二、完形填空
Octopuses (章鱼) are kind of like aliens. They are 1 in many ways. They have three hearts. They can walk, they can swim, and they can drive themselves forward at high speed. They can change colour and copy what other animals do. They even know how to open screw-top jars (有螺旋盖的罐子) and how to 2 tools!
Octopuses are mollusks (软体动物). But unlike many other mollusks, they don’t have a shell (壳). This allows them to pass through tiny spaces. Although octopuses 3 eat small fish, they are able to attack and kill small sharks. They make the sharks unable to breathe by covering their gill (鳃) openings.
One thing that makes octopuses seem like aliens is their blue blood. It is much better at transporting oxygen (氧气) in cold and low oxygen conditions (like the deep sea) than our 4 blood. Octopuses lose energy easily. This may help explain their outstanding intelligence: They can’t chase after their prey (猎物) for a long time. They must use 5 tricks.
As a 6 , an octopus brings its prey under control through the use of a powerful poison (毒素). The smaller the octopus, the stronger the poison. The ten-centimetre-long blue-ringed octopus is so poisonous that it can easily 7 an adult. Octopuses themselves can be delicious prey to many different animals in the sea, but they are clever enough to know how to keep themselves safe most of the time. With their colour-changing skin, octopuses can easily “hide” themselves or flash alarming colours to frighten their enemies away. If that doesn’t work, the octopus will release a cloud of dark ink and quickly 8 .
Perhaps the most amazing part of an octopus is its arms. They can turn in any 9 . The arms are too complex to be controlled by a central brain. Instead, they work almost independently. An octopus gives instructions and believes that they will be carried out. This means that the animal doesn’t have a very good idea of where its arms are. They can’t 10 the shape of something by feeling it, like we can.
1．A．difficult B．amazing C．energetic D．rare
2．A．use B．create C．close D．design
3．A．specially B．slowly C．quickly D．mainly
4．A．yellow B．blue C．red D．pink
5．A．clever B．interesting C．strong D．exciting
6．A．hunter B．worker C．player D．manager
7．A．catch B．watch C．kill D．kick
8．A．pick up B．take away C．get up D．get away
9．A．protection B．direction C．action D．decision
10．A．come out B．turn out C．work out D．blow out
三、阅读理解
A
Do you know a mountain that looks like big steps
That’s Batai Mountain, an amazing place in Dazhou, Sichuan.
The name “Batai” means “eight terraces (台阶)” because it looks like it has eight huge flat steps going up. It’s very tall (over 2,200 metres). Because it’s so high, it’s one of the first places in Sichuan to see the sunrise each morning. Watching the sun come up from the top is amazing.
For nature lovers, Batai Mountain is a good place to visit. You can see fantastic deep valleys, interesting rock shapes, and big forests all around. On the fine mornings, there are thick (厚的) clouds covering the land below, making the tops of the mountain look like islands in a huge white sea. And if you’re brave enough, you can even walk on special paths (小路) with glass parts high above the ground—it feels just like walking in the sky.
Batai Mountain is a natural geopark (地质公园) protected by the government. It’s a very important and beautiful place. Whether you like hiking, taking amazing pictures, or just seeing cool natural sights, Batai Mountain is an unforgettable place to visit. It’s Dazhou’s natural wonder.

五、回答问题
A retired postman from Türkiye and a beautiful white swan have been together for nearly forty years, and the story of their friendship has warmed the hearts of millions of people.
In 1984, Recep Mirzan was in a car with a group of friends when he saw a swan that appeared to have a broken wing in an empty field.
Mirzan quickly realized that leaving the bird there was the same as signing its death sentence, for meat-eating animals would have most likely eaten her, so he stopped the car and took the bird with him. He kept her in the car until evening. Then he took her home and started nursing her back to health.
“Since I love animals, I should take her home instead of leaving her as dinner to foxes,” Mirzan said. “We get used to each other. We never separate.”
Even after the swan’s broken wing healed (痊愈), she didn’t fly away. Instead, she acted as a friend to the other animals on Mirzan’s farm, and decided to stick around. Mirzan named her Garip and now she has been with him ever since.
“She comes when I call her. Since 1984, she has never left me, not even during the river floods,” the retired postman said. “She used to be stronger, but she has grown old now. If she dies, I will make her a nice grave (墓穴) here, but I hope we spend more time together.”
She is busy following her human friend around, either during his daily chores, or on his evening walks.
After his wife died a few years ago, Recep Mirzan started spending more time with his animals. Since he has no human children, he regards Garip as his child.
根据短文内容，回答问题。(每题答案不超过16个词)
1．Who found a swan with a broken wing
2．Why did the man take the swan home
3．What did the swan do when her broken wing healed
4．How long has the swan lived with the man
5．What do you think of Recep Mirzan

Protect the natural world
Good morning, everyone! Today I am very happy to be here to give a talk about protecting the natural world.
The natural world belongs to all of us. I think everybody should take on the responsibility of environmental protection. There are many environmental problems nowadays. For example, people cut down trees for production. Rubbish is often thrown into rivers and lakes, and many of them are polluted. Luckily, there are many things we can do to protect the natural world. We should sort the rubbish into different groups so that it can be reused and recycled better. Besides, we should learn to save energy, such as not leaving taps running all the time.
Let’s take action to save our world together!
That’s all. Thanks for your listening.
