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。
