IELTS Writing Task 1 question

The diagram below shows how fabric is manufactured from bamboo.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

Student answer (Band 5.5)

The following diagram illustrates the manufacturing of fabric and clothes from bamboo.

Overall, the manufacturing process consists of a total of 9 different steps ranging from harvesting of bamboo through physical labour to mixing to various chemicals in laborartory.

First and foremost, bamboo are planted in the Spring season as it would be fully grown until Autumn which is the harvesting season. It is then harvested by many farmers and cut into strips. After which, the strips are crushed to make a liquid pulp and filtered to seperate long fibres from liquid. Water and amine oxide is added to the filtered fibres to soften the fibres and to make them more flexible.

After that process, the soften fibres are spinned to make yam. Finally, the yam is weaved to make fabric from which various clothes, bags and others products can be made. Hence, these are the complete steps on how fabric are produced via bamboo.

Task Achievement / Task Response — Band 6.0

The student successfully covers all parts of the task by reporting the main stages of the bamboo manufacturing process from planting to final products. An overview is provided in the second paragraph, outlining the total number of steps and key aspects of the process. The student selects and reports the key features accurately, noting the progression from harvesting and cutting into strips to crushing, filtering, softening with water and amine oxide, spinning into yarn, and finally weaving into fabric. However, there are minor factual inaccuracies, such as stating that mixing with chemicals happens in a 'laboratory' and mentioning clothes and bags when the diagram specifically depicts a t-shirt and socks. Despite these minor slips, the main features are adequately presented.

Coherence and Cohesion — Band 5.5

The response has a clear overall progression, moving logically through the chronological steps of the manufacturing process. Cohesive devices are used to guide the reader, such as 'First and foremost', 'After which', and 'Finally'. Paragraphing is used reasonably well to separate the introduction, the body of the process, and a concluding summary. However, referencing is occasionally repetitive ('the strips', 'the fibres'), and some transitions feel slightly mechanical. Overall arrangement is coherent and the logical flow is maintained throughout.

Lexical Resource — Band 5.5

The student demonstrates an adequate range of vocabulary for the task, successfully incorporating process-specific terms such as 'manufacturing', 'harvesting', 'crushed', 'filtered', 'pulp', and 'weave'. There are some attempts at less common vocabulary, though this is accompanied by spelling and word-choice errors, such as 'laborartory' (laboratory), 'seperate' (separate), 'spinned' (spun), and 'yam' instead of 'yarn'. While these errors do not impede overall communication, they prevent the lexical score from reaching higher bands.

Grammatical Range and Accuracy — Band 5.0

The response exhibits a mix of simple and complex sentence forms, utilizing passive structures appropriate for a process description, such as 'bamboo are planted' and 'the strips are crushed'. There are several grammatical and spelling errors throughout, including subject-verb agreement issues ('bamboo are planted', 'fabric are produced') and incorrect verb forms ('the soften fibres are spinned', 'the yam is weaved'). Punctuation is generally acceptable, but grammatical inaccuracies occur with sufficient frequency to restrict the score to band 5.5.
