在雅思写作考试中，Task 1的小作文部分要求考生根据图表、表格或流程图等信息进行描述和分析，数据回落（Decline或Drop）是常见的变化趋势之一，许多考生在面对这类数据时，容易陷入重复用词或表达单一的困境，如何准确、多样地描述回落趋势，同时保持语言的自然流畅，是提升小作文分数的关键。
描述数据回落时，考生需要掌握多种动词、名词和短语，避免重复，以下是一些高频且地道的表达方式：
-
动词类
- 下降：decline, decrease, drop, fall, dip, diminish, reduce
- 急剧下降：plunge, plummet, slump, nosedive
- 缓慢下降：dwindle, taper off, ease off
例句：
- The number of visitors plummeted from 500 to 200 in just three months.
- After reaching a peak in 2010, the figures tapered off gradually.
-
名词类
- 下降：decline, decrease, drop, fall, reduction
- 急剧下降：plunge, slump, crash
- 持续下降：downward trend, steady decline
例句：

- The data shows a consistent downward trend over the decade.
-
短语类
- 经历下降：experience a decline, witness a drop
- 降至最低点：hit a low, reach the bottom
- 从...下降到...：fall from...to..., drop by...
例句：
- The unemployment rate hit a low of 3% in 2020.
- Oil prices dropped by 15% compared to the previous year.
描述回落趋势的进阶技巧
单纯罗列数据变化是不够的，高分作文需要结合原因分析、对比和细节补充，使描述更具逻辑性和深度。
-
结合原因分析
在描述回落时，适当加入可能的原因能让文章更充实。例句：
- The sharp decline in car sales could be attributed to the rising fuel prices.
- The gradual decrease in newspaper readership might result from the popularity of digital media.
-
使用对比手法
通过对比峰值与低谷，或不同时间段的回落速度，使描述更生动。例句：
- While the figures peaked at 800 in 2015, they plunged to just 300 by 2020.
- The decline was more pronounced in urban areas compared to rural regions.
-
强调幅度与速度
用副词或形容词突出回落的速度和程度，增强表达效果。例句：
- The stock market dramatically crashed within a week.
- A slight dip was observed in the final quarter.
避免常见错误
许多考生在描述回落时容易犯以下错误，影响得分：
-
重复使用同一词汇
例如连续使用“decrease”或“drop”，显得单调，解决方法是灵活替换同义词，如用“diminish”“dwindle”等。 -
忽略数据具体值
只写“下降”，却不提具体数字或百分比，雅思评分标准要求准确引用数据，因此务必写明变化幅度。错误示例：The population decreased.
正确示例：The population decreased by 10%, from 1 million to 900,000. -
过度主观推测
小作文重在客观描述，除非题目明确要求分析原因，否则避免过多主观猜测。
高分范文示例
以下是一段描述回落趋势的范文，供参考：
The graph illustrates changes in the market share of three smartphone brands between 2010 and 2020. Brand A initially dominated the market, peaking at 45% in 2015. However, its share plummeted to just 20% by 2020, likely due to fierce competition from emerging brands. In contrast, Brand B experienced a steady decline, dropping from 30% to 15% over the decade. The most dramatic slump occurred in Brand C, which nosedived from 25% to a mere 5% after 2018, possibly because of technological obsolescence.
这段描述结合了数据变化、原因分析和对比，语言多样且逻辑清晰。
