Task Achievement / Task Response — Band 7.5

这篇文章涵盖了任务的所有要求。你成功地识别了主要趋势，并提供了数据来支持你的观点。概述部分清晰，突出了关键特征，例如收入最高和最低的类别。然而，你的分析中存在一个小错误：你提到 $75,000–$99,999 这一类别在整个期间一直保持最低，但数据显示 $50,000–$74,999 这一类别在 2007 年和 2011 年实际上更低。尽管如此，整体报告准确且结构良好，对所给图表进行了清晰的总结。

Coherence and Cohesion — Band 7.5

文章逻辑组织严密，包含清晰的引言、概述以及有效归纳数据的正文段落。你使用了 'Additionally,' 'In 2007,' 和 'As for' 等衔接词来引导读者理解信息。观点推进流畅，分段也十分恰当。为了达到更高的分数，请确保指代始终精确；例如，概述与正文段落之间的过渡可以更加自然，以提升信息流的连贯性。

Lexical Resource — Band 7.0

你展示了足够的词汇量来清晰地传达信息。诸如 'experienced an upward trend,' 'remained stable,' 和 'fluctuated slightly' 等短语在描述数据时使用得非常有效。文中对 'number' 和 'households' 一词的使用略显重复，这限制了词汇的多样性。为了改进，尝试加入更多的同义词或替代表达来指代数据点，例如 'the proportion of families' 或 'the count of households.' 词汇总体准确，符合学术任务的要求。

Grammatical Range and Accuracy — Band 7.0

文章使用了简单句和复杂句的组合。虽然大多数句子表达清晰，但仍存在一些语法疏漏。例如，'The trend of the number of households who earned $25000-$49999 was similar to the changes in less than $25000' 表达略显生硬，而 'In terms of the figures for households who earned over $100000 was the largest' 包含语法错误（主语 'figures' 与谓语动词 'was' 不一致）。尽管存在这些错误，但文章含义始终明确，标点符号的使用也基本得当。
