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 flow chart illustrates the step-by-step process of producing fabric from bamboo, starting with cultivation and ending with finished clothing items.

Overall, the process comprises nine distinct stages, categorized into three main phases: agricultural cultivation, chemical processing into raw fiber, and mechanical textile manufacturing.

The initial phase begins in the spring with the planting of bamboo crops. By autumn, the mature bamboo is harvested and subsequently cut into strips using a circular saw. These strips are then crushed to create a liquid pulp mixture.

In the mid-processing phase, the mixture undergoes filtration using a funnel to separate the long bamboo fibers from the excess liquid. Following separation, these extracted fibers are treated with a mixture of water and amine oxide, which serves to soften them into a workable material.

In the final phase, the softened fibers are spun into yarn. This yarn is then woven to produce textile fabric sheets, which are ultimately used to manufacture finished clothing products such as t-shirts and socks.

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 the main features and presented them in a logical, chronological order. The overview provided in the second paragraph is clear and helps the reader understand the structure of the process immediately. All parts of the task are addressed, and the information is accurate based on the provided diagram. To reach a higher band, you could focus on making more explicit comparisons between the stages or highlighting the transformation of the material more dynamically.

Coherence and Cohesion — Band 7.5

The essay is well-organized with a clear progression of ideas. Each paragraph has a distinct focus, which helps the reader follow the process easily. You have used appropriate cohesive devices such as 'subsequently', 'following separation', and 'ultimately' to link the stages of the process. The paragraphing is logical and contributes to the overall flow of the text. The referencing is clear, and the transition between the phases is smooth. The structure is coherent throughout, making the information very easy to digest.

Lexical Resource — Band 7.0

You have used a good range of vocabulary appropriate for a process description, such as 'cultivation', 'subsequently', 'extracted', and 'workable material'. The terminology is precise and fits the context well. There are no spelling errors, and the word choices are generally natural and accurate. To achieve a higher band, you could incorporate more sophisticated collocations or slightly more varied descriptive verbs to describe the physical changes in the bamboo, such as 'pulverized' or 'transformed'. Overall, the lexical range is sufficient and used with good control.

Grammatical Range and Accuracy — Band 8.0

The writing demonstrates a good command of complex sentence structures, such as the use of passive voice ('is harvested', 'are then crushed', 'are treated') which is essential for describing a process. The grammar is highly accurate, with no noticeable errors in tense or punctuation. The sentences are well-constructed and varied in length, contributing to a professional and academic tone. The control over complex structures is consistent, and the text is error-free, which reflects a high level of grammatical competence.
