It suddenly dived towards the ground. She heard a noise and saw a red light.The next morning, Tina mentioned it to her brother Tom. “I’m sure something landed inthe forest near the hills as I heard a loud noise last night,” she said.“Let’s explore after school.”At 6 p.m., Tina and Tom reached the forest. They heard some voices speaking a strange language, so they hid behind some bushes and kept quiet.Then they saw an alien! It was tall,with a round head and a silver body. It was standing next to a long spaceship. The spaceshipwas damaged because of a crash. The children were frightened. Suddenly, another alienappeared from the bushes infront of them. It discovered them and made a terrible noise! The children ran away in fear.The next morning, Tina and Tom told their parents about the strange creatures. “They were very ugly. They had some hair,but they didn’t have any feathers,” said Tina.“There was something written on the spaceship,” said Tom, “ Itlooked like this, I wonder what it means,” He drew some lines on a piece of paper.But Dad said, “Since no one else saw these aliens, I refuse to believe you. Now go to school!The children spread their wings and flew to school together.Dad looked at the piece of paper with the strange marks on it. “It looks strange,” he said, as he looked at the word “EARTH”. More PracticeUFOMany people say they have seen UFOs. Here is one famous story. It is called the Roswell Incidentand it happened in the US in 1947.Person A (name not given): My wife and I were sitting outside because it was a warm night. Suddenly we saw something very bright flying through the sky. Person B (William Brazel, a farmer): I found some pieces of strange metal on my farm. I called the army. Major Marcel came and collected the pieces. He told me not to talk to anyone about this.Person C (Major Marcel): I went and collected the pieces. I gave them to an army expert. He said the pieces came from a weather balloon. However, since I have not seen this kind fo metal before, I think this was a lie.Person D (name not giver): My parents and I were in the countryside. Suddenly we saw a silver spaceship on the side of the hill. There were the bodies of three aliens lying on the grass. Then some soldiers came and told us to leave.So what is the truth?●Perhaps some or all of the people lied.●Perhaps a US rocket crashed and people thought it had come from space.●Perhaps an alien spaceship really crashed in Roswell.一、教材分析本单元围绕着“未知的世界”的话题来展开听、说、读、写的训练。

八年级英语下册第7单元知识点和作文As we delve into the seventh unit of the Grade 8 English textbook, we embark on a journey that explores the fascinating world of would-be inventions and theirpotential to revolutionize our lives. This unit, titled "Would you mind keeping your voice down?", opens up a discussion on the importance of polite requests and apologies in everyday communication. It encourages students to consider how they can use language effectively to express their needs and desires while respecting the feelings of others.The knowledge points in this unit cover a range of grammatical concepts, including the use of modal verbs to express requests and apologies, as well as practice in writing polite requests and apologies in different scenarios. Students are introduced to the structure of polite requests, such as "Could you please...?" and "Would you mind...?", and are challenged to apply this structureto real-life situations, practicing their ability to communicate effectively and diplomatically.The writing component of this unit focuses on imaginative writing, asking students to create their own would-be inventions and describe them in detail. This exercise not only tests their understanding of the grammar and vocabulary learned in the unit, but also theircreativity and ability to present ideas clearly and concisely. Students are encouraged to think outside the box, envisioning inventions that could potentially solve real-world problems and improve people's lives.In the realm of vocabulary, the unit introduces new terms related to inventions and technology, such as "inventor," "invention," "robot," and "machine." Students are expected to not only recognize and understand these words but also use them effectively in their writing. This expanded vocabulary helps them to express more complexideas and concepts, enhancing their overall language proficiency.The combination of grammar, vocabulary, and imaginative writing in this unit provides students with a comprehensivelearning experience that is both challenging and engaging. By practicing polite requests and apologies, they learn to communicate more effectively with others, while the exercise in imaginative writing stimulates their creativity and critical thinking skills.In conclusion, the seventh unit of the Grade 8 English textbook is a rich and diverse learning resource that covers a wide range of language skills and concepts. It challenges students to push their boundaries, think critically, and communicate effectively, while also nurturing their imaginations and creativity. Through this unit, students gain valuable insights into the power of language and its role in shaping our interactions with the world.**解锁八年级英语下册第七单元的秘密**当我们深入八年级英语下册的第七单元时，我们踏上了一段探索未来发明及其有可能改变我们生活的潜力的奇妙旅程。
