想要在 IELTS Writing Task 1 拿下高分，線圖 (Line Graph) 是你絕對要把握的基礎題型。這類題目主要考驗你「提取數據」、「描述趨勢」及「比較特徵」的能力。
掌握以下 4 個黃金步驟，讓你輕鬆寫出結構清晰、拿高分的專業好文！
💡 雅思寫作線圖解題 4 步曲
1. 📝 完美改寫題目 (Paraphrase)
改寫題目（Introduction）是第一步。運用替換詞彙將題目重新包裝，並精準點出圖表的主軸與時間範圍。
- 高分句型： The line graph illustrates / compares the changes in... over the period of [X] years.
2. 🌟 找出全貌與核心趨勢 (Overview)
這是 Task 1 拿 6 分與 7 分以上的關鍵分水嶺！不要急著寫具體數字，先用一至兩句話總結圖表中的最大趨勢（例如：整體上升、下降或波動）。
- 高分句型： Overall, it is clear that... witnessed an upward trend, while... experienced a significant decrease.
3. 📊 數據分組與細節描述 (Body Paragraphs)
將數據拆成 2 個段落（Body 1 & Body 2），著重於最高點、最低點以及關鍵交叉處。切記不要盲目羅列所有數字，而是要挑選具代表性的數據來佐證。
- 趨勢動詞： increase, decrease, fluctuate, stabilize
- 形容詞/副詞： significant / significantly, gradual / gradually, dramatic / dramatically
4. 🔤 活用必備高分字彙
想讓文章看起來更「學術」，替換掉單調的動詞是必要的。
- 📈 急劇上升： surge, soar
- 📉 顯著下降： plummet, drop
📖 實戰題目演練

The line graph compares the amount of electricity produced in France using four different sources of power over a period of 32 years.
It is clear that nuclear power was by far the most important means of electricity generation over the period shown. Renewables provided the lowest amount of electricity in each year.
In 1980, thermal power stations were the main source of electricity in France, generating around 120 terawatt hours of power. Nuclear and hydroelectric power stations produced just under 75 terawatt hours of electricity each, and renewables provided a negligible amount.
Just one year later, nuclear power overtook thermal power as the primary source of electricity. Between 1980 and 2005, electricity production from nuclear power rose dramatically to a peak of 430 terawatt hours.
By contrast, the figure for thermal power fell to only 50 terawatt hours in 1985, and remained at this level for the rest of the period. Hydroelectric power generation remained relatively stable, at between 50 and 80 terawatt hours, for the whole 32-year period, but renewable electricity production saw only a small rise to approximately 25 terawatt hours by 2012.
🔑 範文亮點單字與片語 (Collocations)
- Means of electricity generation: 發電方式
- Negligible amount: 微不足道的數量
- Overtook: 超越（描述數據交叉必備）
- Rose dramatically to a peak of...: 急劇上升至...的頂峰
- Remained relatively stable: 保持相對穩定
