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 comprehensive nine-stage manufacturing process required to produce bamboo fabric, guiding the reader from initial agricultural cultivation to the final consumer goods. The process begins in the spring when bamboo plants are cultivated in the ground, followed by their harvesting during the autumn months. Once harvested, the stalks are transported and mechanically cut into smaller, manageable strips. These strips undergo a crushing procedure to transform the raw material into a liquid pulp. Subsequently, the mixture passes through a filtration stage to successfully separate the long fibres from the residual liquid. To further refine the material, water and amine oxide are introduced in the softening phase to treat the fibres. Following this chemical softening, the processed fibres are spun together to create a durable yarn. This yarn is then woven into a versatile fabric through standard textile manufacturing techniques. Finally, the completed bamboo fabric is tailored and assembled into everyday consumer items such as t-shirts and socks, successfully concluding the entire production cycle from raw plant material to a finished wearable product.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The response effectively covers all stages of the bamboo fabric 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 is well-integrated into the introduction, providing a clear summary of the process. To reach a higher band, ensure that you explicitly highlight the most significant stages or transformations, such as the transition from a mechanical process to a chemical one. Overall, the information is accurate and fully addresses the requirements of the prompt.

Coherence and Cohesion — Band 7.0

The response is well-organized, with a clear progression from the beginning to the end of the process. You have used a variety of cohesive devices effectively, such as 'subsequently', 'following this', and 'once harvested', which help the reader follow the sequence of events smoothly. The paragraphing is logical, though the entire response is presented as a single block. While this is acceptable for a short process description, using two paragraphs—one for the initial stages and one for the chemical/textile stages—would further enhance the clarity and structure of your writing.

Lexical Resource — Band 7.5

You have demonstrated a good range of vocabulary appropriate for a technical process description. Terms such as 'cultivated', 'mechanical', 'filtration', 'amine oxide', and 'versatile' are used accurately and in the correct context. The language is precise and contributes to a professional tone. There are no significant errors in word choice or collocation. To improve further, you could incorporate more sophisticated synonyms for common process verbs to demonstrate even greater lexical flexibility.

Grammatical Range and Accuracy — Band 8.0

The grammatical control is excellent throughout the response. You have used a variety of complex sentence structures, including passive voice constructions ('are cultivated', 'are transported', 'are spun') which are highly appropriate for describing a manufacturing process. The punctuation is accurate, and the sentences are error-free. The flow is natural, and the complexity of the structures used demonstrates a high level of proficiency. There are no noticeable grammatical slips, and the writing is consistently clear and precise.
