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 stages involved in the production of fabric from bamboo, tracing from plantation in spring to final fabric formation stage.

Overall, the procedure follows linear, multi-stage sequence that begins with planting the bamboo plant in spring and ends with the fabric formation. During these stages, the bamboo is harvested, cut, crushed, filtered and goes through other physical procedures before yielding the final product.

In the initial stages, the bamboo plant is planted specifically in Spring and harvested in Autumn. Once it is gathered, it is then cut into strips through a sharp round cutter, to make a liquid pulp. To separate the long fibres from the liquid the crush strips are filtered.

The remaining stages deal with softening the fibre and final production. Water and amine oxide are added into the filtered fibres to soften it. After that has been done, the soft fibres goes through a spinning process to produce yarn. The yarn is woven to make fabric and eventually the fabric is used to make the end product such as shirts, socks etc.

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The response successfully covers all stages of the bamboo fabric manufacturing process, from planting to the final product. You have identified the main features and provided a clear overview in the introduction. The information is logically sequenced, and the key steps—harvesting, crushing, filtering, chemical treatment, spinning, and weaving—are all mentioned. To reach a higher band, ensure you explicitly highlight the transition points between physical and chemical processing more clearly. The summary is accurate and addresses the requirements of the task effectively, providing a comprehensive overview of the diagram provided.

Coherence and Cohesion — Band 7.0

The essay is well-organized with a clear introduction, overview, and body paragraphs that follow the chronological order of the process. You use cohesive devices such as 'In the initial stages', 'Once it is gathered', and 'The remaining stages' to guide the reader through the process. Paragraphing is used appropriately to separate the early physical stages from the later chemical and manufacturing stages. The progression of ideas is logical and easy to follow throughout the response. The use of referencing is generally clear, contributing to a smooth flow of information.

Lexical Resource — Band 6.0

You demonstrate a sufficient range of vocabulary to describe the process, using terms like 'plantation', 'linear', 'multi-stage', and 'yield'. There is an attempt to use specific terminology related to the diagram, such as 'amine oxide' and 'spinning process'. While the vocabulary is generally accurate, it is somewhat functional. To improve, you could incorporate more sophisticated collocations or precise verbs to describe the transformation of materials, such as 'converting' or 'synthesizing'. The current range is adequate for the task and allows for clear communication of the technical steps involved.

Grammatical Range and Accuracy — Band 6.0

The response uses a mix of simple and complex sentence structures. There are some minor grammatical slips, such as 'the soft fibres goes' (subject-verb agreement error) and 'follows linear, multi-stage sequence' (missing article). However, these errors are infrequent and do not impede communication. You have used passive voice appropriately for a process description, which is a key requirement for this task type. The punctuation is generally accurate, and the sentence variety is sufficient to maintain interest and clarity throughout the description.
