IELTS Academic Writing Task 1 – Sample Test46 (Multi-Line Chart)

Task Question

The chart below shows the average daily mobile phone usage in hours among three age groups (Teens, Adults, and Seniors) between 2015 and 2024. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

Average daily mobile phone usage by age group (2015–2024)

Figure: Average daily mobile phone usage trends — LangorAi.com

Sample Answer (Band 8.0–8.5)

The multi-line chart illustrates changes in average daily mobile phone usage for three age categories from 2015 to 2024. Overall, phone use increased for all groups, with teenagers consistently showing the highest usage, while seniors recorded the lowest figures throughout.

In 2015, teenagers used their phones for around 2.0 hours per day, compared with 1.2 hours for adults and slightly below 1.0 hour among seniors. By 2021, there was a marked rise in usage across the three groups: teenagers reached nearly 4.0 hours per day, adults approximately 2.5 hours, and seniors just above 1.5 hours.

By 2024, the upward trend continued. Teen usage peaked at around 5.0 hours daily, while adults reached roughly 3.0 hours. Despite remaining the lowest users, seniors also experienced a steady increase, rising to almost 2.0 hours a day.

Overall, the chart suggests that mobile phones have become increasingly integral to daily life across all ages, though the rate of adoption is strongly age-dependent, with younger individuals adopting more rapidly and extensively.

Analytical Review – IELTS Academic Writing Task 1 (Test 46, Multi-Line Chart)

Overall Verdict

Indicative Band: 8.0 – 8.5

  • Task Achievement: Clearly describes all three age groups across the timeline with logical trend progression.
  • Coherence & Cohesion: Smooth paragraph sequencing (Overview → Early period → Mid → Final) with strong topic flow.
  • Lexical Resource: Effective use of topic vocabulary such as “steady increase,” “peak,” “age-dependent adoption.”
  • Grammar: Accurate complex structures; appropriate use of comparative and superlative forms.

Key Weaknesses

  • Interpretive depth: Analysis does not explain why usage increased differently across ages.
  • Repetitive transitions: Frequent reuse of “overall” and “by 2024” — needs variety.
  • Comparative sharpness: Could better highlight rate changes (e.g., “nearly doubled”).
  • Numerical emphasis: Some figures could be paired with percentage-based contrast for stronger clarity.

Actionable Improvements (High-Impact)

  1. Add causal interpretation: Explain why teens adopt faster (social media intensity / digital-native familiarity).
  2. Sharpen comparisons: Use structures like “X was nearly twice Y”.
  3. Sentence rhythm: Alternate between compact numerical sentences and broader commentary.
  4. Highlight pace of change: “Rapid / moderate / gradual” growth descriptors increase precision.
  5. Concluding insight: Link rising usage to lifestyle & communication shifts.

Stronger Synonyms (Topic-Fit)

  • increase → rise climb grow steadily
  • usage → screen time mobile engagement
  • high → elevated pronounced
  • low → modest minimal
  • difference → gap disparity

Linking Devices (Cohesion Boost)

  • Contrast: whereas, by comparison, on the other hand
  • Trend Shift: gradually, sharply, steadily
  • Time Markers: at the beginning, over the mid-period, by the end
  • Interpretive: this suggests that, this reflects, this indicates

High-Value Collocations (Band 8+)

  • age-dependent adoption pattern
  • digital immersion trend
  • steady upward trajectory
  • technology-driven engagement
  • consistent inter-group disparity
  • behavioral shift across generations

Band-9 Rewrite Upgrades

  • Original: “Teenagers used phones the most.”
    Upgrade: “Teenagers maintained the highest level of mobile engagement throughout the entire period.”
  • Original: “Seniors increased gradually.”
    Upgrade: “Seniors exhibited a gradual yet consistent upward trajectory, reflecting broader digital adoption.”
  • Original: “Adults rose to 3 hours.”
    Upgrade: “Adult usage climbed steadily to approximately 3.0 hours by 2024, indicating mainstream reliance.”

Band Justification & How to Reach 9.0

This essay demonstrates strong task coverage, effective trend description, and a clear structure typical of Band 8.5 work. To reach Band 9, the writer should add interpretive reasoning — explaining underlying causes, such as the role of social media ecosystems, smartphone affordability, or changing communication norms. Band 9 writing does not simply describe what changed but explains why the change matters.

چطور نمره را به 9 برسانیم؟

برای رسیدن به 9 باید فقط «چه چیزی تغییر کرده» را نگوییم؛ بلکه «چرا» و «این تغییر چه پیامدی دارد» را توضیح دهیم.

How to Reach Band 9

Band 9 writing explains why patterns occur, not just what changed.
