科普读物的读后感 篇1

伟大的诗人歌德曾经说过：”读一本好书，如同跟一个高尚的人谈话。“是啊，一本好书会使我们受益匪浅。我一直喜欢看图文并茂、情节曲折生动的童话书，使我在一个又一个小故事中明白许许多多深刻的大道理的寓言书，但我现在也喜欢看科普读物了。呀，不看不知道，一看吓一跳呢！科普读物蕴藏着神秘和奇妙，所以一下子吸引了我，从终日忙碌的燕子那里，我认识到勤劳的可贵；从飞行整齐的大雁那里，我懂得了纪律的重要；从博击风雨的苍蝇那里，我学到了勇敢顽强的精神；从不辞劳苦的啄木鸟那里，我体会到了救死扶伤的快乐……还有，比如为什么电信号能传递到很远的地方，为什么电冰箱能制冷，为什么导弹能飞很远等等。

The great poet Goethe once said, "Reading a good book is like talking to a noble person.". "Yes, a good book will benefit us a lot. I have always liked to read fairy tales with rich pictures and texts and lively plots, and fables that enable me to understand many profound truths in one small story after another. But now I also like to read popular science books. Ah, I don't know if I don't read them. It's a surprise to see them! Popular science books contain mystery and wonder, so they suddenly attracted me. From the busy swallows, I think Recognize the value of hard work; From the flying geese, I learned the importance of discipline; From the flies that beat the wind and rain, I learned the spirit of courage and tenacity; From the hardworking woodpeckers, I learned the joy of saving lives... and why electrical signals can be transmitted to far places, why refrigerators can cool, why missiles can fly far, and so on.

还让我知道了微波炉不喜欢与金属做伴，因此，用微波炉加热的食物，不能使用金属容器。知道了我们的身体是由细胞这种很小的东西构成的。而细胞是由细胞膜，细胞质，高尔基体和中心粒组成的。我们身体里有200多根骨头，骨头是由活细胞和矿物质混合组成的，如果，我们的骨头断了，可以通过打石膏，把它们重新接上。打石膏是为了防止断裂的骨头在愈合过程中移动从而造成错位。

I also learned that the microwave oven does not like to be accompanied by metal, so the food heated by the microwave oven cannot use metal containers. We know that our bodies are made up of such small things as cells. The cell is composed of cell membrane, cytoplasm, Golgi apparatus and centriole. There are more than 200 bones in our body, which are composed of living cells and minerals. If our bones are broken, they can be reconnected by casting. Plaster is used to prevent the broken bone from moving during the healing process and causing dislocation.

啊！读了科普读物让我重新认识了地球，我想我要继续探索这奇妙的地球，并把这些知识告诉同学，让他们知道生活在这如此多姿多彩的地球！

Ah! After reading popular science books, I have a new understanding of the earth. I think I will continue to explore this wonderful earth, and tell my classmates about this knowledge, so that they can know how to live on such a colorful earth!

物理读后感 篇2

暑假里，妈妈给我买了一套《这就是物理》科普读物。当我读到《热》这一本时，我被迷住了。这本书里介绍了很多热源。比如，太阳是地球上最重要的热源，地球上的生命离不开太阳传递热量；地球内部也有热源；还有一种热源，就是当两个物体摩擦时，物体自身能量增加使温度升高所产生的热量，这也叫摩擦生热……

During the summer vacation, my mother bought me a set of popular science books called "This is Physics". When I read Hot, I was fascinated. This book introduces many heat sources. For example, the sun is the most important heat source on the earth, and life on the earth cannot do without the sun to transfer heat; The earth also has heat sources inside; There is also a heat source. When two objects rub, the heat generated by the increase of the object's own energy makes the temperature rise, which is also called friction heat generation

书中最令我情有独钟的要属热胀冷缩的这一章节了。其中讲到了我们熟悉的温度计。当温度升高时，温度计管子里的红色液体会受热膨胀和上升；当温度下降时，红色液体便会沿着管壁下降。这样我们便能及时了解温度的变化。这也是利用了热胀冷缩的原理。

In the book, what I like most is the chapter of heat expansion and cold contraction. We are familiar with thermometers. When the temperature rises, the red liquid in the thermometer tube will expand and rise due to heat; When the temperature drops, the red liquid will fall along the pipe wall. In this way, we can know the change of temperature in time. This is also based on the principle of thermal expansion and cold contraction.

生活中我常常能观察到这一神奇的变化。有时候妈妈会蒸一些馒头、包子。当它们在蒸锅里时，一个个白白胖胖的，可爱极了。不过，等把它们从锅里拿出来放凉后，它们都好像不愿意出锅似的，一个个变成了苦瓜脸。

I can often observe this magical change in my life. Sometimes my mother will steam some steamed buns and steamed buns. When they are in the steamer, they are fat and cute. However, when they were taken out of the pot to cool, they all seemed unwilling to leave the pot and turned into bitter gourd faces one by one.

当然，我们还可以利用这一原理帮助我们解决一些小麻烦呢！比如，在打乒乓球时，你不小心把球踩扁，可千万不要懊恼，把它扔到垃圾箱。你可以利用热胀冷缩来解救这个可怜的乒乓球。只要一杯热水，再把瘪了嘴的乒乓球放入热水中，你会发现，它正使劲鼓起腮帮子呢。不一会儿，它就找回了自己原本圆溜溜的可爱模样。还有，如果你想剥出一颗滑溜溜的完整的煮鸡蛋，也可以利用这一原理，煮好后把它迅速投入冷水中，这样，蛋白遇冷收缩，就能轻而易举地剥出来了。

Of course, we can also use this principle to help us solve some small problems! For example, when playing table tennis, if you accidentally squash the ball, do not be upset and throw it into the dustbin. You can use heat expansion and cold contraction to save this poor ping-pong ball. Just a cup of hot water, and then put the shrunken mouth table tennis ball into the hot water. You will find that it is puffing its cheeks. Soon, it found its original round and lovely appearance. Also, if you want to peel a smooth and complete boiled egg, you can also use this principle to quickly put it into cold water after cooking, so that the protein can easily peel out when it shrinks.

你看，热胀冷缩是不是很神奇呢？快用你的小眼睛去发现它吧！

You see, is it amazing to expand with heat and contract with cold? Use your little eyes to find it!

科普读物读后感 篇3

今日，我读完了《植物揭秘》这本书，了解了很多关于植物的资料，也看到了大自然的奇妙之处。

Today, after reading the book "Uncover Secrets of Plants", I learned a lot about plants and saw the wonders of nature.

这本书的主题主要是“草药植物”、“植物的秘密”、怪异植物“植物世界的吉尼斯”、“沙漠植物”、“植物习性”。我对这些主题都很感兴趣，原先植物世界也有这么多东西能够探索。我就说一下我最感兴趣的的“植物世界的吉尼斯”吧。

The main themes of this book are "herbal plants", "secrets of plants", weird plants "Guinness of the plant world", "desert plants", and "plant habits". I am very interested in these topics. There are so many things in the original plant world that can be explored. Let me tell you about the Guinness of the Plant World that I am most interested in.

俗话说“人生七十古来稀”，人只要活到七十岁以上就算不错了。可是在树木面前人类界的长寿简直是一只微不足道的“小蚂蚁”。世界上最长寿的树是非洲西部加那利岛上的一颗龙血树。五百多年前，西班牙人测定它大约有8000~10000岁。可惜在之后的一次风灾中毁了。

As the saying goes, "life is rare in 70 years." It's good if you live to be over 70 years old. But in front of trees, the longevity of the human world is a negligible "little ant". The oldest tree in the world is a dracunculus dracunculus on Canary Island in western Africa. More than 500 years ago, Spaniards determined that it was about 8000~10000 years old. Unfortunately, it was destroyed in a subsequent storm.

植物界中还有命很短的“短命鬼”，瓦松。瓦松是长在瓦房顶上的植物。只要等到雨季一来，它为了“能多活几天”，就迫不及待地发芽生根，开花结果，繁殖了自我的后代，随后就是“等死”了。只要雨季一过，它便很快枯黄死去，结束了生命历程。

There is also a short-lived ghost in the plant world, Vasone. Vason is a plant growing on the roof of tile roofed houses. As long as the rainy season comes, in order to "live a few more days", it can't wait to sprout and take root, blossom and bear fruit, reproduce its own offspring, and then "wait to die". As long as the rainy season is over, it will soon wither and die, ending its life course.

还有更绝的树。铁刀木，它的种子都刀斧难入，可想而知它长成后的身体有多么坚硬了。铁刀木的硬度可达每平方厘米656~698千克，用斧子去砍它竟还会迸出火花。

There are even more amazing trees. Iron sabre wood, its seeds are hard to enter. You can imagine how hard its body is when it grows. The hardness of the iron sabre wood can reach 656~698 kg per square centimeter, and even sparks can burst out when you cut it with an axe.

水瓶树，对待火就像一个小儿科的把戏似的，毫不放在眼里。他高大粗壮，主干高达几十米，酷似一个巨大的水桶。其实真能够说它是水桶。它的藏水量可达一吨多。即使来了火灾把附近的植物都烧光了，它也只可是损伤几根枝条树叶而已。

Aquarius tree, treating fire like a trick of children, does not pay attention to it. He is tall and sturdy, and his trunk is tens of meters high, just like a huge bucket. In fact, it can be said that it is a bucket. Its water storage capacity can reach more than one ton. Even if the fire burns all the nearby plants, it only damages a few branches and leaves.

看吧，光植物就有这么多奇妙的东西，那么大自然呢？至今世界上还有很多都没有被发现的科学事物，而身为祖国期望的我们又何尝不能将它们一一发现呢？

Look, there are so many wonderful things in plants alone. What about nature? So far, there are many scientific things that have not been discovered in the world, and why can't we find them one by one as our motherland expects?
