Sample Task 1 Report
The table details the proportions of fruit and vegetable purchases made using four distinct units of measurement in one city between 2005 and 2025.
Overall, it is clear that kilograms became the dominant unit by the end of the period, after experiencing a steady upward trend, while the use of pounds and traditional containers fell significantly.
In 2005, pounds were the most common measurement, accounting for 44% of purchases, followed by kilograms at 30%. In sharp contrast, baskets and bags stood at 18%, while pieces represented just 8%.
Over the subsequent two decades, kilograms more than doubled to reach 64% in 2025, becoming the primary choice for shoppers. Conversely, the proportion of shoppers using pounds more than halved to 16%. Similarly, baskets and bags dropped to 8%. By comparison, buying by individual pieces saw a slight increase, rising to 12% in 2025. Overall, metric measurement gained widespread adoption as older units declined.
Why This Works: Key Phrase Notes
Review why these 8 highlighted expressions improve clarity, precision, and tone in Task 1 writing.
Why this works: Signals the start of your main overview statement immediately. IELTS markers require a visible summary of key trends, and this phrase introduces it smoothly.
Why this works: Combines an adjective and noun to describe continuous growth (30% to 46% to 64%) over time without repeating basic words like "went up".
Why this works: Connects a category to its exact percentage or quantity naturally. It prevents repetitive sentence structures like "the figure was 44%".
Why this works: Ranks items in order of size (44% then 30%) in a simple, clear way, without repeating "the figure was".
Why this works: Clearly highlights a large difference between higher figures (44% and 30%) and lower figures (18% and 8%), making your comparisons sharper.
Why this works: Accurately describes a rise from 30% to 64% (since exactly 2x is 60%). Adding "more than" shows careful data analysis.
Why this works: Links two opposite trends smoothly (kilograms went up while pounds went down), improving paragraph flow and cohesion scores.
Why this works: Accurately describes a fall from 44% to 16% (since half is 22%, and 16% is below half). It demonstrates strong vocabulary range.
