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 4.5)
The flowchart demonstrates the sequential stages involved in the fabric is manufactured from bamboo.
Overall, the manufacturing cycle involves nine main phases, starting from the plants springs and harvested by hand and ending with the fabric is transformed into garments.
At the initial stage, bamboo plants are grown in the field then it is harvested by hand. After that bamboo is cut into strips, it is crushed strips to make liquid pulp. Next, filter separate long fibres from liquid. In the subsequently stage, water and amino oxide are added in soften fibres.
Turning to the next, after that soften fibres make yam.

Task Achievement / Task Response — Band 4.0
The response is severely under-length, containing only 102 words, which fails to meet the 150-word minimum requirement. Consequently, this heavily penalises the task achievement score. While the student attempts to summarise the overall manufacturing cycle ('involves nine main phases') and touches upon initial steps like harvesting and cutting strips, the description is drastically incomplete and trails off before finishing the process. The student misses key intermediate and final steps of the bamboo fabric manufacturing process shown in the diagram. Furthermore, there are awkward phrasing issues in the overview, such as 'the fabric is manufactured from bamboo', which detract from reporting the main features effectively. To improve, the writer must ensure the full length requirement is met and cover all stages of the visual data systematically.
Coherence and Cohesion — Band 5.0
The text attempts a logical progression by using sequencing markers such as 'At the initial stage', 'After that', and 'Next'. However, the organisation breaks down completely as the text stops abruptly after just over a hundred words. Paragraphing is fragmented, with single sentences standing alone as paragraphs ('Turning to the next, after that soften fibres make yam.'), which does not demonstrate a coherent overall arrangement. Cohesive devices are mechanically applied and often grammatically flawed, such as 'In the subsequently stage'. Referencing is also occasionally unclear. To achieve a higher band, the student needs to build cohesive, well-developed paragraphs that guide the reader smoothly through a complete description of the process from start to finish.
Lexical Resource — Band 5.0
The lexical range is very basic and limited, featuring repetitive vocabulary like 'bamboo', 'harvested', 'cut', and 'fibres'. There are noticeable word choice and collocation errors throughout the text, such as 'plants springs' instead of plant growth or shoots, 'crushed strips to make liquid pulp' featuring ungrammatical phrasing, and 'soften fibres' instead of softening the fibres. The misspelling of 'yarn' as 'yam' further indicates lexical and spelling inaccuracies. While the student attempts some less common terms like 'amino oxide' and 'liquid pulp', the frequent errors and restricted range mean the vocabulary is only minimally adequate for conveying simple information.
Grammatical Range and Accuracy — Band 4.0
The text contains a very limited range of grammatical structures, and nearly every sentence exhibits noticeable errors. Examples of severe grammatical inaccuracies include 'the fabric is manufactured from bamboo' (incorrect relative clause or passive structure), 'starting from the plants springs and harvested by hand' (faulty coordination and tense), and 'it is crushed strips to make liquid pulp' (grammatical mismatch). There are also frequent issues with missing prepositions, incorrect word forms such as 'subsequently stage' instead of subsequent stage, and incomplete sentences like 'Turning to the next, after that soften fibres make yam.' These persistent errors cause frequent difficulty for the reader and reflect poor control over basic sentence patterns.
