折线图的核心特征

折线图通常以时间为横轴,数值为纵轴,通过线条的起伏变化呈现数据趋势,在雅思考试中,常见主题包括人口变化、商品销量、温度波动等,这类图表的核心考察点在于:

  1. 趋势描述:上升(increase/rise)、下降(decline/drop)、波动(fluctuate)、稳定(remain stable)等;
  2. 数据对比:不同线条之间的数值差异或趋势差异;
  3. 关键节点:最高点(peak)、最低点(lowest point)、交叉点(intersection)等。

一道经典题目可能展示1990-2020年三个国家汽车销量的变化,考生需要同时描述各国趋势,并分析其相互关系。

四段式结构解析

引言段(Introduction)

用1-2句话改写题目,避免直接复制题干。

The line graph illustrates changes in car sales volumes across three countries (A, B, C) between 1990 and 2020.

概述段(Overview)

概括图表最显著的特征,不涉及具体数据,建议包含:

  • 整体趋势(如总体增长/下降)
  • 关键差异(如某国始终领先)
  • 异常现象(如某年突然波动)

示例:

Overall, while Country A maintained dominance throughout the period, Country C exhibited the most dramatic growth, surpassing Country B after 2010.

细节段(Details Paragraph 1 & 2)

分段描述具体数据,建议按以下逻辑组织:

  • 时间顺序:早期→中期→后期
  • 数值分组:先写高数值线条,再写低数值
  • 对比关系:用while/whereas连接对比信息

数据描述需注意:

  • 搭配准确介词:at 100 units, to 150 units, by 50%
  • 使用多样化表达:
    • 上升:climb steadily / experience a surge
    • 下降:plummet sharply / undergo a gradual decline

高分语言技巧

趋势动词+副词组合

避免重复使用"increase/decrease",可替换为:

  • 剧烈变化:soar, rocket, plunge, collapse
  • 平缓变化:creep up, edge down, level off

数据引用方式

  • 精确数据:reached a peak of 200 units (2015)
  • 约数表达:approximately 150 / roughly three-quarters

复杂句型应用

  • 分词结构:Starting at 50 units, the figure doubled by 2000.
  • 定语从句:Country B, which ranked first initially, was overtaken in 2010.

常见错误规避

  1. 机械罗列数据:应筛选代表性数据,如首尾年、极值点;
  2. 时态混乱:过去时间用一般过去时,预测数据用将来时;
  3. 单位遗漏:始终标注单位(thousands, %, °C等);
  4. 主观推测:避免分析原因,仅陈述图表信息。

实战范文示例

The graph below shows electricity production from different sources in a country from 1990 to 2020.

Introduction
The line graph compares four energy sources (coal, natural gas, nuclear, and renewables) in terms of electricity generation capacity over a 30-year period.

Overview
While coal remained the primary energy source despite fluctuations, renewables demonstrated the steepest upward trajectory. Nuclear power showed minimal change after an initial rise.

Details
In 1990, coal accounted for 150 terawatt-hours (TWh), far exceeding natural gas at 40 TWh. Over the next decade, coal usage dipped to 120 TWh but rebounded to 180 TWh by 2010. In contrast, renewables began at merely 10 TWh, yet climbed exponentially to 90 TWh in the final year.

Natural gas followed a moderate growth pattern, rising from 40 TWh to 70 TWh with intermittent drops. Nuclear energy plateaued at around 60 TWh after reaching this level in 2000, showing no significant variation thereafter.
