在雅思写作考试中，小作文（Task 1）通常要求考生描述图表、表格或流程图中的数据变化趋势。表示数据持平的情况是常见考点之一，许多考生在面对数据无明显波动时，容易陷入词汇匮乏或句式单一的困境，本文将详细介绍如何在雅思小作文中精准表达持平趋势，并提供实用句型与高分范例，帮助考生提升写作表现。

什么是数据持平？

数据持平指的是某一时间段内数值保持稳定，没有显著上升或下降，在折线图、柱状图或表格中，如果某组数据的变化幅度极小，甚至完全水平，就需要用恰当的语言描述这一现象。

• 某产品销量在2020年至2022年保持稳定
• 两个国家的失业率在五年内几乎相同

表达持平的核心词汇

• stay constant（保持不变）

• level off（趋于平稳）

高分句型与结构

基本描述句型

比较句型（用于两组数据持平）

时间状语的使用

• from [year] to [year]（从某年到某年）
  • The birth rate remained steady from 2000 to 2010.

常见错误与修正

错误1：过度使用“the same”

• 原句：The sales were the same in 2019 and 2020.
• 优化：The sales figures remained unchanged between 2019 and 2020.

错误2：忽略数据细节

• 原句：The graph was flat.
• 优化：The graph showed a stable trend, with no fluctuations between 2015 and 2020.

错误3：混淆“stable”与“stagnant”

• “Stable”是中性词，表示稳定；“stagnant”可能带有负面含义（如经济停滞）。
• 正确用法：The market remained stable（而非stagnant）during the recession.

实战范例分析

范例1（折线图描述） ** 某城市2000-2020年人口变化

描述：
From 2000 to 2010, the population of the city experienced a gradual increase, rising from 1.5 million to 2 million. However, between 2010 and 2020, the figures levelled off, remaining stable at approximately 2 million. This suggests that the growth rate reached a plateau in the last decade.

范例2（表格数据） ** 两种能源的使用比例（2015-2025）

描述：
While the use of solar power rose significantly from 10% to 25%, coal consumption showed little variation, staying constant at around 40% throughout the period. This indicates a consistent reliance on traditional energy sources despite the growth of renewables.

个人观点

在雅思小作文中，描述持平趋势并非简单地重复“没有变化”，而是需要通过多样化的词汇和句型展现语言能力，建议考生在备考时整理专属的表达库，并多练习图表分析，确保在考场上能快速准确地捕捉数据特征，稳定的数据往往反映重要背景信息,合理描述能为文章增色不少。
