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 7.0)

The diagram illustrates the process of making fabric from bamboo.

Overall, the production of bamboo fabric involves several stages, starts with the harvesting of bamboo and ending with the production of the finished fabric.

The bamboo is processed into fibres, which are subsequently converted into yarn and woven to create fabric.

Initially, mature bamboo is harvested and cut into smaller pieces. These pieces are then crushed and processed in order to extract the bamboo fibres. After this, the fibres are cleaned and treated using chemicals to make them suitable for further production. Once the fibres have been prepared, they are dried and transformed into a soft material.

In the next stage, the processed bamboo fibres are spun to produce yarn. The yarn is then prepared for weaving, after which it is woven together to form sheets of fabric. Finally, the fabric is treated and finished so that it can be used for making different textile products. Thus, bamboo undergoes a number of mechanical and chemical processes before becoming usable fabric.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The student covers all the main stages of the bamboo fabric manufacturing process, moving from the initial planting and harvesting in spring and autumn, through crushing, filtering, and softening, to spinning, weaving, and final product creation. A clear overview is provided at the beginning, noting that the process starts with harvesting and ends with finished fabric. However, some minor details from the prompt's steps, such as specific chemical mentions (amine oxide) or the exact layout steps, are generalized. The response successfully highlights the key mechanical and chemical processes required, satisfying the requirements for Task 1 by selecting and reporting the main features effectively.

Coherence and Cohesion — Band 7.5

The response is logically organized with a clear progression from the beginning to the end of the manufacturing process. Paragraphing is used appropriately, with each stage of the process given its own paragraph to group related information. Cohesive devices such as 'Overall', 'Initially', 'After this', 'Once the fibres have been prepared', and 'Finally' are used effectively to guide the reader through the sequence of steps. There is no confusing referencing or mechanical repetition, resulting in a smooth flow throughout the text.

Lexical Resource — Band 6.5

The student demonstrates a sufficient range of vocabulary appropriate for a process diagram, using terms such as 'subsequently', 'extracted', 'transformed', and 'textile products'. There are accurate collocations like 'mature bamboo is harvested' and 'liquid pulp' (implied via crushing). A few minor inaccuracies or generalizations appear, such as stating the fibres are 'dried' which is not explicitly detailed in the prompt, but overall the lexical resource is adequate to convey the steps with some precision and flexibility, fitting the Band 7 profile.

Grammatical Range and Accuracy — Band 7.5

The student uses a good mix of simple and complex sentence structures, incorporating passive voice forms effectively for a process description, such as 'is harvested', 'are then crushed', and 'are spun'. There is a high proportion of error-free sentences, demonstrating good control of grammar and punctuation. Complex structures are handled securely, for example in 'Once the fibres have been prepared, they are dried and transformed into a soft material.' Minor errors are virtually absent, placing this securely in the Band 8 range for grammatical accuracy.
