Many people love them for their cute appearance—round eyes and soft grey fur. But there’s more to these animals than just being cute.​ Koalas live in eucalyptus forests in eastern Australia. They spend almost all their time in trees, even sleeping and eating there. Their strong claws help them climb trees easily. Koalas mainly eat eucalyptus leaves. There are over 600 kinds of eucalyptus trees, but koalas only like about 30 kinds. They can eat up to 1 kg of leaves a day!​ Eucalyptus leaves are not very nutritious, so koalas need to save energy. That’s why they sleep for 18 to 20 hours every day. When they are awake, they spend most of the time eating. Koalas don’t drink much water because they get enough from the leaves. The word “koala” even means “no water” in an old Australian language.​ Sadly, koalas are in danger now. Their homes are disappearing because people are cutting down eucalyptus forests. Wildfires also kill many koalas and destroy their habitats. We must protect these lovely animals before it’s too late.​ 1.What do koalas look like?​ A. They have long legs and black fur.​ B. They have round eyes and soft grey fur.​ C. They have sharp teeth and big ears.​ D. They have thin bodies and short tails.​ 2.Where do koalas live?​ A. In deserts of Australia.​ B. In eucalyptus forests in eastern Australia.​ C. In mountains of central Australia.​ D. In rainforests of western Australia.​ 3.Why do koalas sleep so much?​ A. Because they are lazy animals.​ B. Because eucalyptus leaves have little nutrition.​ C. Because they don’t have much to do.​ D. Because they are afraid of humans.​ 4.What does the word “koala” mean in an old Australian language?​ A. No water.​ B. Tree lover.​ C. Sleepy animal.​ D. Grey fur.​ 5.What is making koalas in danger?​ A. Lack of sunlight.​ B. Too much rain.​ C. Deforestation and wildfires.​ D. Pollution and hunting.​ 九、任务型阅读​ Jellyfish are amazing sea creatures that have lived on Earth for over 600 million years—even longer than dinosaurs! They can be found in oceans all over the world, from warm tropical waters to cold Arctic seas.​ Jellyfish have very simple bodies. They don’t have brains, hearts or bones. Most of their bodies are made of water. Their shape looks like a transparent umbrella, and they have long tentacles around the edge. These tentacles are very important—jellyfish use them to catch food like small fish and shrimp. The tentacles have tiny stingers that can paralyze prey.​ Jellyfish move in a special way. They push water out of their bodies quickly, which makes them move forward like a rocket. Some jellyfish are very small, only a few millimeters wide. Others can be very big—their umbrellas can be over 2 meters across, and their tentacles can reach 30 meters long!​ Although jellyfish are beautiful, they can be dangerous. Their stings can hurt humans. But most jellyfish stings are not serious—they just cause redness and pain.​ Answer the following questions:​ 1. How long have jellyfish lived on Earth?​ 2. Where can jellyfish be found?​ 3. What do jellyfish use their tentacles for?​ 4. How do jellyfish move?​ 5. Are all jellyfish stings serious?​ 十、作文​ 假设你在自然课上了解到了考拉的神奇之处，老师让你分享对考拉的认识及保护建议。请根据以下提示写一篇短文：​ 提示：1. 介绍考拉的外形和生活习性；​ 2. 说明考拉面临的危险；​ 3. 提出保护考拉的具体措施。​ 要求：1. 词数 80-100；​ 2. 语句通顺，语法正确；​ 3. 文中不得出现真实姓名和校名。​ ​​ 参考答案​ 一、根据句意及首字母或汉语提示完成单词​ 1.eucalyptus 2. transparent 3. protect 4. attract 5. ability 6. tentacles 7. than 8. carrying 9. habits 10. habitats​ 二、单词词性转换​ 1.happier 2. danger 3. quickly 4. alive 5. beautiful 6. protection 7. sleepy 8. slowly 9. carefully 10. dying​ 三、单句语法填空​ 1.older 2. sleeping 3. most dangerous 4. to save 5. softer 6. bring 7. easily 8. were cut 9. fewer 10. learning​ 四、单项选择​ 1.B 2.
