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 of manufacturing fabric from bamboo, beginning with the cultivation of bamboo plants and ending with the production of clothing.

Overall, the process consists of nine stages, starting with growing and harvesting bamboo before it is mechanically and chemically processed into fibres. These fibres are then converted into yarn, woven into fabric, and finally used to make garments.

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. This pulp is passed through a filter to separate the long fibres from the liquid.

In the following stage, the extracted fibres are softened by adding water and amine oxide, creating a material suitable for textile production. The softened fibres are then spun into yarn, after which the yarn is woven into fabric. In the final stage, the finished fabric is used to manufacture a range of clothing items, such as T-shirts and socks.

Overall, the production of bamboo fabric involves a combination of agricultural, mechanical, and chemical processes, transforming raw bamboo into wearable textile products through a series of carefully controlled stages.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The response effectively covers all stages of the bamboo manufacturing process, from cultivation to the final product. You have successfully identified and reported the main features, including the transition from agricultural to mechanical and chemical stages. The overview provides a clear summary of the process, and the information is logically grouped. The response is well-structured and addresses all parts of the prompt without any omissions. To reach a higher band, you could further highlight the specific transformation points, such as the shift from raw material to pulp, to provide even more analytical depth.

Coherence and Cohesion — Band 7.5

The response is well-organized with a clear logical progression. You have used a variety of cohesive devices effectively, such as 'Initially', 'subsequently', 'In the following stage', and 'after which'. Paragraphing is used appropriately to separate the introduction, overview, and the detailed process steps. The flow of information is smooth, and the referencing between stages is clear, making the text easy to follow. The use of linking words is natural and contributes to the overall coherence of the report.

Lexical Resource — Band 7.0

You have demonstrated a good range of vocabulary appropriate for a process description, such as 'cultivation', 'matured', 'subsequently', 'extracted', and 'textile production'. The word choices are precise and contribute to the clarity of the report. There are no significant spelling or word-choice errors. To achieve a higher band, you could incorporate more sophisticated or technical collocations related to industrial manufacturing processes, such as 'raw material extraction' or 'chemical synthesis', to show greater flexibility and precision.

Grammatical Range and Accuracy — Band 7.5

The response displays a good variety of complex sentence structures, including the use of passive voice ('is manufactured', 'are planted', 'is passed'), which is highly appropriate for describing a process. The grammar is accurate throughout, with no major errors that impede communication. Punctuation is used correctly to manage complex sentences. The majority of your sentences are error-free, demonstrating a strong command of English grammar. The control over tense and aspect is consistent and accurate for the task requirements.
