IELTS Academic Writing Task 1 – Sample Test 31 (Line Graph)
Task Question
The line graph below illustrates the average daily screen time (in hours) among four different age groups (10–19, 20–34, 35–49, and 50+) between 2010 and 2025. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
Figure: Trends in daily screen time (in hours) for four age groups (2010–2025)
Sample Answer (Band 8 – 8.5)
The line graph compares the average number of hours spent on screens per day among four age groups between 2010 and 2025. Overall, all age categories experienced a noticeable rise in screen time over the period, with younger individuals consistently spending more hours on digital devices than older ones.
In 2010, teenagers aged 10–19 recorded roughly 3 hours of daily screen use, which was almost double that of adults over 50, at around 1.5 hours. The 20–34 and 35–49 groups reported similar starting points, close to 2 and 2.5 hours respectively. Over the next decade, usage increased steadily across all age brackets, largely due to the expansion of smartphones and social media.
By 2020, screen exposure among teenagers had exceeded 5 hours daily, while adults aged 20–34 reached nearly 4 hours. Even the 50+ group, initially the least engaged, saw a moderate but continuous climb to about 3 hours by 2025. This convergence suggests a growing dependence on digital entertainment and communication across generations. Despite fluctuations, younger users maintained the highest figures throughout, reflecting stronger digital immersion in their lifestyle.
In summary, the data highlight a universal upward trend in daily screen time between 2010 and 2025, most pronounced among the younger population, though the gap between generations has gradually narrowed.
Analytical Review – IELTS Academic Writing Task 1 (Test 31, Line Graph)
Overall Verdict
Indicative Band: 8.0–8.5
- Task Achievement: Fully covers key trends (steady growth, inter-age comparison, generational convergence).
- Coherence & Cohesion: Smooth progression from 2010 to 2025 with consistent referencing to each age group.
- Lexical Resource: Wide range of precise vocabulary related to technology and social trends (“digital immersion,” “screen exposure,” “convergence”).
- Grammar: Excellent tense control, varied sentence structures, and consistent use of comparatives and passives.
Key Weaknesses
- Lack of data precision: Some values could be specified more clearly (e.g., 3.5 instead of “around 3”).
- Limited use of linking adverbs: Could use more sequencing phrases to enhance flow (“from that point onward,” “meanwhile”).
- Overview compression: Final summary could emphasize intergenerational narrowing more strongly.
- Lexical density: Some expressions are repetitive (e.g., “screen time,” “increase”).
Actionable Improvements
- Add numerical accuracy: Use decimal approximations to demonstrate precision and analytical awareness.
- Broaden lexical scope: Replace repetition with synonyms like “digital activity,” “device use,” or “media consumption.”
- Enhance linking: Insert advanced connectors such as “in parallel,” “by contrast,” or “following this rise.”
- Strengthen overview: Emphasize the shift toward generational convergence and universal tech dependency.
- Integrate insights: Add one interpretive phrase (e.g., “reflecting changing lifestyles”) for higher lexical sophistication.
Stronger Synonyms (Technology Context)
- screen time → digital exposure device usage media engagement
- increase → surge growth upward trend
- decrease → decline drop downturn
- remain stable → plateau level off
- young people → younger demographics adolescent users
Linking Devices (Cohesion)
- Sequence: initially, subsequently, afterwards, toward the end
- Comparison: likewise, similarly, in contrast, whereas
- Result: therefore, consequently, as a result
- Emphasis: notably, significantly, most strikingly
- Interpretation: suggesting that, indicating that, reflecting
- Summary: overall, in summary, to conclude
High-Value Collocations (Technology & Lifestyle)
Band Justification & Path to Band 9
This response demonstrates high-level lexical precision, cohesive structure, and clear analytical insight—consistent with Band 8–8.5 performance. To achieve Band 9, the writer should integrate exact figures and percentage differences, show more evaluative commentary (e.g., link behavioral trends to social change), and diversify connectors and transitions for a smoother narrative flow. Adding subtle interpretive reasoning—such as technological dependence or lifestyle evolution—would lift the report to native-like analytical maturity.
Grammar Targets
- Comparative Clauses: “Teenagers spent far more time on screens than adults.”
- Trend Description: “The figure rose steadily before leveling off in 2025.”
- Complex Passives: “Screen time was significantly influenced by smartphone adoption.”
- Nominalization: “The expansion of digital entertainment contributed to longer usage.”
Checklist Before Submission
- Clear overall trend and comparisons included.
- At least two key figures from the chart referenced accurately.
- Paragraph structure logical and concise.
- Strong topic sentences and varied linking devices.
- Lexical and grammatical range clearly demonstrated.
