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 8.5)

The diagram illustrates the process of producing bamboo fabric, from planting bamboo to manufacturing finished clothing.

Overall, bamboo fabric is produced through a nine-stage process, beginning with the cultivation of bamboo plants and ending with the production of clothing. The process involves both natural and industrial stages, including harvesting, crushing, filtering, spinning, and weaving.

Initially, bamboo plants are planted in spring and harvested in autumn once they have matured. The harvested bamboo is then cut into strips, which are subsequently crushed to produce a liquid pulp. After that, the pulp is filtered to separate the long fibres from the liquid.

In the next stage, water and amine oxide are added to the extracted fibres in order to soften them. The softened fibres are then spun into yarn, which is subsequently woven into fabric. In the final stage, the finished fabric is used to manufacture clothing items, such as T-shirts and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 8.0

The response successfully covers all stages of the bamboo fabric manufacturing process. You have identified the main features, starting from cultivation to the final product, and provided a clear overview. The information is logically grouped, and the summary is accurate. To reach a higher band, ensure that you explicitly mention the 'chemical' nature of the process or the specific inputs like 'amine oxide' as a distinct stage, which you have done well. The response is well-balanced and meets all requirements of the task.

Coherence and Cohesion — Band 8.5

The response is well-organized with a clear introduction, a logical body, and a summary. The use of cohesive devices such as 'Initially', 'subsequently', 'After that', and 'In the next stage' creates a smooth flow of information. Paragraphing is used effectively to separate the initial agricultural stages from the later industrial manufacturing stages. The progression of ideas is logical and easy to follow throughout the text.

Lexical Resource — Band 8.0

You have used a good range of vocabulary appropriate for a process description, such as 'cultivation', 'matured', 'extracted', and 'manufacture'. The terminology is precise and fits the context of the diagram well. There are no significant errors in word choice or collocation. To improve further, you could incorporate more sophisticated synonyms or technical collocations to demonstrate a wider range of lexical flexibility.

Grammatical Range and Accuracy — Band 8.5

The response demonstrates a good command of grammatical structures. You have used a mix of simple and complex sentences effectively, such as the passive voice construction 'bamboo plants are planted' and 'the pulp is filtered'. Punctuation is accurate, and there are no major grammatical errors that impede communication. The writing is clear and professional, showing a high level of control over sentence structure.
