Unit 1 The Amazing Octopus
Among the many amazing animals in the world, few are as strange and unusual as the octopus. There are around 300 different kinds of octopuses, and they come in all sizes! The smallest is only around 2.5 centimeters long, but some octopuses can grow up to more than five meters long. There was even an octopus over nine meters long!
The octopus’s body is very interesting. All octopuses have eight arms.Their brain is not just in their head, but also in their arms! This helps them to think about and do more than one thing at once.
Octopuses can also fit into small places because they do not have any bones! And did you know that octopuses have three hearts? These hearts work with different parts of the body.
Octopuses can also do many amazing things. They can change how they look. They can change their colour and shape to look like plants or other sea animals. Octopuses can also make ink. They keep it inside very small bags in their body. When they produce ink, the ink makes it hard for other animals to see them. This helps octopuses to get away fast. What’s more, when an octopus loses an arm, it can grow it back!
Studying amazing animals like the octopus is important because we can learn a lot from them. But they also show us how wonderful nature is and why it is important to protect it!

章鱼的身体很有趣。所有的章鱼都有八只手臂。它们的大脑不仅在头部，还在手臂!这有助于它们同时思考和做多件事情。
章鱼还能钻进狭小的地方，因为它们没有骨头!你知道章鱼有三个心脏吗?这些心脏与身体的不同部位协同工作。
章鱼还能做很多神奇的事情。它们可以改变自己的样子。它们可以改变自己的颜色和形状，让自己看起来像植物或其他海洋动物。章鱼还能制造墨汁。它们把墨汁保存在体内一个很小的袋子里。当它们制造墨汁时，该墨汁使其他动物很难看到它们。这有助于章鱼快速逃走。此外，当章鱼失去一只手臂时，它还能重新长出来!
研究章鱼这种神奇的动物非常重要，因为我们可以从它们身上学到很多东西。但它们也向我们展示了大自然是多么美好，以及为什么保护大自然很重要!
