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 6.5)

The diagram illustrates the sequential, man-made process by which a cloth called fabric is made from a plant, bamboo.

Overall, the process is divided into 9 steps that combine biological growth, industrial processing, and human efficiency. The entire procedure can be divided into three main stages: the growth and harvest of bamboo, the formation of fibres, and the utilization of fabric.

The process starts when bamboo is planted in the spring season, and eventually, when it grows, the farmers harvest it with a hand tool called an arc in the autumn. Following this, bamboo is cut into strips with a circular saw. Once this process is done, the strips are crushed down in order to make liquid pulp. After this, it is passed through the filtration process to separate long fibres from liquid; then the sugar and amine oxide are added to soften fibres.

Finally, the softened fibres are spun to make yarn, then it is woven to make a flat sheet of fabric as a raw material. In the final stage, this fabric is then cut and sewn into different consumer products such as shirts, socks, etc.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The student successfully addresses all parts of the prompt by summarising the main stages of the bamboo fabric manufacturing process. An appropriate overall trend/summary is provided, breaking the process down logically into growth and harvest, fibre formation, and utilisation. Key stages such as planting, harvesting, crushing, filtering, softening, spinning, weaving, and final clothing production are all accurately reported. The information is fully grounded in the provided diagram with no major omissions, earning a solid Band 7.0 for Task Achievement.

Coherence and Cohesion — Band 6.5

The response demonstrates clear logical organisation and progression throughout. The student effectively uses cohesive devices and transition markers such as 'Overall', 'The process starts when', 'Following this', 'Once this process is done', and 'Finally' to guide the reader through the sequential steps. Paragraphing is used appropriately to separate the introduction, overview, and body details. Referencing is generally clear, resulting in a well-structured and coherent piece of writing that meets the Band 7.0 requirements.

Lexical Resource — Band 6.0

The student displays an adequate to good range of vocabulary suited to a process diagram, using terms such as 'sequential', 'industrial processing', 'liquid pulp', 'filtration process', and 'consumer products'. There are a few slightly awkward lexical choices, such as calling the tool an 'arc' instead of a sickle or machete, and stating 'the utilisation of fabric' in the overview rather than manufacturing or production. However, the vocabulary used is sufficient for precision and clarity, comfortably fitting the Band 6.5 descriptor, rounded here to 6.5.

Grammatical Range and Accuracy — Band 6.0

The response features a good mix of simple and complex sentence forms, including subordinate clauses ('when bamboo is planted in the spring season', 'when it grows'). There is good control over grammar and punctuation overall. A few minor slips occur, such as pronoun reference shifts ('After this, it is passed... then the sugar and amine oxide are added to soften fibres', where 'it' is slightly ambiguous), but these errors rarely impede communication and do not obscure meaning, fully supporting a Band 6.5 score.
