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 7.5)

The diagram illustrates the process by which bamboo is transformed into fabric. Overall, the production involves a series of stages, beginning with the cultivation and harvesting of bamboo and ending with the manufacture of finished fabric. The process includes both mechanical and chemical treatments.

Initially, bamboo plants are grown until they reach maturity, after which they are harvested and cut into smaller pieces. These pieces are then crushed mechanically to produce bamboo fibres. At this stage, the fibres undergo chemical treatment, during which they are soaked in a chemical solution. Following this, the material is filtered and purified to remove unwanted substances.

The resulting bamboo pulp is then subjected to further processing to create a suitable material for spinning. This produces fine fibres, which are subsequently spun into yarn. The yarn is then woven together to form fabric. In the final stage, the fabric is treated and processed as necessary before becoming the finished bamboo textile.

Overall, it is a linear process in which raw bamboo is progressively reduced to fibres, converted into yarn, and finally woven into fabric. While the initial stages are primarily concerned with harvesting and mechanical preparation, the later stages involve chemical processing and the transformation of fibres into the final textile.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The student successfully addresses all parts of the task by providing a clear and accurate summary of the process of manufacturing bamboo fabric. The response covers the main features from planting and harvesting to spinning and weaving, and properly identifies both mechanical and chemical stages. Key steps such as crushing the strips, filtering, and softening the fibres are effectively reported in a logical sequence. The overview provided in the introduction and conclusion effectively captures the essence of the diagram. The response meets all requirements for Task Achievement at a high level.

Coherence and Cohesion — Band 8.0

The response is well-organised and exhibits a clear progression from the beginning to the end of the manufacturing process. Ideas are logically sequenced using appropriate transitional phrases like 'Initially', 'At this stage', 'Following this', and 'In the final stage'. Paragraphing is used effectively to group related steps together, enhancing the readability of the text. Cohesive devices are managed well without being intrusive or repetitive, allowing the reader to easily follow the multi-step industrial process.

Lexical Resource — Band 7.0

The student demonstrates a wide and appropriate range of vocabulary pertinent to describing a manufacturing process, using terms such as 'cultivation', 'mechanical treatments', 'chemical solution', 'purified', and 'textile'. Word choices and collocations are generally precise and natural (e.g., 'crushed mechanically', 'spun into yarn'). While there are no striking errors in vocabulary, the range remains slightly conventional rather than fully sophisticated, fitting comfortably into the Band 7 or 8 criteria.

Grammatical Range and Accuracy — Band 7.5

The response features a very good mix of complex and simple sentence structures with a high degree of accuracy. The student employs passive voice structures correctly to describe a process (e.g., 'bamboo plants are grown', 'fibres are soaked', 'yarn is then woven together'). Punctuation and grammatical control are strong throughout, and there are no systematic errors that impede communication. The majority of the sentences are error-free, reflecting a solid command of grammar appropriate for this task.
