      {"q": "1. 在雅思听力中，'approximately' 最可能被替换为以下哪个词？", "type": "choice", "answer": "C. roughly", "explanation": "approximately = roughly/about/around，都是'大约'的意思。A选项exactly是反义，B选项slightly是'轻微地'，D选项rapidly是'快速地'。"},
      {"q": "2. 题干中出现 'initial impression'，录音中可能听到什么？", "type": "choice", "answer": "B. first reaction", "explanation": "initial = first, impression = reaction/thought/feeling。A选项last memory是反义，C选项final decision也是反义，D选项middle stage不对应。"},

    "topic": "The chart below shows the percentage of households with internet access in three European countries from 2005 to 2020.",
    "modelAnswer": "The line graph illustrates the proportion of households with internet access in Germany, France, and Spain over a 15-year period from 2005 to 2020.\n\nOverall, all three countries experienced a significant increase in internet penetration, with Germany consistently maintaining the highest rate throughout the period.\n\nIn 2005, Germany led with approximately 65% of households having internet access, followed by France at 50% and Spain at just 35%. Over the next decade, all three countries saw steady growth, though at different rates. Germany reached 85% by 2015, while France climbed to 75% and Spain to 65%.\n\nThe most dramatic growth occurred in Spain, which more than doubled its figure from 35% in 2005 to nearly 88% by 2020, almost catching up with Germany. By the end of the period, Germany had reached 92%, France 85%, and Spain 88%, meaning the gap between the three countries had narrowed considerably compared to 2005.\n\nNotably, the rate of increase was fastest between 2010 and 2015 for all three countries, after which the growth began to level off, particularly in Germany and France.\n\n(Word count: 178)\n\n【范文解析】\n1. 结构：Introduction → Overview → Body paragraphs (按时间/国家分组) \n2. 重点词汇：illustrates, proportion, penetration, consistently, steady growth, dramatic growth, narrowed, level off\n3. 数据描述多样化：led with, followed by, climbed to, reached, more than doubled, almost catching up with\n4.
