When it rises again the following morning, that field has been changed into a huge work of art. A large part of the crop (庄稼) has been pressed into a pattern of circles, squares and other shapes. Farmers have reported finding strange circles in their fields for centuries. The earliest mention of a crop circle dates back to the 1500s. Crop circles, however, didn’t get attention until 1980, when a farmer in England discovered three circles in his field. The world first began to learn about crop circles. By the 1990s, crop circles had become something of a tourist attraction. In 1990 alone, more than 500 circles appeared in Europe. Within the next few years, there were thousands. Crop circles can come in many different shapes, changing in size. Most early crop circles were simple. But after 1990, the circles changed. Crops can be made to look like just about anything—smiling faces, flowers or even words. People have long been wondering who or what is creating these crop circles. Possibly the most widely known idea is that crop circles are the work of visitors from other planets. Probably the most scientific opinion says that crop circles are created by vortices (涡旋). They force the air down to the ground, which presses the crops down. Dr. Terence Meaden, an expert, says when the dust (沙尘) gets caught up in a vortex, it can appear to glow (发光), which may explain the UFO-like glowing lights many people have seen. 1. How does the writer introduce the topic of the passage? A. By telling a story. B. By asking a question. C. By giving a comparison (比较). D. By describing a scene (场景). 2. When did the world become interested in crop circles? A. In the 1500s. B. After 1980. C. In 1900. D. After 1990. 3. Which of the following is TRUE about crop circles in Paragraph 4? A. Early crop circles were very small in size. B. Large crop circles were usually round in shape. C. Crop circles of all kinds began to appear after 1990. D. Flower-shaped crop circles were first found in the 1500s. 4. Which point do you think Dr. Terence Meaden would agree with? A. Crop circles may be man-made. B. Crop circles could be marks left by aliens. C. The UFO-like light could be caused by dust. D. Vortices are sure to create perfectly shaped crop circles. 5. What would be the best structure of the passage? A. B. C. D. 【答案】DBCCA 【导语】本文是一篇说明文。主要介绍了麦田怪圈的相关信息。 1. 细节理解题。根据“The sun sets on a field in southern England. When it rises again the following morning, that field has been changed into a huge work of art. A large part of the crop has been pressed into a pattern of circles, squares and other shapes.”可知，此处描述了麦田怪圈形成的场景。故作者通过描述场景来介绍文章的话题。故选D。 2. 细节理解题。根据“didn’t get attention until 1980”可知，1980年后，人们才开始对麦田怪圈感兴趣。故选B。 3. 细节理解题。根据“But after 1990, the circles changed. Crops can be made to look like just about anything—smiling faces, flowers or even words.”可知，1990年以后，各种各样的麦田怪圈开始出现。故选C。 4. 细节理解题。根据“Dr. Terence Meaden, an expert, says when the dust gets caught up in a vortex, it can appear to glow, which may explain the UFO-like glowing lights many people have seen.”可知，类似不明飞行物的光可能是由灰尘引起的。故选C。 5. 篇章结构题。通读全文可知，第一段总领全文，通过描述现象引出下文麦田怪圈；第二段和第三段介绍了麦田怪圈的发展；第四段介绍了麦田怪圈的形状；第五段和第六段介绍了麦田怪圈的形成原理。结构为①/②③/④/⑤⑥。故选A。 B Known as Earth’s “kidneys” (肾), wetlands play an important part in the ecosystem (生态系统). However, about 35% of natural wetlands have been lost in the past 50 years, said the UN. Hoping to do their part in wetland protection, Lyu Haoyan and Cui Luoyao, two 14-year-old girls from Beijing made a mudskipper amphibious robot (弹涂鱼两栖机器人). They won the Gold Award of the 19th Soong Chingling Award for Children’s Invention on Aug 17. “We wanted to make a simple robot to help collect data (数据), but traditional robots faced problems in wetlands,” Cui told Teens. As an amphibious fish, mudskippers are small and can move freely in wetlands. Inspired (启发) by the little creature, they added a special chest (胸腔) and tail fin (鳍) to their robot. The fin can help the robot move freely on land and swim underwater. They also learned coding (编程) to control the robot with their phones from far away, up to 300 meters. What’s more, they put in different sensors (传感器) to see plants and check water cleanness. But things didn’t always go well. How to keep the main electronics (电子元件) dry when the robot went underwater was a big problem during testing. “The 3D printed parts we used couldn’t seal (密封) well,” Lyu told Teens. After trying different methods, they found that placing rubber (橡胶) rings in the gaps (缝隙) worked well to stop water from getting in. After successfully controlling their robotic mudskipper on land and underwater, they were happy with their success. “I feel so proud because our robot can help look into the places that people cannot reach,” said Cui. 1. Why did Cui Luoyao and Lyu Haoyan made the robot? A. To protect wetlands. B. To finish their schoolwork. C. To deal with water pollution (污染). D. To learn more about amphibious fish. 2. What does “the little creature” in Paragraph 4 refer to? A. Mudskippers. B. The inventors. C. The robot fish. D. Wetlands. 3. Why did the girls choose to make the robot based on (基于) a mudskipper? A. Because mudskippers can clean the water. B. Because mudskippers can talk on the phones far away. C. Because mudskippers would make the robot look cool. D. Because mudskippres can move freely on land and in water. 4. How did the girls keep the electronics dry when it was underwater? A. By sealing the robot with tape. B. By adding a special cover to it. C. By using more 3D printed parts. D. By putting rubber rings in the gaps. 5. What would be the best title for the passage? A. The Importance of Wetlands. B. How Sensors Help in Wetlands. C. Difficulties in Studying Wetlands. D. Students Build Robot to Save Wetlands 【答案】AADDD 【导语】本文是一篇记叙文，主要讲述了崔洛瑶和吕昊妍设计了一种可以保护湿地的机器人。 1. 细节理解题。根据“Hoping to do their part in wetland protection, Lyu Haoyan and Cui Luoyao, two 14-year-old girls from Beijing made a mudskipper amphibious robot.”可知，崔洛瑶和吕昊妍制造了这个机器人是为了保护湿地。故选A。 2. 词句猜测题。根据“As an amphibious fish, mudskippers are small and can move freely in wetlands. Inspired by the little creature, they added a special chest and tail fin to their robot.”可知，作为一种两栖鱼类，弹涂鱼体型小，可以在湿地中自由移动。受这个小生物的启发，她们在机器人上增加了一个特殊的胸腔和尾鳍。因此，“the little creature”指的是弹涂鱼，故选A。 3. 细节理解题。根据“As an amphibious fish, mudskippers are small and can move freely in wetlands. Inspired by the little creature, they added a special chest and tail fin to their robot.”可知，这说明女孩们选择以弹涂鱼为原型制作机器人是因为它能在陆地和水中自由移动，故选D。 4. 细节理解题。根据“After trying different methods, they found that placing rubber rings in the gaps worked well to stop water from getting in.”可知因此，女孩们通过在缝隙中放置橡胶圈来保持电子元件在水下干燥，故选D。 5. 最佳标题题。文章主要介绍了两名北京14岁的女孩为了保护湿地，制作了一个弹涂鱼两栖机器人，并详细介绍了制作过程和遇到的困难。因此，最能概括文章主旨的标题是Students Build Robot to Save Wetlands“学生制造机器人拯救湿地”。故选D。 1 / 14 学科网（北京）股份有限公司 $$ 2024-2025学年度沪教版英语7年级 下 Unit 3 主题内容 学习目标 主题范畴: 人与自然→环境保护→热爱与敬畏自然，与自然和谐共生 主题内容： 围绕话题trees and us，了解树木为我们做的事，识别有关树木的令人惊叹的事实，描述为了保护树木我们能做的事。 1. 语言知识: （1）能认读音标/bl/ /br/ /fl/ /fr/ /gl/ /gr/ /kl/ /kr/，并辨识发这些音的字母或字母组合； （2）能口头谈论如何拯救树木，能写植树脚本。 2.语言技能：能听懂和树木有关的对话或短文，能谈论树木对人的重要性，能读懂以树木为话题的语篇，能写脚本报道植树节。 3.学习策略: 能小组合作，讨论拯救树木的方法。 4.文化意识:学完本单元后，学生能够了解树木的重要性，了解中国的茶种植历史和茶文化。 自主学习任务一：背默词汇 一、重点单词 ① 名词 1. n. 产品 2. n. 一面 3. n. 洞，孔 4. n. 棍，条 ② 动词 1. v. 借用 2. v. 掘（地），（凿）洞 二、重点词汇 1. 号召 2. 砍倒 3. 挖一个深坑 4. 把某物种植到…… 三、重点句型 1. 号召人们停止砍伐树木。 people to stop trees. 2. 我们应该找方法去使用更少的纸。 We should find less paper. 3. 我们应该双面写字或打印。 We should write or . 4. 当吃水果时，想想种植它的人。 When eating the fruit, the person who grew it. ►问题一：音标/bl/ /br/ /fl/ /fr/ /gl/ /gr/ /kl/ /kr/的常见字母组合有哪些？ 【点拨】 音标 常见发音的字母组合 /bl/ bl: black trouble /fl/ fl: butterfly flower /gl/ gl: glass glue /kl/ cl: clean clever /br/ br: branch breathe /fr/ fr: fresh fruit /gr/ gr: grade grow /kr/ cr: across crazy 【典例】选出划线部分发音不同的选项 1.
