
那味道，真是绝了，外焦里嫩，香辣可口。
我吃得正香，突然感觉肚子一阵不舒服。
一开始我还没在意，以为只是吃太快了。
可是没过多久，那种熟悉的疼痛又回来了。
我赶紧跑回家里，冲进厕所，一待就是半个多小时。
从那以后，我每次经过那家烤串店，心里都痒痒的，但又不敢轻易去尝试，生怕我的肠胃再次“发脾气”。
后来上了大学，离开了家，我的饮食变得更加不规律了。
人体的奥秘作文500字
人体的奥秘作文500字英文回答：The human body is a fascinating and complex system that is filled with mysteries waiting to be unraveled. From the intricate workings of our organs to the way our cells communicate, there is no shortage of wonders to explore.One of the most intriguing aspects of the human body is its ability to heal itself. When we get a cut or a scrape, our body immediately goes into action to repair the damage. White blood cells rush to the site of the injury to fightoff any potential infections, while platelets form a clotto stop the bleeding. Over time, new skin cells are produced to replace the damaged ones, and before we know it, the wound has healed.Another mystery lies within our brain. It isresponsible for our thoughts, emotions, and actions, yet we still have much to learn about how it all works. Scientistshave discovered that the brain is made up of billions of neurons, which communicate with each other throughelectrical and chemical signals. This intricate network allows us to think, learn, and remember. However, there are still many unanswered questions about the brain, such as how memories are formed and how emotions are processed.The human body is also incredibly adaptable. It can adjust to different environments and conditions to ensure our survival. For example, when we exercise, our muscles adapt by becoming stronger and more efficient. Our lungs and heart also adapt to provide us with the oxygen and energy we need. Similarly, when we are exposed to extreme temperatures, our body adjusts by either sweating or shivering to maintain a stable internal temperature.In addition to its physical abilities, the human body is also capable of experiencing a wide range of emotions. From happiness and love to sadness and anger, our emotions play a significant role in our daily lives. They can influence our decisions, relationships, and overall well-being. However, the exact mechanisms behind emotions arestill not fully understood. Scientists have made progressin understanding the brain chemistry and neural pathways involved, but there is still much more to uncover.中文回答：人体是一个充满奥秘的复杂系统，里面有许多等待揭开谜团的奇迹。

有关介绍人体器官的作文
《奇妙的人体器官》
嘿，咱今儿就来讲讲咱这身体里神奇的人体器官。
就说说咱这眼睛吧，那可真是个奇妙的玩意儿。
记得有一次，我和朋友们出去玩耍。
我们来到一个花园，哇，那五颜六色的花儿开得正艳呢！我就睁大眼睛拼命去看，想把这美丽的一切都尽收眼底。
我看到红的像火，粉的像霞，白的像雪，各种各样的颜色一股脑地钻进我的眼睛里。
我仔细盯着一朵花，看着它花瓣的纹理，那么清晰，那么细腻，好像是大自然精心雕刻出来的一样。
我还看到花瓣上挂着的小水珠，在阳光的照耀下闪闪发光，就像一颗颗小钻石呢。
我这眼睛啊，就像个小相机，把这一切都“咔嚓”拍下来存在我的脑海里了。
这眼睛让我看到了世界的美好和奇妙，它能让我看到远方的风景，也能让我看清近处的微小细节。
我们可得好好保护这宝贝器官呀，不然要是看不到这么美丽的世界了，那该多可惜啊！咱身体里的这些器官啊，真是各有各的本事，各有各的奇妙之处，值得我们好好珍惜和善待呢！
咋样，我讲得还不错吧，这就是我对人体器官的一点小感受，哈哈！。
健康的秘密_初一作文
健康的秘密大家好，我是胖国王，欢迎大家走进我的故事。
我很胖，走起路来很费劲，连绑鞋带都绑不上，因为我太胖了弯不下去腰。
有时候，我在开大会的时候话讲到一半就累得睡着了。
我不喜欢做运动，天天喜欢吃一些奶油、蛋糕、糖之类的食品。
我的身体很不好，每天都请医生来，医生说：“国王的身体不健康，这样下去可不行！”大家也都说我太胖了。
我很想瘦下来，可是，我又不知道该怎么办？我请大家想办法。
厨师让我少吃奶油、薯条、汉堡、冰淇淋之类的食物，多吃有营养的饭菜、肉、水果等食物。
医生建议我三餐之间不要吃零食，而且要常常做运动，比如：跑步、游泳、打球、做体操等。
公主让建议我一边玩呼啦圈，一边听音乐。
皇后给我想了一个绝妙的办法：把我的床搬到很高的地方，每天让我爬楼梯锻炼身体，这样我就能瘦下来了。
我照着大家说的办法做了几天，有点忍受不了了。
厨师就鼓励我，给我讲笑话，为我加油。
又过了几天，我又忍受不了了，厨师和医生一起鼓励我，给我唱歌，为我加油。
又过了好多天，我真的忍受不了了，大家一起给我演戏，为我加油。
又过了好多天，你们猜，我变成什么样子了？哈哈，告诉你们一个好消息，我终于瘦下来了。
从此以后，大家都说我是一个健康的国王。
小朋友们，你们知道我刚开始为什么这么胖吗？因为我特别贪吃，光喜欢吃奶油、糖之类的甜食，还不爱做运动，所以，我才变得这么胖，走路费劲，不能绑鞋带，做什么事情都不方便。
你们知道最后我为什么变瘦了吗？因为我三餐之间不再吃零食了，也不吃那些容易长胖的食物了，比如：巧克力、冰淇淋、汉堡等，而且我每天吃完饭都出去做运动。
所以，我才能瘦下来，我太开心了！以后，我就可以自己绑鞋带了，走路再也不费劲了。
小朋友们，你们想做一个健康的孩子吗？我想偷偷地告诉你们：每天的三餐要多吃一点，要多吃蔬菜、水果、肉、蛋等有营养的食物，少吃薯条、巧克力、冰淇淋、汉堡等容易让你变胖的食物，三餐之间不要乱吃零食，而且，最重要的是，每天都要做运动。
只要你天天这样坚持，你一定会成为一个健康的孩子！。

我的小秘密三年级作文（精选68篇）
我的小秘密三年级作文（精选68篇）我的小秘密三年级作文篇1屋后是一个小花园，那是我每天嬉戏玩耍的乐园。
秋天来了，金黄色的树叶洒落地面，踩上去沙沙作响，惬意无比。
我喜欢来这里，闻闻花香，听听鸟鸣，感受秋的气息。
特别是那棵老槐树，抬头仰望，上面满是鸟巢。
老槐树比我爷爷的年龄还大，褐色的树皮显示岁月的沧桑，小小的树洞是我快乐的秘密。
树底下有各种昆虫：小蚂蚁每天忙忙碌碌；小蚯蚓藏在地底下；小蚂蚱跳来跳去。
“叽叽叽”，咦？一只受伤的小鸟映入了我的眼帘。
我连忙托起它，只见它黄黄的羽毛，深红色的喙，受伤的小腿弯曲着，乌黑的小眼睛看着我，充满了痛苦。
我抚摸着小鸟，对它说：“别怕，我会帮助你的。
”我把小鸟藏在树洞里，然后跑回家拿来了药膏和纱布，我笨手笨脚的帮小鸟包扎，就像妈妈帮我包扎的那样。
小鸟朝我“叽叽”地叫唤着，好像在说：：“谢谢你。
”从那以后，我就多了一份牵挂。
一做完作业，我就带着吃的东西去看它。
妈妈觉得好奇怪：“心儿，又去哪儿玩啦？”我笑眯眯的回答：“妈妈，这是我的小秘密。
”小鸟恢复的很快，没过几天，它就能站起来了。
我把它托在手心，它就会欢快地鸣叫。
它的叫声是那么清脆悦耳。
我再一次抚摸着它，对它说：“小鸟小鸟，快快飞翔吧，天空才是你自由的家。
”我把手往空中一扬，小鸟拍着翅膀，直往上飞。
我抬起头，仰望它，它在蓝天下自由地飞翔，直至消失在我的视线里。
“小鸟，欢迎你再回来，回到那个小树洞，那是你我共同快乐的秘密！”我的小秘密三年级作文篇2我的心里有一个秘密，这个秘密就是我的理想。
我的理想是长大以后成为一个科学家。
如果长大以后真能成为一个科学家，我要发明一个时光机。
时光机可乘80人到160人，还能穿越时空，从现代来到古代和未来。
这样我们就能和古代人对话，也能看到现代已灭绝的古代动物，有了这台时光机，我们还能去看看未来的世界是什么样子的，是不是和现在一样，有春、夏、秋、冬四个季节，那时候，房子是在地上盖的，还是在天空飘浮着的？那时候还是会和现在一样环境污染如此严重？有了时光机就能看到未来的人类是怎样生活着的，是否会像小鸟那样，在天空里自由的飞来飞去，而不会像现在一样，汽车挨挨挤挤的、马路上拥堵不堪？再过几天，就是父亲节了，我们都希望自己的爸爸永远年轻、健康、充满活力。
我的小秘密三年级作文（15篇）
我的小秘密三年级作文(15篇)我的小秘密三年级作文1每当想起这件事，我心里还是一阵惊险……记得读三年级时的某一天，表姐来到了我家，正好爸爸妈妈都出去了，所以家里只有我和表姐两个人。
这时我发现餐桌上有一个化妆包，里面有一支颜色亮丽的口红。
我眼睛一亮，想到了一个怪点子：以前每次妈妈化妆时总是不让我涂她的口红，她说我人太小不能涂口红。
可是我心里还是痒痒的。
今天，总算可以让我有机会涂口红了！我拿着口红走向表姐，问她：“表姐，今天妈妈不在，我们来涂口红吧！”“好啊！” 她又说，“我来帮你涂吧！”说完，她拿起口红，打开盖子，装摸做样地给我弄起来。
表姐重重地一涂，“呀！”她大叫一声，我顿时惊慌失措，不知发生了什么事，问她：“怎——怎么了？”表姐慌张地叫起来：“口红断了！”我急中生智，赶紧把盖子盖好，放回化妆包里。
第二天一大早，表姐就走了。
妈妈像平常一样打开了化妆包，拿起了拿支亮丽的口红。
“哎呀，我的口红怎么断了，这可是我最喜欢的一支呀！”我若无其事的样子跑过去说：“昨天表姐来过了，会不会是她搞坏的呢？”因为表姐是阿姨家的女儿，所以妈妈也就不能多说什么，这场风波总算平息了。
今天我把这件事告诉大家，你们可不能告诉我妈妈哦。
这可是我的小秘密呀！虽然为此事我一直感到很羞愧，但是我还是想作为一个秘密藏在我的心里。
我的小秘密三年级作文2大家好！你们一定都有一个不为别人知道的小秘密吧！我也有一个小秘密呢，我现在就悄悄地告诉你，你可千万不要告诉别人啊！来，把耳朵伸过来。
——前言说起我的字呀，大家一定会竖起大拇指说：verygood。
那一定是说我现在的字，可我以前的字呀，那个丑就别提了，不是“点”被风刮飞了，就是“横”被陨石袭击了，不是“撇”走错了路，就是“捺”挪不了步了……唉，我的字呀！在学校里，被同学老师称为“梁体字”；在家里，被爸爸妈妈称为“自成一家”。
无奈的我只好接受了这两个“荣誉称号”谁叫咱的字乱呢？可是说心里话我真的不甘心。
我的小秘密三年级作文（通用20篇）

如何写一篇有思想、有文采的作文呢？以下是小编收集整理的我的小秘密三年级作文，仅供参考，大家一起来看看吧。
我的小秘密三年级作文篇1每个人都有自己的秘密，我也有自己的小秘密，说出来请别笑话我。
记得有一次，我去外婆家，看到外婆家有许多小辣椒，那红红的小果子挂在枝头上，真诱人。
于是我趁大人不注意，摘下一个红果子轻轻的咬了一口，顿时，我的眼泪止不住地流了出来，我便飞快地跑到外婆家的厨房拿起一杯水，就往嘴里倒，水越喝越辣，就忍不住放声大哭起来，妈妈听到我的哭声就跑过来问我说：“怎么啦？”我边哭边说，但又不敢说实话，声音还有点嘶哑。
妈妈听了，以为我感冒了，便拿来感冒药，虽然我一见这些药就反胃，但是，我不敢说出实际情况，为了不挨骂，我只好硬着头皮把药吃了下去。
当然没什么效果啦，那时候真的让我感到心有余悸。
直到现在，我还在抱怨自己为什么那么没知识，不懂好吃不好吃，还有、就是不经过大人的同意，不能随便乱吃东西，更不该说谎。
这就是我的小秘密。
我的小秘密三年级作文篇2记得小时侯奶奶常说人昏到是人的灵魂飞走了！只要用鸡蛋站站就好。
我呢半信半疑。
可后来我就不信奶奶的话了，应为有这么一件事：我和弟弟在山里的阿姨家，第二天我和弟弟去抓野兔，可刚到兔洞弟弟刚刚蹲下看看里面有没有野兔突然一只野兔从洞里飞快的地跑了出来我弟弟大叫了一声便“昏”了过去。
我连忙去叫大人。
我阿姨听了连忙放下手中的厨具跟我跑了出来，我奶奶也紧跟其后，她手上还拿了一个鸡蛋。
我弟弟当时还在“昏”死当中。
我阿姨以前是个中医，她连忙个给弟弟把脉。
我奶奶呢？在旁边立鸡蛋。
我阿姨刚把完脉，鸡蛋也立了起来。
我阿姨在旁边笑了笑，我奶奶仰天叫到“沈良锋啊，快回来啊！”叫了三遍就说已经好了等等吧。
果然过了2个小时后，我弟弟从“昏死”当中活了过来。

写身体部位的作文300
神奇的器官作文篇1今天上科学课，我了解了人体各个器官的作用。
胃就像一个神奇的皮蛋能伸能缩，还可以把我们吃下去的食物搅拌成泥，可以说它是食物的中转站。
不过有些人不爱惜自己，喜欢暴饮暴食，或者吃许多冰凉的东西，这都有可能导致胃不舒服，甚至出现疼痛的情况。
想要避免这些问题，就必须吃东西的时候细嚼慢咽，少吃冰凉的东西，还要注意合理分配好一天三餐的'时间。
那么那些食物又到哪里去了呢？其实它们进入了小肠。
小肠非常长，有人曾经测试过，如果把小肠拉直，有1栋楼那么高。
小肠那么长之所以能在我们的体内，是因为它像一条盘旋公路一样蜷缩在我们的体内。
在这里，食物会被胆汁等液体消化，时间大约需要两三小时，有用的营养会被小肠的绒毛吸收，传送到身体各处，而那些没用的残渣将会被传送到大肠。
大肠则非常宽阔，像是一条高速公路。
大肠会把所有的残渣融合在一起，让他们从粪便里排出。
看来我们的器官非常神奇，要好好的保护它们，否则它们一旦罢工，就会给我们带来许多烦恼。
神奇的器官作文篇22026年，我已经成为了一名小有名气的克隆学教授。
当时的许多人们因缺少器官而无法生存。
这时，我打算和助手进行一项实验——克隆器官。
如果克隆成功，许许多多的人们将有生存下去的机会。
这项实验很快获得了联合国的批准。
我和我的助手花了二天的时间，找到了一名即将离开人世的老爷爷。
我们先用纳米取膜器将他的眼角膜取下来，之后助手将眼角膜轻轻地放在克隆处理机上，经过一系列处理后，眼角膜成功地克隆出了第二个！这一喜讯立马传遍了全世界。
肺、肾、胃等器官开始了批量克隆，每日都有超过一万人次来自不同国家的`患者来到这里得到了治疗。
我见钱眼开，立马创办了一家公司，叫做“造福世界公司”。
我的名气立马传遍了全世界，并且在2027年年底时，超越了比尔盖茨，成功登入了福布斯世界富豪榜中的第一位！可是近几日，我的公司受到了无数消费者的投诉。
原来，我们的产品被一些工人弄虚作假，换上了粗制的肺和其它器官。
身体的秘密（精选5篇）
身体的秘密（精选5篇）身体的秘密篇1设计思路：在开展主题活动《变变变，长大了》时，有一个分题活动是“身体的秘密”。
当我们说起男女小朋友入厕的情景，立即炸开了锅。
同时，他们对两性问题表现出的早熟倾向引起了我们的关注：有的孩子在课后拉住我提了很多他关于成人生活的话题；还有的孩子在大便、小便的时候竟忍不住好奇，偷偷看对方……于是，我们决定对孩子们现阶段最为关注的话题作出正面的、积极的回应，同时对学前教育阶段如何开展启蒙“性教育”进行探索，生成了本次活动“身体的秘密”。
活动名称：身体的秘密（大班）活动目标：1、带领幼儿科学、正确地面对性话题，学会尊重自己和别人的身体。
2、有初步的自我保护意识，了解基本的防卫方法。
3、引导幼儿积极地思维，自由地表达。
活动准备：1、幼儿的准备：活动前的调查记录，对两性的区别有了初步的认识2、教师的准备：搜集大量的性教育资料，以应对课堂上孩子们的突发提问；角色分工、互助协调；布置有关两性知识的活动区角（包括人物、动物），提供较为丰富安全的可操作材料。
活动形式：集体活动、小组活动活动过程：一、谈话引入，讲解什么是“性”。
1、请小朋友按性别分成男女两组，两名老师明确分工。
2、引导幼儿通过观察，阐述自己所看到的“男、女有什么区别”，请幼儿充分讨论自己对不同性别的看法。
3、提问引发思考：什么是“性”？教师小结：“性”是和我们的身体密切相关的，不关是从头发的长短就能判断性别的，更重要的是我们身体的某些部位，是代表着性别差异的。
是哪些部位呢？就是我们穿衣服遮起来的部位。
二、明确身体的隐私部位，学会尊重自己和别人的身体。
1、请<BR><P></P>幼儿观看《蜡笔小新》，对小新随便脱裤子的行为进行讨论。
2、出示洋娃娃，请幼儿指出什么部位是要保护的，不能随便给别人看的？（用“游泳”讲解）小结：我们身体的某些部位是不能随便给别人看的，我们要尊重自己和别人的身体，因为那是我们的隐私，随便暴露自己的隐私是不礼貌的行为。
2019年我们身体上的尺秘密三年级作文
最近，数学朱老师在给我们上有关厘米和米的课，让我知道了我们身体上竟然还有“尺”！
在《认识厘米》的时候，我们认识了1厘米，1厘米有多长呢？不就是橡皮的厚，订书机的宽嘛！当老师说我们的大拇指指甲宽可能也是1厘米的时候，我立马拿起尺来，一量！真的，差不多就是1厘米！太神奇的了！可神奇的不止这！当老师介绍一拃的时候，我心里嘀咕：“这一拃有什么用呢？”接下来老师又让我们估计我们手掌的宽，有个学生说7厘米的时候，我已经偷偷的量的自己的手掌，真的，我就7厘米多点。他怎么能猜得那么准呢？有依据吗？当我听到他说：“刚才我们一拃大约14厘米，我用一拃比划了下，不就是一拃的一半嘛！”我顿时恍然大悟！
在《认识米》时，朱老师追问：“谁能知道1米大约有多长？”小朋友们有的拿粉笔来比划，有的拿着书本比划……在交流展示的时候，我张开双臂，又稍微往里弯曲一点。朱老师拿米尺帮我量了量，就比一米多出一点儿。朱老师高兴的问我为什么能比划的这么准？我说：“我知道人的双臂张开的时候和自己的身高基本是相等的，而我的也知道我的身高是1米30厘米。所以我张开双臂再稍微往里靠拢一点差不多就是一米了。”朱老师向我投来赞许的目光，接着，老师还介绍了我们身体的另一把尺——“一庹”。这一庹作用也可大了，它就比1米短些，老师让我估计黑板的长，教室的长，我都用了一庹来量一量，和实际长度可接近了！

身体的秘密
最近，我又长高了一厘米。
我高兴得一蹦三尺高，但是，我想到了一个问题：人，为什么会长高呢？
我傻傻地用拉杆绳绑在我身上，看看硬拉能不能把我拉高。
发现一开始还不痛，过了一会儿，我已经到了极限吃不消了，我就把它关了。
我去量了量，唉，一点儿也没长高。
看来这样不能让人长高。
我去问了妈妈，妈妈说：“人是在夜晚长高的，怎么长高的，我就不知道了，你要去查查资料了哦”。
人在夜晚会长高，那么人体到了夜晚又有什么小秘密呢？我去找“度娘”查一查，网上说“在胚胎发育阶段，骨头是骨干和骨髓的积聚物，髓软骨区形成新细胞，然后由软骨变成骨头直线生长，人就长高了。
夜晚睡觉时，肌肉放松，骨骼得到了自然伸展，就会长高了”。
哦，原来身体里有着这么多的奥秘，我不断长高、长大，是这些秘密武器，在帮助我。
