Sample IELTS Writing Task 1 Question and Model Answer
Let’s select the first question and create a sample answer:
The graph below shows the average Air Quality Index (AQI) in four major cities from 2010 to 2023.
(Insert a line graph here depicting the AQI trends in four cities – London, Beijing, New Delhi, and New York City – from 2010 to 2023. Show some cities improving their AQI over time, while others experience fluctuations or worsening conditions).
Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
Model Answer:
The line graph provides a comparative analysis of the average Air Quality Index (AQI) in four major cities – London, Beijing, New Delhi, and New York City – spanning from 2010 to 2023.
Overall, London and New York City demonstrate a consistent downward trend in AQI, indicating improving air quality. Conversely, Beijing and New Delhi show fluctuating patterns, with the former experiencing a slight improvement in recent years and the latter exhibiting a concerning upward trend, suggesting deteriorating air quality.
In 2010, Beijing had the poorest air quality with an AQI of 90, followed by New Delhi at 80. London and New York City started at a much lower AQI of 50 and 45, respectively. Over the 13-year period, London and New York City have successfully reduced their AQI to approximately 35 and 30, respectively.
Beijing’s AQI fluctuated considerably, reaching a peak of 100 in 2015 before declining to around 70 in 2023. New Delhi, despite some fluctuations, showed a worrying increase in AQI, reaching a concerning level of 95 by 2023.
