Describing data: the language that Task 1 is really testing.
Academic Writing Task 1 gives you a chart and one job: describe what it shows, accurately and in formal English. The ideas are handed to you; the marks are in the language of change. Say rose sharply where you meant went up a lot, and the same figure reads a band higher.
Why this matters. In Task 1 you are not asked to think, only to report, so the content is already on the page. The band comes almost entirely from Lexical Resource and Grammatical Range: whether you can vary the verbs of movement (rise / climb / surge), pin a trend to the right adverb (sharply / steadily / gradually), and compare figures precisely (twice as many, a third of, overtook). Get this language automatic and Task 1 becomes the easiest four marks in the test.
Four families that cover every chart.
You do not need a glossary. You need a handful of accurate collocations in each of these areas, ready to deploy.
Going up
rise · climb · increase · surge / soar
The commonest movement; keep a range ready and reserve surge, soar, rocket for steep rises.
Car ownership rose sharply between 2000 and 2010.
Going down
fall · decline · drop · plummet / plunge
The mirror set; keep it formal and avoid “went down”. Save plummet, plunge for sharp falls.
Sales fell gradually over the second half of the year.
Steady & unsteady
remain stable · level off · plateau · fluctuate
What a line does when it is not simply rising or falling, stability, or irregular movement.
Prices fluctuated before levelling off in 2015.
Peaks, troughs & comparison
peak at · reach / stand at · overtake · the gap between
Fixing points and comparing series, where most Band 7+ language lives.
Demand peaked at 40% before falling back.
Precision beats rarity
A movement verb on its own is Band 6; the lift is the adverb that pins how fast or how far. Pair every verb of change with an adverb of degree, rose sharply, fell steadily, increased gradually, dipped slightly, and you are writing at Band 7 by default. A naked verb (“it increased”) leaves marks on the table. The verb carries the adverb.
The same point, from Band 6 to Band 8.
At Band 5
“The number go up and down a lot and then it is high.” Movement is described with go up / down, repeated, often with a tense or agreement slip, and no figures are fixed to the trend.
At Band 6
“The figure increased and then decreased before it went up again.” Correct but plain, the verbs carry no adverbs and the sentence lists rather than describes.
At Band 7
“The figure rose steadily to 2010, dipped briefly, then climbed to a peak of 60%.” Varied verbs, adverbs of degree, and a fixed peak.
At Band 8+
“Having risen steadily to 2010, the figure dipped briefly before climbing to a peak of roughly 60%, the highest point on the chart.” Precise lexis, a participle clause, approximation, and a comparison.
The upgrade most worth making.
Each swap takes a vague, everyday phrase and replaces it with the collocation an examiner expects on this topic. Use them where they fit naturally, not all at once.
| Instead of… | Use… | For example |
|---|---|---|
| went up a lot | rose sharply / increased significantly | Exports rose sharply after 2005. |
| went down | fell / declined | Membership declined after 2010. |
| stayed the same | remained stable / levelled off | Prices remained stable for a decade. |
| went up and down | fluctuated | The rate fluctuated throughout the period. |
| the most | peaked / the highest | Output peaked in June. |
| got to | reached / stood at | Sales reached 5 million. |
| a big difference | a marked / substantial difference | There was a marked difference between the two. |
| about (a third) | approximately / roughly | Roughly a third chose cycling. |
Two cautions. Task 1 reports data and gives no opinion, do not write “I think” or invent reasons the chart does not show. And do not over-decorate: one precise verb plus one adverb beats three synonyms piled up. To use this language on a real chart, try an interactive Writing Task 1 paper →

Choose the more precise, topic-appropriate option for each gap. Press Check answers for your score and the reason behind each one. Nothing is sent anywhere.
You can collect topic words. Using the right one, accurately, under timed pressure is the work.
Memorised “big” words used wrongly cost marks; precise collocations used naturally earn them, and the difference is hard to judge in your own writing.
In a lesson I mark your topic vocabulary the way an examiner does, where a collocation is exactly right, where it is forced, and where a plain word would have been stronger. Lessons are £20 for fifty minutes, one to one, in proper British English; the first step is a free 25-minute introduction.
