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 how fabric is made from bamboo.

Overall, the process consists of nine stages, beginning with growing bamboo in the fields and ending with finished clothing reaching customers, involving several mechanical and chemical steps to transform raw bamboo into fabric.

The process begins in the fields, where bamboo plants are planted in spring season. They are then harvested in autumn season and cut into strips. These strips are subsequently crushed to produce liquid pulp, which is then filtered to separate the long fibres from the remaining liquid.

Next, water and amine oxide are added to the filtered pulp in order to soften the fibres, making them suitable for spinning. Once softened, the fibres are spun to make yarn, which is then woven to create fabric. Finally, this fabric is used to manufacture clothing items such as t-shirts and socks, and are ready to be sold to shops and customers.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response successfully covers all stages of the bamboo manufacturing process, from the initial planting to the final product. You have clearly identified the main features and provided a logical summary. The overview paragraph effectively synthesizes the process by noting the nine stages and the combination of mechanical and chemical steps. To reach a higher band, ensure you explicitly highlight the most significant comparisons or contrasts, such as the transition from raw agricultural material to a chemical-based industrial product. The response is well-focused and meets all requirements of the prompt.

Coherence and Cohesion — Band 7.0

The essay is logically organized, with a clear introduction, an overview, and two body paragraphs that follow the chronological order of the process. Cohesive devices such as 'The process begins', 'subsequently', 'Next', and 'Finally' are used effectively to guide the reader through the stages. Paragraphing is appropriate, and the progression of ideas is smooth. To improve further, you could vary your cohesive devices slightly more to avoid a repetitive structure, but the current use is clear and functional throughout the text.

Lexical Resource — Band 6.0

You demonstrate a good range of vocabulary appropriate for a process description, such as 'harvested', 'crushed', 'filtered', and 'soften'. The terminology is accurate and fits the context well. There are no significant spelling errors, and the word choice is generally precise. To achieve a higher score, try to incorporate more sophisticated collocations or less common technical terms related to manufacturing processes, such as 'chemical processing' or 'industrial transformation', to show a greater degree of lexical flexibility.

Grammatical Range and Accuracy — Band 6.5

The writing is largely error-free, with a good mix of simple and complex sentence structures. You use passive voice appropriately for a process description, such as 'bamboo plants are planted' and 'strips are subsequently crushed'. Punctuation is accurate, and the sentence construction is clear. There is a minor subject-verb agreement error in the final sentence ('this fabric... are ready'), which should be 'is ready'. Overall, the control of grammar is strong, and the minor slips do not impede communication.
