IELTS Academic Writing Task 1: A Complete Guide to High Scores on Chart Questions | 雅思小作文写作攻略：图表题高分技巧

📚 IELTS Academic Writing Task 1: A Complete Guide to High Scores on Chart Questions | 雅思小作文写作攻略：图表题高分技巧

The first writing task in the IELTS Academic exam requires you to summarise visual information in at least 150 words within 20 minutes. Many candidates lose marks not because they lack English ability, but because they do not know how to structure a clear, focused report. This guide breaks down every step needed to write a high-scoring answer for chart-based questions.

雅思学术类写作第一项任务要求你在20分钟内用至少150个单词概括图表信息。许多考生丢分并不是因为英语能力不足，而是不懂得如何组织一篇清晰、有针对性的报告。本指南将逐步拆解图表题拿到高分的所有关键步骤。

1. Understanding the Task and Marking Criteria | 理解任务与评分标准

Task 1 is a purely factual report. You must never give your personal opinion, speculate about reasons, or suggest solutions. The examiner wants to see whether you can identify the main features of a chart, compare data meaningfully, and use accurate vocabulary and grammar.

任务1是一篇纯事实性报告。你绝不能发表个人观点、推测原因或提出解决方案。考官希望看到你能否识别图表的主要特征、有意义地比较数据，并使用准确的词汇和语法。

Your answer is marked on four criteria:

Task Achievement: Did you answer the question fully and give a clear overview?

任务完成情况：你是否完整回答了题目，并提供了清晰的概述？
Coherence and Cohesion: Is the information logically ordered and well-linked?

连贯与衔接：信息是否逻辑有序、衔接自然？
Lexical Resource: Do you use a wide range of words appropriately?

词汇资源：你是否恰当且多样地使用词汇？
Grammatical Range and Accuracy: Do you use varied sentence structures without many errors?

语法多样性与准确性：你是否使用多样的句式，且错误较少？

Remember that the overview, which will be discussed later, is the single most important part of your report for a high Task Achievement score.

请记住，稍后我们会详细讨论的“概述”部分是整篇报告中决定任务完成情况得分的最关键部分。

2. Paraphrasing the Question Prompt | 改写题目要求

You should never copy the question prompt word by word. The first sentence of your report must be a paraphrase. This demonstrates lexical resource and immediately shows the examiner your skills.

你绝不能一字不差地照抄题目。报告的第一句必须是改写句。这能展示你的词汇能力，并立刻向考官证明你的水平。

For example, if the original prompt says “The chart shows the percentage of households in the UK with internet access from 2005 to 2015,” you could write “The line graph illustrates how the proportion of British households connected to the internet changed between 2005 and 2015.” Notice how “percentage” becomes “proportion”, “UK” becomes “British”, and “shows” becomes “illustrates”.

例如，如果原题写的是“The chart shows the percentage of households in the UK with internet access from 2005 to 2015”，你可以改写为“The line graph illustrates how the proportion of British households connected to the internet changed between 2005 and 2015”。请注意，“percentage”改成了“proportion”，“UK”改成了“British”，“shows”改成了“illustrates”。

Useful paraphrase verbs include “illustrate”, “compare”, “present”, “summarise”, “indicate”, and “provide information about”. Also change the chart type if you know its exact name: from “chart” to “bar chart”, “pie chart”, “line graph”, or “table”.

常用的改写动词包括“illustrate”、“compare”、“present”、“summarise”、“indicate”以及“provide information about”。同时，如果你知道图表的具体类型，也可以将笼统的“chart”换成“bar chart”、“pie chart”、“line graph”或“table”。

3. Structuring Your Report | 构建报告结构

A high-scoring report always has four parts: an introduction, an overview, and two or three paragraphs of detailed information. This structure keeps your answer coherent and easy to follow.

高分报告通常包含四个部分：引言、概述，以及两到三段细节描述。这种结构能让你的回答连贯且易于阅读。

Introduction → Overview → Details 1 → Details 2

The introduction is one sentence that paraphrases the prompt. The overview is a paragraph summarising the most striking trends or main changes without giving exact numbers. Then you need two separate detail sections: each one describes a clear group of data with precise figures.

引言是用一个句子改写题目。概述段落总结最显著的趋势或主要变化，不给出具体数字。然后你需要两个独立的细节段落，每段描述一组明确的数据并给出准确数字。

Do not place the overview at the end. IELTS examiners expect to see it either at the end of the first paragraph or as the second paragraph. Putting it after the introduction is safer and easier to mark.

不要把概述放在末尾。雅思考官希望看到概述出现在第一段末尾或第二段。把它放在引言之后更稳妥，也更容易被评分。

4. Choosing and Grouping Key Data | 选择与归纳关键数据

You do not need to describe every value in the chart. In fact, doing so will lower your Task Achievement score because you will fail to highlight the main features. Instead, look for the highest and lowest points, the largest increases or decreases, periods of stability, and exceptions to a general trend.

你不需要描述图表中的每一个数值。事实上，这样做会降低任务完成情况的得分，因为你就无法突出主要特征。相反，你应当寻找最高点和最低点、最大幅度的上升或下降、稳定期，以及总体趋势中的例外情况。

After identifying the key features, group them logically. You might group by time period, by category, by similar movement, or by comparing one group against another. For example, in a chart about three countries, you could put two countries in one paragraph because they show similar patterns, and the third country in another paragraph because it behaves differently.

找到关键特征后，要对其进行逻辑分组。你可以按时间段、类别、相似变化趋势，或一个组与另一个组比较来划分。例如，在一张展示三个国家的图表中，你可以将两个趋势相似的国家放在同一段，把另一个走势不同的国家放在另一段。

A common question is: how many numbers should you include? A good rule is to include around 8 to 12 values for a 150-word report. Quality matters more than quantity.

常见的问题是：应该写多少个数字？一个好规则是，150词左右的报告大约包含8到12个数值。质量比数量更重要。

5. Describing Trends with Precise Vocabulary | 用精确词汇描述趋势

IELTS examiners award high Lexical Resource scores to candidates who avoid repeating the same words. You must develop a wide toolbox of verbs, nouns, adverbs, and adjectives for describing movement.

雅思考官会给那些避免重复使用相同词汇的考生更高的词汇资源分。你需要积累大量描述变化的动词、名词、副词和形容词。

Direction	Verbs (past tense)	Nouns / Phrases
Upward	rose, increased, grew, climbed, surged	an increase, a rise, a growth, a surge
Downward	fell, declined, decreased, dropped, sank, dipped	a decrease, a decline, a fall, a drop
No change	remained stable, stayed constant, levelled off	stability, a plateau, no change
Fluctuation	fluctuated, varied, oscillated	a fluctuation, variation, ups and downs
Peak / Bottom	peaked at, reached a peak, hit the lowest point, bottomed out	a peak of, a low point of, a bottom

You also need adverbs and adjectives to describe speed and size of change. For large changes use “dramatically”, “significantly”, “substantially”, “sharply”. For small changes use “slightly”, “gradually”, “moderately”, “marginally”. For example: “The number of tourists rose sharply in 2010 but then declined gradually.”

你还需要副词和形容词来描述变化的速度和幅度。大幅度变化可以用“dramatically”、“significantly”、“substantially”、“sharply”；小幅度变化用“slightly”、“gradually”、“moderately”、“marginally”。例如：“游客数量在2010年急剧上升，之后逐渐下降。”

6. Making Comparisons Effectively | 有效进行比较

Task 1 chart questions always require comparison. You cannot simply list numbers in a sequence. Instead, you need explicit comparative language to show the relationship between categories or periods.

任务1图表题总是要求进行比较。你不能只是按顺序罗列数字，而需要使用明确的比较语言来显示不同类别或时期之间的关系。

Useful structures include:

“A was twice as high as B.”

“A是B的两倍高。”
“The number of X was three times greater than that of Y.”

“X的数量是Y的三倍还多。”
“While A increased steadily, B remained almost unchanged.”

“A稳步上升，而B几乎保持不变。”
“Compared with 2000, the figure for 2015 was significantly higher.”

“与2000年相比，2015年的数字明显更高。”

Words like “whereas”, “while”, “however”, “in contrast”, “by comparison”, and “similarly” are essential for showing logical relationships. Avoid placing all comparative sentences together; spread them throughout your detail paragraphs.

“whereas”、“while”、“however”、“in contrast”、“by comparison”和“similarly”这类词对于显示逻辑关系至关重要。不要把比较句全部堆在一起，而应把它们分散到各个细节段落中。

7. Handling Numbers and Data Points | 处理数字与数据点

Numbers are central to Task 1, but they should be used accurately and naturally. Use percentages, fractions, and approximations to avoid robotic repetition.

数字是任务1的核心，但使用时要准确、自然。可以使用百分比、分数和约数来避免机械重复。

Instead of writing “25%, 30%, 35%, 40%”, you could say “roughly a quarter, nearly a third, just over one-third, and two-fifths.” This variety is impressive and more academic.

与其写“25%、30%、35%、40%”，不如说“roughly a quarter（大约四分之一）、nearly a third（接近三分之一）、just over one-third（略多于三分之一）以及two-fifths（五分之二）”。这种变化令人印象深刻，也更学术。

When citing exact numbers, always include units: “£m”, “tonnes”, “kilometres”, “%”, “million”. For example, “Oil production peaked at 4.5 million barrels per day in 2008.”

引用具体数字时，一定要包括单位：“£m”、“tonnes”、“kilometres”、“%”、“million”。例如：“石油产量在2008年达到每天450万桶的峰值。”

Also be careful with approximate expressions: “approximately”, “around”, “about”, “just over”, “just under”, “nearly”, “roughly”. Using these helps you avoid inaccurate readings when the chart is not perfectly precise.

同时要注意约数表达：“approximately”、“around”、“about”、“just over”、“just under”、“nearly”、“roughly”。当图表不够精确时，使用这些词可以避免读图不准确的问题。

8. Using Grammar to Boost Your Score | 用语法提升分数

Grammatical Range and Accuracy counts for 25% of your Task 1 score. A simple string of short sentences will not earn a high mark. You need to combine structures such as comparatives, passive voice, and time clauses.

语法多样性与准确性占任务1分数的25%。一连串简单短句无法获得高分。你需要结合比较级、被动语态和时间状语从句等结构。

Use the correct tense for the timeframe. If the data is in the past, use the past simple: “Sales increased.” If there is a projection into the future, use “is expected to” or “will”. If the chart shows a general pattern without dates, use the present simple.

要根据时间范围使用正确的时态。如果数据是过去的，用一般过去时：“Sales increased.” 如果涉及未来预测，用“is expected to”或“will”。如果图表没有日期、只显示一般规律，用一般现在时。

Combine clauses to create complex sentences. For example: “Although the number of cars rose steadily in urban areas, it fell sharply in rural regions.” This one sentence uses an adverb clause and a contrast, giving you much more credit than two separate sentences.

要组合从句来创建复杂句。例如：“Although the number of cars rose steadily in urban areas, it fell sharply in rural regions.” 这一句既使用让步状语从句又包含对比，比写成两个独立句子得分高得多。

Passive structures are also valuable: “A significant increase was observed in the first decade.” Use them to vary your sentence openings and maintain an academic tone.

被动结构也很有价值：“A significant increase was observed in the first decade.” 使用被动结构可以让句首更有变化，并保持学术语气。

9. Common Mistakes to Avoid | 避免常见错误

Many candidates make the same predictable mistakes. By recognising them now, you can make instant improvements to your writing.

许多考生都会犯一些常见的可预测错误。现在识别它们，你就能立刻改进自己的写作。

Copying the prompt: This wastes words and shows no vocabulary skill. Always paraphrase.

照抄题目：这会浪费字数，也无法展示词汇能力。一定要改写。
No overview: Without an overview, your Task Achievement score cannot rise above Band 5.

缺少概述：没有概述，任务完成情况的得分不可能超过5分。
Describing every single data point: Selecting key features is a core skill. Avoid data dumping.

描述每一个数据点：选择关键特征是一项核心技能。避免数据堆砌。
Using personal opinions: Never write “I believe”, “in my opinion”, or “it would be better if”.

加入个人观点：绝不写“I believe”、“in my opinion”或“it would be better if”。
Wrong tense: Check whether your chart refers to past years, future predictions, or no time at all.

时态错误：检查你的图表是过去的年份、未来的预测，还是没有时间。
Informal language: Avoid contractions like “don’t” and vague words like “big”, “things”. Use academic alternatives.

非正式语言：避免“don’t”这类缩写，避免“big”、“things”等模糊词。使用学术替代词。
Writing fewer than 150 words: You may be penalised for underlength, so count your words.

字数少于150词：作文字数不足可能会被扣分，所以一定要数一下。

10. Sample Answer Analysis | 范文分析

Let us examine a short sample question and a model answer to see how the principles above work in practice.

让我们看一个简短的例题和范文，了解上述原则在实践中如何运用。

Prompt: “The line graph shows the number of airline passengers flying from London to Paris and from Berlin to Rome between 2000 and 2015.”

题目：“折线图显示了2000年至2015年间从伦敦飞往巴黎以及从柏林飞往罗马的航空旅客数量。”

Model answer: “The line graph illustrates how many passengers flew between two pairs of European cities from 2000 to 2015. Overall, the London-Paris route remained the busier route throughout the entire period, and both routes showed an upward trend, although London-Paris experienced substantial fluctuations. The number on the London-Paris route started at 3 million, rose gradually to 4 million by 2007, then surged to 5.5 million in 2010. After a sharp drop to 4.2 million in 2012, it recovered to a final figure of 5 million. By contrast, Berlin-Rome grew steadily from 1 million to 2.5 million without any major fluctuations, before levelling off in the final three years.”

范文：“这张折线图显示了2000年至2015年间在两个欧洲城市对之间飞行的乘客数量。总体而言，伦敦-巴黎航线在整个期间一直是更繁忙的航线，两条航线都呈现上升趋势，不过伦敦-巴黎航线经历了明显波动。伦敦-巴黎航线的乘客数量从300万开始，到2007年逐步上升到400万，随后在2010年飙升至550万。在2012年急剧下降到420万之后，又回升至最终500万。相比之下，柏林-罗马航线从100万稳步增长到250万，没有任何大的波动，最后三年趋于平稳。”

This answer scores well because it begins with a clear paraphrase, gives an overview with two main trends, uses precise trend verbs such as “surged” and “levelled off”, and compares the two routes explicitly. Numbers are selected, not listed exhaustively, and the grammar uses a mix of simple past and contrasting clauses.

这篇范文得分高，因为它以清晰的改写开头，提供了包含两大趋势的概述，使用了“surged”和“levelled off”等精确的趋势动词，并明确比较了两条航线。数字是被选择性使用的，而不是穷举罗列；语法上混合使用一般过去时和对比从句。

11. Final Checklist and Practice Tips | 最终自查清单与练习建议

Before the exam, build a mental checklist so that your writing process becomes automatic. In the first two minutes, read the chart carefully, identify the timeframe, units, and key features. Then write your introduction and overview before moving to details.

考试前，建立一份心理检查清单，让你的写作过程变得自动化。前两分钟仔细读图，确认时间范围、单位和关键特征。然后先写引言和概述，再进入细节描述。

Use this checklist before you finish:

Have I paraphrased the prompt clearly?

我是否清楚改写了题目？
Is there a clear overview without numbers?

是否有清晰且不含数字的概述？
Are the details grouped logically?

细节部分是否按逻辑分组？
Did I use a variety of trend vocabulary?

我是否使用了多样的趋势词汇？
Did I compare data at least three times?

我是否至少进行了三次数据比较？
Is the tense correct for the timeframe?

时态是否符合时间范围？
Are there at least 150 words?

字数是否达到至少150词？

For practice, choose one chart type each day and write a full report. Time yourself at 20 minutes. Then spend 10 minutes analysing your own writing against the four marking criteria. This skill of self-correction is what separates Band 6 answers from Band 8 answers.

练习时，每天选择一种图表类型并完成一篇完整报告，用20分钟计时。然后花10分钟对照四项评分标准分析自己的文章。这种自我纠错能力正是6分答案和8分答案之间的差距所在。

Finally, study official IELTS sample answer scripts. Notice how they organise information and transition between sentences. Over time, these patterns will become natural to you, and your Task 1 score will rise steadily.

最后，研究雅思官方范文，注意它们如何组织信息、如何在句子之间过渡。随着时间推移，这些模式会变成你的自然反应，任务1的分数也会稳步提高。
