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 illustration demonstrates the manufacturing of clothes from bamboo plants.

Overall, it is a nine-step linear process which starts from planting a bamboo plant and ends with production of fabric used for making clothes.

Firstly, bamboo plants are planted in the season of spring, followed by their manual harvesting in the fall season. After that these bamboo sticks are cut into strips to make it easier for the next step, which involves the crushing of these strips to squeeze out the liquid pulp found in them. The juice extracted from these strips is then passed through a filter, which separates fibres from liquid.

These isolated fibres are then added to a mixture of water and amine oxide which softens them. Later a ball of yarn is formed by spinning these softened fibres. To achieve a material like fabric the yarn is woven which in the end is used to make clothes such as shirts and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response successfully covers all stages of the bamboo manufacturing process, from planting to the final product. You have identified the main features and provided a clear, logical summary of the linear process. The overview is concise and effectively sets the stage for the detailed description that follows. To reach a higher band, ensure that you explicitly mention the specific chemical or physical transformations (such as the addition of amine oxide) as key stages rather than just listing them. Overall, the response is accurate and addresses the prompt well.

Coherence and Cohesion — Band 7.0

The response is logically organized, following the chronological order of the diagram. You have used a variety of cohesive devices such as 'Firstly', 'followed by', 'After that', and 'Later' to guide the reader through the process. The paragraphing is appropriate, with a clear introduction and a body that flows well. The progression of ideas is smooth, and referencing is clear throughout the text. To improve further, you could vary the sentence structure slightly more to avoid a repetitive 'subject-verb' pattern at the start of every sentence.

Lexical Resource — Band 6.5

You have used a good range of vocabulary appropriate for a process description, such as 'harvesting', 'extracted', 'isolated', and 'softens'. The terminology is accurate and relevant to the context of manufacturing. There are no significant spelling or word-choice errors. To achieve a higher band, try to incorporate more sophisticated collocations or less common technical terms related to textile production, such as 'cellulose' or 'chemical processing', to demonstrate a wider and more precise lexical range.

Grammatical Range and Accuracy — Band 6.5

The response demonstrates a good control of grammatical structures. You have successfully used passive voice constructions, which are essential for process descriptions (e.g., 'bamboo plants are planted', 'juice... is then passed through'). Most sentences are error-free, and the punctuation is accurate. While the sentence structures are generally clear, they are somewhat simple. To improve, you could incorporate more complex sentence structures, such as using relative clauses or participle phrases to combine ideas more fluidly, which would elevate the grammatical range.
