Understanding the Task
Example IELTS Writing Task 1 Prompt:
You should spend about 20 minutes on this task.
The charts below show the levels of air pollution in different regions from 2000 to 2023. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
Sample Data Illustration:
(Below is a hypothetical chart for demonstration; in an actual IELTS exam, charts would be provided.)
| Year | North America | Europe | Asia |
|------|---------------|--------|------|
| 2000 | 250 | 300 | 400 |
| 2005 | 240 | 290 | 420 |
| 2010 | 230 | 280 | 440 |
| 2015 | 220 | 270 | 460 |
| 2020 | 210 | 260 | 480 |
| 2023 | 200 | 250 | 500 |
Analyzing the Task
In tasks like this, you should:
- Identify and describe the main trends.
- Compare and contrast data among different regions.
- Highlight significant points and changes over time.
- Use a range of vocabulary and grammatical structures to express comparisons and superlatives.
Sample Response
Here is a sample response to the prompt provided:
The given table illustrates the levels of air pollution measured in parts per million (ppm) across three regions—North America, Europe, and Asia—from 2000 to 2023.
Overall, there is a clear upward trend in air pollution levels in Asia, while both North America and Europe have experienced a gradual decline in pollution levels over the same period.
In North America, air pollution levels decreased steadily from 250 ppm in 2000 to 200 ppm in 2023. Similarly, Europe saw a reduction from 300 ppm in 2000 to 250 ppm in 2023. These regions have shown a commitment to reducing pollution levels, which may indicate successful implementation of environmental policies.
Contrastingly, Asia experienced a consistent increase in pollution levels, starting at 400 ppm in 2000 and reaching 500 ppm by 2023. The rising trend suggests that industrial activities and urbanization might have contributed to the worsening air quality in this region.
Comparatively, while North America and Europe reduced their air pollution levels by 50 ppm and 50 ppm respectively, Asia’s levels increased by 100 ppm over the same period. This divergence in trends points to significant regional differences in managing air quality.
In conclusion, the data reveals contrasting trends in air pollution levels: a reduction in North America and Europe and a sharp increase in Asia from 2000 to 2023. These differences perhaps reflect varying degrees of policy effectiveness and industrial activity.
