原文速记：
Crop circles The crop circle phenomenon has puzzled and mystified humanity for many years. The designs just appear, placed carefully in fields of food grains. Some are larger than football fields and highly complex in design and construction. Others are smaller and more primitive. We call them crop circles, but many of them are not circular. Some are elongated abstract designs, a few resemble insects or other known forms, and some are mixtures of lines, circles, and other shapes melded into intricate patterns. Most become visible overnight, though it has been claimed that a few have appeared within a half-hour in broad daylight. Crop circles have appeared all over the world. About 10,000 instances from various countries have been reported in recent years. The first modern rash of crop circles appeared in Australia in December of 1973. A strange circular imprint appeared in a wheat field near Wokurna, a community southeast of Adelaide. Soon seven swirled circles up to 14 feet in diameter appeared in an oatfield nearby. In December of 1989, an amazing set of circles, ranging from a few inches to a few feet in diameter appeared in the wheat best west of Melbourne. As many as 90 crop circles were found. The best documented and largest modern spread of crop circles began in southern England during the summer of 1980. By the end of 1988, 112 new circles had been formed. At that time circles were being reported worldwide, 305 by the end of 1989. The total grew to an outstanding 1,000 newly-formed circles in 1990. In 1991, 200 to 300 circles were reported. Crop circles have been documented in over 30 countries, including Canada, the former Soviet Union Japan and the United States. Nine out of ten circles remained simple with broken stems flattened to the ground and swirled. The stalks around the circles remained completely erect. But over the years, crop circles have become much more geometrically intricate. Patterns involved multiple circles, bars, triangles, rings and spurs. Pictorial imagery also appeared. Reliable eyewitnesses have reported seeing unusual lights and hearing unidentifiable sounds while on an early-morning walk in the countryside where a crop circle showed later that day. High pitched, warbling, noises have been recorded at the site of some crop circles. On several occasions a strange glow or a darker colouring has been seen in the Access https://ieltsonlinetests.com for more practices page 6 sky over a crop circle. And in more than one instance, the electrical power of small planes flying overhead has been cut off abruptly. While the causal energies do not seem to harm animals, or even insects as far as we can tell, wild creatures tend to avoid the circles. Flocks of birds have been seen to split apart and fly around the perimeter to avoid going directly over a crop circle formation. Researchers have spent a great deal of time investigating different aspects of crop circles. They try to detect traces of human involvement in the circle making, test the area of the circle itself for geophysical anomalies, and analyze the field’s grain both from within and outside the circles, searching for differences. Dr. W. C. Levengood of BLT Research in Cambridge, Massachusetts, has analyzed many grain samples and confirmed, time after time, significant changes at the cellular level of crop circle plants. The plants in front of the circles have elongated cells and blown-out growth nodes. Seeds front the circle plants often show accelerated growth rates when they are sown, and in some instances, quite different-looking plants result. In many instances it appears that a vortex-like energy causes the plants to swirl down, flattening the design into the land. Whatever this energy is, it does not generally inhibit the plants’ growth. They continue to show normal response to the sun, raising upward over several days following the appearance of the circle. Michael Chorost of Duke University found occasions of short-lived radionuclides in the top layer of soil in some of the formations. A British government laboratory found diminished nitrogen and decreased nematode populations as well as decreased water content in the soil of a formation. Researchers have discovered other anomalies as well, such as curious embedded magnetic particles and charred tissue. Some of the plant stalks within the circles show evidence of being exposed to rapid microwave heating. Scientists have attempted to explain crop circles as a result of natural processes. One popular theory accepted by many mainstream scientists and academics is known as ‘Plasma Vortex Theory’. Developed by Dr. Terence Mearden, it theorizes that electrified air (plasma), on the side of hills, becomes mini-tornadoes and screws down onto the ground, creating the circles. The theory also holds that the electrified air would cause a light to appear above the circle and therefore account for UFO sightings. Although this theory still has considerable support, it has come under fire because of the highly intricate and complex crop circle patterns that have appeared since 1991. Another theory is that the circles are all hoaxes or practical jokes. Major support came to this theory when, on September 9, 1991, two Englishmen claimed to have created Access https://ieltsonlinetests.com for more practices page 7 approximately 250 crop circles. However, those circles were more rugged than others, and many were already suspect. It is irrational to believe that all crop circles are fake for publicity or other reasons. Many crop circles appeared long before the phenomenon pained large recognition from the public and press. Too many circles and patterns are formed each year in too many countries for them to have been hoaxes. Many crop circles show strange mathematical trails when analyzed. The crop circle phenomenon is an enigma. Many dollars have been spent by researchers and their associations in an attempt to find a solution to this intriguing puzzle which will continue to haunt humanity until an explanation is found

User_SUN
- 澳大利亚，1973年12月。 2. 快速增长。
Gemini_AI
完全正确！👏
定位非常精准，直接找到了澳大利亚和1973年这个起点。
对数据的敏感度也很好，“快速增长”准确地概括了 112 -> 305 -> 1000 的变化趋势。
现在的雅思阅读中，除了考查细节定位（如第一题），也非常看重这种归纳总结能力。
我们要加快一点节奏了。让我们进入 **第三段 (Paragraph 3)**。
这一段主要描述麦田怪圈的演变以及与之相关的奇异现象。内容比较丰富，画面感很强。
📍 第三段原文 (Paragraph 3)
Nine out of ten circles remained simple with broken stems flattened to the ground and swirled. The stalks around the circles remained completely erect. But over the years, crop circles have become much more geometrically intricate. Patterns involved multiple circles, bars, triangles, rings and spurs. Pictorial imagery also appeared.

- 变化：几何结构更复杂，出现多圆圈、长条、三角形、环状、突出支线，还有具象图像。 2. 奇异现象：①视觉上见异常光线、怪圈上空奇异光晕；②听觉上闻不明声音、高音调颤音；③小型飞机飞越时电力突断。
Gemini_AI
回答得非常棒！👏
你的总结条理清晰，特别是对“奇异现象”的分类（视觉、听觉、电力），这种分类归纳的能力对于雅思阅读中的细节匹配题 (Matching Features) 非常有帮助。
接下来我们加快一点速度。因为第四段 (Paragraph 4) 比较短，主要是为了引出第五段 (Paragraph 5) 的具体研究发现，我们把这两段放在一起阅读。这两段的核心话题是 **“科学调查与发现” (Scientific Investigation & Findings)**。
📍 第四段 & 第五段原文 (Paragraphs 4 & 5)
(Para 4) Researchers have spent a great deal of time investigating different aspects of crop circles. They try to detect traces of human involvement in the circle making, test the area of the circle itself for geophysical anomalies, and analyze the field’s grain both from within and outside the circles, searching for differences.
(Para 5) Dr. W. C. Levengood of BLT Research in Cambridge, Massachusetts, has analyzed many grain samples and confirmed, time after time, significant changes at the cellular level of crop circle plants.

Gemini_AI
太棒了！🌟 你的答案非常准确，完全涵盖了文中的核心细节。
你对信息的提取能力很强，特别是对于并列信息的抓取（比如土壤中的多种异常），这在雅思填空题和简答题中是得分的关键。
现在，我们进入攻坚战的最后阶段：第六段 (Paragraph 6) 和 第七段 (Paragraph 7)。这一部分主要探讨了人们对麦田怪圈成因的解释 (Theories) 以及文章的**最终结论 (Conclusion)**。
📍 第六段 & 第七段原文 (Paragraphs 6 & 7)
(Para 6) Scientists have attempted to explain crop circles as a result of natural processes. One popular theory accepted by many mainstream scientists and academics is known as ‘Plasma Vortex Theory’. Developed by Dr. Terence Mearden, it theorizes that electrified air (plasma), on the side of hills, becomes mini-tornadoes and screws down onto the ground, creating the circles. The theory also holds that the electrified air would cause a light to appear above the circle and therefore account for UFO sightings.

Haunt /hɔːnt/: (v.) 困扰，萦绕在心头
💡 教授的中文阅读提示 (Guiding Questions)
这是雅思阅读中常见的“观点对立与驳斥”结构。请带着以下问题阅读，看看作者是如何权衡不同理论的：
关于自然成因（等离子旋涡理论）： 这个理论是如何一箭双雕的？即它试图同时解释哪两个现象？
关于人为成因（恶作剧理论）： 虽然有两个英国人承认造假，但作者用了哪些理由来反驳“所有怪圈都是人为的”这一观点？（请至少找出 2 个反驳理由）
关于最终结论： 在最后一段中，作者用哪个词（英文单词）来定性整个麦田怪圈现象？这说明问题解决了吗？
加油，这是最后一步了！完成这个我们就可以对整篇文章进行通关总结了。
第6轮对话迭代
User_SUN
- 两个现象：①麦田怪圈的形成；②UFO目击事件（怪圈上空出现光线）。 2. 反驳理由：①许多怪圈在现象受公众和媒体广泛关注前就已存在；②每年多国出现的怪圈数量和图案过多，不可能全是恶作剧；③许多怪圈经分析存在奇特数学轨迹。（任答2点） 3. 定性单词：enigma；问题未解决（仍需寻找合理解释）。
Gemini_AI
你的回答完全正确！🎉 看来你对最后这两段的理解非常透彻。
关于自然成因：你抓得很准，“等离子旋涡理论”确实是想一箭双雕，同时解释怪圈的形成和伴随的光线（UFO目击）。 🌪️🛸
关于反驳理由：你列举的理由非常有力。特别是“现象早于媒体炒作”和“全球数量庞大”这两点，逻辑上直接击破了“全是恶作剧”的说法。 🚫🤡
关于定性：Enigma（谜）这个词精准地概括了作者的态度——尽管有各种理论，但目前人类仍未找到确切答案。 ❓
恭喜你完成了整篇文章的逐段分析！ 👏
通过这样一段一段的拆解，我们不仅搞定了生词，还理清了文章的逻辑脉络。接下来，你想进行哪一步呢？
**全文总结 (Summary)**：试着用几句话把我们刚才分析的各段大意串起来，做一个英文摘要？（这是雅思写作和口语很好的练习）
**词汇巩固 (Vocabulary Review)**：我们把这篇阅读中出现的“雅思高频词”再集中过一遍？
**进入下一个任务 (Next Task)**：如果你觉得这篇已经掌握了，我们可以直接开始你计划中的 Task 2。
请告诉我你的选择！
